Abstract

A vehicular vision system includes a plurality of imaging sensors disposed at a vehicle and having respective exterior fields of view, each of the imaging sensors capturing respective image data. The imaging sensors are connected to a control via respective ones of a plurality of single core coaxial cables. The control is disposed at the vehicle and includes (i) a data processor and (ii) a DC power supply. Each single core coaxial cable commonly carries (i) image data from the respective imaging sensor to the control for processing and (ii) power from the DC power supply of the control to the respective imaging sensor. Each of the imaging sensors is in bidirectional communication with the control over the respective single core coaxial cable, with signal attenuation being below 100 dB at a frequency of 1 GHz per 100 m length of the respective single core coaxial cable.
