Feasibility of Road Longitudinal Profiles for Automated Vehicles Based on Vehicle Dynamics2025-01-715003/19/2025
With the development and maturity of new generation digital technologies such as artificial intelligence, Internet of Things, and 5G mobile communication, their integration with physical products is becoming increasingly seamless. Automobiles serve as a prime example in this regard. In recent years, automated vehicle (AV) technologies have emerged as a prominent focal point, witnessing an escalating acceptance in the market and a growing number of self-driving vehicles on the roads, existing roads are primarily designed for traditional human-driven vehicles (HVs). Due to the differences in perception between automated systems and human drivers, it is essential to assess AVs' feasibility to current road infrastructure. This paper analyzes the safety and comfort of automated vehicles equipped with adaptive cruise control systems (ACC-AVs) on longitudinal road profiles from the perspective of vehicle dynamics. Firstly, a co-simulation platform integrating PreScan, CarSim, and Simulink

Automatic Detection of Dead-End Roads in High-Resolution Satellite Image2025-01-716502/21/2025
There are dead-end roads in the road network, and many of them have the function of indicating specific target clues, which is of great significance in the fields of military, urban construction, and disaster relief and rescue. However, many of the important cut-offs are in mountainous or wilderness areas, and surveying them is difficult and costly. The research objective of this project is to extract the breakpoints in the road network using high-resolution Google satellite imagery, so as to provide clues and indications for the subsequent relevant work. Firstly, the image is corrected and pre-processed to highlight road edge information.Then the phase grouping method is improved by setting a double-angle threshold, filtering the edge operator to reduce the calculation error of the gradient angle, and the road network is extracted by the improved phase grouping method.

RESEARCH OF THE EFFECTS OF INTEGRATION INTO ARMOR ON THE PERFORMANCE OF SPINTRONIC MICROWAVE DETECTORS2024-01-333411/15/2024
ABSTRACT The authors studied the effects of different types of armor on the performance of spin-torque microwave detectors (STMD). Working prototypes of novel nano-sized spintronic sensors of microwave radiation for battlefield anti-radar and wireless communications applications are being integrated into Sensor Enhanced Armor (SEA) and Multifunctional Armor (MFA) and tested in SEA-NDE Lab at TARDEC. The preliminary theoretical estimations have shown that STMD based on the spin-torque effect in magnetic tunnel junctions (MTJ), when placed in the external electromagnetic field of a microwave frequency, can work as diode detectors with the maximum theoretical sensitivity of 1000 V/W. These STNO detectors could be scaled to sub-micron size, are frequency-selective and tunable, and are tolerant to ionizing radiation. We studied the performance of a STMD in two different dynamical regimes of detector operation: in well-known traditional in-plane regime of STMD operation and in recently

SIMULATION FOR VEHICLE-TO-VEHICLE AND VEHICLE-TO-GRID RESOURCE SHARING ANALYSIS2024-01-344411/15/2024
ABSTRACT A simulation capable of modeling grid-tied electrical systems, vehicle-to-grid (V2G) and vehicle-to-vehicle(V2V) resource sharing was developed within the MATLAB/Simulink environment. Using the steady state admittance matrix approach, the unknown currents and voltages within the network are determined at each time step. This eliminates the need for states associated with the distributed system. Each vehicle has two dynamic states: (1) stored energy and (2) fuel consumed while the generators have only a single fuel consumed state. One of its potential uses is to assess the sensitivity of fuel consumption with respect to the control system parameters used to maintain a vehicle-centric bus voltage under dynamic loading conditions.

Designing an Uncrewed Aircraft Systems Control Model for an Air-to-Ground Collaborative System01-17-02-001402/19/2024
Abstract In autonomous technology, uncrewed aircraft systems have already become the preferred platform for the research and development of flight control systems. Although they are subjected to following and satisfying complicated scenarios of control stations, this high dependency on a specific control framework limits them in their application process and reduces the flight self-organizing network. In this article, we present a developed multilayer control system protocol with the additional supportive manned aircraft layer (Tender). The novelty of the introduced model is that uncrewed aircraft systems are monitored and navigated by the tender, and then based on the suggested scheme, data flows are controlled and transferred across the network by the developed cloud–robotics approach in the ground station layer. Therefore, it has been tried to design a semi-autonomous control network to gather data that combines human observation and the automotive nature of uncrewed aircraft

Automated Charging Methodology for Fleet Operated EV Buses to Reduce Down Time and Increase Safety at Charging Station2024-26-011201/16/2024
Prime concern for electric vehicle where the application of the vehicle is public transport, is the charging of vehicle and operation of its infrastructure. Such an example of operating the EV buses is under the GCC (gross cost contract) model, with high operation time and comparatively lesser time for charging. It is challenging to meet these requirements. To counter this situation in fleet operated busses it is proposed to adapt an automated charging method which involves minimum man power intervention and automated mechanism to connect & disconnect the charging connectors. This paper proposes an automated pantograph mechanism based method of charging EV buses, meeting requirements as per SAE J3105 & ISO 15118 standards, which would be an ideal way to resolve the current situation. In the above mentioned pantograph type charging, the charging station or depot will have an infrastructure including charger whose input will be from grid, and the charging dispenser will be pantographs

Safety Spacing Control of Truck Platoon Based on Emergency Braking under Different Road Conditions10-07-01-000510/13/2022
Vehicle platooning reduces fuel consumption, improves traffic throughput, and achieves smaller intervehicle spacing which increases the probability of danger during platoon braking. This article presents a sliding mode control based on the safety spacing policy for longitudinal control of a connected truck platoon with a focus on the predecessor following interactions. In particular, the modified safety spacing policy considering the intervehicle braking information communication delay, the sluggish nature of the brake actuator, the road conditions on each vehicle as well as the vehicle motion state is proposed. On this basis, an acceleration sliding mode controller is proposed, which takes into consideration the spacing error and speed error of the intervehicle, and the control error is zero, so as to obtain the expected acceleration of each vehicle in the platoon. Simulation results of truck platooning with six trucks using TurckSim have demonstrated the effectiveness of the proposed

Engine Overheating Prediction with Machine Learning Using Gaussian Mixture Model (GMM)2022-28-000710/05/2022
The Advancement in Connected vehicles Technology in recent years has propelled the use of concepts like the Internet of Things (IoT) and big data in the automotive industry. The progressive electrification of the powertrain has led to the integration of various sensors in the vehicle. The data generated by these sensors are continuously streamed through a telematics device on the vehicle. Data analytics of this data can lead to a variety of applications. Predictive maintenance is one such area where machine learning algorithms are applied to relevant data to predict failure. Field vehicle malfunction or breakdown is costly for manufacturers’ aftermarket services. In the case of commercial vehicles, downtime is the biggest concern for the customer. The use of predictive maintenance techniques can prevent many critical failures by tending to the root cause in the early stages of failure. Engine overheating is one such problem that transpires in diesel engines. Overheating of an engine

Design and Development of a Virtual Autonomous System2022-01-507210/03/2022
An autonomous vehicle or a driverless vehicle is a ground vehicle that is capable of sensing its environment and moving safely with little to no human input. The present study aims to validate existing literature on vehicle following, emergency braking, lane changing, overtaking, and jerk trajectory with regard to autonomous vehicles. By using the jerk trajectory equation, we are able to optimize it by implementing a complete overtaking procedure. We are also able to compare the variation in both the dynamic and kinematic bicycle model for the same vehicle and traveling the same distance. A new kinematic bicycle model is built, which is more simple to construct. This project is performed using MATLAB and Simulink for creating and modifying the system blocks. There has also been an integration of 3D visualization software such as VR sink and Unreal Engine. We construct the vehicles by simple transfer functions, ACC and PID as the main system blocks for vehicles 1, 2, and 3, respectively

SECURING CAN NETWORKS IN COMMERCIAL VEHICLES22TOFHP10_0210/01/2022
A CAN transceiver with built-in security functions can avoid the complexity of end-to-end security solutions that are especially hard to implement on CVs. Commercial road vehicles are the backbone of the modern consumer economy. Almost any business from construction, to energy, to online retail at some point relies on the delivery of goods by commercial vehicles, which in turn are becoming increasingly connected both to the external world and to each other via telematics. This enables CV owners to optimize and manage their fleets via platooning for safety and efficiency improvements as well as cost and fuel-consumption reduction to meet the increasingly stringent CO2 emissions requirements necessitated by climate change. However, the increased connectivity brings with it an increase in cyberattack surfaces and CV fleets are prime targets for cybercrime due to the high value of the cargo they carry, and their importance to large businesses and the greater economy.

Impact of Positioning Uncertainty on Connected and Automated Vehicle Applications12-06-02-001008/05/2022
Many Connected and Automated Vehicle (CAV) applications assume that highly accurate positioning is always available. However, this is not the case in many real-life situations (e.g., when a satellite-based navigation system is used for positioning in urban canyons). Furthermore, very little research has been conducted to evaluate the impacts of position accuracy on CAV applications at the traffic level. The objective of this article is to investigate the positioning errors that could be tolerated by a sample of CAV applications. Toward this end, we (1) perform a general analysis of the positioning requirements of selected safety-, mobility- and environmental-focused applications and (2) examine in greater detail the effect of positioning errors on two representative CAV applications, Eco-Approach and Departure at Signalized Intersections (EAD) and High-Speed Differential Warning (HSDW). The results of (1) indicate that lane-level positioning accuracy is sufficient to enable most CAV

Toward an Automated Scenario-Based X-in-the-Loop Testing Framework for Connected and Automated Vehicles12-05-04-003006/27/2022
Emerging technologies for connected and automated vehicles (CAVs) are rapidly advancing, and there is an incremental adoption of partial automation systems in existing vehicles. Nevertheless, there are still significant barriers before fully or highly automated vehicles can enter mass production and appear on public roads. These are not only associated with the need to ensure their safe and efficient operation but also with cost and delivery time constraints. A key challenge lies in the testing and validation (T&V) requirements of CAVs, which are expected to be significantly higher than those of traditional and partially automated vehicles. Promising methodologies that can be used toward this goal are scenario-based (SBT) and X-in-the-Loop (XiL) testing. At the same time, complex techniques such as co-simulation and mixed-reality simulation could also provide significant benefits. Nevertheless, the benefits of individual solutions are likely to be significantly smaller, if considered

Real-Sim Interface: Enabling Multi-resolution Simulation and X-in-the-Loop Development for Connected and Automated Vehicles12-05-04-002606/27/2022
Connected and automated vehicles (CAVs) can bring safety, mobility, and energy benefits to transportation systems. Ideally, CAV applications would be fully evaluated and validated prior to real-world implementation. However, many technical challenges in both software and hardware hinder the process. To comprehensively evaluate all aspects of CAV applications, an integrated evaluation environment is needed with various simulation tools from different domains. In the current literature, there lacks a well-developed interface to enable multi-resolution simulation of vehicle, traffic, virtual environment, and hardware-in-the-loop (HIL) simulation. In this work, a modular and flexible interface is developed to enable multi-resolution vehicle and traffic co-simulation for CAV applications. This interface is built upon Oak Ridge National Laboratory’s (ORNL’s) Real-Sim approach, can support various simulation tools and real-time X-in-the-loop (XIL) simulations, and is based on network

A hybrid sensor-fusion system to locate the Electric gridlines by UAV for range extension in Urban areas2022-26-114905/26/2022
This paper explores the efficacy and efficiency of a system for the effective location of electric gridlines during daytime and night-time by the onboard and offboard transceivers of UAV through vehicle to infrastructure communication. The usage of electric gridlines in urban areas helps to extend the range of the UAVs by charging the onboard battery using an extended arm. The same arm can also be used for direct propulsion of the motors onboard UAV, thereby minimizing the reliance on battery. UAVs with advanced Image processing algorithms are utilized in the inspection of the electric grid lines themselves in the Power industry. The camera based algorithms are not effective during night-time when the gridlines are near invisible. This can be mitigated by evaluating light in other spectral ranges, but this would add to the load of the UAV. We propose a system which combines multiple information sources and helps locate the gridlines for range extension, specifically for the delivery of

Demonstration of energy consumption reduction in class 8 trucks using eco-driving algorithm based on on-road testing2022-01-015703/29/2022
Vehicle to Everything (V2X) communication has enabled on-board access to the information from other vehicles and infrastructure. This information, traditionally used for safety applications, is increasingly being used for improving fuel economy of the vehicles [1, 2, 3, 4, 5]. This work aims at demonstrating energy consumption reduction in heavy/medium duty vehicles using the eco-driving algorithm. The algorithm is enabled by V2X communication and uses data contained in basic safety messages (BSMs) and signal phase and timing (SPaT) to generate an energy-efficient velocity trajectory for the vehicle to follow. A ~25.7 km (16-mi) urban corridor in Bexar County, Texas, was modeled in a microscopic traffic simulation package and calibrated to match real-world conditions. For the trucks using this algorithm, a nominal reduction of 7% in energy consumption and 6% in trip time was observed in simulation. This was validated by on-track testing of a pair of velocity profiles. The track testing

Numerous studies have demonstrated significant energy reduction for an ego vehicle by up to 20% leveraging Vehicle-to-Everything (V2X) technologies [1, 2, 3, 4]. Some studies have also analyzed the impact of such vehicles on the energy consumption of other vehicles in a suburban or a highway corridor [5, 6]. Southwest Research Institute (SwRI), in collaboration with Continental and Hyundai, is currently working on a Department of Energy funded project that is focused on quantifying the impact of multiple ego vehicles (smart vehicles) on the total energy consumption of the corridor under various traffic conditions, vehicle electrification level, vehicle-to-vehicle (V2V) technology penetration, and the number of smart (ego) vehicles in an urban setting. A six-kilometer-long urban corridor from Columbus, Ohio was modeled and calibrated via real-world data in PTV Vissim traffic microsimulation software. Five forward-looking powertrain models, consisting of two battery electric vehicles

A Novel Vehicle-to-Vehicle Fast Charging Control System Utilizing Motor and Inverter in EV2022-01-019403/29/2022
As electric vehicles become more widespread, such vehicles may be subject to “range anxiety” due to the risk of discharging during driving or the discharging when left unused for a long period. Accordingly, a vehicle equipped with a mobile charger that can provide a charge in an emergency. The vehicle with the mobile charger is usually composed of a large capacity battery, a power converter in a small truck. However, the large capacity battery and the power converter are disadvantageous in that they are large in size and expensive and should be produced as a special vehicle. In this paper, we propose a method to solve the problem using an internal EV system without requiring an additional power generation, battery and a charging-and-discharging device. The method is a novel Vehicle-to-Vehicle fast charging control system utilizing motor and inverter in EV.

The Effects of Measurement Uncertainty and Error on Operational Safety Assessment (OSA) Metrics2022-01-098503/29/2022
As the deployment of automated vehicles (AVs) on public roadways expands, there is a growing need to establish metrics that can be used to evaluate vehicle operational safety. The set of Operational Safety Assessment (OSA) metrics previously proposed by the Institute of Automated Mobility (IAM) are a step towards achieving this goal. The safety envelope OSA metrics can be computed using kinematics derived from video data captured by infrastructure-based cameras and thus do not require vehicle-to-infrastructure (V2I) connectivity, though connectivity could enhance kinematic data accuracy. However, the calculation of some metrics includes certain vehicle-specific parameters that must be assumed or estimated if they are not communicated directly by the vehicle. Uncertainty and errors in kinematic measurements and assumed parameters can affect the accuracy and ultimately the utility of the safety envelope OSA metrics. This paper investigates how uncertainties and errors in measured and

Managing Trust along the CAN Bus2022-01-014303/29/2022
Multiple approaches have been created to enhance intra-vehicle communications security over the past three decades since the introduction of CAN. The twin pair differential-mode communications bus is tremendously robust in the face of interference, yet physical access to the bus offers a variety of potential attack vectors whereby false messages and/or denial of service are easy to achieve. This paper seeks to evaluate extensions of a common-mode watermark-based authentication technique recently developed to improve authentication on the CAN bus by considering the watermark as a side-channel communications means for high value information. We also describe a variety of higher layer algorithms, with benefits and pitfalls, for employing the watermark as a physical-layer firewall. All of these results are backed by a software-defined radio (SDR) based hardware testbed.

Routing and Security Mechanisms Design for Automotive TSN/CAN FD Security Gateway2022-01-012203/29/2022
With the explosion of in-vehicle data, Time Sensitive Network (TSN) is increasingly becoming the backbone of the in-vehicle network to ensure deterministic real-time communication and Quality of Service (QoS). However, legacy buses such as CAN FD and LIN will not disappear for a long time in the future. The gateway can be connected to many different protocols and is an important component in the security and functional safety of the communication process. In this paper, the recommended Electrical/Electronic Architecture is first given and the use cases for the TSN/CAN FD gateway are illustrated. Then, a TSN/CAN FD routing mechanism is designed and security mechanisms are deployed. The routing mechanism includes the protocol conversion module, queue cache module, and forwarding scheduling module. The protocol conversion module maps the priority of CAN FD messages to TSN messages and unpacks or packs the messages according to the routing table. Dynamic space of queue is utilized in the

Key Fob Relay Attack Prevention With Pattern Matching2022-01-013203/29/2022
Key FOB relay attack is new form of cybersecurity attack which was demonstrated by hacker on many vehicles from different manufacturers. In this type of attack the hacker works in pair. 1 hacker will be near the vehicle and other is positioned near the user who has keys. Hacker initiates the communication between key fob and vehicle by catching signals with RF receiver and retransmitting signals through the Signal generator. This way hacker creates a RF bridge between vehicle and key fob. Since both ECU’s are communicating with each other they assume that user is near car. After security handshake car is unlocked and engine can also be started This paper is a new solution which will provide some degree of defense for this attack. This logic is built around the power level of received signal between the vehicle and key fob. Both vehicle ECU and key fob will have capability to evaluate the power level of received RF signal. Vehicle ECU and KeyFob Ecu’s will evaluate the power level of

Accelerating In-vehicle Network Intrusion Detection System using Binarized Neural Network2022-01-018603/29/2022
Modern vehicles are utilizing more software modules and interfaces while new risks and attacks are emerging and threatening the security of vehicles. Researchers demonstrate that in-vehicle networks have become a target of vehicle attackers. Controller Area Network (CAN), the de facto standard for in-vehicle networks, has insufficient security features and thus is inherently vulnerable to various attacks. Intrusion detection systems (IDSs) based on advanced deep learning methods, such as Convolutional Neural Network (CNN) and Recurrent Neural Network (RNN), have been proposed to protect CAN bus from attacks. However, those models generally introduce high latency and require considerable computing resources. To accelerate intrusion detection and also reduce both latency and model size, we propose a new IDS system based on Binarized Neural Network (BNN). As BNN uses binary values for activations and weights rather than full precision values, it usually results in faster computation and

Computer Vision-Based V2X Collaborative Perception2022-01-008203/29/2022
In this paper, we present the computer vision-based V2X collaborative perception. Our system uses a forward-looking camera in the Host Vehicle. The camera detects road users such as pedestrians, vehicles, and motorcycles. Such information includes object type, relative location, direction, and speed. This information is used to compose proxy Basic Safety Messages on behalf of the detected objects. Early adopters of the V2X technology can experience the benefits of enhanced V2X market penetration. The outcome of adopting our concept will result in an inflated V2X market penetration rate leading to earlier safety, mobility, and situational awareness improvements. The ultimate goal is for all road participants to be fully aware of each other. The novelty of our work is the integration of computer vision-based detection and LTE-V V2X communications, in addition to implementing the concept for pedestrians and bicyclists. A similar concept will work for other sensors such as radar and LiDARs

Green Light Optimized Speed Advisory with Traffic Preview2022-01-017403/29/2022
By utilizing the vehicle to infrastructure communication, the conventional Green Light Optimized Speed Advisory (GLOSA) applications give speed advisory range for drivers to travel to pass at the green light. However, these systems do not consider the traffic between the ego vehicle and the traffic light location, resulting in inaccurate speed advisories. Therefore, the driver needs to intuitively adjust the vehicle's speed to pass at the green light and avoid traffic in these scenarios. Furthermore, inaccurate speed advisories may result in unnecessary acceleration and deceleration, resulting in poor fuel efficiency and comfort. To address these shortcomings of conventional GLOSA, in this study, we proposed the utilization of collaborative perception messages shared by smart infrastructures to create an enhanced speed advisory for the connected vehicle drivers and automated vehicles. Two different algorithms were designed by utilizing the available traffic preview (Signal Phase and
