If the vehicle is parked in the parking garage, the light can be finally projected onto the ceiling of the parking garage when the light is projected to the position right above the vehicle by the projection device, so that a user can remotely observe the condition of the light projected in the parking garage to distinguish and determine the vehicle.

The method for searching the vehicle provided by the embodiment of the invention can control the projection device to project the light to the upper part of the vehicle, and can comprise the following steps:

acquiring an induction mode of a vehicle; the sensing mode may include an auto-sensing mode and a user-defined mode;

when the sensing mode is an automatic sensing mode, controlling the projection device to project lamplight above the vehicle;

when the sensing mode is a user-defined mode, receiving a vehicle finding instruction sent by the mobile terminal, and controlling the projection device to project light above the vehicle.

In the embodiment of the invention, when the vehicle controls the projection device to project light above the vehicle, the sensing mode of the vehicle can be acquired first. The sensing modes of the vehicle comprise an automatic sensing mode and a user-defined sensing mode, and the user can switch the automatic sensing mode and the user-defined mode on a screen in the vehicle and/or a portable mobile terminal. The automatic induction mode is that the vehicle automatically inducts and judges whether the mobile terminal carried by the user enters the sensing range of the vehicle, and the user does not need to send a vehicle finding instruction to the vehicle by operating the mobile terminal. The user-defined induction mode is that a user needs to send a vehicle finding instruction to the vehicle by operating the mobile terminal, and the vehicle judges whether the mobile terminal carried by the user enters the sensing range of the vehicle according to whether the vehicle finding instruction sent by the mobile terminal is received or not.

When the vehicle obtains that the sensing mode of the vehicle is an automatic sensing mode, when the mobile terminal carried by the user is sensed to enter the sensing range of the vehicle (for example, when the user is sensed to be 50 meters away from the vehicle (the 50 meters can be the maximum sensing distance)), the vehicle can wake up the projection device, so that the projection device projects light above the vehicle, the vehicle can be actively found by the aid of the projection device without opening a vehicle finding function by the user, and the vehicle finding efficiency and the vehicle finding experience of the user are improved.

When the vehicle obtains that the sensing mode of the vehicle is a user-defined mode (namely, the user closes the automatic sensing mode and opens the user-defined mode), the vehicle searching function can be opened by operating the mobile terminal when the user arrives at the parking lot to start searching the vehicle (namely, the mobile terminal carried by the user can send a vehicle searching instruction, and taking the mobile terminal as a smart phone as an example, the user can open the vehicle searching function on an app corresponding to the vehicle on the smart phone). When the mobile terminal carried by the user enters the sensing range of the vehicle, the vehicle can receive a vehicle finding instruction sent by the user through the mobile terminal, and then the vehicle can activate the projection device, so that the projection device can project light above the vehicle, the projection device is used for assisting the user in finding the vehicle under the condition that the user finds the vehicle, and the vehicle finding efficiency of the user is improved.

The method for searching the vehicle provided by the embodiment of the invention can control the projection device to project the light to the upper part of the vehicle, and can comprise the following steps:

the brightness and/or area of the light projected by the projection device to the upper side of the vehicle are/is controlled to be reduced along with the reduction of the distance between the movable end and the vehicle.

In the embodiment of the invention, when the vehicle controls the projection device to project light above the vehicle, the brightness and/or the area of the light projected by the projection device to the vehicle can be controlled to be reduced along with the reduction of the distance between the moving end and the vehicle, namely, when the moving end carried by the user enters the perception range of the vehicle, the brightness and/or the area of the light projected by the projection device and the distance between the moving end and the vehicle form a positive correlation, namely, when the moving end is positioned at the maximum perception distance of the vehicle, the brightness and/or the area of the light projected by the projection device are maximum.

Through the mode, a user can easily find and position the vehicle through the projection light with the maximum brightness and/or the projection light with the maximum area at the maximum perception distance, and the brightness and/or the area of the projection light can be gradually reduced along with the reduction of the distance between the user and the vehicle so as to reduce the electric consumption of the projection device, and the projection light is enabled to be more in accordance with the reading habit of the user so as to improve the vehicle finding experience of the user.

If the projection device can turn, the brightness and area of the projection light (i.e., the light projected onto the vehicle) corresponding to the maximum perceived distance of the projection device can be larger than the brightness and area of the projection light (i.e., the light projected onto the vehicle headlight) corresponding to the projection device when the auxiliary vehicle lamp is illuminated.

In the embodiment of the invention, when the sensing mode of the vehicle is a user-defined mode, the user can select the projection form on the mobile terminal, wherein the alternative projection form can specifically include a pattern projection form, a text projection form, a lamplight projection form and the like. The pattern projection form can be used for projecting patterns, the patterns are provided with patterns preset by a system, such as vehicle logo (the vehicle logo can be projected to facilitate the user to find the vehicle and improve the brand influence), and the user can select the patterns to upload and project; in the text projection form, the user can edit the text projection by himself; the light projection forms can comprise different light dynamic effects (light flicker frequency and the like) and different light colors. It should be noted that, in these several projection forms, the user can customize specific projection contents. Specifically, when the mobile terminal is smart equipment such as a smart phone, a user can customize a projection pattern style, a lamplight color, a lamplight flickering mode and the like on the smart equipment so as to meet diversified user requirements, make own vehicle projection lamplight different, and improve vehicle finding efficiency and vehicle finding experience. Or, the user can customize the projection pattern style, the lamplight color, the lamplight flickering mode and the like on the man-machine interaction interface of the vehicle, and then the user can select a specific projection mode on the mobile terminal.

After the user selects the cast form on the mobile terminal, the mobile terminal may transmit the cast form selected by the user to the vehicle. Wherein, the user can select one or more projection forms according to own requirements. Accordingly, the vehicle may receive the projected form sent by the mobile terminal. Then, when the vehicle is controlling the projection device to project light to the upper part of the vehicle, the projection device can be controlled to project light to the upper part of the vehicle according to the projection form received from the mobile terminal, so that personalized light projection is realized, a user can more accurately, quickly and efficiently find the vehicle, the interestingness of finding the vehicle can be improved, and the vehicle finding experience of the user is improved.

Further, after controlling the projector to project light upward of the vehicle in accordance with the projection pattern, the projection pattern may be changed if the user further wants to confirm the position of the vehicle itself, or if the user wants to increase the diversity of the vehicle projection, or the like. Specifically, the modified projection style may be sent to the vehicle by the mobile terminal, where the modified projection style may be selected by the user from the existing projection styles, or may be redefined by the user, and the present invention is not limited to this. Correspondingly, the vehicle receives the changed projection pattern sent by the mobile terminal and controls the projection device to project light to the upper side of the vehicle according to the changed projection pattern, so that the projection requirement of a user is met, and the projection diversity and the interest are improved.
