METHOD FOR FREEING A VEHICLE BY ROCKING WHEN THE VEHICLE GOT STUCK

摘要

A method for releasing a vehicle from a recognized stuck condition including initiating a rocking-free process which is continued until the rocking-free process is automatically discontinued. The rocking-free process is discontinued after the registration and persistence of a vehicle movement for a predetermined time span while, at the same time, vehicle acceleration is registered for the predetermined time span, the extremes of the acceleration during the time span lie within a band-width-limited vehicle acceleration function range whose limits correspond almost to the global extremes of the vehicle's acceleration, or after reaching and maintaining or exceeding a vehicle speed limit value for a predetermined time span and reaching or exceeding a steering path limit value during the predetermined time span, or after the activation of a door switch which was inactive before the beginning of the rocking-free process and maintaining the switch active for a predetermined time span.
