[0016] If the distance between the belonging control area at the current time and the vehicle is farther than the distance between the belonging control area at the next time and the vehicle, it is determined to unlock the vehicle.

[0043] The present application provides a control method of a vehicle, a control device of a vehicle and a vehicle. The control method of a vehicle, the control device of a vehicle and the vehicle of the present application will be described in detail below with reference to the accompanying drawings. The features in the embodiments and the implementation manners described below can be combined with each other in the case of no conflict.

[0044] Figure 1 Fig. 1 shows a structure block diagram of one embodiment of the vehicle 10 of the present application. As shown in Fig. 1, the vehicle 10 comprises an antenna 11 and a control device 12 of a vehicle provided by the present application. Figure 1

[0045] The antenna 11 is used to receive the current RSSI value returned by the key 20 for the search signal. The RSSI (Received Signal Strength Indication) value is used to reflect the field strength information of the signal. The antenna 11 is also used to send the search signal. The search signal is a low frequency signal. In some embodiments, the search signal is a 125 kHz or 134 kHz low frequency signal. After the key 20 receives the search signal, it is woken up and generates a high frequency signal containing the current RSSI value. In some embodiments, the high frequency signal is a 343 MHz signal. The antenna 11 receives the high frequency signal. The antenna 11 used for sending signals and the antenna 11 used for receiving signals are different antennas.

[0046] The vehicle 10 can comprise a plurality of antennas 11 for receiving the current RSSI value returned by the key 20 for the search signal, which are respectively arranged at different positions of the vehicle 10.

[0047] ​The control device 12 of the vehicle is electrically connected with the antenna 11, and is configured to control the antenna 11. The control device 12 comprises a central electronic module (CEM). The control device 12 is configured to control the antenna 11 to send signals, and to receive and process signals received by the antenna 11. The vehicle 10 further comprises a radio frequency receiver (RFR) 13. The radio frequency receiver 13 is connected with the antenna 11, receives signals of the antenna 11, and sends the signals to the control device 12. The control device 12 decrypts and checks the signals, and determines the position of the key 20.

[0048] Figure 2 Fig. 1 shows a flow chart of one embodiment of the control method 30 of the vehicle according to the present application.

[0049] The control method 30 of the vehicle comprises steps 31-34.

[0050] In step 31, when searching for the key, it is detected in real time whether a current RSSI value returned by the key 20 for the search signal is received at the current time.

[0051] The vehicle 10 continuously sends the search signal. The control device 12 continuously controls the antenna 11 to send the search signal. The control device 12 detects in real time whether the antenna 11 receives the current RSSI value returned by the key 20 for the search signal.

[0052] In step 32, in the case that the current RSSI value is received at the current time, it is determined according to the current RSSI value whether the current RSSI value belongs to a received signal strength set of a predetermined control area. The received signal strength set comprises a calibrated value of the received signal strength which is calibrated according to a distance from the vehicle to the key.

[0053] Figure 3 Fig. 2 shows a schematic diagram of one embodiment of the predetermined control area of the vehicle 10 according to the present application.

[0054] In Figure 3 In the embodiment shown, the area A, the area B, and the area C are different predetermined control areas. The different predetermined control areas have different distances from the vehicle 10. The area C is located on the left and right sides of the vehicle 10, and does not include the front and rear areas of the vehicle 10. The area B is outside the area C, and the area B is an oval shape. Different positions have different distances from the vehicle 10. The area A is outside the area B, and the area A is an oval shape. Outside the area A, there is an area in which the vehicle 10 cannot receive signals of the key 20. In other embodiments, other predetermined control areas can be provided.

[0055] Different predetermined control zones correspond to different sets of received signal strengths. For example, when the key is located in zone A, zone B, zone C, the current RSSI value received by the antenna 11 is different. The set of received signal strengths includes a list of received signal strengths. The set of received signal strengths also includes an interval range of received signal strengths.

[0056] In the case of receiving the current RSSI value at the current time, it is compared whether the current RSSI value belongs to the set of received signal strengths of the predetermined control zone. In some embodiments, it is compared whether the current RSSI value is the same as the calibrated value of the received signal strength included in the set of received signal strengths. In other embodiments, it is compared whether the current RSSI value is within the range of the calibrated value of the received signal strength included in the set of received signal strengths.

[0057] Step 33, if the set of received signal strengths of the predetermined control zone is determined, the predetermined control zone to which the key 20 belongs is determined as the belonging control zone at the current time.

[0058] For example, zone A, zone B, zone C correspond to different sets of received signal strengths. If it is determined that the current RSSI value belongs to the set of received signal strengths of zone A, zone A is determined as the belonging control zone at the current time.

[0059] Step 34, based on the belonging control zone at the current time, it is determined whether to unlock or lock the vehicle by comparing the current RSSI value with the reception condition of the adjacent time of the current RSSI value.

[0060] The adjacent time includes the previous time and the next time of the current time. By comparing the current RSSI value with the reception condition of the adjacent time of the current RSSI value, the change of the current RSSI value can be determined, and then the change of the distance between the key 20 and the vehicle 10 can be determined, and the unlocking or locking of the vehicle is controlled according to the jump of the distance between the key 20 and the vehicle 10.

[0061] In some embodiments, the calibrated value of the received signal strength is used to calibrate the distance between the key 20 and the vehicle 10, and the set of received signal strengths includes: the calibrated value of the received signal strength which is away from the vehicle 10 outwardly from near to far with the vehicle 10 as the center. By determining whether the current RSSI value of the key 20 belongs to the set of received signal strengths of the predetermined control zone, the distance between the key 20 and the vehicle 10 can be quickly determined. In the case of receiving the current RSSI value, it is determined whether to unlock or lock the vehicle by comparing the current RSSI value with the reception condition of the adjacent time of the current RSSI value, that is, the unlocking and locking control of the vehicle 10 is started from the reception of the RSSI value of the key, and the sensitivity of the unlocking and locking control of the vehicle 10 is improved.

[0062] Optionally, the step 34 comprises: based on the control area to which the current moment belongs, in the case that the current RSSI value is not received at the current moment and the next RSSI value is received at the next moment, determining to unlock the vehicle 10.

[0063] The fact that the current RSSI value is not received at the current moment indicates that the key 20 is far away from the vehicle 10 at the current moment and the key 20 does not enter the range in which the vehicle 10 can detect the signal. The fact that the next RSSI value is received at the next moment indicates that the key 20 enters the range in which the vehicle 10 can detect the signal and the key 20 is closer to the vehicle 10 than at the current moment. The vehicle 10 is controlled to be unlocked. In this way, the vehicle 10 is unlocked when the vehicle 10 can just detect the key 20, which can prolong the unlocking distance and prevent the user from being close to the vehicle 10 while the vehicle 10 is not unlocked, thereby improving the user experience.

[0064] Optionally, the step 34 comprises: in the case that the current RSSI value is received at the current moment and the next RSSI value is received at the next moment, comparing the control area to which the current moment belongs with the control area to which the next moment belongs.

[0065] If the control area to which the current moment belongs is farther away from the vehicle 10 than the control area to which the next moment belongs, it is determined to unlock the vehicle 10.

[0066] If the control area to which the current moment belongs is farther away from the vehicle 10 than the control area to which the next moment belongs, for example, the control area to which the current moment belongs is area A and the control area to which the next moment belongs is area C, it indicates that the key 20 is approaching the vehicle 10 from the current moment to the next moment. It is determined to unlock the vehicle 10. In this way, when the vehicle 10 is locked and the user is close to the vehicle 10, the vehicle 10 can be unlocked in time, for example, after the vehicle 10 is locked, the user comes to area A and then returns to area C. At this time, the vehicle 10 can be unlocked in time, which reduces the waiting time of the user and improves the user experience.

[0067] Optionally, the step 34 comprises: based on the control area to which the current moment belongs, in the case that the current RSSI value is received at the current moment and the next RSSI value is not received at the next moment, determining to lock the vehicle 10.

[0068] The current RSSI value is received at the current moment, which indicates that the key 20 is relatively close to the vehicle 10 at the current moment, and the key 20 is in the range in which the vehicle 10 can detect the signal. The next RSSI value is not received at the next moment, which indicates that the key 20 leaves the range in which the vehicle 10 can detect the signal, and the key 20 is farther away from the vehicle 10 than at the current moment. The vehicle 10 is controlled to be locked, so that the vehicle 10 is locked when the vehicle 10 can just not detect the key 20, the locking distance can be shortened, and the user experience is improved.

[0069] Optionally, the step 34 comprises: determining to lock the vehicle 10 based on the control area to which the current moment belongs, the current RSSI value being received at the current moment, and the next RSSI value not being received at the next moment for a preset time length.

[0070] The current RSSI value is received at the current moment, the next RSSI value is not received at the next moment, and the next RSSI value is not received within the preset time length, and the vehicle 10 is controlled to be locked. In this way, the vehicle 10 is controlled to be locked when the key 20 has left the signal detection range of the vehicle 10 for a preset time length, and the vehicle 10 is less frequently unlocked and locked.

[0071] Optionally, the step 34 comprises: comparing the control area to which the current moment belongs with the control area to which the next moment belongs corresponding to the next RSSI value when the current RSSI value is received at the current moment and the next RSSI value is received at the next moment; and determining to lock the vehicle 10 when the control area to which the current moment belongs is closer to the vehicle 10 than the control area to which the next moment belongs.

[0072] When the control area to which the current moment belongs is closer to the vehicle 10 than the control area to which the next moment belongs, for example, the control area to which the current moment belongs is region C, and the control area to which the next moment belongs is region A, it is determined that the key 20 is moving away from the vehicle 10 from the current moment to the next moment, and the vehicle 10 is determined to be locked. In this way, when the user is close to the vehicle 10 and moves away from the vehicle 10 after the vehicle 10 is unlocked, the vehicle 10 can be locked in time, for example, the user comes to region C after the vehicle 10 is unlocked, and then moves back to region A, and the vehicle 10 can be locked in time, the user waiting time is reduced, and the user experience is improved.

[0073] In some embodiments, the shape of the predetermined control area matches the outer contour of the vehicle 10; and the vehicle 10 comprises at least four antennas 11 for receiving the current RSSI value returned by the key 20 for the search signal, and the four antennas 11 are arranged on the front side, the rear side, the left side and the right side of the vehicle 10, respectively. In some embodiments, the four antennas 11 are arranged on four opposite corners of the vehicle 10.

[0074] The shape of the predetermined control area matches the outer contour of the vehicle 10, for example, the shape of the predetermined control area can be the same as the outer contour of the vehicle 10, or the shape of the predetermined control area can be rectangular. When the key 20 is located in the predetermined control area, the distance between the different positions of the antenna 11 of the vehicle 10 and the key 20 is different, and the received current RSSI value is different. By comprehensively analyzing the current RSSI values received by the four antennas 11 arranged around the front, rear and sides of the vehicle 10, the predetermined control area matching the outer contour of the vehicle 10 where the key 20 is located can be accurately determined, so that the distance between the key 20 and the vehicle 10 can be accurately determined.

[0075] In some embodiments, the vehicle 10 only includes one antenna 11 for receiving the current RSSI value returned by the key 20 for the search signal, and the antenna 11 is arranged at the center of the vehicle 10, and the predetermined control area is arranged outward from the center of the vehicle 10 in sequence from near to far with the antenna 11 as the center and a predetermined value as the radius.

[0076] When the predetermined control area is arranged outward from the center of the vehicle 10 in sequence from near to far with the antenna 11 as the center and a predetermined value as the radius, when the key 20 is located in different predetermined control areas, the current RSSI value received by the antenna 11 arranged at the center of the vehicle 10 is different. By receiving the current RSSI value by the antenna 11 arranged at the center of the vehicle 10, the predetermined control area where the key 20 is located can be simply and conveniently determined, so that the distance between the key 20 and the vehicle 10 can be simply and conveniently determined.

[0077] Figure 4 The figure shows a schematic diagram of one embodiment of the application for collecting the calibration value of the received signal strength.

[0078] The calibration values of the received signal strength are uniformly distributed in the predetermined control area, and the distance between the positions of the adjacent two calibration values of the received signal strength in the same predetermined control area is the same.

[0079] In Figure 4 In the embodiment shown, three predetermined control areas are divided outward from the center of the vehicle 10 in sequence from near to far, which are the first predetermined control area, the second predetermined control area and the third predetermined control area. For each predetermined control area, 38 positions for collecting the calibration value of the received signal strength are arranged (as shown by the labels L1-L38 in the figure). The distance between the positions of the adjacent two calibration values of the received signal strength in the same predetermined control area is the same, which can be adjusted according to different vehicle models. In Figure 4 In the embodiment shown, the distance between the positions of the adjacent two calibration values of the received signal strength in the same predetermined control area is 20cm-50cm.

[0080] Taking a vehicle with four antennas installed around its front, rear, left, and right as an example, the four antennas are antenna 3, antenna 4, antenna 5, and antenna 6. Table 1 is a record of the calibrated values ​​of the collected and received signal strength.

[0081] Table 1

[0082]

[0083] When key 20 is in positions 1-38 of each predetermined control zone, the current RSSI values ​​received by antennas 3, 4, 5, and 6 are recorded, which are the calibrated values ​​of the received signal strength. In this way, the set of current RSSI values ​​received by antennas 3, 4, 5, and 6 in each predetermined control zone can be determined, which is the set of received signal strengths.

[0084] When collecting the calibration value of the received signal strength, the location of the calibration value of the received signal strength is evenly distributed within the predetermined control area. Therefore, for any key 20 in the predetermined control area, it is convenient to compare whether the current RSSI value of the key 20 matches the calibration value of the received signal strength, thereby improving the accuracy of the comparison.

In some embodiments, the vehicle control device 12 may include memory 43 and an interface 44. In some embodiments, the vehicle control device 12 may also include other hardware depending on the actual application.

[0088] The computer-readable storage medium 42 of this application embodiment stores a program that, when executed by the processor 41, is used to implement the vehicle control method 30 described above.
