“…Also longitudinal forces affect the tire dynamics, but at this point, such forces are disregarded and would be further included when vehicle chassis is to be considered. From Figure 5 and by taking into account the electrical and mechanical parameters, the dynamic model of the steering rack and tire subsystem is obtained as given by (5). The aligning forces at the tire, also referred to as self-aligning forces in the literature, are represented by SAT .…”

“…The steering system complements the effort required by the driver to steer the vehicle, by using hydraulic pressure. Meanwhile, electrical assisted steering systems have been introduced recently, which eliminate the requirement of a hydraulic pump or diminish the required effort provided by the hydraulic power, yielding electrohydraulic or electrical assistance to the steering rack [5,6].…”

A vehicle steering by wire (SBW) haptic system based on high gain generalized proportional integral (GPI) observers is introduced. The observers are considered for the estimation of dynamic perturbations that are present at the tire and steering wheel. To ensure efficient tracking between the commanded steering wheel angle and the tire orientation angle, the estimated perturbations are on line canceled. As to provide a haptic interface with the driver, the estimated dynamic effects at the steering rack are fed back to the steering wheel, yielding a master-slave haptic system with bilateral communication. For implementation purposes few sensors and minimum knowledge of the dynamic model are required, which is a major advantage compared to other approaches. Only position tracking errors are fed back, while all other signals are estimated by the high gain GPI observers. The scheme is robust to uncertainty on the input gain and cancels dynamic perturbation effects such as friction and aligning forces on the tire. Experimental results are presented on a prototype platform.

International audienceRecent advances towards steer-by-wire technology have promised significant improvements in vehicle handling performance and safety. This technology inspired from aeronautics, consists in replacing the traditional mechanical linkages and/or hydraulic power assist with electrical equivalents. This paper describes the adopted approach for development of a new dynamic model of a Steer-by-wire system with hydraulic assistance in the case of stopped vehicle. The aim is to establish dynamic equations of the forces and torques exchanged between handwheel and the front wheels during steering operations. Some simulation results are provided. The proposed model will be experimented using a prototype equipped with handwheel feedback system
