Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims the benefit of priority to Korean Patent Application No. 10-2014-0110937, filed on Aug. 25, 2014 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

TECHNICAL FIELD

The present disclosure relates to a system for recognizing a passenger and a boarding position in a vehicle capable of recognizing the passenger boarding a vehicle and the boarding position of the passenger in a vehicle by using a wireless signal transmitted and received in the vehicle.

BACKGROUND

With the development of a vehicle related technology, functions of sensing a state of passengers in a vehicle for user convenience and safety have been added and improved. For example, a function of sensing whether a passenger boards a vehicle and displaying a warning about wearing of a seat belt with a warning sound, and the like has been developed. Further, a function of automatically controlling whether an airbag module is deployed depending on whether a passenger boards a vehicle and controlling a size of the airbag module by recognizing an adult and an infant depending on a load has been developed. Further, functions of sensing positions or temperature of passengers in a vehicle to automatically control a cooling and heating system depending on the positions have been developed.

The related art uses a load sensor for sensing whether a passenger boards a vehicle and a load of the passenger. However, the load sensor has a malfunction problem of performing the sensing operation even on an object, not on a person and therefore an infrared sensor such as an infrared camera sensing only a human body is complementarily used.

Further, to apply an emotional air conditioning system depending on a position of a passenger in a vehicle, temperature is measured depending on the position of the passenger in the vehicle using a plurality of indoor temperature measuring sensors, and the like.

Therefore, to recognize a state of a passenger in a vehicle for displaying a warning about the wear of the seat belt, controlling the airbag module, and controlling the air conditioning system, a need exists to complexly use the load sensor, the infrared sensor, and the temperature measuring sensor as described above.

Herein, the beacon signal is a signal which is periodically broadcast to peripheral devices so as to connect a wireless terminal to an access point which is previously accessed. The beacon signal will be described in detail with reference to FIG. 3.

The passenger position determiner 140 determines boarding positions of passengers boarding a vehicle based on an analysis result of the WiFi signal analyzer 120. In detail, when a passenger boards a passenger seat, the WiFi signal transmitted through the transmitter included in the WiFi signal interface 110 determines the boarding position of the passenger using a signal distortion, and the like which is generated due to a body of the passenger boarding the passenger seat.

The passenger determiner 150 specifies the wireless terminal which broadcasts the beacon signal based on an analysis result of the beacon signal analyzer 130 and determines who a passenger possessing the specified wireless terminal is. In detail, the wireless terminal which broadcasts the corresponding beacon signal is specified based on unique information (for example, MAC address) of the wireless terminal included in the beacon signal.

In the system for recognizing a passenger and a boarding position in a vehicle according to the exemplary embodiment of the present disclosure, contents of a determination of a passenger and a boarding position will be described in detail.

First, the beacon signal analyzer 130 or the passenger determiner 150 specifies and recognizes the wireless terminal which broadcasts the corresponding beacon signal based on the MAC address which is the unique information of the wireless terminal included in the beacon signal received by the receiver or an access point connection request list which is retrieved by the wireless terminal. Further, it may be determined who the passengers of the vehicle are by specifying a passenger possessing the recognized wireless terminal.

Further, the WiFi signal analyzer 120 or the passenger position determiner 140 determines the boarding position of the passenger in the vehicle based on at least one of signal distortion, signal attenuation, Doppler effect, signal strength indication (SSI), and multi-path signal analysis of the WiFi signal which is transmitted from the transmitter and is received by the receiver. Herein, the signal distortion, and the like of the WiFi signal may be generated due to the body of the passenger boarding the vehicle or a motion of the body of the passenger.

Contents of the determination of the boarding position of the passenger will be described with reference to FIG. 2. FIG. 2 is a diagram illustrating that a WiFi signal is transmitted and received through a WiFi interface in a vehicle, in the system for recognizing a passenger and a boarding position in a vehicle according to the exemplary embodiment of the present disclosure.

A vehicle 200 includes a transmitter 211 transmitting the WiFi signal and a receiver 212 receiving the transmitted WiFi signal as the WiFi interface. Further, FIG. 2 illustrates the state in which passengers possessing mobile phones 221 and 222 are currently boarded in a driver's seat and a right back seat in the vehicle 200.

The WiFi signal transmitted from the transmitter 211 is distorted or attenuated due to the body of the passenger of the driver's seat possessing the mobile phone 221 and the body of the passenger of the back seat possessing the mobile phone 222 and the motions of the bodies of the passengers. Further, the so distorted or attenuated degree has a constant pattern depending on the boarding position of the vehicle 200 or the motion of the passenger at the corresponding boarding position.

Referring to FIGS. 1 and 2, in the system for recognizing a passenger and a boarding position in a vehicle, the WiFi signal analyzer 120 or the passenger position determiner 140 may determine the boarding position of the passenger boarding the vehicle based on at least any one of a change pattern of the received WiFi signal due to the body of the passenger which is positioned at a boarding point of the vehicle 200, a change pattern of the received WiFi signal due to the motion of the body of the passenger, and a change pattern of the received WiFi signal which is generated when the passenger gets off. These change patterns are based on the pattern of the WiFi signal received by the receiver 212 when there are no passengers in the vehicle 200.

FIG. 3 is a diagram illustrating the beacon signal transmitted from a wireless terminal in a vehicle, in the system for recognizing a passenger and a boarding position in a vehicle according to the exemplary embodiment of the present disclosure.

A probe request of the beacon signal includes a MAC address 310 which is the unique information of the wireless terminal and connection request lists 320 and 310 which are retrieved by the access point, which is previously accessed, from the wireless terminal. Thereby, in the system for recognizing a passenger and a boarding position in a vehicle according to the exemplary embodiment of the present disclosure, the beacon signal analyzer 130 or the passenger determiner 150 may specify and recognize the wireless terminal which broadcasts the corresponding beacon signal, such that it may be determined who the passenger possessing the corresponding wireless terminal is. Here, as illustrated in FIG. 3, the beacon signal analyzer 130 or the passenger determiner 150 may determine whether the wireless terminal broadcasting the corresponding beacon signal is a wireless terminal which is positioned inside the vehicle or a wireless terminal which is positioned outside the vehicle, based on the repetition of the same beacon signal.

Referring back to FIG. 1, the system for recognizing a passenger and a boarding position in a vehicle according to the exemplary embodiment of the present disclosure may further include the passenger number and position determiner 160 and the vehicle information provider 190.
