Description

Technical Field

[0001] This application relates to the field of automotive safety, specifically to a vehicle anti-theft control method, system, device, and computer-readable storage medium. Background Technology

[0002] With the rapid development of the new energy vehicle industry and the continuous increase in the popularity of electric vehicles, high-voltage power components (such as power batteries, drive motors, and high-voltage power distribution units) have gradually become the main targets of theft by criminals due to their high manufacturing costs and high resale value. Therefore, how to effectively monitor the safety status of high-voltage power components has become an urgent need to be addressed in the field of vehicle anti-theft control technology.

[0003] In related technologies, vehicle anti-theft control solutions mainly focus on intrusion protection at the vehicle level. For example, by using door locking and vehicle tilt alarms, sound and light alarms are triggered when unauthorized entry or movement of the vehicle is detected. In addition, some solutions use current sensors in high-voltage circuits to monitor abnormal discharge or illegal electricity use when the vehicle is powered on.

[0004] However, the above solutions all have significant shortcomings. Door locking and tilt alarms can only detect physical intrusion at the vehicle level and cannot identify the act of disassembling power components individually or disconnecting the high-voltage connection circuit. The current monitoring solution relies on the vehicle being powered on. When the vehicle is powered off and in hibernation mode, the high-voltage circuit is actively disconnected, and the current sensor cannot work. At this time, it cannot effectively detect the disassembly of power components. Therefore, the existing technology cannot monitor the status of high-voltage power components when the vehicle is powered off, and it cannot perform anti-theft operations in a timely manner when components are stolen, resulting in a high risk of theft of high-voltage power components when the vehicle is not in use. Summary of the Invention

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0020] In a first aspect, embodiments of this application provide a vehicle anti-theft control method.

[0021] In one embodiment, reference is made to Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the vehicle anti-theft control method of this application. Figure 1 As shown, vehicle anti-theft control methods include: Step S10: After the vehicle is powered off and enters sleep mode, a detection level signal is output to the locking device, and a feedback level signal is received from the locking device based on the detection level signal, wherein the locking device is connected to the power unit; In this embodiment, after the vehicle is turned off and powered down, it enters a static sleep state. The control system initiates the anti-theft monitoring process and sends detection level signals to the locking devices connected to each power component. The detection level signals form a path through the circuit where the locking devices are located. The control system simultaneously collects the feedback level signals returned from the circuit and collects the connectivity status of the locking devices to obtain real-time status data of the power component connection structure, providing a basic signal basis for subsequent status judgment.

[0022] Step S20: Based on the consistency between the feedback level signal and the detection level signal, determine whether the connection status of the power component is abnormal; In this embodiment, after the control system acquires the feedback level signal, it compares the feedback level signal with the output detection level signal to verify whether the signal characteristics of the two are consistent. Based on the comparison result of signal consistency, two working conditions are distinguished: when the signal is consistent, it is determined that the locking device is intact and the connection status of the power component is normal; when the signal consistency is not met, it is determined that the locking device is damaged and / or the connection status of the power component is abnormal.

[0023] Step S30: If an abnormality is detected, an anti-theft alarm signal is generated, and a corresponding anti-theft operation is performed based on the anti-theft alarm signal. The anti-theft alarm signal includes the target power component identification information.

[0024] In this embodiment, when the connection status of the power component is determined to be abnormal, the control system generates an anti-theft alarm signal carrying the identification information of the target power component. The abnormal power component can be distinguished by the identification information. The control system uses the anti-theft alarm signal as a trigger command to execute the corresponding anti-theft operation to prevent the power component from being stolen, dismantled and moved, thereby realizing the anti-theft protection of the vehicle's power component.

[0025] In this embodiment, after the vehicle is powered off and enters sleep mode, a detection level signal is output to the locking device, and a feedback level signal returned by the locking device based on the detection level signal is received. The locking device is connected to the power component. Based on the consistency between the feedback level signal and the detection level signal, it is determined whether the connection status of the power component is abnormal. This enables continuous monitoring of the power component in sleep mode, allowing for timely detection of disassembly or disconnection abnormalities. If an abnormality is detected, an anti-theft alarm signal including the target power component's identification information is generated, and corresponding anti-theft operations are performed based on the anti-theft alarm signal. This ensures the rapid and reliable transmission of the alarm signal and improves the overall vehicle anti-theft capability.

[0026] Further, in one embodiment, the detection level signal is a pulse signal with a preset frequency and a preset duty cycle. Determining whether the connection status of the power component is abnormal based on the consistency between the feedback level signal and the detection level signal includes: The feedback level signal is analyzed to obtain the corresponding feedback frequency and feedback duty cycle. If the feedback frequency is consistent with the preset frequency and the feedback duty cycle is consistent with the preset duty cycle, the connection status of the corresponding power component is determined to be normal. If the feedback frequency is inconsistent with the preset frequency, and / or the feedback duty cycle is inconsistent with the preset duty cycle, then the connection status of the corresponding power component is determined to be abnormal.

[0027] In this embodiment, the system collects the feedback level signal transmitted from the locking device (optionally an anti-theft lock) circuit, analyzes the feedback waveform, and accurately extracts the actual frequency and actual duty cycle parameters of the current feedback signal. The analyzed feedback parameters are compared with the system's preset standard pulse parameters. When both the feedback frequency and feedback duty cycle parameters are completely matched with the preset parameters, it indicates that the detection circuit is fully conductive, the locking device has not been damaged, and the connection structure of the power component has not been loosened or disconnected, thus determining that the connection status of the power component is normal. When the feedback frequency is inconsistent, or the feedback duty cycle is inconsistent, or both parameters are mismatched, it indicates that the detection circuit has an open circuit, poor contact, damaged wiring, or the locking device has been pried off. The system determines that the connection status of the power component is abnormal, accurately identifying the risk of component theft.

[0028] Furthermore, in one embodiment, after determining whether the connection status of the power component is abnormal, the method further includes: The process involves outputting a detection level signal to the locking device N times according to a preset detection cycle, and receiving a feedback level signal from the locking device based on the detection level signal. This process is used to determine whether the connection status of the power component is abnormal, resulting in N judgment results. If there are K consecutive judgment results that are abnormal, it is confirmed that the power component is at risk of being stolen, and the anti-theft alarm signal is generated, wherein K is less than or equal to N.

[0029] In this embodiment, an abnormal result obtained during the initial detection does not directly indicate theft or tampering, thus avoiding false alarms caused by accidental factors such as momentary line interference and signal jitter. After the initial determination that the connection status of the power component is abnormal, the system initiates an anti-jitter verification process. Preferably, the complete detection process is repeated 5 times (N=5) according to a preset detection cycle, which is preferably 3 seconds. In each round, a detection level signal is output, a feedback level signal is collected, and a status judgment is completed, resulting in 5 sets of independent judgment results. Subsequently, the system screens the continuous detection results. Only when 3 consecutive results (K=3) are detected as abnormal is it determined that the locking device has been continuously damaged, confirming that the power component is at real risk of theft, and thus generating an anti-theft alarm signal. Through the filtering mechanism of continuous multiple sampling and verification, false anomalies caused by momentary interference are effectively eliminated, improving the reliability of the anti-theft detection results.

[0030] Furthermore, in one embodiment, generating the burglar alarm signal includes: Based on the transmission channel of the feedback level signal corresponding to the abnormal connection state, the target power component associated with the transmission channel is determined, and an anti-theft alarm signal containing the identification information of the target power component is generated.

[0031] In this embodiment, the vehicle is equipped with independent signal detection channels for each power component. Each detection channel uniquely corresponds to a set of matching locking devices and power components. Each channel is independent and does not interfere with others. When the system detects an abnormal signal level, it can accurately locate the abnormal signal transmission channel. Based on the preset binding relationship between the channel and the power component, it quickly matches the target power component with the connection abnormality. Simultaneously, the system integrates and encapsulates the unique identification information of this target power component into the anti-theft alarm signal, so that the final generated anti-theft alarm signal carries specific abnormal component information, achieving precise fault location. Preferably, as follows... Figure 2 As shown, the vehicle control unit (VCU) has four independent detection loops: detection loop 1, detection loop 2, detection loop 3, and detection loop 4. Each of these loops corresponds to one of four high-value power components: the power battery, drive motor, motor controller, and on-board charger. Each loop is connected in series with the corresponding locking device for that power component. The VCU independently outputs detection level signals and collects feedback level signals through each loop, with different detection loops isolated from each other. When an abnormal signal occurs in a detection loop, the VCU can directly identify the channel number where the abnormality occurred. Relying on the pre-established one-to-one binding relationship between the channel and the power component, it can accurately locate the target power component at risk of theft. The identification information of this power component is then written into the anti-theft alarm signal. Simultaneously, the VCU sends the anti-theft alarm signal to the chassis domain, body domain, and on-board remote communication terminal (Tbox) via the controller area network (CAN bus), executing local anti-theft actions and reporting to the cloud, achieving precise alarm at the component level.

[0032] Furthermore, in one embodiment, such as Figure 3 As shown, Figure 3 The diagram illustrates the anti-theft operation process. The anti-theft operation based on the anti-theft alarm signal includes any one of the following: prohibiting the vehicle from being powered on by high voltage and limiting the battery's permissible output power; blocking the drive circuit transistors and limiting the vehicle's drive torque; locking the doors and windows and activating the vehicle's hazard warning lights; locking the electronic parking brake and the vehicle's steering mechanism; and displaying an alarm prompt on the vehicle's screen and increasing the volume of the vehicle's audio alarm.

[0033] In this embodiment, after the vehicle controller detects an abnormal connection status of the anti-theft lock, it sends an anti-theft abnormality signal to the outside via the CAN bus. After receiving the anti-theft alarm signal, each vehicle control unit executes the corresponding anti-theft operation in parallel, which can be any one or more of the following: the battery management system performs an operation to prohibit the vehicle from high voltage power-on and limits the battery's permissible output power; the motor controller blocks the drive circuit transistors, prohibits the power devices from opening, and limits the vehicle's drive torque; the body domain controller locks the doors and windows, and at the same time controls the lights to turn on the hazard warning lights; the chassis domain controller locks the electronic parking brake (EPB) and the vehicle steering mechanism; the cockpit domain controller drives the instrument and entertainment display to pop up alarm pop-ups and increases the vehicle audio volume to realize audible and visual alarms.

[0034] Furthermore, in one embodiment, such as Figure 3 As shown, the step of performing the corresponding anti-theft operation based on the anti-theft alarm signal includes: The anti-theft alarm signal is analyzed to obtain the identification information of the target power component; Determine the current vehicle location information and timestamp information, and encapsulate the vehicle location information, timestamp information, target power component identification information, and anomaly type information into a remote reporting message; The remote reporting message is sent to the vehicle cloud system, so that after receiving the remote reporting message, the vehicle cloud system pushes a theft risk warning generated based on the remote reporting message to the user terminal APP bound to the vehicle.

[0035] In this embodiment, after the vehicle controller generates an anti-theft alarm signal, the Tbox receives the signal via the CAN bus. First, it parses the alarm signal to extract the target power component identification information and anomaly type information, identifying which power component has a connection abnormality. Then, the onboard remote communication terminal reads the current vehicle location information output by the positioning module and simultaneously reads the system clock to obtain the timestamp information, recording the location and exact time of the abnormal event. The onboard remote communication terminal integrates and encapsulates the vehicle location information, timestamp information, target power component identification information, and anomaly type information. This solution generates standardized remote reporting messages and transmits them to the backend vehicle cloud system via mobile communication networks. Upon receiving the messages, the system parses the information within, generates a theft risk alert message containing details of the abnormal component, the location of the incident, and the time of the incident, and proactively pushes this message to user terminals such as mobile apps pre-linked to the vehicle. This allows vehicle owners to remotely and promptly monitor the risk of vehicle theft. This solution achieves a linked reporting system from local vehicle anomalies to the cloud, adding remote early warning capabilities to the on-site anti-theft protection actions, enabling vehicle owners to be informed of potential dangers immediately and take timely action. Furthermore, in one embodiment, the vehicle anti-theft control method further includes: After the vehicle is powered off and enters sleep mode, it enters a timed wake-up state according to a preset time cycle, and outputs a detection level signal to the locking device each time it enters the wake-up state.

[0036] In this embodiment, after the vehicle completes the power-off operation, the vehicle controller enters a low-power sleep mode to reduce the vehicle's power load and prevent power depletion due to prolonged vehicle idling. The internal timing module of the vehicle controller runs continuously, and when the preset time period (preferably 3 seconds) is reached, the vehicle controller automatically wakes up from the sleep state. After waking up, the vehicle controller immediately outputs detection level signals to the locking devices corresponding to each power component, collects the feedback level signals of each detection circuit, and completes one round of anti-theft lock connection status detection. When all detection work in this round is completed, if no connection abnormality is detected, the vehicle controller re-enters the sleep state, waiting for the next cycle wake-up. If an anti-theft lock connection abnormality is detected, subsequent abnormality judgment, anti-theft alarm signal generation, and various anti-theft protection operations are immediately executed. This periodic wake-up detection scheme does not require the vehicle controller to remain continuously in working state, taking into account both the anti-theft monitoring needs of stationary vehicles and the static power consumption control of the vehicle, and is suitable for scenarios where vehicles are parked for a long time.

[0037] Secondly, embodiments of this application also provide a vehicle anti-theft control system.

Figure 4 As shown, the vehicle anti-theft control system includes: The detection module is used to output a detection level signal to the locking device after the vehicle is powered off and put into sleep mode, and to receive a feedback level signal returned by the locking device based on the detection level signal, wherein the locking device is connected to the power unit; The judgment module is used to determine whether the connection status of the power component is abnormal based on the consistency between the feedback level signal and the detection level signal. The generation module is used to generate an anti-theft alarm signal if an anomaly occurs, and to perform corresponding anti-theft operations based on the anti-theft alarm signal, wherein the anti-theft alarm signal includes the target power component identification information.

[0039] Furthermore, in one embodiment, the generation module is used to: The anti-theft alarm signal is analyzed to obtain the identification information of the target power component; Determine the current vehicle location information and timestamp information, and encapsulate the vehicle location information, timestamp information, target power component identification information, and anomaly type information into a remote reporting message; The remote reporting message is sent to the vehicle cloud system, so that after receiving the remote reporting message, the vehicle cloud system pushes a theft risk warning generated based on the remote reporting message to the user terminal bound to the vehicle.

[0040] Furthermore, in one embodiment, the determination module is used to: The feedback level signal is analyzed to obtain the corresponding feedback frequency and feedback duty cycle. If the feedback frequency is consistent with the preset frequency and the feedback duty cycle is consistent with the preset duty cycle, the connection status of the corresponding power component is determined to be normal. If the feedback frequency is inconsistent with the preset frequency, and / or the feedback duty cycle is inconsistent with the preset duty cycle, then the connection status of the corresponding power component is determined to be abnormal.

[0041] Furthermore, in one embodiment, the vehicle anti-theft control system further includes an execution module for: The process involves outputting a detection level signal to the locking device N times according to a preset detection cycle, and receiving a feedback level signal from the locking device based on the detection level signal. This process is used to determine whether the connection status of the power component is abnormal, resulting in N judgment results. If there are K consecutive judgment results that are abnormal, it is confirmed that the power component is at risk of being stolen, and the anti-theft alarm signal is generated, wherein K is less than or equal to N.

[0042] Furthermore, in one embodiment, the generation module is used to: Based on the transmission channel of the feedback level signal corresponding to the abnormal connection state, the target power component associated with the transmission channel is determined, and an anti-theft alarm signal containing the identification information of the target power component is generated.

[0043] Furthermore, in one embodiment, the anti-theft operation includes any one of the following: prohibiting the vehicle from being powered on at high voltage and limiting the battery's permissible output power; blocking the drive circuit transistors and limiting the vehicle's drive torque; locking the doors and windows and activating the vehicle's hazard warning lights; locking the electronic parking brake and the vehicle's steering mechanism; and displaying an alarm prompt on the vehicle's display screen and increasing the volume of the vehicle's audio alarm.

[0044] Furthermore, in one embodiment, the vehicle anti-theft control system further includes a wake-up module, used for: After the vehicle is powered off and enters sleep mode, it enters a timed wake-up state according to a preset time cycle, and outputs a detection level signal to the locking device each time it enters the wake-up state.
