Description

Technical Field

[0001] The present invention relates to the technical field of vehicle control, and particularly to an auxiliary display method and system for a large central control screen of a vehicle. Background Art

[0002] The large central control screen of a vehicle is a component that users need to frequently use during driving. However, current vehicles are increasingly developing towards intelligence, and there are generally problems of information overload and complex interaction logic on the large central control screen. Since most central control displays are arranged between the driver's seat and the passenger seat, the driver needs to turn their head to operate the screen. Frequent operation of the screen by the driver to switch functions easily leads to distraction. In addition, the fixed interface layout cannot adapt to different driving scenarios, such as high-speed driving, reversing, and night driving. Key information such as navigation and vehicle speed may be blocked by secondary content such as entertainment information. Although some technologies use split-screen display for multitasking, they do not achieve dynamic adjustment of priorities and scene adaptation, and there are still safety hazards. Therefore, it is necessary to design an auxiliary display method for the large central control screen of a vehicle to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide an auxiliary display method and system for a large central control screen of a vehicle to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An auxiliary display method for a large central control screen of a vehicle, including the following steps: First, after ignition, collect the real-time state of the vehicle, read the biometric characteristics of the driver, and monitor the environment for data to determine the driving scenario;

[0005] Dynamically allocate screen areas according to the scene risk level and task priority;

[0006] Judge the priorities of voice, gesture, and touch screen according to the scene risk level;

[0007] When the driver is distracted while driving, increase the warning information and automatically remind.

[0008] Preferably, by collecting the vehicle speed, gear position, and turn signal of the vehicle in real time, adaptively adjust the display content of the central control screen. When the vehicle's forward speed exceeds 60 km / h, the central control screen enlarges and displays navigation information. When the vehicle gear is shifted to the reverse gear, the central control screen enlarges the reverse image and the 360 image, and the navigation information is reduced. When the turn signal is on, the central control screen enlarges the side image of the vehicle on the side of the turn signal, and the navigation information is reduced. Update in real time through the GPS position, and adopt a pre-reminder mode. Navigation information can be enlarged in advance and the navigation information can be announced by voice when approaching an intersection or an on-ramp or off-ramp.

[0009] Preferably, in a reverse scenario, when the ultrasonic radar detects an obstacle, the screen is automatically divided into three areas: the reverse image accounts for 30%, the 360 simulation image accounts for 40%, the radar distance simulation diagram accounts for 20%, and the navigation thumbnail accounts for 10%. When the obstacle distance < 0.5m, the navigation thumbnail is switched to an impact warning.

[0010] Preferably, when the vehicle speed exceeds 80 km / h and the driver's line of sight deviates from the screen for more than 2 seconds, the risk scenario is determined to be the highest level. At this time, all non-essential controls are turned off, only the navigation information is retained, the touch operation is disabled, the priority of voice command response is increased, and the driver's line of sight is reduced from separating from the road surface.

[0011] Preferably, when the vehicle does not turn on the turn signal and the vehicle deviates from the lane, and the driver does not correct it with the steering wheel, the screen vibrates, and all non-safe controls on the screen are automatically folded, and a voice broadcast reminds the driver and asks whether to activate the automatic driving.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Method Embodiment

[0021] The present invention provides an auxiliary display method for a large central control screen of an automobile, including the following steps: First, after ignition, collect the real-time state of the vehicle, read the biometric characteristics of the driver, and monitor the environment for data to determine the driving scenario;

[0022] Dynamically allocate screen areas according to the scene risk level and task priority;

[0023] Judge the priorities of voice, gesture, and touch screen according to the scene risk level;

[0024] When the driver is distracted while driving, increase the warning information and automatically remind.

[0025] Specifically, by collecting the vehicle speed, gear position, and turn signal of the vehicle in real time to adaptively adjust the display content of the central control screen. When the vehicle's forward speed exceeds 60 km / h, the central control screen enlarges and displays the navigation information. When the vehicle gear is shifted to the reverse gear, the central control screen enlarges the reverse image and the 360 image, and the navigation information is reduced. When the turn signal is on, the central control screen enlarges the side image of the vehicle on the side of the turn signal, and the navigation information is reduced. It is updated in real time through the GPS position, and a pre-reminder mode is adopted. The navigation information can be enlarged in advance when approaching an intersection or an on-ramp or off-ramp, and the navigation information is reported by voice.

[0026] In the reverse scenario, when the ultrasonic radar detects an obstacle, the screen automatically divides into three areas: the reverse image accounts for 30%, the 360 simulation image accounts for 40%, the radar distance simulation diagram accounts for 20%, and the navigation thumbnail accounts for 10%. When the obstacle distance < 0.5 m, the navigation thumbnail switches to an impact warning.

[0027] When the vehicle speed exceeds 80 km / h and the driver's line of sight deviates from the screen > 2 s, the risk scenario is determined to be the highest level. At this time, all non-essential controls are closed, only the navigation information is retained, and the touch operation is disabled, and the priority of voice command response is increased to reduce the driver's line of sight from separating from the road surface.

[0028] When the vehicle does not turn on the turn signal and the vehicle deviates from the lane and the driver does not correct it with the steering wheel, the screen vibrates, and all non-safe controls on the screen are automatically folded, and a voice broadcast reminds the driver and asks whether to start the automatic driving.

[0029] Among them, the line-of-sight direction of the driver can be detected through an in-vehicle camera. After the driver deviates from the road surface for 3 seconds, voice broadcast prompts can be given, and the driver can be asked whether to turn on the autopilot. The driving state of the driver can also be detected, and a warning can be issued in the case of fatigue.

[0030] In the priority instructions, according to the urgency of the navigation instructions, such as the need to enter / exit the ramp and the pre-broadcast of the turning distance, information is conveyed to the driver in advance, which is more convenient for the driver to make judgments. When lane departure occurs, a safety warning is issued to remind the driver to correct.

[0031] In high-risk scenarios, non-essential control software is turned off, such as music, video, and Bluetooth display interfaces. Only navigation road condition information is retained, and the touch screen is disabled. Gesture and voice interactions are used to control the display screen.

[0032] Environmental adaptive adjustment can be achieved through the camera. In the night state with insufficient light illumination, the screen brightness is reduced and the dark theme is switched. At the same time, in key information areas such as the road sign prompt module, high contrast is used for area division, and voice broadcast is performed to facilitate timely prompting to the driver.

[0033] An auxiliary display system for a car's central control large screen, by allocating the priority display content on the screen according to different scenarios. In specific scenarios, non-essential content is folded and hidden, improving the priority display of information in different scenarios, reducing the scenarios that distract the driver, and in high-risk scenarios on the highway, the screen raises the priority of voice interaction to avoid the danger of distracting the driver during high-speed driving.

[0034] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
