In order to solve the problem that the braking torque cannot be accurately adjusted due to the nonlinear time-varying characteristics of pneumatic braking, which affects the braking performance of vehicles, a motor-pneumatic composite layered antilock braking coordinated control strategy is proposed. The proposed strategy combines the advantages of mechanical braking and regenerative braking. In the control decision layer, a fuzzy weight pavement recognition algorithm is designed. Combined with an improved sliding mode control (SMC) algorithm, the optimal total braking torque on the current braking road surface is calculated. Then, under the premise of considering the braking energy recovery, the torque distribution strategy of the composite braking system is proposed, which takes the pneumatic braking torque as the base and the motor braking torque as the compensation torque. Finally, the brake clearance elimination strategy based on prebraking of the executive layer pneumatic braking system is designed. The experimental results show that the control strategy proposed in this article effectively coordinates the mechatronics composite braking system, makes up for the defects of pneumatic braking, realizes the efficient use of road adhesion coefficient, and improves the braking safety and energy recovery performance of the vehicle.
