Abstract

A vehicle contact warning system includes a detector system, a controller and a warning indicator. The detector system detects a distance between a remote vehicle and a host vehicle and whether a signal indicator on the remote vehicle is activated. The controller determines whether at least one of a signal indicator on the host vehicle is activated by a driver of the host vehicle and a speed at which the distance between the host vehicle and the remote vehicle is decreasing is greater than a predetermined speed. The warning indicator notifies the driver of the host vehicle upon the detector system detecting the signal indicator on the remote vehicle and the controller determining that at least one of the signal indicator of the host vehicle is activated and the speed at which the distance between the host vehicle and the remote vehicle is decreasing is greater than the predetermined speed.

Claims

1. A vehicle contact warning system comprising:

a detector system configured to detect a distance between a remote vehicle and a host vehicle equipped with the vehicle contact warning system and whether a signal indicator on the remote vehicle is activated;

a controller programmed to determine whether at least one of a signal indicator on the host vehicle is activated by a driver of the host vehicle and a speed at which the distance between the host vehicle and the remote vehicle is decreasing is greater than a predetermined speed; and

a warning indicator configured to notify the driver of the host vehicle upon the detector system detecting the signal indicator on the remote vehicle and the controller determining that at least one of the signal indicator of the host vehicle is activated and the speed at which the distance between the host vehicle and the remote vehicle is decreasing is greater than the predetermined speed.

2. The vehicle contact warning system according to claim 1, further comprising

a global positioning system (GPS) configured to determine a number of traveling lanes of a road on which the host vehicle is traveling, with the controller being configured to activate the vehicle contact warning system only when the GPS determines that the number of traveling lanes is 3 or more in a direction of travel of the host vehicle.

3. The vehicle contact warning system according to claim 1, wherein

the warning indicator is at least one of a visible indicator, a haptic indicator and an audible indicator.

4. The vehicle contact warning system according to claim 1, wherein

the warning indicator is a haptic indicator including a vibration actuator configured to vibrate at least one of a steering wheel and a driver seat of the host vehicle.

5. The vehicle contact warning system according to claim 1, wherein

the warning indicator is at least one of a visible indicator on an instrument cluster of the host vehicle and a visible indicator generated on a heads-up display.

6. The vehicle contact warning system according to claim 1, wherein

the controller is configured to alter at least one of a direction and a speed of the host vehicle to maintain separation between the host vehicle and the remote vehicle after the controller activates the warning indicator and determines that the speed at which the distance between the host vehicle and the remote vehicle is decreasing is greater than the predetermined speed.

7. The vehicle contact warning system according to claim 1, wherein

the detector system includes a camera disposed on at least one of an external rearview mirror housing and an external surface of the host vehicle.

9. The vehicle contact warning system according to claim 1, wherein

the detector system includes a photo sensor disposed on at least one of an external surface and an external rearview mirror housing of the host vehicle.

10. The vehicle contact warning system according to claim 1, wherein

the detector system is configured to detect a remote vehicle disposed on a third lane of a road when the host vehicle is disposed on a first lane of the road, and

a second lane of the road is situated between the first and second lanes.

8. The vehicle contact warning system according to claim 8, wherein

the camera is pivotally mounted on the external rearview mirror housing.

11. A vehicle contact warning system comprising:

a detector system configured to detect a distance between a host vehicle equipped with the vehicle contact warning system and a remote vehicle and whether a signal indicator on the remote vehicle is activated;

a controller programmed to determine when a signal indicator on the host vehicle is activated by a driver of the host vehicle and a speed at which a distance between the host vehicle and the remote vehicle is decreasing; and

a warning indicator configured to notify the driver of the host vehicle upon the controller determining that the signal indicator of the host vehicle is activated and at least one of the detector system detecting the signal indicator on the remote vehicle and the controller determining that the speed at which the distance between the host vehicle and the remote vehicle is decreasing is greater than a predetermined speed.

12. The vehicle contact warning system according to claim 12, wherein

the warning indicator is at least one of a visible indicator, a haptic indicator and an audible indicator.

13. The vehicle contact warning system according to claim 12, wherein

the warning indicator is a haptic indicator including a vibration actuator configured to vibrate at least one of a steering wheel and a driver seat of the host vehicle.

14. The vehicle contact warning system according to claim 12, wherein

the warning indicator is disposed on an external rearview mirror housing of the host vehicle.

15. The vehicle contact warning system according to claim 12, further comprising

a global positioning system (GPS) configured to determine a number of traveling lanes of a road on which the host vehicle is traveling, with the controller being configured to activate the vehicle contact warning system only when the GPS determines that the number of traveling lanes is 3 or more in a direction of travel of the host vehicle.

16. The vehicle contact warning system according to claim 12, wherein

the controller is configured to alter at least one of a direction and a speed of the host vehicle to maintain separation between the host vehicle and the remote vehicle after the controller activates the warning indicator and determines that the speed at which the distance between the host vehicle and the remote vehicle is decreasing is greater than the predetermined speed.

17. The vehicle contact warning system according to claim 12, wherein

the detector system includes a camera disposed on at least one of an external rearview mirror housing of the host vehicle and an external surface of the host vehicle.

18. The vehicle contact warning system according to claim 19, wherein

the camera is pivotally mounted on the external rearview mirror housing.

19. The vehicle contact warning system according to claim 12, wherein

the detector system includes a photo sensor disposed on at least one an external surface and an external rearview mirror housing of the host vehicle.

20. The vehicle contact warning system according to claim 12, wherein

the detector system is configured to detect a remote vehicle disposed on a third lane of a road when the host vehicle is disposed on a first lane of the road, and

a second lane of the road is situated between the first and second lanes.
