Future communication systems for networked traction drives must transfer more data with larger relevance concerning functionality, security and availability. For this after a description of electronic control units and the relevant bus systems (CAN, FlexRay et al.) proposals for the development of networked drive systems were submitted. As an application and based on the research of a prototype passenger car with a parallel hybrid concept a fault-tolerant communication system with two dynamically redundant CAN channels was developed. For validation of the CAN-network and a programmed gearbox ECU a Hardware-in-the-Loop-Simulation was drawn up. Thus function and integration tests could be accomplished and system and component reactions with critical error and failure scenarios could be secured.
