1. An imaging system for a vehicle, said imaging system comprising:

  • an imaging sensor, wherein said imaging sensor comprises a two-dimensional array of light sensing photosensor elements, and wherein said imaging sensor has a rearward field of view when mounted at a vehicle equipped with said imaging system;

    a display device comprising a video display screen for displaying images representative of image data captured by said imaging sensor;

    wherein, responsive to a driver of the equipped vehicle shifting the equipped vehicle to a reverse gear to commence a backup maneuver, said imaging system electronically generates an overlay that is electronically superimposed on said displayed images to assist the driver of the equipped vehicle when executing the backup maneuver, said overlay comprising first, second and third overlay zones;

    wherein said first overlay zone is indicative of a first distance range from the rear of the equipped vehicle to a first distance from the rear of the equipped vehicle as displayed at said video display screen;

    wherein said second overlay zone is indicative of a second distance range from the first distance to a second distance from the rear of the equipped vehicle as displayed at said video display screen;

    wherein said third overlay zone is indicative of a third distance range beyond the second distance from the rear of the equipped vehicle as displayed at said video display screen;

    wherein, as indicated to the driver viewing said video display screen when executing a backup maneuver, the first distance is closer to the rear of the equipped vehicle than the second distance and the second distance is closer to the rear of the equipped vehicle than the third distance;

    wherein said first overlay zone comprises a first color and said second overlay zone comprises a second color and said third overlay zone comprises a third color;

    wherein said first color is a different color than said second color and said second color is a different color than said third color;

    wherein, after the backup maneuver is completed by the driver, said overlay is no longer electronically generated by said imaging system;

    wherein said imaging system, operating in conjunction with an object detection system of the equipped vehicle operable for detecting objects in the path of the equipped vehicle when the equipped vehicle is reversing, is operable to detect an object being approached by the equipped vehicle as it reverses;

    wherein, when the object detection system detects an object in the path of and being approached by the equipped vehicle as it reverses and determines that the detected object is within the third distance range, said imaging system adjusts said third overlay zone to alert the driver of the equipped vehicle of the presence of the detected object within said third overlay zone;

    wherein, when the object detection system determines that the detected object is within the second distance range, said imaging system adjusts said second overlay zone to alert the driver of the equipped vehicle of the presence of the detected object within said second overlay zone;

    wherein, when the object detection system determines that the detected object is within the first distance range, said imaging system adjusts said first overlay zone to alert the driver of the equipped vehicle of the presence of the detected object within said first overlay zone; and

    wherein said object detection system comprises at least one of (i) an ultrasonic sensing system, (ii) a lidar sensing system, (iii) a radar sensing system and (iv) image processing of image data captured by said imaging sensor.
