Chassis dynamometer for hybrid electric vehicle based on controller area network

The development of chassis dynamometer of hybrid vehicle based on CAN bus was studied. Chassis dynamometer of hybrid vehicle measurement methods and loading devices are analyzed, and laid the foundation for the resistance simulation of chassis dynamometer. Road resistance simulation on HEV chassis dynamometer is researched, getting electric quantity simulation type of chassis dynamometer driving resistance. The research and development of hybrid vehicle chassis dynamometer based on CAN Bus is conducive to enhance the level of whole hybrid vehicle and car assembly, establish the test procedures, test methods and test standards, provide a research platform and methods for test evaluation of HEV energy utilization.
