Abstract
The invention relates to a power steering system in which the set value for torque or force at the steering wheel is predetermined on the basis of various parameters and information so as to provide the most driving comfort in all conditions of driving the vehicle. The torque or force set value is predetermined on the basis of the sideways acceleration of the vehicle, the acceleration in turn being predetermined mainly from an estimate of the force exerted on the rack, and preferably also predetermined by other methods, with the estimate being weighted among all of the obtained values. Said method is particularly useful for vehicles provided with electrical power steering.
