The invention provides a vehicle braking control method, device and equipment and a storage medium, and the method comprises the steps that under the condition that a vehicle needs to execute braking operation, the current running speed of the vehicle is obtained, and the running speed is compared with a preset speed threshold value; if the running speed is smaller than or equal to the speed threshold value, a hydraulic control mechanism is adopted for conducting braking control on the vehicle; if the running speed is larger than the speed threshold value, the current braking torque, limiting torque and target recycling torque of the vehicle are obtained, and compensation torque currently needed by the vehicle is determined according to the braking torque, the limiting torque and the target recycling torque; if the compensation torque is zero, a motor rotating speed control mechanism is adopted to conduct braking control on the vehicle, and otherwise, the motor rotating speed control mechanism and a hydraulic control mechanism are adopted to conduct braking control on the vehicle together. According to the method, different control modes can be flexibly adopted for executing braking operation according to different vehicle working conditions, and the problems of backing, shaking, too large energy consumption and the like of the vehicle in the braking process are avoided.

    本申请提供一种车辆的制动控制方法、装置、设备及存储介质,方法包括在车辆需要执行制动操作的情况下,获取车辆当前的行驶速度,将行驶速度与预设的速度阈值进行比较;若行驶速度小于等于速度阈值,则采用液压控制机制对车辆进行制动控制;若行驶速度大于速度阈值,则获取车辆当前的制动扭矩、限制扭矩和目标回收扭矩,根据制动扭矩、限制扭矩和目标回收扭矩确定车辆当前所需的补偿扭矩;若补偿扭矩为零,则采用电机转速控制机制对车辆进行制动控制,否则,采用电机转速控制机制和液压控制机制共同对车辆进行制动控制。该方法可以针对不同的车辆工况灵活采用不同的控制方式来执行制动操作,避免车辆在制动过程中产生倒退、抖动、能耗过大等问题。
