[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0043] The Near Field Communication (NFC) card swiping experience of the exterior rearview mirror needs to take into account the card swiping distance and NFC standby power consumption. The current NFC solution has a large standby power consumption and a poor card swiping distance. In order to improve this problem, the pure low power card detection function (Low Power Card Detection, referred to as LPCD) + Flexible Printed Circuit Board (Flexible Printed Circuit Board, referred to as FPCB) solution can significantly improve the standby power consumption of the NFC system, and the card swiping distance for Apple phones is also significantly improved, but the card swiping distance for Android phones becomes worse.

[0044] In order to make the near-field communication system more compatible with mobile phone terminals with different operating systems, an embodiment of the present application proposes an in-vehicle near-field communication system, which can reduce the standby power consumption of NFC and improve the card swiping distance of a first type of mobile phone (such as an Android phone) and a second type of mobile phone (such as an Apple phone).

[0045] Reference Figure 1 As shown, the embodiment of the present application provides a vehicle-mounted near-field communication system 100, comprising:

[0046] A first antenna 101, used to output a first near field communication signal;

[0047] A second antenna 102, for outputting a second near field communication signal;

[0048] NFC module 103, used to output or receive near field communication signals;

[0049] The switching module 104 is used to switch the connection relationship between the NFC module 103 and the first antenna 101 and the second antenna 102, so that the NFC module 103 has a first communication mode and a second communication mode;

[0050] When the NFC module 103 is in the first communication mode, the NFC module 103 outputs a first near field communication signal through the first antenna 101 ; when the NFC module 103 is in the second communication mode, the NFC module 103 outputs a second near field communication signal through the second antenna 102 .

[0051] The embodiment of the present application provides a vehicle-mounted near-field communication system, which switches the connection relationship between the NFC module and the first antenna and the second antenna by setting a switching module, so that the NFC module has a first communication mode and a second communication mode; wherein, when the NFC module is in the first communication mode, the NFC module outputs a first near-field communication signal through the first antenna; when the NFC module is in the second communication mode, the NFC module outputs a second near-field communication signal through the second antenna. Through the above settings, the vehicle-mounted near-field communication system can communicate with at least two types of terminal devices, thereby improving the compatibility of the vehicle-mounted near-field communication system.

[0052] Reference Figure 1 and Figure 2 As shown, in some embodiments, the switching module 104 includes:

[0053] A first switch S1, used for selectively connecting the first end of the first antenna 101 or the first end of the second antenna 102;

[0054] The second switch S2 is used to selectively connect the second end of the first antenna 101 or the second end of the second antenna 102 .

[0055] In some embodiments, the first antenna 101 and the second antenna 102 have different antenna sizes.

[0056] In some embodiments, the first antenna 101 and the second antenna 102 have different outer circle sizes.

[0057] In the hardware circuit, the NFC module may include four ports, namely Rx1, Rx2, Tx1 and Tx2, wherein Rx1 and Rx2 are connected to the first switch S1 and the second switch S2 through a capacitor and a resistor, respectively, Tx1 is connected to the first switch S1 through an inductor, a capacitor and a resistor, and Tx2 is connected to the second switch S2 through an inductor, a capacitor and a resistor. The first switch S1 and the second switch S2 may be implemented by two single-pole double-throw switches.

[0058] The dual antenna is switched using the first switching switch S1 and the second switching switch S2. To reduce the layout area of ​​the dual antenna, a design scheme can be adopted in which a large antenna (equivalent to the aforementioned second antenna 102) is nested in a small antenna (equivalent to the aforementioned first antenna 101). For example, the large antenna and the corresponding switching circuit constitute an Apple mobile phone card swiping system, and the small antenna and another switching circuit constitute an Android mobile phone card swiping system.

[0059] The design of a large antenna (equivalent to the aforementioned second antenna 102) nested in a small antenna (equivalent to the aforementioned first antenna 101) can ensure that the working performance of the two antennas is relatively stable. The two antennas are controlled by time-sharing switches. When the small antenna is working, two single-pole double-throw switches connect the first end and the second end of the small antenna, causing the large antenna port to be suspended, which means that the large antenna loop is disconnected, and no closed-loop coil is formed, so a closed-loop current cannot be formed, and then no reverse eddy current will be generated on the large antenna, and naturally the performance of the small antenna will not be degraded.

[0060] Similarly, when the large antenna is working, the two single-pole double-throw switches connect the first and second ends of the large antenna, causing the small antenna port to be suspended and its antenna loop to be disconnected. No closed loop current and reverse eddy current will be formed on the small antenna, and the performance of the large antenna will not be degraded.

[0061] In some embodiments, the first antenna 101 and the second antenna 102 have overlapping transmission areas.

[0062] In some embodiments, the transmission area of ​​the first antenna 101 is smaller than the transmission area of ​​the second antenna 102 .

[0063] In some embodiments, the transmission area of ​​the first antenna 101 is located inside the transmission area of ​​the second antenna 102 .

[0064] In some embodiments, the first NFC signal includes different pulse waveforms.

[0065] In some embodiments, the first near field communication signal includes: a Polling pulse and a LPCD pulse, wherein the Polling pulse is a polling working mode for information exchange between NFC devices.

[0066] In some embodiments, the second NFC signal includes the same pulse waveform.

[0067] In some embodiments, the second NFC signal comprises: an LPCD pulse.

[0068] Reference Figure 3 As shown in some examples, the large antenna and the corresponding switch circuit form an Apple mobile phone card swiping system, and the software configures its NFC pulse waveform to be pure LPCD. The small antenna and another switch circuit form an Android mobile phone card swiping system, and its NFC pulse waveform is a Polling+LPCD solution. Figure 3 It can be seen that when the NFC pulse waveform is the Polling+LPCD scheme, the induced electromotive force is large, the pulse has a rectangular waveform, and the duration is about 5.1ms. Therefore, the first antenna can be made into a small antenna with a smaller size to realize the near field communication function. When the NFC pulse waveform is pure LPCD, the induced electromotive force is small, and the pulse has almost only one rising edge waveform, and the duration is about 40μs. Therefore, the second antenna is made into a large antenna with a larger size to realize the near field communication function.

[0069] It should be noted that when the Apple phone is in the screen-off standby state, the NFC LPCD waveform detection instruction is always running in the background. Once a weak pulse signal that meets the LPCD time slot requirements is detected in the external environment, the NFC circuit of the Apple phone will be immediately triggered, and a series of pulse waveform signals requesting the in-vehicle NFC device to start NFC communication will be actively sent. After receiving the pulse waveform signal, the in-vehicle NFC device will instantly switch from a low-power state to a polling communication mode, complete NFC information exchange with the Apple device, and execute instructions such as unlocking the door.

[0070] However, Android phones cannot detect LPCD waveforms in low-power states. They can only sense a strong field voltage by getting close enough to the NFC vehicle-mounted device and at a distance where the LPCD signal or Polling is strong enough, thereby waking up the phone's NFC to enter Polling mode, complete information exchange with the vehicle-mounted NFC device, and execute commands such as unlocking the door.

[0071] The near-field communication system provided in the embodiment of the present application utilizes nested large and small antennas in combination with different NFC pulse waveforms, and can be adapted to both Apple and Android mobile phone terminals, achieving a relatively long card swiping distance.

[0072] In some embodiments, the switching module switches the first communication mode and the second communication mode to operate alternately.

[0073] In some embodiments, the NFC module adjusts the calling frequency or calling duration of the first communication mode or the second communication mode according to the number of successful communications in the first communication mode or the second communication mode.

[0074] In some examples, the initial interval for the alternating switching of the two antennas can be set to 500ms. After a certain number of user mobile phone card swiping processes are statistically learned, a certain switch can obtain a higher priority and can drive the NFC antenna circuit that matches the user's mobile phone most of the time. By counting the high and low level control time of the two switches to complete the NFC communication, it is possible to learn and determine the type of user's mobile phone for swiping the card, and iteratively improve the working priority of the corresponding switch link. For example, increasing the working time of a certain switch will reduce the working time of another switch accordingly, so as to achieve a mechanism for more efficient response to the user's mobile phone NFC communication.

[0075] According to another embodiment of the present application, a vehicle-mounted near-field communication method is also provided, which is applied to the vehicle-mounted near-field communication system described in any of the above embodiments, and the contents already described are not repeated here. Figure 4 As shown, the vehicle-mounted near-field communication method provided by the embodiment of the present application includes:

[0076] Step S401, the NFC module outputs a first near field communication signal through a first antenna;

[0077] In step S402, the NFC module outputs a second near field communication signal via a second antenna.

[0078] In some embodiments, the switching module switches the first communication mode and the second communication mode to operate alternately.

[0079] In some embodiments, the first NFC signal includes different pulse waveforms.

[0080] In some embodiments, the first near field communication signal includes: a Polling pulse and a LPCD pulse.

[0081] In some embodiments, the second NFC signal includes the same pulse waveform.

[0082] In some embodiments, the second NFC signal comprises: an LPCD pulse.

[0083] It should be noted that when the Apple phone is in the screen-off standby state, the NFC LPCD waveform detection instruction is always running in the background. Once a weak pulse signal that meets the LPCD time slot requirements is detected in the external environment, the NFC circuit of the Apple phone will be immediately triggered, and a series of pulse waveform signals requesting the in-vehicle NFC device to start NFC communication will be actively sent. After receiving the pulse waveform signal, the in-vehicle NFC device will instantly switch from a low-power state to a polling communication mode, complete NFC information exchange with the Apple device, and execute instructions such as unlocking the door.

[0084] However, Android phones cannot detect LPCD waveforms in low-power states. They can only sense a strong field voltage by getting close enough to the NFC vehicle-mounted device and at a distance where the LPCD signal or Polling is strong enough, thereby waking up the phone's NFC to enter Polling mode, complete information exchange with the vehicle-mounted NFC device, and execute commands such as unlocking the door.

[0085] The near-field communication system provided in the embodiment of the present application utilizes nested large and small antennas in combination with different NFC pulse waveforms, and can be adapted to both Apple and Android mobile phone terminals, achieving a relatively long card swiping distance.

[0086] In some embodiments, the calling frequency of the first communication mode or the second communication mode is adjusted according to the number of successful communications in the first communication mode or the second communication mode.

[0087] In some embodiments, the calling duration of the first communication mode or the second communication mode is adjusted according to the number of successful communications in the first communication mode or the second communication mode.

[0088] When the Apple NFC mobile phone turns off the screen and is relatively close (such as 6cm) to the vehicle-mounted NFC device involved in this application and its equipped NFC antenna (FPCB large antenna with an outer circle size of 70×70mm, and FPCB small antenna with a nested outer circle size of 40×40mm), within 500ms when the small antenna switch is turned on, the transmitting waveform of the vehicle-mounted NFC device can be configured as the first mode Polling+1LPCD+1Polling (interval of 100ms) or the second mode Polling+1LPCD (interval of 100ms). Both of these situations do not satisfy the triggering of the LPCD detection mechanism of the Apple mobile phone. When the 500ms are over, the receiving signal voltage of the vehicle-mounted NFC device does not meet the threshold value, the Polling waveform cannot be started, and the algorithm cannot be triggered to time the small antenna switch, which is counted as one time the Apple mobile phone passes through the vehicle-mounted small antenna, and the door unlocking action cannot be achieved.

[0089] During the 500ms period when the large antenna switch is turned on, if the Apple mobile phone NFC detects two consecutive LPCD waveforms with an interval of 100ms, it will send a Polling pulse within the next 50ms and trigger the on-board NFC device to work in the Polling state. At this time, the algorithm will keep the large antenna switch turned on and start timing until the NFC communication is completed. This is counted as one time that the Apple mobile phone unlocks the door through the on-board large antenna.

[0090] When the Android NFC mobile phone turns off the screen and is relatively close (such as 6 cm) to the vehicle-mounted NFC device involved in this application and its equipped NFC antenna (for example, a large FPCB antenna with an outer circle size of 70×70mm, and a small FPCB antenna with a nested outer circle size of 40×40mm), within 500ms of the operation of the ANT1 switch, the vehicle-mounted NFC device emits a pulse waveform set to 1Polling+1LPCD+1Polling (interval of 100ms) or 2Polling+1LPCD (interval of 100ms). After effectively receiving a Polling waveform, the Android mobile phone starts polling continuously and triggers the vehicle-mounted NFC device to switch to the Polling state. At this time, the algorithm will keep the switch of the small antenna open and start timing until the NFC communication is completed, which is counted as one time that the Android mobile phone unlocks the door via the vehicle-mounted small antenna.

[0091] However, during the 500ms time when the large antenna is turned on, the LPCD waveform energy continuously emitted by the on-board NFC device at an interval of 100ms cannot effectively trigger the NFC function of the Android phone with the screen turned off at a long distance such as 6cm. When the 500ms is over, the on-board NFC device cannot start the Polling waveform and cannot trigger the algorithm to time the switch of the large antenna. It is counted as one time that the Android phone passes through the on-board large antenna and cannot unlock the door.

[0092] Reference Figure 5 As shown, by dynamically counting the time proportion difference of the small antenna and the large antenna controlled by the switch in a period of time (such as a day, a week, etc.) working in the Polling state, the type of the user's mobile terminal can be inferred, and the priority algorithm iteration can be started based on this, which can respond faster and better to the NFC communication of the user terminal, and realize a user experience that gets better and better with each swipe.

[0093] If, based on the user's card swiping habits, it is necessary to detect at 2-3cm whether it is an Apple phone or an Android phone that triggers the in-vehicle NFC device to unlock it, the size of the small antenna and the large antenna can be appropriately reduced proportionally, and the execution mechanism of the entire algorithm can remain unchanged.

When the computer program is executed by a processor, the vehicle-mounted near-field communication method described in any of the above embodiments is implemented.
