以ISG(起动机/发电机一体化)混合动力汽车为对象,对车辆转矩需求、发动机工作区优化和整车控制策略进行了分析,开发了基于MC9S12DP256的整车控制器硬软件系统,并进行了实车试验,实现了发动机起动、纯发动机驱动、混合驱动、驻车充电等多种工作模式,证明了该整车控制器功能设计的合理性和控制策略设计的有效性.%For an ISG (integration of starter and generator) hybrid electric vehicle, the torque demand, the working area optimization and control strategy were analyzed. Based on Mc9S12DP256, the software and hardware system of vehicle controller were developed and verified by the actual experiment. The result shows that various working modes such as the engine starting, engine driving, hybrid driving and battery charging can be realized by using the vehicle controller, which proves the design and control strategy of controller are reasonable and effective.
