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.

Abstract: A vehicle control method implemented by a first vehicle configured with at least one driver assistance system. The method includes activating a driver assistance system to an active state, applying a vehicle speed range to the first vehicle in response to the driver assistance system being in the active state, obtaining first information of a moving object near the first vehicle, determining a first parameter based on the first information, and further terminating, based on the first parameter, the active state, and setting, based on the first parameter, the first vehicle to run at a first vehicle speed beyond the vehicle speed range.

Abstract: A vehicle lighting control method includes that a roadside communications device sends a first message to a vehicle. The first message prompts the vehicle to illuminate a first target, and the first target is near a travel path that the vehicle is to pass through. Before passing the first target, the vehicle adjusts the vehicle into a first lighting mode in advance based on the first message to illuminate the first target.
