Development of measurement and control system for vehicular powertrain testbench in HEV applications

Vehicular powertrain test bench was designed. A LabVIEW based measurement and control system for the test bench was secondary developed. CAN signals of powertrain´s master controllers, serial signals of electric driving system based on USS and MODBUS protocol were synchronously sampled and monitored. The system integrated various communication protocols in one platform and had a good portability and scalability. This test bench was used in applications of reliability test for hybrid powertrain system with ISG (Integrated Starter/Generator). For electromagnetic coupling power synthesis box, basic performance of key components and dynamic performance on simulated working condition were also tested.
