[0019] At present, the interior lighting system of automobiles, especially commercial vehicles, has long been mainly using fixed lamps such as ceiling lights, step lights, and reading lights to solve the problem of interior lighting. In recent years, some models have introduced various color atmosphere lights and other lamps to improve night driving lighting and light atmosphere. The number of interior lamps in the cab is increasing, but it still has the disadvantages of constant brightness and single direction of fixed emitting light sources, and has not solved the various lighting needs of users from the source.

[0020] Therefore, if Figure 1 As shown, the embodiment of the present application provides a method for controlling a lighting system in a cab, including:

[0021] S1 obtains the user's lighting control needs;

[0022] When the user has lighting control requirements, S2 can obtain the user image in the cab in real time;

[0023] S3 controls the operation of the lighting system according to the user image in the cab.

[0024] Improving the lighting usage of users in different positions in the cab can make the vehicle cab lighting system more adaptable. By acquiring the user image in the cab, the lamps can be lit according to the user's needs to achieve a high-efficiency lighting effect.

[0025] As an optional implementation, obtaining the user's lighting control needs includes: automatically determining the user's lighting control needs based on the vehicle operating conditions, the external environment and the user image in the cab; or obtaining an output signal output by the user for indicating the start of lighting control.

[0026] That is, the user's lighting control demand may be that the user actively outputs a command for lighting control, for example, a button is set in the cab, when the user in the cab presses the button, it indicates that the user needs lighting and needs to control the lighting at this time, and pressing the button again indicates that the user no longer needs lighting control; it may also be that the vehicle main control system automatically determines the user's lighting control demand according to the vehicle working condition, the environment outside the vehicle, and the user image in the cab, for example, when the vehicle is at night or in a low-light environment, after the vehicle is turned off, it means that the user needs to get off the vehicle or perform some other operations, and the lighting control can be automatically turned on at this time. It can also be set to control the operation of the lighting system when the user's lighting control demand is automatically determined according to the vehicle working condition, the environment outside the vehicle, and the user image in the cab, and control the operation of the lighting system according to the user image in the cab when the output signal actively output by the user for indicating the start of lighting control is obtained, and this application does not limit this.

[0027] As an optional implementation, controlling the operation of the lighting system based on the user image in the cab includes: determining the user's facial orientation information, user posture information and body coordinate information in real time based on the user image in the cab; converting the user's facial orientation information, user posture information and body coordinate information to obtain a data signal for characterizing the user's real-time dynamic position; and determining the overall illumination angle and illumination intensity of the lighting system based on the data signal for characterizing the user's real-time dynamic position.

[0028] Specifically, the image processing module obtains the user's facial orientation and body position information and converts it into information such as the user's visual direction and coordinates. The lighting control module analyzes the lighting drive and light distribution logic based on the user's posture information obtained by the image processing module. When the user triggers the need to use the light, the image processing module outputs a driving signal to the controllable lamps, and lights up the controllable lamps in response to the driving signal to achieve a high-efficiency lighting effect.

[0029] As an optional embodiment, the lighting system in the cab includes a plurality of controllable lamps distributed at different positions, having different luminous intensities and different illumination angles; determining the overall illumination angle and illumination intensity of the lighting system according to the data signal for characterizing the real-time dynamic position of the user includes: controlling the turning on and off of the plurality of controllable lamps respectively according to the data signal for characterizing the real-time dynamic position of the user and the status information of the controllable lamps.

[0030] The lighting system includes one or more lamps with fixed or variable light intensity or illumination angle arranged at different positions in the cab. They can also form different lamp combinations. The lamp combinations can be one, two or more. When the user's lighting control needs are obtained, the controllable lamps or lamp combinations at different positions will open and close, adjust the brightness and illumination direction according to the received instructions to meet the user's needs for regional lighting.

[0031] As an optional implementation, controlling the turning on and off of the plurality of controllable lamps according to the data signal characterizing the real-time dynamic position of the user and the status information of the controllable lamps includes: verifying the turning on and off of the plurality of controllable lamps according to a light distribution algorithm.

[0032] As an optional implementation, the light distribution algorithm includes: Where L a (t) is the ambient brightness, L p (t) is the luminous intensity of the controllable lamp with fixed direction and fixed brightness, n is the number of controllable lamps with adjustable brightness and direction, Ki is the luminous effect coefficient of the controllable lamp with adjustable brightness and direction, L i[s t(x，y，z) ,q t is the luminous intensity of a controllable lamp with adjustable brightness and direction, s t(x，y，z) and q t It is a parameter of the real-time dynamic location of the user.

[0034] The image processing module can collect user video information through the vehicle-mounted camera. The image processing module parses the video signal into orientation information, and the orientation and other information are transferred to the lighting control module. The lighting control module parses the acquired orientation information into a lighting control signal through a control strategy. When the user has a lighting control demand, the lighting control module outputs the control signal to the controllable lamps or lamp combinations in the cab, and each lamp adjusts the brightness and angle according to the control signal.
