Abstract:
A vehicular vision system includes an ECU disposed at a vehicle and a front camera having a CMOS imaging sensor operable to capture image data. Image data captured by the imaging sensor of the front camera is conveyed from the front camera to the ECU via a single core coaxial cable. The front camera is in bidirectional communication with the ECU over the single core coaxial cable. The single core coaxial cable commonly carries (i) image data captured by the imaging sensor for processing at a data processor of the ECU and (ii) power from a DC power supply of the ECU to the front camera. Image data captured by the imaging sensor is serialized at a data serializer of the front camera and is transmitted to the ECU via the single core coaxial cable and is deserialized at the ECU by a data deserializer of the ECU.
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.
