Abstract

Because of the nonlinear feature of tire force, the anti-lock braking system (ABS) research based on wheel slip control (WSC) is widely used even without the measured wheel slip and road friction. Combined with the WSC technology, the four-wheel ABS with the fuzzy sliding mode (FSM) control method is introduced in this paper. Unlike most single-wheel independent ABS, this design has more advantages when braking under the unusual road conditions, such as the transition of road conditions, the split-road conditions between the left-side wheels and the right-side wheels, even the extreme situation in which road conditions of each wheel are different, as it has the smooth-braking judgment module that is designed for wheel-to-wheel control. Besides, based on the nonlinear function of the tire-road interaction (TRI) model, the designed road condition detection module provides characteristics of the braking road that are required in the ABS operation. The model of vehicle and tire is established in Simulink by using parameters of a vehicle: BYD F0. The effectiveness of the proposed four-wheel ABS is validated through the combined use of MATLAB and RT-lab and via substantial simulations and RT-LAB co-simulations.
