Many vehicle control systems were designed and implemented in the last years to enhance performances and stability acting on front and/or rear steering actuators [1,2,3] and/or individual wheel braking [8]; the development of electroactuated differentials allows to transfer torque between wheels from the faster to the slower one in semiactive differentials [11,12,13,14] and in both directions i...

The hydraulic steering mechanism can lead the vehicle’s hydraulic system more complex and the tire wear heavier in the process of steering, which is detrimental to the steering control of the articulated motordriven vehicle. Thus the skid steering mode is implemented in the articulated motor-driven vehicle in this paper. This mode can simplify the vehicle without steering cylinder and it is mor...

This paper aims at describing the architectural model of an adaptive force-feedback for a By Wire steering wheel system. This solution uses a steering wheel to replicate the reactive torque law which allows the driver to complete a precise driving scenario or a task with the higher performances. Then, the steering wheel adapts the reactive torque to the driving scenario. Since the design of thi...

Previously we derived a new measure relating the driver's steering wheel responses to the vehicle's heading error velocity. This measure, the relative steering wheel compensation (RSWC), changes at times coincident with an alerting stimulus, possibly representing shifts in control strategy as measured by a change in the gain between visual input and motor output. In the present study, we sought...

Driving a car has become a challenge for many people despite the fact that evermore technology is built into vehicles in order to support the driver. Above all, the increasing number of in-vehicle information systems (IVIS) is a main source of driver distraction. The fragmentation of IVIS elements in the cockpit increases the attention demand and cognitive load of the driver. In this paper, we ...

This paper describes an agricultural vehicle modified to serve as a research platform for agricultural engineering. A tractor was equipped with a global positioning receiver, inertial/GPS system, geomagnetic direction sensor, and a monochrome camera for local and global sensing. For steering control, the tractor was equipped with an electro-hydraulic proportional steering valve, PWM coil valve ...

Adrian Rodriguez Master Thesis Abstract A steering aid system called active steering is evaluated by simulating different driving events. The active steering solution, which is taken from a scientific paper, has been implemented in Matlab/Simulink. A vehicle model, also implemented in Matlab/Simulink, is used to form a total system and to compare the two systems: a conventional vehicle and a co...

We present a method for trajectory generation for all-wheel steering mobile robots which can account for rough terrain and predictable vehicle dynamics and apply it to the problem of generating optimal motion splines. There has been little work in trajectory generation for vehicles with all-wheel steering capability compared to the Ackermann, differential-drive, or omnidirectional mobility syst...

Due to the removal of the mechanical connection between steering wheel and vehicle wheel, it has become a key issue that how to generate road feel and ensure the safety of wire steering in Steering-By-Wire System. In view of the lack of the road feel and hard to guarantee the security in the process of steer by wire, a new Steering-By-Wire System based on hydraulic is developed to achieve road ...

The controlling behaviour of a vehicle is influenced by the performance of its steering system. The steering system consists of steering wheel, steering column, rack and pinion, steering gearbox, and a linkage system. The vehicle is controlled by the behaviour of the steering gear with the spring loaded rack and pinion. This spring loading arrangement consists of yoke nut, spring, and plunger. ...
