The invention relates to a deceleration control device of a vehicle motor. The deceleration control device comprises a transmission separation device, an acceleration detection device, a rotation speed detection device and a control device, due to the fact that the transmission separating device is additionally arranged between the output shaft of the vehicle motor and the wheel output shaft, power output can be cut off under specific conditions. In addition, due to the arrangement of the acceleration detection device and the rotating speed detection device, the speed reduction rate of motor speed reduction and brake disc braking can be calibrated, then the obtained actual speed reduction rate is compared with the calibrated speed reduction rate, the specific speed reduction condition can be obtained, corresponding operation can be executed, and therefore driving safety is enhanced. According to the technical scheme, the specific deceleration condition can be obtained, maintenance can be conveniently carried out after parking, or when the condition occurs, it is indicated that a braking system goes wrong, a driver can be reminded, and dangerous accidents are avoided.

    本申请涉及一种车辆电机的减速控制装置,其包括传动分离装置、加速度检测装置、转速检测装置和控制装置;由于在车辆电机的输出轴和车轮输出轴之间增设有传动分离装置,从而可以在特定情况下切断动力输出;另外由于加速度检测装置和转速检测装置的设置,可以进行标定电机减速和刹车盘制动的减速率,然后将获得的实际的减速率,与标定的减速率进行比较,就可以得出减速的具体情况,以执行相应操作,从而加强行车安全。可以获得具体的减速的情况,便于在停车后获得进行维修,或者当出现上述的情况后表明制动系统出现问题,可以提醒驾驶人员,避免危险事故的发生。
