Attached Figure Description

[0031] The invention will now be described in more detail with reference to the accompanying drawings, which will provide a better understanding of its principles, features, and advantages. The drawings include:

[0032] Figure 1 A driving glasses control system according to an exemplary embodiment of the present invention is schematically illustrated;

[0033] Figure 2 A flowchart illustrating the main steps of a driving glasses control method according to an exemplary embodiment of the present invention is shown schematically; and

[0034] Figure 3 A vehicle having a driving glasses control system according to an exemplary embodiment of the present invention is illustrated schematically. Detailed Implementation

[0035] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of this invention.

[0036] Figure 1 A driving glasses control system 10 according to an exemplary embodiment of the present invention is illustrated schematically. The driving glasses control system 10 according to an exemplary embodiment of the present invention includes at least: driving glasses 1, the driving glasses 1 being configured such that the light transmittance of the lenses can be adjusted; and a control unit 2, the control unit 2 being configured to adjust the light transmittance of the lenses, wherein the control unit 2 is configured to allow adjustment of the light transmittance of the lenses based on vehicle location information. For example, when it is determined based on location information that the vehicle is in an outdoor environment and is about to enter a building facility such as a tunnel or indoor parking lot, or when the vehicle is in a dark environment such as a tunnel or indoor parking lot and is about to enter a bright outdoor environment, the control unit 2 adjusts the light transmittance of the lenses in advance to prepare for the upcoming change in light.

[0037] Therefore, such as Figure 1As shown, the driving glasses control system 10 according to an exemplary embodiment of the present invention may further include one or more of the following: a navigation module 3, which can be used to acquire vehicle location information and can further acquire navigation information of vehicle travel; a light intensity detection module 4, which is used to detect ambient light intensity and generate light intensity information; and a high-precision map information module 5, which is used to acquire in-vehicle high-precision map information. Thus, the control unit 2 can be configured to allow adjustment of the lens transmittance by combining light intensity information and / or navigation information and / or high-precision map information.

[0038] In one embodiment, the control unit 2 is configured to allow, before the vehicle enters a road segment where the change in light intensity compared to the current road segment is greater than a first threshold, the lens transmittance to be adjusted to a transmittance suitable for the road segment ahead, based on navigation information and / or high-precision map information predicting that the vehicle will enter such a road segment. Here, the first threshold is less than or equal to the maximum change in light intensity that does not affect the visual sensitivity of the human eye, or in other words, the first threshold is less than or equal to the maximum change in light intensity that does not cause the human eye to undergo light adaptation or dark adaptation.

[0039] For example, when it is determined, based on location information or a combination of navigation information and / or high-precision map information, that a vehicle will enter a dimly lit tunnel from an outdoor environment, and the predicted change in light intensity is greater than a first threshold, the lens transmittance is increased towards the light intensity suitable for the tunnel before the vehicle enters the road ahead and the light intensity decreases sharply. This allows the driver to adapt smoothly to the light intensity inside the tunnel without undergoing a dark adaptation process, avoiding momentary blindness and ensuring safe driving. Alternatively, when it is determined that the vehicle will exit a dimly lit tunnel and enter a bright outdoor environment, and the change in light intensity is greater than a first threshold, the lens transmittance is decreased towards the light intensity suitable for outdoor light, allowing the driver to adapt smoothly to the outdoor light intensity without undergoing a light adaptation process.

[0040] In one embodiment, the lenses of the driving glasses are configured to include an electrochromic layer that is configured to change light transmittance in response to a change in the current passing through the electrochromic layer by a control unit.

[0041] In one embodiment, the lenses of the driving glasses are configured to further include an information display layer disposed inside the electrochromic layer for displaying driving information and / or images, thereby enabling the driver to obtain basic driving information without having to look at the dashboard when wearing the driving glasses, providing convenience for the driver and further ensuring driving safety.

[0042] In one embodiment, the driving glasses control system further includes a glasses case for housing the driving glasses and positioned on the vehicle dashboard. The glasses are switched to a closed state when placed in the glasses case and switched to an operational state when worn. The glasses case may also be configured to charge the driving glasses when placed in it, and the glasses case may also be manually opened and closed. The glasses case may be configured to be flush with the dashboard surface when closed, and to raise the driving glasses to a height protruding from the dashboard surface when opened for easy access by the driver. The glasses case may also be equipped with a prompting module to generate a prompt signal, for example, in the form of sound or light, when the glasses case is opened, prompting the driver to put on or put away the glasses.

[0043] In one embodiment, the control unit is also configured to allow the opening and closing of the glasses case to be controlled by incorporating light intensity information, the status of the driving glasses, and predetermined reference factors.

[0044] The predetermined reference factors can include day and night time periods. In this configuration, the control unit can open the sunglasses holder and eject the sunglasses during daytime when the light intensity is greater than a second threshold and the driving glasses are closed, and retract and close the sunglasses holder after the driving glasses are switched to operating mode. Alternatively, during non-daytime periods, such as dusk, when the light intensity is less than the second threshold and the driving glasses are in operating mode, the control unit can open the sunglasses holder and retract and close it after the driving glasses are switched to closed mode. Here, the second threshold is the light intensity at which the driver needs to wear sunglasses, which can be set by the driver according to their own needs. This ensures that driving glasses are provided to the driver in a timely and appropriate manner, or that the driver is reminded to remove their driving glasses, without frequently and unnecessarily opening and closing them due to changes in light intensity, thus affecting the driving experience.

[0045] Other factors may also be included in the pre-booking reference, without any particular restrictions.

[0046] Figure 2 A flowchart illustrating the main steps of a driving glasses control method according to an exemplary embodiment of the present invention is shown schematically. Figure 2 As shown, a driving glasses control method according to an exemplary embodiment of the present invention mainly includes the following steps:

[0047] S1: Obtain vehicle location information; and

[0048] S2: Adjust the light transmittance of the driving glasses lenses based on the vehicle's location information.

[0049] According to one embodiment, the driving glasses control method may further include: acquiring vehicle navigation information and / or high-precision map information; acquiring light intensity information; and, when it is predicted, based on the navigation information and / or high-precision map information, that the vehicle will enter a road segment ahead where the change in light intensity compared to the current road segment is greater than a first threshold, adjusting the light transmittance of the lenses towards a transmittance suitable for the road segment ahead before the vehicle enters the road segment ahead. The light transmittance of the lenses can be adjusted linearly within a predetermined time before entering the road segment ahead, allowing the human eye to gradually adapt to the change in light without experiencing momentary blindness.

[0050] In one embodiment, the driving glasses control method may further include displaying vehicle driving information and / or images, such as vehicle speed, navigation arrows, etc., using the driving glasses. Furthermore, the display brightness of the vehicle driving information can be adjusted based on light intensity information and lens transmittance to make the driving information clearer and less glaring.

[0051] Figure 3 A vehicle having a driving glasses control system according to an exemplary embodiment of the present invention is illustrated schematically. Figure 3 As shown, the vehicle includes a driving glasses control system 10 and a controller 100 according to the present invention.

[0052] The controller 100 is implemented, for example, as an electronic control unit (ECU) of a vehicle. The controller may include a memory and a processor. The memory stores computer program instructions, which, when executed by the processor, enable the processor to perform, or at least assist in performing, the methods described above according to embodiments of the present invention. The computer program product may be stored in a computer-readable storage medium. The computer-readable storage medium may include, for example, high-speed random access memory, and may also include non-volatile memory such as a hard disk, RAM, plug-in hard disk, smart memory card, secure digital card, flash memory card, at least one disk storage device, flash memory device, or other volatile solid-state storage device. The processor may be a central processing unit, or other general-purpose processors, digital signal processors, application-specific integrated circuits, off-the-shelf programmable gate arrays or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor may be a microprocessor or any conventional processor, etc. The controller 10 may be a dedicated controller for the driving glasses control method according to embodiments of the present invention, or it may be integrated into the vehicle's central controller, or the controller 100 may be implemented as the central controller.
