The invention discloses a control method and device of an electric composite braking system, a storage medium and a commercial vehicle, and can be applied to the technical field of vehicles. According to the method, the required braking deceleration is determined according to the braking signal at the current moment, and the required braking torque is determined according to the vehicle state data and the required braking deceleration at the current moment, so that the timeliness of the data is improved; the target motor braking torque of the vehicle is determined according to the rear axle demand braking torque and the maximum motor braking torque, the working state of a motor is controlled according to the target motor braking torque, and meanwhile the target braking pressure of the vehicle is determined according to the front axle demand braking torque, the rear axle demand braking torque and a braking system inverse model; and the pressure of a brake chamber is adjusted through a brake pressure adjusting module according to the target brake pressure, so that the response speed and the control precision of the electric compound brake system are improved.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a control method, device, storage medium and commercial vehicle of an electric composite braking system. Background technique [0002] In related technologies, the development process of electrification and intelligence of commercial vehicles poses new challenges to the performance upgrade and function expansion of its braking system. The electrification of the whole vehicle makes the motor feedback braking force participate in the dynamic control of the whole vehicle, and the dynamic performance of the air brake power needs to be further improved. The new functions such as adaptive cruise and active collision avoidance required by the intelligentization of the whole vehicle also put forward higher technical requirements for the pressure response speed and pressure regulation accuracy of EBS. In terms of brake chamber pressure regulation, open-loop control is mostly used at pre...
