The invention provides an auxiliary braking control method, an auxiliary braking control system and a vehicle. The auxiliary braking control method comprises the steps that if it is recognized that the opening degree of an accelerator pedal of a vehicle is 0 and the opening degree of a brake pedal of the vehicle is 0, deceleration information and current vehicle speed information of the vehicle are obtained, and whether the vehicle braking behavior meets the vehicle braking requirement or not is determined according to the deceleration information and the current vehicle speed information; and according to the condition whether the vehicle braking behavior meets the vehicle braking requirement or not and the condition whether a power battery of the vehicle is overcharged or not, the working state of a range extender of the vehicle and the recycling power generation power of a driving motor of the vehicle are controlled, so that the vehicle is controlled to be braked in the corresponding braking mode. The range extender and the driving motor can be controlled according to the vehicle braking behavior and the charging condition of the power battery in the vehicle sliding process, the optimized braking function is achieved, the economical efficiency of the vehicle is improved, and the service life of a mechanical braking system is prolonged.

    本申请提供一种辅助制动控制方法、辅助制动控制系统和车辆。辅助制动控制方法包括:若识别到车辆的油门踏板开度为0且车辆的制动踏板开度为0,获取车辆的减速度信息和当前车速信息,根据减速度信息及当前车速信息,确定车辆制动行为是否满足车辆制动要求,及根据车辆制动行为是否满足车辆制动要求的情况和车辆的动力电池是否过充的情况,控制车辆的增程器的工作状态和车辆的驱动电机的回收发电功率,以控制车辆在相应的制动模式下制动。本申请可以在车辆滑动的过程中根据车辆制动行为和动力电池的充电情况来控制增程器和驱动电机,实现优化的制动功能,提升车辆的经济性以及机械刹车系统的使用寿命。
