A software hazard analysis method for automotive control system

Safety is one of the key issues of current and future automobile development. Increasing functionality, complexity and software content of automotive embedded system have led to more risks of systematic failures and random hardware failures. Among these risks, a considerable portion is caused by software functional failures. This makes it necessary to perform the hazard analysis at the beginning of the software development process. In this paper, we present a comprehensive software hazard analysis method which applies a number of hazard analysis techniques and the proposed method is applied to software development process for Automated Manual Transmission (AMT) control system. The process of software hazard analysis is described in detail and the analysis results are integrated.
