Description

Technical Field

[0001] This invention relates to the field of vehicle equipment technology, and in particular to a method for setting the status of a functional component, a passenger airbag status setting device, and a vehicle. Background Technology

[0002] For vehicles equipped with a front passenger airbag, the airbag's disabled and deployed status is crucial to user safety. If a child is in the front passenger seat, the airbag must be disabled; otherwise, deployment during a collision could be fatal to the child. Conversely, if an adult, not a child, is in the front passenger seat, the airbag must deploy to protect the adult during a collision. Therefore, the airbag's status setting and indication have functional safety attributes, and thus, safety requirements are typically placed on the control switch and status display.

[0003] Because physical buttons have certain safety attributes, most related technologies use physical buttons to control the status of the passenger airbag. However, physical buttons with safety attributes are expensive. Summary of the Invention

[0004] The main objective of this invention is to propose a method for setting the state of functional components, a passenger-side airbag state setting device, and a vehicle, aiming to eliminate physical buttons and integrate them into the display screen for control, while ensuring that the control functions integrated into the display screen have safety attributes.

[0005] To achieve the above objectives, the present invention proposes a method for setting the state of a functional component, the method comprising:

[0006] Upon receiving a status setting signal from a functional component, a setting verification channel is generated, and the setting verification channel is monitored in real time.

[0007] If a verification signal of the set verification channel is detected within the first preset time period, then the status setting signal is responded to;

[0008] If no verification signal of the set verification channel is detected within the first preset time period, the status setting signal will not be responded to, and a status setting failure prompt message will be output.

[0009] Optionally, the setting verification channel includes a verification input window and the verification transmission channel, and the verification signal triggered by the verification input window is transmitted to the execution end through the verification transmission channel;

[0010] When the status setting of a functional component is received, the verification input window is displayed on the vehicle's touch screen.

[0012] Optionally, the method for setting the state of the functional component further includes:

[0013] Upon receiving a setting completion signal based on the response to the state setting signal, the system outputs a prompt message corresponding to the setting completion signal to the vehicle's touch screen display.

[0014] And / or, according to the set completion signal control, the indicator on the vehicle instrument panel that indicates the status of the passenger-side airbag will display a corresponding status prompt.

[0015] Optionally, the method for setting the state of a functional component further includes:

[0016] Upon receiving the verification signal, a third preset time period is started. Within the third preset time period, when a setting completion signal is received based on the response to the state setting signal, the step of outputting the prompt information corresponding to the setting completion signal to the vehicle's touch screen is executed, and / or, according to the setting completion signal, the step of controlling the indicator on the vehicle's instrument panel indicating the status of the passenger-side airbag to display the corresponding status prompt is executed.

[0017] Optionally, the step of responding to the state setting signal includes:

[0019] Based on the test results and the status setting signal, the status of the passenger airbag is set.

[0020] Optionally, the step of setting the state of the passenger-side airbag based on the detection result and the state setting signal includes:

[0021] If the detection result indicates that a child seat signal has been detected, and the status setting signal is a disabled signal, then the passenger airbag is set to a disabled state.

[0022] If the detection result is that no child seat signal is detected, and the status setting signal is a disabled signal, the active state of the passenger airbag is maintained, and a disabled setting failure prompt message is output.

[0023] If the detection result indicates that a child seat signal has been detected, and the status signal is an enabled signal, then the passenger airbag remains disabled, and an enable setting failure message is output.

[0024] If the detection result indicates that no child seat signal is detected, and the status signal is an enabled signal, then the passenger airbag is set to enabled.

[0025] The present invention also provides a passenger-side airbag status setting device, including a touch screen, a status setting module, a vehicle domain control unit, and an airbag control module;

[0026] The status setting module is used to set the status of the passenger-side airbag. The status setting module generates a status setting signal and a verification signal through the touch operation of the touch screen, and transmits the status setting signal and the verification signal to the vehicle domain control unit.

[0027] The vehicle domain control unit is configured to send the status setting signal to the airbag control module when it receives the status setting signal; and to send the verification signal to the airbag control module when it receives the verification signal within a first preset time period.

[0028] An airbag control module is connected to the vehicle domain control unit and the passenger airbag respectively. The airbag control module is configured to receive the status setting signal, and when it receives the verification signal within a second preset time period, it sets the status of the passenger airbag according to the status setting signal.

[0029] Optionally, the status setting module includes:

[0030] A status setting control generates a status setting signal through touch operation of the touch screen and transmits the status setting signal to the vehicle domain control unit;

[0031] A verification control is configured to be displayed on the touch screen when the status setting control generates the status setting signal, and to transmit the verification signal to the vehicle domain control unit when a verification signal is generated by touch operation on the touch screen within the first preset time period.

[0032] Optionally, the vehicle domain control unit includes: a battery status management module and a processing module, wherein the battery status management module is connected to the status setting module, and the processing module is connected to the battery management status and the airbag control module respectively;

[0033] The battery status management module is configured to send the status setting signal to the processing module when it receives the status setting signal; and to send the verification signal to the processing module when it receives the verification signal within a first preset time period.

[0034] The processing module is configured to send the status setting signal to the airbag control module when it receives the status setting signal; and to send the verification signal to the airbag control module when it receives the verification signal within a first preset time period.

[0035] Optionally, it also includes a prompting module, which is connected to the vehicle domain control unit;

[0036] The airbag control module is also configured to send a setting completion signal to the vehicle domain control unit after successfully setting the status of the passenger airbag.

[0037] The vehicle domain control unit is also configured to output a setting completion prompt command after receiving the setting completion signal;

[0040] The vehicle domain control unit is also configured to output an expected setting completion prompt instruction when the setting completion signal is received within the third preset time period; and to output an unexpected setting completion prompt instruction when the setting completion signal is received after the third preset time period has ended.

[0041] Optionally, the prompt module is located on the touch display screen, and / or the prompt module is located on the vehicle's instrument panel.

[0042] Optionally, it also includes a passenger seat detection module, which is connected to the vehicle domain control unit or the airbag control module, and is configured to send the detection results of the child seat in the passenger seat to the vehicle domain control unit or the airbag control module.

[0047] Optionally, the co-driver detection module of the status setting device is installed in the co-driver's seat to detect the child seat in the co-driver's seat.

[0048] In this invention, the status setting module is integrated into the touch screen. When the status setting module generates a status setting signal, it triggers the verification of the status setting signal. After the vehicle domain control unit and the airbag control module successfully verify the status setting signal based on the verification signal, the status setting signal is then responded to. In this way, the physical status setting button is eliminated, and by integrating it into the touch screen, the safety attributes of the status setting module on the touch screen are ensured, and the airbag control module is prevented from responding to erroneous trigger commands, thereby improving functional safety.

[0056] The implementation, features, and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0058] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure).

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0060] With the trend towards intelligent technology, many physical buttons have been integrated into displays for aesthetic purposes. However, touchscreens are prone to accidental touches, leading to lower security. For physical buttons with lower security requirements, their functionality has been eliminated, integrating them into the display, thus sacrificing their original function. However, the activation and deactivation settings for vehicle airbags cannot ignore their safety function; therefore, the industry can only use physical buttons for control, as integrating them into the display is not feasible.

[0061] The present invention addresses the above-mentioned problems by proposing a passenger airbag status setting device, which eliminates physical buttons and integrates them into the display screen for control, while ensuring the safety of airbag status setting.

[0062] Specifically, please refer to Figure 1The passenger-side airbag status setting device includes a touch screen display 2, a status setting module 3, a vehicle domain control unit 1, and an airbag control module 4. Optionally, the touch screen display 2 is a display screen in the vehicle's cockpit, and the touch screen display 2 has touch functionality, allowing users to input control commands / information through the touch screen display 2. Alternatively, the touch screen display 2 also has voice acquisition functionality, allowing users to input control voice commands through the touch screen display 2.

[0063] Optionally, the status setting module 3 is used to set the status of the passenger-side airbag. The status of the passenger-side airbag includes an activated state and a disabled state. When the airbag is in the activated state, it will deploy in the event of a collision to protect the passenger-side occupant; when the airbag is in the disabled state, it will not deploy in the event of a collision and will remain in an unused state.

[0064] In this embodiment, the setting switch for the passenger-side airbag is integrated into the touchscreen display 2, allowing the setting of the passenger-side airbag status to be triggered via the touchscreen display 2. Optionally, the physical switch can be configured as the status setting module 3, integrated into the touchscreen display 2. In this case, the status setting module 3 generates a status setting signal through touch operations on the touchscreen display 2, and the status of the passenger-side airbag is set via the status setting signal. Optionally, the touchscreen display 2 is a large screen in the vehicle's cockpit, allowing either the driver or passenger to control the system via the touchscreen display 2.

[0065] In this embodiment, to improve the touch security of the touch display 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 the touch operation of the touch display screen 2, the state setting module 3 displays a verification window on the touch display screen 2 for user touch. The state setting module 3 also generates a verification signal through the touch operation of the touch display screen 2 and transmits the verification signal to the vehicle domain control unit 1 to verify whether the state setting signal is genuine and valid or accidentally triggered. Optionally, in this embodiment, the validity period of the verification window on the touch display 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 can no longer trigger the verification window. In this way, the state setting module 3 will not generate a verification signal. If the state setting signal is accidentally triggered by the user, the probability of triggering the verification window again within the first preset duration is extremely low, thereby achieving safety control against accidental triggering. Optionally, in other embodiments, the verification window of the touch screen 2 can be set to remain valid until the current setting ends (i.e., the valid time is greater than the first preset duration). The user can trigger the verification window at any time. When the verification window is triggered, the status setting module 3 generates verification information and transmits it to the vehicle domain control unit 1. In this case, the vehicle domain control unit 1 can be used to verify whether the status setting signal is falsely triggered.

[0066] Optionally, the vehicle domain control unit 1 is configured to receive the status setting signal, and when the verification signal is received within a first preset time period, determine that the status setting signal has been successfully verified.

[0067] Optionally, the processing procedure of the vehicle domain control unit 1 for the signal transmitted by the status setting module 3 is as follows: When the vehicle domain control unit 1 receives the status setting signal, it sends the status setting signal to the airbag control module 4 and starts timing (either forward or countdown). If a verification signal is received within a 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 status setting channel is closed, and the airbag status cannot be set. This avoids the user accidentally triggering the status setting signal and causing incorrect airbag status settings, thus improving the safety of airbag status setting.

[0068] Optionally, an airbag control module 4 is connected to the vehicle domain control unit 1 and the passenger airbag respectively. The airbag control module 4 is configured to receive the status setting signal, and when it receives the verification signal within a second preset time period, it sets the status of the passenger airbag according to the status setting signal.

[0069] The airbag control module 4 is used to control the state of the airbag, such as controlling the airbag to be in an enabled state or in a disabled state. Optionally, in some embodiments, when the airbag control module 4 receives the state setting signal, it also needs to verify the authenticity of the state setting signal through a verification signal to further improve the setting control of the airbag state. Specifically, the airbag control module 4 determines this by verifying whether the time interval between receiving the state setting signal and the verification signal meets a second preset duration. Thus, even if the verification by the vehicle domain control unit 1 is incorrect, the airbag control module 4 can re-verify the authenticity of the state setting signal, further improving the safety of the airbag state setting.

[0070] Optionally, the first preset duration and the second preset duration are configured to be the same under normal circumstances. However, under special circumstances, the first preset duration and the second preset duration can be configured to be different according to requirements.

[0071] Optionally, the first preset duration can be timed based on the timing module 13 of the vehicle domain control unit 1 itself (which may or may not share the same timing module as the third preset duration described below), or it can be timed through an external timing module. Similarly, the second preset duration can be timed based on the timing module of the airbag control module 4 itself, or it can be timed through an external timing module. Optionally, the timing module communicates with the touch display screen 2 to display the timing process of the timing module on the screen.

[0072] Alternatively, in some other embodiments, the airbag control module 4 may not need to be verified; upon receiving the status setting signal, it may directly set the status of the passenger-side airbag.

[0073] Setting the passenger-side airbag status is also a way to modify its status. For example, setting the passenger-side airbag status to disabled will change the passenger-side airbag status from enabled to disabled; setting the passenger-side airbag status to enabled will change the passenger-side airbag status from disabled to enabled.

[0074] Optionally, in some embodiments, the status of the passenger-side airbag can be set by modifying the control switch of the passenger-side airbag, or by modifying the passenger-side airbag control program.

[0075] In this embodiment, the status setting module 3 is integrated into the touch screen 2. When the status setting module 3 generates a status setting signal, the verification of the status setting signal is triggered. After the vehicle domain control unit 1 and the airbag control module 4 successfully verify the status setting signal based on the verification signal, the status setting signal is responded to. In this way, the physical status setting button is eliminated and integrated into the touch screen 2, ensuring the safety attributes of the status setting module 3 on the touch screen 2 and preventing the airbag control module 4 from responding to false trigger commands.

[0076] In some optional embodiments, the status setting module 3 includes a status setting control 31 and a setting verification control 32.

[0077] The status setting control 31 is displayed on the touch screen 2. The user can trigger the status setting control 31 through the touch 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. After generating the status setting signal, the status setting control 31 transmits the status setting signal to the vehicle domain control unit 1 so that the vehicle domain control unit 1 can execute the status setting signal.

[0078] The setting verification control 32 is communicatively connected to the state setting control 31. When the state setting control 31 generates a state setting signal, it triggers the setting verification control 32, causing the setting verification control 32 to be displayed on the touch screen 2.

[0079] In this embodiment, when the setting verification control 32 is triggered, it is displayed on the touch screen 2 (e.g., displaying an input window for the setting verification control 32 on the screen, or displaying an identifier for the setting verification control 32, such as text, icon, video, or audio). When the setting verification control 32 is displayed on the touch screen 2, the user can trigger the setting verification control 32 through the touch screen 2, and the setting verification control 32 will generate 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.

[0080] In this embodiment, in order to improve the safety of the passenger airbag setting, the validity period of the verification signal generated by the setting verification control 32 is configured. For example, if the user triggers the setting verification control 32 within a first preset time after triggering the state setting control 31, the generation time interval between the state setting signal and the verification signal is less than or equal to the first preset time. In this way, under normal communication between the state setting module 3 and the vehicle domain control unit 1, after the vehicle domain control unit 1 receives the state setting signal, it will receive the verification signal within the first preset time. Thus, the vehicle domain control unit 1 can determine that the state setting signal is the setting expected by the user.

[0081] This embodiment uses a status setting control 31 and a setting verification control 32 to manually confirm the status again after setting it, and then the system sets the passenger airbag status, which improves the safety of the passenger airbag status setting and makes up for the safety defects of the touch screen.

[0082] In some optional embodiments, the vehicle domain control unit 1 includes: a battery status management module 11 and a processing module 12, wherein 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;

[0083] The battery status management module 11 is configured to send the status setting signal to the processing module 12 when it receives the status setting signal; and to send the verification signal to the processing module 12 when it receives the verification signal within a first preset time period.

[0084] The processing module 12 is configured to send the status setting signal to the airbag control module 4 when it receives the status setting signal; and to send the verification signal to the airbag control module 4 when it receives the verification signal within a first preset time period.

[0085] Optionally, the processing module 12 is equivalent to a central processing unit.

[0086] When this embodiment is applied in the field of electric vehicles, the airbags can be controlled based on the battery status management module 11 in combination with the vehicle's usage, thereby improving the safety of the airbag status settings.

[0087] In an optional embodiment, the passenger airbag status setting device further includes a prompting module 5, which is connected to the vehicle domain control unit 1;

[0088] The airbag control module 4 is also configured to send a setting completion signal to the vehicle domain control unit 1 after successfully setting the status of the passenger airbag.

[0089] The vehicle domain control unit 1 is also configured to output a setting completion prompt command after receiving the setting completion signal;

[0090] The prompting module 5 is configured to output prompt information corresponding to the setting completion prompting command when it receives the setting completion prompting command fed back by the vehicle domain control unit 1.

[0091] In this embodiment, after the airbag control module 4 sets the status of the passenger-side airbag, it sends a setting completion signal and prompts the user through the prompt module 5 to indicate the current status of the passenger-side airbag. If the current status is not what the user expects, the user can promptly modify the status of the passenger-side airbag based on the prompt; if the current status is what the user expects, the prompt message confirms to the user that the passenger-side airbag status meets their expectations and that safe driving is possible.

[0092] Optionally, in this embodiment, the prompting module 5 can display a message indicating that the setting is complete, or a message indicating that the setting was unsuccessful. For example, if the airbag control module 4 has not set the passenger-side airbag, it will also send a signal indicating that the setting is not complete, and then the vehicle domain control unit 1 will output a message indicating that the setting is not complete, at which point the prompting module 5 will display the corresponding message.

[0093] Optionally, in this embodiment, the prompting module 5 is disposed on the touch display screen 2, and / or the prompting module 5 is disposed on the vehicle's instrument panel 6.

[0094] In a preferred embodiment, the prompt module 5 is provided on both the touch screen 2 and the vehicle's instrument panel 6, and the two prompt modules 5 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-side airbag setting status, improving the setting effect of the touch screen 2 and enhancing the user experience.

[0095] In an optional embodiment, the device further includes a timing module 13, which is connected to the vehicle domain control unit 1. The timing module 13 is configured to start timing for a third preset duration based on the vehicle domain control unit 1 receiving the verification signal within a first preset duration.

[0096] 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 to output an unexpected setting completion prompt instruction when the setting completion signal is received after the third preset time period has ended.

[0097] In this embodiment, based on the response speed of the airbag control module 4 to the status setting signal and the duration of the normal feedback setting completion signal, a time limit is set from receiving the verification signal to receiving the feedback setting completion signal. If this time limit is exceeded, the status setting signal may not be what the user expected, and a corresponding prompt message is output to alert the user, allowing the user to detect it promptly. Based on this, in this embodiment, the vehicle domain control unit 1 determines whether the status setting signal is an expected modification based on the time interval between receiving the setting completion signal and receiving the verification signal. If not, the user is reminded that the modification is unexpected; if so, the user is prompted that the system has completed the modification as expected. This improves the security of status setting.

[0098] Optionally, in some embodiments, to further improve the safety of the front passenger airbag status setting and avoid mismatches between the set status and the safety protection of the front passenger occupant (e.g., the user sets it to disabled but the front passenger is an adult, or the user sets it to enabled but the front passenger is in a child seat), the device proposed in this embodiment further includes a front passenger detection module. This front passenger detection module is connected to the vehicle domain control unit 1 or the airbag control module 4, and is configured to send the detection results of the child seat in the front passenger seat to the vehicle domain control unit 1 or the airbag control module 4.

[0099] 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, when a child seat is detected in the passenger seat, the state setting module 3 is triggered to set the airbag to disabled. When no child seat is detected in the passenger seat, the state setting module 3 is triggered to set the airbag to enabled.

[0100] The passenger seat detection module is used to detect whether there is a child seat in the passenger seat, and the corresponding detection results include whether there is a child seat or not.

[0101] The vehicle domain control unit 1 or airbag control module 4, in conjunction with the detection results and status setting signals, sets the status of the passenger-side airbag. If a child seat is present in the passenger seat and the status setting signal indicates that the passenger-side airbag is disabled, then the passenger-side airbag is disabled accordingly. If a child seat is present in the passenger seat and the status setting signal indicates that the passenger-side airbag is enabled, then the status setting signal is not responded to, and the passenger-side airbag remains disabled. Conversely, if there is no child seat in the passenger seat and the status setting signal indicates that the passenger-side airbag is disabled, then the status setting signal is not responded to, and the passenger-side airbag remains enabled to protect the safety of the occupants; if there is no child seat in the passenger seat and the status setting signal indicates that the passenger-side airbag is enabled, then the passenger-side airbag is enabled accordingly. This improves the safety of the passenger-side airbag status setting.

[0102] Optionally, the setting device further includes a memory 41, which is connected to the airbag control module 4.

[0103] It is understandable that by storing the airbag status data in the memory 41, when the airbag status setting module 3 is triggered, the airbag status is set based on the last successful user setting status.

[0104] Based on the above embodiments, the present invention also proposes a vehicle, the vehicle including a driver's cabin, a passenger seat disposed in the driver's cabin, a passenger seat airbag, and a passenger seat airbag status setting device as described above, the specific structure of which refers to the above embodiments.

[0105] The passenger-side airbag is located in front of the passenger seat;

[0106] The status setting device is connected to the passenger airbag and is configured to set the status of the passenger airbag.

[0107] The touch screen 2 of the status setting device is located in the cockpit and is configured to set the status of the passenger airbag via the touch screen 2.

[0108] Optionally, the co-driver detection module of the status setting device is installed in the co-driver's seat to detect the child seat in the co-driver's seat.

[0109] When a user needs to modify the status (deployed / disabled) of the passenger-side airbag, they can touch the corresponding area of ​​the status setting module 3 on the touchscreen display 2 to trigger the status setting module 3. Upon receiving the operation command from the touchscreen display 2, the status setting module 3 sends a corresponding status modification signal to the vehicle domain control unit 1. The vehicle domain control unit 1 then sends the corresponding status modification signal to the airbag control module 4. Upon receiving the status modification signal, the airbag control module 4 modifies the airbag status setting. Simultaneously, the airbag control module 4 feeds back the airbag status information to the vehicle domain control unit 1. The vehicle domain control unit 1 sends a corresponding prompt message to the prompt module 5, which displays the prompt message on the touchscreen display 2 or on the instrument panel 6.

[0110] It is understood that in this embodiment, regardless of whether the airbag status modification is successful, the touch screen 2 will display the current status of the airbag so that the user can understand the current status of the airbag.

[0111] Furthermore, in this embodiment, even if the user does not issue an operation command, the vehicle domain control unit 1 receives feedback information from the airbag control module 4 in real time. Once the status information fed back by the airbag control module 4 changes, and it is not modified by the user, a prompt message is still issued to improve functional safety.

[0112] Since the status 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 about by the technical solutions of the above embodiments, and will not be described in detail here. The passenger-side airbag status setting device is located on the vehicle body.

[0113] Understandably, by setting the passenger airbag status setting device, users can easily control the opening or disabling of the passenger airbag via the touch display screen 2.

[0114] Optionally, in this embodiment of the invention, after the passenger-side airbag status setting function button is integrated into the touch screen, safety performance can be improved by configuring and verifying it in the electronic system structure. Alternatively, it can be combined with program control so that the passenger-side airbag status setting function button is integrated into the touch screen without sacrificing its safety attributes. Optionally, in addition to the passenger-side airbag status setting function button, status setting buttons for other functional components with safety attributes can also be integrated into the display screen using the implementation method of this embodiment of the invention. That is, the integration of such buttons for functional components with safety attributes into the touch screen is also within the scope of protection of this embodiment of the invention.

[0115] The following examples illustrate the process of integrating status setting buttons for functional components with safety attributes into a touch screen and combining them with program control:

[0116] First Embodiment

[0117] like Figure 2 As shown, in this embodiment, the method for setting the state of the functional component includes:

[0118] Step S210: When a status setting signal of a functional component is received, a setting verification channel is generated, and the setting verification channel is monitored in real time.

[0119] This embodiment uses the aforementioned passenger-side airbag status setting device as an example for explanation (the following explanation also uses the passenger-side airbag as the functional component). This status setting device controls the status setting of the passenger-side airbag. The status setting device includes a touch screen, a status setting module, a vehicle domain control unit, and an airbag control module. The touch screen triggers the status setting module to generate a status setting signal, and the vehicle domain control unit controls the airbag control module to set the status of the passenger-side airbag.

[0120] In this embodiment, the executing entity can be a state setting device or a vehicle domain control unit within the state setting device. The following explanation uses the vehicle domain control unit as the executing entity and the airbag control module as the executing end.

[0121] When a user triggers the state setting module to generate a state setting signal via a touchscreen display, the user receives the state setting signal. At this time, a verification channel is generated. In this embodiment, the verification channel includes an input window and a verification transmission channel. The verification signal triggered by the verification input window is transmitted to the execution end through the verification transmission channel.

[0122] In this embodiment, after the state setting module generates a state setting signal, it triggers a verification procedure for the state setting signal to verify whether the triggered state setting signal is the setting signal expected by the user. The verification procedure is as follows: the verification input window is displayed on the vehicle's touch screen; the user can input a confirmation command through the verification input window, which will generate a corresponding verification signal, and the verification signal will be transmitted to the execution end through the verification transmission channel.

[0123] 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.

[0124] In this embodiment, upon receiving a status setting signal from a functional component, the signal of the verification transmission channel is monitored in real time. If the verification signal is detected in the verification transmission channel, it is determined that the user has entered a confirmation command from the verification input window. If no verification signal is detected, it is determined that the user has not entered a confirmation command from the verification input window, indicating that the status setting signal was falsely triggered. Therefore, the status setting signal is not responded to.

[0125] Step S220: If a verification signal of the set verification channel is detected within the first preset time period, then respond to the state setting signal;

[0126] Step S230: If no verification signal of the set verification channel is detected within the first preset time period, the status setting signal is not responded to, and a status setting failure prompt message is output.

[0127] In this embodiment, to further improve the safety attributes of the passenger-side airbag status setting, a valid time limit for the verification signal is set. For example, the valid time limit is a first preset duration. The first preset duration limits the time interval between the status setting signal and the verification signal passing through the set verification channel. When the time interval is less than or equal to the first preset duration, the status setting signal is valid, and a response to the status setting signal is initiated.

[0128] Optionally, the verification signal is transmitted to the vehicle domain control unit via the first verification transmission channel, and then to the airbag control module via the second verification transmission channel.

[0129] This embodiment can verify the status setting signal when a verification signal is detected in the first verification transmission channel. For example, after the verification input window is displayed on the touch screen, the user needs to input a confirmation command within a first preset time period to verify. Only if the confirmation command is input within the first preset time period will the verification be successful, and the status setting signal will be responded to. If no confirmation command is input within the first preset time period, the verification will fail, and the status setting signal will not be responded to. The time interval between the status setting signal and the verification signal passing through the first verification transmission channel is less than or equal to the first preset time period and is valid (that is, if the verification signal of the setting verification channel is detected within the first preset time period, the status setting signal will be responded to).

[0130] This embodiment can also verify the state setting signal when the 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 described above, both occurring within a second preset time period, which can be equal to the first preset time period.

[0131] Based on this, when the state setting device is used as the execution subject, step S220 includes verifying the verification signal of the first verification transmission channel between the touch 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 are successfully verified, the state setting signal is responded to.

[0132] In this embodiment, the status setting module is integrated into the touch screen. When the status setting module generates a status setting signal, the verification of the status setting signal is triggered. After the vehicle domain control unit and the airbag control module successfully verify the status setting signal based on the verification signal, the status setting signal is responded to. In this way, the physical status setting button is eliminated and integrated into the touch screen, ensuring the safety attributes of the status setting module on the touch screen and preventing the airbag control module from responding to false trigger commands.

[0133] Second Embodiment

[0134] This embodiment is based on the first embodiment described above. In this embodiment, as follows: Figure 3 As shown, the method for setting the state of the functional component further includes:

[0135] Step S240: Upon receiving a setting completion signal based on the response to the state setting signal, output a prompt message corresponding to the setting completion signal to the vehicle's touch screen display.

[0136] And / or, step S250: according to the set completion signal, control the display of the corresponding status prompt on the vehicle instrument panel to indicate the status of the functional components.

[0137] Taking the passenger-side airbag as an example:

[0138] In this embodiment, after the airbag control module sets the status of the passenger-side airbag, it sends a setting completion signal to the vehicle domain control unit. The airbag control module then sends the setting completion signal to the touch screen and / or the vehicle instrument panel, displaying the setting information on the touch screen and / or the vehicle instrument panel.

[0139] In a preferred embodiment, the prompt information is transmitted to the touch screen and to the vehicle instrument panel. The setting completion information is transmitted through two links, and the prompt is given in two ways, making it easier for the user to know the setting status of the passenger airbag in a timely manner.

[0140] Optionally, the prompts displayed on the touchscreen may include the current status of the passenger-side airbag and / or safety instructions for passenger use. The prompts may be displayed in at least one of the following formats: text, images, video, and voice.

[0141] Optionally, the instrument output may include status indicators. These can be indicated by flashing lights, illumination, or other means.

[0142] Optionally, in some embodiments, the time limit from receiving the verification signal to receiving the feedback setting completion signal is set according to the response status setting signal speed of the airbag control module 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 expects, and the corresponding prompt information is output to prompt the user so that the user can discover it in time.

[0143] Specifically, the method for setting the state of functional components also includes:

[0144] When the verification signal is received, a third preset time period is started. When a setting completion signal is received within the third preset time period based on the response to the state setting signal, the step of outputting the prompt information corresponding to the setting completion signal to the vehicle's touch screen is executed, and / or the step of controlling the indicator of the state of the functional component on the vehicle's instrument panel to display the prompt corresponding to the state is executed according to the setting completion signal.

[0145] If the third preset time is exceeded, the status setting signal will display an unexpected prompt message.

[0146] For example, if the user expects the desired state setting, they will promptly confirm the setting when the verification window appears on the touchscreen. In this case, the time interval between the state setting signal and the verification signal is short, and the corresponding prompt information can be quickly displayed on the touchscreen or instrument panel. Therefore, if the time interval between the verification signal and the feedback setting completion signal is within the third preset duration, it is determined to be the user's expected state setting. Conversely, if the vehicle domain control unit or airbag control module requires a longer verification and confirmation time, and the time interval between the verification signal and the feedback setting completion signal is longer than the third preset duration, it is determined to be an unexpected state setting.

[0147] This embodiment ensures that the status setting information is what the user currently expects to modify by setting the timeliness between signals. Corresponding prompts are displayed to indicate whether the modification result is consistent with the expectation. If it is not what the user currently expects to modify, corresponding prompts for unexpected modification are displayed to facilitate timely correction by the user.

[0148] Third Embodiment

[0149] This embodiment is based on all the above embodiments. When the functional component is the passenger-side airbag, it is also controlled in conjunction with the passenger-side seat signal. For example... Figure 4 As shown, the step of responding to the state setting signal includes:

[0150] Step S221: Detect the child seat signal in the front passenger seat;

[0151] Step S222: Based on the detection results and the status setting signal, set the status of the passenger airbag.

[0152] It should be noted that when a child seat is installed in the front passenger seat, the airbag should be disabled to avoid injury to the child in the airbag when it deploys. In other usage scenarios, the airbag should be enabled to protect the safety of the occupants.

[0153] To prevent situations where there is no child safety seat in the front passenger seat and the user mistakenly sets the airbag to disabled, or where there is a child safety seat in the front passenger seat and the user sets the airbag to enabled, this embodiment combines detection of the child safety seat in the front passenger seat with the detection results and status setting signals to set the status of the front passenger airbag, further improving the safety attributes of the touch screen status settings.

[0154] Optionally, the step of setting the state of the passenger-side airbag based on the detection results and the state setting signal includes, but is not limited to, the following processes:

[0155] If the detection result indicates that a child seat signal has been detected, and the status setting signal is a disabled signal, then the passenger airbag is set to a disabled state.

[0156] If the detection result indicates that no child seat signal is detected, and the status setting signal is a disabled signal, the active state of the passenger airbag is maintained, and a disabled setting failure prompt message is output.

[0157] If the detection result indicates that a child seat signal has been detected, and the status signal is an enabled signal, then the passenger airbag remains disabled, and an enable setting failure message is output.

[0158] If the detection result indicates that no child seat signal is detected, and the status signal is an enabled signal, then the passenger airbag is set to enabled.

[0159] This embodiment ensures that the status setting of the passenger-side airbag is consistent with the safe usage status of the passenger-side seat, avoiding dangerous human-caused operations.

[0160] Alternatively, in some embodiments, the passenger detection module is connected to the vehicle domain control unit, and the vehicle domain control unit triggers the status setting module to automatically generate a status setting signal, thereby automatically triggering the status setting. For example, when a child seat is detected in the passenger seat, the status setting module is triggered to set the airbag to disabled. When no child seat is detected in the passenger seat, the status setting module is triggered to set the airbag to enabled.

[0161] In this embodiment, the method further includes:

[0162] Check if there is a child seat signal in the front passenger seat;

[0163] If so, determine whether the current status of the vehicle's passenger airbag is enabled;

[0164] If so, a status setting signal indicating that the status is disabled is generated, and then step S210 is executed.

[0165] If disabled, the current state will be maintained.

[0166] Conversely, if there is no child seat signal and the current status is enabled, the current status will remain unchanged;

[0167] If the current state is disabled, a state setting signal indicating that it is enabled is generated, and then step S210 is executed.

[0168] In this way, the status of the passenger airbag can be automatically switched based on the status of the child seat in the front passenger seat. Although automation is more in line with the development of intelligent technology, manual activation by the user is more in line with user expectations.

[0169] Optionally, embodiments of the present invention also provide a vehicle, the 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 above-mentioned functional components.

[0170] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
