Vehicle Braking Control Using Sliding Mode Control
In recent years, anti lock brake system and brake by wire are proposed in the vehicle control using a brake, and the braking power is expected to be improved more than ever. The researches such as an application to the ABS of Siliding mode control which considered a actuator dynamics [1] and a hybrid control of the brake using model reference adaptive control [2] are done so far. However, in the former case, speed following that be comes a target exists physically impossible situation by saturation of tire frictional force because only speed following is one. In the latter, the model error is caused because the simulation model and the controller design model are different. There fore, there is a problem that an accurate follow can not be done. In this paper, the braking control is performed using the sliding mode control [3] which has high robustness for disturbance that fulfils matching conditions. In so doing, it aims attheachievement of optimal braking control to switch wheel speed following to slip rati o following.
