Steering wheel angle-offset compensating method for motor vehicle, involves guiding back error equation into vehicle model as steering wheel angle-offset, in order to iteratively determine and compensate steering wheel angle-offset

摘要

The method involves computing a yaw rate based on detected steering angle, a vehicle speed and an acceptable steering wheel angle-offset. The computed yaw rate is compared with a measured yaw rate. An error equation is formed from a difference between the computed yaw rate and the measured raw rate. The error equation is guided back into a vehicle model e.g. single track model, as steering wheel angle-offset, in order to iteratively determine and compensate the steering wheel angle-offset. The error equation is multiplied with an amplification factor. An independent claim is also included for a device for compensating steering wheel angle-offset in a motor vehicle.
