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

  • a plurality of cameras disposed at a vehicle equipped with said vision system;

    wherein said plurality of cameras comprises at least a first camera, a second camera, a third camera and a fourth camera;

    each of said first camera, said second camera, said third camera and said fourth camera having a respective field of view exterior of the equipped vehicle;

    each of said first camera, said second camera, said third camera and said fourth camera being operable to capture frames of image data;

    an electronic control unit (ECU);

    wherein image data captured by said first camera is provided to the ECU via a first ETHERNET link from said first camera to the ECU;

    wherein image data captured by said second camera is provided to the ECU via a second ETHERNET link from said second camera to the ECU;

    wherein image data captured by said third camera is provided to the ECU via a third ETHERNET link from said third camera to the ECU;

    wherein image data captured by said fourth camera is provided to the ECU via a fourth ETHERNET link from said fourth camera to the ECU;

    wherein at least one control signal is provided from the ECU to said first camera via said first ETHERNET link;

    wherein at least one control signal is provided from the ECU to said second camera via said second ETHERNET link;

    wherein at least one control signal is provided from the ECU to said third camera via said third ETHERNET link;

    wherein at least one control signal is provided from the ECU to said fourth camera via said fourth ETHERNET link;

    wherein first camera calibration data is provided from said first camera to the ECU via said first ETHERNET link;

    wherein second camera calibration data is provided from said second camera to the ECU via said second ETHERNET link;

    wherein third camera calibration data is provided from said third camera to the ECU via said third ETHERNET link;

    wherein fourth camera calibration data is provided from said fourth camera to the ECU via said fourth ETHERNET link;

    wherein said first camera is disposed at a front portion of the equipped vehicle, and wherein said second camera is disposed at a driver-side side portion of the equipped vehicle, and wherein said third camera is disposed at a passenger-side side portion of the equipped vehicle, and wherein said fourth camera is disposed at a rear portion of the equipped vehicle;

    wherein image data captured by at least one of said first camera, said second camera, said third camera and said fourth camera is processed at the ECU to detect an object present exterior of the equipped vehicle;

    wherein the object present exterior of the equipped vehicle is exterior a side of the equipped vehicle;

    wherein the object present exterior the side of the equipped vehicle comprises a vehicle that is approaching the equipped vehicle; and

    wherein the vehicle that is approaching the equipped vehicle is traveling in a traffic lane adjacent to a traffic lane in which the equipped vehicle is traveling.
