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.
