Commercial vehicle combined braking control method and device, computer equipment and storage medium

The invention relates to a combined braking control method and device for a commercial vehicle, computer equipment and a storage medium, and relates to the technical field of vehicles. As the opening degree of the brake pedal is smaller than the preset opening degree threshold value and the opening degree speed of the brake pedal is smaller than the preset speed threshold value, it can be indicated that the commercial vehicle is in a long slope descending scene or in other continuous small-intensity braking scenes; and a proper braking mode is selected for braking, so that the braking is relatively flexible. In addition, combined braking control is carried out through multiple braking modes, the service life of braking equipment can be effectively prolonged, heat fade of the braking equipment is reduced, and the reliability and safety of a braking system are improved. 本申请涉及一种商用车联合制动控制方法、装置、计算机设备及存储介质，涉及车辆技术领域。由于制动踏板开度小于预设开度阈值且制动踏板开度速率小于预设速率阈值可以表示商业车处于下长坡的场景或者处于其它持续小强度制动的场景，在上述场景下，可以根据发动机制动和电机制动的可用情况，选择合适的制动方式
