Modern vehicles are running complex and safety critical applications distributed over several Electronic Control Units (ECUs). Some ECUs are equipped with communication interfaces providing access to other devices, networks or remote services. Since the number of attack vectors is increasing, an early investigation of the impact of attacks becomes steadily more important. This paper gives an example...
Next-generation autonomous and semi-autonomous vehicles will not only precept the environment with their own sensors, but also communicate with other vehicles and surrounding infrastructures for vehicle safety and transportation efficiency. The design, analysis and validation of various vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) applications involve multiple layers, from V2V/V2I...
There are various methodologies that support theextraction of timing models from EAST-ADL design-level modelsduring the development of vehicular embedded software systems. These timing models are used to predict timing behavior ofthe systems by performing end-to-end timing analysis. Thispaper presents a comparative evaluation of three methodologies. We present an evaluation framework that consists...
Estimating the situation awareness of a driver is very important for driving safety support systems. The most frequent type of fatal traffic accident in Japan involves pedestrians' being hit by drivers of “aimless driving” status. In this study, we investigate drivers' gazing behavior for detecting pedestrians. To make subjects think of other things and engage in “aimless driving,” we gave them nonvisual...
The intelligent transportation systems problems of adaptive cruise control and variable timing for traffic intersection signals are explored with emphasis on verification of safety properties.
The main objective of this study is to design and implement a suitable algorithm and its simulation for vehicle detection to control road traffic. The system developed is able to detect moving metal objects (vehicles) and then to calculate the appropriate duration for the traffic signals at an intersection to operate. By employing mathematical functions to calculate the appropriate timing for the...
Allocating software components and messages to computing devices and their interconnecting networks is a great challenge in vehicle control system development. The allocation decisions are usually made at an early development stage without the implementation details of the computing platform. To produce low-cost products with correct vehicle control, the software allocation must facilitate the final...
In this paper we propose to use components for managing the increasing complexity in modern vehicular systems. Compared to other approaches, the distinguishing feature of our work is using and benefiting from components throughout the development process from early design to development and deployment, and an explicit separation of concerns at different levels of granularity. Based on the elaboration...
This paper presents principles and results of dynamic testing of an SRAM-based FPGA using time- resolved fault injection with a pulsed laser. The synchronization setup and experimental procedure are detailed. Fault injection results obtained with a DES crypto-core application implemented on a Xilinx Virtex II are discussed.
Worst case execution time analysis based on measurements requires large test suites to obtain reliable numbers. We are thus developing tools to efficiently generate these test sets in a whitebox-testing approach. To make project progress measurable and guard against regressions, a benchmarking suite is sought for. We present a set of requirements that have been collected and outline the design of...
