Abstract
A method of synchronizing cameras for a vehicular vision system includes providing camera control signals to the cameras from the ECU via respective links from the ECU to the cameras. At least two of the cameras are in communication with a hub via respective links, and the ECU is in communication with the hub via a hub link. The camera control signals are provided to one camera via a link between the ECU and the camera, and are provided to at least two other cameras via the hub link and respective links between the hub and the other cameras. The camera control signals regulate timing of the respective camera via starting the camera synchronous to the ECU reference timing. Image data is captured by each camera and provided to the ECU via the respective link or links.
