Abstract

The application provides a control method of a vehicle-mounted projection device, the vehicle-mounted projection device and a vehicle. The method comprises the steps of obtaining vehicle state information when a starting button is triggered, prohibiting starting projection when the vehicle state meets driving conditions, sending prompt information to a vehicle machine, and starting projection if not. The vehicle-mounted projection equipment is connected with a vehicle, can actively acquire the vehicle state information, and judges whether the safety starting condition is met or not according to the vehicle state information when the starting key is triggered. When the vehicle is in a driving state, prompt information is sent to the vehicle machine, a driver is timely reminded of the fact that the vehicle-mounted projection equipment is touched by mistake, projection is started when the vehicle is not in the driving state, and the playing requirement of the vehicle-mounted projection equipment is met under the condition that driving safety is not affected.

Description

Control method of vehicle-mounted projection equipment, vehicle-mounted projection equipment and vehicle Technical Field The present application relates to the field of vehicle control technologies, and in particular, to a control method of a vehicle-mounted projection device, and a vehicle. Background With the large screen and intelligent demands of automobiles, part of factories introduce projectors onto automobiles, the projectors are fixed at two rows or three rows of seat headrest positions through brackets in a portable installation mode, when the automobile is used, an automobile owner needs to detach the projectors to place the projectors in a trunk, but in the actual use process, part of automobile owners need to detach the projectors for saving trouble and fix the projectors on the automobile, and the problem of false triggering of rear passengers is caused, for example, a child stands on a position to press a switch key by mistake, or an article or a body part touches the switch key by mistake. Under the condition of false touch, the projector can generate interference to a driver through glass reflection and refraction after being started, so that driving safety is affected. Disclosure of Invention The embodiment of the application provides a control method of vehicle-mounted projection equipment, the vehicle-mounted projection equipment and a vehicle, and aims to solve the problem that starting of the vehicle-mounted projection equipment affects driving safety. In a first aspect, an embodiment of the present application provides a method for controlling a vehicle-mounted projection device, including: when the starting key is triggered, acquiring vehicle state information; And when the vehicle state meets the driving condition, prohibiting the projection starting, and sending prompt information to the vehicle, otherwise, starting the projection. In one possible implementation, the driving condition includes that the vehicle speed is greater than zero, or that the vehicle is in reverse, forward, motion or neutral gear at zero. In one possible implementation, after the starting projection, the method further includes: And transmitting linkage signals to the linkage device in a short-distance wireless communication mode, wherein the linkage device comprises one or more of a seat, an in-vehicle light, an in-vehicle fragrance device, a window shade, a vehicle window, a vehicle-mounted sound box and an in-vehicle air conditioner. In one possible implementation manner, the vehicle-mounted projection device is respectively connected with a seat controller, an in-vehicle light controller, an in-vehicle fragrance device controller, a window shade controller, a vehicle window controller, an in-vehicle sound controller and an in-vehicle air conditioner controller.
