[0060] S13: Traverse the calibration characteristic database 8, and when the first characteristic parameter set is similar to any second characteristic parameter set, select the calibration data packet corresponding to the second characteristic parameter set and send it to the mobile terminal 7. Specifically, the similarity judgment standard is that the first characteristic parameter set has the highest value coincidence degree with any second characteristic parameter set.

[0061] Taking the first characteristic parameter set as an example, the example values can be as shown in Table 4 below:

[0067] The first characteristic parameter set and the second characteristic parameter set have the highest numerical coincidence, and it is judged that they are similar.

[0068] In addition, the mobile terminal 7 receives the corresponding calibration data packet, and connects with the vehicle end to verify that the corresponding calibration data packet received by the mobile terminal 7 meets the calibration requirements of the Bluetooth non-inductive unlocking and locking function.

[0069] Optionally, the calibration data packet includes some fixed parameters required by the mobile terminal to execute the unlocking and locking function, for example, the Bluetooth field strength values of each group of second characteristic parameter sets common to the vehicle unlocking area in different directions of the vehicle and the vehicle locking area. Further, the Bluetooth field strength values in the calibration data packet are fixed values, and are the middle values of each Bluetooth field strength value range in the second characteristic parameter set;

[0070] After the mobile terminal receives the corresponding calibration data packet, when the Bluetooth field strength value sent by the mobile terminal is the Bluetooth field strength value of the vehicle unlocking area in the calibration data packet, the vehicle is unlocked; when the Bluetooth field strength value sent by the mobile terminal is the Bluetooth field strength value of the vehicle locking area in the calibration data packet, the vehicle is locked.

[0071] Working principle: the method is used for calibrating the mobile terminal 7, by obtaining a first characteristic parameter set of the mobile terminal 7, the first characteristic parameter set includes: a plurality of first field strength values of the mobile terminal 7 in the car unlocking area, a plurality of second field strength values of the mobile terminal 7 in the car locking area; obtain a calibration characteristic database 8, the calibration characteristic database 8 at least includes: a plurality of second characteristic parameter sets and a calibration data packet corresponding to each second characteristic parameter set; each second characteristic parameter set includes: a first field strength range in the car unlocking area and a second field strength range in the car locking area; traverse the calibration characteristic database 8, when the first characteristic parameter set is similar to any second characteristic parameter set, select the calibration data packet corresponding to the second characteristic parameter set, and send it to the mobile terminal 7. Compared with the prior art, by selecting the second characteristic parameter set similar to the first characteristic parameter set of the mobile terminal 7 in the calibration characteristic database 8, the calibration data packet corresponding to the second characteristic parameter set is sent to the mobile terminal 7, without the need for the mobile terminal 7 to calibrate separately, the calibration period of the Bluetooth key non-inductive unlocking and locking function is shortened.

[0072] In some embodiments, the calibration characteristic database 8 further includes: a mobile terminal model set corresponding to each second characteristic parameter set.

[0073] Specifically, the structure of the calibration characteristic database 8 can also be as shown in Table 6:

[0076] In some embodiments, the step of constructing the calibration characteristic database 8 includes:

[0077] S21: obtaining a second characteristic parameter sequence corresponding to different mobile terminals 7, the second characteristic parameter sequence includes: a plurality of third field strength values of the mobile terminal 7 in the car unlocking area, a plurality of fourth field strength values of the mobile terminal 7 in the car locking area;

[0078] S22: screening the second characteristic parameter sequence that meets the consistency index, constructing a second characteristic parameter set; matching a calibration data packet corresponding to each second characteristic parameter set.

[0079] Reference Figure 4 The flowchart for constructing the calibration characteristic database in this application;

[0080] Among them:

[0081] S21: Obtain a second characteristic parameter sequence corresponding to different mobile terminals 7, which includes a plurality of third field strength values of the mobile terminal 7 in the unlocking area of the vehicle and a plurality of fourth field strength values of the mobile terminal 7 in the locking area of the vehicle. Specifically, the structure of the second characteristic sequence can be represented as shown in Table 7 below:

[0084] In the table, D1-D10 are 10 relative position directions of the mobile terminal and the vehicle. In this embodiment, the reference Figure 3 As shown in the figure, the 10 relative position directions are ①-⑩ in the figure.

[0085] In the table, Q41-Q50 are the Bluetooth field strength values of the mobile terminal that can be detected by the vehicle when the mobile terminal is placed in the 10 relative position directions in the unlocking area of the vehicle; and Q51-Q60 are the Bluetooth field strength values of the mobile terminal that can be detected by the vehicle when the mobile terminal is placed in the 10 relative position directions in the locking area of the vehicle.

[0086] S22: Screen the second characteristic parameter sequences that meet the consistency index, construct a second characteristic parameter set, and match a calibration data packet corresponding to each second characteristic parameter set.

[0087] Specifically, the judgment standard of the consistency index is that the plurality of third field strength values and the plurality of fourth field strength values of different mobile terminals 7 in the unlocking area and the locking area of the vehicle have more than half of the values consistent.

[0088] For example:

[0089] The example values of the second characteristic parameter sequence of the first mobile terminal can be represented as shown in Table 8 below:

[0090] Table 8 Example values of the second characteristic parameter sequence of the first mobile terminal

[0091] Direction D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 Car unlock zone 65 65 65 67 66 65 63 65 64 66 Car lock zone 81 81 81 83 85 81 81 81 82 83

[0095] If more than half of the values ​​in the second feature parameter sequence of the first mobile terminal are the same as those in the second feature parameter sequence of the second mobile terminal, it is determined that the two meet the consistency index, and the Bluetooth field strength values ​​of the first mobile terminal and the second mobile terminal are combined into a second feature parameter set.

[0096] In some implementations, the step of constructing the calibration feature database 8 further includes:

[0097] S23: Obtain the model number of different mobile terminals 7;

[0098] S24: Based on the second feature parameter sequence of each mobile terminal 7, construct a set of mobile terminal models corresponding to the second feature parameter set.

[0099] The above method will be explained in detail below with reference to specific accompanying figures and application scenarios:

[0100] In one application scenario, the test vehicle is set up with the following around it: Figure 2 The diagram shows the car unlocking and locking zones, which are set based on the existing unlocking and locking distances between physical keys and cars, and market research. The inner dotted area (a) is the car unlocking zone, meaning that the car unlocks when the mobile terminal 7 is within it, and the unlocking zone is 3-5 meters from the car. The outer dotted area (b) is the car locking zone, meaning that the car locks when the mobile terminal 7 is within it, and the locking zone is 8-10 meters from the car. The area (c) between areas a and b is the car buffer zone, meaning a buffer between the mobile terminal 7 unlocking and locking the car, and the buffer zone is 5-8 meters from the car.

[0101] Reference Figure 3 For example, when constructing the calibration feature database 8, 70-80 mobile terminal models from different brands currently on the market are collected; each mobile terminal 7 is located in the car unlocking area and car locking area of ​​the test vehicle, as shown in the image. Figure 3 Measurements are taken in the indicated direction, and different mobile terminals 7 measure the corresponding second feature parameter sequences. Based on the measured second feature parameter sequences, second feature parameter sequences that meet the consistency index are selected. The Bluetooth field strength values ​​of these second feature parameter sequences are set into a range of Bluetooth field strength values ​​to construct a second feature parameter set. The corresponding calibration data packets are matched according to the constructed second feature parameter set.

[0102] After the calibration feature database 8 is built, the 70-80 mobile terminal models used for measurement are matched with the second feature parameter set and stored in the calibration feature database 8 according to the second feature parameter sequence of each mobile terminal 7. In use, the calibration feature database 8 sends the calibration data packet of the corresponding mobile terminal model to the mobile terminal 7 and the vehicle terminal respectively, and the mobile terminal 7 can use the Bluetooth non-inductive unlocking function.

[0103] In some embodiments, the mobile terminal model is not included in the calibration feature database 8. At this time, the mobile terminal 7 measures the first feature parameter set in the directions as shown in the vehicle unlocking area and the vehicle locking area of the test vehicle respectively, traverses the calibration feature database 8, selects the calibration data packet corresponding to the second feature parameter set when the first feature parameter set is similar to any second feature parameter set, and sends the calibration data packet to the mobile terminal 7. The mobile terminal 7 can use the Bluetooth non-inductive unlocking function. At the same time, the mobile terminal model is matched with the second feature parameter set and stored in the calibration feature database 8. Next time this mobile terminal model is used, it does not need to be measured again. Figure 3

[0104] In some embodiments, the directions for measuring the field strength value of the mobile terminal are the front of the main driver, the 45-degree direction of the main driver, the 90-degree direction of the main driver, the 135-degree direction of the main driver, the back of the main driver, the front of the co-driver, the 45-degree direction of the co-driver, the 90-degree direction of the co-driver, the 135-degree direction of the co-driver, and the back of the co-driver.

[0105] Specifically, the 10 directions are as shown in Figure 3 In the figure, ① is the front of the main driver, ② is the 45-degree direction of the main driver, ③ is the 90-degree direction of the main driver, ④ is the 135-degree direction of the main driver, ⑤ is the back of the main driver, ⑥ is the front of the co-driver, ⑦ is the 45-degree direction of the co-driver, ⑧ is the 90-degree direction of the co-driver, ⑨ is the 135-degree direction of the co-driver, and ⑩ is the back of the co-driver.

[0106] In some embodiments, the standard for determining that the first feature parameter set is similar to any second feature parameter set is that the first feature parameter set has the highest value coincidence degree with any second feature parameter set.

[0107] In some embodiments, the consistency index is that more than half of the values of the plurality of third field strength values and the plurality of fourth field strength values of different mobile terminals in the vehicle unlocking area and the vehicle locking area are consistent.
