The singular forms "a", "said" and "the" used in the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0045] It should be understood that although the terms first, second, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, a first parameter may also be referred to as a second parameter, and similarly, a second parameter may also be referred to as a first parameter. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0046] It should be noted that in the relevant steps of the collection of user operations (such as receiving user input operations) involved in this application, the control system can display a prompt interface, pop-up window on the vehicle instrument, user application (Application, APP), etc., or broadcast voice prompt information. The prompt interface, pop-up window, and voice prompt information are used to prompt / inform the user that the user operation is currently being received. After obtaining the user's consent instruction (such as the user's confirmation operation triggered by the prompt interface or pop-up window), the control device can start to execute the relevant steps of receiving the user's input operation. Otherwise, the relevant steps of receiving the user's input operation are terminated, that is, the user's input operation is not received. In other words, the user's input operations received by this application are collected with the user's full knowledge, consent and authorization, and the collection, use, analysis and processing of relevant user data comply with the relevant laws, regulations and standards of relevant countries and regions.

[0047] To facilitate understanding, some concepts involved in this application are explained below.

[0048] 1) Head-Up Display System: Also known as Head-Up Display (HUD), it can project important driving information such as vehicle speed, navigation, and traffic lights onto reflective surfaces such as the windshield in front of the driver, allowing the driver to see important driving information such as speed, navigation, and traffic lights without lowering or turning his head.

[0049] 2) Controls: refers to the elements used for user interaction on the display interface of a touch screen, display screen, etc., such as buttons, sliders, lists, text boxes and other graphical user interface (GUI) components, which enable users to easily control the vehicle's functions and services.

[0050] 3) People with color vision abnormalities: Normal people have three types of cones in their eyes, corresponding to red, green, and blue, respectively. People with color vision abnormalities may lack certain cones, or these cones may function abnormally, resulting in the inability to distinguish one or several colors. For people with red color deficiency, red and green look similar and difficult to distinguish, which means that in traffic lights, red and green lights may look very similar.

[0051] Please refer to Figure 1 , which shows a schematic diagram of an implementation environment of an information prompt method for a vehicle provided by an exemplary embodiment of the present application. Figure 1 As shown, the implementation environment may include: a vehicle 110, and optionally, a server 120, wherein the vehicle 110 includes a vehicle system 110a and a head-up display system 110b.

[0052] The above-mentioned vehicle system 110a can be a touch screen device that integrates multiple vehicle functions such as infotainment, navigation, vehicle settings, and mobile phone interconnection. Users can interact with the vehicle through the vehicle system 110a. For example, the vehicle system 110a includes a multimedia entertainment screen or a multimedia display screen, and users can start the vehicle's navigation and other services by clicking on the specified controls of the multimedia display screen; for another example, the vehicle system 110a includes a voice and / or gesture processing module, and users can control the automatic lifting and lowering of the car windows, the automatic opening and closing of the trunk, etc. through specified voice commands and / or specified gesture commands; for another example, the vehicle system 110a includes a wireless communication module, and users can start the vehicle, find the vehicle location, etc. through mobile phone applications.

[0053] In the embodiment of the present application, a client running a target application may be installed in the vehicle system 110a, and the target application may be an application having functions of receiving and responding to user operations, sending instructions, etc. The present application does not limit the form of the target application.

[0054] The head-up display system 110b can be connected to a central controller bus. The vehicle system 110a can be integrated into the vehicle's central controller. That is, the user can control the head-up display system 110b through the vehicle system 110a; for example, the user can start the head-up display system 110b, switch the type of information displayed in the head-up display system 110b, etc., by specifying controls, specifying voice commands, specifying gesture commands, or other methods, so that the traffic light conditions of the road section where the vehicle is located can be displayed on the windshield in front of the driver.

[0055] The server 120 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud platform, cloud server, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, content delivery network (CDN), and cloud server for basic cloud computing services such as big data and artificial intelligence platform. Among them, the cloud server of big data and artificial intelligence platform can provide artificial intelligence cloud service. Server 120 may be the background server of the target application, used to provide background service for the client of the target application.

[0056] Among them, the vehicle 110 and the server 120 can be directly or indirectly connected through a communication network 130 (wired network or wireless network), which is not limited in this application. Optionally, the above-mentioned communication network 130 can be a wired network, such as Ethernet, diagnostic protocol; or, the above-mentioned communication network 130 can also be a wireless network, such as a cellular network, satellite communication, and vehicle-to-everything (V2X). The above-mentioned communication network 130 can be used alone or in combination to provide various data transmission, communication and Internet connection functions for the vehicle, thereby realizing a more intelligent and convenient driving and riding experience.

[0057] For example, in Figure 1 In the system shown, the vehicle system 110a can receive the user's input operation, and according to the received input operation, send a corresponding indication signal to the head-up display system 110b. For example, the user can click on the first control for starting the head-up display system 110b on the display interface of the vehicle system 110a; accordingly, the vehicle system 110a sends a first signal to the head-up display system 110b; the head-up display system 110b displays the signal light information of the normal mode on the windshield in front of the driver according to the first signal, and the signal light information is used to indicate the signal light status of the road section where the vehicle is located. For another example, the user can click on the second control for switching the display color on the display interface of the vehicle system 110a; accordingly, the vehicle system 110a sends a second signal to the head-up display system 110b; the head-up display system 110b switches the normal mode to the specified mode according to the second signal, and the specified mode enables people with abnormal color vision to distinguish the signal lights.

[0058] Please refer to Figure 2 , which shows a flow chart of an information prompt method for a vehicle provided by an exemplary embodiment of the present application. The method can be executed by a vehicle, and the vehicle includes a vehicle system and a head-up display system. Optionally, the vehicle can be Figure 1 The vehicle 110 in the system shown. Figure 2 As shown, the method may include step 210 , step 220 , and step 230 .

[0059] Step 210: Receive user input operations through the vehicle system.

[0060] That is to say, the user can interact with the vehicle system through different input operations. Accordingly, the developer can set a variety of input operations for different interactions between the user and the vehicle system, and the multiple input operations enable the user to conveniently control the vehicle.

[0061] Exemplarily, the above input operation may include one or more of the following operations:

[0062] 1) Touch screen or display trigger operation: users can directly click, slide or drag on the touch screen or display screen to control music playback, navigation, phone and other vehicle functions;

[0063] 2) Physical button or knob trigger operation: Users can control vehicle functions by pressing physical buttons or twisting knobs; physical buttons or knobs can be used to quickly access common functions, such as volume control, menu option scrolling, setting adjustment, etc.;

[0064] 3) Voice command: The vehicle system can support voice recognition, allowing users to control vehicle functions such as music playback, navigation, and phone calls through voice commands, which helps reduce the user's manual operation and improve driving safety and convenience;

[0065] 4) In-air gestures: The vehicle system can support gesture recognition, allowing users to control one or more vehicle functions through in-air gestures, such as adjusting seats, starting air conditioning, etc.;

[0066] 5) Remote control operation: The vehicle system can remotely control one or more vehicle functions through a matching mobile phone application, such as remote start, finding the vehicle location, etc.

[0067] Step 220: When a first input operation is received, a first signal is sent to the head-up display system through the vehicle system; the first signal is used to instruct the head-up display system to display signal light information of a first mode on the reflective surface; the signal light information is used to indicate the signal light condition of the road section where the vehicle is located.

[0068] The first input operation is one or more of the above input operations. For example, the user can control the head-up display system to display the signal light information of the first mode on the reflective surface by specifying a voice command.

[0069] The signal light information may include the road section where the vehicle is located, the pattern information of the signal light in the current driving direction, whether it is red, green or yellow, and optionally, the display duration of the current signal light, such as the countdown information of the red, green or yellow light. Figure 3 , which shows a schematic diagram of a head-up display system display interface provided by an exemplary embodiment of the present application; Figure 3 As shown in part (a) of FIG. 3 , the reflective surface 310 displays a current left-turn signal light pattern 301 and a left-turn signal light countdown 302 .

[0070] Among them, in the above-mentioned first mode, the signal light information (such as patterns, countdown) can be displayed in normal colors.

[0071] Exemplarily, the head-up display system may also display other vehicle driving information on the reflective surface. For example, the other driving information may include one or more of the following: vehicle speed information, road speed limit information, fuel level information, battery level information, road navigation information, vehicle interior temperature information, vehicle exterior temperature information, etc.

[0072] Optionally, the first signal is also used to start the head-up display system. For example, when the first input operation is received and it is detected that the head-up display system is not started, the vehicle system sends the first signal to the head-up display system; accordingly, the head-up display system starts and displays the signal light information of the first mode on the reflective surface according to the first signal.

[0073] The above-mentioned reflective surface may be the front windshield of the vehicle, or a resin plate installed in front of the driver's line of sight.

[0074] In a possible implementation, after receiving the first signal and displaying the signal light information of the first mode on the reflective surface, the head-up display system may send a first feedback signal to the vehicle system, and the first feedback signal is used to indicate that the head-up display system has displayed the signal light information of the first mode on the reflective surface; accordingly, the vehicle system may transmit the first feedback information to the user. For example, the vehicle system displays the specified identification information on the display interface; for another example, the vehicle system broadcasts the specified voice package to the user. Specifically, for example, the identification information displayed by the vehicle system on the display interface may be text information such as "HUD enters normal display mode", or it may be icon information representing the meaning of HUD entering normal display mode, and the voice package broadcast by the vehicle system may be "HUD enters normal display mode" or similar content.

[0075] Step 230: When receiving the second input operation, a second signal is sent to the head-up display system through the vehicle system; the second signal is used to instruct the head-up display system to display the second mode of signal light information on the reflective surface, and the second mode is used to enable people with color vision abnormalities to distinguish signal lights. The second input operation is one or more of the above input operations. For example, the user can control the head-up display system to display the second mode of signal light information on the reflective surface by specifying an air gesture.

[0076] In the second mode, the signal light information (such as patterns and countdown) can be displayed in a different color from that in the first mode, so that people with color vision abnormalities can correctly distinguish the signal light. For example, the contrast and saturation of the colors in the second mode can be higher than those in the first mode.

[0077] For example, in the second mode, the signal light information may include not only the pattern information of the road section where the vehicle is located and the signal light in the current driving direction being red, green or yellow, but also the text information of the road section where the vehicle is located and the signal light in the current driving direction being red, green or yellow. Figure 3 As shown in part (b) of FIG. 3 , the reflective surface 320 displays a current left turn signal light pattern 303 , a current left turn signal light text 304 , and a left turn signal light countdown 305 .

[0078] Optionally, the pattern shape of the traffic light displayed in the second mode can indicate the road section where the vehicle is located, and whether the traffic light in the current driving direction is red, green or yellow. For example, the pattern shape corresponding to the red light is a circle, the pattern shape corresponding to the green light is a triangle, and the pattern shape corresponding to the yellow light is a square.

[0079] Optionally, the vehicle can provide users with editing permissions for the second mode, that is, the second mode can be a mode preset by the user. For example, before the vehicle is driven, the user edits the type, color, pattern, text, etc. of information displayed in the second mode on the display interface of the vehicle system. For example, users with red and green color deficiency can adjust the contrast and saturation of the red and green colors displayed by the head-up display system to a clearly distinguishable level; or change the pattern shape of the signal light displayed by the head-up display system to a clearly distinguishable shape. Please refer to Figure 4 , which shows a schematic diagram of a head-up display system editing interface provided by an exemplary embodiment of the present application; Figure 4 As shown, the upper part of the editing interface 410 displays the editing options of the red light, green light, and yellow light, and the lower part displays the preview effect after editing; the user can customize the contrast, saturation, display shape, and whether to display text of the red light, green light, and yellow light.

[0080] In a possible implementation, after receiving the second signal and displaying the signal light information of the second mode on the reflective surface, the head-up display system may send a second feedback signal to the vehicle system, and the second feedback signal is used to indicate that the head-up display system has displayed the signal light information of the second mode on the reflective surface; accordingly, the vehicle system may transmit the second feedback information to the user. For example, the vehicle system displays the specified identification information on the display interface; for another example, the vehicle system broadcasts the specified voice package to the user. Specifically, for example, the identification information displayed by the vehicle system on the display interface may be text information such as "HUD enters the color-weak display mode", or it may be icon information representing the meaning of HUD entering the color-weak display mode, and the voice package broadcast by the vehicle system may be "HUD enters the color-weak display mode" or similar content.

[0081] In a possible implementation, when the vehicle system receives an input operation from the user, the vehicle system may send a corresponding signal to the body controller BCM; then, the BCM may send the signal to the head-up display system.

[0082] To summarize, according to the solution shown in the embodiment of the present application, the vehicle system can provide the user with the function of changing the display mode of the head-up display system. During the driving of the vehicle, the user can implement the switching operation of the display mode of the head-up display system in the vehicle system through pre-set voice or touch operations; that is, the user can change the mode of displaying signal light information of the head-up display system to a mode that can be distinguished by users with weak red and green colors through simple voice or touch operations, thereby improving the safety of the vehicle driving process.

[0083] Based on the above Figure 2 In the solution in the embodiment shown, in a possible implementation solution, the vehicle further includes a seat control system; the above-mentioned information prompt method for the vehicle further includes:

[0084] When the second input operation is received, a third signal is sent to the seat control system through the vehicle system; the third signal is used to instruct the seat control system to transmit prompt information to the user, and the prompt information is used to indicate the traffic light status of the road section where the vehicle is located.

[0085] The prompt information may be transmitted in the form of one or more of voice broadcast and seat vibration.

[0086] In other words, the seat control system can support the function of interactive prompts, that is, it can provide prompt information to the user based on the third signal from the vehicle system; for example, it can inform the driver of the current traffic light status through vibration, sound, etc. Accordingly, the seat control system needs to have a certain hardware foundation and software logic; for example, the seat needs to be equipped with a device that can generate vibration or sound, as well as an electronic control unit (ECU) that can receive and analyze vehicle system signals.

[0087] Exemplarily, when the second input operation is received, the vehicle system can carry in the third signal information indicating whether the signal light for the current direction of travel is red, green or yellow, depending on the signal light condition indicated by the navigation information; accordingly, the seat control system can transmit corresponding prompt information to the user according to the signal light indicated by the third signal; for example, when the vehicle is on the road section and the signal light for the current direction of travel is red, the vibration device is activated to remind the driver.

[0088] Exemplarily, the seat control system may also support one or more of the following functions:

[0089] Massage function: can reduce user fatigue during long-distance driving, parking and resting;

[0090] Electric adjustment: allows users to adjust the position of the seat through buttons or knobs, including forward and backward movement, up and down movement, tilt angle, etc.;

[0091] Memory function: Ability to store one or more preset seat positions so the driver can quickly return to a previously set position;

[0092] Heating and ventilation: The seats are heated in cold weather and ventilated in hot weather to improve riding comfort;

[0093] Safety features: Seats can be equipped with active safety features, such as seat airbags, pre-tensioned seat belts, etc., to improve safety in the event of a collision.

[0094] In an embodiment of the present application, when the user triggers the second input operation, the seat control system can inform the user of the traffic light conditions of the road section where the vehicle is currently located through prompt information; for example, the seat control system can inform the user whether the current traffic light is red or green by means of seat vibration; this solution can use methods such as seat vibration of the seat control module to promptly convey the traffic light conditions to the user, thereby further improving the user's vehicle safety.

[0095] Based on the above Figure 2In the scheme of the embodiment shown, in a possible implementation scheme, the seat control system includes one or more of a voice broadcast unit and a seat vibration unit; the prompt information includes one or more of a prompt voice and a seat vibration;

[0096] The third signal is also used to instruct the voice broadcast unit to broadcast the prompt voice to the user;

[0097] The third signal is also used to instruct the seat vibration unit to initiate seat vibration to the user.

[0098] Exemplarily, the seat control system may include an electronic control unit ECU, a voice broadcast unit, and a seat vibration unit, wherein the electronic control unit ECU can not only receive and analyze vehicle system signals, but also control the voice broadcast unit and the seat vibration unit to perform corresponding vehicle functions.

[0099] The above-mentioned prompt voice may include one or more of the current traffic light status, waiting time, and passing time.

[0100] Optionally, the above-mentioned voice broadcast unit can use bone conduction technology to transmit the prompt voice to the user. That is to say, the above-mentioned voice broadcast unit can be implemented as a seat bone conduction voice broadcast unit, so that even if the user does not use headphones, the user can hear the sound that only the user can hear; at the same time, when the vehicle environment is noisy (such as when the vehicle audio is in use), the signal light information can also be heard in time. Among them, bone conduction technology can convert sound signals into vibrations through the vibration unit in the seat, and then transmit them to the inner ear through the user's bones, so that the user can hear the voice information. Specifically, first, the voice information is converted into an electrical signal, and the electrical signal is converted by the bone conduction vibration unit in the seat; secondly, the bone conduction vibration unit converts the electrical signal into mechanical vibration, which is transmitted to the user's head or neck bones through the seat; then, the vibration propagates along the user's bones to the inner ear, and the auditory organ of the inner ear converts the vibration into understandable sound.

[0101] Among them, the vibration intensity, frequency and duration of the seat vibration unit can be pre-set by the user. Exemplarily, multiple vibration sub-units can be set in the seat of the vehicle to achieve functions such as safety prompts, navigation guidance, massage and relaxation. Optionally, the above-mentioned seat vibration unit can be a device that can provide tactile feedback, such as multiple vibration motors. Specifically, during driving, the electronic control unit ECU of the seat control system can control the seat vibration unit to perform vibrations of specified intensity, frequency and duration to provide safety prompts to the driver; for example, when approaching a red light, the seat can vibrate to remind the driver. In addition, the seat can also vibrate to indicate to the driver when to turn or change lanes; for example, the vibration of the left vibration sub-unit indicates a left turn, and the vibration of the right vibration sub-unit indicates a right turn.

[0102] Optionally, on the road section where the vehicle is located, when the traffic light in the current driving direction is red, the vibration intensity and frequency of the seat vibration unit can be larger and the duration is longer; when the traffic light in the current driving direction is green, the vibration intensity and frequency of the seat vibration unit can be smaller and the duration is shorter, so that the user can clearly distinguish the situations of different traffic lights according to the differences in the vibration intensity, frequency and duration of the seat vibration unit.

[0103] An embodiment of the present application provides a specific method for a seat control system to transmit prompt information to a user. A voice broadcast unit and a seat vibration unit are provided in the seat control system, which are respectively used to broadcast a prompt voice of the traffic light status to the user and to initiate seat vibration corresponding to the traffic light. This solution transmits the traffic light status to the user through direct methods such as voice broadcast and seat vibration, thereby further improving the user's vehicle safety without interfering with driving operations.

[0104] Based on the solutions shown in the above embodiments of the present application, in a possible implementation scheme, the vehicle further includes a gear control system; and the method further includes:

[0105] When it is detected that the gear position of the vehicle meets the specified conditions, a fourth signal is sent to the seat control system through the gear control system; the fourth signal is used to instruct the seat control system to cancel the transmission of prompt information to the user.

[0106] Among them, the above-mentioned gear control system can monitor the current gear status of the vehicle, including forward gear, driving gear (D gear), parking gear (P gear), neutral gear (N gear), etc.

[0107] Exemplarily, the above-mentioned gear control system can send the gear status of the vehicle to the vehicle controller VCU, and then the vehicle control system VCU sends the gear status of the vehicle to the body controller BCM, and the BCM can send the gear status of the vehicle to the seat control system. The ECU of the seat control system determines whether to cancel the prompt information to the user according to the gear status of the vehicle and the condition of the traffic lights.

[0108] For example, when the traffic light on the road section where the vehicle is located is red, the seat control system can inform the user through seat vibration and voice broadcast. When the vehicle's gear position is detected to be N gear, the seat control system can cancel the seat vibration and voice broadcast. For another example, when the traffic light on the road section where the vehicle is located is green, the seat control system can inform the user through seat vibration and voice broadcast. When the vehicle's gear position is detected to be forward gear or D gear, the seat control system can cancel the seat vibration and voice broadcast.

[0109] In an embodiment of the present application, the vehicle can determine whether the driver has correctly received the prompt information transmitted by the seat control system based on the driver's gear shifting operation; for example, when the traffic light on the road section where the vehicle is located is red, the seat control system can inform the user through seat vibration. When it is detected that the vehicle's gear position is N gear, the seat control system can cancel the seat vibration, thereby reducing unnecessary tactile feedback and improving user experience.

[0110] Based on the solutions shown in the above embodiments of the present application, in a possible implementation scheme, the first input operation is a voice input operation corresponding to the first voice command, or a triggering operation on a designated area of ​​the vehicle system;

[0111] The second input operation is a voice input operation corresponding to the second voice command, or a triggering operation on a specified control in a specified application interface.

[0112] Exemplarily, the voice input operation corresponding to the first voice command may be a voice command issued by the user such as “HUD displays the traffic lights in normal mode”, indicating the intention to view the traffic lights in normal mode through the reflective surface of the HUD; the voice input operation corresponding to the second voice command may be a voice command issued by the user such as “HUD displays the traffic lights in color weakness mode”, “I can't see the traffic lights ahead clearly”, indicating the intention to change the HUD display mode.

[0113] Among them, the above-mentioned triggering operation on the designated area of ​​the vehicle system can be a triggering operation of a physical button or knob, a triggering operation of a touch screen or display screen, or an air gesture in the video camera area.

[0114] In an embodiment of the present application, the user can interact with the vehicle system through voice commands or touch operations.

[0134] Please refer to Figure 5, which shows a flow chart of an information prompt method for a vehicle provided by an exemplary embodiment of the present application. The vehicle includes a vehicle system, a head-up display system, a seat control system, and a gear control module, such as Figure 5 As shown, a vehicle information prompting method includes the following steps:

[0135] Step 501: receiving a user's input operation through the vehicle computer system;

[0139] Among them, the execution method of step 501 to step 504 is the same as the execution method of the above-mentioned embodiments of the present application, and will not be repeated here.

[0140] Based on any one or more of the above embodiments, the embodiments of the present application propose a method and system for assisting people with color blindness to judge traffic light signals, mainly to solve the problem in the related art that during vehicle driving, people with color blindness cannot correctly judge traffic lights, resulting in safety hazards during vehicle driving, thereby causing safety accidents.

[0141] like Figure 6As shown, the above-mentioned system for assisting color-blind people to judge traffic light signals includes a vehicle large screen module 601, and a head-up display system (Head Up Display, HUD) module 602, a body controller (Body Control Module, BCM) module 603, a right domain controller (Vehicle Control Center Module, VCCM) module 604, a seat bone conduction voice broadcast module 605, a seat vibration module 606, a gear control module 607, and a vehicle control (Vehicle Control Unit, VCU) module 608 connected to the vehicle large screen module 601 by a bus.

[0142] Among them, the HUD module 602 is used for the driver to identify the current traffic light status. For example, the HUD module 602 can display the current traffic light status and traffic light timing on the windshield in front of the driver based on the navigation information of the vehicle large screen module 601.

[0143] The vehicle large screen module 601 can receive a color weakness mode switching request from the user and send a color weakness mode trigger signal to the BCM module 603. The BCM module 603 can receive the color weakness mode trigger signal from the vehicle large screen module 601 and send the color weakness mode trigger signal to the VCCM module 604, which is forwarded by the VCCM module 604 to the HUD module 602, the seat bone conduction voice broadcast module 605, and the seat vibration module 606.

[0144] The seat bone conduction voice broadcast module 605 can cooperate with the HUD module 602 to broadcast the corresponding signal light and road conditions according to the navigation information of the vehicle large screen module 601. The seat vibration module 606 can cooperate with the HUD module 602 to perform corresponding seat vibration according to the navigation information of the vehicle large screen module 601. The gear control module 607 is mainly used to provide the driver's gear shifting information to the VCU module 608, and is used to instruct the seat bone conduction voice broadcast module 605 to cancel the corresponding signal light broadcast and road condition broadcast, and the seat vibration module 606 to cancel the corresponding seat vibration.

[0145] Exemplarily, the method for assisting color-blind people to judge traffic light signals comprises the following steps:

[0146] First, the vehicle large screen module 601 sends a color weakness mode trigger signal to the BCM module 603:

[0147] After receiving the driver's input operation to adjust the HUD display mode to the color weakness mode, the vehicle large screen module 601 sends a color weakness mode trigger signal to the BCM module 603; accordingly, the BCM module 603 forwards the color weakness mode trigger signal to the HUD module 602, the seat bone conduction voice broadcast module 605, and the seat vibration module 606 through the VCCM module 604.

[0148] Secondly, the HUD module 602 adjusts the display mode to the color-blind mode, that is, displays the signal light information of the color-blind mode:

[0149] When the HUD module 602 receives the color-blind mode trigger signal sent by the BCM module 603, the font color, traffic light graphic color, and countdown color displayed by the HUD module 602 will be changed accordingly to colors that can be recognized by color-blind people.

[0150] At the same time, the seat bone conduction voice broadcast module 605 performs voice broadcast, and the seat vibration module 606 performs seat vibration:

[0151] When the seat bone conduction voice broadcast module 605 receives the color weakness mode trigger signal sent by the BCM module 603, the seat bone conduction voice broadcast module 605 can make a voice broadcast through bone conduction according to the traffic light status and road conditions fed back by the navigation information of the current vehicle large screen module 601. The voice broadcast content may include the current traffic light status, waiting time, passing time, etc.

[0152] When the seat vibration module 606 receives the color-blind mode trigger signal sent by the BCM module 603, the seat vibration module 606 will perform corresponding seat vibration according to the color of the traffic light. For example, when the traffic light is red, the seat vibration module 606 can perform fast short-frequency vibration; when the traffic light is green, the seat vibration module can perform long-frequency vibration; in order to avoid misjudgment, when the traffic light is yellow, the seat vibration module does not vibrate.

[0153] The above is the principle of the method for helping people with color blindness to judge traffic light signals. The display mode of the HUD module 602 is changed through the vehicle large screen module 601, the traffic light status is displayed through the HUD module 602, and the signal status is notified to the driver through the seat bone conduction voice broadcast module 605.
