Method for preventing unwanted deactivation of active parking assistance system

Abstract

During an autonomous or semiautonomous parking maneuver, a driver may typically exert manual control on the steering wheel and the autonomous maneuver will be automatically deactivated. The invention provides a method preventing unwanted deactivation of an active parking assistance system which has occurred in the prior art. During the parking maneuver, a check is made to detect the presence of a deactivation prevention event, and if a deactivation prevention event is present then either an increase is applied to a threshold torque above which the active parking assistance system is deactivated or the automatic deactivation is fully prevented. The presence of the deactivation prevention event may be checked based on a vehicle inclination, a steering angle, or a presence of a curb adjacent the vehicle.
