Description

[Technical Field]

[0001] An embodiment of the present disclosure provides a method for operating an opening and closing member of a vehicle, and a vehicle. This application claims priority from Chinese patent application No. 202210337330.4 filed on March 31, 2022, and for designated states where incorporation by reference of documents is permitted, the contents of the above application are incorporated by reference into this application and made part of the description of this application. [Background technology]

[0002] In order to open or close opening / closing components such as the front door, rear door, trunk, and car windows, it is necessary to initiate an opening / closing command to the opening / closing components of the vehicle. An opening / closing command can be initiated by pressing a specific button on a vehicle key, kicking a specific part of the vehicle with a foot, or making a specific gesture. However, it can be difficult to perform such an operation when carrying heavy luggage or when both hands are occupied. Furthermore, some methods for initiating an opening / closing command to the opening / closing components of the vehicle have drawbacks, such as complex methods, high learning costs, and low reliability. Summary of the Invention [Problem to be solved by the invention]

[0003] Therefore, there is a need to provide a method for operating a vehicle opening and closing member that allows for simple operation by a user, is easy to learn, is highly reliable, and is low cost. [Means for solving the problem]

[0004] At least one embodiment of the present disclosure provides a method for operating an opening / closing member of a vehicle, the method including: determining whether a first mobile terminal is within a predetermined spatial range relative to the opening / closing member; determining by a second mobile terminal whether the second mobile terminal has remained stationary for a first predetermined period based on a signal from a sensor from the second mobile terminal; if the second mobile terminal has determined that the second mobile terminal has remained stationary for the first predetermined period, the second mobile terminal transmitting first stationary behavior information to the vehicle; and if the vehicle has received the first stationary behavior information from the second mobile terminal, switching the opening / closing member from a first state to a second state, where the first state is one of an open state and a closed state, and the second state is the other of the open state and the closed state.

[0005] For example, in some embodiments, the sensor is a motion sensor and is one selected from the group consisting of an acceleration sensor, an angular velocity sensor, and a magnetometer.

[0006] For example, in some embodiments, the method further includes the steps of: when the first mobile terminal determines that it is within a predetermined spatial range relative to the opening / closing member, the second mobile terminal determining whether the second mobile terminal has remained stationary for a second predetermined period of time that is shorter than the first predetermined period of time based on a signal from a sensor from the second mobile terminal; when the second mobile terminal determines that it has remained stationary for the second predetermined period of time, the second mobile terminal transmitting second stationary behavior information to the vehicle; and when the vehicle receives the second stationary behavior information, transmitting a warning signal indicating that the opening / closing member should be switched from the first state to the second state. By transmitting the warning signal, a user of the vehicle is notified that the door or trunk is being opened or closed.

[0007] For example, in some embodiments, the warning signal is transmitted by at least one of the vehicle, the first mobile terminal, or the second mobile terminal.

[0008] For example, in some embodiments, the method further includes stopping transmission of the warning signal and maintaining the opening / closing member in the first state if the vehicle does not receive the first stationary behavior information within a predetermined period after receiving the second stationary behavior information. If a vehicle user stays near the vehicle for a predetermined period but does not want to open the door or trunk, the user can cancel the stationary state after observing the warning signal, thereby canceling the automatic opening / closing operation of the door or trunk.

[0009] For example, in some embodiments, when the first state is an open state, the second predetermined period is a second open predetermined period, and when the first state is a closed state, the second predetermined period is a second closed predetermined period, the second open predetermined period being shorter than the second closed predetermined period.

[0010] For example, in some embodiments, when the first state is an open state, the difference between the first predetermined period and the second predetermined period is a third open predetermined period, and when the first state is a closed state, the difference between the first predetermined period and the second predetermined period is a third closed predetermined period, the third open predetermined period being shorter than the third closed predetermined period.

[0011] For example, in some embodiments, the first mobile terminal and the second mobile terminal are the same mobile terminal.

[0012] For example, in some embodiments, the first mobile terminal and the second mobile terminal are mobile phones or vehicle keys.

[0013] For example, in some embodiments, the first mobile terminal and the second mobile terminal are different mobile terminals.

[0014] For example, in some embodiments, the first mobile terminal is a vehicle key and the second mobile terminal is a mobile phone that communicates wirelessly with the vehicle.

[0015] For example, in some embodiments, the predetermined spatial range includes a spatial range at a predetermined distance from the vehicle and a spatial range inside the vehicle, so that if a vehicle key or a mobile phone is accidentally dropped inside the vehicle, the door can be automatically opened to prevent inconvenience.

[0016] For example, in some embodiments, the opening and closing member includes at least one of a front door, a rear door, a trunk, and a vehicle window.

[0017] At least one embodiment of the present disclosure provides a vehicle, the vehicle including an opening / closing member and a controller, the controller being configured to determine whether a first mobile terminal is within a predetermined spatial range relative to the opening / closing member, transmit location confirmation information to a second mobile terminal confirming that the first mobile terminal is within the predetermined spatial range relative to the opening / closing member, receive first stationary behavior information from the second mobile terminal indicating that the second mobile terminal has remained stationary for a first predetermined period of time, and switch the opening / closing member from a first state to a second state in response to the first stationary behavior information received from the second mobile terminal, wherein the first state is one of an open state and a closed state, and the second state is the other of the open state and the closed state.

[0018] For example, in some embodiments, the vehicle further includes a vehicle-side warning device, and the controller is further configured to receive second stationary behavior information from the second mobile terminal indicating that the second mobile terminal remains stationary for a second predetermined period shorter than the first predetermined period, and to cause the vehicle-side warning device to transmit a warning signal indicating switching the opening / closing member from the first state to the second state in response to the second stationary behavior information received from the second mobile terminal.

[0019] For example, in some embodiments, the predetermined spatial range includes a spatial range at a predetermined distance from the vehicle and a spatial range inside the vehicle.

[0020] For example, in some embodiments, the first mobile terminal and the second mobile terminal are any one selected from a vehicle key and a mobile phone.

[0021] For example, in some embodiments, the opening and closing member includes at least one of a front door, a rear door, a trunk, and a vehicle window. [Effects of the Invention]

[0022] According to the present invention, the vehicle determines whether it is necessary to open the doors, trunk, etc. based on the detection of the user's stationary state by the vehicle key or mobile phone held by the user, without requiring any action or posture by the user, particularly when both hands are occupied, thereby facilitating use of the vehicle.

[0023] In addition, by detecting the user's status using a sensor built into a mobile terminal carried by the user, such as a mobile phone or a vehicle key, the user's information can be grasped more accurately and timely and transmitted to the vehicle, which reduces costs and improves detection speed and accuracy compared to the polling method via the vehicle.

[0028] FIG. 1 is a schematic diagram of a vehicle system according to an embodiment of the present disclosure.

[0029] As shown in FIG. 1, the vehicle system includes a vehicle 110 and a mobile terminal 120 .

[0030] The vehicle 110 includes an opening / closing member 112, a vehicle-side communication unit 113, a vehicle-side warning device 114, and a vehicle-side controller 111. The opening / closing member 112 may include at least one of a pair of front doors, a pair of rear doors, a plurality of vehicle windows, a trunk, etc., but the present invention is not limited thereto. The vehicle-side communication unit 113 is configured to interact with a mobile terminal and may include at least one of a low-frequency communication antenna, a Bluetooth® antenna, a UWB (ultra-wideband) communication antenna, a UHF (ultra-high frequency) communication antenna, a 2G / 3G / 4G / 5G mobile communication antenna, and a Wi-Fi antenna, etc. The vehicle-side warning device 114 is configured to transmit a warning signal to a user and may include, for example, vehicle lights, a horn, and a speaker. The vehicle lights can transmit a warning signal to a user by flashing, the horn can transmit a warning signal to a user by honking, and the speaker can transmit a warning signal to a user by playing a voice prompt. The vehicle-side controller 111 is communicatively connected to the opening / closing member 112, the vehicle-side communication unit 113, and the vehicle-side warning device 114, and transmits signals to these members or receives signals from these members. The vehicle-side controller 111 may be a vehicle electronic control unit or a standalone controller, and the present invention is not limited thereto.

[0031] The mobile terminal 120 includes a motion sensor 122, a mobile communication unit 123, a mobile warning device 124, and a mobile controller 121. The motion sensor 122 is configured to sense whether the mobile terminal 120 is in a stationary state, and may include, for example, at least one of an acceleration sensor, an angular velocity sensor, and a magnetometer. The acceleration sensor can detect whether the mobile terminal 120 is in a stationary state based on the acceleration level of the mobile terminal 120. Specifically, when the mobile terminal 120 is in a stationary state, the change in acceleration is usually zero, but the mobile terminal 120 experiences a certain acceleration while moving, and the acceleration value changes over time. The acceleration sensor is used to continuously obtain the acceleration value of the mobile terminal 120 at a certain frequency, and if the change in the acceleration value on each of the three axes within a certain time range is all below a predetermined threshold, it can be determined that the mobile terminal 120 is in a stationary state within that time range. The angular velocity sensor can detect whether the mobile terminal 120 is in a stationary state based on the angular velocity level of the mobile terminal 120. Specifically, when the mobile terminal 120 is in a stationary state, the change in angular velocity is usually zeroHowever, the mobile terminal 120 has a constant angular velocity while moving, and the angular velocity value changes over time. An angular velocity sensor is used to continuously acquire the angular velocity values ​​of the mobile terminal 120 at a constant frequency. If the changes in the angular velocity values ​​on each of the three axes within a certain time range are all less than a predetermined threshold, it can be determined that the mobile terminal 120 is in a stationary state within that time range. A magnetometer can detect whether the mobile terminal 120 is in a stationary state based on the magnetic field strength level of the mobile terminal 120. Specifically, when the mobile terminal 120 is in a stationary state, the change in magnetic field strength is usually zero. However, the mobile terminal 120 has a constant magnetic field strength while moving, and the magnetic field strength value changes over time. A magnetometer is used to continuously acquire the magnetic field strength values ​​of the mobile terminal 120 at a constant frequency. If the changes in the magnetic field strength values ​​on each of the three axes within a certain time range are all less than a predetermined threshold, it can be determined that the mobile terminal 120 is in a stationary state within that time range. The mobile warning device 124 is configured to transmit a warning signal to the user and may include, for example, a buzzer and a lamp for transmitting an audible warning signal and a visual warning signal, respectively. The mobile controller 121 is communicatively connected to the mobile communication unit 123, the motion sensor 122, and the mobile warning device 124, and transmits signals to or receives signals from these components. The mobile controller 121 may include a processing device such as a microprocessor and a storage device. Corresponding to the vehicle communication unit 113, the mobile communication unit 123 may include at least one of a low-frequency communication antenna, a Bluetooth® antenna, a UWB communication antenna, a UHF communication antenna, a 2G / 3G / 4G / 5G mobile communication antenna, and a Wi-Fi antenna. The vehicle 110 and the mobile terminal 120 can communicate with and authenticate each other via the vehicle communication unit 113 and the mobile communication unit 123. The vehicle-side communication unit 113 can also determine the location of the mobile terminal 120 based on communication with a mobile-side communication unit 123, such as a low-frequency communication antenna, a Bluetooth® antenna, or a UWB antenna mounted at multiple different locations on the vehicle 110.

[0032] The mobile terminal 120 may be a vehicle key, a mobile phone, a tablet computer, or any other mobile terminal that is easily portable.

[0033] 2 is a flowchart of a method for operating the opening / closing member 112 of the vehicle 110 according to one embodiment of the present disclosure. The method may be performed, for example, by the vehicle system shown in FIG. 1. In particular, the mobile terminal 120 of the vehicle system is a vehicle key. However, in other embodiments, the vehicle key may be another type of mobile terminal 120, such as a mobile phone, and the present disclosure is not limited thereto.

[0034] 2, in step S210, the vehicle 110 determines whether the mobile terminal 120 is within a predetermined spatial range relative to the opening / closing member 112. For example, the vehicle 110 can transmit a low-frequency wake-up signal to the mobile terminal 120 via a vehicle-side low-frequency communication antenna. The vehicle 110 can interact with the mobile-side low-frequency communication antenna of the mobile terminal 120 via the low-frequency wake-up signal transmitted from the multiple vehicle-side low-frequency communication antennas to confirm the location of the mobile terminal 120, i.e., whether the mobile terminal 120 is within a predetermined spatial range relative to the opening / closing member 112.

[0035] If the vehicle 110 determines that the mobile terminal 120 is within a predetermined spatial range relative to the opening / closing member 112, in step S220, the vehicle 110 transmits location confirmation information to the mobile terminal 120 indicating that the mobile terminal 120 is within the predetermined spatial range relative to the opening / closing member 112.

[0036] For example, the vehicle 110 can use a low frequency antenna to transmit location information to the mobile terminal 120. Also, for example, the vehicle 110 can transmit the location information along with vehicle-side authentication information to the mobile terminal 120 to wake up the mobile terminal 120.

[0037] If location information is received, then in step S230, the mobile terminal 120 begins to detect whether the mobile terminal 120 remains stationary for a first predetermined period of time.

[0038] For example, upon receiving confirmation information from vehicle 110, mobile terminal 120 may begin using motion sensor 122 to detect whether mobile terminal 120 remains stationary for a first predetermined period of time.

[0039] Also, for example, when the vehicle 110 transmits location confirmation information together with vehicle-side authentication information to the mobile terminal 120 to wake up the mobile terminal 120, the mobile terminal 120 receives the location confirmation information and the correct vehicle-side authentication information, authenticates with the vehicle 110, and then starts detecting stationary behavior. The mobile terminal 120 can transmit the mobile-side authentication information to the vehicle 110 via a Bluetooth (registered trademark) antenna or a UHF antenna.

[0040] If the mobile terminal 120 determines that the mobile terminal 120 has remained stationary for the first predetermined period, then in step S240, the mobile terminal 120 transmits first stationary behavior information to the vehicle 110.

[0041] For example, the mobile terminal 120 may transmit the first stationary behavior information to the vehicle 110 via a Bluetooth antenna, a UHF antenna, or the like.

[0042] When the vehicle 110 receives the first stationary behavior information from the mobile terminal 120, in step S250, the vehicle 110 switches the opening / closing member 112 between the open state and the closed state.

[0043] For example, if the opening / closing member 112 is in an open state, the vehicle 110 closes the opening / closing member 112 after receiving the first stationary behavior information. For example, if the opening / closing member 112 is in a closed state, the vehicle 110 opens the opening / closing member 112 after receiving the first stationary behavior information.

[0044] In one example, the opening / closing member 112 is a trunk, the predetermined spatial range is a spatial range within a predetermined distance from the outside of the vehicle 110 to the trunk, and the opening / closing member 112 is in a closed state. Since a user typically carries the mobile terminal 120 by putting it in a pocket of their clothes or holding it in their hand, the mobile terminal 120 remaining stationary for the first predetermined period means that the user has remained stationary for the first predetermined period. In step S250, the vehicle 110 opens the trunk after receiving the first stationary behavior information indicating that the user has remained stationary for the first predetermined period.

[0045] In one example, the opening / closing member 112 is a trunk, the predetermined spatial range is a spatial range within a predetermined distance from the outside of the vehicle 110 to the trunk, and the opening / closing member 112 is in an open state. The mobile terminal 120 remaining stationary for a first predetermined period means that the user has remained stationary for the first predetermined period. In step S250, the vehicle 110 closes the trunk after receiving first stationary behavior information indicating that the user has remained stationary for the first predetermined period.

[0046] Therefore, this method allows the user to switch the opening / closing member 112 between an open state and a closed state simply by remaining stationary within a predetermined spatial range relative to the opening / closing member 112 for a first predetermined period of time. The user can operate the opening / closing member 112 simply and easily, without requiring a high learning curve. The user can also operate the opening / closing member 112 even when carrying heavy luggage or with both hands occupied. This method also detects whether the user is stationary using a sensor in the mobile terminal 120 carried by the user. Compared to other methods for detecting whether the user is stationary, this method offers higher detection accuracy, higher sensitivity, a lower false detection rate, and lower costs. For example, it reduces the possibility of detecting that the user is stationary even though the user is moving, and of false detections that do not detect that the user is stationary. Furthermore, this method can be implemented by simply modifying the mobile terminal 120, without modifying the vehicle 110, thereby reducing hardware costs.

[0047] In one example, the opening / closing member 112 is a trunk, the predetermined spatial range is a spatial range within a predetermined distance from the interior of the vehicle 110 to the trunk, and the opening / closing member 112 is in a closed state. In such a case, the mobile terminal 120 remaining stationary for a first predetermined period of time may mean that a key has been left inside the trunk. In step S250, the vehicle 110 opens the trunk after receiving the first stationary behavior information indicating that the vehicle key has been left inside the trunk.

[0048] By limiting the predetermined spatial range to the spatial range inside the vehicle 110, the opening / closing member 112 can be automatically opened when the mobile terminal 120, such as a vehicle key, is left inside the vehicle 110. This avoids the occurrence of an awkward situation where the mobile terminal 120 is trapped inside the vehicle 110.

[0049] 2, the method further includes steps S260, S270, and S280. If the vehicle 110 determines that the mobile terminal 120 is within a predetermined spatial range relative to the opening / closing member 112, then in step S260, the vehicle 110 determines whether the mobile terminal 120 will leave the predetermined spatial range. If the vehicle 110 determines that the mobile terminal 120 will leave the predetermined spatial range, then in step S270, the vehicle 110 transmits location departure information to the mobile terminal 120. If the mobile terminal 120 receives the location departure information, then in step S280, the mobile terminal 120 stops detecting stationary behavior.

[0050] In one example, the mobile terminal 120 may start timing when it starts detecting stationary behavior after receiving location confirmation information. After a maximum predetermined detection period (e.g., 10 minutes) has elapsed since starting to detect stationary behavior, the mobile terminal 120 stops detecting stationary behavior. This avoids a situation in which the mobile terminal 120 continues detecting stationary behavior because it does not receive location departure information from the vehicle 110, thereby wasting the remaining battery power of the mobile terminal 120.

[0051] 3 is a flowchart of a method for operating the opening / closing member 112 of the vehicle 110 according to another embodiment of the present disclosure. The method may be performed, for example, by the vehicle system shown in FIG. 1. In particular, the mobile terminal 120 of the vehicle system is a key for the vehicle. For the sake of brevity, a description of steps that are the same as or similar to those in the method shown in FIG. 2 will be omitted.

[0052] As shown in FIG. 3, in step S310, the vehicle 110 determines whether the mobile terminal 120 is within a predetermined spatial range relative to the opening / closing member 112.

[0053] If the vehicle 110 determines that the mobile terminal 120 is within a predetermined spatial range relative to the opening / closing member 112, in step S320, the vehicle 110 transmits location confirmation information to the mobile terminal 120 indicating that the mobile terminal 120 is within a predetermined spatial range relative to the trunk.

[0054] If location confirmation information is received, then in step S330, the mobile terminal 120 begins to detect whether the mobile terminal 120 remains stationary for a second predetermined period of time.

[0055] If the mobile terminal 120 determines that the mobile terminal 120 remains stationary for the second predetermined period, then in step S340, the mobile terminal 120 transmits second stationary behavior information to the vehicle 110.

[0056] For example, the mobile terminal 120 may transmit the second stationary behavior information to the vehicle 110 via a Bluetooth antenna, a UHF antenna, or the like.

[0057] If the vehicle 110 receives the second stationary behavior information from the mobile terminal 120, in step S350, the vehicle 110 transmits a warning signal to the user indicating that the state of the opening / closing member is being switched. For example, the warning signal transmitted by the vehicle 110 may include a warning signal such as a flashing vehicle light, a horn, or a voice prompt through a speaker.

[0058] Also, in step S360, the mobile terminal 120 continues to detect whether the mobile terminal 120 remains stationary for a third predetermined period of time.

[0059] If it is detected that mobile terminal 120 has remained stationary for the third predetermined period, then in step S370, mobile terminal 120 transmits first stationary behavior information to vehicle 110. Here, the third predetermined period may be understood as the difference between the first predetermined period and the second predetermined period. That is, in step S370, if it is detected that mobile terminal 120 has remained stationary for the first predetermined period, mobile terminal 120 transmits the first stationary behavior information.

[0060] If the vehicle 110 receives the first stationary behavior information within the predetermined period, in step S380, the vehicle 110 switches the opening / closing member 112 between the open state and the closed state.

[0061] If the mobile terminal 120 does not detect that it has remained stationary for a third predetermined period of time, i.e., the vehicle 110 If the vehicle 110 does not receive the first stationary behavior information within the predetermined period, in step S390, the vehicle 110 stops transmitting the warning signal, and returns to step S330, where the mobile terminal 120 restarts detecting the stationary behavior of the mobile terminal 120.

[0062] The user may unintentionally remain stationary within the predetermined spatial range. To prevent the state of the opening / closing member 112 from being switched due to such unintentional stationary motion, the method further includes a step of transmitting a warning signal to the user before switching the state of the opening / closing member 112. If the user remains stationary within the predetermined spatial range for a second predetermined period, the mobile terminal 120 transmits second stationary behavior information to the vehicle 110. If the vehicle 110 receives the second stationary behavior information, the vehicle 110 transmits a warning signal to the user indicating that the state of the opening / closing member 112 will be switched. If the user receives the warning signal, the user can remain stationary to communicate an instruction to the vehicle to switch the state of the opening / closing member, or can move to communicate an instruction to the vehicle not to switch the state of the opening / closing member.

[0063] Also, in step S350, as a supplement to or alternative to the vehicle 110 transmitting the warning signal, the warning signal may be transmitted by the mobile terminal 120. The warning signal transmitted by the mobile terminal 120 may include an audible or visual warning signal, such as a transmitted warning sound or flashing light. Because the mobile terminal 120 is typically carried by a user, in certain cases, the warning signal transmitted by the mobile terminal 120 is more likely to be noticed by the user. If the vehicle 110 and the mobile terminal 120 transmit warning signals simultaneously, a typical redundancy scheme prevents the user from noticing the warning signal.

[0064] By rationally setting the second and third predetermined periods, it is possible to accurately determine the user's intention, avoid misjudgment, shorten the user's waiting time, and improve the system sensitivity.

[0065] When the opening / closing member 112 is in the open state, the second predetermined period is the second opening predetermined period. When the opening / closing member 112 is in the closed state, the second predetermined period is the second closing predetermined period. When the opening / closing member 112 is in the open state, the third predetermined period is the third opening predetermined period, and when the opening / closing member 112 is in the closed state, the third predetermined period is the third closing predetermined period.

[0066] In one example, the second predetermined period for opening may be shorter than the second predetermined period for closing. For example, the second predetermined period for opening may be set to 2.5 seconds, and the second predetermined period for closing may be set to 3 seconds. For example, when the trunk opening / closing member 112 is in the open position, the user is usually busy organizing their belongings. Therefore, when the opening / closing member 112 is in the open position, the user's stationary behavior is less likely to occur and the time spent stationary is shorter than when the opening / closing member 112 is in the closed position. Therefore, by setting the second predetermined period for opening shorter than the second predetermined period for closing, the sensitivity for determining the user's stationary behavior is improved, the time the user waits for switching is reduced, and the user experience is improved.

[0067] In one example, the third opening predetermined period may be shorter than the third closing predetermined period. For example, the third opening predetermined period may be set to 2 seconds, and the third closing predetermined period may be set to 4 seconds. For example, if the trunk opening / closing member 112 is in the open state, the user is likely to intend to close the opening / closing member 112, and can quickly recognize and react to the trunk being closed after seeing the warning signal. Therefore, setting the third opening predetermined period shorter than the third closing predetermined period improves the sensitivity for determining the user's stationary behavior, shortens the time the user waits for switching, and improves the user experience.

[0068] In another example, the second predetermined period for opening may be longer than the second predetermined period for closing. For example, when the trunk opening / closing member 112 is in the open state, the user is usually busy organizing their luggage. The user may not be carrying the mobile terminal 120 and may place it inside the opening / closing member 112 or in a fixed installation. At this time, the mobile terminal 120 is stationary and may mistakenly trigger the opening / closing member 112 to switch to the closed state. Therefore, by setting the second predetermined period for opening longer than the second predetermined period for closing, mistaken operation of the opening / closing member 112 can be avoided.

[0069] In another example, the third opening predetermined period may be longer than the third closing predetermined period. Thus, for example, when the trunk opening member 112 is in the open state and is about to be closed, the user can be given enough time to check whether an object has been left inside the opening member 112. Also, during the third opening predetermined period, the vehicle 110 can warn the user via a voice prompt to ensure that no object has been left behind.

[0070] Furthermore, when the predetermined spatial range is outside the opening / closing member 112, the second predetermined period is a second external predetermined period, and the third predetermined period is a third external predetermined period. When the predetermined spatial range is inside the opening / closing member 112, the second predetermined period is a second internal predetermined period, and the third predetermined period is a third internal predetermined period.

[0071] In one example, the second external predetermined period may be shorter than the second internal predetermined period, and the third external predetermined period may be shorter than the third internal predetermined period. For example, the second internal predetermined period may be set to 30 seconds, and the third internal predetermined period may be set to 10 seconds. Because situations in which the key is left inside the opening / closing member 112 do not always occur, the user's waiting time is set longer to avoid erroneous determination and improve the accuracy of determining the user's intention.

[0072] FIG. 4 is a diagram illustrating a method of operating the opening / closing member 112 executed by a controller of the vehicle 110 according to an embodiment of the present disclosure.

[0073] As shown in FIG. 4, the method includes a step S410 in which the vehicle-side communication unit 113 determines whether the mobile terminal 120 is within a predetermined spatial range relative to the opening / closing member 112 through interaction with the mobile-side communication unit 123.

[0074] If it is determined that the mobile terminal 120 is within a predetermined spatial range relative to the opening / closing member 112, the vehicle 110 transmits location confirmation information to the mobile terminal 120 in step S420.

[0075] If the location confirmation information has been sent, in step S430, the vehicle 110 continues to monitor second stationary behavior information from the mobile terminal 120 and receives second stationary behavior information from the mobile terminal 120, which second stationary behavior information indicates that the mobile terminal 120 has remained stationary for a second predetermined period of time.

[0076] If the second stationary behavior information has been received, in step S440, the vehicle 110 causes the vehicle-side warning device 114 to transmit a warning signal indicating that the state of the opening / closing member 112 is about to be switched.

[0077] Also, if second stationary behavior information is received, in step S450, vehicle 110 continues to monitor first stationary behavior information from mobile terminal 120 and receives first stationary behavior information from mobile terminal 120, which first stationary behavior information indicates that mobile terminal 120 has remained stationary for a first predetermined period of time.

[0078] If the vehicle 110 does not receive the first stationary behavior information within the predetermined period, the process returns to step S430 , and the vehicle 110 continues to monitor the second stationary behavior information from the mobile terminal 120 .

[0079] If the first stationary behavior information has been received, in step S460, the vehicle 110 switches the opening / closing member 112 between the open state and the closed state.

[0080] 5 is a schematic diagram of a vehicle system according to another embodiment of the present disclosure. For the sake of brevity, the description of steps that are the same as or similar to those in the system shown in FIG. 1 will be omitted.

[0081] 1, the vehicle system includes, in addition to the vehicle, a first mobile terminal 530 and a second mobile terminal 520. For example, the first mobile terminal 530 may be a vehicle key, and the second mobile terminal 520 may be a mobile phone.

[0082] Similar to the system shown in Fig. 510 includes an opening / closing member 512, a vehicle-side communication unit 513, a vehicle-side warning device 514, and a vehicle-side controller 511.

[0083] The first mobile terminal 530 includes a first mobile communication unit 533, a first mobile warning device 534, and a first mobile controller 531. The first mobile communication unit 533 communicates with the vehicle-side communication unit 513 and may include multiple low-frequency communication antennas, multiple Bluetooth® antennas, or multiple UWB communication antennas. The vehicle-side communication unit 513 can determine the location of the first mobile terminal 530 by interacting with the first mobile communication unit 533. The first mobile warning device 534 is configured to transmit a warning signal to a user. The first mobile controller 531 is communicatively connected to the first mobile communication unit 533 and the first mobile warning device 534 and transmits or receives signals to or from these components.

[0084] The second mobile terminal 520 includes a second motion sensor 522, a second mobile communication unit 523, a second mobile warning device 524, and a second mobile controller 521. The second motion sensor 522 is configured to detect whether the second mobile terminal 520 is stationary and may include, for example, at least one of an acceleration sensor, an angular velocity sensor, and a magnetometer. The second mobile warning device 524 is configured to transmit a warning signal to a user. The second mobile communication unit 523 communicates with the vehicle communication unit 513 and may include at least one of a Bluetooth antenna, a UWB communication antenna, a UHF communication antenna, a 2G / 3G / 4G / 5G mobile communication antenna, a Wi-Fi antenna, etc. The second mobile controller 521 is communicatively connected to the second mobile communication unit 523, the second motion sensor 522, and the second mobile warning device 524 to transmit signals to or receive signals from these components.

[0085] The vehicle system shown in FIG. 5 can be used to perform the methods shown in FIGS. 2 and 3, or the vehicle 510 shown in FIG. 5 can be used to perform the method shown in FIG.

[0086] As shown in FIG. 2, for example, in step S210, the vehicle 510 determines whether the first mobile terminal 530 is within a predetermined spatial range relative to the opening / closing member 512. In step S220, the vehicle 510 transmits location confirmation information to the second mobile terminal 520, indicating that the first mobile terminal 530 is within the predetermined spatial range relative to the opening / closing member 512. If the second mobile terminal 520 receives the location confirmation information, in step S230, the second mobile terminal 520 starts detecting whether the second mobile terminal 520 remains stationary for a first predetermined period of time. In step S240, the second mobile terminal 520 transmits first stationary behavior information to the vehicle 510. In step S260, the vehicle 510 determines whether the first mobile terminal 530 leaves the predetermined spatial range. In step S270, the vehicle 510 transmits location departure information to the second mobile terminal 520. If the second mobile terminal 520 receives the location departure information, in step S280, the second mobile terminal 520 stops detecting stationary behavior.

[0087] As shown in FIG. 3 , for example, in step S310, the vehicle 510 determines whether the first mobile terminal 530 is within a predetermined spatial range relative to the opening / closing member 512. In step S320, the vehicle 510 transmits location confirmation information to the second mobile terminal 520 indicating that the first mobile terminal 530 is within the predetermined spatial range relative to the trunk. If the vehicle 510 receives the location confirmation information, in step S330, the second mobile terminal 520 starts detecting whether the second mobile terminal 520 remains stationary for a second predetermined period. In step S340, the second mobile terminal 520 transmits second stationary behavior information to the vehicle 510. In step S360, the second mobile terminal 520 continues to detect whether the second mobile terminal 520 remains stationary for a third predetermined period. In step S370, the second mobile terminal 520 transmits the first stationary behavior information to the vehicle 510. Also, in step S350, as a supplement to and alternative to the vehicle 510 transmitting the warning signal, the warning signal may be transmitted by the first mobile terminal 530 and / or the second mobile terminal 520. In one embodiment, the warning signal may be transmitted by the vehicle, the first mobile terminal, and the second mobile terminal simultaneously.

[0088] As shown in FIG. 4, in step S410, the vehicle-side communication unit 513 determines whether the first mobile terminal 520 is within a predetermined spatial range relative to the opening / closing member 512 through interaction with the first mobile-side communication unit 533. If it is determined that the first mobile terminal 520 is within the predetermined spatial range relative to the opening / closing member 512, in step S420, the vehicle 510 transmits location confirmation information to the second mobile terminal 530. In step S430, the vehicle 110 continues to monitor second stationary behavior information from the second mobile terminal 520 and receives the second stationary behavior information from the second mobile terminal 520. In step S450, the vehicle 510 continues to monitor first stationary behavior information from the second mobile terminal 520 and receives the first stationary behavior information from the second mobile terminal 520. If the vehicle 510 does not receive the first stationary behavior information within a predetermined period, the process returns to step S430, and the vehicle 110 continues to monitor the second stationary behavior information from the second mobile terminal 520.

[0089] In the above method, a first mobile terminal such as a vehicle key is used to determine whether the user is within a predetermined spatial range relative to the opening / closing member, and authentication is performed using the first mobile terminal and the vehicle. At the same time, a second mobile terminal such as a mobile phone carried by the user along with the vehicle key can be used to detect the user's stationary behavior. Furthermore, information such as the first stationary behavior information and the second stationary behavior information can be transmitted to the vehicle via wireless communication between the mobile phone and the vehicle. Therefore, the above method can be implemented using a motion sensor and a warning device in the mobile phone without modifying existing vehicle keys, reducing hardware modifications and costs.
