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 wh...

Predicting the tractive limitations of locomotion gears is of critical importance in a robotic vehicle system on natural terrain. In particular, it is imperative for an unmanned mobile robot to avoid getting stuck in loose soil to retain its mobility. From this perspective, this paper attempts to theoretically predict the limitations of a typical wheel in such loose soil based on traditional so...

the focus of studies in the field of passive walking has often been on straight walking, while less attention has been paid to the field of turning motions. in this paper, the passive motions of a finite width rimless wheel as the simplest 3d model of passive biped walkers was investigated with a focus on turning motions. for this purpose, the hybrid model of the system consisting of continuous...

In any brake system of an automobile or passenger vehicle, an increase in Master/Wheel cylinder diameter ratio leads to an increase in brake efficiency. This paper focuses on Master/Wheel cylinder diameter effect on the brake efficiency. A VISUAL BASIC computer code was developed for computation of Master/Wheel cylinder diameter ratio corresponding to break efficiency. Aided by the developed so...

This paper covers the development, design and simulation of an automatic real time control system applied in mechanical system of recovery of spur gears. using modern techniques of automatic welding. This automatic system permits to recover the initial geometric contour of the wheel by performing automatic welding runs across each tooth, keeping the mechanical properties intact. The thermal mod...

The paper presents the modeling and control design of a variable-geometry suspension system, which is applied as independent wheel steering for in-wheel electric vehicles. The variablegeometry suspension modifies the tilting of the wheel, which has an effect on the steering of the wheels through the variation of the scrub radius. In the paper the model of the suspension-steering system and the ...

This paper presents an integration design scheme and an optimization control strategy for electric wheels to suppress the in-wheel vibration and improve vehicle ride comfort. The in-wheel motor is considered as a dynamic vibration absorber (DVA), which is isolated from the unsprung mass by using a spring and a damper. The proposed DVA system is applicable for both the inner-rotor motor and oute...

This study presents evaluation of effect of in-wheel electric motors mass on the performance of passive and active suspension systems using matlab. Linear Quadratic Regulator (LQR) is one of more common control methods which is used to complete the design of the active suspension system in this paper .Unsprung mass is one of the important parameters which effects on road holding and ride comfor...

Steer by wire system can be free to design steering force transmission characteristics and angular displacement transfer characteristics, which can realize the coordination of portability, the driver steering road feel and handling stability. The dynamics models of steer by wire and vehicle system are established. Control strategy of front wheel angle based on fuzzy adaptive PID control is put ...

STUDY OBJECTIVE We assess the relationship between steering wheel deformity and serious thoracic or abdominal injury among drivers and front seat passengers involved in motor vehicle crashes, while adjusting for important crash factors. METHODS This was a national population-based cohort of adults involved in motor vehicle crashes from 1995 to 2002 and included in the National Automotive Samp...
