In modern vehicles the architecture of electronics is growing more and more complex because both the number of electronic functions – e.g. implemented as software modules – as well as the level of networking between electronic control units (ECUs) is steadily increasing. This complexity leads to greater propagation of failure symptoms, and diagnosing the causes of failure becomes a new challenge.
This paper describes a method for verifying and testing the diagnosis algorithms by means of a PC-based simulation. A model of the system is simulated with failures such as faulty signal values. Setting up such a simulation on a PC – instead of waiting for the production hardware – enables each function and diagnostics developer to verify their implementations earlier and more easily.
