With the advent of AUTOSAR version 4 and the availability of automotive specific multicore microcontrollers in volume production it is now possible to make very large scale integrations of different v....
This paper investigates what challenges arise when extending the scope of functional safety for road vehicles to also include cooperative systems. Two generic alternatives are presented and compared w....
A new development environment is required where conflict between control systems is minimized, where processing can be executed while maintaining independence between systems, and where quality can be....
ASIL decomposition is a method described in the ISO 26262 standard for the assignment of ASILs to redundant requirements. Although ASIL decomposition appears to have similar intent to the hardware fau....
A safety concept describes a plan for implementing safety. A bad safety concept compromises the achievement of safety or leads to unnecessarily high costs for implementing and proving safety. However,....
Modern development processes put architecture and design models in the center of system engineering activities. With the increasing application of software (SW) controlled functions such development p....
Today's automobiles contain a lot of electrical and electronic (E/E) systems with safety-related functionality. In a design-process compliant to the industrial standard ISO 26262 unknown dependencies ....
Functions such as adaptive cruise control, crash protection systems, active body control and ESP are increasing in complexity and taking an ever more active role in controlling the car. These function....
Two methods are allowed in ISO 26262-5 for hardware analysis of random hardware failures. The 1st method is called “Evaluation of Probabilistic Metric for random Hardware Failures”. The 2nd method is ....
Functional safety of automotive embedded systems is a key issue during the development process. To support the industry, the automotive functional safety standard ISO 26262 has been defined. However, ....
This paper describes an investigation about the efficiency of safety-related non-functional software unit tests (NFSWUT). Well defined design, implementation and test processes are widely used in the ....
The ample electrical power supply makes brake-by-wire technology more suitable for application in electric vehicles than in conventional vehicles. The fail-safe performance of a brake-by-wire system i....
The increased pressure for power, space, and cost reduction in automotive applications together with the availability of high performance, automotive qualified multicore microcontrollers has lead to t....
It is very common that a microcontroller is used in a safety relevant system to acquire data from sensors, process the data and then control actuators. With the shrink of technology every few years it....
New drive concepts as well as advanced driver assistance systems and revised basic functions belong to the main innovation areas in today's automotive industry. Since thereby more and more electric / ....
With the publication of ISO26262 [1] and the concept of Functional Safety, being able to identify the required safety integrity level for software components and defining the respective development st....
Electronic design on detailed hardware level for automotive safety-related systems requires evaluation of the hardware architecture to cope with random hardware failures. The international standard IS....
Due to increasing concerns with petroleum usage and the increasing federal fuel economy regulations, electric powertrains have become more accepted by automotive manufacturers. The lithium-ion batteri....
All functional safety standards have some definition of “risk” and the automotive standard ISO 26262 is no exception. Risk is related to the exposure, the severity of the outcome, and in the case of I....
The paper discusses application of Accelerated Processing Units (APU) in safety analysis and design of safety-critical systems. Specifically, a dependability simulation technique called software fault....
