The invention discloses a method for controlling a vehicle from braking to braking and a related device, relates to the technical field of vehicle control, aims to solve the problem that the vehicle is easy to pitch and pause in the process from braking to braking, and realizes comfortable braking based on coordination of hydraulic braking control and driving motor torque control. Specifically, in the running process of a vehicle, a system calculates current vehicle parameters, environment parameters and user braking parameters in real time, and in the uphill working condition, on one hand, a driving motor is controlled to output driving torque to offset ramp resistance, and on the other hand, when the torque capacity of the motor is enough, the driving torque is controlled to offset ramp resistance. The pitching and jerking feeling in the braking process can be relieved through a large hydraulic braking pressure coefficient, and the braking comfort is improved. And when the torque capacity of the motor is insufficient, a smaller hydraulic braking pressure coefficient is used for ensuring that the vehicle is braked on the ramp without sliding. Therefore, according to the scheme, on the premise that it is guaranteed that the vehicle cannot slide during uphill braking, the comfort of braking to stop is improved.

    本申请公开了一种车辆制动到刹停的控制方法及相关装置,涉及车辆控制技术领域,为解决车辆在制动到刹停过程中易出现俯仰和顿挫感的问题,该方法基于液压制动控制和驱动电机扭矩控制相协调实现舒适刹停。具体的,车辆在行驶过程中,系统实时计算当前车辆参数、环境参数及用户制动参数,在上坡工况时,一方面控制驱动电机输出驱动扭矩抵消坡道阻力,另一方面在电机扭矩能力足够时,可以使用较大的液压制动压力系数来减缓制动过程中的俯仰和顿挫感,提高制动舒适性。在电机扭矩能力不足时,使用较小的液压制动压力系数来保证车辆在坡道上制动不溜车。可见,该方案在保证上坡制动不会溜车的前提下,提高了制动到停的舒适性。
