[0002] This application claims priority and benefits of patent application No. 202410210550.X filed with the State Intellectual Property Office of China on February 26, 2024, and the entire text of which is incorporated herein by reference. Technical Field

[0004] For vehicles equipped with a passenger airbag, the passenger airbag's disabled and enabled states are crucial to user safety. If a child is riding in the passenger seat, the airbag must be disabled to prevent it from deploying during a collision and potentially injuring the child. Conversely, if an adult is riding in the passenger seat, the airbag must be deployed to protect the adult during a collision. Therefore, both the passenger airbag's state setting and status indication carry functional safety attributes, typically requiring safety requirements for both the control switch and the status display.

[0005] Since physical buttons have certain safety attributes, in related technologies, the control switch for the passenger airbag status mostly adopts the control method of physical buttons, but the cost of physical buttons with safety attributes is relatively high.

[0059] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0060] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

In addition, the meaning of "and / or" appearing throughout the text is to include three parallel solutions. Taking "A and / or B as an example", it includes Solution A, or Solution B, or a solution in which both A and B are satisfied. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0062] With the trend toward intelligent devices, many physical buttons are integrated into displays for aesthetics. However, touchscreen displays are prone to accidental touch control, resulting in lower security. For physical buttons where security is less critical, the physical function is removed and integrated into the display, sacrificing functionality. However, the safety function of setting the vehicle's airbags cannot be ignored, so the industry has resorted to physical button control, failing to integrate them into the display.

[0063] The embodiment of the present application is used as an example to solve the above problem and proposes a passenger airbag status setting device, which eliminates the physical buttons and integrates the physical buttons into the display screen for control, and can ensure the safety of the airbag status setting.

[0064] Specifically, referring to Figure 1 , the passenger airbag status setting device includes a touchscreen display 2, a status setting module 3, a vehicle domain control unit 1, and an airbag control module 4. Optionally, the touchscreen display 2 is a display within the vehicle cockpit and has a touch function, allowing the user to input control commands / control information through the touchscreen display 2. Alternatively, the touchscreen display 2 also has a voice acquisition function, allowing the user to input control voice through the touchscreen display 2.

[0065] Optionally, the state setting module 3 is used to set the state of the passenger airbag. The state of the passenger airbag includes an enabled state and a disabled state. When the airbag is in the enabled state, the airbag deploys in the event of a collision to protect the passenger; when the airbag is in the disabled state, the airbag does not deploy in the event of a collision and remains in an unused state.

[0066] In this embodiment, the passenger airbag setting switch is integrated into the touchscreen display 2, triggering the setting of the passenger airbag status via the touchscreen display 2. Alternatively, a physical switch can be configured as the status setting module 3 and integrated into the touchscreen display 2. In this manner, the status setting module 3 generates a status setting signal based on a touch operation on the touchscreen display 2, and uses this status setting signal to set the passenger airbag status. Alternatively, the touchscreen display 2 is a large screen within the vehicle cockpit, and either the driver or the passenger can control the airbag via the touchscreen display 2.

[0067] In this embodiment, to improve the touch security of the touch screen 2 and prevent the state setting module 3 from being accidentally triggered, when the state setting module 3 generates a state setting signal through a touch operation on the touch screen 2, the state setting module 3 displays a verification window on the touch screen 2 for the user to touch. The state setting module 3 also generates a verification signal through the touch operation on the touch screen 2 and transmits the verification signal to the vehicle domain control unit 1. The verification signal is used to verify whether the state setting signal is authentic and valid or a false trigger. Optionally, in this embodiment, the validity period of the verification window of the touch screen 2 can be set to a first preset duration. If the user triggers the verification window within the first preset duration, the state setting module 3 generates a verification signal and transmits it to the vehicle domain control unit 1. If the user does not trigger the verification window within the first preset duration, the verification window closes and the user cannot trigger it again. In this way, the state setting module 3 will not generate a verification signal. If the state setting signal is triggered by the user by mistake, the probability of triggering the verification window again within the first preset duration is extremely low, thereby achieving safe control of false triggering. Optionally, in other embodiments, the verification window of the touch display screen 2 can be set to be valid until the end of this setting (that is, the valid time is greater than the first preset time length), and the user can trigger the verification window at any time. The status setting module 3 generates verification information when the verification window is triggered and transmits it to the vehicle domain control unit 1. In this case, the vehicle domain control unit 1 can verify whether the status setting signal is triggered by mistake.

[0068] Optionally, the vehicle domain control unit 1 is configured to receive the state setting signal, and when the verification signal is received within a first preset time period, determine that the state setting signal verification is successful.

[0069] Optionally, the vehicle domain control unit 1 processes the signal transmitted by the state setting module 3 as follows: when the vehicle domain control unit 1 receives the state setting signal, it sends the state setting signal to the airbag control module 4 and starts timing (either forward timing or countdown). If a verification signal is received within the first preset time period, it is determined that the verification at the vehicle domain controller has passed, and the verification signal is sent to the airbag control module 4. If a verification signal is received outside the first preset time period, it is determined that the verification at the vehicle domain controller has failed, and the verification signal is not sent to the airbag control module 4. In this way, the airbag state setting channel is closed, and the airbag state cannot be set. This prevents the state setting signal triggered by the user from being responded to, resulting in an incorrect setting of the airbag state, thereby improving the safety of the airbag state setting.

[0070] Optionally, the airbag control module 4 is connected to the vehicle domain control unit 1 and the passenger airbag respectively, and the airbag control module 4 is configured to receive the status setting signal, and when the verification signal is received within the second preset time period, the status of the passenger airbag is set according to the status setting signal.

[0071] The airbag control module 4 is used to control the state of the airbag, such as whether the airbag control module 4 controls the airbag to be in an enabled state or the airbag control module 4 controls the airbag to be in a disabled state. Optionally, in some embodiments, when the airbag control module 4 receives a state setting signal, it is also necessary to verify the authenticity of the state setting signal through a verification signal to further improve the setting control of the airbag state. The airbag control module 4 determines whether the time interval between the reception of the verification state setting signal and the verification signal meets a second preset time length. In this way, even if the verification of the vehicle domain control unit 1 is incorrect, the authenticity of the state setting signal can be re-verified by the airbag control module 4, further improving the safety of the airbag state setting.

[0072] Optionally, the first preset duration and the second preset duration are configured the same under normal circumstances. In special circumstances, according to needs, the first preset duration and the second preset duration may also be configured differently.

[0073] Optionally, the first preset duration can be measured based on the timing module 13 of the vehicle domain control unit 1 (which may or may not share the same timing module with the third preset duration described below), or by an external timing module. Similarly, the second preset duration can be measured based on the timing module of the airbag control module 4, or by an external timing module. Optionally, the timing module communicates with the touch screen display 2 to display the timing process of the timing module on the display.

[0074] Alternatively, in other embodiments, the airbag control module 4 may not need to verify and directly set the state of the passenger airbag upon receiving the state setting signal.

[0075] Setting the passenger airbag status is also a status modification. For example, if the passenger airbag status is set to disabled, the passenger airbag status is modified from enabled to disabled; if the passenger airbag status is set to enabled, the passenger airbag status is modified from disabled to enabled.

[0076] Optionally, in some embodiments, the setting of the passenger airbag status can be achieved by modifying the control switch of the passenger airbag, or by modifying the passenger airbag control program.

[0077] In this embodiment, the state setting module 3 is integrated into the touch display screen 2, and when the state setting module 3 generates a state setting signal, the verification of the state setting signal is triggered, and after the automobile domain control unit 1 and the airbag control module 4 successfully verify the state setting signal based on the verification signal, the state setting signal is responded to. In this way, the state setting physical button is cancelled and integrated into the touch display screen 2, thereby ensuring the safety attributes of the state setting module 3 on the touch display screen 2 and preventing the airbag control module 4 from responding to erroneous triggering instructions.

[0078] In some optional embodiments, the state setting module 3 includes a state setting control 31 and a setting verification control 32 .

[0079] Among them, the status setting control 31 is displayed on the touch display screen 2, and the user can trigger the status setting control 31 by a trigger operation of the touch display screen 2, so that the status setting control 31 generates a status setting signal; the status setting control 31 is connected to the vehicle domain control unit 1, and after the status setting control 31 generates the status setting signal, the status setting signal is transmitted to the vehicle domain control unit 1 so that the vehicle domain control unit 1 executes the status setting signal.

[0080] The setting verification control 32 is in communication with the state setting control 31 . When the state setting control 31 generates a state setting signal, the setting verification control 32 is triggered, so that the setting verification control 32 is displayed on the touch screen 2 .

[0081] In this embodiment, when the setting verification control 32 is triggered, it is displayed on the touch screen display 2 (e.g., an input window for the setting verification control 32 is displayed on the display, or an identifier for the setting verification control 32 is displayed, such as text, an icon, a video, or an audio signal). When the setting verification control 32 is displayed on the touch screen display 2, the user can trigger the setting verification control 32 by touching the display 2, and the setting verification control 32 generates a verification signal. The setting verification control 32 is connected to the vehicle domain control unit 1 and transmits the verification signal to the vehicle domain control unit 1.

[0082] In this embodiment, in order to improve the safety of the passenger airbag setting, the validity period of the verification signal generated by the configuration setting verification control 32 is set. If the user triggers the setting verification control 32 within the first preset time after triggering the status setting control 31, the time interval between the generation of the status setting signal and the verification signal is less than or equal to the first preset time. In this way, when the status setting module 3 and the vehicle domain control unit 1 communicate normally, after the vehicle domain control unit 1 receives the status setting signal, it will receive the verification signal within the first preset time. In this way, the vehicle domain control unit 1 can determine that the status setting signal is the setting expected by the user.

[0083] This embodiment uses the status setting control 31 and the setting verification control 32 to manually confirm again based on the setting status, and then the system sets the passenger airbag, thereby improving the safety of the passenger airbag status setting and compensating for the unsafe defects of the display screen touch.

[0084] In some optional embodiments, the vehicle domain control unit 1 includes: a battery status management module 11 and a processing module 12, the battery status management module 11 is connected to the status setting module 3, and the processing module 12 is connected to the battery management status and the airbag control module 4 respectively;

[0085] The battery status management module 11 is configured to send the status setting signal to the processing module 12 upon receiving the status setting signal; and send the verification signal to the processing module 12 upon receiving the verification signal within a first preset time period;

[0086] The processing module 12 is configured to send the state setting signal to the airbag control module 4 when receiving the state setting signal; and send the verification signal to the airbag control module 4 when receiving the verification signal within a first preset time period.

[0087] Optionally, the processing module 12 is equivalent to a central processing unit.

[0088] When this embodiment is applied in the field of electric vehicles, the airbag can be controlled based on the battery status management module 11 in combination with the usage of the vehicle, thereby improving the safety of the airbag status setting.

[0089] In an optional embodiment, the passenger airbag state setting device further includes a prompt module 5, and the prompt module 5 is connected to the vehicle domain control unit 1;

[0090] The airbag control module 4 is further configured to feed back a setting completion signal to the vehicle domain control unit 1 after successfully setting the state of the passenger airbag;

[0091] The vehicle domain control unit 1 is further configured to output a setting completion prompt instruction after receiving the setting completion signal;

[0092] The prompt module 5 is configured to output prompt information corresponding to the setting completion prompt instruction when receiving the setting completion prompt instruction fed back by the vehicle domain control unit 1.

[0093] In this embodiment, after the airbag control module 4 sets the status of the passenger airbag, it returns a setting completion signal, which is then sent to the user via the prompt module 5 to inform them of the current status of the passenger airbag. If the current status is not what the user expects, the user can promptly modify the passenger airbag status based on the prompt. If the current status is what the user expects, the prompt allows the user to confirm that the passenger airbag status meets their expectations and that they can drive safely.

[0094] Optionally, in this embodiment, the prompt module 5 may provide a prompt indicating that the setting is complete, or a prompt indicating that the setting is unsuccessful. If the airbag control module 4 fails to set the passenger airbag, it will also provide a feedback signal indicating that the setting is not complete. The vehicle domain control unit 1 then outputs a prompt indicating that the setting is not complete, and the prompt module 5 then provides a corresponding prompt indicating that the setting is not complete.

[0095] Optionally, in this embodiment, the prompt module 5 is provided on the touch display screen 2 , and / or the prompt module 5 is provided on an instrument 6 of the vehicle.

[0096] In a preferred embodiment, the prompt module 5 is installed on both the touch screen display 2 and the vehicle's instrument panel 6, and the prompt modules 5 in both locations are independently connected to the vehicle domain control unit 1. Prompt information is transmitted via two communication links. If one link fails or is delayed, the other link can promptly notify the user of the passenger airbag setting, improving the touch screen display 2's setting effect and enhancing the user experience.

[0097] In an optional embodiment, the device further includes a timing module 13, the timing module 13 being connected to the vehicle domain control unit 1, and the timing module 13 being configured to start timing for a third preset time period based on the vehicle domain control unit 1 receiving the verification signal within the first preset time period;

[0098] The vehicle domain control unit 1 is further configured to output an expected setting completion prompt instruction when the setting completion signal is received within the third preset time period; and output an unexpected setting completion prompt instruction when the setting completion signal is received after the third preset time period has expired.

[0099] In this embodiment, the time between receiving the verification signal and receiving the feedback completion signal is set based on the airbag control module 4's response speed to the state setting signal and the duration of the normal feedback completion signal. If this time is exceeded, the state setting signal may not be what the user expected, and a corresponding prompt message is output to alert the user, facilitating prompt detection. Based on this, the vehicle domain control unit 1 in this embodiment determines whether the state setting signal represents an expected modification based on the time interval between receiving the completion signal and the verification signal. If not, the user is alerted that the modification was unexpected. If so, the user is informed that the system completed the modification as expected, thereby improving the security of state setting.

[0100] Optionally, in some embodiments, to further improve the safety of the passenger airbag state setting and avoid a mismatch between the set state and the safety protection of the passenger seat, such as when the user sets the disabled state but the passenger seat is an adult, or when the user sets the enabled state but the passenger seat is in a child seat, the apparatus proposed in this embodiment further includes a passenger detection module, which is connected to the vehicle domain control unit 1 or the airbag control module 4 and is configured to send a detection result of the child seat on the passenger seat to the vehicle domain control unit 1 or the airbag control module 4.

[0101] Alternatively, in some embodiments, the passenger detection module is connected to the vehicle domain control unit 1, and the vehicle domain control unit 1 triggers the state setting module 3 to automatically generate a state setting signal, thereby automatically triggering the state setting. For example, if a child seat is detected in the passenger seat, the state setting module 3 is triggered to disable the airbag. If no child seat is detected in the passenger seat, the state setting module 3 is triggered to enable the airbag.

[0102] The co-pilot detection module is used to detect whether there is a child seat on the co-pilot seat, and the corresponding detection results include whether there is a child seat or not.

[0103] The vehicle domain control unit 1 or the airbag control module 4 sets the state of the passenger airbag in combination with the detection result and the state setting signal. If there is a child seat on the passenger seat, and the state setting signal indicates that the state of the passenger airbag is set to disabled, the passenger airbag is correspondingly set to disabled. If there is a child seat on the passenger seat, and the state setting signal indicates that the state of the passenger airbag is set to enabled, the state setting signal is not responded to, and the passenger airbag remains disabled. On the contrary, if there is no child seat on the passenger seat, and the state setting signal indicates that the state of the passenger airbag is set to disabled, the state setting signal is not responded to, and the passenger airbag remains enabled to protect the safety of the passengers; if there is no child seat on the passenger seat, and the state setting signal indicates that the state of the passenger airbag is set to enabled, the passenger airbag is correspondingly set to enabled. The safety of the passenger airbag state setting is improved.

[0104] Optionally, the setting device further includes a memory 41 , and the memory 41 is connected to the airbag control module 4 .

[0105] It is understandable that the state data of the airbag is stored in the memory 41 , and when the state setting module 3 of the airbag is triggered, the state of the airbag is set based on the state successfully set by the user last time.

[0106] Based on the above embodiments, the present application also proposes a vehicle, which includes a cockpit, a passenger seat arranged in the cockpit, a passenger seat airbag and the passenger airbag status setting device as described above. The specific structure of the passenger airbag status setting device refers to the above embodiments.

[0107] The passenger airbag is arranged in front of the passenger seat;

[0108] The state setting device is connected to the passenger airbag and is configured to set the state of the passenger airbag;

[0109] The touch screen display 2 of the state setting device is disposed in the cockpit and is configured to set the state of the passenger airbag through the touch screen display 2 .

[0110] Optionally, the co-pilot detection module of the state setting device is installed on the co-pilot seat, and is used to detect the child seat on the co-pilot seat.

[0111] When the user needs to modify the status (on / off) of the airbag in the passenger seat, the user can touch the area of ​​the touch screen 2 corresponding to the status setting module 3 to trigger the status setting module 3. After receiving the operation instruction of the touch screen 2, the status setting module 3 sends the corresponding status modification signal to the vehicle domain control unit 1. The vehicle domain control unit 1 sends the corresponding status modification signal to the airbag control module 4. After receiving the status modification signal, the airbag control module 4 modifies the status of the airbag. At the same time, the airbag control module 4 feeds back the status information of the airbag to the vehicle domain control unit 1. The vehicle domain control unit 1 sends the prompt information corresponding to the status information to the prompt module 5. The prompt module 5 displays the prompt information on the touch screen 2 or on the instrument 6.

[0112] It can be understood that, in this embodiment, regardless of whether the state of the airbag is modified successfully, the touch screen display 2 will display the current state of the airbag so that the user can understand the current state of the airbag.

[0113] Furthermore, in this embodiment, even if the user does not issue an operation instruction, the vehicle domain control unit 1 receives feedback information from the airbag control module 4 in real time. Once the feedback status information of the airbag control module 4 changes and is not modified by the user, a prompt message is still issued to improve functional safety.

[0114] Since the state setting device in the vehicle of this embodiment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here. Among them, the passenger airbag state setting device is arranged on the vehicle body.

[0115] It can be understood that by providing the passenger airbag state setting device, it is convenient for the user to control the opening or disabling of the passenger airbag through the touch display screen 2.

[0116] Optionally, in embodiments of the present application, after the passenger airbag status setting function button is integrated into the touchscreen display, safety performance can be enhanced by configuring verification in the electronic system structure. Alternatively, program control can be combined to allow the passenger airbag status setting function button to be integrated into the touchscreen display without sacrificing safety properties. Optionally, in addition to the passenger airbag status setting function button, status setting buttons for other functional components with safety properties can also be integrated into the display screen using the implementation methods of embodiments of the present application. In other words, the integration of buttons for such functional components with safety properties into the touchscreen display is also within the scope of protection of embodiments of the present application.

[0117] The following examples illustrate the process of integrating the state setting button of a functional component with security attributes into a touch screen display and combining it with program control:

[0118] First embodiment

[0119] As shown in FIG2 , in this embodiment, the state setting method of the functional component includes:

[0120] Step S210: When receiving the state setting signal of the functional component, generating a setting verification channel and detecting the setting verification channel in real time;

[0121] This embodiment is described using the aforementioned passenger airbag state setting device as an example (hereinafter, the functional component is described as a passenger airbag). The state setting device is used to control the state setting of the passenger airbag. The state setting device includes a touch screen display, a state setting module, a vehicle domain control unit, and an airbag control module. The touch screen display is used to trigger the state setting module to generate a state setting signal, and the vehicle domain control unit is used to control the airbag control module to set the state of the passenger airbag.

[0122] The execution subject of this embodiment can be a state setting device or a vehicle domain control unit in the state setting device. The following description takes the execution subject as a vehicle domain control unit and the execution end as an airbag control module as an example.

[0123] When a user touches the display screen to trigger the state setting module to generate a state setting signal, the state setting signal is received. This triggers the generation of a verification channel. In this embodiment, the verification channel includes an input window and the verification transmission channel. The verification signal triggered by the verification input window is transmitted to the execution end via the verification transmission channel.

[0124] In this embodiment, after the state setting module generates a state setting signal, it triggers a verification process for the state setting signal to verify whether the triggered state setting signal is the setting signal expected by the user. The verification process includes: displaying the verification input window on the vehicle's touch screen display; the user can enter a confirmation instruction through the verification input window, which generates a corresponding verification signal, and the verification signal is transmitted to the execution end via the verification transmission channel.

[0125] In this embodiment, the verification transmission channel includes a first verification transmission channel between the setting verification module on the touch screen and the vehicle-domain control unit, and a second verification transmission channel between the vehicle-domain control unit and the airbag control module. The verification signal is transmitted from the touch screen to the vehicle-domain control unit, and then from the vehicle-domain control unit to the airbag control module.

[0126] In this embodiment, upon receiving a state setting signal from a functional component, the signal of the verification transmission channel is detected in real time. If the verification signal is detected on the verification transmission channel, it is determined that the user has entered a confirmation command in the verification input window. If no verification signal is detected, it is determined that the user has not entered a confirmation command in the verification input window, indicating that the state setting signal was falsely triggered. The state setting signal is then not responded to.

[0127] Step S220: If the verification signal of the setting verification channel is detected within the first preset time period, respond to the state setting signal;

[0128] Step S230: If the verification signal of the setting verification channel is not detected within the first preset time period, the state setting signal is not responded to, and a prompt message indicating that the state setting has failed is output.

[0129] In this embodiment, to further enhance the safety of the passenger airbag state setting, a validation signal validity period is set. For example, the validity period is a first preset duration, which defines the time interval between the state setting signal and the validation signal passing through the preset validation channel. When the time interval is less than or equal to the first preset duration, the state setting signal is considered valid, and a response to the state setting signal is issued.

[0130] Optionally, the verification signal is transmitted to the vehicle domain control unit via a first verification transmission channel, and then transmitted to the airbag control module via a second verification transmission channel.

[0131] This embodiment can verify the state setting signal when the verification signal is detected on the first verification transmission channel. For example, after the verification input window is displayed on the touch screen, the user needs to enter a confirmation instruction for verification within the first preset time length. Only the confirmation instruction entered within the first preset time length can be successfully verified and then respond to the state setting signal. If the confirmation instruction is not entered within the first preset time length, the verification is unsuccessful and the state setting signal is not responded. The time interval between the state setting signal and the verification signal passing through the first verification transmission channel is less than or equal to the first preset time length and is valid (that is, if the verification signal of the setting verification channel is detected within the first preset time length, the state setting signal is responded to).

[0132] This embodiment can also verify the state setting signal when a verification signal is detected in the second verification transmission channel. For example, when the vehicle domain control unit receives the state setting signal transmitted by the state setting module, it transmits the state setting signal to the airbag control module; when the vehicle domain control unit receives the verification signal transmitted by the state setting module, it also transmits the verification signal to the airbag control module. The airbag control module determines the validity of the state setting signal by verifying the time interval between the state setting signal and the verification signal passing through the second verification channel. The specific verification method is the same as the above method, both within the second preset time length, and the second preset time length can be equal to the first preset time length.

[0133] Based on this, when the state setting device is used as the execution body, step S220 includes verifying the verification signal of the first verification transmission channel between the touch display screen and the vehicle domain control unit, and verifying the verification signal of the second verification transmission channel between the vehicle domain control unit and the airbag control module. After both verifications are successful, respond to the state setting signal.

[0134] In this embodiment, the state setting module is integrated into the touch display screen, and when the state setting module generates a state setting signal, the verification of the state setting signal is triggered. After the vehicle domain control unit and the airbag control module successfully verify the state setting signal based on the verification signal, they respond to the state setting signal. In this way, the state setting physical button is cancelled and integrated into the touch display screen, thereby ensuring the safety attributes of the state setting module on the touch display screen and preventing the airbag control module from responding to erroneous triggering instructions.

[0135] Second embodiment

[0136] This embodiment is based on the first embodiment. In this embodiment, as shown in FIG3 , the method for setting the state of the functional component further includes:

[0137] Step S240: upon receiving a setting completion signal fed back in response to the state setting signal, outputting a prompt message corresponding to the setting completion signal to the touch screen display of the vehicle;

[0138] And / or, step S250: controlling the indicator indicating the status of the functional component on the vehicle instrument to display a prompt of the corresponding status according to the setting completion signal.

[0139] Take the passenger airbag as an example:

[0140] In this embodiment, after the airbag control module sets the status of the passenger airbag, it will feedback a setting completion signal to the vehicle domain control unit, and the airbag control module will feedback the setting completion signal to the touch screen and / or vehicle instrument, and prompt the setting information on the touch screen and / or vehicle instrument.

[0141] In a preferred embodiment, the prompt information is transmitted to the touch screen and to the vehicle instrument. The setting completion information is transmitted through two links, and prompts are given in two ways, making it easier for the user to know the setting status of the passenger airbag in a timely manner.

[0142] Optionally, the prompt information output by the touch screen includes a current status indicator of the passenger airbag and / or a safety instruction for the passenger, etc. The output mode of the prompt information includes at least one of text, picture, video and voice.

[0143] Optionally, the prompt information output by the instrument includes identification information of the status, and can be provided by flashing, lighting, etc.

[0144] Optionally, in some embodiments, the time limit from receiving the verification signal to receiving the feedback setting completion signal is set based on the speed at which the airbag control module responds to the status setting signal and the duration of the normal feedback setting completion signal. If the time limit is exceeded, the status setting signal may not be what the user expected, and a corresponding prompt message is output to prompt the user, so that the user can discover it in time.

[0145] Specifically, the state setting method of the functional component further includes:

[0146] When the verification signal is received, the timing of the third preset time period is started. When a setting completion signal fed back based on the response to the status setting signal is received within the third preset time period, the step of outputting the prompt information corresponding to the setting completion signal to the vehicle's touch screen display is executed, and / or the step of controlling the indicator indicating the status of the functional component on the vehicle instrument to display a prompt of the corresponding status according to the setting completion signal is executed.

[0147] If the third preset time period is exceeded, the display status setting signal is a prompt message not expected by the user.

[0148] For example, if the user intended the state setting, the user would promptly confirm the setting when the verification window appears on the touchscreen. This would shorten the time interval between the state setting signal and the verification signal, allowing the corresponding prompt to be quickly displayed on the touchscreen or instrument panel. Therefore, if the time interval between the verification signal and the feedback signal indicating the completion of the setting is within the third preset duration, the setting is determined to be the user's intended state setting. Conversely, if the vehicle domain control unit or airbag control module requires a longer time for verification and confirmation, the time interval between the verification signal and the feedback signal indicating the completion of the setting is longer, exceeding the third preset duration, and the setting is determined to be an unexpected state setting.

[0149] This embodiment sets the timeliness between signals to ensure that the status setting information is the modification currently expected by the user, and displays prompt information accordingly to prompt the user whether the modification result is consistent with the expectation. If it is not the modification currently expected by the user, a corresponding unexpected modification prompt information is displayed to facilitate the user to make timely corrections.

[0150] Third embodiment

[0151] This embodiment is based on all the above embodiments. When the functional component is a passenger airbag, the control is also combined with the seat signal on the passenger seat. As shown in Figure 4, the step of responding to the state setting signal includes:

[0152] Step S221, detecting a child seat signal on the passenger seat;

[0153] Step S222: setting the state of the passenger airbag according to the detection result and the state setting signal.

[0154] It should be noted that when a child seat is installed on the passenger seat, the airbag needs to be disabled to avoid injury to the child in the child seat when the airbag is opened. The airbag needs to be enabled in other usage scenarios to protect the safety of the occupants.

[0155] In order to avoid the situation where there is no child safety seat on the passenger seat and the user mistakenly sets the airbag to be disabled, or there is a child seat on the passenger seat and the user sets the airbag to be enabled, this embodiment combines the detection of the child seat on the passenger seat, and sets the status of the passenger airbag through the combination of the detection result and the status setting signal, thereby further improving the safety attributes of the touch display screen status setting.

[0156] Optionally, the step of setting the state of the passenger airbag according to the detection result and the state setting signal includes but is not limited to the following process:

[0157] If the detection result is that a child seat signal is detected and the state setting signal is a disable signal, the passenger airbag is set to a disable state;

[0158] If the detection result is that no child seat signal is detected and the state setting signal is a disable signal, the passenger airbag is kept in the enabled state and a disable setting failure prompt message is output.

[0159] If the detection result is that a child seat signal is detected and the status signal is an activation signal, the passenger airbag is kept in a disabled state and an activation setting failure prompt message is output;

[0160] If the detection result is that no child seat signal is detected and the status signal is an activation signal, the passenger airbag is set to an activation state.

[0161] This embodiment can make the state setting of the passenger airbag consistent with the safe use state of the passenger seat, avoiding dangerous human operation.

[0162] Alternatively, in some embodiments, the passenger detection module is connected to the vehicle domain control unit, and the vehicle domain control unit triggers the state setting module to automatically generate a state setting signal, thereby automatically triggering a state setting. For example, if a child seat is detected in the passenger seat, the state setting module is triggered to disable the airbag. If no child seat is detected in the passenger seat, the state setting module is triggered to enable the airbag.

[0163] In this embodiment, the method further includes:

[0164] Detect whether there is a child seat signal on the passenger seat;

[0165] If so, determining whether the current state of the vehicle's passenger airbag is enabled;

[0166] If yes, a state setting signal indicating disable is generated, and then step S210 is executed;

[0167] If disabled, the current state is maintained.

[0168] On the contrary, if there is no child seat signal and the current state is enabled, the current state is maintained;

[0169] If the current state is disabled, a state setting signal indicating enabled is generated, and then step S210 is executed.

[0170] In this way, the passenger airbag status can be automatically switched based on the status of the child seat in the passenger seat. Although automation is more in line with intelligent development, manual triggering by the user is more in line with user expectations.

[0171] Optionally, an embodiment of the present application also provides a vehicle, comprising: a memory, a processor, and a state setting program stored in the memory and executable on the processor, wherein the state setting program, when executed by the processor, implements various embodiments of the state setting method of the functional components described above.

[0172] The above description is merely an optional embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made based on the inventive concept of the present application using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
