Anti-lock braking system (ABS) is an automobile safety system for vehicles which will allow controlling wheels of vehicle and providing safety contact on road surface according to driver braking input, avoiding uncontrolled skidding and also preventing the wheels from locking up. The main task of ABS is to press and release the brakes almost 15 times a second, so process of stopping the vehicle...
In this study, a mathematical model of Anti-Lock Braking System (ABS) has been developed and simulated in MATLAB/Simulink environment using bang-bang, fuzzy logic PID controllers. The controllers were used to control the braking force be applied based on various parameters like relative slip, road condition coefficient friction between tire. result was compared analyzed. simulation showed that ...
In this paper, a decentralized integrated control structure ...
A model predictive controller for optimal braking of a road vehicle is proposed. Taking into account the additional information provided by a torque sensor located in the wheel, there is no need to use any longitudinal model of the vehicle. Instead, we detail a way to identify a tire/road characteristic. This on-line reconstruction is based on an estimation of the longitudinal wheel slip and an...
This paper deals with the design and analysis of a super twisting fractional-order sliding mode controller (ST-FOSMC) to adjust vehicle longitudinal dynamic when braking. While loading, road types, modeling uncertainties are time-varying parameters, control law must be robust against these disturbances. Also, aging brake plate may introduce difference between output actuator response that shoul...
Anti-lock braking systems (ABS) are safety and control devices implemented in ground vehicles that prevent the wheel lock-up during panic braking. The existing ABS controls have the ability to regulate the level of pressure to optimally maintain the wheel slip within the vehicle stability range. However, the ABS shows strong nonlinear characteristics in which the vehicles equipped with the exis...
