Development of test bed of hybrid electric vehicle based on chassis dynamometer

For verify control strategies in the course of developing hybrid electric vehicle, a kind of test bed was developed. Four removable wheels was used as test best's supporting, all powertrain and control units of true vehicle were contained in the test bed. At the same time, the test bed was connected with two driving wheels. Chassis dynamometer was used to simulate road surface, was connected and fixed with the test bed. For applying different control strategies, dSPACE system was used as real-time control component. Some characteristics tests can be done using the test bed, such as dynamic, economic, discharge and regenerative braking. Test of regenerative braking was done, the test results showed that the test bed can satisfy requirements.
