Abstract

A vision system of a vehicle includes a camera disposed at a vehicle and having a field of view exterior of the vehicle. The camera captures image data and outputs a low voltage differential signal (LVDS). The system includes an LVDS repeater that receives the LVDS signal output by the camera and outputs at least two LVDS outputs to respective receivers. Each of the at least two LVDS outputs is representative of the LVDS signal output by the camera. The receivers include a receiver of respective ones of at least two devices selected from the group consisting of (i) a vehicle head unit, (ii) a display device, (iii) an electronic control unit of the vehicle and (iv) an image processor for a driver assistance function.

Claims

1. A vision system of a vehicle, said vision system comprising:

wherein said receivers comprise a receiver of respective ones of at least two devices selected from the group consisting of (i) a vehicle head unit of the vehicle, (ii) a display device of the vehicle, (iii) an electronic control unit of the vehicle and (iv) an image processor for a driver assistance system of the vehicle.

2. The vision system of claim 1, wherein said LVDS repeater outputs a first LVDS output to a receiver of a vehicle head unit of the vehicle and outputs a second LVDS output to a receiver of an electronic control unit of the vehicle.

3. The vision system of claim 1, wherein said LVDS repeater outputs at least three LVDS outputs to respective ones of three receivers.

4. The vision system of claim 3, wherein said LVDS repeater outputs a first LVDS output to a vehicle head unit of the vehicle, outputs a second LVDS output to a first electronic control unit of the vehicle, and outputs a third LVDS output to a second electronic control unit of the vehicle.

5. The vision system of claim 3, wherein said LVDS repeater outputs a first LVDS output to a receiver of a vehicle head unit of the vehicle, outputs a second LVDS output to a receiver of an image processor for a driver assistance system of the vehicle, and outputs a third LVDS output to an electronic control unit of the vehicle.

6. The vision system of claim 1, wherein said LVDS repeater comprises (i) a de-serializer that deserializes the received LVDS signal output by said camera, (ii) a field-programmable gate array that receives a deserialized signal from the de-serializer and outputs at least two outputs, (iii) at least two serializers that each receive a respective one of the outputs from the field-programmable gate array and output the respective LVDS output to the respective receiver.

7. The vision system of claim 6, wherein the field-programmable gate array outputs at least two Mobile Industry Processor Interface (MIPI) outputs.

8. The vision system of claim 1, wherein said LVDS repeater comprises (i) a de-serializer that deserializes the received LVDS signal, (ii) at least two discrete LVDS repeaters that receive a respective deserialized signal from the de-serializer and that output a respective output, (iii) at least two serializers that each receive a respective output from a respective one of the LVDS repeaters and output the respective LVDS output to the respective receiver.

9. The vision system of claim 8, wherein the LVDS repeaters output respective Mobile Industry Processor Interface (MIPI) outputs.
