Tracking assistance method for motor vehicle, involves continuously correcting slight lateral deviation of vehicle from target trajectory by automatic correction of steering movements by adjusting calculated target wheel steering angle

摘要

The additional hand moments applied to a steering handle of motor vehicle (20) towards the center (23) of a detected driving lane (21) are assisted to driver of the motor vehicle as steering recommendations for the tracking. The slight lateral deviation of the motor vehicle from the target trajectory (26) is continuously corrected by automatic correction of steering movements, by adjusting calculated target wheel steering angle so that motor vehicle maintains the target trajectory when the driver drives along a determined target trajectory. Independent claims are included for the following: (1) electronic rule and control device; and (2) electronic power steering system.
