Abstract: The braking response delay of articulated heavy vehicles, the braking in coordination between tractor and semi-trailer, braking impact, etc. affect driving stability. To solve the above problems, the paper designed a configuration scheme and established a model of pneumatic electronic control braking system, and proposed a cooperative braking control strategy for the tractor and semi-trailer. PID control is performed on the braking chamber pressure of the front axle of the tractor first, and then closed-loop feedback control is performed on the braking chamber pressure of the rear axle of the tractor and the axle of the semi-trailer so that the braking chamber pressure of the axle of the semi-trailer can follow the axle of the tractor and respond in time to changes in brake chamber pressure. Simulation results based on TruckSim/AMESim/Simulink verify the effectiveness of the proposed cooperative braking control strategy.

Keywords: articulated vehicles; braking response delay; braking impact; pneumatic electronic control braking system; cooperative braking control.
