摘要
利用技术路线图方法和情景分析方法,通过分析电池和充电设施技术的发展路径以及电动汽车成本下降潜力等影响电动汽车发展的主要制约因素,探寻并提出我国纯电动汽车发展的技术路线图和政策路线图,为政府部门制定电动汽车产业中长期发展战略提供依据。
From the perspective of complete vehicle control,a solution scheme for integrated longitudinal dynamics control is proposed.In respect of function,the control characteristics and their scopes of application of subsystems are linked together,realizing the optimization of overall performance;with regard to hardware,sophisticated sensors,controllers and actuators are integrated,and a modular on-board test platform is developed;as for software,a longitudinal dynamics coordinated controller is put forward based on hierarchical control architecture,and the control strategies of subsystems on bottom layer are fused effectively.Real vehicle tests are conducted and the results show that the integrated control system developed can avoid mutual interference among subsystems,further improving the comprehensive performance of vehicle in longitudinal movement.
