摘要： An information storage system and apparatus relate to the field of automatic control technologies, so as to resolve a problem in the prior art that there is little information that is used for diagnosing a fault and that is stored by 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 unit, and the vehicle-intelligent unit configured to: receive and store the parameter and the parameter value corresponding to the parameter, where each subcontroller is connected to at least one executor, and the management controller is connected to each subcontroller of the subcontroller. In this technical solution, when a fault is detected, a parameter corresponding to the fault and a parameter value corresponding to the parameter can be stored, and for the parameter, a parameter type and a parameter quantity are not limited. Therefore, compared with the prior art, relatively comprehensive information can be stored.

摘要： This application provides an in-vehicle gateway communication method, an in-vehicle gateway, and an intelligent vehicle. When receiving a first message from a first in-vehicle device, the in-vehicle gateway identifies identification information in the first message, and matches the identification information with preset identification information stored in the in-vehicle gateway, and only when the matching succeeds, the in-vehicle gateway sends a second message, to indicate, by using the second message, a second in-vehicle device to perform a target operation. However, when the identification information in the first message cannot match the preset identification information stored in the gateway, the in-vehicle gateway does not send the second information to control the second in-vehicle device to perform the target operation. Therefore, in this application, identification information of a first message is set in an in-vehicle gateway of a vehicle. This reduces a security threat to an in-vehicle network, and improves security performance of an in-vehicle network of a vehicle.

摘要： A terminal wakeup method and an apparatus are disclosed. The method includes: if an access point fails to send a data frame to a station, and the access point always fails to send a data frame to the station after channel switching, sending, by the access point, a wakeup signal to the station to wake up the station. According to the method, a data frame loss caused by channel switching can be reduced.

摘要： This application provides a data transmission method and an apparatus, applied to an intelligent vehicle, and a connected vehicle, to select an appropriate protection policy for to-be-transmitted data, and balance calculation resources of ECUs. The method includes: A first ECU obtains to-be-sent data. The first ECU determines a protection policy corresponding to the to-be-sent data from a plurality of protection policies, where the plurality of protection policies include a plurality of different encapsulation manners for the to-be-sent data, and the plurality of protection policies include at least two protection policies with different calculation amounts for processing the to-be-sent data. The first ECU encapsulates the to-be-sent data according to the protection policy corresponding to the to-be-sent data, to obtain an encapsulated packet. The first ECU sends the encapsulated packet to a second ECU, where the first ECU and the second ECU are any two ECUs in a vehicle.
