Abstract

A driver assist system for a vehicle includes an object detection sensor disposed at the vehicle and having an exterior field of view and a receiver operable to receive a wireless communication from a communication device remote from the vehicle. The wireless communication is associated with a driving condition of another vehicle and/or a road condition of interest to the driver of the vehicle. A control is operable to process data captured by the object detection sensor to detect an object exterior of the vehicle. The driver assist system is operable to adjust the data processing responsive at least in part to the received wireless communication. Responsive to the data processing, an alert is operable to alert the driver of the vehicle of a potential hazard and/or a system of the vehicle is operable to control a vehicle function to mitigate or avoid a potential hazard condition.

First claim

The invention claimed is:

1. A driver assist system for a vehicle, said driver assist system comprising:
an object detection sensor disposed at the subject vehicle and having an exterior field of view;
a receiver disposed at the subject vehicle and operable to receive a wireless communication, said wireless communication associated with at least one of (i) a driving condition of another vehicle and (ii) a road condition of interest to a driver of the subject vehicle;
wherein said wireless communication comprises at least one of (a) a car-to-car communication and (b) a communication from a communication system associated with a roadway or infrastructure;
a control disposed at the subject vehicle and operable to process data captured by said object detection sensor to detect an object exterior of the subject vehicle;
wherein said driver assist system is operable to adjust said processing of said data responsive at least in part to said wireless communication received by said receiver;
wherein said control is operable to adjust said processing of said data to a distant mode responsive to said wireless communication being indicative of the subject vehicle traveling along a highway, and wherein, when processing said data in said distant mode, said driver assist system is operable to detect an object approaching the subject vehicle from a first distance from the subject vehicle near the effective range of said object detection sensor;
wherein said control is operable to adjust said processing of said data to a nearby mode responsive to said wireless communication being indicative of the subject vehicle traveling along a city road, and wherein, when processing said data in said nearby mode, said object detection sensor is operable to detect an object of interest at a second distance from the subject vehicle;
wherein said first distance is greater than said second distance and wherein, when processing said data in said nearby mode, said control does not process data to detect objects at the first distance from the subject vehicle;
wherein, responsive to said processing of said data, at least one of (a) an alert is operable to alert the driver of the subject vehicle of a potential hazard and (b) a system of the subject vehicle is operable to control a vehicle function to mitigate or avoid a potential hazard condition; and
wherein said driver assist system is operable to alert the driver of the subject vehicle to not open a vehicle door when the subject vehicle is parked and when said system detects another vehicle approaching the subject vehicle in a side lane adjacent to the subject vehicle.

2. The driver assist system of claim 1 , wherein said object detection sensor comprises a camera having an exterior field of view.

3. The driver assist system of claim 2 , wherein said camera has a field of view forward of the subject vehicle.

4. The driver assist system of claim 1 , wherein said distant mode processing of said data focuses on an area at which it is determined that the object approaching the subject vehicle is located.

5. The driver assist system of claim 4 , wherein said nearby mode processing of said data focuses on an area at which the detected object of interest is located.

6. The driver assist system of claim 1 , wherein said driver assist system is operable to alert the driver of the subject vehicle to not open the vehicle door responsive to the detected approaching vehicle being within a threshold distance of the subject vehicle.

7. The driver assist system of claim 6 , wherein said control adjusts said threshold distance responsive to at least one of (i) a distance from the subject vehicle to the detected approaching vehicle, (ii) a speed of the detected approaching vehicle and (iii) an environment in which the subject vehicle is parked.

8. The driver assist system of claim 1 , wherein, responsive to said processing of said data, an alert is operable to alert the driver of the subject vehicle of a potential hazard.

9. The driver assist system of claim 1 , wherein, responsive to said processing of said data, a system of the subject vehicle is operable to control a vehicle function to mitigate or avoid a potential hazard condition.

10. The driver assist system of claim 1 , wherein, responsive to said processing of said data, an alert is operable to alert the driver of the subject vehicle of a potential hazard and a system of the subject vehicle is operable to control a vehicle function to mitigate or avoid a potential hazard condition.

11. The driver assist system of claim 1 , wherein communication with the remote device is done via a time of flight flash light system.

12. The driver assist system of claim 11 , wherein the remote device comprises another vehicle that is equipped with a driver assist system.

13. The driver assist system of claim 12 , wherein, when the subject vehicle is in range of another vehicle equipped with a driver assist system, the communication between the vehicles is automatically initialized.

14. The driver assist system of claim 13 , wherein, during the initialization, said driver assist systems operate in a handshake mode to set up different time patterns for said time of flight flash light communications to reduce data collisions and disturbing influences when both systems are flashing at the same time.

15. A driver assist system for a vehicle, said driver assist system comprising:
an object detection sensor disposed at the subject vehicle and having an exterior field of view, wherein said object detection sensor comprises a camera disposed at the subject vehicle and having a field of view forward of the subject vehicle;
a control disposed at the subject vehicle and operable to process image data captured by said object detection sensor to detect an object exterior of the subject vehicle;
wherein said driver assist system is operable to (i) adjust said processing of said image data to a distance mode responsive to the subject vehicle traveling along a highway, and wherein, when processing said data in said distant mode, said driver assist system is operable to detect an object approaching the subject vehicle from a first distance from the subject vehicle near the effective range of said object detection sensor, (ii) adjust said processing of said image data to a side object detection mode responsive to the subject vehicle being parked at a side of a road, and (iii) adjust said processing of said image data to a nearby mode responsive to the subject vehicle traveling along a city road, and wherein, when processing said data in said nearby mode, said object detection sensor detects an object of interest at a second distance from the subject vehicle and approaching the subject vehicle as the subject vehicle travels along a road;
wherein said first distance is greater than said second distance and wherein, when processing said data in said nearby mode, said control does not process data to detect objects at the first distance from the subject vehicle; and
wherein, responsive to said processing of said image data, at least one of (a) an alert is operable to alert the driver of the subject vehicle of a potential hazard and (b) a system of the subject vehicle is operable to control a vehicle function to mitigate or avoid a potential hazard condition; and
wherein said driver assist system is operable to alert the driver of the subject vehicle to not open a vehicle door when the subject vehicle is parked and when said system detects another vehicle approaching the subject vehicle in a side lane adjacent to the subject vehicle.
