基于OSEKturbo操作系统的ABS控制系统

ABS Control System Based on OSEKturbo Operating System

汽车防抱死制动系统简称ABS,ABS的工作原理是通过装在车上的传感器,感知制动轮每一瞬间的运动状态和行驶中轮胎与路面的摩擦。因为ABS对实时性的要求非常高,故主要讨论汽车ABS控制系统的原理与实现。系统采用了16位单片机MC9S12DP256,并移植了OSEKturbo OS,来满足ABS对实时性的要求。

Anti-lock brake system is called ABS for short,and the principle of ABS is through the sensors which are installed in the car,the sensors are used tO know the state of the wheels which are braked every time pointer,and to know the friction between the wheels which are running and road surface. The main content of the article is the theory and the realization of the ABS. Because the Real-time demand for the ABS is very high,The 16-bit singlechip of MC9S12DP256 is used,and the OSEKturbo OS is also transplanted in the article,so the demand of Real-time can be satisfied for the ABS.
