1. A vehicular lane change system, said vehicular lane change system comprising:

  • a forward-viewing camera disposed at an in-cabin side of a windshield of a vehicle equipped with said vehicular lane change system, said forward-viewing camera viewing through the windshield to capture image data at least forward of the equipped vehicle;

    a radar sensor disposed at the equipped vehicle, wherein said radar sensor has a field of sensing exterior of the equipped vehicle and wherein said radar sensor captures radar data;

    said forward-viewing camera having a field of view that encompasses a road being traveled along by the equipped vehicle;

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

    said data processor comprising an image processor;

    wherein image data captured by said forward-viewing camera is provided to said control and is processed by said image processor;

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

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

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

    wherein, responsive at least in part to image processing by said image processor of provided image data captured by said forward-viewing camera, said control determines lane edges of a lane being traveled by the equipped vehicle;

    wherein said control is operable to detect a lane change maneuver by a driver of the equipped vehicle to a lane immediately adjacent to the lane being traveled by the equipped vehicle;

    wherein detection by said control of the lane change maneuver by the driver of the equipped vehicle is based at least in part on determining, via image processing by said image processor of provided image data captured by said forward-viewing camera, that the equipped vehicle is approaching a determined lane edge of the lane being traveled by the equipped vehicle to cross that determined lane edge of the lane being traveled by the equipped vehicle;

    wherein detection by said control of the lane change maneuver by the driver of the equipped vehicle is irrespective of activation by the driver of the equipped vehicle of a turn signal indicator of the equipped vehicle;

    wherein, responsive to said control detecting the lane change maneuver by the driver of the equipped vehicle to the lane immediately adjacent to the lane being traveled by the equipped vehicle when the driver of the equipped vehicle has neglected to turn on an appropriate turn signal indicator of the equipped vehicle, said control automatically turns on the turn signal indicator at the appropriate side of the equipped vehicle;

    wherein, responsive at least in part to processing at said control of provided radar data captured by said radar sensor, said control detects another vehicle present in the lane immediately adjacent to the lane being traveled by the equipped vehicle; and

    wherein, responsive to detection by said control of the lane change maneuver by the driver of the equipped vehicle to the lane immediately adjacent to the lane being traveled by the equipped vehicle, and responsive to detection by said control of the other vehicle present in that lane immediately adjacent to the lane being traveled by the equipped vehicle, said vehicular lane change system generates an alert to the driver of the equipped vehicle.
