The invention discloses a vehicle auxiliary braking device and a vehicle, the vehicle auxiliary braking device adopts a clutch, a motor and an auxiliary braking controller, the clutch is respectively connected with the motor and a transfer case, and the auxiliary braking controller is respectively connected with the motor, a power controller of a mechanical driving unit and a signal detection port; and the controller is used for identifying the braking intention of a driver according to the vehicle state, the vehicle speed, the brake pedal displacement opening degree, the brake pedal speed and the accelerator pedal displacement information detected by the power controller and the signal detection port, judging a braking scene or a braking mode, and then controlling the motor to act and starting a corresponding auxiliary braking strategy. The existing brake system does not need to be modified, and the performance of the original brake system is not influenced; auxiliary braking can be provided for different scenes, the whole vehicle braking smoothness is improved, the maximum braking force and braking safety are increased, and the service life of a mechanical braking system is prolonged.

    本发明公开了一种车辆辅助制动装置及车辆,车辆辅助制动装置采用离合器、电机和辅助制动控制器,离合器分别与电机和分动器相连接,辅助制动控制器分别与电机、机械驱动单元的动力控制器和信号检测口相连接,用于根据动力控制器和信号检测口检测到的车辆状态、车速、制动踏板位移开度、制动踏板速率和加速踏板位移信息,对驾驶员的制动意图进行识别,判断制动场景或制动模式,进而控制电机动作,启动相应的辅助制动策略。本发明无需对已有制动系统进行改装,不影响原有制动系统的性能;可以针对不同场景提供辅助制动,提高整车制动平顺性、增大最大制动力、制动安全性和延长机械制动系统的寿命。
