Claim 14:
15. A method for operating a backup assistance system of a vehicle,
comprising:
obtaining a previously travelled trajectory;
subdividing the previously travelled trajectory into trajectory segments based on shapes of the trajectory segments;
determining an expected error for each respective trajectory segment, wherein the expected error comprises a calculation of a predicted future error determined from travel based on a respective shape of the trajectory segment and a respective speed at which the respective trajectory segment was travelled in a forward direction
determining a respective expected error for reverse travel along the previously travelled trajectory;
determining if the respective expected error for reverse travel meets or exceeds a predefined error threshold value;
determining, via the control unit, a maximum distance for the reverse travel along the previously-travelled trajectory based on the respective expected error meeting or exceeding the predefined error threshold value; and
executing an at least partially autonomous reverse travel for the vehicle based on the determined maximum distance.
