The introduction of anti-lock braking system (ABS) has been regarded as one of the solutions for braking performance issues due to its notable advantages. The subject had been extensively being studied by researchers until today, to improve the performance of the todays vehicles particularly on the brake system. In this paper, a basic modeling of an ABS braking system via slip control has been introduced on a quarter car model with a conventional hydraulic braking mode. Results of three fundamental controller designs used to evaluate the braking performance of the modeled ABS systems are also been presented. This revisited modeling guide, could be a starting point for new researchers to comprehend the basic braking system behavior before going into more complex braking systems studies.

This paper aims to simulate the effects of different friction models on tire braking. A truck radial tire (295/80R22.5) was modeled and the model was validated with tire deflection. An exponential decay friction model that considers the effect of sliding velocity on friction coefficients was adopted for analyzing braking performance. The result shows that the exponential decay friction model used for evaluating braking ability meets design requirements of antilock braking system (ABS). The tire-pavement contact stress characteristics at various driving conditions (static, free rolling, braking, camber, and cornering) were analyzed. It is found that the change of driving conditions has direct influence on tire-pavement contact stress distribution. The results provide the guidance for tire braking performance evaluation.

Antilock Braking System

This project aims at proposing an innovative way to implement the concept of fuzzy logic to an ABS model. The implementation of this project was conducted using simulation of ABS which is a combination from vehicle speed, wheel speed and slip through MATLAB Simulink software. By implementing fuzzy logic to the ABS system, the fuzzy logic can facilitate in improving the ABS abilities. The ABS model is developed and fuzzy logic controller is implemented to the model. The performance of the Fuzzy ABS is analyzed. The result shows that the fuzzy logic controller can facilitates the performance of the ABS by reducing the stopping time and maintaining the slip value near to 0.2.

A regenerative brake system is an effective way of recovering energy that would be lost as heat during brake operation, and such systems are widely used in hybrid and electric vehicles. This paper presents a multi-objective method for allocating brake torque between the hydraulic and regenerative brake systems using model predictive control. The proposed control method has two objectives: bandwidth-based torque allocation and reduction in driveshaft vibrations. A quarter-car model with a PMSM electric drive system is used to investigate this control method’s effectiveness. The simulation results show that the vehicle stopping distance and the drive shaft vibrations will be reduced with the proposed control strategy.

Driving Stability

A novel hybrid antilock braking system (ABS) with the combination of auxiliary brake and a multipole magnetorheological (MR) brake was proposed in this paper. The MR brake with innovative operation concept can replace existed hydraulic brake system or works as an auxiliary brake. Two simulation models of the MR brakes, inner rotor and outer rotor structures, have been built. The outer rotor design was chosen due to its better braking performance and suitable mechanism for using on motorcycle. After that, motorcycle simulation software was employed to validate the hybrid ABS system under appropriated working condition. Two controllers, the ordinary and self-organizing fuzzy logic controllers (FLC and SOFLC), were evaluated on ABS performance to pick the suitable one. Simulation results confirm the more adaptations to different road conditions of the SOFLC with 18% higher brake performance compared to ones of ordinary FLC. Brake performance can increase 12% more with the combination of SOFLC and road condition estimator (RCE). It is concluded that this hybrid ABS is feasible for actual application by effectively improving the brake performance for ensuring driving stability.

ABSTRACT This paper presents simulation and experimental results that outline the interaction between a tire's torsional dynamic properties and antilock braking system (ABS) during a hard braking event. Previous work has shown the importance of the coupled dynamics of the tire's belt, sidewall, and wheel/hub assembly on braking performance for a wheel acceleration-based ABS controller. This work presents findings based on a proprietary slip-based ABS controller. A comprehensive system model including tire torsional dynamics, dynamics of the tread–ground friction (LuGre friction model), and dominant brake system hydraulic dynamics was developed for simulation studies on this slip-based controller. Results from key sensitivity studies of tire torsional parameters are presented along with experimental results obtained on a quarter car braking test rig. In this work, it was found that within a reasonable tire design space (with respect to tire torsional properties), the ABS algorithm tested was extremely robust to changing these parameters. The main conclusion of this result is that when a consumer replaces his or her tires with different (than original equipment) tires, there should be little effect on braking performance.

The Difference

A new concept for a mechanical antilock braking system (ABS) with a centrifugal braking device (CBD), termed a centrifugal ABS (C-ABS), is presented and developed in this paper. This new CBD functions as a brake in which the output braking torque adjusts itself depending on the speed of the output rotation. First, the structure and mechanical models of the entire braking system are introduced and established. Second, a numerical computer program for simulating the operation of the system is developed. The characteristics of the system can be easily identified and can be designed with better performance by using this program to studying the effects of different design parameters. Finally, the difference in the braking performance between the C-ABS and the braking system with or without a traditional ABS is discussed. The simulation results indicate that the C-ABS can prevent the wheel from locking even if excessive operating force is provided while still maintaining acceptable braking performance.
