Abstract:
1. A servo-assisted steering system for a motor vehicle, said motor vehicle including a plurality of steerable wheels, said steerable wheels having a steering angle, said steering system comprising: a steering wheel, said steering wheel presetting a desired steering angle for said steerable wheels; a driving-dynamics member, said driving-dynamics device adapted to superimpose a correction angle on said steering angle, said correction angle based on at least one variable which characterizes said correction angle, said correction angle determined to increase the driving stability of said motor vehicle, said driving-dynamics member comprising a motor for generating said correction angle, said correction angle generated from at least one of the actual acceleration of said motor and the nominal acceleration of said motor; and a variable torque assistance servo drive for generating torque assistance for the steerable wheels as a function of the road speed of said motor vehicle and said at least one variable.
