For example, the plurality of user terminals 10, 20, 30 and 40 are a computing device such as a smartphone, a tablet, a laptop, and the like, and may comprise an electronic device performing data communication. Meanwhile, referring to
The vehicle 1 is provided with a plurality of seats 510, 520, 530 and 540 in which a driver and occupants other than the driver may be seated.
In general, a Bluetooth transceiver is provided in a vehicle to perform pairing with a driver's user terminal and a vehicle control may be performed through the driver's user terminal. In this instance, a single Bluetooth transceiver may be provided for each vehicle, and perform one-to-one pairing with a user terminal.
According to an exemplary embodiment, a plurality of Bluetooth modules 110,120, 130 and 140 are provided in the vehicle 1, and thus the user terminals of the driver and occupants inside the vehicle 1 may be paired at the same time. In this instance, each of the plurality of Bluetooth modules 110,120, 130 and 140 may be provided at a position corresponding to each of the plurality of seats 510, 520, 530 and 540. For example, the first Bluetooth module 110 is provided close to the first seat 510 which is a driver's seat, the second Bluetooth module 120 is provided close to the second seat 520 which is a front passenger seat, the third Bluetooth module 130 is provided close to the third seat 530 which is a rear left seat, and the fourth Bluetooth module 140 is provided close to the fourth seat 540 which is a rear right seat.
Bluetooth identification information different from each other is assigned to each of the plurality of Bluetooth modules 110,120, 130 and 140, and terminal identification information different from each other is assigned to each of the plurality of user terminals 10, 20, 30 and 40.
Accordingly, the controller 200 may be configured to identify a seat position of a user terminal generating a control signal based on the Bluetooth identification information and the terminal identification information. Also, the controller 200 may be configured to perform Bluetooth pairing at a seat position of a user carrying a user terminal according to a strength of a Bluetooth signal generated in the user terminal. An algorithm related thereto will be described in detail with reference to
The controller 200 is provided in the vehicle 1, and allows the plurality of Bluetooth modules 110,120, 130 and 140, capable of performing bidirectional communication with the plurality of user terminals 10, 20, 30 and 40, to complete pairing. After pairing, the controller 200 may be configured to generate a control command based on a signal generated in the paired user terminal.
Referring to
The Bluetooth module 100 may be configured to perform Bluetooth connection with the user terminal 10. The Bluetooth module 100 may be configured to perform a series of operations for transceiving data with the user terminal 10, and transmit data received from the user terminal 10 to the controller 200.
The Bluetooth module 100 may be configured to attempt pairing with a plurality of user terminals to receive terminal identification information, or maintain a connection with the plurality of user terminals by approving a pairing request attempted by the plurality of user terminals.
The controller 200 may be configured to generate various control commands based on the data received by the Bluetooth module 100 through the user terminal.
The controller 200 may comprise at least one memory 220 in which a program for performing the above-described operations and operations to be described below is stored, and at least one processor 210 for executing the stored program. When a plurality of memories 220 and a plurality of processors 210 are included, the plurality of memories 220 and the plurality of processors 210 may be integrated into one chip or may be physically separated.
The controller 200 may be configured to identify a position of the user terminal 10 among the plurality of seats 510, 520, 530 and 540 based on the Bluetooth signal received from the Bluetooth module 100. When the seat position of the user terminal 10 is identified, the controller 200 may be configured to perform pairing with the Bluetooth module 100 closest to the user terminal 10.
Meanwhile, the controller 200 may be configured to receive signals from the door sensor 310, the seat sensor 320, and the radar sensor 330.
The door sensor 310 may be configured to detect an open state and a closed state of a door (not shown) hinged to a vehicle body and transmit to the controller 200. Specifically, when the door is changed from the open state to the closed state, the door sensor 310 may be configured to generate a door signal, and transmit the door signal to the controller 200 so that the controller 200 may be configured to determine which seat an occupant is located.
The seat sensor 320 refers to a piezoelectric sensor embedded in a seat and may be provided for each of the plurality of seats 510, 520, 530 and 540. In this instance, the seat sensor 320 may be configured to transmit seat signals different from each other to the controller 200 so that the controller 200 may be configured to determine which seat an occupant is located.
The radar sensor 330 is provided inside the vehicle 1 to perform a rear occupancy alert (ROA) function. The radar sensor 330 monitors biometric information of an occupant, and generates a rear seat signal. The radar sensor 330 generates the rear seat signal and transmits to the controller 200 so that the controller 200 may be configured to determine which seat an occupant is located.
The vehicle 1 detects the user terminal 10 through the Bluetooth module 100 (401), and attempts pairing with the user terminal 10 (402).
The vehicle 1 may be configured to automatically complete pairing with the user terminal 10, and also complete pairing by receiving an acceptance command from a user (403).
The controller 200 may be configured to store terminal identification information assigned to the user terminal 10 (404). The terminal identification information corresponds to data for distinguishing user terminals, when several user terminals are connected at the same time or at different times.
After pairing with the user terminal 10, the controller 200 stores setting information input from the user terminal (405). An application for remotely controlling various functions of the vehicle 1 may be installed in the user terminal 10. A user may be configured to control a variety of convenience devices of the vehicle 1 through the user terminal in which the application is installed. For example, by running the application, the user may be configured to control a height or angle of seat, a wind strength or temperature of air conditioner, a window opening degree, a wind strength of ventilated seat fan, a temperature of seat heating wire, a volume of each speaker, and the like, through a specific interface screen.
The above-described functions may have different settings for each seat position in the vehicle 1. For example, a setting of a memory seat in a driver's seat and a setting of a memory seat in a passenger seat may have different setting values according to settings input by users. Also, a temperature of the seat heating wire for each of the driver's seat, passenger seat and rear seat may be set differently according to input from each user. The controller 200 controls the memory 220 to store the terminal identification information and setting input information input from the user.
The operations of performing Bluetooth pairing with the user terminal 10 by the vehicle 1 have been described. Hereinafter, when pre-stored terminal identification information is recognized after setting information is stored in the vehicle 1 as shown in
The controller 200 detects the user terminal 10 (501). The controller 200 receives a Bluetooth signal generated in the user terminal 10 from the Bluetooth module 100.
The controller 200 compares strengths of the Bluetooth signals received from a plurality of Bluetooth modules (502). As described with reference to
According to an exemplary embodiment, the controller 200 may be configured to identify a seat position of the user terminal 10 based on the strengths of the Bluetooth signals. A position of the user terminal 10 indicates a position of an occupant.
The controller 200 selects the Bluetooth module 100 that receives a Bluetooth signal having a highest strength (503), and performs pairing between the user terminal 10 and the Bluetooth module 100 that receives the Bluetooth signal having the highest strength (504). For instance, when only a driver is in the vehicle 1, pairing between the user terminal 10 and the Bluetooth module 100 located in a driver's seat side is completed, without pairing with the other Bluetooth modules 100.
When pairing is completed, the controller 200 determines the seat position based on the Bluetooth module 100 where pairing with the user terminal 10 is completed (505). For example, when pairing between the user terminal 10 and the first Bluetooth module 110 (refer to
In
The controller 200 detects the plurality of user terminals 10, 20 and 30 (601). The controller 200 receives Bluetooth signals, generated in the plurality of user terminals 10, 20, 30 and 40, from the plurality of Bluetooth modules 110,120, 130 and 140. By receiving the Bluetooth signals through the Bluetooth module 100 and identifying the number of user terminals 10, the controller 200 may be configured to identify the number of occupants inside the vehicle 1. Hereinafter, for convenience of description, a description is made based on the first user terminal 10, the second user terminal 20, the first Bluetooth module 110 and the second Bluetooth module 120, and the embodiment is also applicable even when several user terminals exist.
The controller 200 compares strengths of the plurality of Bluetooth signals received in a single Bluetooth module (602). For example, the first Bluetooth module 110 receives the Bluetooth signal generated in the first user terminal 10 and the Bluetooth signal generated in the second user terminal 20, and the controller 200 compares strengths of the two Bluetooth signals. Likewise, the second Bluetooth module 120 receives the Bluetooth signal generated in the first user terminal 10 and the Bluetooth signal generated in the second user terminal 20, and the controller 200 compares strengths of the two Bluetooth signals. The above operation may be collectively performed by the controller 200.
The controller 200 selects a single user terminal 10 having a Bluetooth signal with a highest strength based on a single Bluetooth module (603). Referring to
The controller 200 selects the user terminal 10 that generates the Bluetooth signal having the highest strength based on any one of the plurality of Bluetooth modules (603) and performs pairing (604).
Accordingly, the controller 200 performs pairing with the user terminal that generates the highest signal strength from among the plurality of user terminals, based on any one Bluetooth module. That is, the controller 200 may be configured to determine a position of the user based on the Bluetooth signal strength. In addition, the controller 200 may be configured to determine the position of the user by additionally referring to signals of various sensors provided in the vehicle 1.
The controller 200 receives a sensor signal (605). In this instance, a sensor comprises the door sensor 310, the seat sensor 320, the radar sensor 330 (refer to
The vehicle 1 according to an exemplary embodiment is provided with the door sensor 310 that detects a closing of a door and generates a door signal. The controller 200 may be configured to determine a seat position of a paired user terminal based on the door signal generated in the door sensor 310. For example, when the door signal is generated at the driver's seat side within a predetermined period of time, the controller 200 may be configured to determine that the user terminal 10 is located in the driver's seat. Also, according to an exemplary embodiment, the controller 200 may be configured to perform pairing based on the above-described Bluetooth signal strength and detection of the door signal. The position of the user may be accurately determined by performing pairing only when the two conditions are satisfied.
The vehicle 1 according to an exemplary embodiment comprises the seat sensor 320 which is provided in each of the plurality of seats, detects a pressure by a driver or occupant and generates a seat signal. The controller 200 may be configured to determine a seat position of a paired user terminal based on the seat signal generated in the seat sensor 310. For example, when a seat signal is generated from the seat sensor 320 embedded in the driver's seat, the controller 200 may be configured to determine that the user terminal 10 is located in the driver's seat. Also, according to an exemplary embodiment, the controller 200 may be configured to perform pairing based on the above-described Bluetooth signal strength and detection of the seat signal. The position of the user may be accurately determined by performing pairing only when the two conditions are satisfied.
The vehicle 1 according to an exemplary embodiment is equipped with a rear occupant alert (ROA) system which is provided in a rear seat among the plurality of seats, detects an occupant sitting in the rear seat and generates a rear seat signal. In this instance, to implement the ROA system, the vehicle 1 is provided with the radar sensor 330. The radar sensor 330 provided in the rear seat detects a rear occupant and generates the rear seat signal. The controller 200 may be configured to determine a seat position of a paired user terminal based on the rear seat signal. Also, according to an exemplary embodiment, the controller 200 may be configured to perform pairing based on the above-described Bluetooth signal strength and detection of the rear seat signal. The position of the user may be accurately determined by performing pairing only when the two conditions are satisfied.
Further, according to an exemplary embodiment, a change in Bluetooth signal strength is detected by any one of the plurality of Bluetooth modules 110,120, 130 and 140, and the controller 200 may be configured to identify a seat position change of the user based on the change in signal strength. For example, when the first Bluetooth module 110 detects that a Bluetooth signal strength of the first user terminal 10 is decreased from 1.5 to 1.0 and the second Bluetooth module 120 detects that a Bluetooth signal strength of the first user terminal 10 is increased from 1.0 to 1.5, the controller 200 may be configured to determine that a user with the first user terminal 10 moves to the second seat 520, end pairing between the first Bluetooth module 110 and the first user terminal 10 and start pairing between the second Bluetooth module 120 and the first user terminal 10.
In addition, according to an exemplary embodiment, the controller 200 may be configured to detect a change in seat signal and determine a movement of seat position of the user terminal 10. For instance, when an occupant moves to a rear right seat from a rear left seat, the controller 200 receives a seat signal from another seat sensor. Based on the above, the controller 200 may be configured to determine that a user of a paired user terminal has moved, and perform pairing with the Bluetooth module 100 located in the changed position. The embodiment may also be implemented based on the rear seat signal generated from the radar sensor 330 in addition to the seat signal. The controller 200 may be configured to detect a change in rear seat signal, determine a movement of seat position of the paired user terminal 10, and perform pairing with the Bluetooth module 100 located in the changed position.
That is, the controller 200 determines the seat position of the user terminal 10 based on at least one of the sensor signals or the Bluetooth signals (606).
According to an exemplary embodiment, when pairing between one of the plurality of Bluetooth modules and one of the plurality of user terminals is completed, the controller 200 may be configured to determine the seat position of the paired user terminal based on Bluetooth identification information and generate a control command according to setting information stored in the paired user terminal. In this instance, the control command corresponds to a control signal for changing or maintaining settings of various devices provided in the vehicle 1 (e.g., a memory seat, air conditioner, window, ventilated seat, seat heating wire, speaker). Control operations after pairing are described with reference to
Prior to the description of the embodiment, when pairing with the user terminal 10 is performed for the first time, the vehicle 1 stores a setting input from the user terminal 10, and then controls various devices according to the stored setting in a seat where the user terminal 10 is located. According to an exemplary embodiment, the user terminal 10 may be configured to receive a setting input for at least one of a memory seat, a seat heating wire, a ventilated seat, an air conditioner or a window, and the controller 200 may be configured to control the memory 220 to store the setting input for each terminal identification information.
The controller 200 receives setting information of the paired user terminal 10 (801). In this instance, the controller 200 may be configured to identify a seat position of the user terminal 10 based on Bluetooth identification information of the Bluetooth module 100 paired with the user terminal 10.
The controller 200 generates a control command according to the setting information (802). In this instance, the control command corresponds to a command for controlling various devices corresponding to the identified seat position. For example, the generated control command corresponds to a control signal for controlling only a memory seat of a driver's seat or only a heating wire of one seat of rear seat.
According to an exemplary embodiment, the controller 200 may be configured to determine the seat position of the paired user terminal 10, and control a memory seat of the determined seat position according to the setting input.
According to an exemplary embodiment, the controller 200 may be configured to determine the seat position of the paired user terminal 10, and control a temperature of seat heating wire of the determined seat position according to the setting input.
According to an exemplary embodiment, the controller 200 may be configured to determine the seat position of the paired user terminal 10, and control a temperature of air conditioner located close to the determined seat position according to the setting input.

The instructions may be stored in the form of a program code, and when executed by a processor, the instructions may be configured to generate a program module to perform operations of the disclosed embodiments. The recording medium may be implemented non-transitory as a computer-readable recording medium.
The computer-readable code can be recorded on a medium or transmitted through the Internet. The medium may comprise read only memory (ROM), random access memory (RAM), magnetic tapes, magnetic disks, flash memories, and optical recording medium.
