Abstract: A dynamic coordinated control strategy of mechanical brake, motor and electro-hydraulic retarder is proposed for the torque response of composite braking of mechanical brake, motor and electro-hydraulic retarder in high speed electric drive tracked vehicle. The steady-state braking torque is assigned based on braking requirement and vehicle speed, and the dynamic response characteristics of three executive components are considered comprehensively. Based on the dynamic coordinated control strategy for the composite braking of motor and electro-hydraulic retarder and the composite braking of mechanical brake, motor and electro hydraulic retarder, a simulation model of electric drive tracked vehicle transmission system is established, making use of real-time simulation tool to verify the strategy. The simulated results show that the dynamic coordinated control strategy can be used to enhance the response speed of total braking torque, and improve the dynamic response characteristics of the vehicle during braking.
