Steering system e.g. electrical power-assisted steering system, assisting method for motor vehicle, involves estimating effort undergone by steering rack from pinion effort, where speed is obtained from engine rotational speed
The method involves estimating the effort undergone by a steering rack of a steering system from pinion effort exerted by a drive pinion on the steering rack and the speed of the steering rack using a logic controller, where the steering rack is connected to steering wheels of a motor vehicle by its ends. The speed of the steering rack is obtained from rotational speed of an electrical engine of a steering unit, where the rotational speed is measured by a brushless type sensor. The pinion effort is estimated from pinion torque on the steering rack and life situation of the electrical engine.
