Abstract

A system for correcting the steering force of a vehicle having a steering wheel whose rotary motion exerted by a vehicle driver is converted into a turn motion of the steering wheels of the vehicle through a steering mechanism. The system is provided with sensors including a CCD camera for detecting the condition of the road ahead having at least one traffic lane on which the vehicle is traveling and a position of the vehicle with respect to the traffic lane. In the system the desired steering force is determined to be generated by the steering mechanism necessary for keeping the detected position of the vehicle with respect to the traffic lane based on the detected parameter and the steering mechanism is biased such that the steering mechanism generates the desired steering force. Conditions on the next adjacent lanes are monitored and the degree of danger is estimated to determine the biasing force. The system can be realized on muscular-energy steering systems or power-assisted steering systems.
