The invention discloses a vehicle downhill speed limit control method, a vehicle and a computer storage medium, wherein the method comprises the steps: detecting vehicle driving information; judging whether the vehicle is in a downhill road condition according to the vehicle driving information; and if the vehicle is in a downhill road condition, starting a downhill automatic speed limiting control mode, controlling the driving motor to output reverse torque, and enabling the reverse torque to be gradually increased, so as to limit the vehicle speed to be the preset vehicle speed. By means of the method, the safety of downhill driving of the vehicle can be guaranteed, the phenomena that the speed is unstable during downhill, the vehicle pauses and suddenly stops and braking cannot be conducted in time due to the fact that a driver is panic in mind under the emergency condition are avoided through automatic speed limiting processing, and the possibility of vehicle accidents is reduced.

    本发明公开了一种车辆下坡限速控制方法及车辆和计算机存储介质,其中,方法包括:检测车辆行驶信息;根据车辆行驶信息判断车辆是否处于下坡路况;如果是,启动下坡自动限速控制模式,控制驱动电机输出反向力矩且反向力矩逐渐增大,以限制车速在预设车速。该方法可以保障车辆下坡行驶的安全,通过自动限速处理避免了下坡时速度不稳定,车辆出现顿挫和骤停现象以及在紧急情况下由于驾驶员心里恐慌而不能及时刹车的现象,降低了发生车辆事故的可能性。
