Abstract
Technologies and techniques for operating a backup assistance system for a vehicle, wherein the backup assistance system enables travel in reverse along a previously travelled trajectory, wherein a maximum distance for the reverse travel along the previously travelled trajectory is determined and output using a control unit on the basis of an expected error for the reverse travel along the previously travelled trajectory, in which the expected error exceeds a predefined error threshold value.
Claims20
A method for operating a backup assistance system of a vehicle,
- comprising:
- determining, via a control unit, an expected error for reverse travel, wherein the expected error comprises a calculation of a predicted future error determined from travel along a previously travelled trajectory;
- determining, via the control unit, if the 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 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.
A backup assistance system for a vehicle, comprising:
- an actuator;
- and
- a control unit, wherein the control unit is configured to
- determine an expected error for reverse travel, wherein the expected error comprises a calculation of a predicted future error determined from travel along a previously travelled trajectory;
- determine if the expected error for reverse travel meets or exceeds a predefined error threshold value;
- determine a maximum distance for the reverse travel along the previously-travelled trajectory, based on the expected error meeting or exceeding the predefined error threshold value;
- and
- execute an at least partially autonomous reverse travel for the vehicle via the actuator based on the determined maximum distance.
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.
