Vehicular vision system using image data transmission and power supply via a coaxial cable

A vehicular vision system, said vehicular vision system comprising:

• a front camera disposed at a vehicle equipped with said vehicular vision system;
• said front camera comprising a CMOS imaging sensor operable to capture image data;
• wherein said front camera is disposed at a windshield of the equipped vehicle and views forward through the windshield of the equipped vehicle;
• an electronic control unit (ECU) disposed at the equipped vehicle and comprising (i) a data processor and (ii) a DC power supply;
• wherein a coaxial cable carries DC power from the DC power supply of the ECU to said front camera;
• wherein image data captured by said front camera is conveyed from said front camera to the ECU via the coaxial cable;
• wherein image data captured by said front camera is conveyed via the coaxial cable at a data transmission rate of at least 1.6 Gbps;
• wherein calibration data is conveyed from said front camera to the ECU via the coaxial cable;
• wherein said front camera is in bidirectional communication with the ECU via the coaxial cable;
• wherein said front camera comprises a data serializer and the ECU comprises a data deserializer;
• wherein a rear-viewing camera is disposed at the equipped vehicle;
• wherein said rear-viewing camera views at least rearward of the equipped vehicle;
• wherein said rear-viewing camera comprising a CMOS imaging sensor operable to capture image data;
• wherein image data captured by said rear-viewing camera is conveyed from said rear-viewing camera to the ECU via another coaxial cable connecting said rear-viewing camera with the ECU;
• wherein said rear-viewing camera is in bidirectional communication with the ECU over the other coaxial cable connecting said rear-viewing camera with the ECU;
• wherein the other coaxial cable commonly carries (i) image data captured by said rear-viewing camera to the ECU for processing at the data processor of the ECU and (ii) DC power from the DC power supply of the ECU to said rear-viewing camera;
• wherein said rear-viewing camera comprises a data serializer and the ECU comprises another data deserializer;
• wherein image data captured by said rear-viewing camera is serialized at the data serializer and is conveyed to the ECU via the other coaxial cable connecting said rear-viewing camera with the ECU and is deserialized at the ECU by the other data deserializer;
• and
• wherein said vehicular vision system, responsive to processing at the data processor of the ECU of image data captured by said front camera and conveyed to the ECU via the coaxial cable, generates an output for a headlamp control system of the equipped vehicle.
