The invention relates to the technical field of vehicle control, and discloses a double-motor pure electric heavy truck downhill constant-speed control system which comprises a vehicle control unit, the vehicle control unit is connected with a motor controller, and the motor controller is connected with a middle axle motor and a rear axle motor which serve as downhill constant-speed control actuators. The vehicle control unit is connected with a signal collecting and processing unit and a map positioning device. The invention further discloses a control method of the downhill constant-speed control system for the dual-motor pure electric heavy truck. According to the downhill constant-speed control system and method for the dual-motor pure electric heavy truck, a dual-motor braking mode is adopted, and a retarder does not need to be used.

    本发明涉及车辆控制技术领域,公开了一种双电机纯电重卡下坡恒速控制系统,包括整车控制器,整车控制器连有电机控制器,电机控制器连有作为下坡恒速控制执行器的中桥电机和后桥电机,整车控制器连有信号采集处理单元和地图定位装置。本发明还公开了一种双电机纯电重卡下坡恒速控制系统的控制方法。本发明双电机纯电重卡下坡恒速控制系统及其控制方法,采用双电机制动方式,不需要使用缓速器。
