The invention provides a braking method and system for a hybrid power all-terrain vehicle, and the method comprises the steps: judging whether the current vehicle condition meets the entering condition of an auxiliary braking mode or not, and entering the auxiliary braking mode if the current vehicle condition meets the entering condition; in the auxiliary braking mode, the reverse dragging engine power is determined; the engine throttle opening signal is set to be zero, a reverse dragging rotating speed signal of the generator is determined according to the reverse dragging engine power, and the reverse dragging rotating speed signal is used for the motor controller to drive a driving motor of the vehicle so as to further drive a brake of the vehicle and complete braking operation on the current vehicle. Abrasion of the friction plate of the brake can be effectively reduced, the service life of the friction plate is prolonged, and meanwhile the safety of a whole vehicle during braking can be improved.
本发明提出了一种混合动力全地形车辆的制动方法及系统,方法包括:判断当前车况是否满足辅助制动模式的进入条件,若满足,进入辅助制动模式;在辅助制动模式下,确定反拖发动机功率;将发动机油门开度信号置零,根据反拖发动机功率,确定发电机的反拖转速信号,其中,反拖转速信号用于电机控制器驱动车辆的驱动电机,以进一步驱动车辆的制动器,完成对当前车辆的制动操作。本发明能够有效降低制动器摩擦片的磨损,提高摩擦片的使用寿命,同时能够提高整车制动时的安全性。
