“…Based on the above discussion, the studies on the braking performance of ABS revealed variations in its successful applications, and each control strategy can improve the vehicle braking performance under certain conditions. However, understanding the effects of controllers that account for delays has also gained increasing interest with the complexity of control systems, 10,11 and time delays are frequently the main causes of instability and poor performance of ABS. The delay of ABS mainly includes the following aspects: 6 (1) transmission delay of measurement signal from the sensor to controller, (2) operation delay caused by signal processing of the controller, (3) transmission delay of the control signal from the controller to the actuator and (4) response delay of the actuator, including the response delay of the electromagnetic loop and the time needed to establish the control force.…”

A time delay exists between driver input and vehicle braking state response during the working process of the anti-lock braking system (ABS), and the braking performance of vehicles will be further reduced due to the delay of controllers. This paper investigates a systematic method of stability analysis for time delay ABS, and the analysis focuses on the stability and critical delay algorithm of ABS with delay time. Firstly, the dynamic structure and modelling process of ABS are briefly introduced, and PD control algorithm is adopted to improve the control performance. Then, dynamic models of ABS with time delay are derived, and the full delay stability interval and critical time delay algorithm of ABS are deduced by using the generalized Sturm criterion method. Finally, the validity of the critical delay algorithm by the proposed method and the stability and accuracy of ABS with time delay, different road conditions, vehicle speeds and control parameters are illustrated by numerical simulations, and the results show that the critical time delay algorithm of ABS can be verified under different conditions.
