An Automotive EHPS Software Reliability and Testing

Abstract

The electronic control plays an important role in the modern automotive world. As more software is embedded in the vehicle electronics, software quality and reliability becomes essential to the vehicle reliability. This paper summarizes the embedded software reliability and testing performed at Dare Auto, Inc. for an automotive EHPS (Electro-Hydraulic Power Steering) pump. The ASPICE (Automotive Software Process Improvement and Capability Determination) process has been used during the design and development. The component, subsystem and vehicle level testing have been conducted before releasing for production. The lessons learned and the issues have been identified.
