Estimation of Reference Vehicle Speed based on T-S Fuzzy Model

To estimate the reference vehicle speed, the vehicle dynamic and wheel dynamic is modeled. Based on analyzing the braking process and dynamic model of vehicle and wheel, the T-S fuzzy model of vehicle deceleration is established. Then the reference vehicle speed estimation approach by virtue of T-S fuzzy model is proposed. At last, the ABS control algorithm is developed and road test is done. Experiment results show that the proposed approach is of high accurate.
