Abstract

A vehicle includes a proximity sensor that senses a distance to objects located to at least one side of the vehicle, a camera mounted at the front of the vehicle, a display for displaying video from the camera, and processing circuitry that detects a transition of the vehicle from surroundings of the vehicle in which at least one object located to the side of the vehicle is within a predetermined proximity threshold distance to surrounding of the vehicle in which no objects are located to the side of the vehicle within the predetermined proximity threshold distance, and in response to determining that, at least, the proximity sensor has detected the transition, the processing circuitry is configured to display video from the camera on the display of the vehicle. Additional criteria for displaying the video can include vehicle speed, distance traveled prior to the transition, duration for which the state prior to the transition was maintained, and the state of the vehicle's turn signal.

First claim

I claim:

1. A vehicle comprising:
a front;
a first side;
a second side;
a proximity sensor configured to sense a distance to objects located to at least one of the first side and the second side of the vehicle;
a camera mounted at the front of the vehicle, the camera configured to include a field of view that includes a view to at least one of the first side and the second side of the vehicle;
a display in the vehicle; and
processing circuitry coupled to the proximity sensor, the camera, and the display, wherein the processing circuitry is configured to:
determine that, at least, the proximity sensor has detected a transition of the vehicle from surroundings of the vehicle in which at least one object located to at least one of the first side of the vehicle and the second side of the vehicle is within a predetermined proximity threshold distance to surroundings of the vehicle in which no objects are located to the at least one of the first side of the vehicle and the second side of the vehicle within the predetermined proximity threshold distance, and
in response to determining that, at least, the proximity sensor has detected the transition, the processing circuitry is configured to display video from the camera on the display of the vehicle, wherein
in determining that, at least, the proximity sensor has detected the transition, the processing circuitry is further configured to determine that prior to the transition the vehicle was traveling at a speed less than a predetermined speed threshold, and
the display of the video from the camera on the display is also conditioned on the vehicle having been traveling at the speed less than the predetermined speed threshold prior to the transition.

2. The vehicle according to claim 1 wherein:
in determining that, at least, the proximity sensor has detected the transition, the processing circuitry is further configured to determine that prior to the transition, the vehicle had traveled a distance at least equal to a predetermined travel distance while the vehicle was in the surroundings of the vehicle in which at least one object was located to at least one of the first side of the vehicle and the second side of the vehicle within the predetermined proximity threshold distance.

3. The vehicle according to claim 1 wherein:
in determining that, at least, the proximity sensor has detected the transition, the processing circuitry is further configured to determine that prior to the transition, for at least a predetermine period of time the vehicle was in the surroundings of the vehicle in which at least one object was located to at least one of the first side of the vehicle and the second side of the vehicle within the predetermined proximity threshold distance.

4. The vehicle according to claim 1 wherein:
in determining that, at least, the proximity sensor has detected the transition, the processing circuitry is further configured to determine when a turn signal of the vehicle has been activated.

5. The vehicle according to claim 1 wherein:
the proximity sensor has a horizontal field of view at least partly overlaps the range of 75° to 85° degrees from a longitudinal axis of the vehicle.

6. The vehicle according to claim 1 wherein:
the field of view of the proximity sensor has a horizontal angular extent of at least 10 degrees.

7. A method of operating a camera and a display of a vehicle in response to a proximity sensor of the vehicle, the method comprising:
determining with processing circuitry that, at least, the proximity sensor has detected a transition of the vehicle from surroundings of the vehicle in which at least one object located to at least one of the first side of the vehicle and the second side of the vehicle is within a predetermined proximity threshold distance to surroundings of the vehicle in which no objects are located to the at least one of the first side of the vehicle and the second side of the vehicle within the predetermined proximity threshold distance; and
in response to determining that, at least, the proximity sensor has detected the transition, using the processing circuitry to display video from the camera on the display of the vehicle, wherein
determining that, at least, the proximity sensor has detected the transition, includes determining with the processing circuitry that prior to the transition the vehicle was traveling at a speed less than a predetermined speed threshold, and
the display of the video from the camera on the display is also conditioned on the vehicle having been traveling at the speed less than the predetermined speed threshold prior to the transition.

8. The method according to claim 7 wherein:
determining that, at least, the proximity sensor has detected the transition, includes determining that prior to the transition, the vehicle had traveled a distance at least equal to a predetermined travel distance while the vehicle was in the surroundings of the vehicle in which at least one object was located to at least one of the first side of the vehicle and the second side of the vehicle within the predetermined proximity threshold distance.

9. The method according to claim 7 wherein:
determining that, at least, the proximity sensor has detected the transition, includes determining that prior to the transition, for at least a predetermine period of time the vehicle was in the surroundings of the vehicle in which at least one object was located to at least one of the first side of the vehicle and the second side of the vehicle within the predetermined proximity threshold distance.

10. The method according to claim 7 wherein:
determining that, at least, the proximity sensor has detected the transition, includes determining when a turn signal of the vehicle has been activated.

11. A non-transitory computer readable medium including programming instructions for
operating a camera and a display of a vehicle in response to a proximity sensor of the vehicle, including programming instructions for:
determining with processing circuitry that, at least, the proximity sensor has detected a transition of the vehicle from surroundings of the vehicle in which at least one object located to at least one of the first side of the vehicle and the second side of the vehicle is within a predetermined proximity threshold distance to surroundings of the vehicle in which no objects are located to the at least one of the first side of the vehicle and the second side of the vehicle within the predetermined proximity threshold distance; and
in response to determining that, at least, the proximity sensor has detected the transition, using the processing circuitry to display video from the camera on the display of the vehicle, wherein
determining that, at least, the proximity sensor has detected the transition, includes determining with the processing circuitry that prior to the transition the vehicle was traveling at a speed less than a predetermined speed threshold, and
the display of the video from the camera on the display is also conditioned on the vehicle having been traveling at the speed less than the predetermined speed threshold prior to the transition.

12. The non-transitory computer readable medium according to claim 11 further including programming instructions for:
determining that, at least, the proximity sensor has detected the transition, includes determining that prior to the transition, the vehicle had traveled a distance at least equal to a predetermined travel distance while the vehicle was in the surroundings of the vehicle in which at least one object was located to at least one of the first side of the vehicle and the second side of the vehicle with
