Study of the dynamic threshold and control logic on anti-lock brake system (ABS)

This paper addresses the modeling and control of the motion of a highway vehicle while braking. Especially, a new idea named the dynamic logic threshold control (DLTC) is put forward, also, the dynamic threshold and the corresponding control logic named "four phase" are designed. The simulation results show that the "four phases" control logic using the dynamic logic threshold values achieves the expected performance. The strategy's robustness due to varying speed and different road conditions are examined.
