Description

Technical Field

[0001] The present application relates to the field of vehicles, and more specifically, to a method, a device, a vehicle and a storage medium for preventing theft of a vehicle in the field of vehicles. Background Art

[0002] As an indispensable means of transportation in daily life, the safety of cars has always received widespread attention. In particular, convertible vehicles are more likely to become targets of theft due to their structural characteristics. In order to meet this challenge, vehicle anti-theft technology has evolved from single means such as early mechanical locks, electronic keys, and anti-theft alarms to comprehensive solutions that integrate multiple technologies.

[0003] Although early anti-theft technologies can prevent vehicle theft to a certain extent, their anti-theft capabilities are limited and easy to be cracked. With the development of electronic technology, modern vehicle anti-theft systems have achieved a transformation from a single mechanical or electronic system to a comprehensive solution integrating multiple technologies. These solutions may include advanced technologies such as GPS positioning, remote control, and vehicle status monitoring, which significantly improve the anti-theft effect of vehicles.

[0004] Although modern vehicle anti-theft technology has made significant progress, there are still some shortcomings. In particular, when the remote communication terminal is disassembled, the existing anti-theft technology is not comprehensive and reliable enough. Summary of the invention

[0005] The present application provides a vehicle anti-theft method, device, vehicle and storage medium. The method can provide a new anti-theft means, which can prevent the vehicle's power system from starting when the T-Box is disassembled, thereby preventing the vehicle from being illegally driven away, improving the efficiency of the vehicle's anti-theft system, and reducing the possibility of vehicle theft.

[0006] In a first aspect, a vehicle anti-theft method is provided, the method comprising: when it is detected that a vehicle has stopped running, starting timing to obtain a timing duration; when the timing duration is less than a preset duration, collecting a target signal corresponding to a target component; wherein the target signal is a signal uploaded to the cloud by a remote communication terminal of the vehicle; based on the target signal, determining whether the remote communication terminal of the vehicle is at risk of being disassembled; and when it is determined that the remote communication terminal is at risk of being disassembled, restricting the vehicle's power system from starting.

[0007] In the above technical solution, within the preset time after the vehicle stops running, by collecting the target signal of the target component uploaded to the cloud by the remote communication terminal, it is determined whether the remote communication terminal (Telematics Box, T-Box) is at risk of being disassembled. If it is determined that the remote communication terminal is at risk of being disassembled, it is determined that the vehicle is at risk of being stolen, and then the power system of the vehicle is restricted from starting, which provides a new anti-theft means, so that the vehicle can timely discover that the vehicle's remote communication terminal may be disassembled and the vehicle is at risk of being stolen based on the target signal within the preset time after the vehicle stops running. If it is determined that the vehicle is at risk of being stolen, the power system of the vehicle is timely restricted from starting, thereby preventing the vehicle from being illegally driven away, providing a more comprehensive anti-theft technology. This rapid response mechanism can greatly improve the efficiency of the anti-theft system and reduce the possibility of vehicle theft.

[0008] In combination with the first aspect, in some possible implementations, based on the target signal, it is determined whether the vehicle's remote communication terminal is at risk of being disassembled, including: determining whether the target signal is the same as a preset signal; wherein the preset signal is a signal corresponding to a target component uploaded to the cloud when the communication terminal has not been disassembled; when the target signal is different from the preset signal, it is determined that the remote communication terminal is at risk of being disassembled.

[0009] In the above technical solution, the target signal is specific data in an existing technical setting for monitoring the target component in the vehicle. This method, which relies on the specific data that already exists in the vehicle's monitoring of the target component to determine whether the vehicle is at risk of being stolen, has a higher degree of confidence than traditional anti-theft systems. The method is very clever and provides a new anti-theft technology.

[0010] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, when the target component is a power battery, the target signal is the first identification code of the battery cell with the highest temperature in the power battery of the vehicle, and the preset signal includes multiple identification codes corresponding to the power battery; judging whether the target signal is the same as the preset signal includes: judging whether the first identification code is the same as any one of the multiple identification codes corresponding to the power battery; wherein the power battery includes multiple battery cells, and each battery cell corresponds to an identification code; when the target signal is different from the preset signal, determining that the remote communication terminal is at risk of being disassembled includes: when the first identification code is different from each of the multiple identification codes corresponding to the power battery, determining that the remote communication terminal is at risk of being disassembled.

[0011] In the above technical solution, the first identification code is specific data in an existing technical setting in the vehicle to prevent battery fires. By comparing the first identification code with multiple identification codes corresponding to the power battery, when the first identification code is different from the identification codes of multiple battery cells included in the power battery, it is determined that the T-Box may be disassembled and the vehicle is at risk of theft. This method, which relies on specific data existing in the vehicle's power battery to determine whether the vehicle is at risk of theft, has higher confidence than traditional anti-theft systems, the method is clever, and the judgment result is more accurate, thereby enhancing the vehicle's anti-theft performance.

[0012] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, when the target component is a component in a vehicle that needs to be monitored for abnormal conditions, the target signal includes: a status signal of the target component, a preset signal includes a first signal characterizing that the target component is normal and a second signal characterizing that the target component is abnormal; judging whether the target signal is the same as the preset signal includes: judging whether the status signal is the same as the first signal or the second signal; in a case where the target signal is different from the preset signal, determining that the remote communication terminal is at risk of being disassembled, including: in a case where the status signal is different from both the first signal and the second signal, determining that the remote communication terminal is at risk of being disassembled.

[0013] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, when the first identification code is different from each of the multiple identification codes corresponding to the power battery, it is determined that the remote communication terminal is at risk of being disassembled, including: when the first identification code is different from each of the multiple identification codes corresponding to the power battery, in response to the start of the vehicle, obtaining the second identification code of the battery cell with the highest temperature in the current power battery; determining whether the second identification code is the same as any one of the multiple identification codes corresponding to the power battery; when the second identification code is different from each of the multiple identification codes corresponding to the power battery, determining that the remote communication terminal is at risk of being disassembled.

[0014] In the above technical solution, it is first determined that the T-Box is at risk of being disassembled based on the fact that the first identification code is different from each of the multiple identification codes corresponding to the power battery, and the second identification code is obtained after the vehicle is started, and a second confirmation is performed based on the second identification code to determine whether the T-Box is disassembled. When the second identification code is different from each of the multiple identification codes corresponding to the power battery, it is determined again that the T-Box is at risk of being disassembled, and then it is determined that the vehicle is at risk of being stolen. This secondary confirmation method takes into account more comprehensive considerations, improves the accuracy of judging whether the vehicle is at risk of being stolen, and avoids the misjudgment of the vehicle being stolen when the vehicle's T-Box is repaired.

[0015] In combination with the first aspect and the above-mentioned implementation methods, in certain possible implementation methods, when it is determined that the remote communication terminal is at risk of being disassembled, the vehicle's power system is restricted from starting, including: when it is determined that the remote communication terminal is at risk of being disassembled, detecting the status of the power battery and the vehicle's engine; when the main positive relay and / or the main negative relay of the power battery are in a disconnected state and the engine is in an off state, restricting the vehicle's power system from starting.

[0016] In combination with the first aspect and the above-mentioned implementations, in some possible implementations, when it is determined that the remote communication terminal is at risk of being disassembled, the method further includes: allowing the power system of the vehicle to be remotely started via the smart terminal.

[0017] In the above technical solution, when it is determined that the T-Box is at risk of being disassembled, the vehicle's power system is allowed to be remotely started through the smart terminal, so that the owner can start the vehicle without the T-BOX being disassembled, avoiding the situation where the vehicle is misjudged as stolen when the T-Box fails, resulting in the vehicle being unable to start and drive.

[0018] In summary, this application determines whether the vehicle's T-Box is at risk of being disassembled by collecting the target signal of the target component uploaded to the cloud by the remote communication terminal within a preset time after determining that the vehicle has stopped running, such as the first identification code of the battery cell with the highest temperature in the power battery, and the status signal of the component that needs to be monitored in an abnormal state. The target signal is specific data in an existing technical setting for monitoring the target component in the vehicle. This method, which relies on the specific data that already exists in the vehicle's monitoring of the target component, determines whether the vehicle is at risk of being stolen. Compared with traditional anti-theft systems, the method is very clever and provides a new anti-theft technology. In the judgment process, it is first determined based on the first identification code whether the T-Box is at risk of being disassembled, and then after the vehicle is started, a second confirmation is performed based on the second identification code to determine whether the T-Box is disassembled to determine whether the vehicle is at risk of being stolen. This secondary confirmation method is more comprehensive, improves the accuracy of judging whether the vehicle is at risk of being stolen, and avoids misjudging the vehicle as being stolen when the vehicle's T-Box is repaired. While restricting the power system from starting, it allows the power system to be started remotely through the smart terminal, so that the owner can start the vehicle without dismantling the T-BOX, avoiding the situation where the T-Box fails and the vehicle is misjudged as stolen, resulting in the vehicle being unable to start and drive.

[0019] In a second aspect, a vehicle anti-theft device is provided, which includes: a timing module, which is used to start timing and obtain a timing duration when it is detected that the vehicle has stopped running; a collection module, which is used to collect a target signal corresponding to a target component when the timing duration is less than a preset duration; wherein the target signal is a signal uploaded to the cloud by the vehicle's remote communication terminal; a judgment module, which is used to judge whether the vehicle's remote communication terminal is at risk of being disassembled based on the target signal; and a control module, which is used to restrict the vehicle's power system from starting when it is determined that the remote communication terminal is at risk of being disassembled.

[0020] In combination with the second aspect, in some possible implementations, the judgment module is specifically used to determine whether the target signal is the same as a preset signal; wherein the preset signal is a signal corresponding to a target component uploaded to the cloud when the communication terminal is not disassembled; when the target signal is not the same as the preset signal, it is determined that the remote communication terminal is at risk of being disassembled.

[0021] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, when the target component is a power battery, the target signal is the first identification code of the battery cell with the highest temperature in the power battery of the vehicle, and the preset signal includes multiple identification codes corresponding to the power battery; the judgment module is specifically used to determine whether the first identification code is the same as any one of the multiple identification codes corresponding to the power battery; wherein the power battery includes multiple battery cells, each battery cell corresponding to an identification code; when the first identification code is different from each of the multiple identification codes corresponding to the power battery, it is determined that the remote communication terminal is at risk of being disassembled.

[0022] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, when the target component is a component in a vehicle that needs to be monitored for abnormal conditions, the target signal includes: a status signal of the target component, the preset signal includes a first signal indicating that the target component is normal and a second signal indicating that the target component is abnormal; the judgment module is specifically used to determine whether the status signal is the same as the first signal or the second signal; when the status signal is different from both the first signal and the second signal, it is determined that the remote communication terminal is at risk of being disassembled.

[0023] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the judgment module is also used to, in response to the start of the vehicle, obtain the second identification code of the battery cell with the highest temperature in the current power battery when the first identification code is different from each of the multiple identification codes corresponding to the power battery; judge whether the second identification code is the same as any one of the multiple identification codes corresponding to the power battery; and determine that the remote communication terminal is at risk of being disassembled when the second identification code is different from each of the multiple identification codes corresponding to the power battery.

[0024] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the control module is specifically used to, when it is determined that the remote communication terminal is at risk of being disassembled, detect the status of the power battery and the engine of the vehicle; when the main positive relay and / or the main negative relay of the power battery are in the disconnected state and the engine is in the off state, restrict the vehicle's power system from starting.

[0025] In combination with the second aspect and the above-mentioned implementations, in some possible implementations, the device further includes: a start-up permission module, which is used to allow the vehicle's power system to be remotely started through the smart terminal when it is determined that the remote communication terminal is at risk of being disassembled.

[0026] In a third aspect, a vehicle is provided, comprising 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, so that the vehicle executes the method in the first aspect or any possible implementation of the first aspect.

[0034] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0035] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying 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 the features.

[0036] As global environmental issues become increasingly severe, emission reduction has become an important task for the development of the automotive industry. As a new type of automotive product, hybrid vehicles can not only reduce fuel consumption but also reduce emissions. Therefore, hybrid vehicles will become the mainstream of the automotive industry for a long time in the future.

[0037] The hybrid system has multiple working modes: 1. Pure electric drive, in which case the engine is not working and the motor is completely driven by the battery; 2. Engine-driven power generation, in which case the engine is used to generate electricity for the battery, and then the battery drives the motor; 3. The engine drives the transmission system independently, the battery and the motor do not work, and the transmission system is completely driven by the engine; 4. Parallel mode, in which the engine drives the transmission system while the battery also powers the motor, which is equivalent to the "engine" and "battery, generator" working in parallel.

[0038] As an indispensable means of transportation in daily life, the safety of cars has always received widespread attention. Hybrid vehicles include both the engine of pure oil vehicles and the high-voltage system of pure electric vehicles. The anti-theft technology for hybrid vehicles can be applied to both pure oil vehicles and pure electric vehicles. Although modern anti-theft technology for hybrid vehicles has made significant progress, there are still some shortcomings, especially when facing the situation where the remote communication terminal is disassembled, the existing anti-theft technology is not comprehensive and reliable enough.

[0039] Based on this, the present application proposes a vehicle anti-theft method and provides a new anti-theft means, which enables the vehicle to promptly detect the risk of theft based on the first identification code within a preset time after stopping operation, and restrict the power system from starting when there is a risk of theft, thereby preventing the vehicle from being stolen, providing a more comprehensive and reliable anti-theft technology and improving the safety of the vehicle.

[0040] Figure 1 It is a schematic flow chart of a vehicle theft prevention method provided in an embodiment of the present application.

[0041] For example, Figure 1 As shown, the method 100 includes: Step 101, when it is detected that the vehicle stops running, start timing to obtain the timing duration; Step 102, when the timing duration is less than the preset duration, collecting the target signal corresponding to the target component; Among them, the target signal is the signal uploaded to the cloud by the vehicle's remote communication terminal.

[0042] Step 103, based on the target signal, determining whether the remote communication terminal of the vehicle is at risk of being disassembled; Step 104 : If it is determined that the remote communication terminal is at risk of being disassembled, the power system of the vehicle is restricted from starting.

[0043] exist Figure 1 In the embodiment shown, within a preset time after the vehicle stops running, by collecting the target signal of the target component uploaded to the cloud by the remote communication terminal, it is determined whether the remote communication terminal (Telematics Box, T-Box) of the vehicle is at risk of being disassembled. If it is determined that the remote communication terminal is at risk of being disassembled, it is determined that the vehicle is at risk of being stolen, and then the power system of the vehicle is restricted from starting, which provides a new anti-theft means, so that the vehicle can timely discover that the vehicle's remote communication terminal may be disassembled and the vehicle is at risk of being stolen based on the target signal within a preset time after the vehicle stops running. If it is determined that the vehicle is at risk of being stolen, the power system of the vehicle is timely restricted from starting, thereby preventing the vehicle from being illegally driven away, providing a more comprehensive anti-theft technology, and this rapid response mechanism can greatly improve the efficiency of the anti-theft system and reduce the possibility of vehicle theft.

[0044] Below Figure 1 The specific implementation of each step in the embodiment shown is described in detail: In step 101, the vehicle stops running, which means that the vehicle's power system (such as the engine or motor) no longer provides power and the vehicle is in a stationary state. At this time, the user usually gets off the vehicle and parks the vehicle at the current location for a certain period of time. The vehicle will be in an unattended parking state, and the vehicle is prone to theft risks, especially convertible vehicles are prone to theft risks after being disassembled in the T-Box.

[0045] The vehicle includes a low-voltage system that is responsible for powering various vehicle and auxiliary systems in the vehicle. After the vehicle is determined to have stopped running, the vehicle's low-voltage system usually continues to work for a certain period of time, and the low-voltage system may include a timer. When the vehicle is determined to have stopped running, the timer starts counting and obtains the timing duration.

[0046] In a possible implementation, the method further includes: determining that the vehicle stops running when it is detected that the main positive relay and / or the main negative relay of the power battery are disconnected, and / or when it is detected that the engine of the vehicle is turned off.

[0047] The vehicle may be a hybrid vehicle. A hybrid vehicle includes a power battery, which is also referred to as a high-voltage battery in some embodiments. The power battery supplies power to a motor to rotate the motor, and the motor outputs power to drive the vehicle.

[0048] Figure 2 This is a circuit diagram of a power battery driving a motor provided in an embodiment of the present application.

[0049] For example, Figure 2 As shown, it includes: a power battery 201 , a main positive relay 202 , a main negative relay 203 and a motor 204 .

[0050] The positive electrode of the power battery 201 is connected to the motor 204 through the main positive relay 202, and the negative electrode of the power battery 201 is connected to the motor 204 through the main negative relay 203. When the power battery is required to output power to drive the vehicle, the main positive relay and the main negative relay are closed, the power battery supplies power to the motor 204, the motor 204 rotates, and the output power drives the vehicle to travel.

[0051] In some embodiments, the circuit further includes a pre-charge resistor 205 and a pre-charge relay 206. When the high-voltage battery begins to discharge, the pre-charge relay 206 closes first, and the current flows to the motor 204 through the pre-charge resistor 205. The motor is gradually fully charged and the current gradually increases. When the motor is fully charged, the pre-charge relay is disconnected and the pre-charge resistor exits the circuit. The main positive relay is closed, the high-voltage battery is directly connected to the motor, and the motor starts to operate normally. This process ensures a smooth start of the motor, reduces the impact on the motor and its related components, and extends their service life.

[0052] When the vehicle uses the power battery to output power, it can detect whether the main positive relay and / or the main negative relay of the power battery are disconnected from the closed state. If it is detected that the main positive relay and / or the main negative relay of the power battery are disconnected, it is determined that the vehicle stops running.

[0053] The hybrid vehicle also includes an engine, and the hybrid vehicle can also output power through the rotation of the engine to drive the vehicle. When the vehicle uses the engine to output power, it can be detected whether the engine is turned off from the running state. If it is detected that the engine is turned off from the running state, it is determined that the vehicle stops running.

[0054] When the vehicle is driven by the power output of the power battery and the engine, it is necessary to detect whether the main positive relay and / or the main negative relay of the power battery are disconnected from the closed state and whether the engine is shut down from the running state. If it is detected that the main positive relay and / or the main negative relay of the power battery are disconnected from the closed state and the engine is shut down from the running state, it is determined that the vehicle has stopped running.

[0055] In step 102, the preset duration may be the delayed working duration of the low-pressure system in the vehicle after the vehicle stops running.

[0056] It is understandable that immediately shutting off the low-voltage system after the vehicle stops running may cause some important safety functions to not work properly. Most vehicle systems require time to complete data preservation, system reset or shutdown processes after the vehicle stops running. In order to meet the needs of safety and system reset, the low-voltage system will be shut down for a certain period of time after the vehicle stops running.

[0057] The target signal corresponding to the target component can be specifically: the vehicle needs the remote communication terminal to upload to the cloud in real time or based on a smaller preset period (such as 1s, 2s), so that the cloud can monitor the signal of the target component in the vehicle. Within the preset time, the vehicle can collect the target signal corresponding to the target component that needs to be uploaded to the cloud by the remote communication terminal.

[0058] Specifically, a power system control device may be provided in the vehicle. After determining that the vehicle has stopped running, the low-voltage system supplies power to the power system control device so that the power system control device collects target signals corresponding to target components uploaded to the cloud by the remote communication terminal within a preset time period.

[0059] The target components may include the vehicle's power battery, engine, motor, exhaust pipe, etc. The target signal is the signal corresponding to any one of the power battery, engine, motor, exhaust pipe, etc., which needs to be uploaded to the cloud by the remote communication terminal in real time or based on a smaller preset period.

[0060] In step 103, the target signal is the data collected by the T-Box to be uploaded to the cloud, and the state of the T-Box can be determined based on the first signal. Specifically, it can be determined whether the T-Box is disassembled based on the target signal, and whether the vehicle is at risk of theft based on whether the T-Box is disassembled. Generally, when it is determined that the T-Box is disassembled, it is determined that the vehicle is at risk of theft.

[0061] It is understandable that the T-Box is an important component in the vehicle, which is usually used to realize remote communication and vehicle status monitoring functions. It uploads the vehicle's status information to the cloud server through wireless communication technology (such as cellular network), providing the following functions: Remote monitoring: real-time monitoring of the vehicle's location, speed, battery status, etc. Anti-theft function: through location tracking and status monitoring, it helps to confirm whether the vehicle is stolen. Remote diagnosis: upload the vehicle's fault information to facilitate remote diagnosis and maintenance. Remote control: allows remote start, lock / unlock the vehicle and other operations.

[0062] If the T-Box in the vehicle is disassembled, it means that the vehicle status information cannot be uploaded to the cloud server, resulting in the failure of the vehicle monitoring function. The vehicle cannot be located and tracked, the anti-theft function of the vehicle is invalid, and it is more difficult to recover the stolen vehicle. Therefore, when stealing a car, thieves usually disassemble the T-Box of the vehicle to avoid being tracked, making the vehicle easier to be stolen. Whether the vehicle is at risk of theft can be determined based on whether the T-Box is disassembled.

[0063] Figure 3 This is a schematic diagram of T-Box power management provided in an embodiment of the present application.

[0064] For example, Figure 3 As shown, the 12V battery in the vehicle's low-voltage system supplies power to the T-Box. The power management system inside the T-box is responsible for converting the 12V power into power of different voltage levels to meet the needs of different components.

[0065] Specifically, it includes: converting 12V power into 5V power for the vehicle's Controller Area Network (CAN) communication. Converting 12V power into 3.8V power for the General Packet Radio Service (GPRS) module for information communication. GPRS is an early mobile data communication technology used for data transmission between the T-box and external networks (such as cellular networks). Converting 12V power into 3.3V power is mainly used to supply the microcontroller and other auxiliary circuits, such as the watchdog timer. The microcontroller is the core processor of the T-box, and the watchdog is a hardware protection mechanism used to monitor and recover from possible faults in the microcontroller.

[0066] In one possible implementation, based on the target signal, it is determined whether the remote communication terminal of the vehicle is at risk of being disassembled, including: determining whether the target signal is the same as a preset signal; wherein the preset signal is a signal corresponding to a target component uploaded to the cloud when the communication terminal has not been disassembled; and when the target signal is not the same as the preset signal, it is determined that the remote communication terminal is at risk of being disassembled.

[0067] For a certain target component in the vehicle, multiple preset signals can be set in advance, and different preset signals correspond to different operating information of the target component. The vehicle can obtain the current operating information of the target component. When the communication terminal is not disassembled, the preset signal corresponding to the current operating information of the target component can be uploaded to the cloud, so that the cloud can determine the current operating information of the target component corresponding to the target signal based on the target signal and monitor the target component. At this time, the target signal collected by the power system control device is one of the preset signals.

[0068] When the communication terminal is disassembled, due to data transmission interruption or abnormality, the power system control device will collect a default signal or an error signal as the target signal of the target component, and the default signal or the error signal is different from the preset signal of the target component. Therefore, after collecting the target signal corresponding to the target component, it can be determined whether the target signal is the same as the preset signal corresponding to the target component. If it is determined that the target signal is different from the preset signal, it can be determined that the communication terminal is at risk of being disassembled.

[0069] In the above method, the target signal is specific data in an existing technical setting for monitoring the target components in the vehicle. This method, which relies on the specific data that already exists in the vehicle's target component monitoring itself to determine whether the vehicle is at risk of being stolen, has a higher degree of confidence than traditional anti-theft systems. The method is very clever and provides a new anti-theft technology.

[0070] In one possible implementation, when the target component is a power battery, the target signal is the first identification code of the battery cell with the highest temperature in the power battery of the vehicle, and the preset signal includes multiple identification codes corresponding to the power battery; judging whether the target signal is the same as the preset signal comprises: judging whether the first identification code is the same as any one of the multiple identification codes corresponding to the power battery; wherein the power battery comprises multiple battery cells, and each battery cell corresponds to an identification code; in a case where the target signal is different from the preset signal, determining that the remote communication terminal is at risk of being disassembled comprises: in a case where the first identification code is different from each of the multiple identification codes corresponding to the power battery, determining that the remote communication terminal is at risk of being disassembled.

[0071] When the target component is a power battery, the target signal may specifically include: a first identification code of a battery cell with the highest temperature in the power battery of the vehicle.

[0072] The identification code refers to an identifier used to uniquely identify each independent battery cell in the power battery, which can be a numerical value. The power battery (i.e., high-voltage battery) is an integrated module composed of multiple groups of small batteries, each of which can be called a battery cell.

[0073] In order to prevent the battery temperature from being too high and causing a fire, the temperature of each battery cell will be collected, and the identification code of the battery cell with the highest temperature will be uploaded to the cloud by the T-Box. The system control device can collect the identification code of the battery cell with the highest temperature in the T-Box to be uploaded to the cloud in real time to obtain the first identification code.

[0074] The power battery includes multiple groups of small batteries or multiple small batteries, and each small battery group or small battery can be called a battery cell. Therefore, the power battery includes multiple battery cells. Since each battery cell corresponds to an identification code that uniquely identifies the battery cell, the power battery corresponds to multiple identification codes. It can be understood that each battery cell corresponds to an identification code that uniquely identifies the battery cell, so the multiple identification codes corresponding to the power battery are different.

[0075] For example, the power battery includes 254 small battery groups, that is, the power battery includes 254 independent battery cells, and the identification code of each battery cell can be numbers 1 to 254. There is a battery cell with the highest temperature in the power battery, and the identification code of the battery cell can be any one of the numbers 1 to 254, that is, the first identification code of the battery cell with the highest temperature that the collected T-Box will upload to the cloud should be any one of the numbers 1 to 254.

[0076] It is understandable that any battery cell in the power battery may be the battery cell with the highest temperature, that is, the identification code of any battery cell in the power battery may be uploaded to the cloud when the T-Box is not disassembled. Therefore, the preset signal includes the identification codes corresponding to all battery cells included in the power battery.

[0077] When the T-Box is disassembled, due to data transmission interruption or abnormality, the power system control device will collect a default value or an error value as the first identification code, and the default value or the error value is different from the identification codes of the multiple battery cells included in the power battery. Therefore, after obtaining the first identification code, it can be determined whether the first identification code is the same as any one of the multiple identification codes corresponding to the power battery. When it is determined that the first identification code is different from each of the multiple identification codes corresponding to the power battery, it is determined that the T-Box is at risk of being disassembled, that is, it is determined that the vehicle is at risk of being stolen.

[0078] Exemplarily, the default value or error value is, for example, "0" or a value greater than 254. After obtaining the first identification code, it can be determined whether the number corresponding to the first identification code is in the range of 1 to 254. When it is determined that the first identification code is not in the range of 1 to 254, it is determined that the first identification code is different from each of the multiple identification codes corresponding to the power battery, that is, it is determined that the T-Box is at risk of being disassembled, and that the vehicle is at risk of being stolen.

[0079] In the above method, the first identification code is specific data in an existing technical setting in the vehicle to prevent battery fires. By comparing the first identification code with multiple identification codes corresponding to the power battery, when the first identification code is different from the identification codes of multiple battery cells included in the power battery, it is determined that the T-Box may be disassembled and the vehicle is at risk of theft. This method, which relies on specific data existing in the vehicle's power battery to determine whether the vehicle is at risk of theft, has a higher confidence level than traditional anti-theft systems, the method is very clever, and the judgment result is more accurate, thereby enhancing the vehicle's anti-theft performance.

[0080] In one possible implementation, when the first identification code is different from each of the multiple identification codes corresponding to the power battery, it is determined that the remote communication terminal is at risk of being disassembled, including: when the first identification code is different from each of the multiple identification codes corresponding to the power battery, in response to the start of the vehicle, obtaining the second identification code of the battery cell with the highest temperature in the current power battery; determining whether the second identification code is the same as any one of the multiple identification codes corresponding to the power battery; when the second identification code is different from each of the multiple identification codes corresponding to the power battery, determining that the remote communication terminal is at risk of being disassembled.

[0081] When it is determined that the first identification code is different from each of the multiple identification codes corresponding to the power battery, it can be determined that the T-Box was disassembled after the vehicle stopped running, and based on this, it can be preliminarily determined that the vehicle is at risk of theft. In order to further determine whether the vehicle is at risk of theft, in response to the vehicle being restarted, the second identification code of the battery cell with the highest temperature in the power battery can be obtained again after it is preliminarily determined that the vehicle is at risk of theft. Determine whether the second identification code is the same as any of the multiple identification codes corresponding to the power battery to determine whether the T-Box is actually disassembled, that is, determine whether the T-Box was installed back before the vehicle was started, and then further determine whether the vehicle is at risk of theft.

[0082] Among them, the power system control device can determine that the vehicle is started again when it is detected that the vehicle's engine is started and / or the main positive relay and the main negative relay of the power battery are closed.

[0083] It is understandable that if the vehicle has a T-Box repair, the maintenance personnel may remove the T-Box of the vehicle within a preset time to perform corresponding repairs, and reinstall the T-Box on the vehicle after the preset time. At this time, although the first identification code obtained within the preset time after stopping operation is different from each of the multiple identification codes corresponding to the power battery. After the T-Box is reinstalled on the vehicle, the second identification code obtained when the vehicle is restarted is a normal value, that is, the second identification code is the same as one of the multiple identification codes corresponding to the power battery. At this time, it can be determined that the vehicle has only been repaired, the T-Box has not been disassembled, and the vehicle is not at risk of being stolen.

[0084] When the second identification code obtained after the vehicle is started is still different from each of the multiple identification codes corresponding to the power battery, it can be determined that there is a risk that the T-Box of the vehicle has been disassembled after it stops running, and the T-Box has not been installed back into the vehicle when the vehicle is started again. At this time, it can be determined that the vehicle is at risk of being stolen.

[0085] In the above method, it is first determined that the T-Box is at risk of being disassembled based on the fact that the first identification code is different from each of the multiple identification codes corresponding to the power battery, and the second identification code is obtained after the vehicle is started. A second confirmation is performed based on the second identification code to determine whether the T-Box is disassembled. When the second identification code is different from each of the multiple identification codes corresponding to the power battery, it is determined again that the T-Box is at risk of being disassembled, and then it is determined that the vehicle is at risk of being stolen. This secondary confirmation method takes into account more comprehensive considerations, improves the accuracy of judging whether the vehicle is at risk of being stolen, and avoids the misjudgment of the vehicle being stolen when the vehicle's T-Box is repaired.

[0086] In one possible implementation, when the target component is a component in a vehicle that needs to be monitored for abnormal conditions, the target signal includes: a status signal of the target component, a preset signal includes a first signal indicating that the target component is normal and a second signal indicating that the target component is abnormal; determining whether the target signal is the same as the preset signal includes: determining whether the status signal is the same as the first signal or the second signal; when the target signal is different from the preset signal, determining that the remote communication terminal is at risk of being disassembled, including: when the status signal is different from both the first signal and the second signal, determining that the remote communication terminal is at risk of being disassembled.

[0087] The components in the vehicle that need to be monitored for abnormal conditions in real time may specifically include: the engine, the motor, the exhaust pipe, etc. When the target component is the engine, the status signal may specifically be a status signal indicating whether the emission parameters of the engine are normal; when the target component is the motor, the status signal may specifically be a status signal indicating whether the motor is operating normally; when the target component is the exhaust pipe, the status signal may specifically be a status signal indicating whether the particulate filter in the exhaust pipe is normal.

[0088] In some embodiments, the components in the vehicle that need to be monitored for abnormal conditions in real time may also include a power battery. When the target component is a power battery, the status signal may specifically be a status signal indicating whether the voltage or current of the power battery is normal.

[0089] It is understandable that there are some target components in the vehicle that need to be monitored or predicted in real time to see if the status of the target components is abnormal, so that the user can be promptly prompted when an abnormality is detected in the target components, allowing the user to perform corresponding operations based on the prompts to ensure the driving safety of the vehicle.

[0090] When the T-Box is not disassembled, when the target component is normal, the T-Box needs to upload a first signal to the cloud indicating that the target component is normal; when the target component is abnormal, the T-Box needs to upload a second signal to the cloud indicating that the component is abnormal.

[0091] Exemplarily, the target component is a power battery, and the status signal is a signal indicating whether the voltage of the power battery is normal. When the voltage of each battery cell of the power battery is within a normal range (for example, between 3.0V and 4.2), the T-Box uploads a first signal indicating that the power battery voltage is normal to the cloud, for example, 0. When the voltage of a battery cell of the power battery is not within a normal range (for example, between 3.0V and 4.2), the T-Box uploads a second signal indicating that the power battery voltage is abnormal to the cloud, for example, 1.

[0092] It is understandable that the target component may be in a normal state or in an abnormal state, that is, when the T-Box is not disassembled, it may upload a first signal to the cloud or a second signal to the cloud. Therefore, the preset signal includes a first signal indicating that the target component is normal and a second signal indicating that the target component is abnormal.

[0093] When the T-Box is disassembled, due to data transmission interruption or abnormality, the power system control device will collect a default signal or an error signal as the status signal of the target component. The default signal or the error signal is different from the first signal or the second signal corresponding to the target component. Therefore, after obtaining the status signal, it can be determined whether the status signal is the same as the first signal representing the normal component and the second signal representing the abnormal component. When it is determined that the status signal is different from the first signal and the second signal, it is determined that the T-Box is at risk of being disassembled, that is, it is determined that the vehicle is at risk of being stolen.

[0094] Exemplarily, the default signal or error signal is, for example, a signal other than 0 or 1, such as 2, 3, 4, etc. After obtaining the status signal of the power battery, it can be determined whether the status signal is the same as the signal 0 representing a normal power battery voltage or the signal 1 representing an abnormal power battery voltage. When the status signal of the power battery is neither 0 nor 1, it is determined that the T-Box is at risk of being disassembled, that is, the vehicle is at risk of being stolen.

[0095] In some embodiments, when the component is an engine, when the emission parameters of the engine are within the qualified range, the status signal uploaded by T-Box to the cloud is a first signal indicating that the engine is normal, and when the emission parameters of the engine are not within the qualified range, the status signal uploaded by T-Box to the cloud is a second signal indicating that the engine is abnormal. When the component is a motor, when the reliability of the motor is predicted to be greater than or equal to the preset reliability (e.g., 80%), the status signal uploaded by T-Box to the cloud is a first signal indicating that the motor is normal, and when the reliability of the motor is predicted to be less than the preset reliability (e.g., 80%), the status signal uploaded by T-Box to the cloud is a second signal indicating that the motor is abnormal. When the component is an exhaust pipe, when the particulate filter in the exhaust pipe is not removed, the status signal uploaded by T-Box to the cloud is a first signal indicating that the exhaust pipe is normal, and when the particulate filter in the exhaust pipe is removed, the status signal uploaded by T-Box to the cloud is a second signal indicating that the exhaust pipe is abnormal.

[0096] Among them, when the component is an exhaust pipe, the method for determining whether the particulate trap is disassembled includes: obtaining two pressures collected by pressure sensors on both sides of the particulate trap, and determining that the particulate trap is disassembled when the pressure difference between the two pressures is less than a preset pressure difference.

[0097] The process of determining whether the T-Box is disassembled based on the status signal of any one of the above-mentioned engine, motor, and exhaust pipe components is similar to the process of determining whether the T-Box is disassembled based on the status signal of the power battery voltage, and will not be repeated here.

[0098] It can be understood that the status signal corresponding to the above-mentioned target component is recorded as the first status signal. When judging whether the T-Box is disassembled based on the first status signal, if the vehicle is detected to be started when it is determined that the first status signal is different from both the first signal and the second signal, the second status signal of the target component after the vehicle is started can be obtained, and it can be judged again whether the second status signal is the same as the first signal representing the normal target component and the abnormal second signal. When it is judged that the second status signal is different from both the first signal and the second signal, it is determined that the remote communication terminal is at risk of being disassembled.

[0099] In step 104, restricting the vehicle's power system from starting may include: controlling the vehicle to no longer execute a main positive relay and / or main negative relay closing command; controlling the vehicle to no longer execute an engine start command, so as to prevent the stolen vehicle from being able to drive itself and prevent the vehicle from being stolen.

[0100] In one possible implementation, when it is determined that the remote communication terminal is at risk of being disassembled, the vehicle's power system is restricted from starting, including: when it is determined that the remote communication terminal is at risk of being disassembled, detecting the status of the power battery and the vehicle's engine; when the main positive relay and / or the main negative relay of the power battery are in a disconnected state and the engine is in an off state, restricting the vehicle's power system from starting.

[0101] After the vehicle is restarted, it is determined based on the second identification code that the T-Box is at risk of being disassembled. If the vehicle is at risk of being stolen, the vehicle is likely to have been stolen. At this time, it is necessary to restrict the vehicle's power system from starting while ensuring the vehicle's safety.

[0102] It is understandable that the vehicle is currently in the starting state, the main positive relay and the main negative relay of the vehicle's power battery are in the closed state and / or the engine is in the running state. At this time, directly restricting the vehicle's power system from starting is likely to cause vehicle safety issues.

[0103] Specifically, the status of the main positive relay, the main negative relay and the engine of the vehicle's high-voltage battery can be monitored. After the main positive relay and the main negative relay are disconnected and the engine is turned off, it is determined that the vehicle is in a safe state, and then the vehicle's power system is restricted from starting.

[0104] As in the above embodiment, restricting the vehicle's power system from starting may include: controlling the vehicle to no longer execute a main positive relay and / or main negative relay closing command; controlling the vehicle to no longer execute an engine start command, so as to prevent the stolen vehicle from being able to drive itself and prevent the vehicle from being stolen.

[0105] In some embodiments, the vehicle starting method may include local starting and remote starting.

[0106] Among them, local start refers to the operation performed inside the vehicle or directly through the vehicle's own control system to start the vehicle's power system. Local start specifically includes: Traditional key start: insert a metal key into the ignition switch and turn it to start the engine. Keyless start (one-button start): Enter the vehicle by carrying a key with a wireless transmitter and press the start button to start the engine. Touch screen start: In some high-end models, the engine is started by a virtual button on the vehicle's built-in touch screen interface. Voice start: Start the vehicle through voice commands.

[0107] Remote start refers to the process of starting a vehicle through contactless remote communication. Specifically, it includes: starting the vehicle through application programs on smartphones, tablets, etc.: starting the vehicle by sending a start command through applications on smartphones, tablets, etc.; starting the vehicle with a dedicated remote control: starting the vehicle within a certain range using a dedicated remote control equipped with the vehicle.

[0108] Since the user may leave the dedicated remote control or key in the vehicle, if the vehicle is stolen, the thief can not only start the vehicle through the above-mentioned local start method, but also remotely start the vehicle through the dedicated remote control. Therefore, restricting the vehicle's power system from starting specifically includes: restricting the vehicle's power system from starting through the local start method and the dedicated remote control.

[0109] In a possible implementation, when it is determined that the T-Box is at risk of being disassembled, the method further includes: allowing the power system of the vehicle to be remotely started via a smart terminal.

[0110] Among them, the smart terminal can specifically be a smart terminal such as a mobile phone, tablet, bracelet, etc. that has passed the vehicle's verification and established a secure communication connection with the vehicle.

[0111] The steps of remotely starting the vehicle by the smart terminal are as follows: the owner sends a start command to the vehicle through the smart terminal that establishes a secure communication link with the vehicle, and the vehicle receives the start command through the T-Box and responds to the start command to start the vehicle. The steps of starting the vehicle specifically include: controlling the main positive relay and the main negative relay of the power battery to close, and / or, starting the engine of the vehicle anti-theft.

[0112] It is understandable that, in the case where it is determined that the T-Box is at risk of being disassembled, there is still a probability that the T-Box has not actually been disassembled. Specifically, there are some minor faults in the T-Box of the vehicle itself, resulting in the first identification code and the second identification code being different from the multiple identification codes corresponding to the power battery. At this time, it is determined that the T-Box is at risk of being disassembled, but the T-Box has not actually been disassembled. The T-Box may still be able to receive and transmit other signals at this time. At this time, in order to ensure that the owner can start the vehicle, it is possible to only restrict the vehicle's power system from being started by local starting methods and dedicated remote controls, and allow the vehicle's power system to be remotely started through an intelligent terminal.

[0113] Alternatively, in some embodiments, two T-Boxes may be installed in the vehicle, one of which is installed more secretly. When the vehicle is stolen, the T-Box in the fixed position is usually removed, while the T-Box in the hidden position can also receive the transmitted data. At this time, in order to ensure that the owner can start the vehicle after finding the vehicle, the vehicle's power system can be restricted from being started by the local start method and the dedicated remote control, and the vehicle's power system can be allowed to be remotely started through the smart terminal.

[0114] In some embodiments, restricting the vehicle's power system from starting may be restricting the vehicle from starting in any way, after which the vehicle may further determine whether the T-Box is disassembled, and if it is determined that the T-Box is not disassembled, the vehicle's power system is allowed to be remotely started via the smart terminal.

[0115] Specifically, if it is determined that the T-Box is at risk of being disassembled, confirmation information on whether the T-Box has been disassembled can be sent to the smart terminal, where the smart terminal is a smart terminal that has passed the vehicle's verification and established a secure communication connection with the vehicle. After checking the confirmation information received by the smart terminal, the owner can actively check whether the vehicle's T-Box has been disassembled, and if it is determined that the T-Box has not been disassembled, send an instruction to the vehicle indicating that the T-Box has not been disassembled, so that after receiving the instruction that the T-Box has not been disassembled, the vehicle determines that the T-Box has not been disassembled and allows the vehicle's power system to be remotely started through the smart terminal.

[0116] In the above method, when it is determined that the T-Box is at risk of being disassembled, the vehicle's power system is allowed to be remotely started through the smart terminal, so that the owner can start the vehicle without the T-BOX being disassembled, avoiding the situation where the vehicle is misjudged as stolen when the T-Box fails, resulting in the vehicle being unable to start and drive.

[0117] In a possible implementation, after restricting the power system of the vehicle from starting, the method further includes: generating and displaying a prompt message, the prompt message being used to inform that the vehicle is at risk of being stolen and the vehicle will not start.

[0118] When it is determined that the T-Box is at risk of being disassembled and the vehicle's power system is restricted from starting, the vehicle can generate a prompt message to inform that the vehicle is at risk of being stolen and the vehicle will not start.

[0119] Specifically, the generated prompt information may be, for example, information such as "the vehicle may be stolen, the vehicle will not start, please contact the 4S store", etc. The generated prompt information may be displayed on the dashboard of the vehicle.

[0120] In some embodiments, after the prompt information is generated, the vehicle may further detect whether there is a smart terminal connected to the vehicle. After determining that there is a smart terminal connected to the vehicle, it is determined based on historical data whether the smart terminal is the smart terminal of the vehicle owner, and if it is determined that the smart terminal is the smart terminal of the vehicle owner, the prompt information is sent to the smart terminal and displayed.

[0121] The smart terminal may be connected to the vehicle via Bluetooth, wireless LAN (Wireless Fidelity, Wi-Fi) or T-Box. As in the above embodiment, there is a probability that the T-Box of the vehicle has not been disassembled, or there may be two T-Boxes in the vehicle, one of which is set more secretly, and the T-Box in the hidden position has not been disassembled. In this case, the vehicle can send the prompt information to the owner's smart terminal through the T-Box and display it.

[0122] In some embodiments, when it is determined that the T-Box of the vehicle is at risk of being disassembled, no absolute restriction is imposed on whether the vehicle enters the parking gear (P gear) (i.e., the vehicle is not forced to enter the P gear) to prevent affecting the vehicle towing, making it easier to repair the vehicle after the T-Box fails or the T-Box is disassembled and retrieved.

[0123] In the above method, after the vehicle power system is restricted from starting, a prompt message is generated to inform that the vehicle is at risk of being stolen and the vehicle will not start. The prompt message can be used as a deterrent to let potential thieves know that the risk of theft has been identified and anti-theft measures have been taken to prevent further illegal behavior by the thieves. The prompt message can also clearly inform the owner that the vehicle will not start after the owner finds the vehicle, so that the owner can send the vehicle to a repair shop for repair in a timely manner.

[0124] In summary, this application determines whether the vehicle's T-Box is at risk of being disassembled by collecting the target signal of the target component uploaded to the cloud by the remote communication terminal within a preset time after determining that the vehicle has stopped running, such as the first identification code of the battery cell with the highest temperature in the power battery, and the status signal of the component that needs to be monitored in an abnormal state. The target signal is specific data in an existing technical setting for monitoring the target component in the vehicle. This method, which relies on the specific data that already exists in the vehicle's monitoring of the target component, determines whether the vehicle is at risk of being stolen. Compared with traditional anti-theft systems, the method is very clever and provides a new anti-theft technology. In the judgment process, it is first determined based on the first identification code whether the T-Box is at risk of being disassembled, and then after the vehicle is started, a second confirmation is performed based on the second identification code to determine whether the T-Box is disassembled to determine whether the vehicle is at risk of being stolen. This secondary confirmation method is more comprehensive, improves the accuracy of judging whether the vehicle is at risk of being stolen, and avoids misjudging the vehicle as being stolen when the vehicle's T-Box is repaired. While restricting the power system from starting, it allows the power system to be started remotely through the smart terminal, so that the owner can start the vehicle without dismantling the T-BOX, avoiding the situation where the T-Box fails and the vehicle is misjudged as stolen, resulting in the vehicle being unable to start and drive.

[0126] For example, Figure 4 As shown, the device 400 includes: The timing module 401 is used to start timing to obtain the timing duration when it is detected that the vehicle stops running; The acquisition module 402 is used to acquire a target signal corresponding to the target component when the timing duration is less than a preset duration; wherein the target signal is a signal uploaded to the cloud by the vehicle's remote communication terminal; A determination module 403 is used to determine whether the remote communication terminal of the vehicle is at risk of being disassembled based on the target signal; The control module 404 is used to restrict the vehicle's power system from starting when it is determined that the remote communication terminal is at risk of being disassembled.

[0129] In one possible implementation, when the target component is a component in a vehicle that needs to be monitored for abnormal conditions, the target signal includes: a status signal of the target component, the preset signal includes a first signal indicating that the target component is normal and a second signal indicating that the target component is abnormal; the judgment module 403 is specifically used to determine whether the status signal is the same as the first signal or the second signal; when the status signal is different from both the first signal and the second signal, it is determined that the remote communication terminal is at risk of being disassembled.

[0130] In one possible implementation, the judgment module 403 is also used to, when the first identification code is different from each of the multiple identification codes corresponding to the power battery, in response to the start of the vehicle, obtain the second identification code of the battery cell with the highest temperature in the current power battery; judge whether the second identification code is the same as any one of the multiple identification codes corresponding to the power battery; and when the second identification code is different from each of the multiple identification codes corresponding to the power battery, determine that the remote communication terminal is at risk of being disassembled.

[0133] In a possible implementation, the device 400 further includes: a prompt module, which is used to generate and display a prompt message after restricting the power system of the vehicle from starting, wherein the prompt message is used to inform that the vehicle is at risk of being stolen and the vehicle will not start.
