CAN controlled complex real time stimulus for verification and validation of powertrain systems

Abstract

Today’s requirements for powertrain-engine management systems are increasing in various aspects. Stronger emission standards, faster system response times, increased accuracy/ precision in continuous engine position, the design of next-generation powertrain systems and higher customer expectations etc. demands software verification and validation from the perspective of real-time applications, where timing is a significant concern. The approach of verification and validation as proposed in this paper focus on the complex timing information derived from the sensors, processing of complex signals and driving the power stage ASIC’s via accurate timing e.g. accurate angle at which the fuel must be injected and energizing time, prediction of high resolution, continuous engine position, etc. This paper discloses a method for generation of complex real time stimulus controlled via Controller Area Network (CAN) interface to verify and validate the powertrain systems, thus improving the robustness of the system electronic.
