Abstract: An update method may include: obtaining a trip plan of a vehicle, where the trip plan includes a trip element; and sending a first update recommendation scheme corresponding to the trip plan, where the first update recommendation scheme indicates at least update information recommended to the vehicle. Thus, update recommendation can be actively implemented from a perspective of a trip. Based on a trip element of a user, different update information can be recommended based on different user trips.

Abstract: An upgrade method, an apparatus, and a system are provided, and relate to the field of internet of vehicles technologies. The method includes: obtaining status information of a terminal device, where the status information includes an identification result of a first user and/or an identification result of a second user, the first user is an owner of the terminal device, and the second user is an authorized user of the terminal device; and performing an upgrade operation of the terminal device based on the status information. The method helps flexibly implement an OTA upgrade process of the terminal device in a multi-user scenario, and ensures use experience of different users.

Abstract: A light projection apparatus includes an information obtaining module, a processing module, and a projection module. The information obtaining module is configured to obtain environment information and status information of a first object. The processing module is configured to determine, based on the status information, that the first object is a potentially dangerous object; determine a potentially dangerous area of the first object; determine a to-be-projected area based on the potentially dangerous area and the environment information, where the to-be-projected area is an area in which there is no light projection and light projection is allowed; and determine whether the to-be-projected area is within a projection range of the projection module. In response to a first result determined by the processing module, the projection module performs light projection in the to-be-projected area, to prompt a potential danger caused by the first object.
