Abstract

A method for avoiding or reducing damage to a parked vehicle caused by a collision with an approaching vehicle performing a parking operation included determining, by the parked vehicle, a risk of collision, transmitting a warning signal if the risk of collision is sufficiently high, monitoring whether the approaching vehicle reacts to the warning signal, and performing a maneuver by the parked vehicle to avoid or reduce collision damage if there is no reaction. The maneuver may permit a controlled contact between the parked vehicle and the approaching vehicle to minimize the force of the contact. After such a controlled contact, a braking torque exerted by the parked vehicle is increased. Following completion of the damage avoidance maneuver, an estimate of the extent of the completed damage prevention is made and provided to the owner of the parked vehicle (including information about potential saved repair costs).

Claims

1. A method for reducing a likelihood and/or severity of damage to a parked vehicle caused by a collision with an approaching vehicle performing a parking operation, comprising:

by the parked vehicle,

operating a system on-board the parked vehicle to detect the approaching vehicle;

determining a risk of collision between the parked vehicle and the approaching vehicle;

transmitting at least one of an off-board audible and an off-board visible warning signal perceptible to a driver of the approaching vehicle if the risk of collision is sufficiently high;

operating the system to monitor whether the approaching vehicle reacts to the warning signal;

if the approaching vehicle does not react to the warning signal, moving the parked vehicle away from the approaching vehicle to prevent a distance between the parked vehicle and the approaching vehicle from falling below a minimum distance; and

after completion of the maneuver, estimating an extent of damage avoided by the movement of the parked vehicle.

2. The method of claim 1, wherein transmission of the warning continues until the movement of the parked vehicle is complete.

3. The method of claim 1, wherein a characteristic of the warning signal is determined based upon on an estimated probability of a collision and/or upon an expected extent of collision damage.

4. The method of claim 1, wherein the risk of collision is defined by a speed of the approaching vehicle exceeding a predefined speed limit.

5. The method of claim 1, wherein the risk of collision is defined by a distance between the approaching and parked vehicles falling below a predefined distance limit.

6. A method for collision avoidance by a parked vehicle, comprising:

by the parked vehicle,

responsive to a detected risk of collision with an approaching vehicle, transmit an off-board warning perceptible to a driver of the approaching vehicle;

responsive to no reaction to the warning by the approaching vehicle, maneuver the parked vehicle such that a distance between the parked vehicle and the approaching vehicle does not fall below a minimum distance; and

after completion of the maneuver, estimating an extent of damage avoided by performing the maneuver.

7. The method of claim 6, wherein transmission of the warning continues until the maneuver is completed.

8. The method of claim 6, wherein a characteristic of the warning signal is determined based upon on an estimated probability of a collision and/or upon an expected extent of collision damage.

9. The method of claim 6, wherein the detected risk of collision is defined by a speed of the approaching vehicle exceeding a predefined speed limit.

10. The method of claim 6, wherein the detected risk of collision is defined by a distance between the approaching and parked vehicles falling below a predefined distance limit.

11. The method of claim 6, wherein the detected risk of collision is defined by a speed of the approaching vehicle exceeding a predefined speed limit.

12. A method for collision avoidance by a parked vehicle, comprising:

by the parked vehicle,

responsive to a detected risk of collision with an approaching vehicle, transmit an off-board warning perceptible to a driver of the approaching vehicle;

responsive to no reaction to the warning by the approaching vehicle, maneuver the parked vehicle to avoid collision; and

after completion of the maneuver, estimating an extent of damage avoided by performing the maneuver.

13. The method of claim 12, wherein transmission of the warning continues until the maneuver is completed.

14. The method of claim 12, wherein a characteristic of the warning signal is determined based upon on an estimated probability of a collision and/or upon an expected extent of collision damage.

15. The method of claim 12, wherein the detected risk of collision is defined by a distance between the approaching and parked vehicles falling below a predefined distance limit.
