Abstract

A vehicle control system and method employs a sensing system and a controller. The sensing system is disposed on a host vehicle and configured to sense a visual condition of a driver of the host vehicle. The controller is configured to control an autonomous vehicle control system on board the host vehicle to stop the host vehicle at a stopping location based on the visual condition and at least one point of interest external to the host vehicle.

First claim

What is claimed is:

1. A vehicle control system comprising:
a sensing system disposed on a host vehicle and configured to sense an eye location of an eye of driver of the host vehicle within a passenger compartment of the host vehicle; and
a controller configured to estimate a field of view of the driver based on the eye location, determine whether a point of interest external to the host vehicle is expected to reside within the field of view of the driver at an expected stopping location of the host vehicle based on the eye location and a location of the point of interest, control an autonomous vehicle control system on board the host vehicle to stop the host vehicle at the expected stopping location upon determining that the point of interest is expected to reside within the field of view of the driver at the expected stopping location, and control the autonomous vehicle control system to stop the host vehicle at an adjusted stopping location that is different from the expected stopping location upon determining that the point of interest is expected to reside outside the field of view of the driver at the expected stopping location.

2. The vehicle control system according to claim 1 , wherein
the controller is configured to determine the adjusted stopping location as a location at which the controller determines that the point of interest is expected to reside within the field of view of the driver.

3. The vehicle control system according to claim 1 , wherein
the controller is further configured to determine the adjusted stopping location as a location at which the controller determines at least one of the following:
a visual system on board the host vehicle is expected to present to the driver an image representing the point of interest; and
the point of interest is expected to reside within the field of view of the driver.

4. The vehicle control system according to claim 3 , wherein
the visual system includes at least one of a visual display and a mirror.

5. The vehicle control system according to claim 1 , wherein
the controller is further configured to determine the adjusted stopping location based on a traveling condition of the host vehicle.

6. The vehicle control system according to claim 1 , wherein
the point of interest corresponds to a location of a traffic device.

7. The vehicle control system according to claim 1 , wherein
the controller is further configured to control the autonomous vehicle control system on board the host vehicle to stop the host vehicle at the expected stopping location based on the eye location and respective locations of a plurality of additional points of interest upon determining that the point of interest and all of the additional points of interests are expected to reside within the field of view of the driver at the expected stopping location.

8. The vehicle control system according to claim 7 , wherein
the controller is further configured to control the autonomous vehicle control system to stop the host vehicle at the adjusted stopping location upon determining that any of the additional points of interest is expected to reside outside the field of view of the driver at the expected stopping location.

9. The vehicle control system according to claim 8 , wherein
the controller is configured to determine the adjusted stopping location as a location at which a visual system on board the host vehicle is expected to present to the driver an image representing a first group of the additional points of interest while a second group of the additional points of interest is expected to reside within the field of view of the driver.

10. The vehicle control system according to claim 1 , wherein
the sensing system is further configured to sense at least one operating condition of the host vehicle; and
the controller is further configured to control the autonomous vehicle control system to stop the host vehicle at the expected location based on the eye location, the point of interest and the at least one operating condition.

11. The vehicle control system according to claim 10 , wherein
the at least one operating condition includes at least one of a speed and a steering angle of the host vehicle.

12. The vehicle control system according to claim 1 , wherein
the sensing system is further configured to sense a location of at least one remote vehicle relative to a location of the host vehicle; and
the controller is further configured to control the autonomous vehicle control system to stop the host vehicle at the stopping location based on the visual condition eye location, the point of interest and the location of the at least one remote vehicle.

13. The vehicle control system according to claim 1 , wherein
the sensing system is further configured to sense a present location of the host vehicle; and
the controller is further configured to control the autonomous vehicle control system to stop the host vehicle at the stopping location based on the eye location, the point of interest and the present location of the host vehicle.

14. The vehicle control system according to claim 1 , wherein
the point of interest corresponds to a location of a remote vehicle.

15. The vehicle control system according to claim 1 , wherein
the point of interest corresponds to a location of a pedestrian.

16. The vehicle control system according to claim 1 , wherein
the point of interest corresponds to a location of a traffic sign.

17. The vehicle control system according to claim 1 , wherein
the point of interest corresponds to a location of a marking on a road upon which the host vehicle is travelling.
