This paper addresses requirements from future automotive electronics system concept/design to computing technology or platform filling processing characteristics which will be used in applications of automated driving generation. We cannot completely predict future trends of functionality or application, so it is important to have flexible and scalable computing platform for that generation. The platform...
This paper addresses requirements from future automotive electronics system concept/design to computing technology or platform filling processing characteristics which will be used in applications of automated driving generation.

This document describes the motivation, theoretical description, development, and flight test of a system that utilizes unmanned air vehicles (UAVs) and unattended ground sensors (UGSs) to detect and image intruders on a road network. The need for completely autonomous behavior drives the design of this system so that the UAV makes onboard decisions based upon inputs from off-board sensors (unattended...
The following document describes the way Mobile ELM works and what is its real life applicability in mobile equipment industry. The solution presented by us has the main advantage that it can use Bluetooth communication in order to create a communication channel between software that monitors hardware components, and our application that signals every undesirable behavior. In this way in the future...
In 2010, over 20.3 million vehicles were recalled. Software issues related to automotive controls such as to cruise control, anti-lock braking system, traction control and stability control, account for an increasingly large percentage of the overall vehicles recalled. We have developed AutoPlug, an automotive Electronic Controller Unit (ECU) test-bed to diagnose, test, validate and verify controls...
The potential of applying search-based testing principles to functional testing has been demonstrated in various cases. The focus was mainly on simulating the system under test using a model or compiled source code in order to evaluate test cases. However, in many cases only the final hardware unit is available for testing. This research presents an approach in which evolutionary functional testing...
The information from bus sensors is not able to perform on the in-vehicle meter directly because original information is not compatible with transmitting. To overcome this challenge, the authors designed a meter information module (MIM), whose fundamentals were collecting, processing and sending signals. The MIM chose Freescale's HCS12 Microcontroller Unit (MCU) as its core component and Controller...
The embedded wireless application for vehicle diagnosis is presented. The design uses an ATmega16 microcontroller as a master which controls the wireless RF transceiver module nRF905 to realize the wireless vehicle diagnosis function. The nRF905 module is used for signal transmission between diagnostic-tester and vehicle ECU. Diagnosis application software is also developed on the PC Windows platform...
This paper presents a remote vehicle diagnosis system that not only be used in vehicle diagnosis and maintenance, but also performs well in the vehicle development and enterprise management. As diversities of physical layer and data link layer protocols are widely used in the automotive electrical systems, a general protocol electrical level transfer circuit is designed and solidified software for...
The fast growth of complexity of modern cars, motorbikes and commercial vehicles continues. Although the number of applied Electronic Control Units (ECUs) decreases, they have to fulfill more and more functions concerning performance, comfort and safety. The electric and electronic architecture (EEA) of a vehicle forms the basis for those features and functionalities. An elaborated and evaluated EEA...
With the rapid growth of automotive electronics, the application requirements increase greatly, the hardware abounds continuously, as a result, software system becomes more and more complex. For this reason, some major OEMs found Automotive Open System Architecture (AUTOSAR), now including a large number of automotive, electronics, semiconductor and software companies. AUTOSAR's objectives are to...
With ARM7 as the core, the new intelligent mobile vehicle checking system integrated a lot of hardware modules such as video capture, GPS positioning and wireless transmission, the design of the system software used the embedded software developing platform based on ADS integrated development environment. By the hardware/software co-design, the new intelligent mobile vehicle checking system implemented...
In an overview paper called State of the Art: Embedding Security in Vehicles, Wolf et al. give a general state-of- the-art overview of IT security in vehicles and describe core security technologies and relevant security mechanisms. In this paper we show that a formal analysis of many of the related properties is possible. This indicates that many expected aspects in the design of vehicular security...
In the design of modern vehicles, CAN-bus network has been applied for the information exchange among the ECUs of the vehicle. The CAN communication network for vehicle management system (VMS) is designed based on XC164CS microcontroller in the paper. The characteristics and construction of Twin CAN module of XC164CS were introduced. The principle of time triggered controller area network (TTCAN)...
Communication plays an important role in modern automotive system architecture. In order to optimize the AUTOSAR intra-ECU communication, an approach based on mapping runnable entities is proposed to reduce task switching, and avoid communication data inconsistency and time delay. Taking into account the various communication behaviors of all runnable entities in the current ECU, we provide six extended...
Electronic Control Units (ECUs) are widely used to improve the comfort and reliability of vehicles. It has become the fundamental building block of any automotive subsystem and is interfaced with electro mechanics counterpart. To meet the system wide requirements, these ECUs are interconnected using the communication infrastructure. Although the communication infrastructure in terms of, predominantly,...
Modern automotive subsystems are no longer a heap of electro-mechanics but instead involve a number of electronic control units (ECUs). Electronic control unit (ECU) has become the fundamental building block of any automotive subsystem and is interfaced with electro mechanics counterpart. To meet the system wide requirements, these ECUs are interconnected using the communication infrastructure. Although...
The performance of ESC system is greatly influenced by vehicle design factor and tire performance. But many car maker develop the vehicle can have variability to meet the variety consumer requirement of several countries. ESC system also should be developed with considering the chassis configuration of vehicle and being satisfied the requirement. So, robust control algorithm and value-added-function...
The amount of electronics in vehicles is growing quickly, thus systems are becoming increasingly complex which makes the engineering of these software intensive systems more and more difficult. In the automotive industry the use of product line architectures enables a set of vehicles to share architecture to decrease cost and increase quality. In this study we investigate key issues related to real-world...
