The invention discloses a downhill vehicle speed control method and system and a vehicle. According to the method, the current rotating speed of a motor and the speed-limiting rotating speed of the motor are subtracted, so that the rotating speed level of the vehicle is determined through the reachable rotating speed difference of the motor, and the reachable rotating speed difference of the motor serves as a unified standard and is compared with a reachable rotating speed difference threshold value of the motor; the problem that judgment standards are difficult to unify due to the fact that the speed-limiting rotating speeds of motors of different vehicles are different is solved; furthermore, the downhill speed of the vehicle is automatically controlled by setting a downhill speed control mode and combining the running state of the vehicle, so that the safety coefficient of the vehicle can be improved, mechanical braking can be reduced, and vehicle loss is reduced.

    本申请公开了一种下坡车速控制方法、系统和车辆,该方法通过对电机当前转速和电机限速转速作差,以实现通过电机可达转速差来确定车辆转速水平,以电机可达转速差为统一标准,与电机可达转速差阈值进行比较,消除了由于不同车辆之间的电机限速转速不同,导致的判断标准难以统一的问题;进一步地,通过设置下坡车速控制模式,再结合车辆的运行状态对车辆的下坡车速进行自动化控制,不仅能提高车辆的安全系数,还能减少机械制动,从而减少车辆损耗。
