| Abstract: | In order to improve the power steering system performance and reduce system power consumption, the structure and working principle of electric power steering (EPS) system were researched based on brushless DC motor. Using Freescale microcontroller MC56F8346 as the master chip, controller of the vehicle electric power steering system was developed, which consists of two modules that are control circuit and driver circuit. Torque and current signal acquisition circuit and the detecting circuit of rotor position signals of Hall position sensors and driver circuit mode were designed in detail. The test results showed that the developed controller has lower static power consumption and fast dynamic response capability, and can meet the requirements of the electric power steering system for steering flexibility, portability and reliability. |
