Multi-camera vehicular vision system

A vehicular vision system, said vehicular vision system comprising:

• a plurality of cameras disposed at a vehicle equipped with said vehicular vision system, each viewing exterior of the equipped vehicle;
• said plurality of cameras comprising a forward viewing camera disposed at and viewing at least forward through a windshield of the equipped vehicle, said forward viewing camera comprising an imaging sensor having a plurality of photosensor elements arranged in an array of multiple columns and multiple rows, said forward viewing camera operable to capture image data;
• said plurality of cameras comprising a rear camera disposed at a rear portion of the equipped vehicle, said rear camera comprising an imaging sensor having a plurality of photosensor elements arranged in an array of multiple columns and multiple rows, said rear camera viewing at least rearward of the equipped vehicle and operable to capture image data, wherein said rear camera comprises a rear backup camera of the equipped vehicle;
• said forward viewing camera and said rear camera each comprising at least one selected from the group consisting of (i) a respective Low Voltage Differential Signaling (LVDS) chip and (ii) a respective Ethernet chip;
• a control disposed at the equipped vehicle, said control comprising an image processor, wherein said forward viewing camera communicates with said control via a first image data transfer channel, and wherein said rear camera communicates with said control via a second image data transfer channel;
• wherein image data captured by said forward viewing camera is communicated by the first image data transfer channel via a first coaxial cable;
• wherein image data captured by said rear camera is communicated by the second image data transfer channel via a second coaxial cable;
• wherein image data captured by said forward viewing camera and carried to said control by said first coaxial cable is processed at said image processor of said control for object detection;
• wherein image data captured by at least said rear camera of said plurality of cameras is processed at said image processor of said control to detect an object present rearward of the equipped vehicle;
• wherein said control is operable to process input from a radar sensor;
• wherein said control generates an output provided to a video display device of the equipped vehicle, said video display device comprising a video display screen viewable by a driver of the equipped vehicle;
• and
• wherein, during a reversing maneuver of the equipped vehicle, said video display screen displays video images of an area rearward the equipped vehicle derived from image data captured by said rear camera and carried to said control by said second coaxial cable.
