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

  • a central processor;

    at least one image capture device operable to capture image data;

    at least a first data processor operable to preprocess said image data;

    at least one non-image sensor operable to capture non-image data;

    at least a second data processor operable to process said non-image data;

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

    said second data processor preprocessing said non-image data captured by said at least one non-image sensor to preprocessed second data having reduced bandwidth requirement relative to said non-image data captured by said at least one non-image sensor, said preprocessed second data being formatted into a standard data format and transmitted to said central processor via at least one of a wired link and a wireless link;

    said central processor processing the transmitted preprocessed first data and the transmitted preprocessed second 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 subject vehicle, and (b) a stoplight or a sign in front of the subject vehicle; and

    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 non-image data captured by said at least one non-image sensor comprises high resolution data and wherein said high resolution data is preprocessed by at least one of said first and second data processors in a manner that reduces bandwidth requirements.
