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 and computer equipment, and relates to the technical field of vehicle control. Under the condition that the brake pedal is triggered, the total required brake torque and the brake pedal opening rate are obtained; when the opening degree of the brake pedal is smaller than a preset opening degree threshold value and the opening degree speed of the brake pedal is smaller than a preset speed threshold value, the brake pedal is started; and according to the comparison result of the first maximum braking torque provided by retarder braking, the second maximum braking torque provided by engine braking, the third maximum braking torque provided by air pressure braking and the total required braking torque, combined braking control is conducted, wherein the first maximum braking torque can be provided by retarder braking, the second maximum braking torque can be provided by engine braking, and the third maximum braking torqu
