Analysis of the ABS Wheel Speed Signal Error and Method of Equal Period Sampling

摘要：

The measuring error of wheel speed signal of Anti-lock Braking System (ABS) has been analyzed in this paper. It has been concluded that trigger error is the main factor which influences the wheel speed measurement limitation, and the correlation between trigger error and the wheel speed signal are surveyed by experiments. It is necessary in ABS to transform the wheel speed signal sampled in the form of equiangular to the form of equal period. In the low speed measurement situation of lacking wheel speed signal, a prediction algorithm based on polynomial order two fit has been utilized to estimate wheel speed. Simulation results verified the algorithm.
