Real-time simulation tools are commonly used for designing and testing of automotive embedded control systems. In addition, the Hardware-In-the-Loop (HIL) technique enables previous verification and validation of control strategy avoiding an expensive and time-consuming field test. For this reason, this paper shows a HIL platform for designing and testing of Electrical Power Assisted Steering Systems...
An automotive network needs to accumulate as much data as possible during motion to function in real-time, so that the system can respond to external influences accordingly. All kinds of situations regarding the state of the vehicle and its surroundings must be taken into account. To realize such a scenario many sensors, cameras and further input/output devices are essential to gather the required...
For many cyber-physical systems, there is a strong trend towards open systems, which can be extended during operation by instantly adding functionalities on demand. We discuss this trend in the context of automotive and medical systems. The goal of this paper is to elaborate the research challenges of new platforms for such open systems. A main problem is that such CPS apps shall be able to access...

This paper provides an overview of in-vehicle communication networks and addresses the challenges of providing reliability in automotive Ethernet in particular.
This paper introduces the design of an operating system based on AUTOSAR [Automotive Open System Architecture] for MPC5668G. Embedded system applications are widely used today in aerospace, automotive areas. After the intervention of application specific operating systems, specialized real time operating systems called Vehicular Application Specific Embedded Operating Systems (VASOS) are developed...
The great raise in the number of Electronic Control Units (ECUs) transmitting video flows (cameras) and networking vehicular technologies has caused a raised amount of exchanged video data on in-car network. Besides, the real-time audio and video based driver assistance systems have increased swiftly. These developments have imposed new requisites in terms of data rates, efficiency, performance, capacity,...
In this paper, we consider scenarios, requirements, and architectures for future connected vehicles. Regarding scenarios, we discuss new features like autonomous driving, which have very strong requirements on sensor data fusion, real-time processing, and the complexity of the decision making process. We also address a major trend in automotive architectures, which is the aggregation of computing...
Dataflow software architectures are prevalent in prototypes of advanced automotive systems, for both driver-assisted and autonomous driving. Safety constraints of these systems necessitate real-time performance guarantees. Automotive prototypes often ensure such constraints through over-provisioning and dedicated hardware; however, a commercially viable system must utilize as few low-cost multicore...
The Ethernet-based diagnosis protocol is widely used in automotive systems. Diagnostic gateways have been developed for seamlessly interconnect with Ethernet based diagnostic protocols and traditional in-vehicle network protocols, such as local interconnect network (LIN), controller area network (CAN), FlexRay. A diagnostic gateway is connected to the Internet and manages the interconnection between...
Automotive electronics is a rapidly expanding area with an increasing number of driver assistance and infotainment devices becoming standard in new vehicles. A review of current networking standards within vehicles reveals a fragmented and proprietary situation with several standards such as MOST, CAN and LVDS dominating, all of which are currently being used by various vehicle manufacturers. Due...
During the last years, Ethernet increasingly became the most extensively used local area networking (LAN) technology. It became also attractive for several other fields of application like industry, avionics, automotive and telecommunication. The prolonged application of this technology is principally due to its considerable assets like reduced cost, expandability and flexibility. However, Ethernet...
The E/E (Electrical/Electronic) Architecture is the key enabler for new innovative user functions in the automotive domain. The E/E Architecture needs to manage the complexity of the E/E System in a cost-efficient manner. This is a fact for all domains developing mass-produced distributed systems containing embedded software. However, many companies in these domains are missing a clear description...
The road capacity can be increased when utilizing the real-time traffic information uploaded by the floating cars. In symmetrical two-route scenario, the influence of the percentage of floating cars (Pflt) on the performance of MVFS and CCFS is analyzed. Simulation results show that Pflt has little influence on the performance of MVFS, while has great influence on the performance of CCFS. The performance...
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...
In this paper we discuss the need of a novel control architecture for managing the growing complexity in modern vehicles and outline a multi-layered approach for self-management in adaptive automotive systems.
