DETAILED DESCRIPTION

[0041] In order to make the above-mentioned purposes, features and advantages of the present disclosure more obvious and easy to understand, the present disclosure will be described in detail below with reference to the drawings and specific embodiments.

[0042] In the related art of image display on the sun visor, an image display module is mainly arranged on the sun visor of the vehicle, and some vehicle information is displayed by using the display module. The image display module can be a non-transparent area as shown in FIG. 1, and the transparent area other than the non-transparent area can ensure the driver to observe the road conditions in front. Although the foregoing scheme shortens the distance between the eyes of the driver and the displayed image by using the head-up display technology, avoids the image distortion problem caused by the long distance, and improves the reliability of imaging. However, the shortening of the distance will increase the visual fatigue of the passengers in the vehicle, and cannot present the required display of the vehicle information with better visual effect.

[0043] Therefore, some embodiments of the present disclosure provide a sun visor assembly of a vehicle, which displays a first image containing driving information by a projection module arranged on the sun visor body, so as to display the first image containing driving information by the projection module integrated on the sun visor. In this way, the position advantage of the sun visor in front of the passenger seat can be utilized, the natural line of sight of the human eye can be fully utilized, the additional visual transfer can be avoided, and the cognitive load can be reduced. In the case of ensuring that the image information does not interfere with the normal line of sight of the passengers, the intuitive display of the image by the projection module on the sun visor body can directly inform the passengers, the passengers can understand, the problem of increasing the visual fatigue of the passengers due to the shortening of the distance can be avoided, and the driving experience is more comfortable and safe.

[0044] Moreover, the sun visor assembly of some embodiments of the present disclosure can be a sun visor assembly arranged in front of the passenger seat. The passengers can obtain the driving information in time through the projection assembly on the sun visor. On the one hand, the passengers can understand the driving information in time, and on the other hand, the passengers can remind the driver in time according to the driving information. For example, when the driver does not pay attention to some information or when an emergency occurs, the passengers can remind in time according to the driving information, and the driving safety of the vehicle is ensured.

[0045] In addition, the projection module is a light waveguide projection module. By using the light waveguide imaging technology, virtual imaging in front of the vehicle can solve the problem of limited display space in the vehicle, increase the display area, so as to display more information, and also solve the problem of visual fatigue of the passengers, ensure the image display effect, and provide better visual experience for the passengers.

[0046] Referring to FIG. 2, a block diagram of a sun visor assembly of a vehicle according to some embodiments is shown. The sun visor assembly 2 can include a sun visor body 20 and a projection module 21 arranged on the sun visor body 20.

[0047] The projection module 21 can be configured to display a first image containing driving information. For example, the projection module 21 can be a light waveguide projection module 211, i.e., the light waveguide projection module 211 can be configured to display the aforementioned first image.

[0048] In some embodiments, the light waveguide projection module 211 can be a holographic light waveguide projection module or a diffractive light waveguide projection module. The holographic light waveguide and the diffractive light waveguide have the advantages of high adjustability, high integration, low loss and low crosstalk, etc. The interference pattern of light can be modulated and manipulated through the light waveguide to flexibly control the propagation path and characteristics of light, and complex optical functions can be realized in a small space.

[0049] As shown in FIG. 3, the light waveguide projection module 211 can include an image generation unit 2111 and a projection display unit 2112. The image generation unit 2111 can be configured to generate an optical image signal according to the driving information, and the projection display unit 2112 can be configured to display the first image according to the optical image signal.

[0050] In some embodiments, the projection display unit 2112 can be a light waveguide 21121. For example, the light waveguide 21121 can use light waveguide imaging technology for image display, and the imaging of the light waveguide 21121 depends on the image generation unit 2111 in the light waveguide projection module 211.

[0051] The image generation unit 2111 can include an electrical signal input module 21111, an optical modulation module 21112 and a light output module 21113. The electrical signal input module 21111 is mainly configured to receive an electrical signal containing driving information. The optical modulation module 21112 is mainly configured to convert the electrical signal into an optical signal. For example, the optical modulation module 21112 can change the characteristics of light by controlling the intensity or phase of the electrical signal, thereby converting the electrical signal into an optical signal. The light output module 21113 is mainly configured to convert the optical signal into an optical image signal corresponding to the first image. For example, the light output module 21113 processes the optical signal to convert the optical signal into a visible optical image signal, so as to finally present the aforementioned optical image through the light waveguide 21121 to provide the passenger with a view to facilitate the passenger to understand the relevant driving information.

[0052] In some embodiments, the optical waveguide projection module 211 can further include an image signal input unit 2113. The image signal input unit 2113 can be mainly responsible for transmitting the image signal containing driving information to the image generation unit 2111. In some embodiments, the transmission mode between the image signal input unit 2113 and the image generation unit 2111 can be selected according to the actual situation of the vehicle layout, electronic component selection, etc., and the transmission can be performed by wired connection, wireless connection or network. The wired connection can include but is not limited to High-Definition Multimedia Interface (HDMI), Video Graphics Array (VGA), Digital Visual Interface (DVI). The wireless connection can include but is not limited to Wireless Fidelity (Wi-Fi), Bluetooth. The network can include but is not limited to a local area network, the Internet, and the present disclosure does not limit this.

[0053] In some embodiments, the optical waveguide projection module 211 can further include a control board 2114, which can be mainly responsible for controlling the image generation unit 2111 to generate the first image containing driving information, so as to project the image generated by the image generation unit 2111 in the optical waveguide 21121 for display.

[0054] Referring to FIG. 4, an exploded view of the sun visor assembly according to some embodiments is shown. The sun visor body 20 can include a sun visor outer cover plate 201 and a sun visor inner cover plate 202, and the sun visor body 20 can be a structure of a conventional sun visor configured to shade. The projection module 21 provided on the sun visor body 20 can include an image generation unit 2111, a projection display unit 2112, and a control board 2114, and the projection display unit 2112 can be an optical waveguide 21121.

[0055] In some embodiments, the sun visor assembly 2 can further include a waveguide support 22 configured to fixedly install the optical waveguide 21121 and other optical components on the sun visor body 20.

[0056] It can be understood that in the application scenario of image display through the sun visor, the light waveguide imaging technology can be adopted by the projection module 21 to virtually image in front of the vehicle. As shown in FIG. 5, assuming that the projection module 21 is located in front of the passenger seat 5, for example, the projection module 21 is located in the direct front of the line of sight of the passenger sitting in the passenger seat 5, the first image displayed by the projection module 21 can be virtually imaged outside the preset distance in front of the vehicle, for example, at a. In this way, the position advantage of the sun visor located in front of the passenger seat can be fully utilized, the virtual image generated by the light waveguide imaging technology has stronger reality, the problem of limited display space in the vehicle can be solved, the display area is increased, so that more information can be displayed, the problem of visual fatigue of the passenger can also be solved, the image display effect is ensured, and better visual experience is provided for the passengers.

[0057] In some embodiments, based on the advantage that the light waveguide 21121 has in realizing complex optical functions in a small space, the light waveguide 21121 is suitable for being integrated in the projection module 21. In addition, since the image generation unit 2111, the control board 2114, and the light waveguide 21121 included in the projection module 21 all have the characteristic of small volume, the overall volume of the projection module 21 is small, thereby facilitating direct integration on the sun visor body 20, so that the vehicle can perform image presentation through the projection module 21 on the sun visor assembly 2. In this way, the position advantage of the sun visor located in front of the passengers can be fully utilized.

[0058] It should be noted that the projection module 21 with small overall volume can not only solve the problem in the related art that the aesthetic appearance of the vehicle interior is affected due to the integration of a large-sized image display module on the sun visor of the vehicle, but also can be applied to the windshield or other positions of the vehicle without limitation, and can be adjusted based on different application scenarios. The present disclosure does not limit this.

[0059] In some embodiments, the eye movement tracking technology can also be added in the projection module 21, so that the passenger can freely watch the image from multiple angles, and the viewing angle is more free and unrestricted, avoiding the limitation that the image can only be watched at a specific angle.

[0060] In some embodiments, the driving information contained in the first image displayed by the projection module 21 can include at least one of vehicle state information, driving environment information, and multimedia information. The driving environment information can be configured to indicate a driving blind area. In this way, the vehicle state information, the driving environment information configured to indicate the driving blind area of the vehicle, and the multimedia information are presented by the projection module 21 on the sun visor body 20, which can improve the driving safety of the vehicle, and the image generated based on the foregoing light waveguide imaging technology has stronger reality, larger information amount, and wider application range.

[0061] In some embodiments, the driving environment information has a higher display priority than the vehicle status information and the multimedia information. That is, among the driving environment information, the vehicle status information and the multimedia information, the driving environment information has the highest display priority.

[0062] For example, in the case that there is a driving danger in the blind area of the vehicle, the first image includes the driving environment information. After the driving danger ends, the first image includes at least one of the vehicle status information or the multimedia information.

[0063] Referring to FIG. 6, a flowchart of an image display method according to some embodiments is shown, which involves the sun visor assembly 2 shown in FIG. 2, and the method can include the following steps S601-S602.

[0064] Step S601, acquiring driving information.

[0065] The driving information can include at least one of the vehicle status information, the driving environment information and the multimedia information. The driving environment information can be configured to indicate the blind area. In order to improve the driving safety of the vehicle, the driving environment information is displayed in priority to the vehicle status information and the multimedia information.

[0066] In actual applications, the driving information can be collected or acquired by a vehicle terminal, such as a central controller. In order to enable the projection module 21 integrated on the sun visor body 20 to present the first image containing the driving information, the vehicle terminal can transmit at least one of the collected or acquired image information or the driving information to the projection module 21. During the information transmission process, the image information and the driving information are mainly transmitted in the form of electrical signals, that is, the image signal can be an electrical signal containing at least one of the image information or the driving information, at this time the vehicle terminal can transmit the image signal containing at least one of the image information or the driving information to the projection module 21. The collected or acquired image information can be configured to indicate some or some driving information.

[0067] Step S602, displaying the first image containing the driving information by the projection module arranged on the sun visor body.

[0068] After receiving the image signal containing at least one of the image information or the driving information transmitted by the vehicle terminal, the projection module 21 can generate an optical image signal containing the driving information based on the image signal by the image generation unit 2111, so as to realize image presentation in the sun visor projection system 100.

[0069] The image signal can be an electrical signal containing at least one of image information or driving information. For example, the image generation unit 2111 can be controlled by the control board 2114 to generate an optical image signal containing driving information based on an electrical signal containing driving information. For example, the image generation unit can be controlled by the control board 2114 to receive an electrical signal containing driving information, and then convert the electrical signal containing driving information into an optical signal by the image generation unit 2111, and convert the optical signal into an optical image signal containing driving information. The generated optical image signal is the optical image signal corresponding to the first image containing driving information.

[0070] The image generation unit 2111 can include an electrical signal input module 21111, an optical modulation module 21112, and an optical output module 21113. The generation process of the optical image signal can be, for example, receiving an electrical signal containing driving information through the electrical signal input module 21111, then converting the electrical signal into an optical signal through the optical modulation module 21112, and converting the optical signal into an optical image signal corresponding to the first image through the optical output module 21113.

[0071] The projection module 21 is a light waveguide projection module 211, which can include the above-mentioned image generation unit 2111 and a projection display unit 2112. The image generation unit 2111 can generate a first image according to driving information, and the projection display unit 2112 can mainly display the first image. In actual application, the projection display unit 2112 can be a light waveguide 21121.

[0072] After the optical output module 21113 outputs the visible optical image signal, a virtual image of the optical image signal can be displayed on the light waveguide 21121, that is, the first image containing driving information is displayed through the light waveguide 21121.

[0073] The light waveguide 21121 can be a holographic light waveguide or a diffractive light waveguide. The light waveguide 21121 has the advantages of high adjustability, high integration, low loss, and low crosstalk. The light waveguide can modulate and manipulate the interference pattern of light, flexibly control the propagation path and characteristics of light, and realize complex optical functions in a small space.

[0074] In actual applications, the projection module 21 can be located in front of the passenger seat. In some embodiments, the corresponding virtual image can be presented to the passenger by using the light waveguide imaging technology, for example, by using holographic imaging or diffraction imaging in the light waveguide imaging technology. For example, the vehicle projects the first image containing driving information to a virtual image beyond a preset distance in front of the vehicle through the projection module 21, so as to avoid the problem of visual fatigue of the passenger on the basis of fully utilizing the position advantage of the sun visor located in front of the passenger seat. The preset distance can be based on a test value or a theoretical value that can meet the comfort of the naked eye of the passenger, and is usually a preset value (in meters). The present disclosure does not limit this.

[0075] In some embodiments of the present disclosure, the first image containing driving information is displayed through the projection module 21 arranged on the sun visor body 20, so that the first image containing driving information is displayed through the projection module 21 integrated on the sun visor, thereby the position advantage of the sun visor located in front of the passenger seat can be utilized to display the image information without any interference to the normal line of sight of the passenger, so as to avoid the problem of visual fatigue of the passenger and ensure the image display effect, thereby providing a better visual experience for the passenger.

[0076] In some embodiments of the present disclosure, the driving information contained in the first image can include at least one of vehicle state information, driving environment information, and multimedia information. The vehicle state information can be configured to indicate various data and indicators generated during the operation of the vehicle, so as to help the driver understand the current condition of the vehicle. The driving environment information can be configured to indicate the environmental information of the vehicle during driving, for example, the driving environment information is configured to indicate the driving blind area, and the driving environment information can be the image information of the vehicle driving blind area (i.e. the image information detected in real time). The multimedia information can refer to any multimedia information related to the entertainment mode. It should be noted that the driving information in some embodiments of the present disclosure can also include other vehicle-related information, and the present disclosure does not limit this.

[0077] In some embodiments, in order to improve the driving safety of the vehicle, the driving environment information is displayed in priority to the vehicle state information and the multimedia information.

[0078] Taking the display of the first image containing the driving environment information as an example, the driving environment information, for example, the image information of the vehicle driving blind area, can be presented through the projection module 21 arranged on the sun visor body 20, so that the passenger can know the situation of the blind area outside the vehicle in time and improve the driving safety.

[0079] For example, in the case that there is a driving danger in the blind area of the vehicle, the first image containing the driving environment information can be displayed by the projection display unit 2112 of the projection module 21. And after the driving danger ends, the first image containing at least one of the vehicle state information or the multimedia information can be displayed by the projection display unit 2112.

[0080] The projection module 21 can receive the image signal containing the vehicle blind area image information transmitted by the vehicle terminal. In actual application, the aforementioned image signal containing the vehicle blind area image information can be generated by the vehicle terminal based on the vehicle blind area image information when it is determined that the vehicle driving is dangerous, and then the image generation unit 2111 can be controlled by the control board 2114 to generate the optical image signal corresponding to the first image containing the vehicle blind area image information based on the image signal containing the vehicle blind area image information.

[0081] In some embodiments, the electrical signal input module 21111 can receive the electrical signal containing the vehicle blind area image information transmitted by the camera. The electrical signal can include the raw data of the vehicle blind area image captured by the camera. Then, the optical modulation module 21112 can process the electrical signal by controlling the intensity or phase of the electrical signal to change the characteristics of the light, thereby converting the electrical signal into an optical signal. The light output module 21113 can process the optical signal to convert it into a visible optical image signal. Finally, the first image can be presented by the projection display unit 2112 of the projection module 21, i.e. the optical waveguide 21121, so that the passengers can directly see the image of the environment around the vehicle. For example, it can be manifested as displaying a virtual image of the optical image signal corresponding to the vehicle blind area image information on the optical waveguide 21121.

[0082] In some embodiments, when the vehicle blind area image information is displayed by the projection display unit 2112 of the projection module 21, the projection module 21 can also receive the image display interruption signal transmitted by the vehicle terminal. In actual application, the image display interruption signal can be generated by the vehicle terminal when it is detected that the first image containing the multimedia information corresponding to the entertainment mode is displayed on the optical waveguide 21121. At this time, the first image containing the multimedia information displayed on the optical waveguide 21121 can be stopped to interrupt the currently displayed image information.

[0083] In some embodiments, when the vehicle blind area image information is displayed by the projection display unit 2112 of the projection module 21, the danger end signal transmitted by the vehicle terminal can also be received. In actual application, the danger end signal can be generated by the vehicle terminal when it is detected that the vehicle driving is safe, and then the first image containing the vehicle blind area image information displayed on the optical waveguide can be stopped.

[0084] In some embodiments, the vehicle terminal can further transmit an image display recovery signal when the projection display unit 2112 of the projection module 21 displays the image information of the blind area of the vehicle. In actual applications, the image display recovery signal can be generated by the vehicle terminal when it detects the generation of the danger end signal and determines that the image display interruption signal is sent to the projection module 21, and then the first image corresponding to the multimedia information can be presented on the optical waveguide 21121 to restore the image information that was interrupted before.

[0085] As shown in FIG. 7, the step of displaying the blind area image information by the sun visor assembly 2 can include the following S701-S711.

[0086] When the camera system controlled by the vehicle terminal is started (S701), the camera outside the vehicle body captures image information (S702). For example, the camera arranged on the vehicle body can capture the image of the blind area view during the driving of the vehicle in real time, and at this time the camera system can transmit the image information of the surrounding environment captured in real time to the vehicle terminal (for example, the central controller). Then S703 is performed, the central controller detects the image information of the blind area, for example, the image information of the blind area of the vehicle can be detected by the detection algorithm built in the central controller. And S704 is performed, to determine whether there is a dangerous situation during the driving of the vehicle.

[0087] In one case, if it is determined that there is a dangerous situation during the driving of the vehicle, the central controller can present the image information of the blind area to the passengers to issue a driving danger signal. In actual applications, the central controller can generate an image signal containing the image information of the blind area of the vehicle when it determines that there is a danger during the driving of the vehicle based on the image information of the blind area of the vehicle, and deliver the aforementioned image signal to the projection module 21, so that the control board 2114 controls the image generation unit 2111 to generate a virtual image of the optical image signal corresponding to the first image containing the image information of the blind area of the vehicle on the optical waveguide 21121, and present the first image.

[0088] In another case, S705, if it is determined that there is no dangerous situation during the driving of the vehicle, the camera outside the vehicle body arranged on the vehicle body can continuously capture image information, that is, continuously capture the image of the blind area view during the driving of the vehicle, and the central controller can continuously monitor and determine.

[0089] In some embodiments, before the central controller delivers the image signal containing the image information of the blind area of the vehicle to the projection module 21, the central controller can further determine whether the projection module is currently in an entertainment mode (S706). For example, it is determined whether the first image containing the multimedia information related to the entertainment mode is displayed on the optical waveguide 21121.

[0090] In one case, if it is detected that the optical waveguide 21121 displays the first image containing multimedia information related to the entertainment mode, it indicates that the projection module 21 is currently in the entertainment mode, at this time, the entertainment mode of the projection module needs to be paused (S707) to pause the current playing content. Then S708 is executed, the related dangerous information is displayed by the projection module to realize the reminding of the dangerous situation. In actual application, the central controller can generate an image display interruption signal when it is detected that the optical waveguide 21121 displays the first image containing multimedia information related to the entertainment mode, and deliver the aforementioned image display interruption signal to the projection module 21, so as to stop presenting the first image containing multimedia information on the optical waveguide 21121.

[0091] In another case, if it is detected that the optical waveguide does not display the first image containing multimedia information related to the entertainment mode (S709), it indicates that the projection module 21 is currently not in the entertainment mode, at this time, the reminding of the dangerous situation can be realized directly through the presentation process of the aforementioned vehicle driving blind area image information.
