1. An object detection system suitable for use in a vehicle, said system comprising:

  • a central processor at a first location in or on a vehicle;

    at least one image capture device at a second location in or on the vehicle, said second location at a distance from said first location, said at least one image capture device comprising an image data processor;

    at least one radar sensor at a third location in or on the vehicle, said third location at a distance from said first location, said at least one radar sensor comprising a radar data processor;

    image data captured by said at least one image capture device preprocessed by said image data processor at said at least one image capture device to image data having reduced bandwidth requirement relative to the image data captured by said at least one image capture device and formatted into a standard data format and transmitted by at least one of a wired link and a wireless link to said central processor;

    radar data captured by said at least one radar device preprocessed by said radar data processor said at least one radar device to radar data having reduced bandwidth requirement relative to the radar data captured by said at least one radar sensor and formatted into a standard data format and transmitted by at least one of a wired link and a wireless link to said central processor;

    said central processor processing the transmitted image data and the transmitted radar data and generating an output indicative of an object external the vehicle, said object comprising at least one of;

    (a) another vehicle in front of, to the side or to the rear of the vehicle having said image capture device and said radar sensor, and (b) a stoplight or a sign in front of the vehicle having said image capture device and said radar sensor;

    said standard data format comprising a format that is operational on a vehicle bus network, wherein at least one chosen from (i) said image data captured by said image capture device and (ii) said radar data captured by said at least one radar device comprises high resolution data and wherein said high resolution data is preprocessed by at least one chosen from said image data processor and said radar data processor in a manner that reduces bandwidth requirements.
