Design of Testbed System for Parallel HEV Powertrain

Testbed is an important tool for control strategies research of hybrid electric vehicle(HEV). The paper presents an dynamic testbed design for single shaft parallel HEV powertrain. The testbed uses an AC dynamometer and the monitoring computer system is developed on LABVIEW virtual instrument platform. The multi-energy management system uses AutoBox, a dSPACE rapid prototyping platform, can make HEV powertrain work under the ECE drive cycles based on MATLAB/Simulink model. ControlDesk, an experiment software, is used to monitor and change control parameters on-line. Many HEV powertrain tests are done and the results show that the testbed system has the ability to research HEV control strategies.
