Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0052] With social progress and economic development, cars have entered families widely. Car headlights, also known as car headlamps, are an important part of cars. They are mainly used for lighting at night or in bad weather conditions and have a single function. With the development of the automobile industry, consumers have higher and higher requirements for the functions of car headlights.

[0053] In view of the above problems, based on this, the embodiments of the present application provide a screen projection method, device, electronic device and storage medium based on car headlights to enrich the functions of car headlights and improve the user experience, which is described below through embodiments.

[0054] To facilitate understanding of this embodiment, a method for projecting a screen based on a car headlight disclosed in the embodiment of this application is first described in detail. The method is applied to a vehicle-mounted central control device in a car, and the car is provided with a vehicle-mounted main control screen, such as Figure 1 As shown, the following steps S101-S103 are included:

[0055] S101: Responding to a first trigger operation of a user on a projection control on a main control screen in a vehicle to determine whether the vehicle is currently in a parked state.

[0056] In this embodiment, the vehicle main control screen is generally arranged in front of the main driving seat, and the driver can see the vehicle main control screen after sitting in the main driving seat. Specifically, the vehicle main control screen can be arranged in front of the middle of the main driving seat and the co-pilot seat, and the driver and the co-pilot can see the vehicle main control screen after sitting in the main driving seat and the co-pilot seat respectively.

[0057] Typically, the user is the driver, and the vehicle-mounted main control screen is generally a touch screen.

[0058] In a possible implementation manner, when executing step S101, the following steps S1011-S1012 may be specifically performed:

[0059] S1011: In response to the user's first click operation on the multi-screen interactive control in the vehicle main control screen, the DLP projection control is displayed in the vehicle main control screen.

[0060] In this embodiment, if Figure 2 As shown in FIG. 1 , the in-vehicle main control screen includes a content display area, a multi-screen interactive control, etc. After the user clicks the multi-screen interactive control in the in-vehicle main control screen, as shown in FIG. Figure 3 As shown, the car's main control screen will display the DLP projection controls.

[0061] S1012: Respond to the user's second click operation on the DLP projection control in the vehicle main control screen to determine whether the car is currently in a parked state.

[0062] In this embodiment, after the user clicks the DLP projection control displayed on the in-vehicle main control screen, the in-vehicle central control device determines whether the car is currently in a parked state.

[0063] In this embodiment, whether the car is currently in a parking state can be determined by judging whether the car is currently in the P gear. Specifically, when the car is in the P gear, the car is in a parking state.

[0064] S102: When the car is in a parked state, identify whether there is a projection-enabled facade perpendicular to the ground within a preset distance range in front of the car headlights.

[0065] In this embodiment, the preset distance range is, for example, 5-12 meters, which is not limited in this application. The projection screen facade is arranged perpendicular to the ground. For example, the projection screen facade can be a wall or a curtain. Generally, the irradiation direction of the car headlight is perpendicular to the projection screen facade.

[0066] S103: When a projection-enabled facade perpendicular to the ground is set within a preset distance in front of the vehicle headlights, the current working mode of the vehicle headlights is switched to the projection mode, so that the content currently displayed on the vehicle main control screen is projected onto the projection-enabled facade through the projection mode of the vehicle headlights.

[0067] In this embodiment, the car headlights are devices for lighting on both sides of the head of the car, and the working modes of the car headlights may include high beam mode, low beam mode, off mode, strong light mode, weak light mode, flash mode and projection mode. By switching the working mode of the car headlights to the projection mode, the projection mode of the car headlights is used to project the content currently displayed on the vehicle main control screen to the projection-capable facade.

[0068] In a possible implementation manner, after executing step S101, the following steps may also be performed:

[0069] S104: When the car is in motion, a prompt message is displayed on the in-vehicle main control screen to indicate that the screen projection function is unavailable.

[0070] In this embodiment, when the car is in motion, the screen projection function is not allowed to be used, which helps to ensure that the driver's attention is not distracted, thereby ensuring driving safety.

[0071] In a possible implementation manner, after executing step S103, the following steps may also be performed:

[0072] S105: When the content currently displayed on the in-vehicle main control screen is the target video, in response to the user's control operation on the video adjustment component on the in-vehicle main control screen, the target video displayed on the projectable facade is adjusted; wherein the video adjustment component includes any one or more of the following: previous episode component, next episode component, pause component, play component, double speed component, progress bar component.

[0073] In this embodiment, the user can adjust the target video displayed on the projectable facade on the in-vehicle main control screen.

[0074] In a possible implementation manner, after executing step S103, the following steps may also be performed:

[0075] S106: When it is recognized that the current state of the car switches from the parking state to the driving state, the car headlights are controlled to exit the screen projection mode and end the screen projection.

[0076] In this embodiment, as long as the car enters the driving state, the car headlights will be directly controlled to exit the screen projection mode and end the screen projection. The driving state includes forward, reverse, turning, etc.

[0077] In a possible implementation manner, after executing step S103, the following steps may also be performed:

[0078] S107: When it is detected that the current state of the power battery in the car is a preset battery state, the car headlights are controlled to exit the screen projection mode and end the screen projection; wherein the preset battery state includes any one of the following: the remaining battery power is less than the preset power power, and the power battery is in IG off mode.

[0079] In this embodiment, there is no fixed execution order among steps S105, S106, and S107, and these three steps are in a parallel relationship.

[0080] In a possible implementation, at least one secondary display screen is further provided in the automobile. Exemplarily, two secondary display screens may be provided at the rear headrests of the automobile, and specifically, a secondary display screen may be provided at the rear headrest of the main driver's seat, and the secondary display screen faces the seat behind the driver's seat. A secondary display screen may also be provided at the rear headrest of the passenger seat, and the secondary display screen faces the seat behind the passenger seat.

[0081] In this embodiment, the following steps S201-S202 may also be performed:

[0082] S201: In response to the user's third click operation on the multi-screen interactive control in the vehicle main control screen, the DLP projection control and the display screen projection controls corresponding to each auxiliary display screen are displayed in the vehicle main control screen.

[0083] In this embodiment, if Figure 4 As shown, after the user clicks on the multi-screen interactive control in the car's main control screen, the DLP projection control and the display projection controls corresponding to each secondary display screen will be displayed on the car's main control screen.

[0084] S202: In response to the user's selection operation on the in-vehicle main control screen for a target display screen projection control in the display screen projection control, the content currently displayed on the in-vehicle main control screen is projected and displayed on the secondary display screen corresponding to the target display screen projection control.

[0085] In this embodiment, the target display screen projection control is selected by the user from the display screen projection controls. For example, if the user wants to project the content displayed on the vehicle's main control screen to the secondary display screen behind the main driver's seat, the target display screen projection control is the secondary display screen behind the main driver's seat.

[0086] In this embodiment, the selection operation may specifically be a click operation. After the user clicks the target display screen projection control, the content currently displayed on the vehicle main control screen will be projected and displayed on the secondary display screen corresponding to the target display screen projection control.
