1. A vehicular control system, said vehicular control system comprising:

  • a forward viewing camera having a field of view forward of a vehicle equipped with said vehicular control system and in a direction of forward travel of the equipped vehicle, wherein said forward viewing camera is operable to capture image data;

    wherein said forward viewing camera is disposed at an in-cabin side of a windshield of the equipped vehicle, said forward viewing camera viewing forward of the equipped vehicle through the windshield of the equipped vehicle;

    an image processor operable to process image data captured by said forward viewing camera;

    wherein lane markers along a road along which the equipped vehicle is traveling are detected responsive to processing by said image processor of image data captured by said forward viewing camera;

    wherein road curvature of the road along which the equipped vehicle is traveling is determined responsive at least in part to processing by said image processor of image data captured by said forward viewing camera;

    wherein, responsive at least in part to processing by said image processor of image data captured by said forward viewing camera, a traffic lane of the road along which the equipped vehicle is traveling is determined;

    wherein, responsive at least in part to processing by said image processor of image data captured by said forward viewing camera, another vehicle present on the road along which the equipped vehicle is traveling and forward of the equipped vehicle is detected;

    wherein, responsive at least in part to processing by said image processor of image data captured by said forward viewing camera, said vehicular control system determines that the detected other vehicle is travelling in a traffic lane to the left of the determined traffic lane along which the equipped vehicle is traveling;

    wherein the equipped vehicle comprises a speed control system operable to control speed of the equipped vehicle;

    wherein the speed control system of the equipped vehicle controls speed of the equipped vehicle at least in part responsive to at least one selected from the group consisting of (a) processing by said image processor of image data captured by said forward viewing camera and (b) map data relevant to a current geographic location of the equipped vehicle; and

    wherein the detected other vehicle travelling in a traffic lane to the left of the determined traffic lane along which the equipped vehicle is traveling is determined to be not an oncoming other vehicle at least in part via processing by said image processor of image data captured by said forward viewing camera detecting illuminated taillights of the other vehicle.
