Abstract

A method is provided for automatically activating a car's cross traffic camera system when turning a corner and displaying the camera feed on a dashboard mounted display, thereby enhancing cross traffic visibility and making the maneuver safer. The system can be configured to anticipate an upcoming turn based on use of the turn signal alone, or the turn signal in combination with vehicle speed. The display of the camera's data feed is terminated after completion of the turn, where turn completion is typically based on (i) deactivation of the turn signal, (ii) the position of the steering wheel, or (iii) vehicle speed.

First claim

What is claimed is:

1. A method of automatically activating a cross traffic camera system mounted to a vehicle, the method comprising the step of:
activating a vehicle turn signal, wherein a first indicator of said step of activating said vehicle turn signal is received by a vehicle system controller;
displaying a data feed from the cross traffic camera system upon performance of said activating step and receipt of said first indicator by said vehicle system controller, wherein said displaying step is performed automatically by said vehicle system controller, wherein said step of displaying said data feed from the cross traffic camera system further comprises:
displaying said data feed on either a primary display or a secondary display; and
selecting between said primary display and said secondary display, wherein said step of selecting between said primary display and said secondary display is preset and performed by a vehicle manufacturer;

completing a vehicle turn;
receiving a second indicator corresponding to said step of completing said vehicle turn, wherein said second indicator is received by said vehicle system controller; and
terminating said step of displaying said data feed from the cross traffic camera system, wherein said terminating step is performed after said second indicator is received by said vehicle system controller, and wherein said terminating step is performed automatically by said vehicle system controller.

2. The method of claim 1 , wherein said step of receiving said second indicator further comprises the step of deactivating said vehicle turn signal.

3. The method of claim 2 , wherein said step of deactivating said vehicle turn signal is performed automatically by the vehicle after the vehicle performs said step of completing said vehicle turn.

4. The method of claim 1 , further comprising the steps of:
determining a vehicle speed; and
comparing said vehicle speed to a preset speed, wherein said step of displaying said data feed from the cross traffic camera system is only performed upon receipt of said first indicator if said vehicle speed is lower than said preset speed.

5. The method of claim 4 , further comprising the step of setting said preset speed, wherein said step of setting said preset speed is performed by said vehicle manufacturer.

6. The method of claim 4 , further comprising the step of setting said preset speed, wherein said step of setting said preset speed is performed by a vehicle user.

7. The method of claim 4 , further comprising the step of setting said preset speed to a value of 10 mph or less.

8. The method of claim 1 , wherein said step of displaying said data feed from the cross traffic camera system further comprises the step of displaying a left side view camera data feed and a right side view camera data feed.

9. The method of claim 1 , wherein said step of displaying said data feed from the cross traffic camera system further comprises the step of displaying a front view camera data feed.

10. The method of claim 1 , wherein said step of displaying said data feed from the cross traffic camera system further comprises the step of displaying a front view camera data feed and a left side view camera data feed and a right side view camera data feed.

11. The method of claim 1 , further comprising the step of monitoring a current steering wheel position relative to a nominal steering wheel center position, wherein said step of receiving said second indicator further comprises the step of determining when said current steering wheel position relative to said nominal steering wheel center position indicates performance of said step of completing said vehicle turn.

12. The method of claim 1 , further comprising the steps of:
determining a vehicle speed; and
comparing said vehicle speed to a preset speed, wherein said terminating step is performed after said vehicle speed exceeds said preset speed and upon receipt of said second indicator.

13. A method of automatically activating a cross traffic camera system mounted to a vehicle, the method comprising the step of:
activating a vehicle turn signal, wherein a first indicator of said step of activating said vehicle turn signal is received by a vehicle system controller;
displaying a data feed from the cross traffic camera system upon performance of said activating step and receipt of said first indicator by said vehicle system controller, wherein said displaying step is performed automatically by said vehicle system controller, wherein said step of displaying said data feed from the cross traffic camera system further comprises:
displaying said data feed on either a primary display or a secondary display; and
selecting between said primary display and said secondary display, wherein said step of selecting between said primary display and said secondary display is performed real-time by a vehicle user;

completing a vehicle turn;
receiving a second indicator corresponding to said step of completing said vehicle turn, wherein said second indicator is received by said vehicle system controller; and
terminating said step of displaying said data feed from the cross traffic camera system, wherein said terminating step is performed after said second indicator is received by said vehicle system controller, and wherein said terminating step is performed automatically by said vehicle system controller.

14. The method of claim 13 , wherein said step of receiving said second indicator further comprises the step of deactivating said vehicle turn signal.

15. The method of claim 14 , wherein said step of deactivating said vehicle turn signal is performed automatically by the vehicle after the vehicle performs said step of completing said vehicle turn.

16. The method of claim 13 , further comprising the steps of:
determining a vehicle speed; and
comparing said vehicle speed to a preset speed, wherein said step of displaying said data feed from the cross traffic camera system is only performed upon receipt of said first indicator if said vehicle speed is lower than said preset speed.

17. The method of claim 16 , further comprising the step of setting said preset speed, wherein said step of setting said preset speed is performed by a vehicle manufacturer.

18. The method of claim 16 , further comprising the step of setting said preset speed, wherein said step of setting said preset speed is performed by said vehicle user.

19. The method of claim 16 , further comprising the step of setting said preset speed to a value of 10 mph or less.

20. The method of claim 13 , wherein said step of displaying said data feed from the cross traffic camera system further comprises the step of displaying a left side view camera data feed and a right side view camera data feed.

21. The method of claim 13 , wherein said step of displaying said data feed from the cross traffic camera system further comprises the step of displaying a front view camera data feed.

22. The method of claim 13 , wherein said step of displaying said data feed from the cross traffic camera system further comprises the step of displaying a front view camera data feed and a left side view camera data feed and a right side view camera data feed.

23. The method of claim 13 , further comprising the step of monitoring a current steering wheel position relative to a nominal steering wheel center position, wherein said step of receiving said second indicator further comprises the step of determining when said curre
