US Patent 10560610 Method of synchronizing multiple vehicular cameras with an ECU

A method of synchronizing cameras with an electronic control unit (ECU) of a vehicular vision system includes providing camera control signals to the cameras from the ECU via respective links from the ECU to the cameras, with the camera control signals regulating timing of the respective camera to be synchronous with reference timing of the ECU. The timing regulation of the cameras includes starting the camera synchronous to the ECU reference timing and holding the camera synchronous to the ECU reference timing. Image data is captured with each camera and provided to the ECU via the respective link. Image data captured by at least one of the cameras may be processed to detect an object present exterior of the vehicle.
