چکیده
1,2,3 B.E. Scholar BVCOE&RI Nashik(India) ABSTARCT Antiknock braking systems are used in modern cars to prevent the wheels from locking after brakes are applied. The dynamics of the controller needed for antiknock braking system depends on various factors. The vehicle model often is in nonlinear form. Controller demand to provide a controlled torque necessary to maintain optimum value of the wheel slip ratio.The slip ratio is represented in terms of vehicle velocity and wheel rotation.In present work first of all system dynamic equations are explained and a slip ratio is expressed in terms of system variables namely vehicle linear velocity and angular speed of the wheel. By exempt a bias braking force system, response is obtained using Simulation models. Using the linear control strategies like P type, PD type, PI type, POD type the effectiveness of maintaining desired slip ratio is tested. It is always looked that a steady state error of 10% occurring in all the control system models.

DEVELOPMENT OF A DC MOTOR ASSISTED HYDRAULIC BRAKING SYSTEM FOR AUTOMOTIVE USE
ABSTRACT: Deceleration or stopping the vehicle without any diving and lateral acceleration is essential to develop an effective braking system. The hydraulic braking system with intelligent braking called Antilock Braking system (ABS) and Electronic Stability Control (ESC) has been introduced. However, due to the insufficient human effort, the ABS and ESC to some extent, not function well...

متن کاملBond Graph Aided Performance Analysis of Antilock Braking System for a Bicycle Vehicle Model with Camber Angle and Fork Angle
In most studies, braking of vehicle in a straight path has been considered. When vehicle moves in a curved path, the effect of camber angle and fork angle should be considered. The variable camber angle assists braking in a curved road but the turning radius of vehicle changes due to varying camber angle and fork angle. The antilock braking system (ABS) is used for enhancing vehicle directional...
متن کاملTowards a Good ABS Design for more Reliable Vehicles on the Roads
Nowadays, better driving also means better braking. To this end, vehicle designers must find all failures during the design phase of antilock braking systems which play an important role in automobiles safety. However, mechatronic systems are so complex and failures can be badly identified. So it is necessary to propose a design approach of an antilock braking system which will be able to avoid...
