Abstract
Based on the matching relationship between curve I of ideal braking force distribution and curve β of brake’s braking force distribution, the effect of hydraulic retarder on braking stability of coach is analysed, and the ideal braking force distribution strategy between hydraulic retarder and friction brake is put forward. The coordination control strategy of braking force between hydraulic retarder and friction brake is analyzed, and the dynamic coordination control strategy based on double closed-loop control structure and the coordination control algorithm with Anti-lock brake system (ABS) based on state machine are put forward. According to the above-mentioned coordination control strategy between hydraulic retarder and friction brake, the braking torque of hydraulic retarder can be made full use of and the degree of wear and heat load of friction brake can be greatly reduced in the premise of ensuring braking safety and comfort.
