Abstract

A driver assistance system for a vehicle includes at least one sensor including an image sensor operable to capture image data. An image processor is operable to process captured image data to determine at least one of (i) a driving condition of the vehicle and (ii) a road condition of the road that the vehicle is traveling along. The driver assistance system, when activated and at least in part responsive to image processing of captured image data, is operable to control at least one accessory or system of the vehicle. The driver assistance system is operable to adjust at least one parameter of the control of the at least one accessory or system of the vehicle in response to (i) an identification of a particular driver and (ii) at least one preferred parameter indicative of the driver'"'"'s preference for the at least one accessory or system of the vehicle.

4. The driver assistance system of claim 3, wherein said at least one preferred parameter comprises a threshold level at which an alert is generated or at which a steering adjustment is made as the vehicle moves towards a lane marker or out of a lane in which the equipped vehicle is traveling.

5. The driver assistance system of claim 1, wherein said at least one preferred parameter comprises a plurality of preferred parameters, and wherein said driver assistance system selects an appropriate one of said plurality of preferred parameters responsive to the determined driving condition of the equipped vehicle.

6. The driver assistance system of claim 5, wherein the determined driving condition comprises one of a daytime driving condition and a nighttime driving condition.

7. The driver assistance system of claim 5, wherein the determined driving condition comprises one of a dry driving condition, a rain driving condition and a snow driving condition.

8. The driver assistance system of claim 1, wherein said image sensor comprises a forward viewing image sensor viewing forward of the equipped vehicle.

9. The driver assistance system of claim 8, wherein said forward viewing image sensor is disposed at or near a windshield of the equipped vehicle and views through the windshield and forwardly in the direction of forward travel of the equipped vehicle.
