abstract: Abstract In this paper, an Anti lock braking system (ABS) is designed using a fuzzy logic controller (FLC) The FLC is designed in 0.35 mm standard CMOS process and this design of the circuit makes it having high speed and low power consumption. Also, all the controlling signals and input signals are in voltage form and there is no need for digital programming. Voltage mode design of the circuits leads to the convenient use of FLC with sensors. The objective function is designed to keep the wheel slip to a desired level so that maximum wheel tractive force and maximum vehicle deceleration are achieved. By training this function to the Adaptive Nero Fuzzy Inference System (ANFIS) of MATLAB software the main parameters of fuzzy controller singletons and shape of Membership Function Generators (MFGs) are measured, then all the circuits of the proposed fuzzy logic controller is designed using Complementary Metal Oxide Semiconductor (CMOS) circuits, at the end simulation results of the fuzzy logic controller using Hspice simulator and BSIM3v3 (Berkeley Short Channel Insulated gate field effect transistor Model) parameters verifies the performance and functionality of the design.

abstract: Anti lock braking system (ABS) is an active safety system for vehicle, it operates by preventing the wheels from locking up during braking. According to a lot of research, the effectiveness of ABS in reducing crashes is significant. To design the ABS system, establishing an ABS test bench, which is capable for analyzing the ABS braking performance, the individual ABS components performance, and the whole ABS durability is necessary. In this work, we upgraded our original hydraulic control unit performance test bench to satisfy the above mentioned goals by further enhancing the function in this module test bench and further designing and realizing an ABS dynamic braking performance test bench. The module test bench can be used for evaluating the performance of whole ABS product quickly and precisely. In addition, the durability of the hydraulic control units and the control logic of the ABS can be performed and analyzed by the aid of a virtual speed signal circuit built in this test bench. On the other hand, the designed ABS dynamic performance test bench is aimed for testing the braking performance of ABS by using the flywheel design to simulate the field test environment. Finally, These two test benches are eventually integrated to form a versatile test platform. Through the effort, in the future, it is possible to perform effective performance assessment on commercial ABS systems and to develop new control strategies based on this test platform.

abstract: With the development of in wheel technology (IWT) the design of the electric vehicles (EV) is getting much improved. The anti lock braking system (ABS) which is a safety benchmark for automotive braking, is particularly important. Installing the braking motor at each fixed position of the wheel improves the intelligent control of each wheel. The nonlinear ABS with robustness performance is highly needed during the vehicle's braking. The anti lock braking controller (CAB) designed in this paper considered the well known adhesion force, the resistance force from air and the wheel rolling friction force, which bring the vehicle model closer to the real situation. A sliding mode wheel slip ratio controller (SMWSC) is proposed to yield anti lock control of wheels with an adaptive sliding surface. The vehicle dynamics model is established and simulated with consideration of different initial braking velocities, different vehicle masses and different road conditions. By comparing the braking effects with various CAB parameters, including stop distance, braking torque and wheel slip ratio, the SMWSC proposed in this paper has superior fast convergence and stability characteristics. Moreover, this SMWSC also has an added road detection module, which makes the proposed braking controller more intelligent. In addition, the important brain of this proposed ABS controller is the control algorithm, which can be used in all vehicles' ABS controller design.

abstract: This paper presents a regenerative anti lock braking system control method with road detection capability. The aim of the proposed methodology is to improve electric vehicle safety and energy economy during braking maneuvers. Vehicle body longitudinal deceleration is used to estimate a road surface. Based on the estimation results, the controller generates an appropriate braking torque to keep an optimal for various road surfaces wheel slip and to regenerate for a given motor the maximum possible amount of energy during vehicle deceleration. A fuzzy logic controller is applied to fulfill the task. The control method is tested on a four in wheel motor drive sport utility electric vehicle model. The model is constructed and parametrized according to the specifications provided by the vehicle manufacturer. The simulation results conducted on different road surfaces, including dry, wet and icy, are introduced.

abstract: Anti lock Braking System ABS is a monitoring system aims at preventing locking of vehicle wheels during an emergency braking. When the brake pedal is intensely pressed, the vehicle wheels can be locked and as a result the steering capability will be very poor, the stopping distance may possibly be getting longer and the friction can significantly wear off the vehicle tires. A good Anti lock Braking System device can address these faults by unlocking the wheels. This paper proposes an efficient embedded computing component for anti Lock braking system with the intention of improving the contemporary Anti lock Braking Systems.

abstract: This paper deals with a novel method for integration of the active suspension system and the anti lock braking system. In the proposed method, a new nonlinear controller with state constraints is developed for the active suspension system based on the response prediction of 14 degree of freedom vehicle model. The proposed controller isolates the vehicle from road roughness in normal conditions and assists the anti lock braking system by ensuring a good contact between the tyre and road during hard braking. In addition, the tyre deflection is limited to prevent the threat of tyre bursting. To develop the active suspension system controller, at first, a performance index consisting of a weighted combination of predicted responses of suspension system is expanded as a function of current control input. At the same time, the state constraints of tyre normal force and tyre deflection are transformed to the equivalent constraints of control input by the same prediction approach. Then, the control law is found by minimizing the expanded performance index in the presence of input constraints. The Karush Kuhn Tucker theorem is employed to solve the performed constrained optimization problem analytically. The performance of the proposed active suspension system controller integrated with the designed nonlinear anti lock braking system controller is evaluated for a full vehicle model including roll and pitch motions during braking on irregular random roads. The results show that both the body acceleration and the vehicle stopping distance are decreased for the proposed integrated strategy compared with other conventional strategies.

abstract: Anti lock Braking System (ABS) is a system that automatically adjusts the braking force of the wheels when the vehicle is braking. It can prevent the wheels from locking to obtain the best braking effect, and improve the directional stability of the automobile. In the paper, the ABS system models based on Matlab were established, including single wheel vehicle model, tire model and vehicle braking system model. The Matlab/Simulink simulation environment was used to simulate the braking effect of a car with and without an ABS system by combining specific actual vehicle data. The simulation results confirm the validity and effectiveness of ABS. Introduction In recent years, cars production and ownership are increased rapidly, which brought a lot of harm to the society, such as traffic accidents [1] In order to improve the safety of the car, an Anti lock Braking System (ABS) is added to the conventional braking system. When the vehicle brakes, ABS automatically adjust wheel braking force of each wheel to prevent it from locking, so the braking system of automobiles can obtain the best braking effect, it is considered as one of the effective measures to enhance the driving safety of a car [2,3,4] A simulation algorithm based on Matlab is presented in the paper to confirm the validity and effectiveness of ABS. System Model Based on Matlab Vehicle Dynamics Model. Taking into account the computational complexity and simulation accuracy of the vehicle model, a classic single wheel model is used, which is shown as Fig.1[5] Fig.1. Single wheel vehicle model The required dynamic equations can be established for the two degrees of freedom of the vehicle body in the driving direction and the direction of the wheel around the main axis in the model, thus a simplified vehicle dynamic equation is obtained[5] The motion equation of the vehicle can be described as follows: F v M (1) The wheel dynamic equation can be shown as follows: 3rd International Conference on Automation, Mechanical Control and Computational Engineering (AMCCE 2018) Copyright (c) 2018, the Authors.

abstract: Bench inspection approach for automobile Anti lock Braking System (ABS) has gained research interests recently due to its high efficiency, small site occupation and insusceptibility to environment influences. The current work proposed a novel systematic bench inspection approach for ABS. In order to dynamically simulate various road adhesion coefficients, torque controllers are used for loading different torques to the drums. Furthermore, flywheels are adopted to simulate the translational inertia of the vehicle braking on road for compensating the inertial energy of ABS road experiment on the bench. The principal component analysis (PCA) is applied for accurate and efficient data analysis. The automatic evaluation of ABS is achieved by using the processed PCA data as an input to the back propagation (BP) neural network classifier. The experiments established that the new approach can accurately simulate various road braking conditions. It can be carried out for the inspection of ABS installed in the car.

abstract: The anti lock braking system (ABS) is an essential part in ensuring safe driving in vehicles. The Security of onboard safety systems is very important. In order to monitor the functions of ABS and avoid any malfunction, a model based methodology with respect to structural analysis is employed in this paper to achieve an efficient fault detection and identification (FDI) system design. The analysis involves five essential steps of SA applied to ABS, which includes critical faults analysis, fault modelling, fault detectability analysis and fault isolability analysis, Minimal Structural Over determined (MSO) sets selection, and MSO based residual design. In terms of the four faults in the ABS, they are evaluated to be detectable through performing a structural representation and making the Dulmage Mendelsohn decomposition with respect to the fault modelling, and then they are proved to be isolable based on the fault isolability matrix via SA. After that, four corresponding residuals are generated directly by a series of suggested equation combinations resulting from four MSO sets. The results generated by numerical simulations show that the proposed FDI system can detect and isolate all the injected faults, which is consistent with the theoretical analysis by SA, and also eventually validated by experimental testing on the vehicle (EcoCAR2) ABS.
