[0002] With the development of electric, intelligent and networked automobile technologies, the number of corresponding control modules in automobiles has gradually increased. Among them, some electronic modules need to maintain a long-term power supply state. In this process, due to the characteristics of some electronic components themselves, electromagnetic noise will be generated, and some electronic modules will be in an electromagnetic noise environment. When the car is in operation, the electromagnetic noise environment in which the electronic modules are located will be more complex, and the complex electromagnetic noise environment will affect the normal function of the vehicle, such as the inability to unlock the vehicle with the key or the lack of tire pressure display on the instrument panel. In severe cases, it may cause the vehicle to stall abnormally.

[0003] To reduce the impact of electromagnetic noise on vehicle functions, related technologies conduct electromagnetic compatibility (EMC) testing on the installation location of vehicle components and wiring harness routing during the early stages of vehicle development. This assesses the vehicle's ability to withstand electromagnetic noise, and EMC issues are addressed by modifying component software or hardware. However, after a vehicle leaves the factory, it's impossible to assess the electromagnetic noise environment it's exposed to, meaning that real-time vehicle electromagnetic status monitoring is impossible. Summary of the Invention

[0017] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0018] With the development of electric, intelligent and networked automobile technologies, the number of corresponding control modules in automobiles has gradually increased. Among them, some electronic modules need to maintain a long-term power supply state. In this process, due to the characteristics of some electronic components themselves, electromagnetic noise will be generated, and some electronic modules will be in an electromagnetic noise environment. When the car is in operation, the electromagnetic noise environment in which the electronic modules are located will be more complex, and the complex electromagnetic noise environment will affect the normal function of the vehicle, such as the inability to unlock the vehicle with the key or the lack of tire pressure display on the instrument panel. In severe cases, it may cause the vehicle to stall abnormally.

[0019] In related technologies, in the early stages of vehicle development, electromagnetic compatibility (EMC) tests are performed on the installation locations of vehicle components, wiring harness directions, etc., to assess the vehicle's ability to withstand electromagnetic noise, and to resolve vehicle electromagnetic compatibility issues by changing the software or hardware of the components. However, after the vehicle leaves the factory and is in a complex electromagnetic environment, it is only possible to check if the vehicle has experienced abnormal electromagnetic noise. It is impossible to detect the vehicle's electromagnetic status in real time, nor is it possible to take timely measures to prevent interference with the functions of related functional modules.

[0020] To improve the above-mentioned problems, embodiments of the present application provide a vehicle electromagnetic state detection method, device, vehicle, and storage medium. The method comprises: acquiring electromagnetic information of the vehicle; when it is detected that the electromagnetic information exceeds a first preset threshold, acquiring abnormal frequency band information; determining the functional module corresponding to the abnormal frequency band information; and controlling the functional module to enter an enhanced anti-interference mode. Thus, by acquiring electromagnetic information of the vehicle, when the electromagnetic information of the vehicle exceeds a first preset threshold, acquiring abnormal frequency band information, determining the corresponding functional module based on the abnormal frequency band information, thereby determining that the relevant functional module may be interfered with by electromagnetic noise, and controlling the corresponding functional module to enter an enhanced anti-interference mode, thereby achieving real-time detection of the vehicle's electromagnetic state, while reducing the situation where the functional module is interfered with by electromagnetic noise and cannot perform the corresponding function.

[0021] See also Figure 1 , Figure 1 A flow chart of a vehicle electromagnetic state detection method provided in an embodiment of the present application is shown. The method may include steps 110 to 140.

[0022] In step 110 , electromagnetic information of the vehicle is acquired.

[0023] In the embodiments of the present application, electromagnetic information may include electromagnetic information from both the exterior and interior of the vehicle. Electromagnetic information refers to certain clutter signals caused by electromagnetic wave signals due to electromagnetic fields. Electromagnetic information from within the vehicle is typically electromagnetic noise generated by the characteristics of internal electronic components. Electromagnetic information from outside the vehicle typically refers to electromagnetic noise in the vehicle's environment. When a vehicle is in a complex electromagnetic information environment, electromagnetic information can interfere with the ability of relevant vehicle modules to receive signals, and may even cause the relevant modules to malfunction, such as causing a key to fail to unlock the vehicle.

[0024] In an embodiment of the present application, when it is detected that the power source is in a working state, at least one electromagnetic information outside or inside the vehicle is obtained; wherein, the power source is associated with a power supply module composed of a generator and a battery, or a power supply module composed of a battery alone; when the vehicle is in a running state, the vehicle is powered by a power supply module composed of a generator and a battery; and when the vehicle is in an off state, the vehicle is generally powered by a power supply module composed of a battery alone to provide power for modules inside the vehicle that require long-term power supply, such as the vehicle's anti-theft module and other modules; due to the characteristics of the internal electronic components themselves, electromagnetic noise will be generated inside the vehicle; and as the vehicle is in a running state, more and more internal electronic components are involved in the operation of the vehicle, and more and more electromagnetic noise is generated inside the vehicle. The environment outside the vehicle may change, and the electromagnetic information in the environment in which the vehicle is located is also changing.

[0025] In an embodiment of the present application, electromagnetic information inside or outside the vehicle can be obtained in real time to achieve real-time detection of the electromagnetic noise situation in which the vehicle is located; in other embodiments, electromagnetic information inside or outside the vehicle can also be obtained periodically.

[0026] In step 120, when it is detected that the electromagnetic information exceeds a first preset threshold, abnormal frequency band information is acquired.

[0027] In an embodiment of the present application, the first preset threshold indicates the critical value of the electromagnetic noise that the corresponding functional module can withstand. The value of the first preset threshold can be calibrated and confirmed based on the actual application of the functional module; when the electromagnetic information exceeds the first preset threshold, it indicates that the electromagnetic noise environment in which the vehicle is located may interfere with the normal operation of the relevant functional modules of the vehicle. For example, when the electromagnetic information exceeds the electromagnetic noise interference range that the navigation function module can withstand, the navigation function of the navigation function module may fail, and the navigation function module will not be able to provide navigation services to passengers.

[0028] In an embodiment of the present application, the abnormal frequency band information indicates the frequency band information corresponding to the abnormality of the functional module. The frequency band information may include frequency band information such as navigation band, tire pressure monitoring band or radio band. The abnormal frequency band information may include abnormal frequency band information such as navigation abnormal band, tire pressure monitoring abnormal band or radio abnormal band.

[0029] In an embodiment of the present application, when it is detected that the electromagnetic information exceeds a first preset threshold, the vehicle can also broadcast the abnormal situation through voice to remind the user that the electromagnetic abnormal situation is currently in place; the electromagnetic abnormal situation can also be displayed on the vehicle display screen to prompt safe driving; and a reminder message can also be sent to the background based on the telematics box (T-BOX); this can serve as a reminder to the customer and improve the user experience.

[0030] In step 130 , the functional module corresponding to the abnormal frequency band information is determined.

[0031] In an embodiment of the present application, corresponding abnormal frequency band information ranges can be associated with different functional modules. For example, the navigation module corresponds to the first abnormal frequency band range, and the radio functional module corresponds to the second abnormal frequency band range. In this way, the relevant functional modules are determined based on the abnormal frequency band information, that is, the functional modules that may be affected by electromagnetic noise are determined. For example, when the abnormal frequency band information is navigation abnormal frequency band information, the functional module corresponds to the navigation functional module.

[0032] In step 140 , the functional module is controlled to enter an anti-interference enhancement mode.

[0033] In an embodiment of the present application, relevant functional modules are controlled to enter an enhanced anti-interference mode to reduce the impact of electromagnetic noise on the relevant functional modules and their inability to perform corresponding functions, such as reducing the situation where the navigation functional module is interfered with by electromagnetic noise and cannot provide navigation functions. When a functional module enters the enhanced anti-interference mode, the anti-electromagnetic interference capability of the functional module can be enhanced by adjusting the signal strength of the corresponding module, or by increasing the strength of the signals received and transmitted by the vehicle antenna and the functional module.

[0034] From the above, it can be seen that by acquiring the electromagnetic information of the vehicle, the collected electromagnetic information is compared with the first preset threshold value. When it is detected that the electromagnetic information in the vehicle's environment exceeds the first preset threshold value, the abnormal frequency band information is acquired, and the corresponding functional module is determined based on the abnormal frequency band information to determine the relevant functional module that may be interfered with by electromagnetic noise, and control it to enter the anti-interference enhancement mode to enhance the ability of the functional module to be interfered with by electromagnetic noise, and reduce the situation where the functional module is interfered with by electromagnetic noise and cannot realize the corresponding function.

[0035] In combination with the method described in the above embodiment, the following examples are given to further illustrate the method in detail.

[0036] See also Figure 2 , Figure 2 A scenario schematic diagram of a vehicle electromagnetic state detection system provided in an embodiment of the present application is shown, including an electromagnetic environment acquisition sensor and an electromagnetic environment monitoring module; the electromagnetic environment acquisition sensor and the electromagnetic environment monitoring module can communicate using a wireless or wired connection method, wherein the electromagnetic environment acquisition sensor can be used to collect electromagnetic information inside or outside the vehicle and transmit the electromagnetic information to the electromagnetic environment monitoring module. The number of electromagnetic environment acquisition sensors can include one or more. In the embodiment of the present application, the number of electromagnetic environment acquisition sensors is three, which are installed at the front, middle and rear positions of the vehicle respectively. This application does not limit the number of electromagnetic environment acquisition sensors.

[0037] The electromagnetic environment monitoring module can be integrated into modules such as the gateway or domain controller, or it can be a separate module. When the electromagnetic environment monitoring module detects that the electromagnetic signal exceeds the first preset threshold, the electromagnetic environment monitoring module obtains the abnormal frequency band information and transmits it to the corresponding functional module through the controller area network (CAN). The corresponding functional module enters the anti-interference enhancement mode. Among them, the functional modules can include tire pressure monitoring functional modules, navigation functional modules, radio functional modules or keyless unlocking functional modules, etc.

[0038] It should be noted that Figure 2 The scenario diagram of the vehicle electromagnetic state detection system shown is only an example. The vehicle electromagnetic state detection system and scenario described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided by the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the vehicle electromagnetic state detection system and the emergence of new business scenarios, the technical solution provided by the embodiment of the present application is also applicable to similar technical problems.

[0039] It should be noted that the serial numbers of the following embodiments are not intended to limit the preferred order of the embodiments.

[0040] See also Figure 3 , Figure 3 Another flow chart of a vehicle electromagnetic state detection method provided in an embodiment of the present application is shown. The method may include steps 210 to 270.

[0041] In step 210 , when it is detected that the power source is in the working state, the electromagnetic environment collection sensor collects at least one electromagnetic information outside the vehicle or inside the vehicle.

[0042] The power source is associated with a power supply module composed of a generator and a battery, or a power supply module composed solely of a battery. When the vehicle is in the off state, the vehicle is generally powered by the power supply module composed solely of the battery. Modules operating within the vehicle generally require long-term power supply, such as anti-theft modules and modules with memory functions. When the vehicle is in operation, the vehicle is powered by the power supply module composed of a generator and a battery. At this time, the external environment of the vehicle may change, that is, the geographical location of the vehicle may change. As a result, the electromagnetic information outside the vehicle also changes with the changes in the vehicle's environment. In addition, as more and more electronic components are involved in the operation of the vehicle, the electromagnetic information inside the vehicle also changes. Complex electromagnetic information can interfere with the normal operation of related modules.

[0043] When the power source is in working condition, the electromagnetic environment acquisition sensor collects electromagnetic information outside or inside the vehicle. The electromagnetic information indicates certain clutter signals caused by the electromagnetic wave signal due to the electromagnetic field. In an embodiment of the present application, the electromagnetic environment acquisition sensor can collect electromagnetic information outside or inside the vehicle in real time. In other embodiments, the electromagnetic environment acquisition sensor can also periodically collect electromagnetic information outside or inside the vehicle and transmit the collected electromagnetic information to the electromagnetic environment monitoring module.

[0044] In step 220 , the electromagnetic environment monitoring module compares the collected electromagnetic information with a first preset threshold value.

[0045] Among them, the value of the first preset threshold can be calibrated and confirmed according to the actual application of the functional module. It is worth noting that the first preset threshold can include multiple specific values ​​or multiple ranges, and each specific value corresponds to the critical value of the electromagnetic noise that the relevant functional module can withstand, such as the navigation module corresponds to the first critical value, the radio functional module corresponds to the second critical value, and so on.

[0046] In step 230 , when it is detected that the electromagnetic information exceeds a first preset threshold, the corresponding functional module is controlled to enter an anti-interference enhancement mode.

[0047] In an embodiment of the present application, when it is detected that the electromagnetic information exceeds the first preset threshold, the electromagnetic environment monitoring module obtains the abnormal frequency band information, and determines the corresponding functional module based on the abnormal frequency band information, and transmits the abnormal frequency band information to the corresponding functional module through the controller local area network, so that the functional module enters the anti-interference enhancement mode. It is worth noting that different functional modules can be associated with corresponding abnormal frequency band information ranges, such as the first abnormal frequency band range corresponding to the navigation module, the second abnormal frequency band range corresponding to the radio functional module, the third abnormal frequency band range corresponding to the radio functional module, the fourth abnormal frequency band range corresponding to the keyless unlocking functional module, etc. In this way, the relevant functional modules are determined based on the abnormal frequency band information, that is, the functional modules that may be affected by electromagnetic noise are determined. For example, when the abnormal frequency band information is navigation abnormal frequency band information, the functional module corresponds to the navigation functional module.

[0048] Furthermore, when the functional module enters the anti-interference enhancement mode, the strength of the signals received and sent by the vehicle antenna and the corresponding functional module can be enhanced, thereby improving the functional module's ability to resist electromagnetic noise interference.

[0049] It is worth noting that when the electromagnetic information detected is less than the first preset threshold, the electromagnetic environment monitoring module does not perform any operation or control, that is, it does not perform any operation or control on the relevant functional modules, that is, the relevant modules do not enter the anti-interference enhancement mode.

[0050] In step 240, when it is detected that the electromagnetic information exceeds the first preset threshold, the abnormal situation is announced by voice to remind the user that the electromagnetic abnormal situation is currently in place, and / or the electromagnetic abnormal situation is displayed on the vehicle display screen, prompting safe driving.

[0051] In an embodiment of the present application, a reminder is given to the user through voice playback or a vehicle-mounted display screen to warn the user that the current vehicle is in an electromagnetic abnormality condition, thereby serving as a reminder to the user to improve the user experience.

[0052] It is worth noting that when the electromagnetic signal returns to below the first preset threshold, the electromagnetic environment monitoring module controls the relevant functional modules to exit the anti-interference enhancement mode and stops reminding the user through voice playback or the vehicle display screen.

[0053] In step 250 , when it is detected that the electromagnetic information exceeds a second preset threshold, the tire pressure monitoring function module and the navigation function module are controlled to enter an anti-interference enhancement mode.

[0054] Among them, the second preset threshold is greater than the first preset threshold, and the second preset threshold indicates the maximum critical value of electromagnetic noise that the tire pressure monitoring function module and the navigation function module can withstand. When the electromagnetic information exceeds the second preset threshold, the tire pressure monitoring function module may not be able to normally monitor the tire pressure of the vehicle, and the navigation function module may not be able to provide navigation function.

[0055] Likewise, the second preset threshold may include multiple specific values, each of which corresponds to a maximum critical value of electromagnetic noise that the tire pressure monitoring function module or the navigation function module can withstand.

[0056] When the electromagnetic environment monitoring module detects that the electromagnetic information exceeds the second preset threshold, the tire pressure monitoring function module and the navigation function module enter the anti-interference enhancement mode. The tire pressure monitoring function module and the navigation function module can enhance the anti-electromagnetic interference capability of the function module by adjusting the module signal strength, or by enhancing the strength of the vehicle antenna and the function module receiving and sending signals to enhance the anti-electromagnetic interference capability of the function module.

[0057] In step 260 , when the ignition shutdown command is received, electromagnetic information outside the vehicle is acquired.

[0058] In an embodiment of the present application, when a shutdown command is received, the vehicle system responds to the shutdown command, and the vehicle transitions from a running state to a shutdown state. The number of electronic components working inside is relatively reduced, and only a small number of systems that require long-term power supply are in working condition, such as anti-theft modules and modules with memory functions. At this time, the electromagnetic noise inside the vehicle is relatively small and is not enough to affect the operation of some modules. However, when the electromagnetic noise outside the vehicle reaches a certain level, it can still affect the normal operation of related modules, such as the vehicle's keyless function module cannot be unlocked, resulting in the vehicle being unable to unlock.

[0059] In step 270 , a reminder message is sent to the backend based on the telematics processing.

[0060] In an embodiment of the present application, the electromagnetic environment monitoring module controls the electromagnetic environment collection sensor to collect electromagnetic information outside the vehicle. When the collected electromagnetic information outside the vehicle exceeds a first preset threshold, it indicates to the keyless function module that it may be interfered with by electromagnetic noise and cannot perform normal vehicle unlocking and unlocking functions. A reminder message is sent to the backend via the telematics processor (Controller Area Network, CAN) indicating that the keyless function module may be interfered with by electromagnetic noise and cannot respond normally to instructions.

[0061] The triggering conditions of the functional module state when the power source is in working state or receives a brake command are shown in Table 1:

[0062] Table 1

[0063]

[0064] In step 280 , the telematics processor obtains the current time and the geographic location of the vehicle and stores them.

[0065] In an embodiment of the present application, when a shutdown command is received and the electromagnetic information exceeds a first preset threshold, the telematics processor obtains the time when the electromagnetic anomaly occurs and the current geographic location information of the vehicle for the user to subsequently call up the system for query.

[0066] From the above, it can be seen that when the power source is in working state, the electromagnetic environment acquisition sensor collects at least one electromagnetic information from the outside or inside of the vehicle. When any one of the electromagnetic information outside the vehicle or the electromagnetic information inside the vehicle exceeds a first preset threshold, the electromagnetic environment monitoring module obtains abnormal frequency band information, and determines the relevant functional modules based on the abnormal frequency band information, and transmits the abnormal frequency band information to the relevant functional modules through the controller local area network to control the relevant functional modules to enter the anti-interference enhancement mode; in order to further reduce the influence of electromagnetic noise on the tire pressure monitoring functional module and the navigation functional module, when the electromagnetic information outside the vehicle or the electromagnetic information inside the vehicle exceeds a first preset threshold, the electromagnetic environment monitoring module obtains abnormal frequency band information, and determines the relevant functional modules based on the abnormal frequency band information, and transmits the abnormal frequency band information to the relevant functional modules through the controller local area network to control the relevant functional modules to enter the anti-interference enhancement mode. When any one of the information exceeds the second preset threshold, the electromagnetic environment monitoring module obtains the abnormal frequency band information corresponding to the tire pressure monitoring function module and the abnormal frequency band information corresponding to the navigation function module, and transmits the abnormal frequency band information to the tire pressure monitoring function module and the navigation function module, and controls the tire pressure monitoring function module and the navigation function module to enter the anti-interference enhancement mode; and when receiving the braking command, the electromagnetic environment monitoring module controls the electromagnetic environment acquisition sensor to collect electromagnetic information outside the vehicle. When the collected electromagnetic information exceeds the first preset threshold, the keyless function module is controlled to enter the anti-interference enhancement mode to reduce the situation where the user cannot unlock the vehicle.

The meanings of the terms herein are the same as those in the above vehicle electromagnetic state detection method. For specific implementation details, please refer to the description in the method embodiment.

[0068] See also Figure 4 , Figure 4 This is a structural diagram of a vehicle electromagnetic state detection device provided in an embodiment of the present application, wherein the information processing device may include an acquisition module 301, a detection module 302, a matching module 303 and an execution module 304, etc.

[0081] The matching module 303 is configured to determine the functional module corresponding to the abnormal frequency band information.

[0084] The enhancement module is used to enhance the strength of the signals received and sent by the vehicle antenna and functional modules.

[0085] The specific implementation of each of the above units can be found in the previous embodiments and will not be described again here.

[0086] As can be seen from the above, in this embodiment of the application, acquisition module 301 acquires electromagnetic information from the exterior or interior of the vehicle.

When the electromagnetic information exceeds the first preset threshold, abnormal frequency band information is acquired. Matching module 303 determines the corresponding functional module based on the abnormal frequency band information, and execution module 304 controls the corresponding functional module to enter enhanced anti-interference mode. This enables real-time detection of the electromagnetic environment of the vehicle after leaving the factory, and takes relevant measures for the corresponding functional module to reduce the possibility that the functional module is affected by electromagnetic noise and cannot perform its corresponding function.
