Abstract

The precondition of realizing logic thresholds based antilock braking system (ABS) is the accuracy calculation of wheel angular acceleration. By analyzing the properties of the output signal of the electromagnetism induction sensor, which is used to measure wheel speed in vehicle antilock braking system, this paper proposes a kind of circuit that can satisfy the requirements of the system. Utilizing the wheel speed signals and applying the Kalman filter technology, the wheel angular acceleration is calculated. The trial results verify the feasibility and validity of this method.
