The invention discloses a vehicle braking control method and device, a computer storage medium and a vehicle. The method comprises the steps that in response to a braking demand instruction, target demand negative torque is obtained; and controlling a three-phase upper bridge arm and/or a three-phase lower bridge arm of the three-phase inverter circuit to be synchronously connected and disconnected according to a preset duty ratio, determining working parameters of the three-phase inverter circuit according to the target demand negative torque, and controlling the driving motor according to the working parameters of the three-phase inverter circuit so as to enable the driving motor to generate the target demand negative torque. According to the method, the working parameters of the three-phase inverter circuit are determined according to the target demand negative torque determined according to the braking demand instruction, so that negative torque control without a position sensor is realized, a driving motor generates the target demand negative torque to enable the vehicle to enter a stop state as soon as possible, and the driving safety is improved.

    本申请公开了一种车辆制动控制方法、控制装置、计算机存储介质及车辆,所述方法包括:响应于制动需求指令,获取目标需求负力矩;按照预设占空比控制三相逆变电路的三相上桥臂同步通断和/或三相下桥臂同步通断,并根据目标需求负力矩确定三相逆变电路的工作参数,根据三相逆变电路的工作参数对驱动电机进行控制,以使驱动电机产生目标需求负力矩。该方法根据制动需求指令确定的目标需求负力矩对三相逆变电路的工作参数进行确定,从而实现无位置传感器下的负力矩控制,以使驱动电机产生目标需求负力矩让车辆尽快进入停止状态,提高驾乘安全性。
