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. Each single core coaxial cable commonly carries (i) image data from the respective imaging sensor to the control for processing and (ii) power to the respective imaging sensor. Each imaging sensor is capable of communicating via a particular communication protocol. While each of the imaging sensors is in a respective initial mode and after the communication protocol is transmitted by the control to each of the imaging sensors, each of the imaging sensors communicates with the control in accordance with the communication protocol. Each of the single core coaxial cables provides bidirectional communication between the control and the respective imaging sensor.
