The invention is suitable for the technical field of vehicle control, and provides a control method, device and equipment for downhill running of an electric vehicle and the electric vehicle. Recognizing an accelerator pedal state, a brake pedal state and a current speed according to a preset road condition recognition condition, and determining whether the current road condition of the electric vehicle is a downhill road condition or not; if it is recognized that the current road condition is the downhill road condition, the target braking force of the electric vehicle is determined according to the current speed of the electric vehicle so as to control the speed of the electric vehicle to be maintained at the target speed. According to the method for judging whether the current road condition is the downhill road condition or not according to the driving state information of the electric vehicle, whether the abrupt slope slow descent function is executed or not in the downhill driving process is determined, and the mode that in the prior art, the abrupt slope slow descent function is achieved by integrating multiple types of sensors is replaced. Therefore, the manufacturing and development cost for realizing the abrupt slope slow descent function is reduced, and the complexity of maintenance and troubleshooting is reduced.
本申请适用于车辆控制技术领域,提供了一种电动车辆下坡行驶的控制方法、装置、设备及电动车辆,该方法包括:获取电动车辆的行驶状态信息;根据预设路况识别条件识别油门踏板状态、制动踏板状态和当前速度,确定电动车辆的当前路况是否为下坡路况;若识别到当前路况为下坡路况,则根据电动车辆的当前速度,确定电动车辆的目标制动力,以控制电动车辆的速度维持在目标速度。通过根据电动车辆的行驶状态信息判断当前路况是否为下坡路况来确定在下坡行驶的过程中是否执行陡坡缓降功能的方法,代替现有技术中通过整合多类传感器实现陡坡缓降功能的方式,从而降低了实现陡坡缓降功能的制造和开发成本、减少了维护和故障排除的复杂性。
