摘要:

為了改善轉向系統助力性能和降低系統功耗,基于直流無(wú)刷電機,研究了電動(dòng)助力轉向系統的結構組成與工作原理,采用Freescale 微控制器MC56F8346作為主控芯片,開(kāi)發(fā)了汽車(chē)電動(dòng)助力轉向系統控制器；將控制器分為控制電路和驅動(dòng)電路兩部分,設計了轉矩、電流等信號采集電路、霍爾位置傳感器的轉子位置信號捕捉電路及驅動(dòng)電路；試驗結果表明,所開(kāi)發(fā)的控制器靜態(tài)功耗低,動(dòng)態(tài)響應快,能夠滿(mǎn)足電動(dòng)助力轉向系統對轉向靈活性、輕便性及可靠性的需求。

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.
