This paper presents some need to implement the evaluation of reliability due to network communications in automotive environments. Modern vehicles consist of many components and electronic control units (ECUs) which are interconnected for performance and safety. Each of the components is difficult to evaluate in connection to the In-Vehicle Communication Networks. Network communication parameters at some later stage may lead to problems such as additional reprogramming effort, waste of resources and significant project delays. Therefore, the timely testing of the Multi-domain communication stability is vital for safeguarding a smooth development process. Functional safety is an integrated part of the overall safety requirements for a product and is concerned with assuring that a system or equipment item operates correctly; taking into account the safe management of likely operator errors, system failures and environmentally induced problems. The behavior of the monitor is assessed and the results show that it is feasible to monitor and verify functional safety properties, as defined by the ISO 26262 standard for functional safety in road vehicles, using the proposed method. In order to improve functional safety, fault injection is a fundamental step for testing network behavior and shall be done prior to the application development. It is possible to verify the reliability and efficiency of the Multi-domain communication for a given system topology by injecting reproducible disturbances. And, it offers advantages in flexibility and cost over adding specialized fault injecting network nodes that tested of a vehicle system with respect to transient communication network faults. It was monitored through the implemented system by injecting faults into the networks. The resistor and capacitor for analog disturbance pulses may be caused by short circuits, poor contacts in a real network. And we could simulate for generation of fault injection mechanisms and for running injection experiments. © 2016 The Authors. Published by European Science publishing Ltd.
