Device for adjusting the steering angle of vehicle wheels
First Claim
1. In a vehicle having a plurality of steerable wheels and a steering wheel, an apparatus for adjusting the steering angle of at least one steerable wheel of the vehicle, said apparatus comprising:
- sensor means for sensing the steering angle of the vehicle steering wheel, the speed of the vehicle, and a vehicle state variable of the vehicle, said steering angle selected by a driver of the vehicle, said sensor means generating an output signal; and
a controller connected to said sensor means and receiving said sensor means output signal, said controller determining a reference value for said vehicle state variable which is dependent on the vehicle speed and the steering angle;
said controller correcting the steering angle of said steerable wheel such that the vehicle has an understeering steering performance.

Abstract
An apparatus for adjusting the steering angle of at least one steerable wheel of the vehicle includes sensor means for sensing the steering angle of the vehicle steering wheel, the speed of the vehicle, and a vehicle state variable of the vehicle. The steering angle is selected by a driver of the vehicle. The sensor means generates an output signal. A controller is connected to the sensor means and receives the sensor means output signal. The controller determines a reference value for said vehicle state variable which is independent of the vehicle speed and the steering angle. The steering angle is generated independently of the reference value. The controller corrects the steering angle of the steerable wheel such that the vehicle has an understeering or neutral steering performance.
