Preventing undesired steering movements with steered wheels of motor vehicle - using control for determining wheel steering angle and wheel steering force reacting on wheels also steering wheel angle and force at steering wheel

摘要

The control unit (20) includes a timer (21), which is activated if an alteration of the steering wheel angle (beta) or a wheel steering angle (alpha) results. The difference between the steering wheel force (FL) and the wheel steering force (FR) is compared with a limit value (G). With alterations of the wheel steering angle (alpha), within a time window of which no corresp. alignment alteration of the steering wheel angle (beta) has occurred. An adjusting element (22) driven by an electric motor is operated by the control unit, which produces the steering force (R) directed in opposition to the wheel steering force (FR). USE/ADVANTAGE - Measuring values of forces reacting on steering across wheels. Esp. prevention or damping of high forces suddenly occurring on steering wheel.
