Abstract: Example control methods and apparatus are described. One example control method includes obtaining, by a first controller, a first operating status of the first controller before a control function of the first controller and/or a control function of a second controller are/is activated. The first controller receives first indication information sent by the second controller, where the first indication information indicates a controller status of the second controller. The first controller sets a first controller mode of the first controller based on the first operating status and the first indication information. Second indication information is sent by the first controller to the second controller, so that a first controller mode of the second controller that is set by the second controller does not conflict with the first controller mode of the first controller.

Abstract: The present disclosure relates to control systems, clock synchronization methods, controllers, node devices, and vehicles. In one example control system provided in this application, a primary controller directly sends a reference clock signal to at least one node device by using a ring network, so that the at least one node device can perform timing based on a frequency of the reference clock signal.
