Abstract

Automatic steering wheel is a basic and crucial part of a driverless vehicle which is highly recognized as the finally trends of vehicle. In comparison with hydraulically power system, the electric power steering (EPS) system is a new power steering system which could provide power when the driver steers. The electronic properties of the EPS are quite desirable for automatic control. A novel automatic steering controller for mass-produced vehicle equipped with EPS system is presented in this paper. This controller steers the wheel by simulate the torque signals which are generated by human drivers. Considering the nonlinearity and uncertainty of steering systems, fuzzy theories are implemented for this system instead of classic control theories such as a PID controller. This system has been tested on real road for its effectiveness.
