Abstract
A vehicular multi-camera surround view system includes a plurality of cameras disposed at a vehicle and having respective exterior fields of view, each of the cameras capturing respective image data. The cameras are connected to an ECU via respective ones of a plurality of single core coaxial cables. The ECU is disposed at the vehicle and includes (i) a data processor and (ii) a DC power supply. Each of the cameras is in full duplex bidirectional communication with the ECU over the respective single core coaxial cable. Each single core coaxial cable commonly carries (i) image data from the respective camera to the ECU for processing and (ii) power from the DC power supply of the ECU to the respective camera. The ECU combines image data conveyed by the cameras to form composite video images and outputs the composite video images to a display device having a video display screen.
