Abstract

In one exemplary embodiment of the invention, a vehicle warning system is provided. The system includes a vehicle having a door movable between a closed position and a fully open position, and an outer zone associated with the door. The outer zone defines an area providing a sufficient clearance to move the door to the fully open position. The system further includes an active safety system that monitors the outer zone and generates a warning signal if an object is located within the outer zone such that the door does not have sufficient clearance to move to the fully open position.

Claims

1. A vehicle warning system comprising:

a vehicle having a door movable between a closed position and a fully open position, and an outer zone associated with the door, wherein the outer zone defines an area providing a sufficient clearance to move the door to the fully open position; and

an active safety system that monitors the outer zone and generates a warning signal if an object is located within the outer zone such that the door does not have sufficient clearance to move to the fully open position.

2. The system of claim 1, wherein the warning signal is an audio signal that is output from at least one speaker of the vehicle.

3. The system of claim 1, wherein the warning signal is a visual signal displayed on a display of the vehicle.

4. The system of claim 3, wherein the display comprises at least one of an instrument panel cluster, a dashboard display monitor, and a rear-view mirror.

5. The system of claim 1, wherein the door is at least one of a vehicle tailgate and a vehicle liftgate.

6. The system of claim 1, wherein the active safety system includes one of a forward collision warning system, a rear collision warning system, a forward park assist system, a rear park assist system, a left side object detection system, and a right side object detection system.

7. The system of claim 1, wherein the active safety system includes a radar sensor configured to monitor the outer zone.

8. A vehicle warning system comprising:

a vehicle having a trunk access door movable between a closed position and a fully open position; and

a park assist system that monitors an area within a full park assist range zone, the full park assist range zone including a tailgate access zone that defines a space providing a sufficient clearance to move the trunk access door to the fully open position, wherein the park assist system generates a first warning signal when an object is detected within the full park assist range zone but outside the tailgate access zone, and a second warning signal when the object is detected within the tailgate access zone, and wherein the second warning signal is different from the first warning signal.

9. The system of claim 8, wherein the full park assist range zone further includes a full warning zone separate from the tailgate access zone, wherein the park assist system generates a third warning signal when the object is detected within the full warning zone, and wherein the third signal is different from the first and second warning signals.

10. The system of claim 8, wherein the first warning signal is a first audio signal and the second warning signal is a second audio signal, and wherein the second audio signal is different from the first audio signal.

11. The system of claim 9, wherein the first warning signal is a first audio signal, the second warning signal is a second audio signal, and the third warning signal is a third audio signal, wherein the first, second, and third audio signals are different from each other.

12. The system of claim 11, wherein the first, second, and third audio signals are different from each other in at least one of tone, frequency, and period.

13. The system of claim 8, wherein the first warning signal is a first visual signal displayed on a display of the vehicle and the second warning signal is a second visual signal displayed on the display of the vehicle, and wherein the first visual signal is different from the second visual signal.

14. The system of claim 9, wherein the first warning signal is a first visual signal displayed on a display of the vehicle, the second warning signal is a second visual signal displayed on the display of the vehicle, the third warning signal is a third visual signal displayed on the display of the vehicle, and wherein the first, second, and third visual signals are different from each other.

15. The system of claim 13, wherein the vehicle display is at least one of an instrument panel cluster, a dashboard display monitor, and a rear-view mirror.

16. The system of claim 14, further comprising a camera configured to display a camera view of the area behind the vehicle on the vehicle display, wherein the full warning zone, the tailgate access zone, and the full park assist range zone are displayed on the camera view on the vehicle display.

17. The system of claim 16, wherein the full warning zone is displayed in red, the tailgate access zone is displayed in yellow, and the full park assist range zone is displayed in green.

18. The system of claim 9, wherein the park assist system comprises a rear collision warning system.

19. A method of operating a vehicle warning system for a vehicle having a door movable between a closed position and a fully open position, and an outer zone associated with the door, where the outer zone defines an area providing sufficient clearance to move the door to the fully open position, the method comprising:

monitoring the outer zone with an active safety system; and

generating a warning signal if an object is located within the outer zone such that the door does not have a sufficient clearance to move to the fully open position.

20. The method of claim 19, further comprising at least one of:

outputting the warning signal as an audio signal from at least one speaker of the vehicle; and

outputting the warning signal as a visual signal on a display of the vehicle.
