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. A control is disposed at the vehicle and includes a data processor. The imaging sensors are connected to the 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 at the data processor and (ii) power to the respective imaging sensor. The vehicular vision system utilizes at least one of (i) an ETHERNET communication protocol, (ii) a Gigabit Multimedia Serial Link (GMSL) protocol and (iii) a FPD-Link III protocol. Each of the single core coaxial cables provides bidirectional communication between the control and the respective imaging sensor.
