摘要: 机械控制难以满足目前汽车电子业对实时性和安全性的要求。为此,提出一个基于FlexRay总线的线控转向系统设计方案,给出转向盘模块、执行器模块及通信网络的结构及软硬件实现方法。通过引入从电子控制单元,减轻主电子控制单元的负荷,从而更好地实现转向控制。实验结果证明,该设计方案满足系统的实时性要求。

Abstract: Aiming at the problems of efficiency and security, this paper proposes a design of steering-by-wire system based on FlexRay bus, presents the composition of system which is the steering wheel module, the actuator module, connecting by the communications network, and gives software and hardware implementation methods. With the help of the slave electronic control unit, the load of the main electronic control unit is reduced, which can achieve better control of the steering. Experimental results show that the design can realize the real-time control of the steering- by-wire system.

Key words: FlexRay bus, steering-by-wire, master-slave communication, Electronic Control Unit(ECU), real time
