Abstract

A control system for a vehicle includes a camera disposed at the vehicle and having a field of view rearward of the vehicle, and at least one non-imaging sensor disposed at the vehicle so as to sense a region at least rearward and partially sideward of the vehicle. During a reversing maneuver of the vehicle along a pathway, the control, responsive to processing of image data captured by the camera, determines edges of the pathway. During the reversing maneuver of the vehicle along the narrow pathway, the control, responsive to processing of data sensed by the non-imaging sensor, determines distances to objects present at or near the determined pathway and rearward and sideward of the vehicle. The control, responsive to determination of the pathway and determination of objects present along the pathway, is operable to steer the vehicle along the pathway to reverse the vehicle along the pathway.

Claims

1. A control system for a vehicle, said control system comprising:

a camera disposed at a rear portion of a vehicle and having a field of view rearward of the vehicle;

at least one non-imaging sensor disposed at the vehicle so as to sense a region at least rearward and sideward of the vehicle;

a control unit having an image processor operable to process image data captured by said camera, said control unit operable to process data sensed by said non-imaging sensor;

wherein, during a reversing maneuver of the vehicle along a pathway, said control unit, responsive to processing by said image processor of image data captured by said camera, determines edges of the pathway;

wherein, during the reversing maneuver of the vehicle along the pathway, said control unit, responsive to processing of data sensed by said non-imaging sensor, determines distances to objects present at or near the pathway and in the path of reverse travel of the vehicle; and

wherein said control unit, responsive to determination of the edges of the pathway and determination of objects present along the pathway, is operable to steer the vehicle along the pathway to reverse the vehicle along the pathway without the vehicle departing beyond the determined edges of the pathway.

2. The control system of claim 1, wherein said non-imaging sensor comprises at least one ultrasonic sensor.

3. The control system of claim 1, wherein said non-imaging sensor comprises an ultrasonic sensor at each side rearward corner region of the vehicle.

4. The control system of claim 1, wherein said non-imaging sensor comprises at least one short range RADAR sensor.

5. The control system of claim 1, wherein said non-imaging sensor comprises a short range RADAR sensor at each side rearward corner region of the vehicle.

6. The control system of claim 1, wherein said control unit is operable to determine the pathway and objects responsive to a user input of the vehicle.

7. The control system of claim 1, wherein said control unit, responsive to determination of the pathway and determination of distances to objects present along the pathway, is operable to control the braking system of the vehicle while steering the vehicle along the pathway.

8. The control system of claim 1, wherein said control unit, responsive to processing by said image processor of image data captured by said camera, determines edges of a narrow driveway or alley.

9. The control system of claim 8, wherein said control unit, responsive to processing of data sensed by said non-imaging sensor, determines distances to at least one of a building and a fence at or near the determined narrow driveway or alley and rearward and sideward of the vehicle.

10. The control system of claim 1, wherein said control unit determines the presence of an object in the pathway, and wherein, responsive to determination of an object present in the pathway, said control unit maneuvers the vehicle to avoid the determined object.

11. A control system for a vehicle, said control system comprising:

a camera disposed at a rear portion of a vehicle and having a field of view rearward of the vehicle;

at least one non-imaging sensor disposed at the vehicle so as to sense a region at least rearward and sideward of the vehicle;

a control unit having an image processor operable to process image data captured by said camera, said control unit operable to process data sensed by said non-imaging sensor;

wherein said control unit is operable in a vehicle reversing mode responsive to a user input of the vehicle;

wherein, when operating in the vehicle reversing mode at a driveway, said control unit, responsive to processing by said image processor of image data captured by said camera, determines edges of the driveway;

wherein, when operating in the vehicle reversing mode, said control unit, responsive to processing of data sensed by said non-imaging sensor, determines distances to objects present at or near the driveway and in the path of reverse travel of the vehicle; and

wherein said control unit, when operating in the vehicle reversing mode and responsive to determination of the edges of the driveway and determination of objects present along the driveway, is operable to steer the vehicle along the driveway to reverse the vehicle along the driveway without the vehicle departing beyond the determined edges of the driveway and while maintaining the vehicle at least a predetermined distance from objects present at or near the driveway and in the path of reverse travel of the vehicle.

12. The control system of claim 11, wherein said non-imaging sensor comprises at least one ultrasonic sensor.

13. The control system of claim 11, wherein said non-imaging sensor comprises an ultrasonic sensor at each side rearward corner region of the vehicle.

14. The control system of claim 11, wherein said non-imaging sensor comprises at least one short range RADAR sensor.

15. The control system of claim 11, wherein said non-imaging sensor comprises a short range RADAR sensor at each side rearward corner region of the vehicle.

16. The control system of claim 11, wherein said control unit, when operating in the vehicle reversing mode, determines the presence of an object in the driveway, and wherein, responsive to determination of the object present in the driveway, said control unit maneuvers the vehicle to avoid the determined object.

17. A control system for a vehicle, said control system comprising:

a camera disposed at a rear portion of a vehicle and having a field of view rearward of the vehicle;

at least one non-imaging sensor disposed at the vehicle so as to sense a region at least rearward and sideward of the vehicle;

a control unit having an image processor operable to process image data captured by said camera, said control unit operable to process data sensed by said non-imaging sensor;

wherein said control unit is operable in a vehicle reversing mode responsive to a user input of the vehicle;

wherein, when operating in the vehicle reversing mode at a driveway, said control unit, responsive to processing by said image processor of image data captured by said camera, determines edges of the driveway;

wherein, when operating in the vehicle reversing mode, said control unit determines the presence of at least one of a building and a fence at or near the driveway and rearward and sideward of the vehicle;

wherein said control unit, responsive to processing of data sensed by said non-imaging sensor, determines distances to the determined at least one of a building and a fence at or near the driveway and rearward and sideward of the vehicle; and

wherein said control unit, when operating in the vehicle reversing mode and responsive to determination of the edges of the driveway determination of distances to the at least one of a building and a fence present at or near the driveway, is operable to steer the vehicle along the driveway to reverse the vehicle along the driveway without the vehicle departing beyond the determined edges of the driveway and while maintaining the vehicle at least a predetermined distance from the building or fence present at or near the driveway.

18. The control system of claim 17, wherein said non-imaging sensor comprises at least one ultrasonic sensor.
