Abstract
Steer-by-wire system has replaced the conventional mechanical linkages with electronic actuators. In this article, a joystick is utilized to substitute the conventional steering wheel and study the...
Highlights
X-by-wire (Xbw) technology offers the opportunity for developing vehicle dynamics and driver–vehicle interface (human–machine interface (HMI)) with enormous flexibility.[1,2] The application of Xbw technology to vehicle steering system gives birth to the so-called steerby-wire (Sbw) system
According to the three simulation tests described above, it can be seen that all the four joystick steering ratio design algorithms result in far smaller amount of driver steering action than a conventional vehicle equipped with a steering wheel
The subject ratings and the interviews revealed that the variable yaw rate steering ratio design for the joystick Sbw system has the potential to replace the conventional steering wheel while similar vehicle handling can be maintained
Summary
X-by-wire (Xbw) technology offers the opportunity for developing vehicle dynamics and driver–vehicle interface (human–machine interface (HMI)) with enormous flexibility.[1,2] The application of Xbw technology to vehicle steering system gives birth to the so-called steerby-wire (Sbw) system. Computer simulation of steering performances of a conventional vehicle and a joystick Sbw vehicle is presented and discussed for the purpose of validating the four variable steering ratio design methods described in the previous section.
