Description

A method for preventing tire theft, electronic equipment, and storage medium Technical Field

[0001] This application relates to the field of hybrid power control technology, and more specifically, to a tire anti-theft method, electronic device, and storage medium in the field of hybrid power control technology. Background Technology

[0002] With the continuous growth of car ownership, car tires, as a core load-bearing component for vehicle operation, are facing increasing risks of theft and the need for theft prevention. Tires, especially original equipment tires for high-end models and special vehicles, have become prime targets for theft gangs due to their high market value.

[0003] Currently, car tire theft prevention mainly relies on mechanical locks, torque sensor alarms, or simple triggering mechanisms based on vibration sensors. Existing solutions lack effective tracking methods after tires are stolen, making it impossible to recover losses. Summary of the Invention

[0004] This application provides a method, electronic device, and storage medium for tire anti-theft. The method can coordinate with surrounding vehicles of the vehicle with the stolen tire to achieve real-time location and tracking of the stolen tire, helping users to actively recover the stolen tire and greatly enhancing the value of the anti-theft system.

[0005] In a first aspect, a method for preventing tire theft is provided, the method comprising: upon determining that a tire of a target vehicle has been stolen, obtaining the identification mark of the stolen tire and a first location of the target vehicle; based on the first location, determining a first auxiliary vehicle within a first target range centered on the target vehicle; the first auxiliary vehicle being a vehicle that allows the target vehicle to track the stolen tire; and based on the first auxiliary vehicle and the identification mark, tracking the stolen tire of the target vehicle.

[0006] In the above technical solution, when it is determined that the tires of the target vehicle have been stolen, the identification of the stolen tires and the location information of the stolen vehicle are determined. The first location is the location information of the target vehicle when the tires were stolen. Based on this, the first auxiliary vehicle within the first target range centered on the target vehicle is determined. The first auxiliary vehicle is other vehicles around the vehicle whose tires were stolen and are within the movement trajectory range of the stolen tires. Combined with the identification of the stolen tires, the real-time positioning and tracking of the stolen tires can be realized, which can help users actively recover the stolen tires based on tracking, greatly enhancing the value of the anti-theft system.

[0007] In conjunction with the first aspect, in some possible implementations, tracking stolen tires of a target vehicle based on a first auxiliary vehicle and its identification marks includes: scanning the identification marks of tires of vehicles around the first auxiliary vehicle to obtain a set of identification marks; if the identification marks in the set of identification marks include the identification mark of the stolen tire, determining a second location of the stolen tire based on the first auxiliary vehicle; and tracking the stolen tire based on the second location.

[0008] In the above technical solution, based on the identification marks of the wheels and tires around the first auxiliary vehicle, it can be compared with the identification marks of the stolen tires to determine whether the stolen tires are around the first auxiliary vehicle, thus determining the location of the stolen tires and enabling the tracking of the stolen tires. This helps users find the stolen tires and improves the value of the anti-theft system.

[0009] In combination with the first aspect and the above implementation methods, in some possible implementation methods, tracking the stolen tire based on the second location includes: determining a second auxiliary vehicle within a second target range centered on the stolen tire based on the second location; the second auxiliary vehicle is a vehicle that allows the auxiliary target vehicle to track the stolen tire; and continuously tracking the stolen tire based on the second auxiliary vehicle and its identification.

[0010] In the above technical solution, after determining the second location of the stolen tire, the tracking range is updated based on the second location, and a second auxiliary vehicle is determined to take over from the first auxiliary vehicle. This enables continuous tracking of the stolen tire, ensuring that the user can recover the stolen tire later, and further improving the effectiveness of vehicle anti-theft.

[0011] Combining the first aspect and the above implementation methods, in some possible implementation methods, the theft of the target vehicle's tires is determined by the following methods: based on the tire pressure detection sensor of the target vehicle, it is detected whether the target vehicle has triggered a level 1 alarm; based on the inertial measurement unit of the target vehicle, it is detected whether the target vehicle has triggered a level 2 alarm; based on the wheel speed of the target vehicle, it is detected whether the target vehicle has triggered a level 3 alarm; if all three alarms are triggered, the theft of the target vehicle's tires is determined.

[0012] In the above technical solution, data from multiple sensors, including tire pressure sensors, inertial measurement units, and wheel speed sensors, can detect whether the tires of a target vehicle are at risk of being stolen from multiple dimensions. When all three levels of alarms are triggered, it is determined that the tires of the target vehicle are at risk of being stolen from multiple dimensions, and the tires of the target vehicle are confirmed to have been stolen. Through multiple composite criteria, the false alarm rate of tire theft is greatly reduced, and accurate judgment of theft behavior is achieved.

[0013] Combining the first aspect and the above implementation methods, in some possible implementation methods, based on the tire pressure detection sensor of the target vehicle, detecting whether the target vehicle has triggered a level one alarm includes: detecting the wireless signal strength between the tire pressure detection sensor in each tire of the target vehicle and the vehicle body receiver; if the change in the wireless signal strength corresponding to at least one tire of the target vehicle within a preset time period is greater than a preset change amount, then it is determined that the target vehicle has triggered a level one alarm.

[0014] In the above technical solution, the change in the wireless signal strength between the tire pressure sensor and the vehicle receiver within a preset time period is greater than a preset change amount, which indicates that the tire may have been removed from the target vehicle and that the target vehicle is at risk of being stolen. This solution makes good use of the fact that when the tire is not removed, the distance between the tire pressure sensor and the vehicle receiver is fixed and the wireless signal strength does not change much in a short period of time. Only when the tire is removed from the vehicle will the wireless signal strength change suddenly in a short period of time, thus achieving a simple and efficient detection of tire theft of the target vehicle and triggering a level one alarm.

[0015] In combination with the first aspect and the above implementation methods, in some possible implementation methods, based on the inertial measurement unit of the target vehicle, detecting whether the target vehicle has triggered a secondary alarm includes: based on the inertial measurement unit, determining the vehicle body attitude angle of the target vehicle and / or the distance between each wheel of the target vehicle and the ground; if there is a change in the vehicle body attitude angle, or if the distance between at least one wheel and the ground is greater than a preset distance, determining that the target vehicle has triggered a secondary alarm.

[0016] In the above technical solution, if it is determined that there is a change in the vehicle body attitude angle, or that the distance between at least one wheel and the ground is greater than a preset distance, it can be determined that the target vehicle may be lifted by a jack. At this time, the tires of the target vehicle are easy to remove, and the tires of the target vehicle are at risk of being stolen. Based on this, it can be determined that the target vehicle triggers a secondary alarm. The process of tire removal can be directly and effectively detected by using tire distance and vehicle body attitude, which improves the accuracy of tire theft detection.

[0017] Combining the first aspect and the above implementation methods, in some possible implementation methods, based on the wheel rotation speed of the target vehicle, it is detected whether the target vehicle has triggered a level three alarm, including: if at least one wheel of the target vehicle has a wheel rotation speed of zero and at least one tire has a wheel rotation speed of non-zero, it is determined that the target vehicle has triggered a level three alarm.

[0018] In the above technical solution, considering that the wheel speed will not be zero after the tire is stolen, further judging whether the tire of the target vehicle has been stolen based on the wheel speed can accurately and effectively detect the risk of tire theft based on the dimension of wheel speed, thereby improving the efficiency of tire theft prevention.

[0019] In combination with the first aspect and the above implementation methods, in some possible implementation methods, the method further includes: generating alarm information when the target vehicle triggers a secondary alarm, and alerting the user based on the alarm information that the target vehicle is at risk of tire theft.

[0020] In the above technical solution, when a vehicle triggers a level two alarm, the vehicle is usually in the process of being stolen. At this time, generating alarm information in a timely manner reminds the user, realizing early warning. The alarm is triggered in the early stage of the theft (when the vehicle body is lifted), giving the car owner and security personnel more reaction time and improving the timeliness and effectiveness of tire anti-theft.

[0021] Secondly, a tire anti-theft device is provided, comprising: an acquisition module for acquiring the identification of the stolen tire and a first location of the target vehicle when it is determined that the tire of the target vehicle has been stolen; a determination module for determining, based on the first location, a first auxiliary vehicle within a first target range centered on the target vehicle; the first auxiliary vehicle being a vehicle that allows the target vehicle to track the stolen tire; and a tracking module for tracking the stolen tire of the target vehicle based on the first auxiliary vehicle and the identification.

[0022] In conjunction with the second aspect, in some possible implementations, the tracking module is specifically used to: scan the identification marks of vehicle tires around the first auxiliary vehicle based on the first auxiliary vehicle to obtain a set of identification marks; if the identification marks in the set of identification marks include the identification mark of the stolen tire, determine the second location of the stolen tire based on the first auxiliary vehicle; and track the stolen tire based on the second location.

[0023] In combination with the second aspect and the above implementation methods, in some possible implementation methods, the tracking module is specifically used to: determine a second auxiliary vehicle within a second target range centered on the stolen tire based on the second location; the second auxiliary vehicle is a vehicle that allows the auxiliary target vehicle to track the stolen tire; and continuously track the stolen tire based on the second auxiliary vehicle and its identification.

[0024] In conjunction with the second aspect and the above implementation methods, in some possible implementation methods, the determining module is also used to: detect whether the target vehicle has triggered a level one alarm based on the tire pressure detection sensor of the target vehicle; detect whether the target vehicle has triggered a level two alarm based on the inertial measurement unit of the target vehicle; detect whether the target vehicle has triggered a level three alarm based on the wheel speed of the target vehicle; and determine that the tires of the target vehicle have been stolen if all three alarms are triggered.

[0025] Combining the second aspect and the above implementation methods, in some possible implementation methods, the determining module is specifically used to: detect the wireless signal strength between the tire pressure detection sensor in each tire of the target vehicle and the vehicle body receiver; if the change in the wireless signal strength corresponding to at least one tire of the target vehicle within a preset time period is greater than a preset change amount, then the target vehicle is determined to trigger a level one alarm.

[0026] In combination with the second aspect and the above implementation methods, in some possible implementation methods, the determining module is specifically used to: determine the vehicle body attitude angle of the target vehicle and / or the distance between each wheel of the target vehicle and the ground based on the inertial measurement unit; and determine that the target vehicle triggers a secondary alarm when there is a change in the vehicle body attitude angle, or when there is at least one wheel with a distance greater than a preset distance.

[0027] Combining the second aspect and the above implementation methods, in some possible implementation methods, the determining module is specifically used to: determine that the target vehicle triggers a level three alarm when at least one wheel of the target vehicle has a wheel speed of zero and at least one tire has a wheel speed of non-zero.

[0028] In conjunction with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the device further includes an alarm module, which generates alarm information when the target vehicle triggers a secondary alarm, and alerts the user based on the alarm information that the target vehicle is at risk of tire theft.

[0029] Thirdly, an electronic device is provided, including a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, causing the electronic device to perform the methods of the first aspect or any possible implementation thereof.

[0030] Fourthly, a computer program product is provided, comprising: computer program code, which, when run on a computer, causes the computer to perform the methods described in the first aspect or any possible implementation thereof.

[0031] Fifthly, a computer-readable storage medium is provided that stores computer program code, which, when executed on a computer, causes the computer to perform the methods described in the first aspect or any possible implementation thereof. Attached Figure Description

[0035] Figure 4 is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Detailed Implementation

[0036] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0037] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0038] With the continuous growth of car ownership, car tires, as a core load-bearing component for vehicle operation, are facing increasing risks of theft and the need for theft prevention. Tires, especially original equipment tires for high-end models and special vehicles, have become prime targets for theft gangs due to their high market value.

[0039] Currently, car tire theft prevention mainly relies on mechanical locks, torque sensor alarms, or simple triggering mechanisms based on vibration sensors. These solutions have significant shortcomings: mechanical locks offer limited protection and provide a poor user experience; single sensors (such as vibration sensors) are highly susceptible to false alarms due to external interference (such as passing vehicles or thunder); more importantly, existing solutions lack effective tracking methods after tire theft, making it impossible to recover losses.

[0040] Based on this, this application proposes a tire anti-theft method, which achieves real-time positioning and tracking of stolen tires by coordinating with vehicles around the target vehicle of the stolen tire. This can help users actively recover stolen tires and greatly enhance the value of the anti-theft system.

[0041] Figure 1 is a system schematic diagram of an example implementation of the scheme provided in this application.

[0042] It should be understood that the tire anti-theft method provided in this application embodiment can be applied to the system 100 shown in FIG1. ​​For example, as shown in FIG1, the system 100 includes: target vehicle 10, cloud platform 20 and auxiliary vehicle 30.

[0043] In this system, target vehicle 10 is the vehicle whose tires were stolen. Target vehicle 10 establishes a connection with cloud platform 20, and information can be exchanged between them. Auxiliary vehicle 30 refers to other vehicles besides the target vehicle, and may specifically include multiple vehicles. Auxiliary vehicle 30 also establishes a connection with cloud platform 20, and information can be exchanged between them.

[0044] Specifically, the target vehicle 10 and the auxiliary vehicle 30 can establish a connection with the cloud platform 20 through the vehicle-mounted T-Box (Telematics Box, vehicle-mounted communication terminal).

[0045] If the target vehicle 10 detects that its tires have been stolen, it can upload relevant information about the stolen tires to the cloud platform 20 via a T-box.

[0046] The cloud platform 20 is used to receive information about the stolen tires uploaded by the target vehicle 10, and send instructions to the auxiliary vehicle 30 to track the stolen tires based on the information about the stolen tires.

[0047] The auxiliary vehicle 30 is used to receive instructions to track stolen tires and to track stolen tires of the target vehicle 10 based on the instructions.

[0048] In some embodiments, the target vehicle 10 may upload relevant parameters for monitoring whether the tires have been stolen to the cloud platform 20. After receiving the relevant parameters, the cloud platform 20 may determine whether the tires of the target vehicle 10 have been stolen based on the relevant parameters.

[0049] The aforementioned auxiliary vehicle is a pre-set vehicle that is allowed to help the target vehicle track the stolen tires. For example, the auxiliary vehicle could be another vehicle of the same brand as the target vehicle.

[0050] Figure 2 is a schematic flowchart of a tire anti-theft method provided in an embodiment of this application. The method is applied to the system 100 shown in Figure 1.

[0051] For example, as shown in Figure 2, the method 200 includes: step 201, in the case that the tires of the target vehicle have been stolen, obtaining the identification of the stolen tires and the first location of the target vehicle; step 202, based on the first location, activating the sentry mode of a first auxiliary vehicle within a preset range centered on the target vehicle; the first auxiliary vehicle is a vehicle that allows the activation of the sentry mode to assist the target vehicle in tracking the stolen tires; step 203, based on the sentry mode and identification of the first auxiliary vehicle, tracking the stolen tires of the target vehicle.

[0052] In the embodiment shown in Figure 2, when it is determined that the tires of the target vehicle have been stolen, the identification of the stolen tires and the location information of the stolen vehicle are determined. The first location is the location information of the target vehicle when the tires were stolen. Based on this, the first auxiliary vehicle within the first target range centered on the target vehicle is determined. The first auxiliary vehicle is other vehicles around the vehicle whose tires were stolen and are within the movement trajectory range of the stolen tires. Combined with the identification of the stolen tires, the real-time positioning and tracking of the stolen tires can be realized, which can help users actively recover the stolen tires based on tracking, greatly enhancing the value of the anti-theft system.

[0053] The specific implementation of each step in the embodiment shown in Figure 2 will be described in detail below: In step 201, the target vehicle is the vehicle whose tires have been stolen. The target vehicle is equipped with a variety of sensors. After the target vehicle is parked, turned off, or even locked, the tires can be monitored in real time based on the various sensors to see if they have been stolen.

[0054] As shown in Figure 1, the target vehicle establishes a connection with the cloud platform. The target vehicle can determine whether its tires have been stolen by itself through various sensors. Once the target vehicle confirms that the tires have been stolen, it needs to upload the relevant information about the stolen tires to the cloud platform so that the cloud platform can perform subsequent tracking operations on the stolen tires.

[0055] Alternatively, the target vehicle can upload relevant parameters from various sensors to a cloud platform, which can then determine whether the vehicle's tires have been stolen based on these parameters, and subsequently track the stolen tires.

[0056] Specifically, if it is determined that the tires of the target vehicle have been stolen, and it is then determined that the target vehicle needs assistance in tracking the stolen tires, the target vehicle can upload the identification of the stolen tires and the location of the target vehicle (i.e., the first location mentioned above) to the cloud platform, so that the cloud platform can track the stolen tires based on the identification of the stolen tires and the first location.

[0057] Understandably, each tire of a vehicle is equipped with a tire pressure monitoring system (TMPS). Each TMPS has a unique identifier, denoted as TMPSID (Tire Pressure Monitoring System Identifier). The TMPS ID is typically a 32-bit (8-digit hexadecimal) electronic identification code, which is the unique hardware identification code for that sensor. The identification code of the stolen tire is uploaded to the cloud platform so that the cloud platform can determine the identity information of the stolen tire.

[0058] The primary location is the position of the target vehicle, specifically its latitude and longitude. The target vehicle may be equipped with a GPS (Global Positioning System), which allows it to determine its latitude and longitude, obtain its primary location, and upload this location to a cloud platform. This upload enables the cloud platform to pinpoint the location of the stolen tires.

[0059] In one possible implementation, the theft of a target vehicle's tires is determined by: detecting whether the target vehicle has triggered a Level 1 alarm based on its tire pressure monitoring sensor; detecting whether the target vehicle has triggered a Level 2 alarm based on its inertial measurement unit; detecting whether the target vehicle has triggered a Level 3 alarm based on its wheel rotation speed; and determining that the target vehicle's tires have been stolen if all three alarms are triggered.

[0060] As described in the above embodiment, each tire of the target vehicle is equipped with a tire pressure detection sensor. The tire pressure detection sensor is used to detect tire pressure-related data in real time and send the tire pressure-related data to the controller of the target vehicle so that the controller can grasp the tire pressure status.

[0061] Specifically, based on the tire pressure monitoring sensors in each tire of the target vehicle, it can be determined whether each tire of the target vehicle is at risk of being stolen. If it is determined that any tire of the target vehicle is at risk of being stolen, a level one alarm is triggered.

[0062] It is understandable that when any tire of a target vehicle is stolen, the data corresponding to the tire pressure monitoring sensor in the stolen tire will change. Therefore, it is possible to determine whether the vehicle's tires are at risk of being stolen based on the tire pressure monitoring sensor data, and thus determine whether the vehicle should trigger a Level 1 alarm.

[0063] The target vehicle is also equipped with an Inertial Measurement Unit (IMU), which can measure the vehicle's three-axis acceleration and three-axis angular velocity. Combined with algorithms, the vehicle's real-time attitude can be calculated, which facilitates vehicle stability control based on the measured acceleration, angular velocity, and attitude.

[0064] The three axes include the horizontal X-axis and Y-axis, and the vertical Z-axis. Specifically, the X-axis is the horizontal direction (i.e., the direction of movement), and the Y-axis is the vertical direction (perpendicular to the direction of movement).

[0065] Specifically, based on the inertial measurement unit, it can be determined whether there is a risk of tire theft on the target vehicle. If it is determined that there is a risk of tire theft on the target vehicle, a level two alarm is triggered upon detection of the target vehicle.

[0066] Understandably, when removing the tires of a target vehicle, it is usually necessary to lift the vehicle body on the side with the stolen tires. At this time, the vehicle's body posture will change. Therefore, it is possible to determine whether the vehicle's tires are at risk of being stolen based on the inertial measurement unit, and thus determine whether the vehicle triggers a level two alarm.

[0067] Each tire of the target vehicle can also be equipped with a wheel speed sensor, which can be used to detect the rotation speed of the wheel in real time and send the rotation speed data to the controller of the target vehicle so that the controller can grasp the rotation status of the wheel.

[0068] Specifically, based on the wheel speed measured by the wheel speed sensor in each tire of the target vehicle, it can be determined whether each tire of the target vehicle is at risk of being stolen. If it is determined that any tire of the target vehicle is at risk of being stolen, a level three alarm is triggered.

[0069] It is understandable that when any tire of a target vehicle is stolen, the wheel speed sensor in the stolen tire will change the wheel speed. Therefore, the risk of the vehicle's tires being stolen can be determined based on the wheel speed, and thus, whether the vehicle triggers a level 3 alarm can be determined.

[0070] By combining Level 1, Level 2, and Level 3 alarms, the risk of tire theft of a vehicle can be determined from different dimensions. If the target vehicle triggers all three alarms simultaneously, it can be determined that the target vehicle is at risk of tire theft in multiple dimensions. At this point, the risk of tire theft of the target vehicle is relatively high, and it can be determined that the tires of the target vehicle have been stolen.

[0071] The above method utilizes data from multiple sensors, including tire pressure sensors, inertial measurement units, and wheel speed sensors, to detect the risk of tire theft on a target vehicle from multiple dimensions. When all three levels of alarms (Level 1, Level 2, and Level 3) are triggered, it is determined that the target vehicle's tires are at risk of theft across multiple dimensions, thus confirming that the tires have been stolen. Through multiple composite criteria, the false alarm rate of tire theft is greatly reduced, achieving accurate judgment of theft behavior.

[0072] In one possible implementation, based on the tire pressure monitoring sensors of the target vehicle, detecting whether the target vehicle has triggered a Level 1 alarm includes: detecting the wireless signal strength between the tire pressure monitoring sensors in each tire of the target vehicle and the vehicle body receiver; if the change in the wireless signal strength corresponding to at least one tire of the target vehicle within a preset time period is greater than a preset change amount, then it is determined that the target vehicle has triggered a Level 1 alarm.

[0073] The vehicle body receiver is the receiving terminal for the radio frequency signals of the TPMS sensor. It is usually located in the vehicle chassis, trunk, or other parts of the vehicle body. The tire pressure detection sensor usually sends the measured tire pressure data to the vehicle body receiver via wireless signal. The vehicle body receiver then transmits the received tire pressure data to the TPMS controller installed in the vehicle body.

[0074] To ensure the vehicle's receiver accurately receives tire pressure data, the wireless signal strength between the receiver and the tire pressure monitoring sensor needs to be maintained above a calibrated threshold (e.g., 90%). Wireless signal strength decreases with distance. When a tire is stolen, it will be further away from the target vehicle, causing a decrease in the wireless signal strength between the receiver and the sensor. Therefore, the risk of tire theft can be detected based on the wireless signal strength between the tire pressure monitoring sensor and the receiver. If the wireless signal strength between the tire pressure monitoring sensor and the receiver indicates a risk of tire theft, a Level 1 alarm is triggered.

[0075] Specifically, the TPMS controller in the target vehicle can detect the wireless signal strength between the tire pressure monitoring sensor in each tire of the target vehicle and the vehicle body receiver in real time. If it is detected that the wireless signal strength of at least one tire of the target vehicle changes by a greater than a preset amount within a preset time period, it is determined that the tires of the target vehicle are at risk of being stolen. At this time, the target vehicle is detected and a level one alarm is triggered.

[0076] The Received Signal Strength Indicator (RSSI) can be expressed as a percentage, with 100% representing the maximum signal strength and 0% representing the minimum. The preset duration is a short, pre-calibrated period, such as 1 second, used to determine if the signal strength changes abruptly within a short time. The preset change amount is the maximum change in signal strength assuming the tire is not removed, for example, 30%.

[0077] If the wireless signal strength between the tire pressure monitoring sensor and the vehicle body receiver of at least one tire in the target vehicle changes by more than 30% within 1 second, it can be determined that the tire has been removed from the vehicle body and is at risk of being stolen. In some embodiments, the tire can also be identified as a stolen tire.

[0078] For example, the target vehicle includes wheels a, b, c, and d. Tire pressure monitoring sensor 1 is installed in the tire of wheel a, tire pressure monitoring sensor 2 is installed in the tire of wheel b, tire pressure monitoring sensor 3 is installed in the tire of wheel c, and tire pressure monitoring sensor 4 is installed in the tire of wheel d. The wireless signal strength between tire pressure monitoring sensor 1 and the vehicle body receiver is denoted as RSSI 1, the wireless signal strength between tire pressure monitoring sensor 2 and the vehicle body receiver is denoted as RSSI 2, the wireless signal strength between tire pressure monitoring sensor 3 and the vehicle body receiver is denoted as RSSI 3, and the wireless signal strength between tire pressure monitoring sensor 4 and the vehicle body receiver is denoted as RSSI 4.

[0079] Based on this, the wireless signal strength corresponding to tire a can be determined as RSSI 1, tire b as RSSI 2, tire c as RSSI 3, and tire d as RSSI 4. Assuming that within a preset time period, the change in RSSI 1 is detected to be 10%, RSSI 2 to 0%, RSSI 3 to 50%, and RSSI 4 to 0%, and the change in RSSI 3 corresponding to tire c is greater than the preset change of 30%, it can be determined that a tire on the target vehicle experiences a sudden change in wireless signal strength within a short period, indicating a risk of theft. In this case, a level one alarm is triggered upon detection of the target vehicle.

[0080] It is understandable that if multiple tires of the target vehicle are stolen at the same time, there may be a situation where the wireless signal strength of multiple tires changes suddenly in a short period of time. In this case, it can be determined that multiple tires of the target vehicle are at risk of being stolen, and the detection of the target vehicle will trigger a level one alarm.

[0081] In the above method, the risk of tire theft is determined by the change in the wireless signal strength between the tire pressure sensor and the vehicle receiver within a preset time period being greater than a preset change amount. This method effectively utilizes the fact that when the tire is not removed, the distance between the tire pressure sensor and the vehicle receiver is fixed, and the wireless signal strength does not change significantly in a short period of time. Only when the tire is removed and moved away from the vehicle will the wireless signal strength change drastically in a short period of time. This method achieves a simple and efficient detection of tire theft of the target vehicle and triggers a level one alarm.

[0082] In one possible implementation, the detection of whether the target vehicle has triggered a secondary alarm is based on the inertial measurement unit of the target vehicle, including: determining the vehicle body attitude angle and / or the distance between each wheel of the target vehicle and the ground based on the inertial measurement unit; and determining that the target vehicle has triggered a secondary alarm if there is a change in the vehicle body attitude angle or if the distance between at least one wheel and the ground is greater than a preset distance.

[0083] Vehicle attitude angles refer to a set of angular parameters describing the tilt state of a vehicle body in three-dimensional space. They typically include roll angle and pitch angle, both defined based on the vehicle coordinate system. Roll angle refers to the angle of rotation of the vehicle body around the axis (X-axis) of the vehicle's direction of travel. For example, when one tire is jacked up, the vehicle body tilts to the other side; this tilt angle is the roll angle. The body roll during cornering also falls under the category of roll angle changes. Pitch angle refers to the angle of rotation of the vehicle body around the vehicle's horizontal axis (Y-axis). For example, when the front wheels are jacked up, the front of the vehicle rises and the rear sinks; the resulting tilt angle is the pitch angle. The forward and backward tilt of the vehicle when going uphill or downhill also falls under the category of pitch angle changes.

[0084] As described in the above embodiment, the inertial measurement unit can measure the three-axis acceleration and three-axis angular velocity of the target vehicle. Combined with the algorithm, the real-time attitude of the vehicle can be calculated to obtain the vehicle body attitude angle.

[0085] If the target vehicle's body attitude angle is determined to have changed, it can be determined that the target vehicle's body may have been lifted by a jack. At this time, the target vehicle's tires are easy to remove, and the target vehicle's tires are at risk of being stolen. Based on this, it can be determined that the target vehicle has triggered a level two alarm.

[0086] Understandably, when the vehicle is stationary, the acceleration and angular velocity data measured by the inertial measurement unit are fixed values, and therefore the resulting vehicle attitude angles are also fixed values. When a tire of the target vehicle is stolen, the removal of that tire requires jacking up the corresponding part of the vehicle body before the tire can be removed. When the jack lifts the side of the vehicle body with that tire, the acceleration and angular velocity data measured by the inertial measurement unit will change. Combined with the algorithm to calculate the vehicle's real-time attitude, the resulting vehicle attitude angles will also change relative to the stationary state. Therefore, if a change in the vehicle attitude angle is confirmed, it can be determined that the target vehicle's body may have been lifted by a jack, and the target vehicle's tires are at risk of being stolen. At this point, a level two alarm is triggered for the target vehicle.

[0087] The distance between the wheel and the ground refers to the vertical distance from the center of the wheel to the ground. When the vehicle body is not lifted, the vertical distance from the center of the wheel to the ground is the tire rolling radius. The size of the tire rolling radius is usually within a certain range, and it fluctuates to some extent with changes in tire pressure and vehicle load.

[0088] When a wheel is lifted by a jack, causing the vehicle to tilt, changes in the vehicle's attitude angles (roll and pitch angles) are transmitted through vehicle geometry parameters (wheelbase and track width) to the center of the corresponding wheel, altering the vertical distance from the center to the ground. For example, when the left front wheel is lifted, the vehicle tilts to the right, and the height of the left front wheel's center rises. Based on the vehicle's attitude angles and parameters such as wheelbase and track width, the distance between each wheel of the target vehicle and the ground can be calculated.

[0089] The preset distance can be the upper boundary of the range where the tire rolling radius is located, and the preset distance can be, for example, 0.35m.

[0090] If at least one wheel of a target vehicle is raised above the ground beyond a preset distance, it can be determined that the wheel has been lifted off the ground. This indicates that the vehicle's tires are easily detachable and at risk of theft, thus triggering a level two alarm. Furthermore, the stolen tires can be identified as those of the wheels whose distance from the ground exceeds the preset distance.

[0091] It is understandable that the target vehicle may have multiple tires stolen at the same time. Therefore, it is possible that multiple wheels are detected to be at greater than the preset distance from the ground. In this case, it can be determined that multiple tires of the target vehicle are at risk of being stolen, and the detection of the target vehicle will trigger a level two alarm.

[0092] In the above method, if it is determined that there is a change in the vehicle body attitude angle, or that the distance between at least one wheel and the ground is greater than a preset distance, it can be determined that the target vehicle may be lifted by a jack. At this time, the tires of the target vehicle are easy to remove, and the tires of the target vehicle are at risk of being stolen. Based on this, it can be determined that the target vehicle triggers a secondary alarm. By using tire distance and vehicle body attitude, the process of tire removal can be directly and effectively detected, which improves the accuracy of tire theft detection.

[0093] In one possible implementation, the method further includes: generating alarm information when a secondary alarm is triggered by the target vehicle, and alerting the user based on the alarm information that the target vehicle's tires are at risk of being stolen.

[0094] If a target vehicle triggers a Level 2 alarm, it can be determined that the vehicle may be jacked up and its tires may be easily removed and stolen. In this case, the target vehicle can generate an alarm message and send it to the user device connected to the target vehicle, allowing the user to promptly understand the vehicle's abnormal status based on the alarm information.

[0095] The alarm information mentioned above may include messages indicating abnormalities in the target vehicle's condition, such as "the target vehicle's tires are at risk of being stolen" or "the vehicle body may be abnormally lifted."

[0096] The user device that establishes a connection with the target vehicle can be an electronic device such as a mobile phone, computer, or tablet. The target vehicle can establish a connection with the user device through a T-box and a cloud platform. When the target vehicle generates an alarm, it can upload the alarm information to the cloud platform via the T-box. After receiving the alarm information, the cloud platform will distribute it to the user device connected to the target vehicle. Upon receiving the alarm information, the user device can display it, allowing the user to promptly understand the abnormal status of the target vehicle.

[0097] In some embodiments, if it is determined that the target vehicle has triggered a level two alarm, the buzzer or headlights of the target vehicle can also be controlled to realize an alarm based on sound or light, alerting occupants inside the vehicle and people outside the vehicle.

[0098] In the above method, when a vehicle triggers a level two alarm, the vehicle is usually in the process of being stolen. At this time, generating alarm information in a timely manner reminds the user, realizing early warning. Triggering the alarm in the early stage of the theft (when the vehicle body is lifted) gives the car owner and security personnel more reaction time, improving the timeliness and effectiveness of tire theft prevention.

[0099] In one possible implementation, the system detects whether the target vehicle has triggered a Level 3 alarm based on the wheel rotation speed of the target vehicle; if at least one wheel of the target vehicle has a wheel rotation speed of zero and at least one wheel has a wheel rotation speed of non-zero, the system determines that the target vehicle has triggered a Level 3 alarm.

[0100] As described in the above embodiment, the target vehicle includes multiple wheels, each equipped with a speed sensor to detect the wheel speed measured by the speed sensor. If at least one wheel of the target vehicle has a wheel speed of zero, and at least one wheel has a wheel speed of non-zero, it is determined that the tires of the target vehicle are at risk of being stolen, and a level three alarm is triggered.

[0101] Understandably, in a scenario where a tire is stolen, the target vehicle is stationary, and the wheel speed is typically zero. When a tire is stolen, it will be moved on a trailer. At this point, the speed sensor in the stolen tire will measure a non-zero wheel speed, but the speed sensors in the other tires that were not removed will still measure a zero wheel speed.

[0102] When at least one tire is stolen, at least one wheel of the target vehicle will have a non-zero wheel speed. If multiple tires are stolen simultaneously (e.g., two tires are stolen at the same time), then two wheels will have non-zero wheel speeds, and two wheels will have zero wheel speeds. Therefore, if at least one wheel of the target vehicle has a zero wheel speed, and at least one wheel has a non-zero wheel speed, it is determined that the target vehicle is at risk of tire theft, and a Level 3 alarm is triggered.

[0103] In some embodiments, the tires of wheels whose rotational speed is not zero can also be identified as stolen tires.

[0104] For example, the target vehicle includes wheels a, b, c, and d. The wheel speeds of wheel a are recorded as n1, wheel b as n2, wheel c as n3, and wheel d as n4. Assume the currently recorded wheel speeds of wheel a are n1 = 0 rpm, wheel b as n2 = 0 rpm, wheel c as n3 = 5 rpm, and wheel d as n4 = 10 rpm. At this point, it is determined that the target vehicle has two wheels (wheel a and wheel b) with zero wheel speeds and two wheels (wheel c and wheel d) with non-zero wheel speeds. This satisfies the condition that at least one wheel has a zero wheel speed and at least one wheel has a non-zero wheel speed. Therefore, it is determined that the tires of wheel c and wheel d are at risk of being stolen, and a level three alarm is triggered on the target vehicle.

[0105] The above method takes into account the characteristic that the wheel speed will not be zero after the tire is stolen. Judging whether the tire of the target vehicle has been stolen based on the wheel speed can accurately and effectively detect the risk of tire theft based on the wheel speed dimension, thus improving the efficiency of tire theft prevention.

[0106] In step 202, the first location is the current location of the target vehicle, i.e. the location where the theft occurred. The target vehicle can upload the first location to the cloud platform when it detects that the tire has been stolen. After obtaining the first location, the cloud platform divides the electronic fence based on the first location to obtain the first target range, which is the range within the electronic fence.

[0107] Specifically, after obtaining the first location, the cloud platform can draw a circle with the first location as the center and a preset distance as the radius to obtain an electronic fence, that is, to obtain the first target range. The vehicle within the first target range that allows the auxiliary target vehicle to track the stolen tire is identified as the first auxiliary vehicle.

[0108] For example, if the first position is (x, y) and the preset distance is 1 kilometer, the cloud platform will identify the vehicle within the first fence that allows the auxiliary target vehicle to track the stolen tire as the first auxiliary vehicle.

[0109] In step 203, after the first auxiliary vehicle is identified, the cloud platform can issue a tracking instruction to the first auxiliary vehicle to track the stolen tires, so that the first auxiliary vehicle can track the stolen tires of the target vehicle based on the tracking instruction.

[0110] Specifically, the cloud platform can send a tracking instruction to the first auxiliary vehicle to track the stolen tire, which may include the identification of the stolen tire. After obtaining the identification of the stolen tire, the first auxiliary vehicle can detect whether there is a stolen tire in the surrounding area based on the identification of the stolen tire, so as to track the stolen tire.

[0111] In some embodiments, the first auxiliary vehicle may currently be in a parked, off-engine state. In this case, the entire first auxiliary vehicle is powered down and cannot detect the presence of stolen tires nearby. The instructions sent by the cloud platform to track stolen tires may also include an instruction to activate sentry mode. When the first auxiliary vehicle is in a parked, off-engine state, upon receiving the instruction from the cloud platform to activate sentry mode, it will activate its own sentry mode. In sentry mode, some modules of the first auxiliary vehicle are powered on and can detect the presence of stolen tires nearby. At this time, the first auxiliary vehicle tracks the stolen tires based on sentry mode.

[0112] In one possible implementation, tracking stolen tires of a target vehicle based on a first auxiliary vehicle and its identification marks includes: scanning the identification marks of tires of vehicles around the first auxiliary vehicle to obtain a set of identification marks; if the identification marks in the set of identification marks include the identification mark of the stolen tire, determining a second location of the stolen tire based on the first auxiliary vehicle; and tracking the stolen tire based on the second location.

[0113] After receiving the instruction to track the stolen tire, the first auxiliary vehicle scans the identification tags of all vehicle tires in the vicinity, obtaining a set of identification tags. Then, it compares each identification tag in the set with the identification tag of the stolen tire to determine whether the set contains the identification tag of the stolen tire.

[0114] Specifically, when the first auxiliary vehicle approaches the vehicle carrying the stolen tire, it enters the TPMS signal coverage area of ​​the stolen tire (typically within 10-50 meters). The body receiver of the first auxiliary vehicle captures the broadcast data packet, and the TPMS controller can extract the identification of the stolen tire by parsing the data packet.

[0115] If a claim is related to an identity that matches the identity of the stolen tire in the identity set, and the identity set includes the identity of the stolen tire, then it is determined that the stolen tire has been tracked.

[0116] In some embodiments, after it is determined that the stolen tire has been tracked, the current location of the stolen tire can be determined based on the first auxiliary vehicle to obtain a second location; then the second location is sent to the target vehicle so that the target vehicle can determine the current location of the stolen tire and enable the owner of the target vehicle to retrieve the stolen tire based on the current location of the stolen tire.

[0117] Specifically, there can be multiple first auxiliary vehicles. When there are multiple first auxiliary vehicles, for each first auxiliary vehicle, the identification marks of the tires of surrounding vehicles scanned by itself are organized to obtain a set of identification marks corresponding to the first auxiliary vehicle. Multiple first auxiliary vehicles will thus have multiple sets of identification marks. It is then determined whether the identification mark set corresponding to each first auxiliary vehicle includes the identification mark of the stolen tire. The first auxiliary vehicle corresponding to the set of identification marks of the stolen tire is identified, and the current location of that first auxiliary vehicle is determined as the current location of the stolen tire.

[0118] For example, the first auxiliary vehicle includes: vehicle 31, vehicle 32, and vehicle 33. The set of identifiers scanned by vehicle 31 is set E, the set of identifiers scanned by vehicle 32 is set F, and the set of identifiers scanned by vehicle 33 is set G. Set G includes the identifier of the stolen tire. At this time, vehicle 33 obtains its current location and uploads it as the current location of the stolen tire to the cloud platform. The cloud platform then sends the current location of the stolen tire to the target vehicle to achieve tracking of the stolen tire.

[0119] In the above method, based on the identification marks of the wheels and tires around the first auxiliary vehicle, the identification marks of the stolen tires can be compared with those of the stolen tires to determine whether the stolen tires are around the first auxiliary vehicle, thus determining the location of the stolen tires and enabling the tracking of the stolen tires. This helps users recover stolen tires and increases the value of the anti-theft system.

[0120] In one possible implementation, tracking a stolen tire based on a second location includes: determining a second auxiliary vehicle within a second target range centered on the stolen tire based on the second location; the second auxiliary vehicle being a vehicle that allows the target vehicle to track the stolen tire; and continuously tracking the stolen tire based on the second auxiliary vehicle and its identification.

[0121] As described in the above embodiment, the current location of the stolen tire can be determined based on the current location of the first auxiliary vehicle that has scanned the identity information of the stolen tire, thus obtaining a second location. After obtaining the second location, the electronic fence is redefined based on the second location to obtain a second target range, which is the range within the redefined electronic fence.

[0122] Specifically, after obtaining the second location, the cloud platform can redraw a circle with the second location as the center and a preset distance as the radius to obtain the electronic fence, that is, to obtain the second target range. The vehicles within the second target range that are allowed to assist the target vehicle in tracking the stolen tires are identified as the second auxiliary vehicles.

[0123] Once the second auxiliary vehicle is identified, the cloud platform can issue a command to the second auxiliary vehicle to track the stolen tires, enabling the second auxiliary vehicle to track the stolen tires of the target vehicle based on the command.

[0124] Specifically, the cloud platform can send a tracking instruction to the second auxiliary vehicle to track stolen tires, which may include the identification of the stolen tires. After obtaining the identification of the stolen tires, the second auxiliary vehicle can detect whether there are any stolen tires in the surrounding area based on the identification of the stolen tires, so as to track the stolen tires.

[0125] It is understandable that the stolen tire may be in continuous motion, and at times, it may move beyond the first target range. In such cases, the first auxiliary vehicle within the first target range will be unable to track the stolen tire. Therefore, the geofence can be updated based on the location of the stolen tire to obtain a second target range. The second auxiliary vehicle within the second target range can then take over from the first auxiliary vehicle to achieve continuous tracking of the stolen tire.

[0126] In some embodiments, the second auxiliary vehicle may also be in a parked, off-engine state. In this case, the entire second auxiliary vehicle is powered down and cannot detect the presence of stolen tires. The instructions sent by the cloud platform to track stolen tires may also include an instruction to activate sentry mode. When the second auxiliary vehicle is in a parked, off-engine state, upon receiving the instruction from the cloud platform to activate sentry mode, it will activate its own sentry mode. In sentry mode, some modules of the second auxiliary vehicle are powered on and can detect the presence of stolen tires. At this time, the second auxiliary vehicle continuously tracks the stolen tires based on sentry mode.

[0127] After the second auxiliary vehicle tracks the stolen tire, the current location of the stolen tire can be re-determined based on the second auxiliary vehicle to obtain a third location. As in the above embodiment, the current location of the stolen tire is determined based on the first auxiliary vehicle, and the location of the second auxiliary vehicle that detected the identification of the stolen tire can be used as the current location of the stolen tire to obtain a third location.

[0128] Once the third location is obtained, it can be sent to the target vehicle so that the vehicle owner can retrieve the stolen tires based on the third location.

[0129] In some embodiments, the electronic fence can be redefined based on the third location, and a third auxiliary vehicle can be identified so that the third auxiliary vehicle takes over from the second auxiliary vehicle to continue tracking the stolen tire, and so on, until the location of the stolen tire no longer changes.

[0130] In some embodiments, the movement trajectory of the stolen tires can be determined based on the previously tracked locations of the stolen tires, and the police can be notified to conduct precise interception based on the movement trajectory of the stolen tires, so as to recover the stolen tires.

[0131] In some embodiments, after the first and second auxiliary vehicles scan the identification of the stolen tires, they can also collect the characteristics of the vehicle carrying the stolen tires based on the camera, including the image of the vehicle, license plate and other data, and upload the characteristics of the vehicle and the location of the stolen tires to the cloud platform so that the cloud platform can help the target vehicle find the stolen tires based on the above data.

[0132] In the above method, after determining the second location of the stolen tire, the tracking range is updated based on the second location, and a second auxiliary vehicle is determined to take over from the first auxiliary vehicle. This enables continuous tracking of the stolen tire, ensuring that the user can recover the stolen tire later, and further improving the effectiveness of vehicle anti-theft.

[0137] In one possible implementation, the determining module 302 is further configured to: detect whether the target vehicle has triggered a level one alarm based on the tire pressure detection sensor of the target vehicle; detect whether the target vehicle has triggered a level two alarm based on the inertial measurement unit of the target vehicle; detect whether the target vehicle has triggered a level three alarm based on the wheel rotation speed of the target vehicle; and determine that the tires of the target vehicle have been stolen if all three alarms are triggered.

[0138] In one possible implementation, the determining module 302 is specifically used to: detect the wireless signal strength between the tire pressure detection sensor in each tire of the target vehicle and the vehicle body receiver; if the change in the wireless signal strength corresponding to at least one tire of the target vehicle within a preset time period is greater than a preset change, then determine that the target vehicle triggers a level one alarm.

[0139] In one possible implementation, the determining module 302 is specifically used to: determine the vehicle body attitude angle of the target vehicle and / or the distance between each wheel of the target vehicle and the ground based on the inertial measurement unit; and determine that the target vehicle triggers a secondary alarm when there is a change in the vehicle body attitude angle, or when there is at least one wheel with a distance greater than a preset distance.
