Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of automobile security technology, in particular to a vehicle body anti-theft method and system based on in-vehicle living body detection. BACKGROUND

[0002] The current vehicle body anti-theft system is a system for detecting whether the vehicle is illegally intruded, which usually has six states of disarming, arming, alarm, pre-rearming, separate disarming, and arming failure. Living body detection is a technology for continuous monitoring during the above six states. When the vehicle is armed and unlocked, the vehicle will switch to pre-rearming. If a living body is detected during pre-rearming, the automatic locking function needs to be shielded to protect the life safety of the in-vehicle living body.

[0003] The vehicle body anti-theft alarm system has the following sub-states: A. Arming Mode: In this state, the door and power state are monitored, and any door opening or power switch to ON will trigger an alarm; B. Pre_rearming Mode: The state before disarming in the arming state, if any door is not opened and the power gear is not switched within 30 seconds, the automatic relocking and automatic arming again will be triggered; C. Trunk Opening Mode: A special arming state, opening the trunk / hatch will not trigger an alarm; D. Alarm Mode: In the arming state, illegal intrusion is detected, i.e. illegal door opening, which will trigger an anti-theft alarm; E. Disarm Mode: This state does not monitor intrusion; F. Arming Fault Mode: This state is a temporary state for triggering an arming failure prompt.

[0004] The prompts triggered by different states are different, which can be divided into the following cases: arming prompt, disarming / pre-rearming prompt, arming failure prompt, pre-rearming to arming prompt, two-cover separate disarming prompt, and alarm prompt. The vehicle body anti-theft system switches according to different states and sends corresponding anti-theft states and control instructions to the associated system (turning light, horn, rearview mirror, door lock, etc.). The associated system will control its enable output and period according to the specification requirements after receiving the instructions. For example, after receiving the arming prompt control instruction, the left and right turning lights will be lit for 480 ms and then extinguished, while the corresponding water flow enable output is controlled; after receiving the arming prompt control instruction, the rearview mirror will control the rearview mirror motor to perform folding action.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0045] like Figure 1 As shown, a vehicle anti-theft method based on in-vehicle liveness detection includes:

[0046] S101, when the vehicle is in the disarming state, the power state is Off or Com gear or OTA is valid, and the four doors and two covers are closed, the main driver seat is determined to be unoccupied, and the vehicle enters the arming state after receiving the locking instruction;

[0047] S102, during the arming, the vehicle enters the pre-arming state after receiving the unlocking instruction;

[0048] S103, after entering the pre-arming state, start timing, and when detecting the presence of living beings in the vehicle during the timing, shield to the arming state, and the shield is automatically relocked.

[0049] In a specific implementation, when the FMCW radar senses the presence of living beings, the living being signal is sent to the left domain controller through the RTE (Run-Time Environment), and the vehicle body anti-theft system receives the living being interface signal abstracted by the left domain controller, judges whether the vehicle exists living beings, and combines the current vehicle anti-theft state to perform corresponding control. When the living being detection interface signal (SI_u8_InCarRadio) is 1 and the vehicle power mode is Off or Com gear, the functions of automatically relocking after pre-arming for 30 seconds and rearming are shielded (SL_u8_SecArmingFlag = 1), and when any door of the four doors is opened (half open or fully open), the function of automatically relocking after pre-arming for 30 seconds is allowed (SL_u8_SecArmingFlag = 0).

[0050] In an embodiment, the locking instruction includes:

[0051] BNCM remote locking, BNCM leaving locking, BNCM Bluetooth locking, PE locking, NFC card unlocking, TBox remote locking.

[0052] In an embodiment, the unlocking instruction includes:

[0053] PE unlocking, NFC card unlocking, BNCM approaching unlocking, BNCM remote unlocking, TBox remote unlocking.

[0054] In an embodiment, after entering the pre-arming state, start timing, and then further include:

[0055] When detecting any door opening, the main driver being present, or the power becoming ON or Com gear during the timing, the timing is cleared, and the disarming state is entered.

[0056] In an embodiment, after entering the pre-arming state, start timing, and then further include:

[0057] After the timing period is full, and no living beings are detected in the vehicle during the timing period, the pre-arming state is converted to the arming state.

[0058] In an embodiment, when a living body is detected in the vehicle during the timing, the shield is turned to the armed state, and the shield is automatically relocked, and then further comprising:

[0059] When any door of the four doors is detected to be opened, the shield is allowed to be turned into the pre-armed state and automatically relocked after a certain time.

[0060] In an embodiment, detecting a living body in the vehicle comprises:

[0061] The transmitting end transmits a linear frequency modulation pulse signal, and the receiving end receives a frequency modulation pulse signal reflected by the object; the linear frequency modulation pulse signal and the frequency modulation pulse signal reflected by the object are mixed to obtain an intermediate frequency signal;

[0062] The frequency spectrum of the intermediate frequency signal is obtained by Fourier transform; when it is detected that the correlation coefficient of the frequency spectrum data of adjacent two Fourier transforms within T time is greater than a threshold value, it is indicated that there is no living body; when it is detected that the correlation coefficient of the frequency spectrum of adjacent two Fourier transforms within T time is less than a threshold value, it is indicated that there is a living body in the vehicle.

[0063] In specific implementation, during the entire anti-theft state, the FMCW radar periodically transmits a frequency modulation continuous wave signal for living body detection, and the frequency modulation continuous wave signal has a starting frequency (fc), a bandwidth (B), a transmission time (T), and a transmission slope (S) of the frequency modulation signal.

[0064] For a single static object, Tx transmits a frequency modulation continuous wave signal, when the frequency modulation continuous wave signal contacts the object, reflection occurs, and the reflected signal is received by Rx. The Rx received signal can be regarded as a delay of Tx, and the Rx received signal and the Tx transmitted signal pass through a mixer to generate an intermediate frequency signal (IF) with a constant frequency. The frequency of the intermediate frequency signal is closely related to the propagation distance (d) of the Tx transmitted signal in space. For example, for a static object with a distance (d1), the propagation time t of the electromagnetic wave signal in the air is t = 2xd1 / c, c represents the speed of light (the propagation speed of the electromagnetic wave in the air), and the frequency of the intermediate frequency signal is F1 = Sx(2xd1 / c). When a living body in the vehicle moves, the relative distance between the object and the radar also changes, assuming d1 ′ , the propagation time t2 of the electromagnetic wave signal in the air is t2 = 2xd1 ′ / c, and the frequency of the intermediate frequency signal is F2 = Sx(2xd1 ′ / c); Frequency shifts can be observed in the spectrum using Fourier Transform (FFT). Conversely, when there are no living beings inside the vehicle, all objects inside the vehicle (such as seats, center console, etc.) are stationary relative to the radar, and therefore no frequency shift occurs. In other words, when the correlation coefficient of the spectrum data of two Fourier transforms is equal to or approximately 1 over a certain period of time, it indicates that there are no living beings; when the correlation coefficient of the spectrum data of two Fourier transforms is not equal to 1 over a certain period of time, it indicates that there are living beings inside the vehicle.

[0065] like Figure 2 As shown, a vehicle anti-theft system based on in-vehicle liveness detection includes: a defense unit 201, a pre-re-defense unit 202, and a liveness detection unit 203;

[0066] Arming unit 201 is used when the whole vehicle is in the disarmed state, the power supply is in the Off or Com position or the OTA is effective, and the four doors and two hoods are closed, the driver's seat is determined to be unoccupied, and after receiving the lock command, the whole vehicle enters the armed state.

[0067] The pre-arming unit 202 is used to ensure that the vehicle enters a pre-arming state after receiving an unlocking command during the arming period.

[0068] The liveness detection unit 203 is used to start timing after entering the pre-rearming state. When a live body is detected in the vehicle during the timing period, the shield switches to the arming state and the shield automatically relocks.

[0069] like Figure 3 As shown, this disclosure provides an electronic device, including a processor 301, a communication interface 302, a memory 303, and a communication bus 304, wherein the processor 301, the communication interface 302, and the memory 303 communicate with each other through the communication bus 304;

[0070] Memory 303 stores computer programs;

[0071] The processor 301 implements the above method when executing a computer program stored in the memory 303.

[0072] This disclosure provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described method.

[0073] The computer-readable storage medium may be included in the device / apparatus described in the above embodiments; or it may exist independently and not assembled into the device / apparatus. The computer-readable storage medium carries one or more programs that, when executed, implement the method according to the embodiments of this disclosure.

[0074] According to embodiments of the present disclosure, the computer readable storage medium can be a non-volatile computer readable storage medium, for example, can include but is not limited to: portable computer disk, hard disk, random access memory (RAM), read only memory (ROM), erasable programmable read only memory (EPROM or flash memory), portable compact disk read only memory (CD-ROM), optical storage device, magnetic storage device, or any suitable combination of the above. In the present disclosure, the computer readable storage medium can be any tangible medium containing or storing a program that can be used by or in conjunction with an instruction execution system, device or apparatus.

[0075] To enable those skilled in the art to better understand the present disclosure, the principles of the present disclosure are described below in conjunction with the accompanying drawings:

[0076] Millimeter wave is a radar technology for wireless sensing using short-wavelength electromagnetic waves. After the radar system transmits millimeter wave signals, the signals will be reflected when contacting an object. By capturing the reflected signals, the distance, speed and angle of the object can be calculated. According to this feature, millimeter wave can be used for in-vehicle living body detection. Compared with placing a camera in the vehicle for living body detection, millimeter wave pays more attention to protecting the privacy of passengers.

[0077] Frequency-modulated continuous wave (FMCW) is a millimeter wave whose frequency varies linearly with time. The radar is composed of a synthesizer, a transmitting antenna (Tx), a receiving antenna (Rx), a mixer and other components, as shown in FIG. 1. The working principle is as follows: the synthesizer synthesizes a linear frequency modulation pulse signal, which is transmitted by the Tx. When the signal contacts an object, it will be reflected. The reflected signal is captured by the Rx and, together with the Tx transmitted signal, passes through the mixer to generate an intermediate frequency signal with a constant frequency. Figure 4

[0078] The present disclosure proposes a function of shielding automatic relocking when a living body is detected during pre-resetting defense. The specific scenarios are as follows:

[0079] (1): When the vehicle is in defense, the power state is Off or in Com gear or OTA is valid, and the four doors and two covers are closed, the main driver judges that there is no one, and after the locking operation (BNCM remote locking, BNCM away from locking, BNCM Bluetooth locking, PE locking, NFC card unlocking, TBox remote locking), the vehicle will enter the defense and trigger the defense prompt.

[0080] (2): During the defense, after receiving the unlocking instruction (PE unlocking, NFC card unlocking, BNCM approaching unlocking, BNCM remote unlocking, TBox remote unlocking), the vehicle will enter the pre-resetting defense and trigger the defense prompt.

[0081] ​(3): After entering the pre-rearming mode, start the timer TPR; if any door is opened, or the main driver is present, or the power is turned on or the Com file is detected during TPR < 30s, the timer is cleared, and the disarming mode is entered; otherwise, after 30s of timing, the arming mode is automatically jumped from the pre-rearming mode (Pre_Rearming Mode), at this time, if it is detected that there is a living body in the car, the automatic relocking is shielded, and if there is no living body detected in the car, the automatic relocking is triggered.

[0082] During the entire anti-theft state described above, the FMCW radar periodically sends a frequency-modulated continuous wave signal for living body detection, which has a starting frequency (fc), a bandwidth (B), a transmission time (T), and a transmission slope (S) of the frequency-modulated signal, as shown in Figure 5 .

[0083] For a single static object, the Tx transmits a frequency-modulated continuous wave signal, when the frequency-modulated continuous wave signal contacts the object, a reflection occurs, and the reflection signal is received by the Rx, which can be regarded as a delay of the Tx, the Rx received signal and the Tx transmitted signal pass through the mixer to generate a constant frequency intermediate frequency signal (IF), the frequency of the intermediate frequency signal is closely related to the propagation distance (d) of the Tx transmitted signal in space, as shown in Figure 6 . For example, for a static object with a distance (d1), the propagation time of the electromagnetic wave signal in the air t = 2xd1 / c, c represents the speed of light (the propagation speed of the electromagnetic wave in the air), then the frequency of the intermediate frequency signal When there is a living body in the car that moves, the relative distance between the object and the radar will also change, assuming d1 ′ , the propagation time of the electromagnetic wave signal in the air t2 = 2xd1 ′ / c, then the frequency of the intermediate frequency signal F2 = Sx(2xd1 ′ / c); as shown in Figure 7 , the frequency shift can be observed in the frequency spectrum by Fourier transform (FFT). Conversely, when there is no living body in the car, all objects (such as seats, center consoles, etc.) in the car are in a static state relative to the radar, and there will be no frequency shift. That is, when the correlation coefficient of the frequency spectrum data of two Fourier transforms within a period of time is equal to or approximately 1, it means that there is no living body; when the correlation coefficient of the frequency spectrum data of two Fourier transforms within a period of time is not equal to 1, it means that there is a living body in the car.

[0084] When the FMCW radar senses the presence of a living body, the living body signal is sent to the left domain controller through the RTE (Run-Time Environment), the vehicle anti-theft system receives the living body interface signal abstracted by the left domain controller, judges whether the vehicle exists a living body, and combines the current vehicle anti-theft state to perform corresponding control. When the living body detection interface signal (SI_u8_InCarRadio) is 1 and the vehicle power mode is in Off or Com, the function of automatically relocking and resetting the alarm after 30 seconds of pre-resetting the alarm (SL_u8_SecArmingFlag=1) is shielded. When any door of the four doors is opened (half open or fully open), the function of automatically relocking (SL_u8_SecArmingFlag=0) after 30 seconds of pre-resetting the alarm is allowed.

[0085] Although the present disclosure is described in detail with reference to the foregoing embodiments, it should be understood that modifications can be made to the technical solutions described in the foregoing embodiments, or equivalent replacements can be made to part of the technical features, and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
