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

  • a front camera disposed at a front portion of a vehicle equipped with said vehicular control system;

    said front camera comprising an imaging sensor comprising an array of a plurality of photosensor elements arranged in multiple columns and multiple rows, the imaging sensor of said front camera having a forward field of view exterior of the equipped vehicle and operable to capture image data;

    wherein said front camera comprises a first low-voltage differential signaling (LVDS) serializer;

    a rear camera disposed at a rear portion of the equipped vehicle;

    said rear camera comprising an imaging sensor comprising an array of a plurality of photosensor elements arranged in multiple columns and multiple rows, the imaging sensor of said rear camera having a rearward field of view exterior of the equipped vehicle and operable to capture image data;

    wherein said rear camera comprises a second LVDS serializer;

    an electronic control unit (ECU);

    wherein said ECU comprises (i) a first LVDS de-serializer, (ii) a second LVDS de-serializer, (iii) an electrical power source and (iv) an image processor;

    wherein said front camera connects with said ECU via a first coaxial cable;

    wherein said rear camera connects with said ECU via a second coaxial cable;

    wherein image data captured by the imaging sensor of said front camera is converted at said first LVDS serializer to a first image signal and is carried to said ECU via said first coaxial cable;

    wherein image data captured by the imaging sensor of said rear camera is converted at said second LVDS serializer to a second image signal and is carried to said ECU via said second coaxial cable;

    wherein said first image signal is de-serialized at said first LVDS de-serializer of said ECU;

    wherein said second image signal is de-serialized at said second LVDS de-serializer of said ECU; and

    wherein at least one selected from the group consisting of;

    (i) said image processor of said ECU is operable to process the de-serialized first image signal to detect a vehicle present in the forward field of view of said front camera, and wherein, responsive at least in part to processing at said image processor of the de-serialized first image signal and to determination by said vehicular control system that the equipped vehicle and the detected vehicle may collide, said vehicular control system, at least in part, controls a braking system of the equipped vehicle; and

    (ii) said image processor of said ECU is operable to process the de-serialized second image signal to detect objects present in the rearward field of view of said rear camera, and wherein, responsive at least in part to processing at said image processor of the de-serialized second image signal, an object present rearward of the equipped vehicle is detected.
