A tandem type hybrid power mining dump truck control system comprises a range extender and a control unit RCU of the range extender, and the range extender is a combination of an engine and a generator. The range extender generates electricity according to the power requirement given by the VCU, provides electric energy for an electric load on the vehicle and charges a power battery; when the whole vehicle is electrically braked, the output electric power of the driving motor exceeds the charging power of the power battery or the battery is fully charged, the generator is used as a motor, and electric energy is consumed in an engine cylinder braking mode. Under the condition that the requirements of vehicle traction and braking are met, frequent speed regulation and start-stop of an engine are not carried out as far as possible, and unit oil consumption is increased due to frequent start-stop and speed regulation of the engine; through the control strategy, frequent speed regulation of the range extender is reduced, and the fuel economy of the hybrid power mining dump truck is improved. The electric braking power of the whole vehicle during heavy-load downhill is improved, the dependence on mechanical braking is reduced, the loss of mechanical braking parts is reduced, and the safety of the vehicle during heavy-load downhill is improved.

    一种串联式混合动力矿用自卸车控制系统,包括增程器及其控制单元RCU,所述增程器为发动机与发电机的组合;增程器根据整车控制器VCU给定的功率需求发电,给车上用电负载提供电能,并为动力电池充电;整车进行电制动时,驱动电机输出电功率超过动力电池充电功率或者电池满电时,发电机作电机使用,通过发动机缸内制动方式消耗电能。满足车辆牵引、制动的需求下,发动机尽可能不进行频繁调速、启停,发动机频繁启停、调速会导致单位油耗增加;本发明通过控制策略,减少增程器频繁调速,提高混合动力矿用自卸车燃油经济性。提高重载下坡时整车电制动功率,减少对机械制动的依赖,减少机械制动部件损耗,提升车辆重载下坡的安全性。
