Description

USER DEVICE, METHOD FOR CONTROLLING USER DEVICE, VEHICLE, METHOD FOR CONTROLLING VEHICLE, SYSTEM AND METHOD FOR CONTROLLING VEHILCE BY USING USER DEVICE}

The present invention relates to a user terminal, a user terminal control method, a vehicle, a vehicle control method, and a vehicle control system and method using a user terminal, and more specifically, to a user terminal for controlling a vehicle through a user terminal using Bluetooth low energy communication (BLE), UWB (Ultra-Wide Band) communication, and acoustic wave communication, a user terminal control method, a vehicle, a vehicle control method, and a vehicle control system and method using a user terminal.

Recently, automobile manufacturers are actively developing technologies that can control vehicles using smartphones. In particular, technologies for systems that can control vehicles using user terminals using Bluetooth low energy communication and UWB communication technologies are being actively developed.

However, Bluetooth low energy communication uses a high frequency of 2.4 GHz and a narrow bandwidth (2 MHz), so it is greatly affected by environmental factors, and as a result, it has the limitation of being difficult to accurately determine the location of the user device in real time.

In order to improve such problems, UWB communication technology is applied to solve the above problems, but UWB communication has the limitation that it consumes a lot of current because it is a wide-bandwidth communication base. In addition, there is the limitation that users who own user devices that are not equipped with UWB communication technology cannot control their vehicles through their devices. Therefore, there is a need for technology development that can solve the above problems.

In other words, if the user terminal (10) is within the first area, the RSPA function that allows the vehicle (20) to be parked remotely through the user terminal (10) can be performed, and the PKE function that allows the vehicle (20) to be entered and exited without remotely pressing a button around the vehicle (20) can be performed. In addition, if the user terminal (10) is within the second area, the RKE function that allows the vehicle (20) to be opened and closed remotely and the trunk of the vehicle (20) to be opened and closed remotely through the user terminal (10) and the remote start function that allows the vehicle (20) to be turned on and off remotely can be performed.

Referring to FIG. 7, the process of determining the location of a user terminal (10) in a vehicle (20) control system using a user terminal (10) according to one embodiment of the present invention is described as follows.

First, when an application for performing the RKE function, remote start function, and RSPA function of a vehicle (20) remotely is installed on a user terminal (10), the application is executed, and when the user terminal is recognized through the second Bluetooth communication module (21) and pairing information and authentication information are transmitted from the user terminal (10), the second control unit (24) performs primary user authentication based on the pairing information and authentication information of the user terminal (10) stored in the storage unit (25).

When the user's primary authentication is completed, the second control unit (24) wakes up the second UWB communication module (23) and the second sound wave communication module (22) using signals received from the user terminal (10) as triggers, and can determine whether the user terminal (10) is in the first area based on communication between the second UWB communication module (23) and the user terminal (10).

Here, the second control unit (24) calculates a distance value between the user terminal (10) and the second UWB communication module (23) using a known ToF (Time of Flight) TWR (Two Way Ranging) positioning technology according to an embodiment, and estimates a final distance value between the user terminal (10) and the second UWB communication module (23) using the calculated distance value using LQI, Magnitude, and Moving average filtering methods.

Referring to Fig. 8, the process of determining whether the user terminal (10) is in the first area based on communication between the second UWB communication module (23) and the user terminal (10) will be described in more detail as follows.

First, the second control unit (24) calculates the distance values between the user terminal (10) and the second UWB communication module (23) multiple times using the known ToF (Time of Flight) TWR (Two Way Ranging) positioning technology, performs LQI filtering among the calculated multiple distance values to derive X distance values higher than a preset LQI, performs Magnitude filtering among the calculated multiple distance values to derive Y distance values that match the preset Magnitude, and then selects five overlapping distance values among the X and Y distance values, calculates the final distance between the user terminal (10) and the second UWB communication module (23) based on triangulation/triangulation of the selected five distance values, and determines whether the user terminal (10) is in the first area based on the calculated final distance. Here, the TWR positioning formula using ToF, LQI, Magnitude, Moving average filtering formula, and triangulation/triangulation method are well-known technologies, so a detailed description thereof will be omitted.

Meanwhile, the second control unit (24) determines whether the user terminal (10) is in the first area according to the above-described method, and if the user terminal (10) is in the first area and a Bluetooth connection is established between the vehicle (20) and the user terminal (10), if a PKE or RSPA control command is received from the user terminal (10), the received PKE or RSPA control command can be executed.

In other words, when the user terminal (10) is in the first area and a Bluetooth connection is established between the vehicle (20) and the user terminal (10), if a PKE or RSPA control command is received from the user terminal (10), the second control unit (24) can remotely park the vehicle (20) or allow entry and exit of the vehicle (20) without remotely pressing a button around the vehicle (20).

Meanwhile, if the second control unit (24) determines that the user terminal (10) is not in the first area, it can receive encrypted data transmitted from the user terminal (10) through the second sound wave communication module (22), decrypt the received encrypted data, and then perform secondary user authentication by comparing the decrypted data with the encrypted information previously stored in the storage unit (25).

In addition, referring to FIG. 9, the second control unit (24) performs the user secondary authentication according to the above-described method, and then determines whether sound waves are received from the user terminal (10) at a certain period through the second sound wave communication module (22), and depending on whether sound waves are received, determines whether the user terminal (10) is in the second area or the third area.

Here, the second control unit (24) can determine that the user terminal (10) is in the second area if sound waves are not received from the user terminal (10) at a certain period through the second sound wave communication module (22), and can determine that the user terminal (10) is in the third area if sound waves are received from the user terminal (10) at a certain period through the second sound wave communication module (22).

Furthermore, the second control unit (24) can cause the received RKE or remote start control command to be executed when the user terminal (10) is in the second area and a Bluetooth connection is established between the vehicle (20) and the user terminal (10), if an RKE or remote start control command is received from the user terminal (10).

In other words, when the user terminal (10) is in the second area and a Bluetooth connection is established between the vehicle (20) and the user terminal (10), if an RKE (Remote Keyless Entry) or remote start control command is received from the user terminal (10), the second control unit (24) can remotely turn the vehicle (20) on/off or remotely open or close the doors and trunk of the vehicle (20).

Meanwhile, the sound wave communication used in the present invention may use inaudible sound waves of high frequency that are difficult for humans to hear, and data communication may be possible through sound waves between devices or apparatuses on which software applications are installed.

FIG. 10 is a flowchart of a vehicle (20) control method using a user terminal (10) according to an embodiment of the present invention.

More specifically, in step (3-1), the distance between the vehicle (20) and the user terminal (10) is calculated based on the TWR (Two Way Ranging) positioning technology using ToF (Time of Flight), and based on the calculated result, it can be determined whether the user terminal (10) is in the first area.

In addition, step (3-3) may include a step of determining whether sound waves are received from the user terminal (10) at a regular interval through the second sound wave communication module (22); and a step of determining that the user terminal (10) is in the second area if sound waves are not received, and a step of determining that the user terminal (10) is in the third area if sound waves are received.

In addition, in step (4), if it is determined that the user terminal (10) is in the first area and a Bluetooth connection is established between the vehicle (20) and the user terminal (10), if a PKE or RSPA control command is received from the user terminal (10), the received PKE or RSPA control command can be executed.

Meanwhile, the specific technical features at each stage of the vehicle control method using the user's terminal are identical to the technical features of the detailed configuration of the vehicle control system using the user's terminal described above, so a detailed description thereof will be omitted.
