A vehicular vision system includes a rearward-viewing camera and a forward-viewing camera disposed at a vehicle. Image data captured by the cameras is provided to the electronic control unit. The electronic control unit sends respective control data to the cameras, and the respective sent control data is stored in respective memory of the cameras. With the respective sent control data stored in the respective memory of the cameras, the electronic control unit sends a trigger signal to the cameras. Responsive to the sent trigger signal, the cameras load operational parameters of the respective stored control data into respective image sensors of the cameras so that the operational parameters of the respective image sensors of the cameras are synchronized. With the operational parameters of the respective image sensors of the cameras synchronized, image data is captured by the respective image sensors and is sent to the electronic control unit.

Multi-camera vehicle vision system with data synchronization

A vehicular vision system includes at least one color camera disposed at a vehicle and having an image sensor operable to capture image data. A first system on chip (SoC) includes an image signal processor that receives captured image data and converts the received image data to converted data that is in a format suitable for machine vision processing. A second system on chip (SoC) receives captured image data and communicates display data to a display disposed in the vehicle, with the display data being in a format suitable for display of video images at the display. At startup of the vehicle, video images derived from the display data are displayed by the display within a time period following startup of the vehicle and machine vision data processing of converted data does not commence until after the display time period has elapsed following startup of the vehicle.

Vehicle vision system with smart camera video output

A vehicular vision system includes a camera and a repeater element at a vehicle. The repeater element is powered at least in part via power-over-coax and includes a de-serializer, a repeater and at least two serializers. The camera captures image data and outputs a camera output that includes serialized image data. The camera output is received at the repeater element and is de-serialized via the de-serializer to generate a de-serialized output. The de-serialized output is provided to the repeater and at least two repeater outputs are provided to the serializers. The serializers serialize the received repeater outputs to generate respective serialized outputs. The serializers each output the respective serialized output to a respective receiver of the vehicle. Each of the serialized outputs is representative of the serialized image data of the camera output received from the camera.

Vehicular vision system that provides camera outputs to receivers using repeater element

A vehicular vision system includes a plurality of cameras disposed at a vehicle and having respective exterior fields of view. Each camera includes an image sensor and a microcontroller having memory, and each camera is in communication with a vehicle controller. Image data captured by the image sensor of each camera is communicated to the vehicle controller. The vehicle controller communicates control data to each camera, and the communicated control data is stored in memory of each camera. With the communicated control data stored in the memory of each camera, the vehicle controller communicates a trigger signal to each camera during operation of the vehicle and vision system. Responsive to the communicated trigger signal, the microcontroller of each camera loads parameters of the control data stored in the respective memory into the respective image sensor so that the parameters of the image sensors of all of the cameras are synchronized.

A vehicular vision system includes a rear backup vehicle camera, a trailer camera disposed at a rear of a trailer, a display device disposed in the vehicle, and an electronic control unit (ECU) disposed in the vehicle. With the trailer not hitched to the vehicle and during a reversing maneuver of the vehicle, the ECU generates video images derived at least in part from image data captured by the rear backup vehicle camera and the display device displays the video images. With the trailer hitched to the vehicle, image data captured by the trailer camera is provided to the vehicle via data communication over powerline using a DC powerline, and the display device displays the video images derived at least in part from image data captured by the trailer camera for viewing by the driver of the vehicle during the driving maneuver of the vehicle with the trailer hitched thereto.

A vision system for a vehicle includes at least one camera disposed at a vehicle and having an image sensor operable to capture image data. A display is operable to display video images for viewing by a driver of the vehicle during normal operation of the vehicle. A first system on chip (SoC) receives captured image data and processes the received captured image data for machine vision. The first SoC, responsive to image processing of the received captured image data, generates an output for a driver assistance system of the vehicle. A second system on chip (SoC) receives captured image data and communicates the image data to the display.

A vehicular multi-camera vision system includes a plurality of exterior viewing vehicle cameras disposed at a vehicle, a trailer camera disposed at a rear of a trailer and viewing rearward, an ECU and a display device in the vehicle. With the trailer not hitched to the vehicle and during a driving maneuver of the vehicle, image data captured by the vehicle cameras is provided to the ECU and the display device displays video images generated by the ECU and derived from image data captured by the vehicle cameras. With the trailer hitched to the vehicle and during a driving maneuver of the vehicle towing the trailer, image data captured by the trailer camera and the vehicle cameras is provided to the ECU and the display device displays video images generated by the ECU and derived from image data captured by the trailer camera and side viewing vehicle cameras.

A vehicular surround vision system includes a plurality of vehicular cameras disposed at a vehicle and having respective exterior fields of view, a trailer camera disposed at a rear of a trailer and having a rearward field of view, an ECU and a display device in the vehicle. With the trailer not hitched to the vehicle and during a driving maneuver of the vehicle, the display device displays surround view video images derived from image data captured by at least the rearward viewing and sideward viewing vehicular cameras and provided to the ECU. With the trailer hitched to the vehicle and during a driving maneuver of the vehicle and trailer, the display device displays surround view video images derived from image data captured by the trailer camera and provided to the ECU and image data captured by at least some of the vehicular cameras and provided to the ECU.

A method for providing outputs to receivers of a vehicular vision system includes disposing a camera at a vehicle and disposing an LVDS repeater device at the vehicle. The LVDS repeater device includes a de-serializer, a repeater and at least two serializers. The LVDS repeater device is powered at least in part via power-over-coax from a head unit or ECU of the vehicle. The camera captures image data and outputs an LVDS camera output. The LVDS camera output is received at the LVDS repeater device and is de-serialized via the de-serializer. The de-serialized LVDS camera output is provided to the repeater and at least two outputs are provided to the serializers and are serialized. The serializers each output a respective LVDS repeater output to a respective receiver of the vehicle. The receivers include a receiver of respective ones of the vehicle head unit and the ECU.
