The invention discloses a downhill braking method and device for an electric vehicle and the electric vehicle, and the method comprises the steps: detecting the pedal opening degree of the electric vehicle when the slope value of the environment where the vehicle is located is greater than a preset threshold value; identifying a target braking deceleration of the vehicle according to the pedal opening degree; and collecting the actual vehicle speed and the actual deceleration of the vehicle, and generating a target braking value based on the target braking deceleration, so that the actual deceleration reaches the target braking deceleration through electric braking and/or hydraulic braking. Therefore, the problems that the braking travel and the braking deceleration do not correspond to each other during downhill running of an existing electric automobile, so that the braking expectation of a driver cannot be met, and braking safety risks exist are solved.

    本申请公开了一种电动汽车的下坡制动方法、装置及电动汽车,其中,方法包括:在车辆所处环境的坡度值大于预设阈值时,检测电动汽车的踏板开度;根据踏板开度识别车辆的目标制动减速度;采集车辆的实际车速与实际减速度,并基于目标制动减速度生成目标制动值,以利用电制动和/或液压制动使得实际减速度达到目标制动减速度。由此,解决了目前电动汽车下坡时制动行程和制动减速度不对应,导致无法满足驾驶员的制动预期,存在制动安全风险等等问题。
