The invention discloses an abrupt slope slow descent system with an electromagnetic brake, an electric vehicle and an abrupt slope slow descent method. The system comprises an accelerator, a controller, a driving motor, the electromagnetic brake, a power source and an abrupt slope slow descent switch. And the accelerator is connected with the controller. The power supply is respectively connected with the controller and the electromagnetic brake; and the abrupt slope slow descending switch is arranged between the power supply and the electromagnetic brake. The controller is connected with the driving motor and the electromagnetic brake, and the driving motor is connected with the electromagnetic brake. The controller is provided with a reversing signal port, the power source is further connected with the reversing signal port, and the reversing signal port is used for sending a negative electric signal to the controller. The abrupt slope slow descent switch is used for controlling the power source to supply power to the reversing signal port and the electromagnetic brake port. During downhill, the abrupt slope slow descent switch is closed, the electromagnetic brake is opened, and the vehicle is switched to a reverse gear. Due to gravity, wheel rotation power generation and upward braking force generated by reverse rotation of the driving motor, the vehicle slowly descends, vehicle parts are prevented from being damaged due to sudden stop, and the safety of the vehicle is also improved.
一种带电磁刹车的陡坡缓降系统、电动车辆以及陡坡缓降方法,包括:加速器、控制器、驱动电机、电磁刹车、电源和陡坡缓降开关。加速器和控制器连接。电源分别和控制器以及电磁刹车连接,电源和电磁刹车之间设置陡坡缓降开关。控制器和驱动电机以及电磁刹车连接,驱动电机和电磁刹车连接。控制器上设置倒车信号端口,电源还和倒车信号端口连接,倒车信号端口用于向控制器发出负电信号。陡坡缓降开关用于分别控制电源向倒车信号端口和电磁刹车端口供电的电流导通。下坡时闭合陡坡缓降开关,电磁刹车打开,车辆切为倒车档。由于重力,轮子旋转发电,驱动电机反向转产生向上制动力,车辆缓慢下降,避免急停损坏车辆部件,车辆的安全性也得到提升。
