1. A driver assistance system for a vehicle, said driver assistance system comprising:

  • a forward facing camera having a field of view that encompasses the road ahead of the equipped vehicle;

    said forward facing camera comprising a CMOS imaging sensor;

    a control disposed at or in the equipped vehicle and comprising an image processor;

    wherein image data captured by said forward facing camera is processed by said image processor;

    wherein said image processor processes data at a processing speed of at least about 5 MIPS;

    wherein said control, responsive to processing by said image processor of image data captured by said forward facing camera, determines a surface condition of the road being traveled by the equipped vehicle;

    wherein said control, responsive to processing by said image processor of image data captured by said forward facing camera, detects at least one of solid lines, dashed lines and double lines on the road being traveled by the equipped vehicle;

    wherein, at least in part responsive to processing by said image processor of image data captured by said forward facing camera, said control is operable to determine a potential inappropriate lane change maneuver of the equipped vehicle;

    wherein, at least in part responsive to processing by said image processor of image data captured by said forward facing camera, said control is operable to determine a potential impact with another vehicle;

    wherein said control receives vehicle data relating to the equipped vehicle via a vehicle bus of the equipped vehicle, said vehicle data including vehicle speed and vehicle steering angle;

    wherein said image processor processes image data captured by said forward facing camera to detect a traffic control device present within the field of view of said forward facing camera;

    wherein, responsive at least in part to processing of captured image data by said image processor, said control determines a traffic control status of the detected traffic control device; and

    wherein, responsive at least in part to processing of captured image data by said image processor to determine the surface condition of the road being traveled by the equipped vehicle, said control determines when the determined traffic control status of the detected traffic control device requires at least one of (i) a reduction of speed of the equipped vehicle and (ii) that the equipped vehicle come to a stop.
