The Research and Development of Motor Cooling Control System Based on Electronic Parking Brake Test Bench

Article Preview

Abstract:

When Electronic Parking Brake test bench validates the function of ramp start, Electronic Parking Brake (Simplified as EPB) control motor has been blocked state, the motor heat is large. Followed putting forward the performance required by the motor cooling system, and the cooling control system scheme and the control strategy of intelligent electronic pump motor by building a mathematical module about cooling system of EPB motor, this paper designs and develops the electronic water pump motor controller, including the efficient control on the pump, and the communication with the main controller, which is based on CAN bus and SAE J1939 and optimizes the hardware and software of motor controller so that the pump efficiency may reach 32%. The product-level design, shown by a large number of performances testing, is achieved.
