ZF builds ‘middleware’ to address vehicle software escalation21AUTP03_0901/27/2025
Acknowledging the emergence of the “software-defined” vehicle, ZF announced that it is in the process of developing a “middleware” platform designed to facilitate communication between a typical new vehicle's ballooning number of software-controlled components and systems. Company engineers and executives said the first vehicles leveraging the new middleware will be on the road in 2024, but the platform is being created because the industry has to grasp “what the car will look like in the 2030s,” said Dirk Walliser, senior VP - corporate R&D, Innovation & Technology for ZF Friedrichshafen AG. Coinciding with the undertaking to create its middleware platform, ZF also announced it is establishing a Global Software Center to, according to a release, prepare for “new challenges in the triad of software, functions and smart systems” and to proactively pursue “numerous development processes.” Opening in 2021, the Global Software Center will be headed by Nico Hartmann, VP, Software Solutions

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

Event-triggered Adaptive Robust Control for Lateral Stability of Steer-by-wire Vehicles with Abrupt Nonlinear Faults2022-01-111203/29/2022
Owing to the fact that autonomous vehicles equipped with active front steering (AFS) have the features of time-varying, uncertainties, high rate of fault and high burden on the in-vehicle networks, this article studies the adaptive robust control problem for improving steer-by-wire (SBW) vehicles lateral stability in the presence of abrupt nonlinear faults. Firstly, a robust H∞ controller, as an upper-level controller, is designed to obtain the corrected steering angle for driving both the yaw rate and the sideslip angle to achieve their desired values. Takagi-Sugeno (T-S) fuzzy modeling approach which has shown the extraordinary ability in coping with the issue of nonlinear is applied to deal with the challenge of the changing longitudinal velocity. The output of upper controller can be calculated by parallel-distribute-compensation (PDC) scheme. Then, an event triggered adaptive fault tolerant lower controller is proposed to track the desired front wheel steering angle offered by the

Future of Automotive Embedded Hardware Trust Anchors2022-01-013403/29/2022
The current automotive electronic and electrical (EE) architecture has reached its scalability limit and in order to adapt to the new and upcoming requirements, novel automotive EE architectures are currently being investigated to support: a) the Ethernet backbone, b) consolidation of hardware capabilities leading to a centralized architecture from an existing distributed architecture, c) optimization of wiring to reduce cost, and d) adaptation of service-oriented architectures. These requirements lead to the development of Zonal EE architectures that require appropriate adaptation of used security mechanisms and the corresponding utilized trust anchors. And while current architecture (ECU internal and in-vehicle networking) approaches are being pushed to their limits, simultaneously, the current embedded security solutions also seem to reveal their limitations due to an increase in connectivity.

EXPLORATION OF THE REAL TIME BEHAVIOR OF EVENT CHAINS BY SIMULATION AND MEASUREMENT OF "IN VEHICLE NETWORKS"2021-26-049009/22/2021
Recent years, transformation in automotive industry have a huge technology growth. Flexray, Control Area Network (CAN), Local Interconnect Network (LIN), CAN-FD, Automotive Ethernet are the principal automotive communication protocols in industry exercise. CAN protocol is primely used among the automotive communication protocols. But such predominantly used CAN protocol doesn‘t have clear appropriateness of overhead, latency and deterministic performance behavior. In order to analyze these complex uncertainty behavior, Electronic Control Unit’s (ECU) dynamic architecture of communication system and the CAN bus load behavior should be identified. Here, we used AUTOSAR based communication stack. This abstract deals with deterministic timing analysis of CAN protocol by which we can optimize it for having potential End-to-End (E2E) runtime communication for a dedicated event chain. The analysis was targeted by two approaches – (a) Timing Simulation and (b) prove of simulation results

Research in OFDM-Based High-Speed In-Vehicle Network Connectivity for Cameras and Displays2021-01-015104/06/2021
Growing trends of connected and autonomous vehicles have pushed for increased resolutions of cameras to 8Mpix and displays to 4K/8K, leading to requirements for high-speed interfaces that support 10Gbps and beyond. Unlike data center or enterprise networks which normally operates under controlled indoor environments, in-vehicle networks are required to operate in harsh temperature and interference environments. Due to cost restrictions, the use of single pair wire is prevalent for in-vehicle networks. In general, as data transmission speed increase, signal spectrum spreads across greater frequency range. Since insertion loss of a channel increases in proportion to signal frequency, it becomes more difficult to secure SNR (signal-to-noise ratio) margins as bit rate increases. This makes it increasingly difficult for a device (e.g. ECUs, sensors, and displays) with high-speed communication interface to meet EMC (electromagnetic compatibility) criteria imposed by automotive OEMs. If this

State of the art survey on comparison of CAN, Flexray, LIN Protocol and Simulation of LIN protocol2020-01-129304/14/2020
Controller area network (CAN), FlexRay and local interconnect network (LIN) digital protocols are commonly used for communication in modern vehicles. A modern vehicle contains up to 70 electronic control units. This paper is about the literature review of these protocols. We also implement these three protocols. The communication cycle, process, message structure, and hardware elements are discussed for all three protocols. Performance is measured in terms of reliability and latency. In addition, a comparison between the CAN, flexRay and LIN protocols is made. Experimental results indicate that CAN protocol has advantage when it comes to real-time priority based communication. However, if all the events have equal priority, then FlexRay works well, LIN prtocol is budget friendly and has lowest cost in all 3 protocols but at the same time it is unreliable.

Hypervisor Implementation in Vehicle Networks2020-01-133404/14/2020
As technology has grown in complexity, so have the use cases and applications. In particular, vehicle systems have evolved from the mechanically simple tool with the singular utility of transport to a transportation device embedded with computer systems, allowing for the vastly superior UX. As the technological advances and increased vehicular functionality, this has also increased the number of vulnerabilities and opportunity for a successful system breach. Any of these within the present architecture, when successfully exploited, may lead to a cascade of failures, or a limited number of critical failures. To mitigate this opportunity for the attackers, one non-obtrusive measure involves a method used in non-vehicle systems. The hypervisor implementation is recommended to assist with this mitigation. While this has not been researched at length in the present use case, the application of this well-versed tool is viable. The hypervisor offers many benefits to the vehicle architecture

Planning to find a solution to collect the data from various vehicular devices about the information related to the pollution becomes a cumbersome job. The need of the data, under what time duration data has to be transmitted, how they are interconnected and whether data needs to be stored or how they are processed is a major question that arise when dealing with collecting data and internetworking with various vehicular devices. A study of two different types of approaches for internetworking between the devices is discussed. One related to real time setup of mobile application and other with the dynamic cluster approach when the nodes are moving in a region was considered.

Vulnerability of FlexRay and Countermeasures11-02-01-000205/23/2019
The importance of in-vehicle network security has increased with an increase in automated and connected vehicles. Hence, many attacks and countermeasures have been proposed to secure the controller area network (CAN), which is an existent in-vehicle network protocol. At the same time, new protocols-such as FlexRay and Ethernet-which are faster and more reliable than CAN have also been proposed. European OEMs have adopted FlexRay as a control network that can perform the fundamental functions of a vehicle. However, there are few studies regarding FlexRay security. In particular, studies on attacks against FlexRay are limited to theoretical studies or simulation-based experiments. Hence, the vulnerability of FlexRay is unclear. Understanding this vulnerability is necessary for the application of countermeasures and improving the security of future vehicles.In this article, we highlight the vulnerability of FlexRay found in the experiments conducted on a real FlexRay network.

A GPU Accelerated Particle Filter Based Localization Using 3D Evidential Voxel Maps2019-01-049104/02/2019
An evidential theory is widely used for 2D grid-based localization in a robotics field because the theory has benefits to consider additional states such as 'unknown' and 'conflict'. However, there are some problems such as computational limitation and excessive resource share when the localization system is expanded from 2D grid to 3D voxel. In order to overcome the problems, this paper proposes the parallelized particle filter based localization system using 3D evidential voxel maps. A many-core processor based parallel computing framework with optimization techniques is applied to accelerate the computing power. Experiments were performed to evaluate the performance of the localization system in a complex environment, and to compare the computational time and resources between various types of processing units. The experimental results show that the proposed parallel particle filter is much more efficient than particle filter without parallel computing regarding computational cost.

Securing the Secret Key2019-01-009701/16/2019
Recent advances in automotive technologies have paved way to a new era of connectivity. Advanced Driver Assistance Systems are getting deployed in automobiles; many companies are developing driverless cars; connected cars are no more a work of mere research. [1] Vehicle manufacturers are developing ways to interface mobile devices with vehicles. However, all these advances in technology has introduced security risks. Unlike traditional computing systems, the security risk of an automobile can be fatal and can result in loss of lives [2]. The in-vehicle network of an automobile was originally designed to operate in a closed environment and hence network security was not considered during its design [3]. Several studies have already shown that an in-vehicle network can be easily compromised and an intruder can take full control of the vehicle. Researchers are working on various ways to solve this problem. Securing the in-vehicle communication by encrypting the messages is one such way

CAN FD: The Easy Path to Faster Communication Speed2018-01-502206/27/2018
The amount of data communicated in automotive networks is increasing rapidly, leading to more complex systems alongside the rising number of Electronic Control Units (ECUs) in modern vehicles. As the number of ECUs has risen, Controller Area Network (CAN) communication bandwidth has been pushed to its limit. Existing solutions - such as using multiple CAN buses, sending multiple CAN frames or switching to another protocol - require a significant system-design effort and replacement of hardware and software. This has paved the way for CAN Flexible Data-rate (CAN FD), which extends the CAN standard and permits significantly higher data rates, enabling faster firmware upgrades. However, some changes must be made like: exchange the classical CAN microcontroller with a CAN FD microcontroller and also a CAN FD transceiver must be used. This article will explore the benefits of CAN FD, how it compares with the classical CAN protocol, requirements for systems and how to introduce CAN FD into
