Abstract: An information storage system and apparatus relate to the field of automatic control technologies in order to resolve a problem that there is little information for diagnosing a fault that is stored using a freeze frame. The system includes at least one subcontroller configured to obtain a parameter value corresponding to a parameter, and send the parameter and the parameter value corresponding to the parameter to a management controller, the management controller configured to send the received parameter and the received parameter value corresponding to the parameter to a vehicle-intelligent device, and the vehicle-intelligent device is configured to receive and store the parameter and the parameter value corresponding to the parameter, where each subcontroller is coupled to at least one executor, and the management controller is coupled to each subcontroller of the at least one subcontroller.
