Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically, to a method and apparatus for vehicle signal safety management. Background Technology

[0002] With the rapid development of automotive technology, more and more cars are equipped with various communication devices, such as 4G / 5G communication modules, GPS modules, and even smart mobile devices. These communication modules transmit the vehicle's operating data to the outside world. However, in some scenarios, users do not want this type of transmission of vehicle operating data due to privacy concerns. Existing technologies already include some vehicle signal jamming devices; however, these devices can only be kept on continuously, meaning they emit a jamming signal once activated. This forces users to manually turn them on and off, which is cumbersome. Moreover, while the vehicle is running, activating the jamming signal may also affect driving safety. Summary of the Invention

[0003] To address the technical problems existing in the background art, the present invention provides a vehicle signal safety management method and device.

[0005] Obtain the vehicle's destination and its attribute data, and determine whether the attribute data meets privacy requirements;

[0006] When the attribute data meets the privacy conditions, the vehicle's driving data is acquired and recorded, and the identifiability of the driving destination is evaluated based on the recorded driving data;

[0007] When the identifiability is above a threshold, the vehicle signal shielding device is activated.

[0008] Optionally, the vehicle signal shielding device is configured to transmit multi-band combined coverage signals.

[0009] Optionally, the vehicle signal shielding device is installed inside the vehicle or on the vehicle chassis.

[0010] Optionally, determining whether the attribute data meets privacy conditions includes:

[0011] Determine whether privacy settings data can be parsed from the attribute data;

[0012] If so, then determine whether the attribute data meets the privacy conditions based on the privacy settings data;

[0013] If not, then obtain historical driving data associated with the driving destination, and determine whether the attribute data meets the privacy conditions based on the historical driving data.

[0014] Optionally, in determining whether privacy setting data can be parsed from the attribute data, the method further includes:

[0015] The attribute data is compared with the privacy scenario database. If the comparison is successful, the attribute data is determined to meet the privacy conditions. Otherwise, it is determined whether privacy setting data can be parsed from the attribute data.

[0016] Optionally, determining whether the attribute data meets privacy requirements based on the historical driving data includes:

[0017] Several historical route data and associated manual activation data of the vehicle signal jamming device are obtained by parsing the historical driving data.

[0018] A first privacy assessment value is obtained by statistically calculating the manually enabled data;

[0019] Determine the distance between the manually activated data and the recorded location in the historical route data and the destination, and derive an evaluation coefficient based on each distance;

[0020] A second privacy assessment value is derived based on the assessment coefficient and the first privacy assessment value. If the second privacy assessment value is higher than the first threshold, the attribute data is determined to meet the privacy conditions; otherwise, the attribute data is determined not to meet the privacy conditions.

[0021] Optionally, assessing the identifiability of the destination based on the recorded driving data includes:

[0022] The actual driving route is obtained by fitting the recorded driving data, and the actual driving route is input into the destination prediction model. The destination prediction model outputs the identifiable value of the driving destination corresponding to the actual driving route and each of the historical route data.

[0023] If any of the identifiable values ​​is higher than the second threshold, it is determined that the identifiability of the current destination is higher than the threshold; otherwise, it is determined that the identifiability of the current destination is not higher than the threshold.

[0024] A second aspect of the present invention provides a vehicle signal safety control device, comprising a processing module, a storage module, a communication module, and a multi-band combined coverage signal generation module. The processing module is connected to the storage module, the communication module, and the multi-band combined coverage signal generation module, respectively. The communication module is connected to the vehicle terminal.

[0025] The storage module is used to store executable computer program code;

[0026] The communication module is used to obtain the vehicle's destination and its attribute data from the vehicle terminal and transmit them to the processing module.

[0027] The processing module is configured to execute the method described in any of the preceding methods by calling the executable computer program code in the storage module, so as to control the multi-band combined coverage signal generation module to release the shielding signal in a timely manner.

[0028] A third aspect of the present invention provides an electronic device comprising: a memory storing executable program code; a processor coupled to the memory; the processor invoking the executable program code stored in the memory to perform the method as described in any of the preceding claims.

[0030] The beneficial effects of this invention are as follows:

[0031] Compared to existing technologies that continuously release the shielding signal after activation, the solution of this invention allows for on-demand and timely release of the shielding signal. Specifically, the vehicle's destination is obtained before or during driving, which can be obtained through a navigation device. Then, based on the destination's attribute data, it is determined whether the occupants of the vehicle have privacy needs at that destination. If so, further judgment is made based on the recorded driving data to determine whether the conditions for activating the shielding signal are met. If so, the vehicle's signal shielding device is activated to release the shielding signal. In this way, various signals of the vehicle will not be transmitted externally, thereby achieving effective signal shielding. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0041] like Figure 1 As shown in the figure, an embodiment of the present invention discloses a vehicle signal safety management method, including the following steps:

[0042] Obtain the vehicle's destination and its attribute data, and determine whether the attribute data meets privacy requirements;

[0043] When the attribute data meets the privacy conditions, the vehicle's driving data is acquired and recorded, and the identifiability of the driving destination is evaluated based on the recorded driving data;

[0044] When the identifiability is above a threshold, the vehicle signal shielding device is activated.

[0045] Compared to existing technologies that continuously release the shielding signal after activation, the solution of this invention allows for on-demand and timely release of the shielding signal. Specifically, the vehicle's destination is obtained before or during driving, which can be obtained through a navigation device. Then, based on the destination's attribute data, it is determined whether the occupants of the vehicle have privacy needs at that destination. If so, further judgment is made based on the recorded driving data to determine whether the conditions for activating the shielding signal are met. If so, the vehicle's signal shielding device is activated to release the shielding signal. In this way, various signals of the vehicle will not be transmitted externally, thereby achieving effective signal shielding.

[0046] The circuit structure and signal shielding principle of a vehicle signal shielding device for releasing shielded signals are generally known, and will not be elaborated upon here. Furthermore, the coverage area of ​​the shielded signal should be limited to the vehicle's body and should not be too large to avoid interfering with the signals of surrounding vehicles or roadside equipment.

[0047] Optionally, the vehicle signal shielding device is configured to transmit multi-band combined coverage signals.

[0048] In this embodiment of the invention, the vehicle is equipped with GPS and communication devices, which in turn transmit GPS signals and mobile communication signals such as 2G / 3G / 4G / 5G. In response, the vehicle signal jamming device in this invention is configured to transmit multi-band combined coverage signals, thereby suppressing and interfering with these signals. Of course, the signal bands included in the coverage signal can be freely selected and set by the occupants; this invention does not impose excessive limitations on this.

[0049] Optionally, the vehicle signal shielding device is installed inside the vehicle or on the vehicle chassis.

[0050] In this embodiment of the invention, the vehicle signal jamming device can be installed either inside a vehicle or on the vehicle chassis. When installed inside a vehicle, it can connect to the vehicle's interface, thus obtaining power from the interface and directly acquiring the vehicle's destination and operating data, such as from the vehicle's navigation system. Alternatively, the vehicle signal jamming device can be placed independently in any suitable location within the vehicle, but it must have an independent power supply and preferably also include a wireless communication module. This allows it to connect with the vehicle's infotainment system or the smart mobile terminals (phones, tablets, etc.) of the occupants, thereby also acquiring the aforementioned data.

[0051] It should be noted that after the vehicle signal jamming device releases the jamming signal, it can also disconnect the jamming based on the occupant's closing signal, or it can control the vehicle signal jamming device to periodically and briefly close the jamming signal, and determine whether the vehicle is no longer at its destination based on the received vehicle driving data. If so, it controls the vehicle signal jamming device to officially close the jamming signal; otherwise, it continues to release the jamming signal.

[0052] Optionally, determining whether the attribute data meets privacy conditions includes:

[0053] Determine whether privacy settings data can be parsed from the attribute data;

[0054] If so, then determine whether the attribute data meets the privacy conditions based on the privacy settings data;

[0055] If not, then obtain historical driving data associated with the driving destination, and determine whether the attribute data meets the privacy conditions based on the historical driving data.

[0056] In this embodiment of the invention, in addition to setting the destination before or during the trip, passengers can also add information such as notes or special options. This information includes the passenger's privacy requirements regarding the destination. For example, the "notes" may include "Note: Protect destination privacy" or the special option may be "Enable destination privacy protection". Therefore, if the parsing results of the attribute data contain such content, it can be determined that the passenger has privacy requirements, and the attribute data can be directly determined to meet the privacy conditions.

[0057] However, due to version or feature configuration issues with navigation software or in-vehicle infotainment systems, not all cars support occupants adding the aforementioned annotations or special selections to their attribute data. In such cases, it is necessary to indirectly determine whether the current destination has privacy-related requirements based on historical driving data associated with it. The specific implementation method will be explained in detail later.

[0058] Optionally, in determining whether privacy setting data can be parsed from the attribute data, the method further includes:

[0059] The attribute data is compared with the privacy scenario database. If the comparison is successful, the attribute data is determined to meet the privacy conditions. Otherwise, it is determined whether privacy setting data can be parsed from the attribute data.

[0060] In this embodiment of the invention, certain special scenarios prohibit vehicles from sending any communication data. If the destination is one of these areas, the attribute data of the destination can be compared with the scenario elements in a preset privacy scenario database. If the comparison is successful, it can be determined that the destination meets the privacy conditions, and the vehicle needs to turn on its signal jamming device when driving into the area. If the comparison fails, it means that it cannot be determined whether the scenario is one of the aforementioned special scenarios, and other methods are needed to determine it.

[0061] The privacy scenario database can be non-static, but dynamically updated according to a certain period. For example, it can periodically collect the external signal transmission data of cars entering various scenarios on the map. If a car maintains external signal transmission before entering a corresponding scenario and stops transmitting after entering, the cumulative value is incremented by 1. By statistical calculation, the frequency of such signal operation behavior by cars in the corresponding scenario can be obtained. When the frequency is higher than a certain value, the scenario can be determined as a special scenario that requires signal blocking, and thus added to the privacy scenario database. Similarly, if the frequency of such behavior for certain scenarios in the privacy scenario database falls below a certain value in a new period, the scenario can be determined as a special scenario that no longer requires signal blocking, and thus removed from the privacy scenario database.

[0062] Optionally, determining whether the attribute data meets privacy requirements based on the historical driving data includes:

[0063] Several historical route data and associated manual activation data of the vehicle signal jamming device are obtained by parsing the historical driving data.

[0064] A first privacy assessment value is obtained by statistically calculating the manually enabled data;

[0065] Determine the distance between the manually activated data and the recorded location in the historical route data and the destination, and derive an evaluation coefficient based on each distance;

[0066] A second privacy assessment value is derived based on the assessment coefficient and the first privacy assessment value. If the second privacy assessment value is higher than the first threshold, the attribute data is determined to meet the privacy conditions; otherwise, the attribute data is determined not to meet the privacy conditions.

[0067] In this embodiment of the invention, historical routes containing the current destination are retrieved from historical driving data, along with data showing that occupants manually activated the vehicle's signal jamming device along these historical routes. First, statistical calculations are performed on this manually activated data to obtain a first privacy assessment value; the more records of manually activated data, the higher the first privacy assessment value. Then, the distance between the location where the manually activated data occurred on the historical route and the current destination is calculated. Based on this distance, an assessment coefficient is derived to correct the first privacy assessment value, ultimately resulting in a second privacy assessment value with higher confidence. When the second privacy assessment value is higher than a first threshold, it can be determined that the current destination is a location where the occupants of the vehicle have a genuine privacy need, and the vehicle's signal jamming device needs to be activated.

[0068] The evaluation coefficient is derived based on each of the distances, including: performing an equivalent operation on each of the distances to obtain an equivalent distance, and calculating the evaluation coefficient based on the equivalent distance.

[0069] The equivalent distance can be obtained by averaging or weighted averaging the distances corresponding to each historical route. A larger equivalent distance, meaning the occupant activates the vehicle's shielding device earlier and further away, indicates a higher probability that the occupant intends to shield the travel route, but a lower probability that the destination is a privacy-critical location. Therefore, a smaller evaluation coefficient should be set. Conversely, a smaller equivalent distance, meaning the occupant activates the shielding device later and closer away, indicates a lower probability that the occupant intends to shield the travel route, but a higher probability that the destination is a privacy-critical location. Therefore, a larger evaluation coefficient should be set. In other words, the evaluation coefficient is roughly inversely proportional to the equivalent distance.

[0070] Optionally, assessing the identifiability of the destination based on the recorded driving data includes:

[0071] The actual driving route is obtained by fitting the recorded driving data, and the actual driving route is input into the destination prediction model. The destination prediction model outputs the identifiable value of the driving destination corresponding to the actual driving route and each of the historical route data.

[0072] If any of the identifiable values ​​is higher than the second threshold, it is determined that the identifiability of the current destination is higher than the threshold; otherwise, it is determined that the identifiability of the current destination is not higher than the threshold.

[0073] In this embodiment of the invention, the vehicle's location data can be recorded during driving to fit the vehicle's actual driving path. When other entities need to predict the vehicle's destination based on these publicly available actual driving paths, or when the vehicle's occupants have destination privacy requirements, the system can promptly determine that the identifiability of this trip is high enough. At this point, the system can control the vehicle's signal jamming device to release the jamming signal, thus preventing other entities from obtaining sufficient location data and predicting the vehicle's destination.

[0074] The destination prediction model can be trained using existing methods. Generally, a training set can be constructed by extracting local historical trajectory data from the complete historical trajectory data. This training set can then be used to train the destination prediction model to a certain extent until the destination prediction results meet the requirements. The specific process will not be elaborated further.

The processing module is connected to the storage module, the communication module, and the multi-band combined coverage signal generation module, respectively.

[0076] The storage module is used to store executable computer program code;
