Abstract
The steering reaction torque is important to car drivers since it has significant influence on the ease of handling vehicle. Even with today's advanced simulation technology, however, it is very difficult to simulate factors such as various steering feelings. The purpose of this study is to develop a steering Hardware-in-the-Loop (HIL) simulator that can quantitatively evaluate a steering system. This simulator can control the reaction torque with an AC servomotor. The validity of this HIL simulator is investigated by comparing the simulation results with those obtained with actual vehicle running test.
