Abstract:
A vision system for a vehicle includes an imaging sensor disposed at the vehicle and having an exterior field of view. A control is disposed at the vehicle and a coaxial cable is in communication between the imaging sensor and the control. The vision system communicates image data captured by the imaging sensor to the control and supplies power to the imaging sensor via the coaxial cable. The coaxial cable may include an inner core comprising copper, a dielectric medium, a foil screen, an outer conductor comprising copper, a separating layer and an outer sheath. When initially powering up the vision system, a transceiver of the imaging sensor may be tuned to an initial communication mode, which is suitable for communication with at least one of the control, a communication interface of the vision system and a display device of the vision system.
Abstract:
A vehicular vision system includes an electronic control unit (ECU) disposed at a vehicle and a camera having a CMOS imaging sensor operable to capture image data. Image data captured by the camera is conveyed from the camera to the ECU via a 50 ohm coaxial cable. The camera is in bidirectional communication with the ECU over the 50 ohm coaxial cable. The 50 ohm coaxial cable commonly carries (i) image data captured by the camera for processing at a data processor of the ECU and (ii) power from a DC power supply of the ECU to the camera. Image data captured by the camera is serialized at a data serializer of the camera and is conveyed to the ECU via the 50 ohm coaxial cable and is deserialized at the ECU by a data deserializer of the ECU.
