Abstract: A redundant electronic control system includes a control unit, a first output component, and a second output component. The control unit may generate a first execution signal and a second execution signal. The control unit controls the first output component to output the first execution signal to a first actuator, and controls the second output component to output the second execution signal to a second actuator. When the first output component fails, the control unit may control the second output component to output the first execution signal to the first actuator. When the second output component fails, the control unit may control the first output component to output the second execution signal to the second actuator.

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.
