Abstract

A method is provided for automatically activating a car's side view camera during lane changes and displaying the camera feed on a dashboard mounted display, thereby eliminating blind spots and making the maneuver safer. The system can be configured to anticipate an upcoming lane change based on use of the turn signal alone, or the turn signal in combination with vehicle speed and/or determination of a second vehicle located in the primary car's blind spot. The display of the camera's data feed is terminated after completion of the lane change, where lane change completion is typically based on deactivation of the turn signal or the vehicle crossing over the lane markers.

First claim

What is claimed is:

1 . A method of automatically activating a side view camera mounted to a vehicle, the method comprising the step of:
receiving a first indicator, wherein said first indicator corresponds to an imminent lane change by the vehicle, and wherein said first indicator is received by a vehicle system controller; displaying a data feed from the side view camera upon receipt of said first indicator by said vehicle system controller, wherein said displaying step is performed automatically by said vehicle system controller; completing said imminent lane change by the vehicle; receiving a second indicator, wherein said second indicator corresponds to said step of completing said imminent lane change, and wherein said second indicator is received by said vehicle system controller; and terminating said step of displaying said data feed from the side view camera, 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 first indicator further comprises the step of activating a vehicle turn signal, and wherein said step of activating said vehicle turn signal is performed by a driver of the vehicle.

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

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

5 . The method of claim 3 , wherein said step of deactivating said vehicle turn signal causes performance of said terminating step even if said step of completing said imminent lane change is not performed.

6 . 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 side view camera is only performed upon receipt of said first indicator if said vehicle speed is greater than said preset speed.

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

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

9 . The method of claim 1 , further comprising the steps of:
monitoring a blind spot sensor mounted to the vehicle, wherein an output of said blind spot sensor is communicated to said vehicle system controller; and determining if a second vehicle is located within a region observed by said blind spot sensor, wherein said step of displaying said data feed from the side view camera is only performed upon receipt of said first indicator if said second vehicle is located within said region observed by said blind spot sensor.

10 . The method of claim 1 , further comprising the steps of:
determining a vehicle speed; comparing said vehicle speed to a preset speed; monitoring a blind spot sensor mounted to the vehicle, wherein an output of said blind spot sensor is communicated to said vehicle system controller; and determining if a second vehicle is located within a region observed by said blind spot sensor, wherein said step of displaying said data feed from the side view camera is only performed upon receipt of said first indicator if said vehicle speed is greater than said preset speed and if said second vehicle is located within said region observed by said blind spot sensor.

11 . The method of claim 1 , wherein said step of receiving said first indicator further comprises the step of activating a vehicle turn signal, wherein said vehicle turn signal corresponds to either a vehicle left turn signal or a vehicle right turn signal, and wherein said step of displaying said data feed further comprises the step of selecting a left side view camera data feed if said vehicle turn signal corresponds to said vehicle left turn signal and selecting a right side view camera data feed if said vehicle turn signal corresponds to said vehicle right turn signal.

12 . The method of claim 1 , wherein said step of displaying said data feed from the side view camera further comprises the step of displaying said data feed on either a primary display or a secondary display, wherein said method further comprises the step of selecting between said primary display and said secondary display.

13 . The method of claim 12 , wherein said step of selecting between said primary display and said secondary display is preset and performed by a vehicle manufacturer.

14 . The method of claim 12 , wherein said step of selecting between said primary display and said secondary display is performed by a vehicle user.

15 . The method of claim 12 , wherein said step of selecting between said primary display and said secondary display is preset by a vehicle user.

16 . The method of claim 1 , wherein said step of displaying said data feed further comprises the step of displaying a left side view camera data feed and a right side view camera data feed.

17 . The method of claim 1 , further comprising the step of monitoring a current vehicle location relative to a plurality of lane markers, wherein said step of receiving said second indicator further comprises the step of determining when said current vehicle location relative to said plurality of lane markers indicates performance of said step of completing said imminent lane change.

18 . The method of claim 1 , wherein if said step of completing said imminent lane change is not performed within a preset period of time after performing said step of displaying said data feed, then said method further comprises the step of automatically terminating said step of displaying said data feed from the side view camera.
