Description

Technical Field

[0001] The present invention relates to the technical field of vehicle communication, and specifically provides a control method and system for a vehicle NFC communication module, and a vehicle. Background Art

[0002] Vehicles with NFC key unlocking function significantly improve the user's travel experience. By using mobile phones or other NFC devices as keys, the convenience of use is greatly improved, so that users no longer need to worry about forgetting to bring keys or losing keys.

[0003] However, vehicles equipped with NFC function will increase the electric and magnetic field radiation of the vehicle, which may easily cause it to fail to meet the national standard GB / T 18387-2017. Specifically, the national standard GB / T18387-2017 test requires that the external radiation of the whole vehicle does not exceed the standard limit when the vehicle speed is 16km / h, 40km / h, and 70km / h. The working frequency band of NFC is usually fixed during design, and the working frequency band is selected at 13.56MHz, so that NFC technology can achieve simple communication and data transmission between devices within a short distance, while having high transmission speed and security. The NFC working frequency band of 13.56MHz is in the frequency band required by the GB / T 18387-2017 test, and the transmission power is generally designed to be high. If the NFC is set close to the side of the vehicle and close to the outside, the GB / T18387-2017 test will exceed the standard; that is, vehicles equipped with NFC with a working frequency band of 13.56MHz will have radiation exceeding the standard.

[0004] The existing technology usually adopts solutions such as reducing the transmission power of the NFC reader or using circuit filtering and shielding to solve the above problems, but these solutions will reduce the NFC transmission power and affect the card swiping performance, giving users a poor experience. At the same time, adding filtering will increase costs to varying degrees.

[0005] In summary, existing vehicles sacrifice vehicle NFC performance to meet the national standard GB / T 18387-2017, which affects user experience and is costly.

[0006] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention

[0038] Figure 4 It is a flowchart of determining whether a vehicle is in a driving state according to a third preferred embodiment of the present invention. DETAILED DESCRIPTION

[0039] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0040] It should be noted that in the description of the present invention, "module" may include hardware, software or a combination of both. A module may include hardware circuits, various suitable sensors, communication ports, and memories, and may also include software parts, such as program codes, or a combination of software and hardware. The term "A and / or B" means all possible combinations of A and B, such as only A, only B, or A and B.

[0041] In order to solve the problem of excessive NFC radiation in the prior art mentioned in the background technology, the prior art usually adopts solutions such as reducing the transmission power of the NFC reader or adopting circuit filtering and shielding, but these solutions will reduce the NFC transmission power and affect the card swiping performance, bringing a poor user experience. At the same time, increasing the filtering will increase the cost to varying degrees. The present invention provides a solution different from the prior art, which can meet the national standard GB / T 18387-2017 without sacrificing NFC performance and without additional cost.

[0042] See first Figure 1 ,like Figure 1 As shown, the main steps of the vehicle NFC communication module of the present invention include:

[0043] Step S1: Obtain vehicle information;

[0044] Step S2: determining whether the vehicle is in a driving state based on vehicle information;

[0045] Step S3: Control the NFC communication module to turn off;

[0046] Step S4: Control the NFC communication module to turn on.

[0047] In step S1, vehicle information can be obtained through the vehicle VCU control unit. The vehicle information can be vehicle speed information and gear information, or only vehicle speed information, or only gear information. Technical personnel in this field can set it according to actual conditions.

[0048] In step S2, if the vehicle is in a driving state, step S3 is executed; if the vehicle is in a non-driving state, step S4 is executed; specifically, in step S2, the NFC control module can determine whether the vehicle is in a driving state based on the acquired vehicle information. If the vehicle is in a driving state, the driving state means that the vehicle is in motion or the vehicle is unlocked. At this time, the vehicle does not need the NFC function, so step S3 is executed to control the NFC communication module to turn off, reduce radiation, reduce the energy consumption of the entire vehicle and improve the vehicle's endurance. If the vehicle is in a non-driving state, the non-driving state means that the vehicle is stationary or the vehicle is not unlocked or locked when stationary. At this time, the vehicle needs to be unlocked or locked by swiping an NFC card, and the vehicle needs the NFC function, so step S4 is executed to control the NFC communication module to turn on, and the NFC communication module is turned on in the non-driving state for unlocking or locking the vehicle by swiping an NFC card.

[0049] Compared with the prior art, the control method of the present invention is highly flexible and practical. While meeting the national standard GB / T 18387-2017, it is applicable to NFC technologies of various operating frequencies, without reducing NFC performance or adjusting NFC transmission power, thus ensuring a smooth experience for users when unlocking and locking the vehicle by swiping the NFC card. At the same time, the method does not require additional costs during implementation, effectively reduces the energy consumption of the entire vehicle, reduces the working time of the NFC communication module, and further extends the service life of the NFC communication module.

[0050] The control method of the present invention can achieve the above-mentioned technical effects by only including step S1, step S2 and step S3. In other embodiments, step S1, step S2 and step S3 are included, but step S4 is not included. When the result of step S2 is judged to be in a non-driving state, the user can operate whether to turn on the NFC communication module, or other control methods can be used. Those skilled in the art can set it according to actual conditions.

[0051] See next Figure 2 ,like Figure 2 As shown, the specific steps of determining the driving state of the first preferred embodiment of the present invention are as follows:

[0052] Step S11: obtaining vehicle gear information and vehicle speed information;

[0053] Step S12: determining whether the vehicle is in a driving state based on the gear information and the vehicle speed information;

[0054] Step S121: if the gear information is not the P gear and the vehicle speed information is the vehicle speed, it is determined that the vehicle is in the driving state;

[0055] Step S122: if the gear information is not the P gear and the vehicle speed information is no vehicle speed, it is determined that the vehicle is in a driving state;

[0056] Step S123: If the gear position information is P gear and the vehicle speed information is no speed, it is determined that the vehicle is in a non-driving state.

[0057] In step S11, the vehicle gear information and speed information are obtained through the vehicle VCU control unit, that is, the vehicle VCU control unit transmits the vehicle gear information and speed information to the NFC control module, and the NFC control module executes step S12 to determine whether the vehicle is in a driving state based on the gear information and speed information. Step S12 includes step S121, step S122 and step S123.

[0058] In step S121, if the gear information is non-P gear and the vehicle speed information is a speed, it proves that the vehicle is in motion and is judged to be in a driving state. Normally, when the vehicle is stationary and not started, the gear is in P gear. After the driver enters the vehicle and operates the gear shift, the vehicle changes from P gear to non-P gear. At this time, the vehicle is in a driving state and no NFC function is required to unlock and lock the vehicle. Therefore, it is judged to be in a driving state. Afterwards, the NFC communication module is controlled to be turned off based on the judgment result. When driving, the NFC communication module is turned off to reduce the radiation of the whole vehicle and meet the national standard GB / T 18387-2017.

[0059] In step S122, if the gear information is non-P gear and the vehicle speed information is no speed, it is judged that the vehicle is in a driving state. The body information is no speed, but the gear is in a non-P gear, which proves that the driver has entered the vehicle and performed a gear shifting operation. The no speed may be that the driver stepped on the brake to make the vehicle stationary, or the vehicle was stationary in N gear, or it may be in other working conditions. No matter which working condition, as long as the gear is in a non-P gear, it proves that the driver has performed a gear shifting operation. At this time, the vehicle is already in an unlocked state and does not need to be unlocked again. When the vehicle needs to be locked, the vehicle is generally stopped and shifted to P gear after it stops, and then the vehicle is locked. That is, if the vehicle is in a non-P gear, there is no need to lock the vehicle. In summary, when the gear is in a non-P gear and there is no speed, there is no need to swipe the vehicle to unlock and lock the vehicle. Therefore, it is judged to be in a driving state, and then the NFC communication module is controlled to be closed based on the judgment result.

[0060] In step S123, if the gear information is P gear and the vehicle speed information is no speed, it is determined that the vehicle is in a non-driving state. The vehicle gear is in P gear and there is no speed. Generally, the driver has stabilized the vehicle and needs to lock the vehicle, or after the driver locks the vehicle, the gear is still in P gear and there is no speed. The driver needs to use the vehicle and needs to unlock the vehicle again. The vehicle is stationary and in P gear and is in a non-driving state. Then, based on the judgment result, the NFC communication module is controlled to turn on, which is convenient for users to swipe the NFC card to unlock and lock the vehicle.

[0061] The non-P gear can be D gear, R gear, N gear or S gear. Of course, this is not restrictive. On other types of vehicles, it can also be other gears. As long as it is not P gear, it is non-P gear. If there is a vehicle speed, the vehicle speed is greater than 0, and if there is no vehicle speed, the vehicle speed is equal to 0.

[0062] In other embodiments, the step of determining whether the vehicle is in a driving state based on the gear information and the vehicle speed information includes: if the determination condition is satisfied that the gear information is not the P gear or the vehicle speed information is a speed, the determination result is that the vehicle is in a driving state, otherwise, the determination result is that the vehicle is in a non-driving state. Specifically, regardless of the working condition of the vehicle, as long as the vehicle is in the P gear or the vehicle speed is a speed, if one of the two determination conditions is satisfied, the vehicle is determined to be in a driving state, and if neither of the two determination conditions is satisfied, the vehicle is determined to be in a non-driving state.

[0063] See next Figure 3 ,like Figure 3 As shown, the specific steps of determining the driving state of the second preferred embodiment of the present invention are as follows:

[0064] Step S21: obtaining vehicle gear information;

[0065] Step S22: determining whether the vehicle is in a driving state based on the gear information;

[0066] Step S221: if the gear information is not the P gear, it is determined that the vehicle is in a driving state;

[0067] Step S222: If the gear position information is P gear, it is determined that the vehicle is in a non-driving state.

[0068] In step S21, the vehicle gear information is obtained through the vehicle VCU control unit, that is, the vehicle VCU control unit transmits the vehicle gear information to the NFC control module, and the NFC control module executes step S22 to determine whether the vehicle is in a driving state based on the gear information. Step S22 includes step S221 and step S222.

[0069] In step S221, if the gear information is not P gear, it proves that the driver has entered the vehicle and performed the gear shifting operation, and there is no need to unlock and lock the vehicle. Therefore, it is judged to be in the driving state. Then, based on the judgment result, the NFC communication module is controlled to be turned off. In non-P gear, the NFC communication module is turned off regardless of the vehicle speed, thereby reducing the radiation of the entire vehicle, reducing the energy consumption of the entire vehicle, reducing the NFC working time, and increasing the service life of the NFC.

[0070] In step S222, if the gear information is P gear, it is determined that the vehicle is in a non-driving state. P gear is the parking gear. The vehicle is locked after parking or unlocked after locking. The non-driving state corresponds to the activation of the NFC communication module, which is convenient for users to unlock and lock the vehicle.

[0071] See next Figure 4 ,like Figure 4 As shown, the specific steps of determining the driving state of the third preferred embodiment of the present invention are as follows:

[0072] Step S31: obtaining vehicle speed information;

[0073] Step S32: determining whether the vehicle is in a driving state based on the vehicle speed information;

[0074] Step S321: if the vehicle speed information indicates that the vehicle speed is available, it is determined that the vehicle is in a driving state;

[0075] Step S322: If the vehicle speed information indicates that there is no vehicle speed, it is determined that the vehicle is in a non-driving state.

[0076] In step S31, the vehicle speed information is obtained through the vehicle VCU control unit, that is, the vehicle VCU control unit transmits the vehicle speed information to the NFC control module, and the NFC control module executes step S32 to determine whether the vehicle is in a driving state based on the speed information. Step S32 includes step S321 and step S322.

[0077] In step S321, if the vehicle speed information shows that there is a vehicle speed, it proves that the vehicle is in a driving state, the driver has entered the vehicle and performed driving operations on the vehicle, and the vehicle is in driving. There is no need to unlock or lock the vehicle, so it is judged to be in a driving state. Then, based on the judgment result, the NFC communication module is controlled to be turned off to reduce the radiation of the entire vehicle, reduce the energy consumption of the entire vehicle, reduce the NFC working time, and increase the service life of the NFC.

[0078] In step S322, if the vehicle speed information is no speed, it is determined that the vehicle is in a non-driving state. After the vehicle stops, there is no speed. When there is no speed, the vehicle is locked or unlocked after being locked. The non-driving state corresponds to the activation of the NFC communication module, which is convenient for users to unlock and lock the vehicle.

[0079] In addition, in some other embodiments, the control method of the present invention further includes:

[0080] Step S41: if the gear information is P gear and / or the vehicle speed information is no vehicle speed, obtain the driver information on the main driving seat;

[0081] Step S42: If the driver information indicates that there is a driver, determine that the vehicle is in a driving state;

[0082] Step S43: If the driver information indicates that there is no driver, it is determined that the vehicle is in a non-driving state.

[0083] In step S41, if the gear information is P gear and / or the vehicle speed information is no speed, the driver information on the main driving seat can be obtained through an infrared sensor, and the driver information is whether there is a driver. The image can also be obtained through an image acquisition device, and then the image is analyzed to determine whether there is a driver on the main driving seat.

[0084] In step S41, if the driver information shows that there is a driver, step S42 is executed to determine whether the vehicle is in a driving state, and the NFC communication module is controlled to be turned off based on the judgment result. Because there is a driver in the main driver's seat, it proves that the driver has entered the vehicle and there is no need to unlock the vehicle by swiping the NFC card, so the NFC communication module is turned off.

[0085] In step S41, if the driver information shows that there is no driver, it proves that the driver has not entered the vehicle. There may be a need to use NFC card swiping to unlock or lock the vehicle. Therefore, step S43 is executed to determine whether the vehicle is in a non-driving state. Based on the judgment result, the NFC communication module is controlled to turn on to facilitate the user to unlock and lock the vehicle.

[0086] In certain embodiments, a control method for a vehicle NFC communication module includes steps S11, S12, S121, S122, S123, 41, S42, and S43. Step S41 is executed after step S123. Although step S123 determines that the vehicle is in a non-driving state, this judgment result is not output. The judgment result after step S41 is output. It can be understood that, in an embodiment that includes steps S123, 41, S42, and S43 at the same time, the judgment result of step S123 is invalidated, the judgment result after step S41 is executed, and the opening and closing control of the NFC communication module is performed based on the control logic after step S41.

[0087] In certain embodiments, the control method of the vehicle NFC communication module includes step S21, step S22, step S221, step S222, step 41, step S42 and step S43. Step S41 is executed after step S222. Although step S222 determines that the vehicle is in a non-driving state, this judgment result is not output. The judgment result after step S41 is output. It can be understood that, in an embodiment that includes step S222, step 41, step S42 and step S43 at the same time, the judgment result of step S222 is invalid, the judgment result after step S41 is executed, and the opening and closing control of the NFC communication module is performed based on the control logic after step S41.

[0088] In certain embodiments, the control method of the vehicle NFC communication module includes step S31, step S32, step S321, step S322, step 41, step S42 and step S43. Step S41 is executed after step S322. Although step S322 determines that the vehicle is in a non-driving state, this judgment result is not output. The judgment result after step S41 is output. It can be understood that, in an embodiment that includes step S322, step 41, step S42 and step S43 at the same time, the judgment result of step S322 is invalid, the judgment result after step S41 is executed, and the opening and closing control of the NFC communication module is performed based on the control logic after step S41.

[0089] In the embodiment that does not include steps S41 to S43, when the vehicle is stationary or in P gear waiting for a red light or the driver is resting in the vehicle, the NFC communication module is always turned on, which will increase the radiation and energy consumption of the entire vehicle, and the working time of the NFC communication module will be prolonged, thereby reducing its lifespan. The control logic using steps S41 to S43 can adapt to this situation without affecting the user's normal unlocking and locking of the vehicle, and reduces the radiation and energy consumption of the entire vehicle when waiting for a red light or the user is resting in the vehicle, thereby increasing its service life.

[0090] In other embodiments, the vehicle information only includes the driver information, and whether the vehicle is in a driving state is determined based on the driver information. The driver information is whether there is a driver. If there is a driver, the vehicle is determined to be in a driving state; if there is no driver, the vehicle is determined to be in a non-driving state. The driving state controls the NFC communication module to be turned off, and the non-driving state controls the NFC communication module to be turned on.

[0091] use Figure 2 , Figure 3 and Figure 4 The control method of the driving state judgment logic shown is applicable to vehicle NFC card unlocking and locking or other suitable related performances; Figure 3 and Figure 4 The control method of the driving state judgment logic shown is applicable to the vehicle NFC card swiping unlocking, locking, starting or other NFC-related performances.
