The invention discloses a brake control method, a brake control device, a vehicle and a readable storage medium. The method comprises the steps that under the condition that a braking intention is detected, a target braking strategy is determined in a torque control strategy and a rotating speed control strategy based on the current rotating speed of a motor of the vehicle, the torque control strategy is used for conducting torque control over the vehicle, and the rotating speed control strategy is used for conducting rotating speed control over the vehicle; and controlling the vehicle to run based on the target braking strategy to reduce the speed of the vehicle until the vehicle is completely static. For example, under the condition that the rotating speed is large, the target braking strategy is determined as the torque control strategy, so that the energy recovery efficiency in the vehicle deceleration process is improved. And under the condition that the rotating speed is small, the target braking strategy is determined as the rotating speed control strategy so as to ensure that the vehicle can be accurately stopped. Thus, the advantages of torque control and rotating speed control can be combined in the braking process, so that the energy recovery efficiency in the braking process can be improved, and it is ensured that the vehicle can be accurately parked at the target position.

    本申请公开一种制动控制方法、制动控制装置、车辆和可读存储介质。方法包括在检测到制动意图的情况下,基于车辆的电机的当前转速在扭矩控制策略及转速控制策略中确定目标制动策略,扭矩控制策略用于对车辆进行扭矩控制,转速控制策略用于对车辆进行转速控制;基于目标制动策略控制车辆运行,以降低车辆的速度,直至车辆完全静止。例如,在转速较大的情况下,确定目标制动策略为扭矩控制策略,以提高车辆减速过程中的能量回收效率。在转速较小的情况下,确定目标制动策略为转速控制策略,以确保车辆可精准地停靠。如此,制动过程可结合扭矩控制和转速控制的优势,从而使得可提高制动过程中的能量回收效率,并确保车辆能够精准地停靠在目标位置。
