Abstract

A vision system for a vehicle includes a plurality of imaging sensors disposed at the vehicle and having respective exterior fields of view, with each of the imaging sensors capturing image data. The imaging sensors are connected to a control via respective ones of a plurality of single core coaxial cables. Each single core coaxial cable commonly carries (i) image data from the respective imaging sensor, (ii) power to the respective imaging sensor and (iii) communication data. Each of the imaging sensors is operable to transmit calibration data to the control. Each of the imaging sensors transmits calibration data when the respective imaging sensor is triggered to transmit calibration data. The vision system, responsive to receipt of calibration data by the control, is operable to identify the respective one of the imaging sensors transmitting the received calibration data.
