A novel solution for an ECU simulator as a key component for automated testing and verification of a vehicle diagnostic device

Abstract

In this paper a generic, configurable solution for an Electronic Control Unit (ECU) simulator is described. The ECU simulator is a component of an Automated Testing System that aims at testing and verifying new devices for vehicle diagnostics. A vehicle has many electronic control units that are communicating over various automotive protocols. The vehicle diagnostic device must be able to communicate with all the ECUs. One of the key components in the automated test system is the ECU simulator that is able to simulate any of the ECUs, communicating with various automotive protocols, simulating any possible state. In this paper, the solution for the challenging task of designing and implementing the ECU simulator is presented.
