Description

Technical Field

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

[0002] As an indispensable means of transportation in daily life, the safety of automobiles has always received extensive attention. Especially for convertible vehicles, due to their structural characteristics, they are more likely to become targets of theft. To address this challenge, vehicle anti-theft technology has evolved from early single means such as mechanical locks, electronic keys, and anti-theft alarms to the current comprehensive solutions integrating multiple technologies.

[0003] Although the early anti-theft technologies could prevent vehicle theft to a certain extent, their anti-theft capabilities were limited and easily cracked. With the development of electronic technology, modern vehicle anti-theft systems have shifted from single mechanical or electronic systems to comprehensive solutions integrating multiple technologies. These solutions may include advanced technologies such as GPS positioning, remote control, and vehicle status monitoring, significantly improving the anti-theft effect of vehicles.

[0004] Despite the significant progress made in modern vehicle anti-theft technology, there are still some deficiencies. Especially when facing the situation where the remote communication terminal is disassembled, the existing anti-theft technologies seem insufficiently comprehensive and reliable. Summary of the Invention

[0005] This application provides a method, device, vehicle, and storage medium for vehicle anti-theft. This method can provide a new anti-theft means, which restricts the power system of the vehicle from starting when the T-Box is disassembled, thereby preventing the vehicle from being illegally driven away, improving the efficiency of the vehicle anti-theft system, and reducing the possibility of vehicle theft.

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

[0007] In the above technical solution, within a preset duration after determining that the vehicle has stopped running, by collecting the target signal of the target component uploaded by the remote communication terminal to the cloud, it is determined whether there is a risk of the remote communication terminal (Telematics Box, T-Box) being disassembled. In the case of determining that there is a risk of the remote communication terminal being disassembled, it is determined that the vehicle has a risk of being stolen, and then the vehicle's power system is restricted from starting, providing a new anti-theft means, enabling the vehicle to timely detect that the vehicle's remote communication terminal may be disassembled within the preset duration after stopping running, and the vehicle has a risk of being stolen. In the case of determining that the vehicle has a risk of being stolen, the vehicle's power system 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 the vehicle being stolen.

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

[0009] In the above technical solution, the target signal is the specific data in an existing technical setting when monitoring the target component in the vehicle. This method of determining whether the vehicle has a risk of being stolen by relying on the specific data that already exists in the vehicle's monitoring of the target component has a higher confidence level compared to traditional anti-theft systems, and the method is very ingenious, providing a new anti-theft technology.

[0010] In combination with the first aspect and the above implementation manners, in some possible implementation manners, when the target component is the power battery, the target signal is the first identification code of the battery cell with the highest temperature in the vehicle's power battery, and the preset signal includes multiple identification codes corresponding to the power battery; determining whether the target signal is the same as the preset signal includes: determining whether the first identification code is the same as any one of the multiple identification codes corresponding to the power battery; where the power battery includes multiple battery cells, and each battery cell corresponds to an identification code; in the case where the target signal is not the same as the preset signal, determining that there is a risk of the remote communication terminal being disassembled includes: in the case where the first identification code is not the same as each of the multiple identification codes corresponding to the power battery, determining that there is a risk of the remote communication terminal being disassembled.

[0011] In the above technical solution, the first identification code is specific data in an existing technical setting for preventing battery fires in a vehicle. 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 there is a risk of theft for the vehicle with the T-Box possibly being disassembled. This method of determining whether there is a risk of vehicle theft relying on the specific data already existing in the vehicle's power battery has a higher confidence level compared to traditional anti-theft systems. The method is very ingenious, and the judgment result is more accurate, enhancing the anti-theft performance of the vehicle.

[0012] Combined with the first aspect and the above implementation, in some possible implementations, when the target component is a component in the vehicle that needs to monitor the abnormal state, the target signal includes: the status signal of the target component, and the preset signals include the first signal indicating the normal state of the target component and the second signal indicating the abnormal state of the target component; 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; in the case where the target signal is different from the preset signal, determining that there is a risk of the remote communication terminal being disassembled includes: in the case where the status signal is different from both the first signal and the second signal, determining that there is a risk of the remote communication terminal being disassembled.

[0013] Combined with the first aspect and the above implementation, in some possible implementations, in the case where the first identification code is different from each of the multiple identification codes corresponding to the power battery, determining that there is a risk of the remote communication terminal being disassembled includes: in the case where the first identification code is different from each of the multiple identification codes corresponding to the power battery, in response to the vehicle starting, 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; in the case where the second identification code is different from each of the multiple identification codes corresponding to the power battery, determining that there is a risk of the remote communication terminal being disassembled.

[0014] In the above technical solution, first, based on the fact that the first identification code is different from each of the multiple identification codes corresponding to the power battery, it is determined that there is a risk of the T-Box being disassembled. After the vehicle starts, the second identification code is obtained, and based on the second identification code, it is secondarily confirmed whether the T-Box is disassembled. In the case where the second identification code is different from each of the multiple identification codes corresponding to the power battery, it is again determined that there is a risk of the T-Box being disassembled, and then it is determined that there is a risk of vehicle theft. This method of secondary confirmation is more comprehensive, improves the accuracy of determining the risk of vehicle theft, and avoids misjudging the vehicle as stolen when repairing the vehicle's T-Box.

[0015] Combined with the first aspect and the above implementation manners, in some possible implementation manners, when it is determined that there is a risk of the remote communication terminal being disassembled, restricting the vehicle's power system from starting includes: when it is determined that there is a risk of the remote communication terminal being disassembled, detecting the states of the power battery and the vehicle's engine; when the main positive relay and / or the main negative relay of the power battery is in an open state and the engine is in a flameout state, restricting the vehicle's power system from starting.

[0016] Combined with the first aspect and the above implementation manners, in some possible implementation manners, when it is determined that there is a risk of the remote communication terminal being disassembled, the method further includes: allowing the vehicle's power system to be remotely started through the intelligent terminal.

[0017] In the above technical solution, when it is determined that there is a risk of the T-Box being disassembled, allowing the vehicle's power system to be remotely started through the intelligent terminal enables the vehicle owner to start the vehicle when the T-BOX is not disassembled, avoiding the situation where the vehicle cannot be started and driven due to misjudging the vehicle as stolen when the T-Box has a fault.

[0018] In summary, within a preset duration after the vehicle stops running, the present application collects the target signals of the target components uploaded by the remote communication terminal to the cloud, such as the first identification code of the battery cell with the highest temperature of the power battery, and the status signals of the components that need to monitor abnormal states, to determine whether there is a risk of the vehicle's T-Box being disassembled. The target signal is the specific data in a technical setting existing for monitoring the target components in the vehicle. This method of judging whether the vehicle has a risk of being stolen by relying on the specific data existing in the vehicle's monitoring of the target components itself has a higher confidence level than the traditional anti-theft system, and the method is very ingenious, providing a new anti-theft technology. During the judgment process, first, based on the first identification code, it is determined that there is a risk of the T-Box being disassembled, and then after the vehicle starts, based on the second identification code, a secondary confirmation is made to determine whether the T-Box is disassembled, so as to determine whether the vehicle has a risk of being stolen. This method of secondary confirmation is more comprehensive, improving the accuracy of judging that the vehicle has a risk of being stolen and avoiding misjudging the vehicle as stolen when repairing the vehicle's T-Box. Restricting the start of the power system while allowing the power system to be remotely started through the intelligent terminal enables the vehicle owner to start the vehicle when the T-BOX is not disassembled, avoiding the situation where the vehicle cannot be started and driven due to misjudging the vehicle as stolen when the T-Box has a fault.

[0021] In combination with the second aspect and the above implementation manners, in some possible implementation manners, when the target component is a power battery, the target signal is a first identification code of the battery cell with the highest temperature in the power battery of the vehicle, and the preset signal includes a plurality of identification codes corresponding to the power battery; the determination module is specifically configured to determine whether the first identification code is the same as any one of the plurality of identification codes corresponding to the power battery, where the power battery includes a plurality of battery cells and each battery cell corresponds to an identification code; and determine that there is a risk that the remote communication terminal is disassembled when the first identification code is not the same as each of the plurality of identification codes corresponding to the power battery.

[0022] In combination with the second aspect and the above implementation manners, in some possible implementation manners, when the target component is a component in the vehicle that needs to monitor an abnormal state, the target signal includes: a state signal of the target component, and 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 determination module is specifically configured to determine whether the state signal is the same as the first signal or the second signal; and determine that there is a risk that the remote communication terminal is disassembled when the state signal is not the same as both the first signal and the second signal.

[0023] In combination with the second aspect and the above implementation manners, in some possible implementation manners, the determination module is further configured to, when the first identification code is not the same as each of the plurality of identification codes corresponding to the power battery, in response to the vehicle starting, obtain a second identification code of the battery cell with the highest temperature in the current power battery; determine whether the second identification code is the same as any one of the plurality of identification codes corresponding to the power battery; and determine that there is a risk that the remote communication terminal is disassembled when the second identification code is not the same as each of the plurality of identification codes corresponding to the power battery.

[0024] Combined with the second aspect and the above implementation manners, in some possible implementation manners, the control module is specifically configured to detect the states of the power battery and the vehicle's engine when it is determined that there is a risk of the remote communication terminal being disassembled; when the main positive relay and / or the main negative relay of the power battery is in an open state and the engine is in a flameout state, restrict the vehicle's power system from starting.

[0025] Combined with the second aspect and the above implementation manners, in some possible implementation manners, the device further includes: an allow - start module, configured to allow the vehicle's power system to be remotely started through the intelligent terminal when it is determined that there is a risk of the remote communication terminal being disassembled.

[0034] The technical solutions in the present application will be clearly and elaborately described below in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may represent A or B. The "and / or" in the text is only a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality of" means two or more than two.

[0035] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0036] As global environmental problems 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 achieve the effect of reducing fuel consumption but also reduce emissions. Therefore, hybrid vehicles will become the mainstream of the automotive industry's development in the future for a long time.

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

[0038] As an indispensable means of transportation in daily life, the safety of automobiles has always received extensive attention. Hybrid vehicles include both the engines of pure gasoline vehicles and the high-voltage systems of pure electric vehicles. The anti-theft technology for hybrid vehicles can be applied to both pure gasoline vehicles and pure electric vehicles. Although significant progress has been made in modern anti-theft technology for hybrid vehicles, there are still some deficiencies. Especially when faced with the situation where the remote communication terminal is disassembled, the existing anti-theft technology appears to be insufficiently comprehensive and reliable.

[0039] Based on this, the present application proposes a method for vehicle anti-theft, providing a new anti-theft means, enabling the vehicle to promptly detect the risk of theft based on the first identification code within a preset duration after stopping operation, and restricting the power system from starting in the event of a theft risk, 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 flowchart of a vehicle anti-theft method provided by an embodiment of the present application.

[0041] Exemplarily, as Figure 1 shown, the method 100 includes:

[0042] Step 101, when it is detected that the vehicle stops running, start timing to obtain a timing duration;

[0043] Step 102, when the timing duration is less than a preset duration, collect a target signal corresponding to a target component;

[0044] Wherein, the target signal is a signal uploaded by the vehicle's remote communication terminal to the cloud.

[0045] Step 103, based on the target signal, determine whether there is a risk that the vehicle's remote communication terminal is disassembled;

[0046] Step 104, when it is determined that there is a risk that the remote communication terminal is disassembled, restrict the vehicle's power system from starting.

[0047] In Figure 1 the shown embodiment, within a preset duration after it is determined that the vehicle stops running, by collecting the target signal of the target component uploaded by the remote communication terminal to the cloud, determine whether there is a risk that the vehicle's remote communication terminal (Telematics Box, T-Box) is disassembled. When it is determined that there is a risk that the remote communication terminal is disassembled, determine that the vehicle is at risk of being stolen, and then restrict the vehicle's power system from starting, providing a new anti-theft means, enabling the vehicle to timely detect that the vehicle's remote communication terminal may be disassembled based on the target signal within a preset duration after stopping running, and the vehicle is at risk of being stolen. When it is determined that the vehicle is at risk of being stolen, timely restrict the vehicle's power system 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.

[0048] Next, a detailed description of the specific implementation manners of each step in Figure 1 the shown embodiment is provided:

[0049] In step 101, the vehicle stopping running means that the vehicle's power system (such as an engine or a motor) no longer provides power, and the vehicle is in a stationary state. At this time, the user usually gets out of the vehicle and parks the vehicle at the current location for a certain duration, and the vehicle will be in a state of unattended parking and parking, and the vehicle is prone to the risk of being stolen, especially for convertible vehicles, there is a risk of stealing the vehicle after the T-Box is disassembled.

[0050] A vehicle includes a low-voltage system responsible for powering various vehicle and auxiliary systems in the vehicle. After determining that the vehicle has stopped running, the low-voltage system of the vehicle usually still operates for a certain period of time, and a timer may be included in the low-voltage system. When it is determined that the vehicle has stopped running, the timer starts timing to obtain the timing duration.

[0051] In one possible implementation, the method further includes: determining that the vehicle has stopped running when it is detected that the main positive relay and / or the main negative relay of the power battery is / are disconnected, and / or when it is detected that the engine of the vehicle has stalled.

[0052] Among them, the vehicle may specifically be a hybrid vehicle. A hybrid vehicle includes a power battery, and in some embodiments, the power battery is also referred to as a high-voltage battery. The power battery supplies power to the motor to make the motor rotate, and the motor outputs power to drive the vehicle to travel.

[0053] Figure 2 It is a schematic circuit diagram of a power battery driving a motor provided by an embodiment of the present application.

[0054] Exemplarily, as Figure 2 shown, it includes: a power battery 201, a main positive relay 202, a main negative relay 203, and a motor 204.

[0055] Among them, 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 it is necessary for the power battery 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, and the motor 204 rotates to output power to drive the vehicle to travel.

[0056] In some embodiments, the circuit further includes a pre-charge resistor 205 and a pre-charge relay 206. When the high-voltage battery starts to discharge, the pre-charge relay 206 first closes, and the current flows through the pre-charge resistor 205 to the motor 204. The motor is gradually charged, and the current gradually increases. When the motor is fully charged, the pre-charge relay disconnects, and the pre-charge resistor exits the circuit. The main positive relay closes, and the high-voltage battery is directly connected to the motor, and the motor starts to operate normally. This process ensures the smooth start of the motor, reduces the impact on the motor and its related components, and extends their service life.

[0057] When the vehicle uses the power battery to output power, it is possible to detect whether the main positive relay and / or the main negative relay of the power battery is / are disconnected from the closed state. When it is detected that the main positive relay and / or the main negative relay of the power battery is / are disconnected, it is determined that the vehicle has stopped running.

[0058] 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 to travel. When the vehicle uses the engine to output power, it is possible to detect whether the engine stalls from the running state. In the case where it is detected that the engine stalls from the running state, it is determined that the vehicle stops running.

[0059] When the vehicle is driven by the combined 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 is disconnected from the closed state and whether the engine stalls from the running state. In the case where it is detected that the main positive relay and / or the main negative relay of the power battery is disconnected from the closed state and the engine stalls from the running state, it is determined that the vehicle stops running.

[0060] In step 102, the preset duration can be the delay working duration of the low-voltage system in the vehicle after the vehicle stops running.

[0061] It can be understood that immediately cutting off the low-voltage system after the vehicle stops running may cause some important safety functions to fail to work properly. Most vehicle systems need time to complete data saving, system resetting, or shutdown processes after the vehicle stops running. To meet the requirements of safety and system resetting, the low-voltage system will be delayed for a certain duration before shutting down after the vehicle stops running.

[0062] The target signal corresponding to the target component can specifically be: a signal that the vehicle needs the remote communication terminal to upload to the cloud in real time or based on a relatively small preset period (such as 1 s, 2 s) so that the cloud can monitor the signal of the target component in the vehicle. 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 within the preset duration.

[0063] Specifically, a power system control device can be set in the vehicle. After it is determined that the vehicle stops running, the low-voltage system supplies power to the power system control device so that the power system control device can collect the target signal corresponding to the target component uploaded to the cloud by the remote communication terminal within the preset duration.

[0064] The target components can include components such as the power battery, engine, motor, and exhaust pipe of the vehicle. The target signal is the signal corresponding to any one of the components such as the power battery, engine, motor, and exhaust pipe that needs to be uploaded to the cloud by the remote communication terminal in real time or based on a relatively small preset period.

[0065] In step 103, if the target signal is the data that the collected T-Box is about to upload to the cloud, the state of the T-Box can be determined based on the first standard signal. Specifically, based on the target signal, it can be determined whether the T-Box is disassembled. Based on whether the T-Box is disassembled, it can be determined whether the vehicle has a theft risk. Generally, in the case where it is determined that the T-Box is disassembled, it is determined that the vehicle has a theft risk.

[0066] It is understandable that the T-Box is an important component in a vehicle and is usually used to implement remote communication and vehicle status monitoring functions. It uploads the vehicle's status information to a cloud server through wireless communication technologies (such as cellular networks) and provides the following functions: Remote monitoring: Real-time monitoring of the vehicle's location, speed, battery status, etc. Anti-theft function: Helps confirm whether the vehicle has been stolen through location tracking and status monitoring. Remote diagnosis: Uploads the vehicle's fault information for remote diagnosis and maintenance. Remote control: Allows operations such as remote starting, locking / unlocking the vehicle, etc.

[0067] If the T-Box in the vehicle is disassembled, it means that the vehicle's status information cannot be uploaded to the cloud server, resulting in the failure of the vehicle monitoring function. The vehicle cannot locate and track its position, the anti-theft function of the vehicle fails, and it increases the difficulty of retrieving the stolen vehicle. Therefore, thieves usually disassemble the vehicle's T-Box to avoid being tracked when stealing a car, making the vehicle easier to be stolen. It is possible to determine whether there is a risk of vehicle theft based on whether the T-Box has been disassembled.

[0068] Figure 3 It is a schematic diagram of T-Box power management provided by an embodiment of the present application.

[0069] Exemplarily, as Figure 3 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.

[0070] Specifically, it includes: converting the 12V power into 5V power for the vehicle's Controller Area Network (CAN) communication. Converting the 12V power into 3.8V power for the General Packet Radio Service (GPRS) module to conduct information communication. GPRS is an early mobile data communication technology used for data transmission between the T-Box and an external network (such as a cellular network). Converting the 12V power into 3.3V power, which is mainly supplied to the single-chip microcomputer and other auxiliary circuits, such as the watchdog timer. The single-chip microcomputer is the core processor of the T-Box, and the watchdog is a hardware protection mechanism used to monitor and recover possible faults of the single-chip microcomputer.

[0071] In a possible implementation manner, based on the target signal, it is determined whether there is a risk that the remote communication terminal of the vehicle is disassembled, including: determining whether the target signal is the same as the preset signal; wherein, the preset signal is the signal corresponding to the target component uploaded to the cloud when the communication terminal is not disassembled; in the case where the target signal is not the same as the preset signal, it is determined that there is a risk that the remote communication terminal is disassembled.

[0072] 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.

[0073] 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 both the default signal or the error signal are not the same as the preset signal of the target component. Therefore, after the target signal corresponding to the target component is collected, it can be determined whether the target signal is the same as the preset signal corresponding to the target component. In the case where it is determined that the target signal is different from the preset signal, it can be determined that there is a risk that the communication terminal is disassembled.

[0074] In the above method, the target signal is the specific data in an existing technical setting when monitoring the target component in the vehicle. This method of judging whether the vehicle has a theft risk based on the specific data that already exists in the vehicle's monitoring of the target component itself has a higher confidence level compared to traditional anti-theft systems. The method is very ingenious and provides a new anti-theft technology.

[0075] In a possible implementation manner, when the target component is the power battery, the target signal is the first identification code of the battery cell with the highest temperature in the vehicle's power battery, and the preset signal includes multiple identification codes corresponding to the power battery; determining whether the target signal is the same as the preset signal includes: determining 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; in the case where the target signal is not the same as the preset signal, determining that there is a risk that the remote communication terminal is disassembled includes: in the case where the first identification code is not the same as each of the multiple identification codes corresponding to the power battery, determining that there is a risk that the remote communication terminal is disassembled.

[0076] When the target component is a power battery, the target signal may specifically include: the first identification code of the battery cell with the highest temperature in the power battery of the vehicle.

[0077] Among them, the identification code refers to an identifier used to uniquely identify each independent battery cell in the power battery, and may specifically be a numerical value. The power battery (i.e., the high-voltage battery) is an integrated module composed of multiple groups of small batteries, and each small battery group or small battery can be referred to as a battery cell.

[0078] To prevent the battery from catching fire due to excessive temperature, the temperature of each battery cell is collected, and the identification code of the battery cell with the highest temperature is uploaded to the cloud by the T-Box. The system control device can collect in real time the identification code of the battery cell with the highest temperature that is about to be uploaded to the cloud in the T-Box to obtain the first identification code.

[0079] The power battery includes multiple groups of small batteries or multiple small batteries, and each small battery group or small battery can be referred to as 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 all different.

[0080] Exemplarily, the power battery includes 254 groups of small batteries, that is, the power battery includes 254 independent battery cells, and the identification codes of each battery cell can be the numbers 1 to 254 in sequence. There is a battery cell with the highest temperature in the power battery, and the identification code of this 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 is collected by the T-Box and about to be uploaded to the cloud should be any one of the numbers 1 to 254.

[0081] It can be understood that any one of the battery cells in the power battery may be the battery cell with the highest temperature, that is to say, the identification code of any one of the battery cells 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 the battery cells included in the power battery.

[0082] 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. The default value or error value is different from the identification codes of 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 there is a risk of the T-Box being disassembled, that is, it is determined that the vehicle is at risk of being stolen.

[0083] 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 within the range of numbers 1 to 254. When it is determined that the first identification code is not within the range of numbers 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 there is a risk of the T-Box being disassembled, and also that the vehicle is at risk of being stolen.

[0084] In the above method, the first identification code is the specific data in a technical setting already existing in the vehicle to prevent battery fire. By comparing the first identification code with the 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 being stolen. This method of determining whether the vehicle is at risk of being stolen by relying on the specific data already existing in the vehicle's power battery has a higher confidence level than traditional anti-theft systems, is very ingenious, and the judgment result is more accurate, enhancing the anti-theft performance of the vehicle.

[0085] In a possible implementation manner, when it is determined that there is a risk of the remote communication terminal being disassembled in the case where the first identification code is different from each of the multiple identification codes corresponding to the power battery, it includes: when the first identification code is different from each of the multiple identification codes corresponding to the power battery, in response to the vehicle starting, 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; and when the second identification code is different from each of the multiple identification codes corresponding to the power battery, determining that there is a risk of the remote communication terminal being disassembled.

[0086] When it is determined that each of the multiple identification codes corresponding to the power battery is different from the first identification code, it can be determined that the T-Box has been removed after the vehicle stops running. Based on this, it can be preliminarily determined that the vehicle is at risk of being stolen. To further determine whether the vehicle is at risk of being stolen, when it is preliminarily determined that the vehicle is at risk of being stolen, in response to the vehicle starting again, the second identification code of the battery cell with the highest temperature in the power battery can be obtained again. Determine whether the second identification code is the same as any one of the multiple identification codes corresponding to the power battery to determine whether the T-Box has actually been removed, that is, determine whether the T-Box has been reinstalled before the vehicle starts, and further determine whether the vehicle is at risk of being stolen.

[0087] Among them, the power system control device can determine that the vehicle starts again when it detects that the vehicle's engine starts and / or the main positive relay and the main negative relay of the power battery are closed.

[0088] It can be understood that there is a situation where the vehicle repairs the T-Box. The maintenance personnel may remove the vehicle's T-Box for corresponding maintenance within a preset time period and reinstall the T-Box back to the vehicle after the preset time period. At this time, although each of the first identification codes obtained within the preset time period after stopping running is different from each of the multiple identification codes corresponding to the power battery. After the T-Box is reinstalled back to the vehicle, the second identification code obtained when the vehicle starts again 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 removed, and the vehicle is not at risk of being stolen.

[0089] When the second identification code obtained after the vehicle starts 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 has been removed after the vehicle stops running and the T-Box has not been reinstalled back to the vehicle when the vehicle starts again. At this time, it can be determined that the vehicle is at risk of being stolen.

[0090] In the above method, first, based on the fact that each of the first identification codes 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 removed. After the vehicle starts, the second identification code is obtained. Based on the second identification code, it is confirmed again whether the T-Box has been removed. 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 removed, and then it is determined that the vehicle is at risk of being stolen. This method of double confirmation is more comprehensive, improves the accuracy of judging the risk of vehicle theft, and avoids misjudging the vehicle as stolen when repairing the vehicle's T-Box.

[0091] In a possible implementation, when the target component is a component in a vehicle that needs to monitor abnormal states, the target signal includes: the state signal of the target component, and the preset signals include 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 state signal is the same as the first signal or the second signal; in the case where the target signal is not the same as the preset signal, determining that there is a risk that the remote communication terminal has been disassembled includes: in the case where the state signal is not the same as both the first signal and the second signal, determining that there is a risk that the remote communication terminal has been disassembled.

[0092] Components in a vehicle that need to be monitored for abnormal states in real time may specifically include: components such as engines, motors, and exhaust pipes. When the target component is an engine, the state signal may specifically be a state signal indicating whether the engine emission parameters are normal. When the target component is a motor, the state signal may specifically be a state signal indicating whether the motor is operating normally. When the target component is an exhaust pipe, the state signal may specifically be a state signal indicating whether the particulate trap in the exhaust pipe is normal.

[0093] In some embodiments, components in a vehicle that need to be monitored for abnormal states in real time may further include a power battery. When the target component is a power battery, the state signal may specifically be a state signal indicating whether the voltage or current of the power battery is normal.

[0094] It can be understood that there are some target components in a vehicle that need to monitor or predict whether the state of the target component is abnormal in real time, so as to prompt the user in time when it is monitored or predicted that the target component is abnormal, so that the user can perform corresponding operations based on the prompt to ensure the driving safety of the vehicle.

[0095] When the T-Box has not been disassembled, when the target component is normal, the T-Box needs to upload the first signal indicating that the target component is normal to the cloud. When the target component is abnormal, the T-Box needs to upload the second signal indicating that the component is abnormal to the cloud.

[0096] Exemplarily, the target component is a power battery, and the state 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 the normal range (for example, between 3.0V and 4.2V), the T-Box uploads the first signal indicating that the voltage of the power battery is normal to the cloud, such as 0. When there is a battery cell of the power battery whose voltage is not within the normal range (for example, between 3.0V and 4.2V), the T-Box uploads the second signal indicating that the voltage of the power battery is abnormal to the cloud, such as 1.

[0097] It is understandable that the target component may be in a normal state or an abnormal state. That is to say, when the T-Box is not disassembled, it may upload a first signal or a second signal to the cloud. Therefore, the preset signals include a first signal indicating the normal state of the target component and a second signal indicating the abnormal state of the target component.

[0098] 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 error signal is different from the first signal or 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 indicating the normal state of the component and the second signal indicating the abnormal state of the component. When it is determined that the status signal is different from both the first signal and the second signal, it is determined that there is a risk of the T-Box being disassembled, that is, it is determined that the vehicle is at risk of being stolen.

[0099] Exemplarily, the default signal or error signal is, for example, other signals 2, 3, 4, etc. outside 0 and 1. After obtaining the status signal of the power battery, it can be determined whether the status signal is the same as the signal 0 indicating the normal voltage of the power battery or the signal 1 indicating the abnormal voltage of the power battery. When the status signal of the power battery is neither 0 nor 1, it is determined that there is a risk of the T-Box being disassembled, that is, the vehicle is at risk of being stolen.

[0100] 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 the T-Box to the cloud is the first signal indicating the normal state of the engine. When the emission parameters of the engine are not within the qualified range, the status signal uploaded by the T-Box to the cloud is the second signal indicating the abnormal state of the engine. When the component is a motor, when the predicted reliability of the motor is greater than or equal to a preset reliability (for example, 80%), the status signal uploaded by the T-Box to the cloud is the first signal indicating the normal state of the motor. When the predicted reliability of the motor is less than the preset reliability (for example, 80%), the status signal uploaded by the T-Box to the cloud is the second signal indicating the abnormal state of the motor. When the component is an exhaust pipe, when the particulate trap in the exhaust pipe is not disassembled, the status signal uploaded by the T-Box to the cloud is the first signal indicating the normal state of the exhaust pipe. When the particulate trap in the exhaust pipe is disassembled, the status signal uploaded by the T-Box to the cloud is the second signal indicating the abnormal state of the exhaust pipe.

[0101] 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 the 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 the preset pressure difference.

[0102] The process of determining whether the T-Box is removed based on the status signal of any one of the above-mentioned engine, motor, and exhaust pipe is similar to the process of determining whether the T-Box is removed based on the status signal of the power battery voltage, and will not be elaborated here.

[0103] It can be understood that the status signal corresponding to the above target component is recorded as the first status signal. When determining whether the T-Box is removed based on the first status signal, if it is detected that the vehicle starts 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 starts can be obtained, and it is determined again whether the second status signal is the same as the first signal representing the normal state of the target component and the second signal representing the abnormal state. When it is determined that the second status signal is different from both the first signal and the second signal, it is determined that there is a risk that the remote communication terminal has been removed.

[0104] In step 104, restricting the vehicle's power system from starting may include: controlling the vehicle not to execute the main positive relay and / or main negative relay closing command; controlling the vehicle not to execute the engine start command either, so as to prevent the stolen vehicle from driving by itself and prevent the vehicle from being stolen.

[0105] In a possible implementation, when it is determined that there is a risk that the remote communication terminal has been removed, restricting the vehicle's power system from starting includes: when it is determined that there is a risk that the remote communication terminal has been removed, detecting the status of the power battery and the vehicle's engine; when the main positive relay and / or main negative relay of the power battery is in the off state and the engine is in the off state, restricting the vehicle's power system from starting.

[0106] After the vehicle is restarted, when it is determined based on the second identification code that there is a risk that the T-Box has been removed and there is a risk that the vehicle has been stolen, it is highly likely that the vehicle has been stolen. At this time, it is necessary to restrict the vehicle's power system from starting while ensuring the safety of the vehicle.

[0107] It can be understood that when the vehicle is in the starting state, the main positive relay and main negative relay of the vehicle's power battery are in the closed state and / or the engine is in the running state, directly restricting the vehicle's power system from starting is likely to cause vehicle safety problems.

[0108] Specifically, the status of the main positive relay, main negative relay of the vehicle's high-voltage battery, and the engine can be monitored. After the main positive relay and 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.

[0109] As in the above embodiments, restricting the vehicle's powertrain from starting can include: controlling the vehicle to no longer execute the main positive relay and / or main negative relay closing commands; controlling the vehicle to no longer execute the engine start command, so as to prevent the stolen vehicle from driving itself and prevent the vehicle from being stolen.

[0110] In some embodiments, the vehicle starting methods can include two types: local start and remote start.

[0111] Among them, local start refers to an operation performed inside the vehicle or directly through the vehicle's own control system to start the vehicle's powertrain. Local start specifically includes: Traditional key start: Insert a metal key into the ignition switch and rotate to start the engine. Keyless start (push-button start): Enter the vehicle with a key carrying a wireless transmitter and press the start button to start the engine. Touchscreen start: In some high-end models, start the engine through virtual buttons on the in-vehicle touchscreen interface. Voice start: Start the vehicle through voice commands.

[0112] Remote start refers to the process of starting the vehicle through non-contact remote communication means. Specifically includes: Starting through applications on terminals such as smartphones and tablets: Send a start instruction through an application on a smartphone, tablet and other terminals to start the vehicle; Starting with a dedicated remote control: Use the dedicated remote control equipped with the vehicle to start the vehicle within a certain range.

[0113] Since users may leave the vehicle's dedicated remote control and key inside the vehicle, when the vehicle is stolen, the thief can not only start the vehicle through the above local start methods, but also remotely start the vehicle with the dedicated remote control. Therefore, restricting the vehicle's powertrain from starting specifically includes: restricting the vehicle's powertrain from starting through local start methods and dedicated remote controls.

[0114] In one possible implementation, when it is determined that there is a risk of the T-Box being disassembled, the method further includes: allowing the vehicle's powertrain to be remotely started through a smart terminal.

[0115] Among them, the smart terminal can specifically be a mobile phone, tablet, smart bracelet and other smart terminals that have passed the vehicle's verification and established a secure communication connection with the vehicle.

[0116] The steps for remotely starting the vehicle with a smart terminal are: The vehicle owner sends a start instruction to the vehicle through a smart terminal that has established a secure communication connection with the vehicle, and the vehicle receives the start through the T-Box and responds to the start instruction to start the vehicle. The steps for starting the vehicle specifically include: controlling the main positive relay and main negative relay of the power battery to close, and / or, starting the engine for vehicle anti-theft.

[0117] It can be understood that when it is determined that there is a risk of the T-Box 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, resulting in the situation where both the first identification code and the second identification code are different from the multiple identification codes corresponding to the power battery. At this time, it is determined that there is a risk of the T-Box 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 vehicle owner can start the vehicle, the power system of the vehicle can be restricted from starting through the local start method and the dedicated remote control, and the power system of the vehicle is allowed to start remotely through the intelligent terminal.

[0118] Alternatively, in some embodiments, there may be two T-Boxes in the vehicle. One of the T-Boxes is set in a relatively concealed position. When the vehicle is stolen, the T-Box in the fixed position is usually disassembled, and the T-Box in the concealed position can still receive and transmit data. At this time, in order to ensure that the vehicle owner can start the vehicle after retrieving the vehicle, the power system of the vehicle can be restricted from starting through the local start method and the dedicated remote control, and the power system of the vehicle is allowed to start remotely through the intelligent terminal.

[0119] In some embodiments, restricting the power system of the vehicle from starting may mean restricting the vehicle from starting in any way. Then, the vehicle can further determine whether the T-Box has been disassembled. When it is determined that the T-Box has not been disassembled, the power system of the vehicle is allowed to start remotely through the intelligent terminal.

[0120] Specifically, when it is determined that there is a risk of the T-Box being disassembled, a confirmation message indicating whether the T-Box has been disassembled can be sent to the intelligent terminal, where the intelligent terminal is an intelligent terminal that has passed the verification of the vehicle and established a secure communication link with the vehicle. When the vehicle owner views the confirmation message received by the intelligent terminal, the vehicle owner can actively check whether the T-Box of the vehicle has been disassembled. When it is determined that the T-Box has not been disassembled, a command indicating that the T-Box has not been disassembled is sent to the vehicle, so that after the vehicle receives the command indicating that it has not been disassembled, it is determined that the T-Box has not been disassembled, and the power system of the vehicle is allowed to start remotely through the intelligent terminal.

[0121] In the above method, when it is determined that there is a risk of the T-Box being disassembled, the power system of the vehicle is allowed to start remotely through the intelligent terminal, enabling the vehicle owner to start the vehicle when the T-BOX has not been disassembled, and avoiding the situation where the vehicle cannot be started and driven due to misjudging that the vehicle has been stolen when the T-Box has a fault.

[0122] In a possible implementation manner, after restricting the power system of the vehicle from starting, the method further includes: generating and displaying a prompt message, where the prompt message is used to inform that there is a risk of the vehicle being stolen and the vehicle will not start.

[0123] When it is determined that there is a risk of the T-Box being disassembled and the vehicle's power system is restricted from starting, the vehicle can generate a prompt message to inform that there is a risk of the vehicle being stolen and the vehicle will not start.

[0124] Specifically, the generated prompt message can be, for example, "The vehicle may have been stolen and this vehicle will not start. Please contact the 4S store" and other information. The generated prompt message can be displayed on the vehicle's dashboard.

[0125] In some embodiments, after generating the prompt message, the vehicle can also detect whether there is a smart terminal connected to the vehicle. After determining that there is a smart terminal connected to the vehicle, based on historical data, it is determined whether the smart terminal is the vehicle owner's smart terminal, and when it is determined that the smart terminal is the vehicle owner's smart terminal, the prompt message is sent to and displayed on the smart terminal.

[0126] Among them, the smart terminal can be connected to the vehicle through Bluetooth, Wireless Fidelity (Wi-Fi), or the T-Box. As in the above embodiments, there is a probability that the vehicle's T-Box is actually not disassembled, or there may be two T-Boxes installed in the vehicle, and one of the T-Boxes is set in a relatively hidden position and the T-Box in the hidden position is not disassembled. In this case, the vehicle can send the prompt message to and display it on the vehicle owner's smart terminal through the T-Box.

[0127] In some embodiments, when it is determined that there is a risk of the vehicle's T-Box being disassembled, there is no absolute restriction on whether the vehicle enters the parking gear P gear (that is, it does not force the vehicle to enter the P gear) to prevent affecting vehicle towing and facilitate vehicle maintenance after the T-Box fails or the T-Box is disassembled and the vehicle is retrieved.

[0128] In the above method, after restricting the vehicle's power system from starting, a prompt message is generated to inform that there is a risk of the vehicle being stolen and the vehicle will not start. The prompt message can be used as a deterrent means to let potential thieves know that the vehicle has recognized the risk of theft and has taken anti-theft measures to prevent further illegal acts by the thieves. The prompt message can also clearly inform the vehicle owner that the vehicle will not start after the vehicle owner retrieves the vehicle, facilitating the vehicle owner to send the vehicle to the repair shop for maintenance in a timely manner.

[0129] In summary, within a preset duration after determining that the vehicle has stopped running, by collecting the target signals of the target components uploaded by the remote communication terminal to the cloud, such as the first identification code of the battery cell with the highest power battery temperature, and the status signals of the components that need to monitor abnormal status, to determine whether there is a risk that the vehicle's T-Box has been disassembled. The target signal is the specific data in a technical setting for monitoring the target components in the vehicle. This method of determining whether the vehicle has a theft risk based on the specific data that already exists in the vehicle's monitoring of the target components has a higher confidence level compared to traditional anti-theft systems. The method is very ingenious and provides a new anti-theft technology. During the judgment process, first, based on the first identification code, it is determined that there is a risk that the T-Box has been disassembled, and then after the vehicle is started, based on the second identification code, a secondary confirmation is made to determine whether the T-Box has been disassembled, so as to determine whether the vehicle has a theft risk. This method of secondary confirmation is more comprehensive, improves the accuracy of judging that the vehicle has a theft risk, and avoids misjudging that the vehicle has been stolen when repairing the vehicle's T-Box. While restricting the start of the power system, it allows the power system to be remotely started through the intelligent terminal, enabling the vehicle owner to start the vehicle when the T-BOX has not been disassembled, and avoiding the situation where the vehicle cannot be started and driven due to misjudging that the vehicle has been stolen when the T-Box has a fault.

[0130] Figure 4 It is a schematic structural diagram of a vehicle anti-theft device provided by an embodiment of the present application.

[0131] Exemplarily, as Figure 4 shown, the device 400 includes:

[0132] A timing module 401, configured to start timing to obtain a timing duration when it is detected that the vehicle has stopped running;

[0134] A judgment module 403, configured to judge whether there is a risk that the remote communication terminal of the vehicle has been disassembled based on the target signal;

[0135] A control module 404, configured to restrict the power system of the vehicle from starting when it is determined that there is a risk that the remote communication terminal has been disassembled.

[0136] In a possible implementation manner, the judgment module 403 is specifically configured to judge whether the target signal is the same as the preset signal; wherein, the preset signal is the signal corresponding to the 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 there is a risk that the remote communication terminal has been disassembled.

[0137] In a 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 vehicle's power battery, and the preset signals include multiple identification codes corresponding to the power battery; the determination module 403 is specifically configured 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, and each battery cell corresponds to an identification code; in the case where the first identification code is not the same as each of the multiple identification codes corresponding to the power battery, it is determined that there is a risk that the remote communication terminal has been disassembled.

[0138] In a possible implementation, when the target component is a component in the vehicle that needs to monitor the abnormal state, the target signal includes: the status signal of the target component, and the preset signals include the first signal indicating that the target component is normal and the second signal indicating that the target component is abnormal; the determination module 403 is specifically configured to determine whether the status signal is the same as the first signal or the second signal; in the case where the status signal is not the same as both the first signal and the second signal, it is determined that there is a risk that the remote communication terminal has been disassembled.

[0139] In a possible implementation, the determination module 403 is further configured to, in the case where the first identification code is not the same as each of the multiple identification codes corresponding to the power battery, in response to the vehicle starting, obtain the second identification code of the battery cell with the highest temperature in the current power battery; determine whether the second identification code is the same as any one of the multiple identification codes corresponding to the power battery; in the case where the second identification code is not the same as each of the multiple identification codes corresponding to the power battery, it is determined that there is a risk that the remote communication terminal has been disassembled.

[0140] In a possible implementation, the control module 404 is specifically configured to, in the case where it is determined that there is a risk that the remote communication terminal has been disassembled, detect the status of the power battery and the vehicle's engine; in the case where the main positive relay and / or the main negative relay of the power battery is in the off state and the engine is in the off state, restrict the vehicle's power system from starting.

[0141] In a possible implementation, the device 400 further includes: an allow - start module, configured to, in the case where it is determined that there is a risk that the remote communication terminal has been disassembled, allow the vehicle's power system to be remotely started through the intelligent terminal.

[0142] In a possible implementation, the device 400 further includes: a prompt module, configured to, after restricting the vehicle's power system from starting, generate and display a prompt message, and the prompt message is used to inform that there is a risk of vehicle theft and the vehicle will not start.

[0143] Figure 5 It is a schematic structural diagram of a vehicle provided by an embodiment of the present application.
