Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

It should be noted that the embodiments of the present invention and the technical features in the embodiments may be combined with each other without collision.

In addition, the terms "first," "second," "third," etc. in the terms of embodiments of the present invention are used to distinguish similar objects from each other, and are not necessarily used to describe a specific number or order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and are merely illustrative of the manner in which embodiments of the invention have been described in connection with objects of the same nature.

The vehicle according to the embodiment of the invention may be an internal combustion engine vehicle having an engine as a power source, a hybrid vehicle having an engine and an electric motor as power sources, an electric vehicle having an electric motor as a power source, or the like.

Fig. 1 shows a main flow diagram of a vehicle end projection method according to an embodiment of the present invention. As shown in fig. 1, the vehicle end projection method provided by the embodiment of the invention may include the following steps:

step S101: determining a simulation scene in response to the projection trigger, and generating a pattern to be projected corresponding to the simulation scene according to the simulation scene;

the simulation scene refers to information indicating characteristics, types and the like of games or activities required by a user, which are obtained by a controller at a vehicle end, such as an ECU (electronic control Unit) based on characteristic identification information or indication signals and the like, for example, an identification defined for basketball sports is B, an identification defined for badminton sports is C, the ECU determines that the simulation scene is basketball sports when acquiring the identification B provided by projection triggering, and the ECU determines that the simulation scene is badminton sports when acquiring the identification C provided by projection triggering. In addition, the simulated scene may also be other sports or games such as sprint, football, chess, checkers, house-jump games, and the like.

The pattern to be projected may be a complete pattern corresponding to a playing field or a game field or a partial pattern corresponding to a playing field or a game field.

Step S102: determining a projection area according to the position information of the vehicle;

the projection area is generally the area occupied by the pattern to be projected onto a floor or wall surface or the like.

Step S103: and controlling the emergent light beam of the car lamp of the car according to the projection area and the pattern to be projected so as to project a simulation field containing the pattern to be projected on the projection area, so that a user plays or moves on the simulation field projected by the car lamp.

The outgoing beam of the vehicle lamp of the control vehicle can be realized by adopting the existing vehicle lamp control mode, and the description is omitted here.

Aiming at the technical scheme provided by the embodiment shown in fig. 1, a simulation scene is determined, a pattern to be projected is generated according to the simulation scene, then a projection area is determined according to the position information of a vehicle, and then a simulation site containing the pattern to be projected is projected on the projection area by controlling the vehicle lamp of the vehicle, so that a user plays or moves on the simulation site projected by the vehicle lamp, namely, the scheme provided by the embodiment of the invention can control the vehicle lamp to project the site and scene required by the game or the movement for the user, and thus richer entertainment experience is provided for the user through the vehicle.

In response to the projection trigger in step S101, two specific embodiments of determining the simulated scene may be used.

A first embodiment of determining a simulated scene may include: providing a plurality of selectable simulation scenes to a user through a display device; and in response to the user selecting any one of the target selectable simulation scenes, determining the target selectable simulation scene as the simulation scene. The ECU provides selectable simulation scenes for a user through the vehicle-mounted display, and after the display screen receives the trigger of the user for any simulation scene displayed, the ECU provides the characteristic identifiers corresponding to the triggered simulation scenes, so that the ECU determines the simulation scene selected by the user.

A second embodiment of determining a simulated scene may include: receiving a field image input by a user; from the field images, a simulated scene is generated. For example, when a user inputs an image of a sports field or an image of a game field through a terminal device, an in-vehicle display device, or the like, the ECU recognizes feature information of the field or the like from the image, and combines the recognized feature information into a simulation scene.

According to the embodiment of the invention, through the two modes for determining the simulation scene, a user can flexibly select any mode according to the requirement to obtain the required simulation field. Further, the second specific implementation mode of determining the simulation scene can realize expansion of the simulation scene so as to better meet the outdoor entertainment or sports requirements of users.

Further, the technical scheme provided by the embodiment of the invention can provide different projection modes such as a single-vehicle projection mode and a multi-vehicle projection mode for users so as to meet different requirements of the users. Specifically, for the above generation of the pattern to be projected corresponding to the simulated scene, there are different implementations for different projection scenes or projection modes.

Wherein, for the single vehicle projection mode selected by the user, the specific implementation of generating the pattern to be projected corresponding to the simulated scene can comprise: determining the size of the simulated scene; a complete pattern is generated that matches the size of the simulated scene. For example, for a sprint scene, where the user selects the single vehicle projection mode (i.e., projects a sprint by one vehicle), a sprint having three sprints is projected by vehicle Ve1 as shown in fig. 2. The size of the simulated scene generally refers to the size of the simulated field to be projected, such as length, width, etc.

Further, for a multi-vehicle projection mode selected by a user (i.e. a pattern projected by a plurality of vehicles is combined into a complete field), the specific embodiment of generating a pattern to be projected corresponding to a simulated scene may include: for each vehicle related to the multi-vehicle projection mode, determining a part of simulation scenes corresponding to the vehicles according to the position information of the vehicles, and generating patterns to be projected corresponding to the part of simulation scenes so as to enable the patterns to be projected of the part of simulation scenes corresponding to the plurality of vehicles to be combined into a complete simulation scene. The positional information of the vehicle generally refers to relative positional information between a plurality of vehicles, for example, a badminton court shown in fig. 3A, a soccer court shown in fig. 4, or the like can be projected by the multi-vehicle projection mode. For example, the badminton court shown in fig. 3A is projected by vehicles Ve1, ve2, ve3 and Ve4 together, where the vehicle Ve1 generates a pattern P1 to be projected corresponding to a partially simulated scene as shown in fig. 3B, the vehicle Ve2 generates a pattern P2 to be projected corresponding to a partially simulated scene as shown in fig. 3C, the vehicle Ve3 generates a pattern P3 to be projected corresponding to a partially simulated scene as shown in fig. 3D, and the vehicle Ve4 generates a pattern P4 to be projected corresponding to a partially simulated scene as shown in fig. 3E, and then the P1 shown in fig. 3B, the P2 shown in fig. 3C, the P3 shown in fig. 3D and the P4 shown in fig. 3E projected on the ground splice the badminton court shown in fig. 3A. For another example, the soccer field shown in fig. 4 is projected by vehicles Ve1, ve2, ve3, ve4, ve5 and Ve6, where vehicle Ve1 generates a pattern corresponding to an area corresponding to a P10 of the pattern to be projected of the partial simulation scene as shown in fig. 4, vehicle Ve2 generates a pattern corresponding to an area corresponding to a P8 of the pattern to be projected of the partial simulation scene as shown in fig. 4, vehicle Ve3 generates a pattern corresponding to an area corresponding to a P7 of the pattern to be projected of the partial simulation scene as shown in fig. 4, vehicle Ve4 generates a pattern corresponding to an area corresponding to a P5 of the pattern to be projected of the partial simulation scene as shown in fig. 4, vehicle Ve5 generates a pattern corresponding to an area corresponding to a P9 of the pattern to be projected of the partial simulation scene as shown in fig. 4, and then the patterns corresponding to P5 to P10 can be obtained directly on the ground as shown in fig. 4. A complete activity or sports ground is spliced through the patterns projected by multiple vehicles, so that the requirements of users on a larger sports ground in suburbs can be met, and better game or sports entertainment experience is provided for the users.

It should be noted that, fig. 3B to fig. 3E and fig. 4 are only exemplary to show possible projection patterns of each vehicle, the patterns projected by each vehicle or the sizes of the patterns, etc. may be regulated according to requirements, for example, the lines of the patterns projected by adjacent vehicles may be partially overlapped, the lengths of the lines projected by the vehicles may be increased or decreased, etc. Any scheme as long as the patterns projected by multiple vehicles can be combined into one finished sports field is within the protection scope of the application.

Further, as shown in fig. 5, for the multi-vehicle projection mode, one embodiment of determining the projection area may include the following steps:

step S501: determining the range of the area surrounded by the vehicles according to the position information of the vehicles, and determining the central point of the range of the area;

as described above, the positional information of the plurality of vehicles refers to relative positional information between the plurality of vehicles, for example, a coordinate system is drawn with one vehicle as a coordinate origin, and coordinates of other vehicles in the coordinate system are plotted. For example, in the case of fig. 3A where four vehicles are required to project a badminton court, the positions of Ve2, ve3, and Ve4 relative to Ve1 are adaptively adjusted according to the size of the badminton court and the position of Ve1 where the vehicles are located as the origin of coordinates. The positions of Ve1, ve2, ve3 and Ve4 can be determined by the position of the vehicle lamp or the vehicle head.

Step S502: dividing an area block matched with each vehicle according to the central point and the area range;

for example, for the scenario shown in fig. 3A, the area encompassed by four vehicles may be equally divided into four area blocks.

Step S503: judging whether the area block is within the light beam coverage range of the vehicle lamp, if yes, executing step S504; otherwise, N, execute step S505;

the judgment of whether the area block is within the light beam coverage range of the vehicle lamps is to judge that the patterns formed by each vehicle can not be spliced, if the light beam of any vehicle lamp can not cover the corresponding area block, the projected sports ground is defective, and the user experience is affected.

Step S504: determining the area block as a projection area, and ending the current flow;

step S505: the user is reminded to adjust the projection range of the vehicle.

The adjusting the projection range of the vehicles can be to increase the projection range of the adjacent vehicles under the condition that the projection range of one vehicle is smaller than the matched area block of the vehicles so as to ensure that the complete pattern of the sports ground is spliced.

Further, for the multi-vehicle projection mode, the specific implementation of projecting the simulated field including the pattern to be projected on the projection area may include: and splicing the to-be-projected patterns generated by a plurality of vehicles into a complete simulation field. I.e. the patterns projected as in fig. 3B to 3E are spliced on the ground to form a badminton court as shown in fig. 3A.

Further, for the above multi-vehicle projection mode, any one or more vehicles perform the following operations:

detecting the superposition condition between the pattern to be projected by the adjacent vehicle on the corresponding projection area and the pattern to be projected by the own vehicle on the corresponding projection area; the detection process can be carried out through the vehicle-mounted camera, the sizes of patterns projected by all vehicles can be obtained through mutual communication among multiple vehicles, and the overlapping condition among the patterns is judged according to the sizes of the patterns and the position information of the vehicles. For example, with respect to fig. 3B to 3E, the overlapping of the projected pattern P1 shown in fig. 3B and the projected pattern P2 of fig. 3C, the overlapping of the pattern P2 shown in fig. 3C and the projected pattern P3 of fig. 3D, and the overlapping of the pattern P4 shown in fig. 3D and the projected pattern P4 of fig. 3E are detected, respectively.

And if the superposition condition indicates that deviation exists between the pattern to be projected by the own vehicle and the pattern to be projected by the adjacent vehicle, adjusting the pattern to be projected by the own vehicle or indicating the adjacent vehicle to adjust the projected pattern to be projected. The deviation can give out the deviation of how large the projected adjacent patterns exist, so that the ECU of the vehicle can adjust the light beam of the vehicle lamp according to the deviation, thereby achieving the purpose of adjusting parameters such as the direction, the size and the like of the patterns. Through the process, the projection of multiple vehicles on a complete sports ground or a sports ground can be ensured, so that the user experience is improved.

Taking the scene shown in fig. 4 as an example, the implementation process of the vehicle end projection will be described in detail. As shown in fig. 6, the vehicle end projection may include the following steps:

step S601: controlling each vehicle from Ve1 to Ve6 to enter a multi-vehicle projection mode, wherein any vehicle from Ve1 to Ve6 provides a plurality of selectable simulation scenes for a user through a display device;

step S602: determining a size of the simulated scene in response to the user selecting the football scene;

step S603: according to the size of the simulated scene and the position of any vehicle, enabling a user to adjust the positions of other vehicles;

step S604: determining the range of the area surrounded by the vehicles according to the position information of the vehicles, and determining the central point of the range of the area;

step S605: dividing an area block matched with each vehicle according to the central point and the area range;

each of the vehicles Ve1 to Ve6 performs steps S604 to S described below. . . . :

step S606: determining a part of simulation scene corresponding to the vehicle according to the position information of the vehicle, and generating a pattern to be projected corresponding to the part of simulation scene;

for example, for the football field of fig. 4, through this step, the vehicle Ve1 may determine the simulated scene and the pattern to be projected corresponding to P10, the vehicle Ve2 may determine the simulated scene and the pattern to be projected corresponding to P8, the vehicle Ve3 may determine the simulated scene and the pattern to be projected corresponding to P7, the vehicle Ve4 may determine the simulated scene and the pattern to be projected corresponding to P5, the vehicle Ve5 may determine the simulated scene and the pattern to be projected corresponding to P9, and the vehicle Ve6 may determine the simulated scene and the pattern to be projected corresponding to P6.

It should be noted that, there is no strict sequence between the step S605 and the step S606.

Step S607: judging whether the area block is within the light beam coverage range of the vehicle lamp, if so, executing step S608; otherwise, step S609 is performed;

step S608: determining the region block as a projection region, and executing step S610;

step S609: reminding a user to adjust the projection range of the vehicle;

step S610: and controlling the emergent light beam of the car lamp of the car according to the projection area and the pattern to be projected so as to project a simulation field containing the pattern to be projected on the projection area, so that a user plays or moves on the simulation field projected by the car lamp.

The football field as shown in fig. 4 is projected on the ground by the vehicles Ve1 to Ve6 shown in fig. 4 according to the determined projection area and the relevant parameters of the pattern to be projected, such as the size, width, etc. of each line of the pattern.
