The invention discloses an unmanned pure electric vehicle whole vehicle energy management system which comprises an unmanned controller, a whole vehicle controller and vehicle information. The unmanned controller comprises an obstacle detection module, a vehicle position detection module, a traffic information module and a vehicle control decision module; the vehicle control decision module calculates a control mode of a vehiclethrough obstacle information acquired by the obstacle detection module, the current real-time position of the vehicle acquired by the vehicle position module, the road state information acquired by the traffic information module, and the acceleration and a braking capability which can be provided by the vehicle within a period of time acquired by the whole vehicle controller; and the whole vehicle controller controls a motor rotation speed demand. According to the mode, based on effective transmission of information of the unmanned controller and the whole vehicle controller, effective fusion of road condition information and vehicle information is achieved, the vehicle driving working condition in a period of time in the future is pre-judged, the vehicle can quickly pass through an intersection, system efficiency of the vehicle system is improved, and the power consumption of the vehicle is reduced.
本发明公开了一种无人驾驶纯电动汽车整车能量管理系统,包括无人驾驶控制器、整车控制器和车辆信息,所述无人驾驶控制器包括障碍物检测模块、车辆位置检测模块、交通信息模块和车辆控制决策模块;所述车辆控制决策模块通过由障碍物检测模块获取的障碍物信息、车辆位置模块获取的车辆当前的实时位置、交通信息模块获取的道路状态信息以及由整车控制器获取的车辆一段时间内所能提供的加速及制动能力,计算出车辆的控制模式,整车控制器控制电机转速需求通过上述方式,本发明基于无人驾驶控制器与整车控制器信息的有效传递,实现路况信息与车辆信息的有效融合,预判未来一段时间内的车辆行驶工况,快速的通过路口,提高车辆系统的系统效率,降低车辆的电耗。
