Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a method and device for unlocking a vehicle door handle. Background Technology

[0002] Currently, if a vehicle is involved in an accident, the door handles will automatically unlock, meaning the door can be opened using the door handles.

[0003] Since most car manufacturers use electronic control for door handles, which involves locking and unlocking the door handles via CAN or other forms of electrical signals, if the electronic control circuit is cut off during a vehicle accident, meaning the transmission line of the electrical signals is severed, the door handles cannot be unlocked, and the car door cannot be opened using the door handles. As a result, the user cannot open the car door in time, which may lead to the user being trapped inside the car, and in severe cases, may endanger the user's life.

[0004] Therefore, improving the reliability of vehicle door handle unlocking is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] In view of this, the present invention provides a door handle unlocking control method and a door handle unlocking device for a vehicle, so as to improve the unlocking reliability of the vehicle door handle.

[0006] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0007] The first aspect of this application provides a method for unlocking a vehicle door handle, including:

[0008] When the electronic control unit module in the vehicle is enabled, it is determined whether the electronic control unit module has malfunctioned, and / or whether the signal transmission of the electronic control unit module has malfunctioned; the electronic control unit module is a module that unlocks the door handle by sending an electrical signal to the door handle in the vehicle;

[0009] If the electronic control unit module malfunctions, and / or the signal transmission of the electronic control unit module malfunctions, the hardwire module in the vehicle is enabled; the hardwire module is a module that unlocks the door handle by sending a hardwire signal to the door handle.

[0010] Optional, also includes:

[0011] Upon receiving an electronic control enable request from the vehicle, the system enables the electronic control unit module and disables the hardwire module.

[0012] Optionally, before the steps of enabling the electronic control unit module and disabling the hardwire module, the method further includes:

[0013] Determine whether the current triggering object of the electronic control enable request is trustworthy; the current triggering object is the object that can generate the electronic control enable request after the current action;

[0014] If the current triggering object is trustworthy, then the steps of enabling the electronic control unit module and disabling the hardwire module are executed.

[0015] Optionally, determining whether the current triggering object of the electronic control enable request is trustworthy includes:

[0016] Determine whether the visual parameters of the current triggering object are consistent with the visual parameters of the preset triggering object of the electronic control enable request; the preset triggering object is an object that can generate the electronic control enable request after a pre-set action;

[0017] If the visual parameters of the current triggering object are consistent with the visual parameters of the preset triggering object, then the current triggering object is determined to be trustworthy.

[0018] Optional, also includes:

[0019] If the current triggering object is untrusted, an error message will be displayed; the error message is used to indicate that the current triggering object is untrusted.

[0020] Optional, also includes:

[0021] Upon receiving a request to disable the vehicle's electronic control system, the system disables the electronic control unit module and enables the hardwired module.

[0022] Optionally, before or after enabling the hardwired module in the vehicle, the method further includes:

[0023] Provide a fault indication; the fault indication is used to indicate that the electronic control unit module has malfunctioned, and / or that the signal transmission of the electronic control unit module has malfunctioned.

[0024] Optionally, after enabling the hardwired module in the vehicle, the method further includes:

[0025] Disable the electronic control unit module.

[0026] A second aspect of this application provides a door handle unlocking device for a vehicle, comprising: an electronic control unit module and a hardwire module; wherein:

[0027] The first output terminal of the electronic control unit module is connected to the first control terminal of the door handle module in the door handle of the vehicle via an electrical signal line.

[0028] The output terminal of the hardwire module is connected to the second control terminal of the door handle module via a hardwire circuit.

[0029] The second output terminal of the electronic control unit module is connected to the input terminal of the hard-wired module via an electrical signal line;

[0030] The input terminal of the electronic control unit module receives the vehicle's electronic control enable request or the vehicle's electronic control disable request via an electrical signal line.

[0031] Both the hardwire module and the electronic control unit module are controlled by the vehicle controller in the vehicle.

[0032] The electronic control unit module is used to execute the door handle unlocking control method of the vehicle as described in any of the first aspects of this application.

[0033] A third aspect of this application provides a vehicle, including a door handle unlocking device as described in the second aspect of this application.

[0034] As can be seen from the above technical solution, the present invention provides a door handle unlocking control method for a vehicle. Since if the vehicle's electronic control unit (ECU) module malfunctions or its signal transmission fails, the door handle cannot receive the electrical signal sent by the ECU module, and therefore cannot unlock using the electrical signal. Therefore, this door handle unlocking control method enables a hardwired module in the vehicle when the electrical signal cannot be used to unlock the door handle. Furthermore, since the door handle can receive the hardwired signal sent by the hardwired module when the electrical signal cannot be used, and thus unlocking can be achieved using the hardwired signal, this door handle unlocking control method can achieve unlocking using the hardwired signal even when the electrical signal cannot be used. Therefore, this door handle unlocking control method improves the unlocking reliability of the door handle. Attached Figure Description

[0035] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0036] Figures 1-8 These are flowchart illustrations of eight implementation methods for unlocking vehicle door handles provided in the embodiments of this application;

[0037] Figures 9-11 These are schematic diagrams illustrating three embodiments of the vehicle door handle unlocking device provided in this application. Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0040] To improve the reliability of vehicle door handle unlocking, this application provides a vehicle door handle unlocking control method, the specific process of which is as follows: Figure 1 As shown, the specific process includes the following:

[0041] S110. Determine whether the electronic control unit module in the vehicle is enabled.

[0042] If the aforementioned electronic control unit module is enabled, then step S120 is executed; if the aforementioned electronic control unit module is not enabled, that is, the aforementioned electronic control unit module is disabled, then the door handle unlocking control method is stopped.

[0043] The aforementioned electronic control unit module is a module that unlocks the door handle by sending an electrical signal to the door handle in the vehicle.

[0044] In one specific example, the electronic control unit module unlocks the door handle by outputting a high-level electrical signal to the door handle.

[0045] In another specific example, the electronic control unit module unlocks the door handle by outputting a low-level electrical signal to the aforementioned door handle.

[0046] It should be noted that the high and low levels are set according to the actual situation, and no specific limitations are made here.

[0047] The above are just two implementation methods for the electronic control unit module to unlock the door handle. No specific limitation is made here, and the method can be determined according to the specific situation. All of them are within the protection scope of this application.

[0048] Furthermore, the fact that the aforementioned electronic control unit module is enabled indicates that the aforementioned electronic control unit module is capable of generating and sending the aforementioned electrical signal to the aforementioned door handle; as for whether to send the aforementioned electrical signal to the aforementioned door handle and when to send the aforementioned electrical signal to the aforementioned door handle, these are already very mature technologies in the prior art, and will not be described in detail here.

[0049] As can be deduced from the above, when the above-mentioned electronic control unit module is enabled, the above-mentioned door handle can receive the above-mentioned electrical signal, and therefore the above-mentioned door handle can be unlocked using the above-mentioned electrical signal; wherein, this method of unlocking the above-mentioned door handle using the above-mentioned electrical signal is called electronic unlocking.

[0050] S120. Determine whether the above-mentioned electronic control unit module has malfunctioned, and / or whether the signal transmission of the above-mentioned electronic control unit module has malfunctioned.

[0051] If the aforementioned electronic control unit module malfunctions, and / or the signal transmission of the aforementioned electronic control unit module malfunctions, then step S130 is executed; if the aforementioned electronic control unit module does not malfunction, and the signal transmission of the aforementioned electronic control unit module does not malfunction, then the door handle unlocking control method is stopped.

[0052] The failure of the aforementioned electronic control unit module indicates that the module is unable to generate the aforementioned electrical signal, or that the generated electrical signal is incorrect. Conversely, it indicates that the module can generate the aforementioned electrical signal, and that the generated electrical signal is correct.

[0053] For example, suppose that outputting a high-level electrical signal to the door handle can unlock the door handle. If the generated electrical signal is high, it means that the generated electrical signal is incorrect. If the generated electrical signal is low, it means that the generated electrical signal is correct.

[0054] In addition, a signal transmission failure of the aforementioned electronic control unit module indicates that the aforementioned electronic control unit module is unable to send the aforementioned electrical signal to the aforementioned door handle, or that the aforementioned electrical signal sent by the aforementioned electronic control unit module to the aforementioned door handle is incorrect. Conversely, it indicates that the aforementioned electronic control unit module can send the aforementioned electrical signal to the aforementioned door handle, and that the aforementioned electrical signal sent by the aforementioned electronic control unit module to the aforementioned door handle is correct.

[0055] For example, assuming the generated electrical signal is high, if the transmitted electrical signal is high, it indicates that the transmitted electrical signal is correct; if the transmitted electrical signal is low, it indicates that the transmitted electrical signal is incorrect.

[0056] As can be deduced from the above, if the above-mentioned electronic control unit module malfunctions and / or the signal transmission of the above-mentioned electronic control unit module malfunctions, the above-mentioned door handle cannot receive the above-mentioned electrical signal, and therefore cannot use the above-mentioned electrical signal to unlock the above-mentioned door handle.

[0057] Optionally, the aforementioned electrical signal can be a CAN signal. In practical applications, it may include, but is not limited to, CAN signals. It is not specifically limited here and can be determined according to the specific circumstances. All of these are within the protection scope of this application.

[0058] S130, Enable the hardwired module in the aforementioned vehicle.

[0059] The hardwire module is a module that unlocks the door handle by sending a hardwire signal to the door handle.

[0060] In one specific example, the hardwired module unlocks the door handle by outputting a high-level hardwired signal to the aforementioned door handle.

[0061] In another specific example, the hardwired module unlocks the door handle by outputting a low-level hardwired signal to the aforementioned door handle.

[0062] It should be noted that the high and low levels are set according to the actual situation, and no specific limitations are made here.

[0063] The above are just two implementation methods for unlocking the door handle using a hard-wired module. No specific limitations are made here, and the method can be determined according to the specific circumstances. All of them are within the protection scope of this application.

[0064] Furthermore, the enabling of the aforementioned hardwire module indicates that the hardwire module is capable of generating and sending the aforementioned hardwire signal to the aforementioned door handle. As for whether to send the aforementioned hardwire signal to the aforementioned door handle and when to send the aforementioned hardwire signal to the aforementioned door handle, these are already well-established technologies and will not be described in detail here.

[0065] As can be deduced from the above, when the hardwire module is enabled, the door handle can receive the hardwire signal, and therefore the door handle can be unlocked using the hardwire signal; this method of unlocking the door handle using the hardwire signal is called hardwire unlocking.

[0066] As described above, when the electronic control unit module malfunctions and / or the signal transmission of the electronic control unit module fails, the door handle cannot be unlocked using the electrical signal. Therefore, when the door handle unlocking control method cannot unlock the door handle using the electrical signal, it enables the hardwire module. Furthermore, as described above, when the hardwire module is enabled, the door handle can be unlocked using the hardwire signal. Thus, the door handle unlocking control method can unlock the door handle using the hardwire signal when the electrical signal cannot be used, thereby improving the unlocking reliability of the door handle.

[0067] Another embodiment of this application provides another implementation of the vehicle door handle unlocking control method, the specific process of which is as follows: Figure 2 (To simplify the view, in) Figure 2 (Steps S110-S130 are omitted in the text). Based on the above embodiment, this implementation also includes the following steps:

[0068] S210. Determine whether a vehicle's electronic control enable request has been received.

[0069] If the above-mentioned electronic control enable request is received, then step S220 is executed; if the above-mentioned electronic control enable request is not received, then the process returns to step S210.

[0070] Receiving the aforementioned electronic control enable request indicates that the user has a need to use electronic unlocking; conversely, not receiving the request indicates that the user does not have a need to use electronic unlocking.

[0071] In a specific example, the current triggering object of the above electronic control enable request is the icon on the screen in the vehicle that is being clicked at this time.

[0072] The current triggering object of the above-mentioned electronic control enable request refers to the object that can generate the above-mentioned electronic control enable request after the current action.

[0073] For example, suppose the icon being clicked on the screen in the vehicle is icon A, then icon A is the current triggering object of the aforementioned electronic control enable request.

[0074] Optionally, the screen in the vehicle can be a central control screen. In practical applications, it may include, but is not limited to, the following: the specific screen may be selected depending on the circumstances, and all of these are within the scope of protection of this application.

[0075] In another specific example, the current triggering object of the above electronic control enable request is the mechanical button that is pressed in the vehicle at this time.

[0076] For example, assuming the mechanical button being pressed in the vehicle at this moment is mechanical button B, then mechanical button B is the current triggering object of the aforementioned electronic control enable request.

[0077] The two examples above only illustrate two implementation methods of the current triggering object of the above-mentioned electronic control enable request. In practical applications, there are other methods, including but not limited to these. No specific limitation is made here. The specific method can be determined according to the specific situation. All of them are within the protection scope of this application.

[0078] S220. Enable the above-mentioned electronic control unit module and disable the above-mentioned hard-wire module.

[0079] The fact that the aforementioned hardwired module is disabled indicates that the hardwired module cannot generate or send the aforementioned hardwired signal to the aforementioned door handle.

[0080] It should be noted that the enabling of the above-mentioned electronic control unit module has been explained in detail above, and will not be repeated here.

[0081] As can be deduced from the above, when the above-mentioned electronic control unit module is enabled and the above-mentioned hard wire module is disabled, the above-mentioned door handle can receive the above-mentioned electrical signal but cannot receive the above-mentioned hard wire signal. Therefore, the above-mentioned door handle can only be unlocked by the above-mentioned electrical signal, and cannot be unlocked by the above-mentioned hard wire signal.

[0082] In this embodiment, upon receiving the aforementioned electronic control enable request, the door handle can only be unlocked using the aforementioned electrical signal, and cannot be unlocked using the aforementioned hard-wired signal. In other words, in this case, only electronic unlocking can be used, and hard-wired unlocking cannot be used. Therefore, to a certain extent, this avoids the door handle receiving both the aforementioned hard-wired signal and the aforementioned electrical signal simultaneously, thereby preventing the situation where the hard-wired signal and the aforementioned electrical signal control the door handle in opposite ways, and thus improving the reliability of unlocking the door handle.

[0083] The above is only one implementation method of the vehicle door handle unlocking control method. It is not specifically limited here and can be determined according to the specific situation. All of them are within the protection scope of this application.

[0084] Another embodiment of this application also provides another implementation of the vehicle door handle unlocking control method, which is applicable when the current triggering object of the received electronic control enable request is an icon on the screen in the vehicle that is currently being clicked; the specific process of this implementation is as follows: Figure 3 (To simplify the view, in) Figure 3 (Steps S110 to S130 are omitted in the text). As shown in this embodiment, before step S220 in the previous embodiment, the following steps are also included:

[0085] S310. Determine whether the current triggering object of the above-mentioned electronic control enable request is trustworthy.

[0086] If the current triggering object of the above-mentioned electronic control enable request is trustworthy, then proceed to step S220; if the current triggering object of the above-mentioned electronic control enable request is not trustworthy, then return to proceed to step S210.

[0087] It should be noted that the current triggering object of the above-mentioned electronic control enable request has been described in detail above, and will not be repeated here.

[0088] If the current triggering object of the aforementioned electronic control enable request is trustworthy, it indicates that the current triggering object of the aforementioned electronic control enable request has not been tampered with; otherwise, it indicates that the current triggering object of the aforementioned electronic control enable request has been tampered with.

[0089] In this embodiment, the electronic control unit module is enabled only if the current triggering object of the above-mentioned electronic control enable request is trustworthy, that is, only if the current triggering object of the above-mentioned electronic control enable request has not been tampered with. Therefore, to a certain extent, it is guaranteed that the unlocking method of the above-mentioned door handle can only be switched to electronic unlocking under the above-mentioned circumstances, thereby improving the security of the door handle unlocking control method.

[0090] The above is only one implementation method of the vehicle door handle unlocking control method. It is not specifically limited here and can be determined according to the specific situation. All of them are within the protection scope of this application.

[0091] Another embodiment of this application provides a specific implementation of step S310, the specific process of which is as follows: Figure 4 (To simplify the view, in) Figure 4 (Steps S110-S130 are omitted) As shown in the figure, the specific steps include:

[0092] S410. Determine whether the visual parameters of the current triggering object of the above-mentioned electronic control enable request are consistent with the visual parameters of the preset triggering object of the above-mentioned electronic control enable request.

[0093] If the visual parameters of the current triggering object of the above-mentioned electronic control enable request are consistent with the visual parameters of the preset triggering object of the above-mentioned electronic control enable request, then step S420 is executed; if the visual parameters of the current triggering object of the above-mentioned electronic control enable request are not consistent with the visual parameters of the preset triggering object of the above-mentioned electronic control enable request, then step S430 is executed.

[0094] It should be noted that the current triggering object of the above-mentioned electronic control enable request has been described in detail above, and will not be repeated here.

[0095] The preset trigger object for the aforementioned electronic control enable request is an object that can generate the aforementioned electronic control enable request after a pre-defined action.

[0096] In addition, the visual parameters of the triggering object are parameters that characterize the visual effect of the triggering object, such as pixels, RGB, color, coordinates, etc. As for the specific visual parameters of the triggering object, they are well-established in the existing technology and will not be described in detail here.

[0097] It should be noted that the visual parameters of the preset trigger object of the above-mentioned electronic control enable request are pre-stored, while the visual parameters of the current trigger object of the above-mentioned electronic control enable request are obtained by detection. As for how to pre-select and store the visual parameters of the preset trigger object of the above-mentioned electronic control enable request and how to detect the visual parameters of the current trigger object of the above-mentioned electronic control enable request, these are already very mature technologies and will not be elaborated here.

[0098] S420. Determine that the aforementioned currently triggered object is trustworthy.

[0099] S430, Determine that the currently triggered object is untrustworthy.

[0100] For example, suppose icon A is the current triggering object of the above-mentioned electronic control enable request, and icon B is the preset triggering object of the above-mentioned electronic control enable request. If the pixel points, RGB values, color, and coordinates of icon A are the same as those of icon B, then icon A is considered trustworthy.

[0101] The above is only one specific implementation of step S310. In practical applications, it includes, but is not limited to, this. It can be determined according to the specific situation, and all are within the protection scope of this application.

[0102] Another embodiment of this application provides yet another implementation of the vehicle door handle unlocking control method, which is applicable when the current triggering object of the received electronic control enable request is an icon on the screen in the vehicle that is currently being clicked; the specific process of this implementation is as follows: Figure 5 (To simplify the view, in) Figure 5 (Steps S110-S130 are omitted in the original text). In this embodiment, after determining in the previous embodiment that the triggering object of the aforementioned electronic control enable request is untrustworthy, the following steps are also included:

[0103] S320, display an error message.

[0104] The error message indicates that the current triggering object of the above-mentioned electronic control enable request is untrusted, that is, it indicates that the current triggering object of the received electronic control enable request has been tampered with.

[0105] In a specific example, if the current triggering object of the above electronic control enable request is the icon on the screen in the vehicle that is currently being clicked, the fault message can be: gray out the icon on the screen in the vehicle that is currently being clicked.

[0106] The above is only one implementation of the error message. In practical applications, there are other implementations, including but not limited to this one. No specific limitation is made here. The implementation can be determined according to the specific circumstances, and all are within the protection scope of this application.

[0107] The above is only one implementation method of the vehicle door handle unlocking control method. It is not specifically limited here and can be determined according to the specific situation. All of them are within the protection scope of this application.

[0108] Another embodiment of this application provides another implementation of the vehicle door handle unlocking control method, the specific process of which can be found in [reference needed]. Figure 6 ( Figure 6 Only Figure 1 Based on this, to simplify the view, on Figure 5 (Steps S110 to S130 are omitted in the original text). This embodiment, based on the above embodiment, also includes the following steps:

[0109] S510. Determine whether a vehicle electronic control disable request has been received.

[0110] If the above-mentioned electronic control disable request is received, then step S520 is executed; if the above-mentioned electronic control disable request is not received, then return to step S510.

[0111] The aforementioned electronic control disable request is used to request the electronic control unit module to be disabled. In other words, upon receiving the aforementioned electronic control disable request, the electronic control unit module is controlled to be disabled.

[0112] In addition, the aforementioned electronic control disable request is generated when it is detected that the user has a need to enable the aforementioned hardwired module; in other words, it is generated when it is detected that the user has a need to unlock using the hardwired module.

[0113] In a specific example, a user's need to use hard-wire unlock is identified by recognizing whether the user clicks on an icon on a screen in the vehicle that indicates the use of hard-wire unlock; for example, if the user is detected clicking on the icon on the screen in the vehicle, it is recognized that the user has a need to use hard-wire unlock.

[0114] It should be noted that if the user's need for electronic unlocking is determined by whether they click the icon indicating electronic unlocking on the vehicle's screen, then the icons indicating electronic unlocking and hard-wire unlocking can be combined into one icon, with the two different states of the icon replacing the original two icons. Since clicking the combined icon once is equivalent to clicking each of the original two icons separately, the user's operation is simplified. However, the possibility of not combining the two icons into one cannot be ruled out. As for how to replace the original two icons with their two different states, this is already a well-established technology and will not be described in detail here.

[0115] In another specific example, the user's need to use hard-wire unlock is identified by recognizing whether the user presses a mechanical button that indicates the use of hard-wire unlock; for example, if the user presses a mechanical button that indicates the use of hard-wire unlock, then the user's need to use hard-wire unlock is identified.

[0116] It should be noted that if the user's need for electronic unlocking is determined by whether the user presses the mechanical button indicating electronic unlocking, then the mechanical button indicating electronic unlocking and the mechanical button indicating hard-wire unlocking can be combined into one mechanical button, and the two different states of the mechanical button can replace the original two mechanical buttons. Since clicking the combined mechanical button once is equivalent to clicking each of the original two mechanical buttons once, the user's operation is simplified. However, the possibility of not combining the two mechanical buttons into one cannot be ruled out. As for how to replace the original two mechanical buttons with the two different states of the mechanical button, the existing technology is already very mature, and it will not be described in detail here.

[0117] The two examples above only illustrate two ways to identify whether there is a need to use hard wire unlocking. In practical applications, there are other methods, including but not limited to these. No specific limitation is made here. It depends on the specific situation and all are within the protection scope of this application.

[0118] S520: Disable the above-mentioned electronic control unit module and enable the above-mentioned hard-wired module.

[0119] The fact that the aforementioned electronic control unit module is disabled indicates that the aforementioned electronic control unit module is unable to generate and send the aforementioned electrical signals to the aforementioned door handle.

[0120] It should be noted that the above-mentioned hard-wired module enable has already been explained in detail above, and will not be repeated here.

[0121] As can be deduced from the above, when the above-mentioned electronic control unit module is disabled and the above-mentioned hard-wire module is enabled, the above-mentioned door handle can receive the above-mentioned hard-wire signal but cannot receive the above-mentioned electrical signal. Therefore, the above-mentioned door handle can only be unlocked by using the above-mentioned hard-wire signal, and cannot be unlocked by using the above-mentioned electrical signal.

[0122] In this embodiment, when the above-mentioned electronic control disable request is received, the door handle can only be unlocked using the above-mentioned hard wire signal, and cannot be unlocked using the above-mentioned electrical signal. In other words, in this case, only hard wire unlocking can be used, and electronic unlocking cannot be used. Therefore, to a certain extent, the door handle is prevented from receiving both the above-mentioned hard wire signal and the above-mentioned electrical signal at the same time, thereby avoiding the situation where the control of the door handle by the above-mentioned hard wire signal and the above-mentioned electrical signal is opposite, and thus improving the reliability of unlocking the door handle.

[0123] The above is only one implementation method of the vehicle door handle unlocking control method. It is not specifically limited here and can be determined according to the specific situation. All of them are within the protection scope of this application.

[0124] Another embodiment of this application provides another implementation of the vehicle door handle unlocking control method, the specific process of which can be found in [reference needed]. Figure 7 ( Figure 7 Only Figure 1 Based on this, the presentation will be carried out. Figure 7 (Taking only step S610 after step S130 as an example, this embodiment further includes the following steps before or after step S130 in the above embodiment:)

[0125] S610, provide fault indication.

[0126] The fault indication is used to indicate that the above-mentioned electronic control unit module has malfunctioned, and / or that the signal transmission of the above-mentioned electronic control unit module has malfunctioned.

[0127] In a specific example, if the triggering object of the received electronic control enable request is an icon that is currently being clicked on the screen in the vehicle, the fault message can be: the icon that is currently being clicked on the screen in the vehicle is grayed out.

[0128] The above is only one implementation method for fault indication. In practical applications, there are other methods, including but not limited to this one. No specific limitation is made here. It can be determined according to the specific situation, and all are within the protection scope of this application.

[0129] The above is only one implementation method of the vehicle door handle unlocking control method. It is not specifically limited here and can be determined according to the specific situation. All of them are within the protection scope of this application.

[0130] Another embodiment of this application provides another implementation of the vehicle door handle unlocking control method, the specific process of which can be found in [reference needed]. Figure 8 ( Figure 8 Only Figure 1 Based on the above embodiment (which is presented here), this embodiment, after step S130 in the above embodiment, further includes the following steps:

[0131] S710, disable the above-mentioned electronic control unit module.

[0132] It should be noted that the above-mentioned disabling of the electronic control unit module has already been explained in detail above, and will not be repeated here.

[0133] As can be deduced from the above, when the above-mentioned electronic control unit module is disabled and the above-mentioned hard-wire module is enabled, the above-mentioned door handle can receive the above-mentioned hard-wire signal but cannot receive the above-mentioned electrical signal. Therefore, the above-mentioned door handle can only be unlocked by using the above-mentioned hard-wire signal, and cannot be unlocked by using the above-mentioned electrical signal.

[0134] It should be noted that if steps S610 and S710 are included after step S130, step S610 is preferably after step S710, but other possibilities are not excluded.

[0135] In this embodiment, step S710 is executed after step S130. This is equivalent to executing step S710 when the above-mentioned electronic control unit module fails and / or the signal transmission of the above-mentioned electronic control unit module fails. This further ensures that the above-mentioned door handle cannot receive the above-mentioned electrical signal, thereby further improving the reliability of the door handle unlocking control method.

[0136] Another embodiment of this application provides a door handle unlocking device for a vehicle, the specific structure of which is as follows: Figure 9 As shown, it specifically includes: hard-wired module 10 and electrical control unit module 20.

[0137] The first output terminal of the electronic control unit module 20 is connected to the first control terminal of the door handle module 30 in the vehicle's door handle via an electrical signal line; the output terminal of the hard-wired module 10 is connected to the second control terminal of the door handle module 30 via a hard-wired circuit; and the second output terminal of the electronic control unit module 20 is connected to the input terminal of the hard-wired module 10 via an electrical signal line.

[0138] Optionally, the electrical signal line can be a CAN bus. In practical applications, this may include, but is not limited to, the following: the specific application may be chosen based on the specific circumstances. All of these are within the scope of protection of this application.

[0139] The input terminal of the electronic control unit module 20 receives the vehicle's electronic control enable request or the vehicle's electronic control disable request via an electrical signal line; the electronic control unit module 20 is used to execute the vehicle's door handle unlocking control method as provided in the above embodiments.

[0140] When the electronic control unit module 20 receives an electronic control enable request, the electronic control unit module 20 enables itself and disables the hard-wired module 10; when the electronic control unit module 20 receives an electronic control disable request, the electronic control unit module 20 disables itself and enables the hard-wired module 10.

[0141] The electronic control unit module 20 enables the hard-wired module 10 by outputting an enable signal to the hard-wired module 10, and conversely, disables the hard-wired module 10 by not outputting an enable signal to the hard-wired module 10.

[0142] The electronic control unit module 20 outputs an electrical signal to the door handle module 30 to unlock or lock the door handle.

[0143] In a specific example, the electronic control unit module 20 unlocks the door handle by outputting a high-level electrical signal to the door handle module 30, and locks the door handle by outputting a low-level electrical signal to the door handle module 30; the high and low levels are set according to the actual situation and are not specifically limited here.

[0144] In another specific example, the electronic control unit module 20 unlocks the door handle by outputting a low-level electrical signal to the door handle module 30, and locks the door handle by outputting a high-level electrical signal to the door handle module 30; the high and low levels are set according to the actual situation and are not specifically limited here.

[0145] The above are just two implementation methods for the electronic control unit module 20 to unlock or lock the door handle. No specific limitation is made here. It can be determined according to the specific situation. All of them are within the protection scope of this application.

[0146] The hardwire module 10 unlocks or locks the door handle by outputting a hardwire signal to the door handle module 30.

[0147] In a specific example, the hardwire module 10 unlocks the door handle by outputting a high-level hardwire signal to the door handle module 30, and locks the door handle by outputting a low-level hardwire signal to the door handle module 30; the high and low levels are set according to the actual situation and are not specifically limited here.

[0148] In another specific example, the hardwire module 10 unlocks the door handle by outputting a low-level hardwire signal to the door handle module 30, and locks the door handle by outputting a high-level hardwire signal to the door handle module 30; the high and low levels are set according to the actual situation and are not specifically limited here.

[0149] The above are just two implementation methods for the hardwire module 10 to unlock or lock the door handle. No specific limitation is made here. It can be determined according to the specific situation. All of them are within the protection scope of this application.

[0150] In addition, both the hardwire module 10 and the electronic control unit module 20 are controlled by the vehicle controller in the vehicle.

[0151] Taking the unlocking of the door handle using a high-level hardwired signal as an example, after the hardwired module 10 is enabled, when the vehicle controller detects the need to unlock the door handle, the vehicle controller controls the hardwired module 10 to send a high-level hardwired signal to the door handle module 30 to unlock the door handle; when the vehicle controller does not detect the need to unlock the door handle, the vehicle controller controls the hardwired module 10 to send a low-level hardwired signal to the door handle module 30 to lock the door handle.

[0152] It should be noted that if a low-level hardwired signal unlocks the door handle, the vehicle controller's control of the hardwired module 10 will be the opposite of that described above, which can be deduced and will not be elaborated here. In addition, the high and low levels of the hardwired signal can be set according to the actual situation, and no specific limitation is made here.

[0153] Taking the unlocking of the door handle with a high-level electrical signal as an example, when the vehicle controller detects the need to unlock the door handle, the vehicle controller controls the electronic control unit module 20 to send a high-level electrical signal to the door handle module 30 to unlock the door handle; when the vehicle controller does not detect the need to unlock the door handle, the vehicle controller controls the electronic control unit module 20 to send a low-level electrical signal to the door handle module 30 to lock the door handle.

[0154] It should be noted that if a low-level electrical signal unlocks the door handle, the vehicle controller's control of the hardwire module 10 will be the reverse of the above process, which can be derived and will not be elaborated here. In addition, the high and low levels of the hardwire signal can be set according to the actual situation, and no specific limitation is made here.

[0155] Another embodiment of this application provides one implementation of the hardwire module 10, the specific structure of which is as follows: Figure 10 As shown, it specifically includes: a first battery 11, a hardware switch 12, and a CAN signal parsing module 13.

[0156] The output terminal of the first battery 11 is connected to one end of the hardware switch 12, and the other end of the hardware switch 12 serves as the output terminal of the hardwire module 10; the control terminal of the first power supply is connected to the output terminal of the CAN signal parsing module 13, and the input terminal of the CAN signal parsing module 13 serves as the input terminal of the hardwire module 10.

[0157] The CAN signal parsing module 13 is used to parse the signals sent by the electronic control unit module 20 and send the parsing results to the first battery 11. When the CAN signal parsing module 13 outputs an enable signal from the electronic control unit module 20, the first battery 11 outputs, that is, the hard-wired module 10 is enabled. When the CAN signal parsing module 13 outputs a non-enable signal from the electronic control unit module 20, the first battery 11 does not output, that is, the hard-wired module 10 is disabled.

[0158] In addition, the hardware switch 12 is controlled by the vehicle controller in the vehicle.

[0159] Taking the door handle unlocking achieved by a high-level hard-wire signal as an example, when the first battery 11 is outputting, the vehicle controller controls the hardware switch 12 to close and outputs a high-level hard-wire signal when it detects a need to unlock the door handle; when it does not detect a need to unlock the door handle, it controls the hardware switch 12 to open and outputs a low-level hard-wire signal.

[0160] It should be noted that if a low-level hardwired signal unlocks the door handle, the vehicle controller's control of the hardwired switch is the opposite of that described above, which can be derived and will not be elaborated here.

[0161] The above is only one implementation of the hardwire module 10. In practical applications, there are other implementations, including but not limited to this one. No specific limitation is made here. The implementation can be determined according to the specific circumstances, and all of them are within the protection scope of this application.

[0162] Another embodiment of this application provides one implementation of the electronic control unit module 20, the specific structure of which is as follows: Figure 11 As shown, it specifically includes: a second battery 21, an electronic control signal transmission module 22, and an electronic control fault monitoring module 23.

[0163] The input terminal of the electronic control fault monitoring module 23 serves as the input terminal of the electronic control unit module 20; the first output terminal of the electronic control fault monitoring module 23 is connected to the control terminal of the second battery 21, the output terminal of the second battery 21 is connected to the input terminal of the electronic control signal sending module 22, the output terminal of the electronic control signal sending module 22 serves as the first output terminal of the electronic control unit module 20; the second output terminal of the electronic control fault monitoring module 23 serves as the second output terminal of the electronic control unit module 20.

[0164] When the electronic control fault monitoring module 23 receives an electronic control enable request, it outputs an enable signal to the second battery 21 but does not output an enable signal to the hardwire module, thus enabling the electronic control unit module 20 and disabling the hardwire module 10. When the electronic control fault monitoring module 23 receives an electronic control enable request, it does not output an enable signal to the second battery 21 but outputs an enable signal to the hardwire module, thus disabling the electronic control unit module 20 and enabling the hardwire module 10.

[0165] When the electronic control fault monitoring module 23 outputs an enable signal to the second battery 21, the second battery 21 outputs an enable signal, thus enabling the electronic control unit module 20; when the electronic control fault monitoring module 23 does not output an enable signal to the second battery 21, the second battery 21 does not output an enable signal, thus disabling the electronic control unit module 20.

[0166] The electronic control fault monitoring module 23 is used to execute the door handle unlocking control method of the vehicle as provided in the above embodiment.

[0167] In addition, the electronic control signal transmission module 22 is controlled by the vehicle controller.

[0168] Taking the unlocking of the door handle using a high-level hard-wired signal as an example, when the second battery 21 is outputting, if the vehicle controller detects a need to unlock the door handle, the vehicle controller controls the electronic control signal sending module 22 to send a high-level electrical signal, which causes the electronic control unit module 20 to generate and send a high-level electrical signal to the door handle module 30; if the vehicle controller does not detect a need to unlock the door handle, the vehicle controller controls the electronic control signal sending module 22 to send a low-level electrical signal, which causes the electronic control unit module 20 to generate and send a low-level electrical signal to the door handle module 30.

[0169] It should be noted that if a low-level electrical signal unlocks the door handle, the vehicle controller's control of the electronic control signal sending module 22 will be the opposite of the above, which can be deduced and will not be elaborated here.

[0170] The above is only one implementation of the electronic control unit module 20. In practical applications, there are other implementations, including but not limited to this one. No specific limitation is made here. The implementation can be determined according to the specific circumstances, and all of them are within the protection scope of this application.
