| Abstract(E) | In order to improve the performance of a vehicle braking control, it is important to estimate friction force characteristics between tire and road. In this paper, an estimation method which estimates parameters concerned with friction force margin is proposed by applying the on-line least sequares method to wheel rotational velocities. Then, the braking control using estimated parameters is proposed. The control aims at constant μrate (i.e. generated friction force/maximum friction force) in order to improve vehicle braking and steering maneuvers. The effect of the control is shown by experiments. |
