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

  • a vision system comprising a first camera disposed at a vehicle equipped with said driver assistance system, said first camera having a field of view forward of the equipped vehicle that encompasses a road being traveled along by the equipped vehicle;

    wherein the road has at least three lanes comprising (i) a first lane along which the vehicle is traveling, (ii) a second lane immediately adjacent the first lane, and (iii) a third lane immediately adjacent the second lane at the opposite side of the second lane from the first lane;

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

    wherein said data processor comprises an image processor;

    wherein image data captured by said first camera is provided to said control and is processed by said image processor;

    wherein said data processor processes data at a processing speed of at least 30 MIPS;

    wherein, responsive to processing by said image processor of image data captured by said first camera, lane markers on the road being traveled along by the equipped vehicle are detected;

    wherein, responsive to processing by said image processor of image data captured by said first camera, said control determines the first, second and third lanes of the road being traveled by the equipped vehicle;

    a sensing system operable to detect other vehicles present exterior the equipped vehicle;

    wherein said sensing system comprises a second camera disposed at the equipped vehicle and having a field of view at least rearward and sideward of the equipped vehicle as the equipped vehicle travels along the road;

    wherein said sensing system further comprises a radar sensor disposed at the equipped vehicle and having a field of sensing at least rearward and sideward of the equipped vehicle as the equipped vehicle travels along the road;

    wherein image data captured by said second camera is provided to said control;

    wherein radar data generated by said radar sensor is provided to said control;

    wherein said control receives vehicle data relating to the equipped vehicle via a vehicle bus of the equipped vehicle;

    wherein, responsive at least in part to processing at said data processor of radar data generated by said radar sensor and of image data captured by said second camera, said control detects another vehicle present on the road being traveled along by the equipped vehicle and approaching the equipped vehicle from its rear;

    wherein, with the equipped vehicle traveling along the first lane, and responsive at least in part to processing at said data processor of radar data generated by said radar sensor and of image data captured by said second camera, said control determines that the other vehicle is travelling in a next but one lane to the lane the second lane or in the third lane of the road along which the equipped vehicle is travelling;

    wherein, responsive to determination that the other vehicle is approaching the equipped vehicle and is traveling in the second lane, and responsive to said control detecting a lane change maneuver of the equipped vehicle toward the second lane, said control generates an alert that a lane change by the equipped vehicle from the first lane to the second lane is not safe; and

    wherein, responsive to determination that the other vehicle is approaching the equipped vehicle and is traveling in the third lane, and responsive to said control detecting a lane change maneuver of the equipped vehicle toward the second lane, said control determines that a lane change from the first lane to the second lane can proceed without hazard of impact with the other vehicle detected travelling in the third lane.
