TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent cockpit, and in particular to a vehicle-mounted cockpit screen inclination control system and method. BACKGROUND

[0002] At present, the position of the large screen in the cockpit of the automobile market is mostly in the middle of the car. The main driver or the copilot needs to lean the body or even operate in a crouched position for a long time when operating the large screen, which has different degrees of influence on the spine and cervical vertebrae, and increases the user's bad experience. And now the intelligent cockpit cancels most of the physical buttons. When operating the soft switch of the large screen, it needs to slide to find the corresponding function switch. This may cause safety problems when the main driver wants to adjust the soft switch during driving, and the large screen may reflect light and the driver may adjust the body posture.

[0003] Chinese Patent Publication No. CN116636808A discloses an intelligent cockpit driver visual health degree analysis method and device. The method includes: building a real-time iris posture model of the driver in the intelligent cockpit; based on the real-time iris posture model and the real-time light data received by the driver's eyeball and the screen activity data in the intelligent cockpit, a visual active light interference model of the driver's eyeball is built; the visual active light interference model is analyzed to obtain the driver's visual adjustment force; and the driver's visual health degree analysis result is obtained based on the driver's visual adjustment force. The light interference and the driver's visual active state in the intelligent cockpit are analyzed. However, this scheme only analyzes and adjusts the visual health degree of the cockpit driver, and cannot solve the problem of low driving safety caused by the reflection of the large screen and the adjustment of the driver's body posture. SUMMARY

[0004] Therefore, the present application provides a vehicle-mounted cockpit screen inclination control system and method to overcome the problem of low safety caused by the reflection of the large screen and the adjustment of the driver's body posture due to the low control efficiency of the vehicle-mounted cockpit screen in the prior art.

[0005] To achieve the above-mentioned purpose, in one aspect, the present application provides a vehicle-mounted cockpit screen inclination control system, comprising:

[0006] An OMS system is used to collect and process the face of the driver. The OMS system is provided with a camera and a control module. The camera is used to collect the face of the cockpit personnel to obtain a face image. The control module is used to process the face image to obtain a processed face image.

[0007] A seat control module is used to collect the seat information of the cockpit personnel.

[0008] The audio host is used for processing the processed face image and the driver's seating information to obtain a cabin screen inclination control signal, and is connected with the OMS system and the seat control module.

[0009] The cabin screen control module is used for controlling the cabin screen according to the cabin screen inclination control signal, and is connected with the audio host.

[0010] Further, when processing the face image, the control module inputs the face image into an effective frame model, obtains an identification result output by the effective frame model, and judges the collection effectiveness of the face image according to the identification result, wherein:

[0011] When the identification result output by the effective frame model is an effective frame, the control module determines that the face image collection is effective, and marks the face image as an effective frame.

[0012] When the identification result output by the effective frame model is an invalid frame, the control module determines that the face image collection is invalid.

[0013] Further, when processing the face image, the control module performs data comparison between the face image marked as an effective frame and an image database, and outputs the height and the line of sight of a preset face image consistent with the face image of the effective frame in the image database as the height of the cabin personnel and the line of sight of the cabin personnel.

[0014] Further, the seat control module collects the cabin personnel seating information through pressure sensors arranged at the main driver position and the co-driver position.

[0015] Further, the audio host judges the left and right control signals of the cabin screen inclination control signal according to the line of sight of the cabin personnel and the cabin personnel seating information, wherein:

[0016] When the cabin personnel seating information is that there is a person at the main driver position and there is a person at the co-driver position, the audio host judges the left and right control signals of the cabin screen inclination control signal according to the line of sight of the cabin personnel at the main driver position, wherein:

[0017] If the line of sight of the cabin personnel at the main driver position is the line of sight of the cabin personnel paying attention, the audio host determines that the left and right control signals of the cabin screen inclination control signal are the main driver inclination signal.

[0018] If the line of sight of the cabin personnel at the main driver position is the line of sight of the cabin personnel not paying attention, the audio host determines that the left and right control signals of the cabin screen inclination control signal are the co-driver inclination signal.

[0019] When the cabin occupant information is that the main driver position has an occupant and the co-driver position has no occupant, the audio host determines that the left and right control signals of the cabin screen inclination control signal are the co-driver inclination signals;

[0020] When the cabin occupant information is that the main driver position has no occupant and the co-driver position has an occupant, the audio host determines that the left and right control signals of the cabin screen inclination control signal are the co-driver inclination signals;

[0021] When the cabin occupant information is that the main driver position has no occupant and the co-driver position has no occupant, the audio host determines that the left and right control signals of the cabin screen inclination control signal are no signals.

[0022] Further, the audio host compares the height of the cabin occupant with the preset height in the signal database, and judges the height control signal of the cabin screen inclination control signal according to the comparison result, wherein:

[0023] When there is a preset height consistent with the height of the cabin occupant in the signal database, the audio host takes the preset height control signal corresponding to the preset height consistent with the height of the cabin occupant in the signal database as the height control signal of the cabin screen inclination control signal;

[0024] When there is no preset height consistent with the height of the cabin occupant in the signal database, the audio host sets the preset height control signal corresponding to the preset height with the smallest height difference from the height of the cabin occupant as the height control signal of the cabin screen inclination control signal;

[0025] The audio host sends the cabin screen inclination control signal to the cabin screen control module.

[0026] Further, the cabin screen control module controls the left and right of the cabin screen according to the left and right control signals of the cabin screen inclination control signal, and controls the height of the cabin screen according to the height control signal of the cabin screen inclination control signal.

[0027] Further, the cabin screen control module obtains the number of times of active adjustment of the co-driver position cabin occupant in the control feedback period, compares the number of times of active adjustment of the co-driver position cabin occupant P with the preset number of times of active adjustment of the personnel P0, and judges the cabin occupant riding priority according to the comparison result, wherein:

[0028] When P≤P0, the cabin screen control module determines that the cabin occupant riding priority is the main driver position cabin occupant priority;

[0029] When P>P0, the cabin screen control module determines that the cabin occupant riding priority is the co-driver position cabin occupant priority.

[0030] Further, the cabin screen control module adjusts the judgment process of the left and right control signals of the cabin screen inclination control signal according to the cabin personnel riding priority, wherein:

[0031] When the cabin personnel riding priority is the priority of the main driver position cabin personnel, the cabin screen control module determines not to adjust the judgment process of the left and right control signals of the cabin screen inclination control signal;

[0032] When the cabin personnel riding priority is the priority of the co-driver position cabin personnel, the cabin screen control module determines to adjust the result of the judgment process of the left and right control signals of the cabin screen inclination control signal, wherein the main driver position has personnel and the co-driver position has personnel, and wherein:

[0033] If the cabin personnel line of sight of the co-driver position is the cabin personnel attention line of sight, the cabin screen control module adjusts the left and right control signals of the cabin screen inclination control signal to the co-driver inclination signal;

[0034] If the cabin personnel line of sight of the co-driver position is the cabin personnel non-attention line of sight, the cabin screen control module adjusts the left and right control signals of the cabin screen inclination control signal to the main driver inclination signal.
