Abstract

Based on continuous efforts devoted to the clean vehicular technology, ITRI successfully developed the first new-type Dual-Hybrid Electric Vehicle (Dual-HEV) in Taiwan. An innovative system design and advanced control technologies make this dual-HEV as a promising product in the near future. Domestic automakers even international manufacturers show strong intentions to ITRI core technologies. This paper firstly describes the proper system designs of the target vehicle. An electricclutch is applied to properly switch the serial/parallel modes for improving the drivability and fuel economy. Next, the controller schemes, operation modes, and the energy management are also introduced. The control strategies of mode switching, gear shifting, also energy distribution are derived via ECMS (Equivalent Consumption Minimization Strategy) analysis which leads to the minimized energy consumption. Designed system and the advanced vehicle control unit are ultimately integrated. The strategy verification, parameter calibration, and the system modification then can be conducted on the dynamometers and eventually on the road. Based on the test results, a dramatic improvement of fuel economy exceeds 50% compared with the traditional ICE vehicle.
