Unlocking and locking system and vehicle

Abstract

The invention discloses an unlocking and locking system and a vehicle. The unlocking and locking system comprises an infrared sensor, a near field communication module and a controller. The infrared sensor is used for detecting whether someone exists. And the near field communication module is used for communicating with communication equipment. When the electronic lock of the vehicle is in a locked state and the infrared sensor detects that someone exists, the controller is awakened to awaken the near field communication module, and the controller sends an unlocking signal to a processor of the vehicle to unlock the electronic lock of the vehicle under the condition that the near field communication module communicates with the communication equipment. Therefore, only the infrared sensor is in a working state when no person approaches the vehicle, so that the energy consumption of the unlocking and locking system is greatly reduced. Meanwhile, when the user is in a long distance, the near field communication module can be awakened in time, and when the card swiping sensing distance is long when the user unlocks, the communication equipment can also be recognized by the near field communication module. Therefore, the unlocking and locking system can give consideration to both energy consumption and card swiping sensing distance.

[0009] In some embodiments, the unlocking system further includes an insulating member located between the antenna board and the main board.

[0010] In certain embodiments, the insulating member comprises ferrite.

[0011] In some embodiments, the near field communication module does not emit a communication signal field when in a dormant state.

[0012] In some embodiments, after the infrared sensor detects a person for the first time, if the infrared sensor detects a person again after a preset delay, the controller wakes up the near field communication module.

[0016] In some embodiments, when the vehicle is in a parked state and the main driver's door is opened, the controller wakes up the infrared sensor; when the detection result of the infrared sensor indicates that a person in the main driver's door has gotten off the vehicle, the controller wakes up the near-field communication module.

[0017] In some embodiments, when the NFC module is in communication with the communication device, the controller sends a lock signal to a processor of the vehicle to close an electronic lock of the vehicle.

[0018] In some embodiments, when the near-field communication module communicates with the communication device, after the infrared sensor detects that no person is detected for the first time, if the infrared sensor detects that no person is detected within a first preset delay period, the controller and the near-field communication module enter a sleep mode.

[0019] In certain embodiments, after the near-field communication module is awakened, if the near-field communication module does not communicate with the communication device within a second preset delay period and the electronic lock is in a locked state, then after the infrared sensor detects that no person is detected for the first time, if the infrared sensor detects that no person is detected within a third preset delay period, the controller and the near-field communication module enter a sleep mode.

[0020] In certain embodiments, the controller determines that the electronic lock is switched from the unlocked state to the locked state based on a lock signal from a processor of the vehicle.

[0021] In some embodiments, after the near-field communication module is awakened, if the near-field communication module does not communicate with the communication device within a second preset delay period, the electronic lock is in an unlocked state, and the controller sends a check prompt signal to the processor, so that the processor notifies a preset user to check and confirm whether the vehicle is locked.

[0022] In certain embodiments, within a second preset delay period after the near-field communication module is awakened, if the near-field communication module does not communicate with the communication device and the electronic lock is in an unlocked state, then if the detection result of the infrared sensor is that no person is detected, the controller sends a check prompt signal to the processor, so that the processor notifies a preset user to check and confirm whether the vehicle is locked.

[0023] In some embodiments, within a fourth preset delay period after the check prompt signal is issued, if the detection results of the infrared sensor are all no detection of a person, the near field communication module and the controller enter a dormant state.

[0024] In some embodiments, within a fourth preset delay period after the inspection prompt signal is issued, if the infrared sensor detects a person, the near-field communication module and the controller maintain the current state until the electronic lock is switched to a locked state.

[0029] In some embodiments, the detection range of the infrared sensor is determined based on a walking range of the vehicle owner when approaching the vehicle.

[0030] In some embodiments, the vehicle includes a door, and the electronic lock is mounted on the door.

[0031] The unlocking system and vehicle of the embodiment of the present application are provided with an infrared sensor, a near-field communication module and a controller. When the electronic lock of the vehicle is in a locked state and a person is detected, the infrared sensor can wake up the controller, and the controller wakes up the near-field communication module. After being awakened, the near-field communication module enters the working mode and can send out a strong signal pulse to communicate with the user's communication device. When the near-field communication module communicates with the user's communication device, the controller can send an unlocking signal to the vehicle's processor. After the vehicle's processor obtains the unlocking signal, it will unlock the vehicle's electronic lock, thereby completing the unlocking of the vehicle's electronic lock. In this way, when no one approaches the vehicle, the controller and the near-field communication module will be in a dormant state, and only the infrared sensor will be in a working state, thereby greatly reducing the energy consumption of the unlocking system. At the same time, the infrared sensor of this application can detect the approach of a human body at a relatively long distance. Therefore, when the user approaches the unlocking system, the near-field communication module has entered the working mode and can emit a strong communication signal field to communicate with the user's communication device. It can be understood that at this time, even if the card swipe sensing distance is far, the user's communication device can still be recognized by the near-field communication module, thereby improving the user experience. In this way, this application can balance energy consumption and card swipe sensing distance.

[0049] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and should not be understood as limiting the embodiments of the present application.

[0050] Currently, some vehicles offer near-field communication (NFC) card unlocking for exterior mirrors. The card sensing distance affects the user experience, and power consumption is crucial for NFC modules. Therefore, balancing card sensing distance and power consumption has become a pressing issue.

[0051] The NFC solutions currently installed in cars have high standby power consumption and poor card sensing distance. The main reason is that the NFC antenna area is limited by the complex structure inside the rearview mirror and cannot be made too large. In addition, the NFC standby mode is the Low Power Card Detection (LPCD) state. The trigger waveform has a short duration and relatively weak transmission energy. The mobile phone needs to be as close as possible to the rearview mirror to trigger the vehicle-side NFC to enter Polling mode and complete communication with the mobile phone NFC. Polling is a polling working mode for information exchange between NFC devices. For example Figure 1 This is the waveform of LPCD sleep mode. Figure 2 This is the waveform diagram of the Polling communication mode. Figure 1 and Figure 2 The vertical lines and squares are pulses transmitted by NFC.

[0052] At present, some in-vehicle NFC unlocking solutions have a sleep current of about 1.2mA@5V in LPCD mode with 10 cycles within 1s, and a sleep current of about 12mA@5V in LPCD mode with 3 polling cycles plus 6 cycles within 1s. In some solutions, in order to increase the card swiping sensing distance in sleep state, the sleep state is a combination of polling mode and LPCD mode, for example Figure 3 That is the communication mode waveform in the dormant state, the vertical lines are the waveforms transmitted in the LPCD mode, and the vertical squares are the waveforms transmitted in the polling mode.

[0053] To increase the card swipe sensing distance, you need to increase the number of polling wake-ups and improve the NFC triggering energy to trigger the phone's NFC at a longer distance. To reduce power consumption, you need to increase the number of LPCDs and reduce the polling energy. Therefore, with the current solution, it is difficult to balance power consumption and card swipe sensing distance.

[0054] To solve the above problems, please refer to Figure 4 The present application provides an unlocking system 100, which includes an infrared sensor 10, a near-field communication module 20, and a controller 30. The infrared sensor 10 is used to detect whether a person is present. The near-field communication module 20 is used to communicate with a communication device. When the electronic lock 200 of the vehicle 1000 is locked and the infrared sensor 10 detects the presence of a person, the controller 30 is awakened to wake up the near-field communication module 20. When the near-field communication module 20 communicates with the communication device, the controller 30 sends an unlocking signal to the processor 300 of the vehicle 1000 to unlock the electronic lock 200 of the vehicle 1000.

[0055] Specifically, Near Field Communication (NFC) is an emerging technology that enables devices (e.g., mobile phones) using NFC to exchange data when in close proximity. The unlocking system 100 can be installed on a vehicle 1000 to facilitate opening and closing of the electronic lock 200 of the vehicle 1000 via NFC. The electronic lock 200 of the vehicle 1000 can be installed at any location, and in particular, the electronic lock 200 can be a door lock of the vehicle 1000. The processor 300 of the vehicle 1000 can control the opening and closing of the electronic lock 200.

[0056] The communication device is a device capable of installing an NFC module, such as a mobile phone, tablet, special phone case, or NFC card reader. A user can communicate with the near-field communication module 20 of the unlocking system 100 through the communication device to control the electronic lock 200 of the vehicle 1000. When the electronic lock 200 of the vehicle 1000 is locked, if the communication device communicates with the near-field communication module 20 of the unlocking system 100, the controller 30 (Microcontroller Unit, MCU) can receive the communication and send an unlock signal to the processor 300 of the vehicle 1000 to unlock the electronic lock 200 of the vehicle 1000. When the electronic lock 200 of the vehicle 1000 is unlocked, if the communication device communicates with the near-field communication module 20 of the unlocking system 100, the controller 30 can receive the communication and send a lock signal to the processor 300 of the vehicle 1000 to close the electronic lock 200 of the vehicle 1000.

[0057] The infrared sensor 10 is a sensor that uses infrared rays to process data and has advantages such as high sensitivity. The infrared sensor 10 can control the operation of the drive device and includes a thermal infrared sensor 10 and a pyroelectric infrared sensor 10. In nature, all objects with a temperature above absolute zero (-273°C) will radiate infrared rays, and the radiation wavelength is between 0.77 and 1000 μm. The higher the temperature of the object, the stronger the infrared radiation energy and the easier it is to detect. Therefore, infrared detection is one of the important means of detecting objects. The infrared sensor 10 contains one or more infrared detectors that can receive and detect infrared radiation from the object being detected. When a human body approaches the infrared sensor 10, the infrared radiation it emits will be received by the sensor. The received infrared radiation signal will be converted into an electrical signal and amplified, filtered, and processed by the signal processing system. Therefore, the infrared sensor 10 can be used to detect whether there is a person near the unlocking system 100.

[0058] The infrared sensor 10 works by detecting infrared radiation, and this process consumes relatively little power. Therefore, the infrared sensor 10 has relatively low energy consumption, which gives it a significant advantage in many applications that require long-term continuous operation or battery power. For example, the sleep current of an existing NFC module in LPCD mode with 10 cycles within 1 second is approximately 1.2mA@5V, and the sleep current of LPCD mode with 3 polling cycles plus 6 cycles within 1 second is approximately 12mA@5V. The static power consumption of a pyroelectric infrared (PIR) sensor is less than 12μA, which shows that the power consumption of a pyroelectric infrared sensor is very small. At the same time, the detection range of the infrared sensor 10 is generally wide, usually between a few meters and tens of meters. Currently, general products in the industry can achieve a detection distance of 12m with a static power consumption of less than 12μA. By adjusting the voltage divider resistor of the peripheral control circuit, the pyroelectric infrared sensor supports adjustable delay trigger time, adjustable voltage threshold and other settings. The detection range of the near field communication module 20 is generally within 10 centimeters. Obviously, the detection range of the infrared sensor 10 is larger than that of the near field communication module 20 .

[0059] The controller 30 processes data from the infrared sensor 10 and the near-field communication module 20 and also communicates with the processor 300 of the vehicle 1000 to implement the various functions of the unlocking system 100. The near-field communication module 20 can be considered primarily used to acquire and transmit signals and communicate with communication devices. Subsequent data processing and communication with the processor 300 of the vehicle 1000 are performed by the controller 30.

[0060] The unlocking system 100 may also be provided with a battery to supply power to electrical components within the unlocking system 100 , such as the infrared sensor 10 , the near field communication module 20 and the controller 30 , to ensure the normal operation of the unlocking system 100 .

[0061] When no one approaches the vehicle 1000, the controller 30 and the near-field communication module 20 will be in a dormant state, and only the infrared sensor 10 will be in a working state, so as to greatly reduce the energy consumption of the unlocking system 100. In some embodiments, the controller 30 will perform low-energy operation when it is in a dormant state, rather than directly not running, for example, obtaining information every few seconds to facilitate timely data processing. In some embodiments, the controller 30 will directly not run when it is in a dormant state, so as to minimize the energy consumption of the controller 30. In some embodiments, the near-field communication module 20 does not emit a communication signal field, that is, does not emit an NFC field, when it is in a dormant state, and the near-field communication module 20 will directly not run, so as to minimize the energy consumption of the near-field communication module 20. In this way, compared with the existing technology that still emits a communication signal field from time to time when it is in a dormant state, the energy consumption of the near-field communication module 20 of the present application can be greatly reduced. Of course, in some embodiments, the near-field communication module 20 can emit a low-frequency communication signal field when it is in a sleep state, that is, the near-field communication module 20 operates with low power consumption. At this time, the near-field communication module 20 is in the LPCD mode throughout the sleep state, or is in the polling mode for part of the time and in the LPCD mode for part of the time in the sleep state.

[0062] When no one approaches the unlocking system 100, the infrared sensor 10 cannot detect any temperature changes in the detection area and no high-level output is triggered. The near-field communication module 20 and the controller 30 are also in sleep mode, and there is no NFC field emission. The power consumption of the entire system is at its lowest state. If the infrared sensor 10 is a pyroelectric infrared sensor, then at this time the entire system only consumes about 12μA of PIR working current.

[0063] The infrared sensor 10 continuously detects whether there are people nearby. When someone moves near the unlocking system 100 (for example, moves laterally) and enters the detection range of the infrared sensor 10 (a distance of 3-5 meters in front of the vehicle 1000), the infrared sensor 10 can detect the temperature change within the detection range, thereby determining the presence of a person.

[0064] When it is determined that there is a person near the unlocking system 100, it can be considered that the pedestrian may be the user of the unlocking system 100 and may have the need to unlock. At this time, the infrared sensor 10 can wake up the controller 30, for example, by outputting a high level to the controller 30 to wake up the controller 30. Then, the controller 30 can wake up the near-field communication module 20. The awakened near-field communication module 20 enters the working mode and performs the Polling opening action, emitting an NFC field to facilitate communication with the user's communication device, where the NFC field is a strong signal pulse. When the near-field communication module 20 communicates with the user's communication device, it is considered that the user has entered an unlocking command. At this time, an unlocking signal can be sent to the processor 300 of the vehicle 1000. After the processor 300 of the vehicle 1000 obtains the unlocking signal, it will unlock the electronic lock 200 of the vehicle 1000. In this way, the electronic lock 200 of the vehicle 1000 can be unlocked.

[0065] In this way, when no one approaches the vehicle 1000, the controller 30 and the near-field communication module 20 will be in a dormant state, and only the infrared sensor 10 will be in a working state, so as to greatly reduce the energy consumption of the unlocking system 100. The controller 30 and the near-field communication module 20 in the dormant state either consume very little energy or consume no energy at all. At the same time, in the prior art, the near-field communication module 20 will still emit a communication signal field when it is in a dormant state, and the pulses it releases are relatively weak, requiring the user's card swiping sensing distance (i.e., the distance between the communication device and the unlocking system 100) to be close in order to be recognized and enter the working state, resulting in a poor user experience. The infrared sensor 10 of the present application can recognize the approach of the user at a longer distance. The commonly used infrared sensor 10 in the industry can achieve a detection distance of 12m, while the card swiping sensing distance is usually a few centimeters. Therefore, when the user approaches the unlocking system 100, the near-field communication module 20 enters the operating mode and can emit a strong communication signal field to communicate with the user's communication device. It can be understood that at this time, even if the card swipe sensing distance is far, the user's communication device can still be recognized by the near-field communication module 20, thereby improving the user experience. In this way, the present application can balance energy consumption and card swipe sensing distance.

[0066] The unlocking system 100 according to an embodiment of the present application comprises an infrared sensor 10, a near-field communication module 20, and a controller 30. When the electronic lock 200 of the vehicle 1000 is locked and detects a person, the infrared sensor 10 can wake up the controller 30, which then wakes up the near-field communication module 20. After waking up, the near-field communication module 20 enters an operating mode, emitting strong signal pulses to communicate with the user's communication device. When the near-field communication module 20 is communicating with the user's communication device, the controller 30 can send an unlock signal to the processor 300 of the vehicle 1000. Upon receiving the unlock signal, the processor 300 of the vehicle 1000 unlocks the electronic lock 200 of the vehicle 1000, thereby completing the unlocking of the electronic lock 200 of the vehicle 1000. This way, when no one is near the vehicle 1000, the controller 30 and the near-field communication module 20 are both in a dormant state, leaving only the infrared sensor 10 in an active state, significantly reducing the energy consumption of the unlocking system 100. At the same time, the infrared sensor 10 of the present application can detect the approach of a human body at a relatively long distance. Therefore, when the user approaches the unlocking system 100, the near-field communication module 20 has entered the working mode and can emit a strong communication signal field to communicate with the user's communication device. It can be understood that at this time, even if the card swipe sensing distance is far, the user's communication device can still be recognized by the near-field communication module 20, thereby improving the user experience. In this way, the present application can balance energy consumption and card swipe sensing distance.

[0067] See also Figure 4 In some embodiments, the infrared sensor 10 includes a pyroelectric infrared sensor.

[0068] Specifically, the pyroelectric effect refers to the phenomenon that when the ambient temperature of a pyroelectric material changes, the original charge polarization direction of the material changes, thereby releasing charge on the surface of the material and presenting positive and negative electrodes, generating surface voltage and current. As a passive infrared signal receiving element, the pyroelectric infrared sensor has the characteristics of low cost, low power consumption, high sensitivity, and easy installation and deployment. It can adapt to complex and changing external environments and can effectively detect changes in human movement. Therefore, it is widely used in smart lighting, intrusion detection, security monitoring and other fields. The pyroelectric infrared sensor is an infrared radiation detection sensor made using a crystal material with a pyroelectric effect as a sensitive element. It can effectively detect moving human bodies in the area.

[0069] A pyroelectric infrared sensor consists of an infrared filter, a pyroelectric sensing element, a preamplifier, and other circuitry. These components are encapsulated within a metal shielding housing to prevent external interference with the sensor's output signal. The infrared filter used in the pyroelectric infrared sensor is mounted on the upper surface of the metal housing and provides a bandpass filter. Thermal infrared radiation outside the bandpass range that reaches the pyroelectric infrared sensor's filter surface is blocked, effectively allowing infrared radiation signals from the human body to pass through at specific wavelengths. The pyroelectric sensing element is the direct measuring element of the pyroelectric infrared sensor. It is fabricated by adding metal electrodes to the ends of a pyroelectric crystal and then polarizing them. When the pyroelectric detector element is exposed to infrared radiation of varying intensity, the temperature changes on the electrode surfaces cause changes in the charge density across the electrodes, generating a pyroelectric current in the circuit.

[0070] like Figure 5 As shown in the figure, a pyroelectric infrared sensor converts infrared thermal radiation into a detectable electrical signal. When human movement is detected, a high-level signal is generated, triggering a control system response. Since the human body itself is a heat source, emitting an 8-14μm thermal infrared signal, a pyroelectric infrared sensor detection circuit can effectively sense moving heat sources within a specified area. By analyzing the sensed infrared signal, the human's motion state (position, direction, speed, posture, etc.) can be determined.

[0071] Therefore, the infrared sensor 10 includes a pyroelectric infrared sensor, so that it can detect whether a person approaches with low energy consumption, thereby reducing the operating energy consumption of the unlocking system 100.

[0072] See also Figure 4 and Figure 6 In some embodiments, the unlocking system 100 further includes a focusing lens, and the infrared sensor 10 further includes an infrared receiver. The focusing lens corresponds to the infrared receiver, so that the infrared rays reflected by the person pass through the focusing lens and enter the infrared receiver.

[0073] Specifically, the infrared receiver of infrared sensor 10 is primarily used to collect infrared light reflected by a person. A corresponding focusing lens can be provided on the outer surface of the infrared receiver to allow the infrared light reflected by the person to pass through the focusing lens and enter the infrared receiver. The focusing lens can collimate or focus the infrared light reflected by the person so that it enters the infrared receiver, achieving a focused effect. This focusing lens enhances the infrared receiver's sensitivity to infrared radiation, thereby increasing the detection range of infrared sensor 10 and enabling the infrared sensor 10 to promptly detect the approach of a person.

[0074] For example, the focusing lens is a Fresnel lens. A Fresnel lens is an optical device that has a good energy focusing effect. It can be made of cheap, high-density polypropylene material, making it relatively lightweight. The outside of the Fresnel lens is relatively smooth, while the inside is composed of concentric circles from shallow to deep, from inside to outside, and its cross section is jagged. Its focusing principle is as follows: Figure 7 A specific type of Fresnel lens can be installed in front of the infrared receiver of the infrared sensor 10, such as a pyroelectric probe, to focus the thermal infrared radiation source, greatly improving the detection distance of the thermal radiation, thereby increasing the detection area of the pyroelectric infrared sensor and the sensing capability of infrared radiation.

[0076] Specifically, the near-field communication module 20 includes an antenna board 21 and a near-field communication chip 22. The antenna board 21 can be used to receive and transmit NFC signals. The near-field communication chip 22 is responsible for processing the data received by the antenna board 21, performing decryption, verification, and necessary processing, and then passing the data to the application or storing it. The unlocking system 100 may include a mainboard 50 and a housing 40. The near-field communication chip 22 and the controller 30 are integrated on the mainboard 50. The housing 40 has a cavity inside to accommodate the various components of the unlocking system 100. The antenna board 21 and the mainboard 50 are installed in the cavity of the housing 40, so that the housing 40 protects the antenna board 21 and the mainboard 50. In particular, the housing 40 can be divided into an upper shell 41 and a lower shell 42. The upper shell 41 and the lower shell 42 are detachably connected to facilitate the installation of the antenna board 21 and the mainboard 50 in the cavity. At the same time, the antenna board 21 can be connected to the mainboard 50 to secure the antenna board 21 and the mainboard 50.

[0077] In certain embodiments, the unlocking system 100 may also include a wiring harness and a waterproof male connector. The wiring harness is connected to the waterproof male connector and is also connected to the mainboard 50. This allows the wiring harness to connect the electrical components on the mainboard 50 with other electronic systems or components of the vehicle 1000, ensuring smooth transmission of electrical signals. The waterproof male connector utilizes special sealing and waterproof features, such as rubber seals, silicone padding, and a waterproof coating, to ensure a good electrical connection even in harsh environments such as damp and dusty conditions.

[0078] See also Figure 4 and Figure 8In some embodiments, the unlocking system 100 further includes an insulating member 60 , which is located between the antenna board 21 and the main board 50 .

[0079] Specifically, antenna board 21 is a device specifically designed to radiate and receive electromagnetic waves. When current passes through antenna board 21, it generates varying electric and magnetic fields. These varying electric and magnetic fields fluctuate over time, resulting in the radiation of electromagnetic waves. The electromagnetic waves generated by antenna board 21 may interfere with electrical components on mainboard 50, such as near-field communication chip 22 and controller 30.

[0080] The insulator 60 is a component capable of absorbing and absorbing electromagnetic waves. For example, the insulator 60 comprises ferrite. Providing the insulator 60 between the antenna board 21 and the mainboard 50 effectively absorbs and attenuates high-frequency electromagnetic waves that may be generated between the antenna board 21 and the mainboard 50, thereby preventing these electromagnetic waves from interfering with the electrical components on the mainboard 50. This ensures the normal operation of the electrical components on the mainboard 50, particularly the near-field communication chip 22 and the controller 30.

[0081] See also Figure 4 In some embodiments, after the infrared sensor 10 detects a person for the first time, if the infrared sensor 10 detects a person again after a preset delay, the controller 30 wakes up the near field communication module 20.

[0082] In other embodiments, after the infrared sensor 10 detects a person for the first time, if the infrared sensor 10 delays for a preset period of time without detecting a person, the controller 30 enters a sleep state.

[0083] Specifically, the infrared sensor 10 performs delayed detection based on a preset time length, which is an optimal time length for determining whether the detected person has a tendency to approach the unlocking system 100 .

[0084] After the infrared sensor 10 detects a person for the first time, if the infrared sensor 10 detects a person after a preset delay, it can be considered that the detected person has a tendency to approach the unlocking system 100, and it is likely that the person is a user and has a high probability of unlocking. At this time, the near field communication module 20 can be awakened to ensure that the user can successfully complete the unlocking through the near field communication module 20. For example Figure 9 The area between the two straight lines is the detection area of infrared sensor 10. When a person is within this area, infrared sensor 10 detects a person. The arrows indicate the person's walking direction. The two people are two detection results of infrared sensor 10, respectively. It can be seen that the person is within the detection range in both detections. This means that after the infrared sensor 10 detects a person for the first time, it can also detect a person after a delayed detection. At this time, controller 30 wakes up near-field communication module 20.

[0085] For example, when the car owner passes by at a distance of 3-5 meters in front of the vehicle 1000, the PIR detects the temperature change in the detection area for the first time, and outputs a high level to trigger the wake-up controller 30. After a delay of 1 second, the car owner continues to approach the PIR detection area, and the PIR continues to output a high level. The controller 30 can determine that the car owner is approaching the rearview mirror 400, immediately wake up the near-field communication module 20, and perform the Polling opening action, preparing to communicate with the car owner's mobile phone NFC.

[0086] After the infrared sensor 10 detects a person for the first time, if the infrared sensor 10 does not detect a person after a preset delay, it can be considered that the detected person is just passing by and has no need to unlock the car. At this time, the controller 30 re-enters the sleep state. At the same time, the near-field communication module 20 is always in the sleep state during this process to reduce unnecessary energy consumption of the near-field communication module 20. After the controller 30 enters the sleep state, the infrared sensor 10 continues to monitor the temperature changes around the vehicle 1000 so as to detect the presence of a person immediately. For example Figure 10 It can be seen that the infrared sensor 10 can detect a person only during the first detection, and the detection result of the delayed detection is that there is no person. At this time, the controller 30 enters the sleep state.

[0087] For example, when someone (not the car owner) passes laterally at a distance of 3-5 meters in front of the vehicle 1000 (with the PIR installation position of the rearview mirror 400 as the reference point), but does not approach the rearview mirror 400, the PIR detects the temperature change in the detection area for the first time, and outputs a high level to trigger the wake-up controller 30. After a delay of 1s, the pedestrian has moved away from the PIR detection area, and the PIR outputs a low level. The controller 30 determines that the pedestrian is not approaching the rearview mirror 400 at this time, and will not wake up the near-field communication module 20. The controller 30 continues to sleep, and the PIR continues to monitor the temperature changes around the vehicle 1000.

[0088] Among them, the preset time length can be one or more, and there is no restriction here. For example, the preset time length is 1 second, and after the infrared sensor 10 detects a person for the first time, it can detect whether there is a person again after a delay of 1 second. For another example, if the preset time length is multiple, the infrared sensor 10 can perform multiple delayed detections according to multiple preset time lengths. For example, the preset time lengths are 1 second, 3 seconds and 5 seconds respectively, then the infrared sensor 10 can detect again 1 second, 3 seconds and 5 seconds after the first detection of a person. If a person is detected in these three detections, it can be considered that the person has been staying in the detection range of the infrared sensor 10, and the detected person has a tendency to approach the unlocking system 100. In the case of multiple preset time lengths, as long as the detection result corresponding to the last preset time length shows that no person is detected, it can be considered that the detected person just happened to pass by and there is no need to unlock. At this time, the controller 30 re-enters the sleep state.

[0089] In this way, the infrared sensor 10 can accurately determine whether a person entering the detection range is approaching the unlocking system 100 through delayed detection. Only when it is determined that the person is approaching the unlocking system 100 will the near-field communication module 20 be awakened. This avoids unnecessary energy consumption of the near-field communication module 20.

[0090] In some further embodiments, when the infrared sensor 10 detects the presence of a person, the controller 30 may immediately wake up the near field communication module 20 without delaying detection, to ensure that the near field communication module 20 can be woken up in a timely manner.

[0091] See also Figure 4 In some embodiments, when it is detected that the vehicle 1000 is started, the controller 30, the infrared sensor 10 and the near field communication module 20 all enter a dormant state.

[0092] Specifically, when it is detected that the vehicle 1000 is started, it can be considered that the vehicle 1000 will not need to be unlocked or locked at this time. At this time, the controller 30, the infrared sensor 10 and the near-field communication module 20 can all enter a sleep state to reduce unnecessary energy consumption of the controller 30, the infrared sensor 10 and the near-field communication module 20.

[0093] See also Figure 4 In some embodiments, when the vehicle 1000 is in a parking state and the main driving door is opened, the processor 300 of the vehicle 1000 wakes up the controller 30 to wake up the near field communication module 20 and the infrared sensor 10.

[0094] Specifically, the processor 300 of the vehicle 1000 can detect whether the vehicle 1000 is in a parking state or a driving state, which can be determined specifically based on the gear position or the state of the parking brake. At the same time, the processor 300 of the vehicle 1000 can also be provided with a corresponding sensor to determine whether the main driving door is opened.

[0095] When vehicle 1000 is parked and the driver's door is open, it can be assumed that the driver needs to exit the vehicle and may require the vehicle to lock. Therefore, the processor 300 of vehicle 1000 wakes up the controller 30, which in turn wakes up the near-field communication module 20 and infrared sensor 10. The awakened infrared sensor 10 can be used to detect whether the driver has left vehicle 1000. It can also monitor the area near vehicle 1000 when the electronic lock 200 is locked, thereby promptly detecting any approaching persons. The near-field communication module 20 can be used to communicate with a user's (including the driver's) communication device to promptly receive user instructions.

[0096] In this way, after the driver gets off the vehicle, the processor 300 can promptly wake up the controller 30 , the near field communication module 20 and the infrared sensor 10 , so that the driver can use his communication device to complete the closing of the electronic lock 200 .

[0097] See also Figure 4 In some embodiments, when the vehicle 1000 is in a parking state and the main driving door is opened, the controller 30 wakes up the infrared sensor 10; when the controller 30 determines that a person at the main driving door has gotten off the vehicle based on the detection result of the infrared sensor 10, the controller 30 wakes up the near-field communication module 20.

[0098] Specifically, the infrared sensor 10 can effectively sense moving heat sources within a designated area. Therefore, the controller 30 can determine the human body's motion state based on the infrared sensor 10's detection results, i.e., the heat source conditions within the detection range, and thereby determine whether the driver has exited the vehicle. Alternatively, the infrared sensor 10 can determine whether the driver has exited the vehicle based on its own detection results and then transmit this information to the controller 30.

[0099] When vehicle 1000 is parked and the main driver's door is opened, controller 30 may first wake up infrared sensor 10 to determine whether the driver, that is, the driver, has exited the vehicle. If the driver has exited the vehicle, it can be assumed that the driver has requested a lock. Controller 30 will then wake up near-field communication module 20 to facilitate communication with the driver's communication device. If the driver has not exited the vehicle, it can be assumed that the driver has no request to lock the vehicle. Controller 30 will not wake up near-field communication module 20 to reduce unnecessary energy consumption by the near-field communication module 20.

[0100] In this way, when the vehicle 1000 is parked and the main driving door is opened, the controller 30 can wake up the infrared sensor 10 and the near-field communication module 20 in sequence according to the current situation after being awakened, ensuring that the near-field communication module 20 is awakened after the driver gets off the vehicle, so as to reduce unnecessary energy consumption of the near-field communication module 20.

[0101] Of course, in other embodiments, the infrared sensor 10 and the near field communication module 20 may be awakened immediately after the controller 30 is awakened, thereby ensuring that the driver's instructions can be obtained in a timely manner.

[0102] See also Figure 4 In some embodiments, when the near field communication module 20 communicates with the communication device, the controller 30 sends a locking signal to the processor 300 of the vehicle 1000 to close the electronic lock 200 of the vehicle 1000 .

[0103] Specifically, when vehicle 1000 is parked and the driver's door is opened, controller 30, infrared sensor 10, and near-field communication module 20 are sequentially activated. When near-field communication module 20 communicates with the user's communication device, it can be assumed that the user has issued a lock instruction. At this point, controller 30 can send a lock signal to processor 300 of vehicle 1000 to close electronic lock 200 of vehicle 1000.

[0104] See also Figure 4 In some embodiments, when the near-field communication module 20 communicates with the communication device, after the infrared sensor 10 detects that no person is detected for the first time, if the infrared sensor 10 detects that no person is detected within the first preset delay period, the controller 30 and the near-field communication module 20 enter the sleep mode.

[0105] Specifically, when the vehicle 1000 is parked and the near field communication module 20 is communicating with the communication device, it can be considered that the electronic lock 200 has completed the locking action.

[0106] The first preset delay period is a delay period, which is used to prevent a person from locking and leaving the vehicle 1000 and then returning to the vehicle 1000 to unlock it within a short period of time, causing the near-field communication module 20 and the controller 30 to frequently wake up and sleep. For example, the first preset delay period is 5-10 seconds. When the near-field communication module 20 is communicating with the communication device, after the infrared sensor 10 detects no person for the first time, it can be considered that the user has left the vehicle 1000. If the infrared sensor 10 detects no person within the first preset delay period, it can be considered that the possibility of the user returning to the vehicle 1000 again in a short period of time is small, and at this time the controller 30 and the near-field communication module 20 enter the sleep mode. If a detection result within the first preset delay period is that a person is detected, it can be considered that the possibility of the user returning to the vehicle 1000 is large, and the controller 30 and the near-field communication module 20 can maintain the working state.

[0107] For example, the electronic lock 300 is the door lock of the vehicle 1000. When the owner parks the vehicle and attempts to open the main driving door, the controller 30 is awakened by the processor 300 in the vehicle, and the PIR is activated. When the owner is detected to have exited the vehicle, the PIR outputs a high level, triggering the controller 30. The controller 30 immediately wakes up the near-field communication module 20 and performs a polling start action, preparing to communicate with the owner's mobile phone via NFC to lock the vehicle. After the NFC communication is completed and the PIR detects that the owner has moved away from the rearview mirror 400, the controller 30 delays for another 5-10 seconds to confirm that the owner is not approaching the vehicle 1000, i.e., shuts off the NFC field. The controller 30 and the near-field communication module 20 enter a low-power sleep mode, while the PIR continues to monitor the temperature changes around the vehicle 1000.

[0108] In this way, a first preset delay period can be set to determine whether a person needs to return to the vehicle 1000 to unlock it. If the infrared sensor 10 does not detect a person during this period, the controller 30 and the near-field communication module 20 will enter the sleep mode again to prevent the user from returning to the vehicle 1000 to unlock it within a short period of time after locking, thereby ensuring that the near-field communication module 20 and the controller 30 will not be started or dormant multiple times in a short period of time.

[0109] See also Figure 4 In some embodiments, after the near-field communication module 20 is awakened, if the near-field communication module 20 does not communicate with the communication device within the second preset delay period and the electronic lock 200 is in a locked state, then after the infrared sensor 10 detects that no person is detected for the first time, if the infrared sensor 10 detects that no person is detected within the third preset delay period, the controller 30 and the near-field communication module 20 enter the sleep mode.

[0110] Specifically, the user may also lock the electronic lock 200 by other means, such as using Bluetooth or UWB sensorless locking. The second preset delay period corresponds to the longest duration of time the user has locked the electronic lock 200 by other means after exiting the vehicle. If the electronic lock 200 remains locked within the second preset delay period, it can be assumed that the user locked the electronic lock 200 by other means after exiting the vehicle.

[0111] The controller 30 can determine whether the electronic lock 200 has transitioned from an unlocked state to a locked state. The processor 300 can determine that the electronic lock 200 has transitioned from an unlocked state to a locked state. In this case, the processor 300 can send a lock signal to the controller 30. Upon receiving the lock signal, the controller 30 can determine that the electronic lock 200 has transitioned from an unlocked state to a locked state. In other words, the controller 30 can determine that the electronic lock 200 has transitioned from an unlocked state to a locked state based on the lock signal from the processor 300 of the vehicle 1000.

[0112] The third preset delay period is a delay period designed to prevent a person from locking and leaving the vehicle 1000 and then returning to unlock it within a short period of time, which would cause the NFC module 20 and controller 30 to frequently wake up and go back to sleep. If the NFC module 20 does not communicate with the communication device during the second preset delay period, and the controller 30 determines, based on information from the processor 300, that the electronic lock 200 is locked, the controller 30 will continue to delay according to the third preset delay period. After the infrared sensor 10 detects no person for the first time, it can be assumed that the user has left the vehicle 1000. If the infrared sensor 10 detects no person within the third preset delay period, it is considered unlikely that the user will return to the vehicle 1000 within a short period of time. In this case, the controller 30 will control the NFC module 20 to enter sleep mode, and the controller 30 itself will also enter sleep mode. If a detection result is detected at any time within the third preset delay period, it can be considered likely that the user has returned to the vehicle 1000, and the controller 30 and NFC module 20 can remain operational.

[0113] For example, the electronic lock 300 is the door lock of vehicle 1000. The second preset delay period is 10-20 seconds, and the third preset delay period is 5-10 seconds. When the vehicle owner parks the vehicle and attempts to open the main driving door, the controller 30 is awakened by the processor 300 in the vehicle, and the PIR is activated. The PIR detects that the vehicle owner has exited the vehicle and outputs a high level to trigger the controller 30. The controller 30 then awakens the near-field communication module 20 and performs the polling opening action. However, within 10-20 seconds, the controller 30 does not detect that the vehicle owner's mobile phone is communicating with the near-field communication module 20 to lock the vehicle. During this stage, if the processor 300 notifies the vehicle 1000 that it is locked and the PIR detects that the vehicle owner has moved away from the rearview mirror 400, the controller 30 delays another 5-10 seconds to confirm that the vehicle owner is not approaching the vehicle 1000, thus shutting down the NFC field. The controller 30 and the near-field communication module 20 enter a low-power sleep mode, while the PIR continues to monitor temperature changes around the vehicle 1000.

[0114] In this way, it can be ensured that when the user uses other methods to lock the vehicle, the controller 30 and the near field communication module 20 can also obtain the information and enter the sleep mode when appropriate.

[0115] See also Figure 4 In some embodiments, after the near-field communication module 20 is awakened, if the near-field communication module 20 does not communicate with the communication device within the second preset delay period, the electronic lock 200 is in the unlocked state, and the controller 30 sends a check prompt signal to the processor 300, so that the processor 300 notifies the preset user to check and confirm whether the vehicle 1000 is locked.

[0116] Specifically, the processor 300 may establish a communication link with a preset user, such as a driver's communication device, in advance, so as to send information to the preset user.

[0117] After the NFC module 20 is awakened, if it does not communicate with the communication device within the second preset delay period and the electronic lock 200 is unlocked, it can be assumed that the driver may have forgotten to lock the car. Therefore, in this case, the controller 30 can send a check prompt signal to the processor 300. Upon receiving the check prompt signal, the processor 300 can activate the cloud service function to remotely notify a preset user, such as the driver, to check and confirm whether the electronic lock 200 is locked.

[0118] For example, the second preset delay period is 10-20 seconds. After the near-field communication module 20 is awakened, the controller 30 delays for another 10-20 seconds. During this time period, the controller 30 continuously obtains information about whether the electronic lock 200 is locked. If the electronic lock 200 is not detected as locked during this time period, the controller 30 sends a check prompt signal to the processor 300. If the electronic lock 200 is detected as locked during this time period, the above-mentioned process after the electronic lock 200 is locked is executed.

[0119] In this way, the unlocking system 100 also has the function of reminding the preset user to lock the vehicle 1000, so as to enhance the anti-theft performance of the vehicle 1000.

[0120] See also Figure 4 In some embodiments, during the second preset delay period when the near-field communication module 20 is awakened, if the near-field communication module 20 does not communicate with the communication device and the electronic lock 200 is in an unlocked state, then when the detection result of the infrared sensor 10 is that no person is detected, the controller 30 sends a check prompt signal to the processor 300, so that the processor 300 notifies the preset user to check and confirm whether the vehicle 1000 is locked.

[0121] Specifically, if the infrared sensor 10 detects a person and the electronic lock 200 is unlocked during the second preset delay period after the near-field communication module 20 is awakened, it can be assumed that the user has not left the vehicle 1000 and has not yet requested to lock the vehicle. If the electronic lock 200 remains unlocked throughout the second preset delay period, and the infrared sensor 10 detects no person at the end of the second preset delay period, it can be assumed that the user has left and may have forgotten to lock the vehicle. Therefore, at this time, the controller 30 can send a check prompt signal to the processor 300. Upon receiving the check prompt signal, the processor 300 can activate the cloud service function to remotely notify a preset user, such as the driver, to check and confirm whether the electronic lock 200 is locked.

[0122] For example, the electronic lock 300 is the door lock of the vehicle 1000. If the controller 30 does not detect the user's communication device communicating with the near-field communication module 20 to lock the vehicle within 10-20 seconds, and does not receive the vehicle lock information transmitted by the processor 300, and the PIR detects that the user is away from the rearview mirror 400, the controller 30 will instruct the processor 300 to activate the cloud service function and remotely notify the user to check and confirm whether the vehicle 1000 is locked.

[0123] In this way, the controller 30 can remind the preset user to lock the vehicle when it is determined that the user is away from the vehicle 1000, that is, when the user is likely to forget to lock the vehicle, the controller 30 can remind the preset user to lock the vehicle, thereby improving the user experience.

[0124] See also Figure 4 In some embodiments, within the fourth preset delay period after the inspection prompt signal is issued, if the detection results of the infrared sensor 10 are all no people are detected, the near field communication module 20 and the controller 30 enter the sleep state.

[0125] Specifically, the third preset delay period is a time delay period, for example, 5-10 seconds, to ensure that the NFC module 20 remains operational and can immediately communicate with the user's communication device after the user receives the notification and returns to the vehicle 1000 to unlock the vehicle. If the infrared sensor 10 detects no one approaching during the third preset delay period, it is assumed that the user does not need to lock the vehicle. The NFC module 20 and controller 30 then enter a dormant state, thereby reducing unnecessary energy consumption by the NFC module 20 and controller 30.

[0126] See also Figure 4 In some embodiments, within the fourth preset delay period after the inspection prompt signal is issued, if the detection result of the infrared sensor 10 is that a person is detected, the near-field communication module 20 and the controller 30 maintain the current state until the electronic lock 200 is switched to a locked state.

[0127] Specifically, within the fourth preset delay period after the check prompt signal is issued, if the infrared sensor 10 detects a person approaching, that is, if the infrared sensor 10 detects a person approaching at a certain moment, it can be assumed that the user has returned to the vehicle 1000 to lock the vehicle. At this time, the near-field communication module 20 and the controller 30 are controlled to maintain their current state, that is, to remain open, until the electronic lock 200 switches to the locked state. After the electronic lock 200 switches to the locked state, the controller 30 and the near-field communication module 20 enter a dormant state to reduce unnecessary energy consumption by the controller 30 and the near-field communication module 20.

[0128] For example, the third preset delay period is 5-10 seconds. After the controller 30 issues the check prompt signal, the controller 30 delays for another 5-10 seconds to confirm that the vehicle owner is not approaching the vehicle 1000, and then turns off the NFC field. If the vehicle owner is detected approaching the vehicle 1000, the NFC field remains on, and the NFC field is turned off again after the vehicle owner locks the vehicle. The controller 30 and the near-field communication module 20 re-enter the low-power sleep mode, and the PIR continues to monitor the temperature changes around the vehicle 1000.

[0129] In this way, it can be ensured that a delay is also performed after the inspection reminder signal is issued. If a person is detected within the delay time, the near-field communication module 20 and the controller 30 will remain turned on. If no person is detected within the delay time, the controller 30 and the near-field communication module 20 will enter the sleep state again. On the one hand, when the user sees the notification sent by the processor 300 and returns to the vehicle 1000, the near-field communication module 20 can communicate quickly with the user's communication device. On the other hand, it is convenient to reduce unnecessary energy consumption of the controller 30 and the near-field communication module 20.

[0130] See also Figure 4 An embodiment of the present application provides a vehicle 1000, which includes an electronic lock 200, an unlocking system 100 of any one of the above embodiments, and a processor 300. The processor 300 is communicatively connected to the controller 30 of the unlocking system 100 to control the opening of the electronic lock 200 according to the unlocking signal sent by the controller 30.

[0131] Specifically, the electronic lock 200 controls the operation of the circuit or chip, thereby controlling the closing of the mechanical switch to achieve unlocking and locking functions, through electronic means such as password input, card swiping, fingerprint, and Bluetooth. The processor 300 is the main control of the vehicle 1000. It can communicate with the unlocking system 100 and control the unlocking and locking of the electronic lock 200. The processor 300 can control the opening of the electronic lock 200 based on the unlock signal sent by the controller 30, and the processor 300 is also used to control the closing of the electronic lock 200 based on the locking signal sent by the unlocking system 100.

[0132] The electronic lock 200 may be installed at any position of the vehicle 1000 , for example, at a vehicle door, so as to control the unlocking and locking of the vehicle door using NFC.

[0133] The unlocking system 100 can be installed at any position of the vehicle 1000 , but it is necessary to ensure that the personnel's communication equipment can communicate smoothly with the unlocking system 100 . Therefore, the unlocking system 100 is usually installed at a position close to the surface of the vehicle 1000 , for example, inside the rearview mirror 400 of the vehicle 1000 .

[0134] In certain embodiments, the detection range of the infrared sensor 10 is determined based on the vehicle owner's walking range when approaching the vehicle 1000. The detection range of the infrared sensor 10 and the vehicle owner's walking range when approaching the vehicle 1000 must at least partially overlap. For example, the infrared sensor 10 may be located on the side of the rearview mirror 400 near the front of the vehicle, i.e., facing directly in front of the vehicle 1000. This ensures that when the vehicle owner approaches the vehicle 1000 and wishes to unlock the vehicle, the infrared sensor 10 can quickly detect the vehicle owner's approach, thereby ensuring that the controller 30 and the near-field communication module 20 are promptly awakened, and that the vehicle owner's communication device can communicate smoothly with the near-field communication module 20.

[0135] When no one approaches vehicle 1000, the controller 30 and near-field communication module 20 are both in a dormant state, with only the infrared sensor 10 in operation, significantly reducing the energy consumption of the unlocking system 100. The infrared sensor 10 continuously detects whether a person is approaching vehicle 1000. If a person is detected approaching, it can be assumed that the person has requested unlocking. The infrared sensor 10 then wakes up the controller 30, for example by outputting a high level signal to the controller 30. The controller 30 then wakes up the near-field communication module 20. Once awakened, the near-field communication module 20 enters an operating mode, emitting strong signal pulses to communicate with the user's communication device. If the near-field communication module 20 communicates with the user's communication device, it is assumed that the user has entered an unlock command. The controller 30 then sends an unlock signal to the processor 300 of vehicle 1000. Upon receiving the unlock signal, the processor 300 of vehicle 1000 unlocks the electronic lock 200 of vehicle 1000. This completes the unlocking of the electronic lock 200 of vehicle 1000.

[0136] Conversely, when vehicle 1000 is parked and the driver's door is opened, controller 30, infrared sensor 10, and near-field communication module 20 are sequentially activated. When near-field communication module 20 communicates with the user's communication device, it can be assumed that the user has issued a lock instruction. At this point, controller 30 can send a lock signal to processor 300 of vehicle 1000. Upon receiving the lock signal, processor 300 closes electronic lock 200 of vehicle 1000.

[0137] The unlocking system 100 for a vehicle 1000 according to an embodiment of the present application comprises an infrared sensor 10, a near-field communication module 20, and a controller 30. When the electronic lock 200 of the vehicle 1000 is locked and detects a person, the infrared sensor 10 can wake up the controller 30, which then wakes up the near-field communication module 20. After waking up, the near-field communication module 20 enters an operating mode, emitting strong signal pulses to communicate with the user's communication device. While the near-field communication module 20 is communicating with the user's communication device, the controller 30 can send an unlocking signal to the processor 300 of the vehicle 1000. Upon receiving the unlocking signal, the processor 300 of the vehicle 1000 unlocks the electronic lock 200 of the vehicle 1000, thereby completing the unlocking of the electronic lock 200 of the vehicle 1000. This way, when no one is near the vehicle 1000, the controller 30 and the near-field communication module 20 are both in a dormant state, leaving only the infrared sensor 10 in an active state, significantly reducing the energy consumption of the unlocking system 100. At the same time, the infrared sensor 10 of the present application can detect the approach of a human body at a relatively long distance. Therefore, when the user approaches the unlocking system 100, the near-field communication module 20 has entered the working mode and can emit a strong communication signal field to communicate with the user's communication device. It can be understood that at this time, even if the card swipe sensing distance is far, the user's communication device can still be recognized by the near-field communication module 20, thereby improving the user experience. In this way, the present application can balance energy consumption and card swipe sensing distance.
