1. A vehicular vision system, said vehicular vision system comprising:

  • a plurality of imaging sensors disposed at a vehicle and having respective exterior fields of view, each of said imaging sensors capturing respective image data;

    a control disposed at the vehicle, the control comprising a data processor;

    wherein said imaging sensors are connected to said control via respective ones of a plurality of single core coaxial cables;

    wherein each said single core coaxial cable commonly carries (i) image data from the respective imaging sensor to the control for processing at the data processor and (ii) power to the respective imaging sensor;

    wherein each of said imaging sensors is capable of communicating via any one of (i) an ETHERNET communication protocol, (ii) a Gigabit Multimedia Serial Link (GMSL) protocol and (iii) a FPD-Link III protocol;

    wherein said vehicular vision system utilizes a chosen communication protocol selected from the group consisting of (i) the ETHERNET communication protocol, (ii) the Gigabit Multimedia Serial Link (GMSL) protocol and (iii) the FPD-Link III protocol;

    wherein, when initially powering up said vehicular vision system, each of said imaging sensors is in an initial mode and, while in the initial mode, each of said imaging sensors receives the chosen communication protocol so as to communicate with said control in accordance with the chosen communication protocol; and

    wherein each of said single core coaxial cables provides bidirectional communication between said control and the respective imaging sensor.
