摘要： A method for determining a link state, and a device are provided to resolve a problem that a controller sends route update packets excessively frequently in a conventional link monitoring method. In the solution, a controller sends a first route update packet including a first route to a first forwarding device, so that the first forwarding device sends a third route update packet including a third route to at least one target forwarding device; a second forwarding device receives the third route update packet, determines a target link from the first forwarding device to the second forwarding device, and sends, based on a monitored state of the target link, a second route update packet including a second route and a target field to the controller; and the controller determines the state of the target link based on the target field in the second route update packet. Because the controller can determine the state of the target link by sending only the first route update packet to the first forwarding device, the method can greatly reduce a frequency of sending route update packets by the controller.

摘要： This application provides a control method and apparatus. The method may be applied to a controller in a vehicle. The controller may generate a packet, and send the packet to an electronic control unit. The packet includes a plurality of bits and control information. The plurality of bits may indicate whether the electronic control unit controls a plurality of objects (for example, actuators or functions) based on the control information. The plurality of bits are in a one-to-one correspondence with the plurality of objects. In this way, the electronic control unit associated with the plurality of objects can control the plurality of objects based on the control information. In this way, the plurality of objects of the vehicle can be controlled, information redundancy in the control packet of the vehicle can be effectively reduced, and transmission efficiency of the control packet of the vehicle can be effectively improved.

摘要： Embodiments of this application disclose a data transmission system, including an over the air OTA server, a master electronic control unit ECU, and a node ECU. The OTA server is configured to invoke a first interface of the master ECU. The master ECU is configured to obtain a size of a target software package in response to a fact that the OTA server invokes the first interface. The master ECU is further configured to invoke a second interface of the node ECU. The node ECU is configured to: in response to a fact that the master ECU invokes the second interface, obtain the size of the target software package and check remaining storage space of the node ECU, and when the remaining storage space is not less than the size of the target software package, receive the target software package sent by the OTA server. The solutions provided in this application may be applied to an intelligent vehicle, a connected vehicle, a new energy vehicle, and an autonomous driving vehicle. According to the solutions provided in this application, in a process of implementing in-vehicle software upgrade by using an OTA technology, dependence on a storage capability and a processing capability of the master ECU is reduced, and upgrade efficiency is improved.

摘要： A software version rollback method, apparatus, and system are provided, which can be applied to the field of intelligent vehicle. The method includes: obtaining a differential update package of target software (S301); updating a current version of the target software by using the differential update package, where the current version of the target software is updated from a first version to a second version (S302); and when there is a rollback requirement, performing rollback on the target software by using the differential update package, to roll back the current version of the target software to the first version (S303). When software version rollback is performed on the target software, a complete installation file of target software of an old version does not need to be re-downloaded from an update server, and the complete installation file of the target software of the old version does not need to be backed up. The differential update package of the target software may be directly used to roll back the target software, so as to roll back to the old version for running. In this way, timely software rollback can be implemented while occupancy of storage space of a vehicle is reduced.
