Description

Technical Field

[0001] The present application relates to the technical field of vehicle remote control, and in particular to a vehicle control method, a control device, and a vehicle. Background Art

[0002] With the development of intelligent vehicles, remote vehicle control is becoming increasingly popular. Currently, many vehicles have automatic unlocking and locking functions. When the user approaches the vehicle with the key, the vehicle automatically unlocks, and when the user moves away from the vehicle with the key, the vehicle automatically locks.

[0003] However, the sensitivity of the vehicle's automatic unlocking and locking functions needs to be improved. For example, when a user approaches the vehicle quickly in rainy or snowy weather, the vehicle often fails to unlock in time, requiring the user to wait for a while before the vehicle unlocks. Furthermore, when a user moves away quickly, the vehicle often doesn't lock until the user is already quite far away, resulting in a poor user experience. Summary of the Invention

[0004] The present application provides a control method, a control device, and a vehicle with high sensitivity.

[0005] The present application provides a vehicle control method, the vehicle control method comprising: When searching for a key, detecting in real time whether a current RSSI value returned by the key in response to a search signal is received at the current moment; When a current RSSI value is received at a current moment, determining whether the current RSSI value belongs to a set of received signal strengths of a predetermined control area based on the current RSSI value; the set of received signal strengths includes: calibrated values ​​of received signal strengths extending outward from the vehicle from near to far, with the vehicle as the center; the calibrated values ​​of received signal strengths are used to calibrate the distance between the key and the vehicle; If it belongs to the set of received signal strengths of a predetermined control area, the predetermined control area to which the key belongs is determined as the control area to which the key belongs at the current moment; Based on the control zone to which the current moment belongs, a current RSSI value is compared with reception conditions of the current RSSI value at adjacent moments to determine whether to unlock or lock the vehicle.

[0006] In some embodiments, the calibration value of the received signal strength is used to calibrate the distance between the key and the vehicle. The received signal strength set includes: the calibration value of the received signal strength centered on the vehicle and expanding outward from near to far away from the vehicle. By determining whether the current RSSI value of the key belongs to the received signal strength set of a predetermined control area, the control area to which it belongs at the current moment is determined, and the distance between the key and the vehicle can be quickly determined. When the current RSSI value is received, the current RSSI value is compared with the reception status of adjacent RSSI values ​​to determine whether to unlock or lock the vehicle. That is, the vehicle is unlocked and locked starting from the receipt of the key's RSSI value, thereby improving the sensitivity of the vehicle unlocking and locking control.

[0007] Optionally, the determining whether to unlock or lock the vehicle by comparing a current RSSI value with reception conditions at adjacent times of the current RSSI value based on the control zone to which the current moment belongs includes: Based on the control zone to which the vehicle belongs at the current moment, if the current RSSI value is not received at the current moment and the next RSSI value is received at the next moment, it is determined to unlock the vehicle.

[0008] In some embodiments, when the current RSSI value is not received at the current moment and the next RSSI value is received at the next moment, the vehicle is determined to be unlocked. When the current RSSI value is not received, it means that the key is far away from the vehicle. When the next RSSI value is received, it means that the key is close to the vehicle. Controlling the unlocking of the vehicle can extend the unlocking distance to prevent the user from being close to the vehicle before the vehicle is unlocked, and the user experience is high.

[0009] Optionally, the determining whether to unlock or lock the vehicle by comparing a current RSSI value with reception conditions at adjacent times of the current RSSI value based on the control zone to which the current moment belongs includes: When a current RSSI value is received at a current moment and a next RSSI value is received at a next moment, comparing the control area at the current moment with the control area at the next moment corresponding to the next RSSI value; If the control zone at the current moment is farther away from the vehicle than the control zone at the next moment, it is determined to unlock the vehicle.

[0010] In some embodiments, if the control area at the current moment is farther away from the vehicle than the control area at the next moment, it means that the key is approaching the vehicle, and the vehicle is unlocked. In this way, when the vehicle is locked, the user can unlock the vehicle in time when he is close to the vehicle and approaches the vehicle, thereby improving the user experience.

[0011] Optionally, the determining whether to unlock or lock the vehicle by comparing a current RSSI value with reception conditions at adjacent times of the current RSSI value based on the control zone to which the current moment belongs includes: Based on the control area to which the vehicle belongs at the current moment, when a current RSSI value is received at the current moment and a next RSSI value is not received at the next moment, it is determined to lock the vehicle.

[0012] In some embodiments, when the current RSSI value is received at the current moment and the next RSSI value is not received at the next moment, the vehicle is determined to be locked. When the current RSSI value is received, it means that the key is close to the vehicle. When the next RSSI value is not received, it means that the key is far away from the vehicle. Controlling the vehicle locking can shorten the locking distance and prevent the user from being far away from the vehicle before the vehicle is locked, thereby improving the user experience.

[0013] Optionally, the determining whether to unlock or lock the vehicle by comparing a current RSSI value with reception conditions at adjacent times of the current RSSI value based on the control zone to which the current moment belongs includes: When a current RSSI value is received at a current moment and a next RSSI value is received at a next moment, comparing the control area at the current moment with the control area at the next moment corresponding to the next RSSI value; If the control zone at the current moment is closer to the vehicle than the control zone at the next moment, it is determined to lock the vehicle.

[0014] In some embodiments, if the control area at the current moment is closer to the vehicle than the control area at the next moment, it means that the key is moving away from the vehicle, and the vehicle is locked. In this way, when the vehicle is unlocked, the user can lock the vehicle in time when he is close to the vehicle and away from the vehicle at the same time, thereby improving the user experience.

[0015] Optionally, the shape of the predetermined control area matches the outer contour of the vehicle; the vehicle includes at least four antennas for receiving the current RSSI value returned by the key for the search signal, and the four antennas are respectively arranged on the front, rear, left and right sides of the vehicle.

[0016] In some embodiments, the current RSSI values ​​received by four antennas respectively arranged at the front, rear, left and right sides of the vehicle can accurately determine the predetermined control area where the key is located that matches the outer contour of the vehicle, thereby accurately determining the distance between the key and the vehicle.

[0017] Optionally, the vehicle includes an antenna for receiving the current RSSI value returned by the key for the search signal, the antenna is arranged at the center of the vehicle, and the predetermined control area is arranged in sequence from near to far away from the vehicle with the antenna as the center and the predetermined value as the radius.

[0018] In some embodiments, the current RSSI value received by the antenna set at the center of the vehicle can simply and conveniently determine the predetermined control area where the key is located with the antenna as the center and a predetermined value as the radius, thereby simply and conveniently determining the distance between the key and the vehicle.

[0019] Optionally, the calibration values ​​of the received signal strength are evenly distributed in the predetermined control area, and the distances between the positions of two adjacent calibration values ​​of the received signal strength in the same predetermined control area are the same.

[0020] In some embodiments, the calibration value of the received signal strength is evenly distributed within the predetermined control area, so that for a key at any position within the predetermined control area, it is convenient to compare whether the current RSSI value of the key matches the calibration value of the received signal strength, thereby improving the comparison accuracy.

[0021] The present application provides a vehicle control device, comprising one or more processors, for implementing the vehicle control method as described in any one of the above items.

[0022] The present application provides a vehicle, comprising: an antenna for receiving a current RSSI value returned by the key in response to the search signal; and The vehicle control device as described above is electrically connected to the antenna and is used to control the antenna.

[0023] The present application provides a computer-readable storage medium having a program stored thereon. When the program is executed by a processor, the vehicle control method as described in any one of the above items is implemented.

[0024] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present application provides a vehicle control method, a control device, and a vehicle. The vehicle control method, the control device, and the vehicle of the present application are described in detail below with reference to the accompanying drawings. The features of the following embodiments and implementations may be combined with each other unless they conflict.

[0032] Figure 1 FIG. 1 is a block diagram of a vehicle 10 according to an embodiment of the present invention. Figure 1 As shown, the vehicle 10 includes: an antenna 11 and a vehicle control device 12 provided in this application.

[0033] Antenna 11 is used to receive the current RSSI value returned by key 20 in response to the search signal. The RSSI (Received Signal Strength Indication) value is used to reflect the signal's field strength information. 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 125kHz or 134kHz low-frequency signal. After receiving the search signal, key 20 is awakened and generates a high-frequency signal containing the current RSSI value. In some embodiments, the high-frequency signal is a 343MHz signal. Antenna 11 receives this high-frequency signal. The antenna 11 used for sending signals and for receiving signals is different.

[0034] The vehicle 10 may include a plurality of antennas 11 for receiving the current RSSI value returned by the key 20 in response to the search signal, respectively disposed at different locations of the vehicle 10 .

[0035] The vehicle's control device 12 is electrically connected to the antenna 11 and is used to control the antenna 11. The control device 12 includes a central electronic module (CEM). The control device 12 is used to control the antenna 11 in transmitting signals and to receive and process signals received by the antenna 11. The vehicle 10 also includes a radio frequency receiver (RFR) 13. The RF receiver 13 is connected to the antenna 11, receives signals from the antenna 11, and transmits them to the control device 12. The control device 12 decrypts and verifies the signals to determine the location of the key 20.

[0036] Figure 2 FIG. 1 is a flow chart of an embodiment of a vehicle control method 30 of the present application.

[0037] The vehicle control method 30 includes steps 31 to 34 .

[0038] Step 31 : When searching for the key, whether the current RSSI value returned by the key 20 in response to the search signal is received at the current moment is detected in real time.

[0039] The vehicle 10 continuously transmits the search signal. The control device 12 continuously controls the antenna 11 to transmit 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 in response to the search signal.

[0040] In step 32, upon receiving the current RSSI value at the current moment, a determination is made based on the current RSSI value whether the current RSSI value belongs to a set of received signal strengths for a predetermined control area. The set of received signal strengths includes calibrated values ​​of received signal strengths extending outward from the vehicle, starting from near and moving away from the vehicle. The calibrated received signal strength values ​​are used to calibrate the distance between the key and the vehicle.

[0041] Figure 3 Shown is a schematic diagram of an embodiment of a predetermined control zone of the vehicle 10 of the present application.

[0042] exist Figure 3 In the illustrated embodiment, Area A, Area B, and Area C are different predetermined control zones. Each predetermined control zone is located at a different distance from the vehicle 10. Area C is located on the left and right sides of the vehicle 10 and does not include the areas in front of or behind the vehicle 10. Area B is outside Area C and is elliptical in shape, with different distances from the vehicle 10 at different locations. Area A is outside Area B and is elliptical in shape. Areas outside Area A are areas where the vehicle 10 cannot receive signals from the key fob 20. In other embodiments, other predetermined control zones may be defined.

[0043] Different predetermined control zones correspond to different received signal strength sets. For example, when the key is located in zone A, zone B, and zone C, the current RSSI values ​​received by antenna 11 are different. The received signal strength set includes a received signal strength list. The received signal strength set also includes a range of received signal strengths.

[0044] When a current RSSI value is received at the current moment, the current RSSI value is compared to see if it belongs to a set of received signal strength values ​​for a predetermined control area. In some embodiments, the current RSSI value is compared to see if it is the same as a calibrated received signal strength value included in the set of received signal strength values. In other embodiments, the current RSSI value is compared to see if it is within a range of calibrated received signal strength values ​​included in the set of received signal strength values.

[0045] Step 33: If the received signal strength set belongs to a predetermined control area, the predetermined control area to which the key 20 belongs is determined as the control area to which the key 20 belongs at the current moment.

[0046] For example, different received signal strength sets correspond to regions A, B, and C. If it is determined that the current RSSI value belongs to the received signal strength set of region A, region A is taken as the control area at the current moment.

[0047] Step 34 : Based on the control zone to which the current moment belongs, the current RSSI value is compared with the reception status of the current RSSI value at adjacent moments to determine whether to unlock or lock the vehicle.

[0048] Adjacent moments include the previous and next moments of the current moment. By comparing the current RSSI value with the current RSSI value at adjacent moments, the change in the current RSSI value can be determined, and thus the change in the distance between the key 20 and the vehicle 10 can be determined. Based on the jump in the distance between the key 20 and the vehicle 10, the vehicle can be unlocked or locked.

[0049] In some embodiments, the calibration value of the received signal strength is used to calibrate the distance between the key 20 and the vehicle 10. The received signal strength set includes: the calibration value of the received signal strength expanding outward from near to far away from the vehicle 10 with the vehicle 10 as the center. By determining whether the current RSSI value of the key 20 belongs to the received signal strength set of a predetermined control area, the control area to which it belongs at the current moment is determined, and the distance between the key 20 and the vehicle 10 can be quickly determined. When the current RSSI value is received, the current RSSI value is compared with the reception status of the current RSSI value at adjacent moments to determine whether to unlock or lock the vehicle. That is, the vehicle 10 is unlocked and locked starting from the receipt of the key's RSSI value, thereby improving the sensitivity of the unlocking and locking control of the vehicle 10.

[0050] Optionally, step 34 includes: based on the control zone at the current moment, if 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 .

[0051] If the current RSSI value is not received at the current moment, it means that the key 20 is far away from the vehicle 10 at the current moment and the key 20 is not within the range where the vehicle 10 can detect the signal. If the next RSSI value is received at the next moment, it means that the key 20 has entered the range where the vehicle 10 can detect the signal. Compared with the current moment, the key 20 is closer to the vehicle 10, and the vehicle 10 is controlled to unlock. In this way, the vehicle 10 is unlocked as soon as the vehicle 10 can just detect the key 20, which can extend the unlocking distance and prevent the user from getting close to the vehicle 10 when the vehicle 10 is not unlocked, thereby improving the user experience.

[0052] Optionally, step 34 includes: when a current RSSI value is received at a current moment and a next RSSI value is received at a next moment, comparing the control area at the current moment with the control area at the next moment corresponding to the next RSSI value; If the control zone at the current moment is farther away from the vehicle 10 than the control zone at the next moment, it is determined that the vehicle 10 is unlocked.

[0053] If the control area at the current moment is farther away from the vehicle 10 than the control area at the next moment, for example, the control area at the current moment is area A, and the control area at the next moment is area C, it means that from the current moment to the next moment, the key 20 is approaching the vehicle 10, and the vehicle 10 is determined to be unlocked. In this way, after the vehicle 10 is locked, the user can unlock the vehicle 10 in time when he is close to the vehicle 10 and is close to the vehicle 10. For example, after the vehicle 10 is locked, the user moves away from the vehicle 10 to area A, and then returns to area C. At this time, the vehicle 10 can be unlocked in time, reducing the user waiting time and improving the user experience.

[0054] Optionally, step 34 includes: based on the control area to which the current moment belongs, when a current RSSI value is received at the current moment and a next RSSI value is not received at the next moment, determining to lock the vehicle 10 .

[0055] Receiving the current RSSI value at the current moment indicates that the key 20 is relatively close to the vehicle 10 at the current moment and is within the range where the vehicle 10 can detect the signal. If the next RSSI value is not received at the next moment, it indicates that the key 20 has left the range where the vehicle 10 can detect the signal and is further away from the vehicle 10 than at the current moment. The vehicle 10 is locked. In this way, locking the vehicle 10 just as the vehicle 10 stops detecting the key 20 can shorten the locking distance and prevent the vehicle 10 from locking even when the user is far away from it, thus improving the user experience.

[0056] Optionally, step 34 includes: based on the control area to which the current moment belongs, determining to lock the vehicle 10 when a current RSSI value is received at the current moment and a next RSSI value is not received at the next moment for a preset time period.

[0057] If the current RSSI value is received at the current moment and the next RSSI value is not received at the next moment, and the next RSSI value is not received within a preset time period, the vehicle 10 is locked. In this way, the vehicle 10 is locked after the key 20 has been out of the signal detection range of the vehicle 10 for a preset time period, thereby reducing the frequent unlocking and locking of the vehicle 10.

[0058] Optionally, step 34 includes: when 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 at the current moment with the control area at the next moment corresponding to the next RSSI value; if the control area at the current moment is closer to the vehicle 10 than the control area at the next moment, determining to lock the vehicle 10.

[0059] If the control area at the current moment is closer to the vehicle 10 than the control area at the next moment, for example, the control area at the current moment is area C, and the control area at the next moment is area A, it means that from the current moment to the next moment, the key 20 is moving away from the vehicle 10, and the vehicle 10 is determined to be locked. In this way, after the vehicle 10 is unlocked, the user can lock the vehicle 10 in time when the user is close to the vehicle 10 and away from the vehicle 10 at the same time. For example, after the vehicle 10 is unlocked, the user approaches the vehicle 10 to area C and then returns to area A. At this time, the vehicle 10 can be locked in time, reducing the user's waiting time and improving the user experience.

[0060] In some embodiments, the shape of the predetermined control area matches the outer contour of the vehicle 10. The vehicle 10 includes at least four antennas 11 for receiving the current RSSI value returned by the key 20 in response to the search signal. The four antennas 11 are respectively disposed on the front, rear, left, and right sides of the vehicle 10. In some embodiments, the four antennas 11 are respectively disposed at the four diagonal corners of the vehicle 10.

[0061] The shape of the predetermined control zone matches the outer contour of vehicle 10. For example, the predetermined control zone can be identical to the outer contour of vehicle 10, or it can be rectangular. When key 20 is within the predetermined control zone, antennas 11 at different locations on vehicle 10 are at different distances from key 20, and thus receive different current RSSI values. By comprehensively analyzing the current RSSI values ​​received by the four antennas 11 located at the front, back, left, and right sides of vehicle 10, the key 20 can be accurately determined to be within the predetermined control zone that matches the outer contour of vehicle 10, thereby accurately determining the distance between key 20 and vehicle 10.

[0062] In some embodiments, the vehicle 10 includes only one antenna 11 for receiving the current RSSI value returned by the key 20 for the search signal. The antenna 11 is set at the center of the vehicle 10. The predetermined control area is centered on the antenna 11 and has a predetermined value as the radius, and is set in sequence from near to far away from the vehicle 10.

[0063] When predetermined control zones are arranged with antenna 11 as the center and a predetermined radius, moving outward from vehicle 10, the current RSSI values ​​received by antenna 11 at the center of vehicle 10 will be different when key 20 is located in different predetermined control zones. The current RSSI values ​​received by antenna 11 at the center of vehicle 10 can be used to easily and conveniently determine the predetermined control zone in which key 20 is located, thereby easily and conveniently determining the distance between key 20 and vehicle 10.

[0064] Figure 4 Shown is a schematic diagram of an embodiment of collecting calibration values ​​of received signal strength according to the present application.

[0065] The calibration values ​​of the received signal strength are evenly distributed in the predetermined control area, and the distance between the positions of two adjacent calibration values ​​of the received signal strength in the same predetermined control area is the same.

[0066] exist Figure 4 In the embodiment shown, with vehicle 10 as the center, three predetermined control zones are divided outward from near to far away from vehicle 10, namely the first predetermined control zone, the second predetermined control zone, and the third predetermined control zone. For each predetermined control zone, 38 locations for collecting calibration values ​​of received signal strength are set (as shown by labels L1-L38 in the figure). The distance between two adjacent locations of calibration values ​​of received signal strength in the same predetermined control zone is the same, and this distance can be adjusted according to different vehicle models. Figure 4 In the illustrated embodiment, the distance between two adjacent locations of the calibration values ​​of the received signal strength within the same predetermined control area is 20 cm to 50 cm.

[0067] For example, four antennas are provided at the front, rear, left, and right sides of the vehicle 10. The four antennas are antenna 3, antenna 4, antenna 5, and antenna 6. Table 1 is a record table of calibration values ​​of the collected received signal strengths.

[0068] Table 1

[0069] 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, i.e., 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 within each predetermined control zone, i.e., the set of received signal strengths, can be determined.

[0070] When collecting the calibration value of the received signal strength, the positions of the calibration value of the received signal strength are evenly distributed within the predetermined control area, so that for the key 20 at any position within 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 comparison accuracy.

[0071] Figure 5 Shown is a structural block diagram of an embodiment of the vehicle control device 12 of the present application.

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

[0074] The computer-readable storage medium 42 of the embodiment of the present application stores a program thereon, which, when executed by the processor 41 , is used to implement the vehicle control method 30 described above.
