Drive assistance system e.g. lane keeping system, operating method for use in motor vehicle, involves automatically deactivating system by boundary condition during exceedance or falling below of threshold value

摘要

The method involves detecting boundary conditions that are representative for reliable operation of a drive assistance system, and determining whether one of the detected boundary conditions exceeds or falls below an assigned threshold value. The system is automatically deactivated by the boundary condition during exceedance or falling below of the threshold value. The system is automatically re-started when the threshold value is further re-crossed, where the threshold values for deactivation and re-starting are different from each other.
