## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of priority to Korean Patent Application No. 10-2015-0157198, filed on Nov. 10, 2015 with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
TECHNICAL FIELD
Embodiments of the present disclosure relate to a technology for detecting a driver who will actually drive a vehicle when a single vehicle is driven by multiple people and providing information on the detected driver.
BACKGROUND
An automobile is often used as transportation. The number of people using automobiles is increasing. Although in the past, an automobile has had no more significance beyond a means for transportation, with the development of electronic and communication technologies, various convenience systems for improving the convenience of users are being developed by applying the electronic and communication technologies to the automobiles.
As a representative example of such systems, an integrated memory system (IMS) allows a driver to store positions of a seat or a mirror and a steering wheel, etc., wherein when the positions of the seat, back mirror, etc. do not fit due to the car having been driven by a different driver, a button is pressed to automatically adjust the seat, back mirror etc. according to the driver's position.
Also, a cluster design selection (CDS) system consists of a display such as a liquid crystal display (LCD) to allow selecting cluster images according to each driver's preference.
Generally, when a single automobile is co-used by a plurality of drivers, each driver gets in a vehicle and sets a vehicular environment in a corresponding system according to each body condition and stores the settings in a memory button so as not to overlap with other drivers. Then, when a driver is changed, the original driver's information is recalled using the memory button.
However, in such a conventional convenience system described above, unless a user name is directly written on a button, which button belongs to the driver can be confusing, making it necessary to press many buttons or to reset the system.
Also, since it is possible by mistake to over-write an existing memory button set by another driver so that afterwards when another driver presses the memory button, it is necessary to again reset because the setting has changed from the original setting.
Also, when a single vehicle is co-used by a plurality of people, it is impossible to precisely determine who the actual driver of the vehicle currently is, and problems may occur when the vehicle is parked or an emergency occurs. That is, since only one designated contact information is externally displayed in a generally used notice method, when the contact information displayed externally is not that of the actual driver, problems may result. Also, in such a notice method, since it is always possible to see contact information inside a vehicle, there is a disadvantage in that personal information is easily exposed even when unnecessary.
Accordingly, it is necessary to develop a technology capable of automatically providing information on a driver who will actually drive by precisely determining the driver who will actually drive the vehicle and or easily recalling stored information while overcoming such limitations.
SUMMARY OF THE DISCLOSURE
Therefore, it is an aspect of the present disclosure to provide a technology of detecting a person who will actually drive a vehicle using a smart key of the vehicle and an external device without installing an additional device and automatically providing information on a driver externally or setting a vehicular environment according thereto.

The jog dial 60 may not only perform a driving operation by applying pressure or rotating but also may include a touch pad with a touch recognition function to perform writing recognition for the device operation using a finger of the user or a separate tool with a touch recognition function.
A steering device which operates the driving of a vehicle may include a steering wheel 42 which receives a driving direction input from the driver, a steering gear (not shown) which converts a rotary motion of the steering wheel 42 into a reciprocating motion, and a steering link (not shown) which transfers the reciprocating motion of the steering gear to the front wheels 93. The steering device described above may change the driving direction of the vehicle 1 by changing a direction of a rotating axis of wheel.
A brake system may include a brake pedal (not shown) which receives a braking operation from a driver, a brake drum (not shown) or disc coupled with a wheel, a brake shoe (not shown) or pad which slows a rotation of the brake drum or disc using a frictional force, etc. The brake system described above may brake the driving of the vehicle by stopping the rotation of wheels.
As described above, the external shape and the interior 10 of the vehicle 1 in which the present disclosure is installed will be described with reference to FIGS. 1 and 2. Hereinafter, the present disclosure will be described in detail.
The present disclosure relates to a technology of determining a driver who actually drives using a smart key and an external device and accordingly controlling vehicular information or automatically setting a vehicular environment.
Since the driver who actually drives may be determined using whether the smart key is possessed and the external device, when a single vehicle is driven by multiple people, information may be automatically provided according to the information of the actual driver, and the vehicular environment may be set.
FIG. 3 is a view illustrating an operation process in accordance with one embodiment of the present disclosure.
The smart key periodically transmits identification information to the external device. Here, the identification information is a signal having information on the smart key and includes information on the vehicle.
When the identification information is transmitted from the smart key, the external device receives the signal. Here, the external device is generally a smart phone but is not limited thereto and may include other external devices capable of receiving identification information and transmitting driver information corresponding thereto to a vehicle.
The external device determines whether the information of the smart key included in the received signal is identical to smart key information pre-stored in the external device. Since drivers who drive the vehicle before the external device receives the signal from the smart key pre-store the smart key information in the external device, respectively, it is possible to determine whether the information transmitted from the smart key is identical to the smart key information pre-stored in the external device.
When the information of the smart key included in the signal received by the external device is identical to the smart key information pre-stored in the external device, the user using the external device may be determined as the driver who actually drives the vehicle, and the information of the determined driver may be transmitted.
A communication unit of the vehicle may receive the information of the driver using a telematics server. The external device may transmit the information of the driver to the vehicle through the telematics server using a communication technology such as mobile communication, etc.
The vehicle receives the information of the driver and, when the received information of the driver has been pre-stored, may display driver information set by the driver or automatically control various devices in the vehicle according to the standards set by the driver.
As shown in FIG. 3, for example, the name and phone number of the driver who will drive the vehicle may be externally displayed, and a seat of the vehicle may be adjusted according to the driver who will drive the vehicle. The above-cited drawing illustrates adjusting the seat in the vehicle. However, the disclosure is not limited thereto. Various devices installed in the vehicle such as a brake pedal, mirrors, a cluster design, etc. may be adjusted as well.
FIG. 4 is a control block diagram illustrating components of a device installed in the vehicle for providing information of a driver in accordance with one embodiment of the present disclosure.
The present disclosure (1000) may include a smart key 100 which communicates with a communication unit 200 and an external device 500, the communication unit 200 which receives various pieces of information from the smart key 100 and the external device 500, and a control unit 300 which transmits to the display unit 400 information set by the driver based on driver information received from the communication unit 200 or controls a vehicular environment according to information set by a user.
The smart key 100 may transmit and receive signals with the external device 500 and the communication unit 200. In the present disclosure, since information of a driver who will actually drive a vehicle is provided to the communication unit 200 using the external device 500, the smart key 100 may communicate not only with the communication unit 200 of the vehicle but also with the external device 500.
Accordingly, the smart key 100 may include a communication module for communicating with the communication unit 200 and the external device 500. The communication module may mean a module for wireless Internet access and local area communication (LAN).
As a wireless Internet technology, wireless LAN (WLAN), wireless fidelity (Wi-Fi), wireless broadband (Wibro), worldwide interoperability for microwave access (WiMax), high speed downlink packet access (HSPDA), etc. may be used. As a LAN technology, Bluetooth, Zigbee, radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), etc. may be included.
Accordingly, the smart key 100 may include various circuit boards and devices necessary for performing such wireless Internet communication and LAN communication described above.
The smart key 100 may periodically generate a signal using the communication module. The signal may include information on the vehicle. As will be described below, the external device 500 may determine using the signal the person who will actually drive the vehicle.
The external device 500 may receive the signal periodically generated by the smart key 100. Also, the external device 500 may determine to which vehicle the smart key 100 corresponds by analyzing the received signal, and then may determine whether the information on the smart key 100 is stored in the external device 500. When the information of the smart key 100 is stored in the external device 500, the external device 500 may determine a user of the external device 500 to be the driver who will actually drive the vehicle and may transmit the information of the driver to the communication unit 200.
Accordingly, the external device 500 capable of performing such functions may generally be a smart phone. In the detailed description of the present disclosure, smart phones most easily obtainable by people will be used for promoting an understanding. However, the external device 500 of the present disclosure is not limited to smart phones and may include other external devices capable of performing such functions described above.
For example, a smart watch, a smart gear, a smart glass, a laptop computer, personal digital assistants (PDA), portable multimedia player (PMP), etc. may be included and used.
The communication unit 200 is a component which wirelessly communicates with the smart key 100 and the external device 500 and may perform the functions of receiving the information of the driver who will actually drive the vehicle and transmitting the information of the driver to the control unit 300.
The communication unit 200 may communicate with the smart key 100 using the wireless Internet technology and the LAN technology described for the smart key 100 and may generally communicate with the external device 500 using a mobile communication network.
Generally, the communication unit 200 may include a telematics terminal (not shown). Telematics is a compound word formed by combining telecommunication and informatics, which indicates a system for transmitting and receiving an e-mail in a vehicle or searching various pieces of information using the Internet. Using the telematics, it is possible to transmit and receive various types of data and images. Accordingly, the communication unit 200 may receive the information of the vehicle and driver using a telematics server.
The control unit 300 may include a storage portion 310 and an IMS control portion 320.
When the information of the driver received from the communication unit 200 is present in the storage portion 310, the control unit 300 may transmit to the display unit 400 information preset by the driver or may control various devices in the vehicle according to the standards set by the driver using the IMS control portion 320.
The storage portion 310 stores information on all drivers who may drive the vehicle. Names and phone numbers of the drivers as well as brake positions, seat positions, cluster designs set by the drivers according to their preferences are stored. In addition, texts, particular phrases, map data, phone books, messages, photos, and moving images stored by the drivers may be stored.
Accordingly, to store the above information, the storage portion 310 may include one or more storage media of a flash memory, a hard disc, a multimedia card micro type memory such as a secure digital (SD) memory card and an extreme digital (XD) memory, a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disc and/or an optical disc.
When the information of the driver received from the communication unit 200 is present in the storage portion 310, the IMS control portion 320 may control various devices in the vehicle according to the standards set by the driver.
The IMS system indicates a system which automatically adjusts a vehicular environment according to a set environment of the vehicle when the driver gets in the vehicle, having already set a vehicular environment suited for the driver. Other names could include a memory system, a driver's seat memory system, etc.
Using the IMS system, even though a single vehicle is used by multiple people and thus positions of seat and mirrors frequently change, it is possible to automatically restore an original state by only operating a memory switch. Accordingly, even when a driver is changed, it is unnecessary to manually operate positions of seat and mirrors one by one.
Accordingly, the IMS control portion 320 of the present disclosure may, using the IMS system, transmit the name and phone number of the driver or the text or phrase stored by the driver to the display unit 400 and may automatically set various devices in the vehicle according to the standards preset by the driver.
The display unit 400 may externally or internally display the information of the driver received from the control unit 300.
Generally, the display unit 400 may display the name or phone number of the driver, a message by the driver to externally inform, for example, phrases such as “parked for a while”, “visitor's vehicle”. Accordingly, since it is necessary to allow the information described above to be externally seen, the display unit 400 may be installed in the rear of the wind screen 11 of the vehicle interior 10. However, the display unit 400 is not limited thereto may be installed anywhere in the vehicle interior 10 or exterior.
Since it is necessary to flexibly display short messages, etc., the display unit 400 may be formed of a device capable of performing such a function. An electronic panel may be used for displaying as well as a lighting device, etc. may be used for displaying.
As described above, components of the present disclosure and the functions of the components have been described. Next, a sequence of operations in the present disclosure will be described in detail with reference to FIG. 5.
FIG. 5 is a flowchart illustrating a process of providing information of a driver and a vehicular environment in a method of controlling a vehicle in accordance with one embodiment of the present disclosure.
Before describing the process in detail, for understanding, it will be assumed that the external device 500 is a smart phone which people may easily obtain. However, as described above, the external device 500 is not simply limited to the smart phone but may also include other devices capable of functioning similarly.
In the present disclosure, before the operation, a driver who will drive a vehicle stores information of the smart key 100 in a smart phone of the driver (S100).
The process is for checking whether identification information transmitted from the smart key 100 matches, and the user stores the information of the smart key 100 in a smart phone. In the case of the smart phone, the information of the smart key 100 may be stored using an application.
When the number of drivers who will use the vehicle is one, the information of the smart key 100 is stored in a smart phone of the only one driver. However, when a single vehicle is driven by multiple drivers, it is necessary to store the information of the smart key 100 in each smart phone.
For example, when the vehicle is driven by X who is an owner of the vehicle and Y who is the wife of the owner, it is necessary to register the information of the smart key 100 in the smart phones of X and Y through an application, respectively. When Y does not register the information of the smart key 100 in Y's smart phone, it is impossible to use the present disclosure.
If the information of the smart key 100 is stored in the smart phone, the smart key 100 periodically generates and transmits identification information to an external device (S200).
The identification information is a signal which includes the information of the smart key 100 and may be transmitted using a wireless communication function.
As a wireless communication technology, the wireless Internet technology and the LAN communication technology described above may be used. As examples, Bluetooth, Wi-Fi, Zigbee communication technologies, etc. may be used.
The identification information is identification information which includes the information of the smart key 100, that is, information on the vehicle. For example, the signal transmitted by the smart key 100 may include information such as model A of H company with a number of 0000.
When the external device is a smart phone, because an application may be used, the signal transmitted by the smart key 100 may be an identification (ID) which includes such information (above) or a password.
When the smart phone receives the signal transmitted from the smart key 100, it is determined whether the information of the smart key 100 included in the signal is identical to the information of the smart key 100 stored in the external device 500 or the smart phone (S300).
That is, the operation described above is an operation to determine whether the driver is a person who has a right to actually drive the vehicle, in which it is determined whether the information of the smart key 100 stored in S100 is identical to the information of the smart key 100 transmitted from the smart key 100 to the external device.
In case that the information of the smart key 100 is matched, the user of the smart phone is determined to be the driver who will actually drive the vehicle. However, when the information of the smart key 100 is not matched, the user of the smart phone is determined not to be the driver who will actually drive the vehicle and S200 is performed again.
When X and Y described above approach the vehicle at the same time with the smart keys 100 with X having stored the information of the smart key 100 in X's smart phone and Y not having stored the information of the smart key 100 in Y's smart phone, even though the smart phones of X and Y respectively receive the signals transmitted by the smart key 100, only the smart phone of X is determined to be the smart phone of the driver who will actually drive.
When the information of the smart key 100 is determined to be identical through S300, the smart phone determines whether a distance between the smart key 100 and the smart phone corresponds to a certain distance or less (S400).
A reason of performing the operation is that if the driver is the person who will actually drive the vehicle, the driver in general carries the smart key 100 and the smart phone at the same time. When the operation is not performed, even though different people have the smart key 100 and the smart phone, they may be recognized as identical.
For example, assume that X described above has the smart key 100 to actually drive and the information of the smart key 100 does not exist in the smart phone of X but is present in the smart phone of Y. Then, when X and Y approach the vehicle at the same time, the smart phone may determine an actual driver to be Y, not X, according to S200 and S300. Therefore, through the process S400, the person who will actually drive may be accurately detected.
When the received information of the driver corresponds to more than one driver, the communication unit 200 may determine the driver closest to the vehicle to be driven to be the driver who will actually drive the vehicle. That is, a person located closest to the vehicle has the highest probability of actually driving the vehicle.
For example, when X and Y each have the smart key 100 and the information of the smart key 100 is stored in each of the smart phones, a condition in which both the X and Y may become the driver is satisfied. Accordingly, in this case, according to the present disclosure, the person located nearest to the vehicle is determined to the actual driver and the information of the driver is transmitted to the vehicle.
Also, when the received information of the driver corresponds to more than one driver, a certain driver may be automatically selected according to preset criteria. The last driver of the vehicle, an owner of the vehicle, a newly determined driver, and/or a certain person designated by the owner of the vehicle may be selected as the driver.
For example, when X is determined to be a priority driver always, even though X and Y each have the smart keys 100 and the information of the smart key 100 is in each of the smart phones, X is determined to be the driver, and information on X is transmitted according to the preset criteria.
When the driver who will actually drive the vehicle is determined according to S400, the smart phone transmits information of the driver to the vehicle (S500).
Since the information may be transmitted using the smart phone, a mobile communication network may be generally used. However, the disclosure is not limited thereto, and transmission may occur using other similar communication technologies.
Since the communication unit 200 includes the telematics terminal, the information of the driver transmitted by the smart phone may be transmitted to the vehicle through the telematics server, and the communication unit 200 may receive the information of the user using the telematics terminal.
When the information of the driver is transmitted, the communication unit 200 receives and transmits the information of the driver to the control unit 300. Also, the control unit 300 provides driver information set by the driver or sets a vehicular environment according thereto (S600).
According to S500, the control unit 300 may transmit information preset by the driver determined to be the driver of the vehicle, for example, a name and a phone number of the driver or frequently used texts to the display unit 400 and may control the vehicular environment using the IMS control portion 320 according to the driver information preset by the driver determined to be the driver of the vehicle.
FIGS. 6 to 8 illustrate the control unit 300 externally displaying the information of the driver using the display unit 400.
FIG. 6 is an external appearance of a display unit in accordance with one embodiment of the present disclosure.
The display unit 400 is a component installed to allow information in the vehicle to be externally seen. Since it is necessary to be easily seen from the outside, the display unit 400 may be generally installed on a windshield of the vehicle but is not limited thereto, and may be installed anywhere in the vehicle interior 10 as long as it is possible to be seen from the outside.
It is necessary for the display unit 400 to externally display the information of the driver and thus may be formed of an electronic panel or an LED lamp. Also, to allow the information of the driver to be visible at night, a lighting unit may be provided at a side portion. Components of the display unit are not limited thereto, but may include other structures similar thereto as long as they are able to externally display the information.
FIG. 7 is a view illustrating the name and phone number of the driver on the display unit 400 in accordance with one embodiment of the present disclosure. FIG. 8 is a view illustrating a certain text on the display unit 400 in accordance with one embodiment of the present disclosure.
FIG. 7 illustrates displaying the name and phone number of Gil-Dong Hong when the driver is determined to be Gil-Dong Hong through the operations in accordance with the embodiment of the present disclosure. Even when the phone number of the driver has been changed, the changed number may be displayed after having been preset.
FIG. 8 illustrates a text frequently used by the driver. When the driver frequently visits a certain building, a particular text and phone number may be exposed without exposing the name of the driver.
Also, it is possible to selectively display only the phone number or certain text depending on the style or message that the driver wants to convey.
FIG. 9 is a view illustrating an example of controlling mirrors, etc. of the vehicle in accordance with one embodiment of the present disclosure.
FIG. 9 illustrates adjusting the side mirrors 91 and 92 and a room mirror 20. Even though adjusting the mirrors 91 and 92 only is shown in FIG. 9, the control is not limited thereto, and various devices in the vehicle may be controlled. For example, position of a seat back-and-forth, tilt of the seat, height of a headrest, left and right angles of side mirrors, height of a steering wheel, position of a brake pedal, etc. may be adjusted.
Also, a cluster design may be selected. A cluster design selection (CDS) system capable of selecting a cluster image according to driver's preferences may be executed also through the control unit 300. Accordingly, the driver may recall a preferable cluster design.
As described above, according to the embodiment of the present disclosure, even when a single vehicle is driven by multiple people, it is possible to detect a driver who will actually drive and to automatically display information on the actual driver accordingly. Also, when a new driver drives, it is unnecessary to reset a vehicular environment according to the new driver, and the vehicular environment is automatically set, thus improving the convenience of driving the vehicle.
As is apparent from the above description, in accordance with one embodiment of the present disclosure when a single vehicle is driven by multiple drivers, a driver who will actually drive the vehicle may be detected using a smart key and an external device, and information on the driver who will actually drive the vehicle may be provided or a vehicular environment may be set according thereto. Accordingly, the present disclosure removes an inconvenience of a new driver having to reset details of a vehicle one by one or to provide his or her information again.
Also, since an existing smart key and an external terminal used by a driver are used, it is possible to implement the present disclosure without an additional device.
Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
