The invention relates to a braking control method and device of a vehicle, the vehicle and a storage medium, a vehicle control unit of the vehicle communicates with an automatic driving module through a first communication bus, and the vehicle control unit communicates with a hydraulic braking system through a second communication bus. Comprising the steps of receiving a braking demand sent by an automatic driving module through a first communication bus; determining a target brake pressure value based on the brake demand, sending the target brake pressure value to the hydraulic brake system through the second communication bus, and calculating a current brake pressure value of the vehicle after the hydraulic brake system executes a brake action based on the target brake pressure value; and if the current brake pressure value is not equal to the target brake pressure value, the hydraulic brake system is controlled to execute the pressure increasing action or the pressure reducing action according to the target brake pressure value and the current brake pressure value till the current brake pressure value is equal to the target brake pressure value. Therefore, the complexity of the vehicle control system is simplified, the reliability of the system is improved, and the occupied space is greatly reduced.
本申请涉及一种车辆的制动控制方法、装置、车辆及存储介质,车辆的整车控制器和自动驾驶模块通过第一通信总线进行通信,整车控制器和液压制动系统通过第二通信总线进行通信,包括:接收自动驾驶模块通过第一通信总线发送的制动需求;基于制动需求确定目标制动压力值,并通过第二通信总线发送目标制动压力值至液压制动系统,并在液压制动系统基于目标制动压力值执行制动动作后,计算车辆的当前制动压力值;若当前制动压力和目标制动压力值不相等,则根据目标制动压力值和当前制动压力值控制液压制动系统执行增压动作或减压动作,直至当前制动压力值等于目标制动压力值。由此,简化了车辆控制系统的复杂度,提高了系统可靠性,大幅缩小占用空间。
