Object Tracking Comparison for Automated Vehicles Using MathWorks Toolsets2021-01-011004/06/2021
Object trackers are a tool to achieve accurate object state estimation over time. Due to their complexity, a framework to experiment with different variations of trackers and their subcomponents is desired. This drove the authors research and experimentation with object tracking using MathWorks toolsets. In this paper, three object trackers - Point Target Tracker (PTT), Gamma Gaussian Inverse Wishart Probability Hypothesis Density (GGIW-PHD), and Gaussian Mixture Probability Hypothesis Density (GM-PHD) - are compared in simulation for track statistics and object/track accuracy. The results show that a rectangular GM-PHD multi object tracker outperforms the other trackers. A follow up is shown using real-world data and the process used to get the sensor data into the appropriate MathWorks format. The impact of COVID-19 prevented the collection of ground truth data so the real-world data cannot be compared using the same metrics. For this reason, the simulation portion of this paper will

Research on Effect of Dynamic Working Condition on Electrochemical Impedance2021-01-074704/06/2021
Impedance is an important parameter of power lithium-ion batteries, which can represent battery characteristics and can also be used as an indicator for battery fault diagnosis. Since Electrochemical Impedance Spectroscopy (EIS) includes various electrode processes and information, it is more significant and worthwhile for lithium-ion batteries research. However, it is quite difficult to attain EIS online because of the nonlinear characteristics of batteries. Therefore, this paper focus on studying the nonlinear impedance characteristics of lithium-ion batteries and proposing a new method to calculate the EIS online based on Fast Fourier Transform (FFT). Data similarity analysis is used to study the influence of resting time, excitation current amplitude, bias current amplitude and the state of charge (SOC) on the impedance quantitatively. Further research finds that the amplitude of impedance, voltage and current in frequency domain all conform to the law of power function well within

Fusing Offline and Online Trajectory Optimization Techniques for Goal-to-Goal Navigation of a Scaled Autonomous Vehicle2021-01-009704/06/2021
Enabling self-driving vehicles to efficiently and autonomously navigate through an obstacle-filled environment remains a topic of significant contemporary research interest. Motion-planning frameworks, encapsulating both path- and trajectory-planning, have played a dominant role in realizing the deployment of a “sense-think-act” intelligence for autonomous vehicles. However, verification and validation of such intelligence on actual self-driving autonomous vehicles has been limited. Simulation-based verification and validation has the advantage of permitting diverse scenario-based testing and comprehensive “what-if” analyses - but is ultimately limited by the simulation fidelity and realism. In contrast, testing on full-scale real-world systems is constrained by the usual challenges of time, space, and cost engendered in reproducing diverse scenarios in practice. Further, motion-planning frameworks often engender a mixture of global-planning (typically performed offline) coupled with a

An Online Coverage Path Planning Method for Sweeper Trucks in Dynamic Environments2021-01-009504/06/2021
In this paper, a novel online coverage path planning (CPP) method for autonomous sweeper trucks in closed areas is proposed. This method can efficiently generate executable paths for sweeper trucks that cover all feasible uncleaned areas without getting tracked in dead-end, i.e., no backward behaviors required and avoid dynamic obstacles. To reach that end, a modified biological inspired neuron network method considering vehicle constrains is developed, where the dynamic of each neuron is determined by the shunting function. The path will be iteratively generated based on local neuron dynamics. In order to avoid dead-end, a detour algorithm combing with back iteration is introduced to search the nearest uncleaned area that can be reached within vehicle constrains. The proposed method is empirically approved to be computationally efficient and adaptive to maps with arbitrary shapes. The feasibility of generated paths is validated in simulations, where the pure pursuit method is applied

Vehicle Safety Communications Landscape Clarifies with Controversial FCC Ruling21AVEP01_0601/01/2021
The vehicle-to-everything communications-technology debate is “solved” by federal regulators - and cellular vehicle-to-everything (C-V2X) appears to be the winner. After years of transportation-industry tussle over competing technologies to enable communications between vehicles and a “connected” environment, the Federal Communications Commission (FCC) has decided the matter. On Nov.18, 2020, the FCC ruled it will allow a portion of the 5.9-GHz “Safety Spectrum” long reserved for the transportation sector to be allocated to unlicensed private usage such as Wi-Fi internet connectivity. The ruling effectively eliminates the future for Wi-Fi-based Dedicated Short-Range Communications (DSRC) and locks in the advancing alternative, cellular vehicle-to-everything (C-V2X). Despite many experts' opinion that the decision to now limit transportation communications to just the upper 30 MHz of the 75-MHz spread within the 5.9-GHz (5.850-5.925 GHz) Safety Spectrum has not been sufficiently

Communication for Wireless Power Transfer Between Light-Duty Plug-in Electric Vehicles and Wireless EV Charging StationsJ2847/6_202009 (Current)09/29/2020
SAE J2847/6 establishes minimum requirements for communication between an electric vehicle and an inductive battery charging system for wireless power transfer (WPT). Where relevant, this document notes—but does not formally specify—interactions between the vehicle and vehicle operator. This document leverages the work of the SAE J2954 Alignment and Controls Sub-Team in the Wireless Power Transfer and Alignment Task Force by extending a JSON-based message set (protocol) originally developed to bench test wireless energy transfer interoperability between unmatched Ground Assembly (GA) and Vehicle Assembly (VA) systems (i.e., components manufactured by different companies). SAE J2847/6 furthers that work by adding messages sufficient to indicate that proper coil alignment has been achieved, initialize the sub-systems for wireless charging, ramp-up to full power, perform active wireless power transfer, and terminate the WPT session.

Engine-in-the-Loop Study of a Hierarchical Predictive Online Controller for Connected and Automated Heavy-Duty Vehicles2020-01-059204/14/2020
This paper presents a cohesive set of engine-in-the-loop (EIL) studies examining the use of hierarchical model-predictive control for fuel consumption minimization in a class-8 heavy-duty truck intended to be equipped with Level-1 connectivity/automation. This work is motivated by the potential of connected/automated vehicle technologies to reduce fuel consumption in both urban/suburban and highway scenarios. The authors begin by presenting a hierarchical model-predictive control scheme that optimizes multiple chassis and powertrain functionalities for fuel consumption. These functionalities include: vehicle routing, arrival/departure at signalized intersections, speed trajectory optimization, platooning, predictive optimal gear shifting, and engine demand torque shaping. The primary optimization goal is to minimize fuel consumption, but the hierarchical controller explicitly accounts for other key objectives/constraints, including operator comfort and safe inter-vehicle spacing.

A Method for Simultaneous State of Charge, Maximum Capacity and Resistance Estimation of a Li-Ion Cell Based on Equivalent Circuit Model2020-01-118204/14/2020
Accurate estimation of the State of Charge (SOC), maximum capacity (Qmax) and internal resistance are critical for battery monitoring, i.e., determining the status, health, and performance figures of a battery. SOC is a key indicator of the instant status for battery systems, while Qmax and internal resistance are related to the capacity fade (SOHQ) and power fade (SOHP) respectively, which represent the abilities of a battery to store energy, retain charge over extended periods and provide the required power for acceleration, etc. Traditional methods using complex models and look-up tables have high computation requirements which makes them unsuitable for online applications. In this paper, we propose a simple method for simultaneous SOC, Qmax and internal resistance estimation based on a second-order equivalent circuit model (ECM). A Variable Model framework based Adaptive Extended Kalman filter (VM-AEKF) is implemented for joint SOC and model parameter estimation where the VM

Enhancing Driver Awareness Using See-Through Technology2018-01-061104/03/2018
This paper presents a real-time application of see-through technology using computer vision (e.g., object detection) and Vehicle-to-X (V2X) communication (e.g., Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I)). Each access point (AP) was connected to Chattanooga’s fiber optics internet, supporting a data transfer rate up to 10-Gbps. Using a 5Ghz frequency, vehicular communications were set up with a seamless handover for transferring real-time data. Two web cameras acting as clients were mounted on the windshield of two of three vehicles to send image data to the offsite server. Using multi-threaded programming, both image feeds were processed simultaneously. Once the server received the images, it performed an object recognition algorithm on each image using a convolutional neural network (CNN). Post- identification, the images from the second vehicle were sent and overlaid dynamically to the third vehicle’s image. This repetitive overlapping of images allowed the third

Line Scan CamerasTBMG-2783211/01/2017
Area array and line scan cameras are each suited for unique machine vision applications. Area array cameras, for all intents and purposes, are “conventional” cameras that use sensors with two-dimensional pixel arrays. The square or rectangular shaped sensor captures an image in a single pass with the resulting image having a width and height corresponding to the number of pixels on the sensor, for example, 640x480. Because of this, area array cameras are ideal for machine vision tasks where objects are small or have approximately the same size in both dimensions. However, the size of PCBs, LCD panels, and wafers has increased beyond the speed, accuracy, and resolution capabilities of many area array cameras. Line scan cameras offer a better solution.

Ad Hoc Selection of Voice Over Internet StreamsTBMG-2687305/01/2017
NASA seeks interested parties to license the Ad Hoc Selection for Voice Over Internet (VoIP) Streams technology developed by engineers at Johnson Space Center. This technology features the ability to select specific audio streams from one or more sources and then convert them into a multicast to the user's audio player. This selection ability benefits the user by allowing a wide range of information and/or data to be monitored from a remote location using existing network technologies in near real time. For example, a user with a personal computer equipped with special-purpose audio player software first needs to launch the program and provide an identification and a password. Once both access control checks are completed, the audio software graphic is displayed, including audio stream and volume control buttons. The user can now select up to 21 streams to monitor simultaneously.
Open Mission Control Technologies (Open MCT) WebTBMG-2684705/01/2017
The fundamental idea behind the Mission Control Technologies (MCT) project is to build software from pieces that can be assembled by end users to create integrated visualizations. Applications are eliminated in favor of compositions of live data objects that can be combined in different ways for different users and missions as required, in contrast to the more traditional software development method of pre-determining functionality and building a monolithic application. This new approach has the potential to change how users design, deploy, and maintain mission system software.
Cyber Security in the Automotive Domain – An Overview2017-01-165203/28/2017
Driven by the growing internet and remote connectivity of automobiles, combined with the emerging trend to automated driving, the importance of security for automotive systems is massively increasing. Although cyber security is a common part of daily routines in the traditional IT domain, necessary security mechanisms are not yet widely applied in the vehicles. At first glance, this may not appear to be a problem as there are lots of solutions from other domains, which potentially could be re-used. But substantial differences compared to an automotive environment have to be taken into account, drastically reducing the possibilities for simple reuse. Our contribution is to address automotive electronics engineers who are confronted with security requirements. Therefore, it will firstly provide some basic knowledge about IT security and subsequently present a selection of automotive specific security use cases.

Hardware/Software Co-Design of an Automotive Embedded Firewall2017-01-165903/28/2017
The automotive industry experiences a major change as vehicles are gradually becoming a part of the Internet. Security concepts based on the closed-world assumption cannot be deployed anymore due to a constantly changing adversary model. Automotive Ethernet as future in-vehicle network and a new E/E Architecture have different security requirements than Ethernet known from traditional IT and legacy systems. In order to achieve a high level of security, a new multi-layer approach in the vehicle which responds to special automotive requirements has to be introduced. One essential layer of this holistic security concept is to restrict non-authorized access by the deployment of embedded firewalls. This paper addresses the introduction of automotive firewalls into the next-generation domain architecture with a focus on partitioning of its features in hardware and software. Based on the deployment of the firewall in the in-vehicle network, the corresponding adversary model and automotive

Generalized Query Tool for Accessing the Database of the Mars Relay Operations Service (MaROS)TBMG-2636402/01/2017
The Generalized Query Tool for accessing the database of MaROS can be utilized in three modes: (1) batch mode where a user's authentication data is inserted directly along with a desired query to the database, (2) interactive mode where a desired query is known and can be entered directly, and (3) interactive mode with a query “wizard” that walks a user through the steps needed to construct a valid query to the database. In all three cases, the successful execution of the script results in data from the MaROS database being made available to the user in a comma-separated output file. For new users, it is recommended to use the third mode to build a sample query and then tailor that as desired for use with the first or second modes.

An Estimation Method of Vehicle Position for Automated Driving with GNSS2016-01-016604/05/2016
Accuracy of positioning with GNSS (Global Navigation Satellite System) has been improved in recent years. Especially in Japan, high accuracy GNSS service, QZSS (Quasi Zenith Satellite System), will start in 2018 and the first QZS, “MICHIBIKI” has been already launched. They will broadcast correction data which enhances GNSS performance and realize cm-order positioning. In this paper, we, Mitsubishi Electric develop the estimation algorithm of vehicle position and attitude and also adapt the algorithm to a test vehicle which can trace automatically the calculated path with EPS (Electric Power Steering) and high accuracy GNSS. Although the GNSS receiver calculates the longitude and latitude of the vehicle every second, it is not enough to control vehicle dynamics smoothly. So we estimate vehicle position and attitude of the vehicle with GNSS and vehicle sensors in high frequency. Using them, we calculate the target path as cubic function from road dot sequence in a body fixed coordinate

Guaranteed Timing Behavior Begins with an Established Ethernet Backbone2016-01-006104/05/2016
Increasingly, Ethernet is being used in automotive as a vehicle network backbone. It is ideal for service-oriented communications; streamed communications, such as Audio/Video Bridging (AVB) [1]; and Diagnostics over Internet Protocol (DoIP) [2] communications - areas in which high-bandwidth and reliable performance are essential. Designers are accustomed to network communication systems CAN, LIN, and FlexRay, but how will the timing performance be verified in an Ethernet network? This paper looks at network-wide timing analysis challenges where a mixture of CAN, FlexRay, and Ethernetbased busses co-exist. It is also worth noting that the AUTOSAR standard [3] supports timing definition for all elements in a mixed topology network, but again, accounting for the many different timing paths is a non-trivial process.

Worldview Satellite Imagery Browsing and Downloading ToolTBMG-2217906/01/2015
Worldview is a software tool designed for interactively browsing and downloading imagery from NASA’s Earth observing satellites. Building upon a set of open source mapping and user interface libraries, it provides an environment to visually discover interesting phenomena as observed by NASA satellites, then download the data for further analysis. It was originally designed to address the needs of the near-real-time applications community to provide relevant information for time-critical scenarios such as wildfire and flood management. As such, satellite imagery is available to be viewed in Worldview within four hours of observation; the imagery can be viewed in its highest, or native, resolution, and the imagery can be panned and zoomed rapidly through space and time to find the most relevant/cloud-free information available.
