[0028] Fig. Figure 1 is a block diagram representing a vehicle system in which a pulse measuring device according to an embodiment of the present disclosure is used.

[0029] Referring to Fig. 1. According to one embodiment of the present disclosure, the vehicle system may comprise a vehicle device 10 and a pulse measuring device 100.

[0030] The vehicle equipment 10 can communicate with the pulse measuring device 100 and can provide information from a user to the pulse measuring device 100.

[0031] The pulse measuring device 100 can be a device that measures the pulse of a user traveling in a vehicle in a contactless manner. For example, the pulse measuring device 100 can be installed in a seat in the vehicle and measure the pulse of the user sitting in the seat.

[0032] The pulse measurement device 100 can store pulse information of the user and can analyze the stored average pulse of the user, thereby learning pulse information of the user.

[0033] In this case, the pulse measuring device 100 can set a frequency band of a signal for pulse measurement based on pulse information learned according to the user and can measure a pulse of the user based on a signal received in the set frequency band.

[0034] The pulse measurement device 100 can receive user information from the vehicle equipment 10, which is in communication with the pulse measurement device 100, and can recognize the user from the received information. If the recognized user is a previously registered user, the pulse measurement device 100 can retrieve the learned pulse information of the recognized user.

[0035] If the identified user, based on user information received from the vehicle 10, is not the pre-registered user, the pulse measurement device 100 can measure the user's pulse and analyze their average pulse. In this case, the pulse measurement device 100 can register the received user information and store pulse information according to the registered user information.

[0036] A detailed description of the configuration of the pulse measurement device 100 follows, with reference to Fig. 2.

[0037] The pulse measuring device 100 according to an embodiment of the present disclosure can be implemented in a vehicle. In this case, the pulse measuring device 100 can be combined with internal control units of the vehicle.

[0038] Alternatively, the pulse measuring device 100 can be implemented to be independent of the vehicle's control unit and can be connected to the internal control units through a separate connection device.

[0039] Fig. Figure 2 is a block diagram showing a configuration of a pulse measuring device according to an embodiment of the present disclosure.

[0040] Referring to Fig. 2. A pulse measuring device 100 can comprise a control unit 110, a communicator 120, a filter 130, a memory 140, a user recognition device 150, a setting device 160, a pulse detector 170 (pulse finder 170), and a learning device 180. The control unit 110, the setting device 160, the pulse finder 170, and the learning device 180 of the pulse measuring device 100 according to one embodiment of the present disclosure can be implemented as one or more processors.

[0041] The control unit 100 can process a signal that is transmitted between the elements of the pulse measuring device 100.

[0042] The Communicator 120 can include a communication module to support a communication interface with electronic units and / or control units located on a vehicle. As an example, the communication module can communicate with at least one vehicle unit 10. Fig. 1. The communication module can be connected and receive user information from the vehicle equipment 10. The communication module may include a module to support vehicle network communication, such as Controller Area Network (CAN) communication, Local Area Network (LIN) communication, and FlexRay communication. Furthermore, the communication module may include a module for wireless internet access or a module for short-range communication. Wireless internet technologies may include wireless local area networks (WLAN), wireless broadband networks (WiBro), wireless fidelity (Wi-Fi), World Interoperability for Microwave Access (WiMAX), and the like. Short-range communication technologies may include Bluetooth, ZigBee, ultra-wideband (UWB), radio frequency identification (RFID), infrared data mapping (IrDA), and the like.

[0043] The communicator 120 can transmit a radio wave signal to a user using a Doppler system and can receive a signal reflected by the user, thereby transmitting the received signal to the control unit 110.

[0044] The communicator 120 can include a transmitter 121 for transmitting a first pulse measurement signal to the user and a receiver 125 for receiving a second signal, in which the first signal transmitted by the transmitter 121 is reflected by the user. For example, the first signal can be a radio wave signal in the 24 GHz band. The second signal can be a signal from a variety of bands.

[0045] Filter 130 can extract a signal according to a predefined frequency band from the second signal received by receiver 125 and can block a signal of another band. For example, filter 130 can extract a signal of a predefined reference band (hereinafter referred to as a "first frequency band") from the second signal received by receiver 125 and can block a signal according to the other frequency band. The signal extracted by filter 130 can be transmitted to control unit 110.

[0046] A predefined frequency band set in the filter 130 can be set by the setting device 160. In this case, the filter 130 can extract a signal of a frequency band (hereinafter referred to as the "second frequency band") set by the setting device 160 from the second signal received via the receiver 125 and can transmit the extracted signal to the control unit 110.

[0047] Filter 130 can be implemented in the form of a hardware module. According to one embodiment, filter 130 can be implemented in the form of a software module.

[0048] Memory 140 can store data, an algorithm and / or the like that are necessary to operate the pulse measuring device 100.

[0049] Memory 140 can store information according to a first frequency band of filter 130 and can store information from a second frequency band set by the setting device 160. Furthermore, memory 140 can store registered user information and can store pulse information stored in response to user input and / or pulse information learning data.

[0050] Memory 140 can store an instruction and / or an algorithm for determining a user's pulse based on a received signal or for analyzing an average user pulse from the captured pulse information. Memory 140 can also store a learning algorithm for learning user pulse information.

[0051] The memory 140 can include storage media such as a working memory (RAM), a static RAM (SRAM), a read-only memory (ROM), a programmable ROM (PROM), and an electronically erasable PROM (EEPROM).

[0052] If a pulse measurement event occurs, the user identification device 150 can identify the user. The user identification device 150 can identify the user based on information entered by the user. The user identification device 150 can receive user information from the vehicle device 10, which is connected via the communicator 120. The user identification device 150 can identify the user based on the user information received from the vehicle device 10.

[0053] The user identification device 150 can determine whether the identified user is a pre-registered user. If it is determined that the identified user is the pre-registered user, the user identification device 150 can transmit information about the identified user and the user's registration information to the setting device and / or the control unit 110.

[0054] If it is determined that the identified user is not the previously registered user, the user identification device 150 can transmit the information about the identified user via the setting device 160 and / or the control unit 110. The user identification device 150 can register information about the identified user in the memory 140 depending on a request from the user.

[0055] The setting device 160 can adjust a frequency band of a signal passing through the filter 130. If the user detected by the user recognition device 150 is an unregistered user, the setting device 160 can adjust the frequency band of the filter 130 to a predefined first frequency band. Even though there is no pulse information learned in response to the user detected by the user recognition device 150, the setting device 160 can still adjust the frequency band of the filter 130 to the predefined first frequency band.

[0056] If the user identified by the user recognition device 150 in this disclosure is the pre-registered user and if there is pulse information learned in response to the user, the setting device 160 can set a frequency band of the filter 130 based on the pulse information learned in response to the user.

[0057] If a frequency band of the filter 130 is set to the first frequency band or a second frequency band by the setting device 160 when a pulse measurement event occurs, the control unit 110 can control the transmitter 121 to transmit a first signal through the transmitter 121 for a predetermined period of time. If a signal of the first frequency band or the second frequency band, extracted by the filter 130 from a second signal extracted in response to the first signal transmitted for the predetermined period of time, is received, the control unit 110 can store the received signal in the memory 140 and can transmit the stored signal to the pulse detector 170.

[0058] The pulse detector 170 can measure a pulse from signals of the first frequency band or the second frequency band extracted by the filter 130 and can analyze an average pulse, thereby determining pulse information for the user. The pulse detector 170 can store the determined pulse information for the user in memory 140 and can output the stored information.

[0059] If the filter's frequency band is set to the first frequency band, the pulse detector 170 can analyze signals from the first frequency band extracted by filter 130 to measure a pulse, and can analyze an average pulse to determine user pulse information.

[0060] If the frequency band of filter 130 is set according to the second frequency band, which is determined based on training data from previous pulse information provided by the user, the pulse detector 170 can analyze signals from the second frequency band extracted by filter 130 to measure a pulse and can analyze an average pulse to determine the user's pulse information. The second frequency band can be determined from training data based on previous pulse information provided by the user.

[0061] The Pulse Detector 170 can output the user's pulse information to a control system in a vehicle connected via the Communicator 120. The control system in the vehicle can be a system that performs corresponding operations based on the user's biometric information. Furthermore, the Pulse Detector 170 can output the user's pulse information to a display device in the vehicle connected via the Communicator 120.

[0062] The learning unit 180 can learn pulse information from the user, determined based on signals from the first or second frequency band, and can generate learning data based on the learning result. In this case, the generated learning data can be stored as a response to information from the user registered in the memory unit 140.

[0063] If no learning data has been previously stored in response to the user, the learning device can learn 180 pulse information from the user, determined by signals from the first frequency band, and generate learning data based on the learning outcome. If learning data has been previously stored in response to the user, the learning device can learn 180 pulse information from the user, determined based on signals from the second frequency band and the previously stored learning data. The learning device can update learning data stored in memory 140 based on the learning outcome. The learning data stored in response to the user can be updated whenever a user pulse is measured.

[0064] The learning device 180 can learn the user's pulse information using a learning algorithm located in the pulse measuring device 100. The learning device 180 can receive a learning result regarding the user's pulse information from an external learning server connected via the communicator 120 and can generate learning data for the user's pulse information based on the received learning result.

[0065] The pulse measuring device 100 according to an embodiment of the present disclosure, which performs the above-mentioned operation, can be implemented in the form of an independent hardware device comprising a memory and a processor for processing each operation, or can be powered in the form in which it is included in another hardware device, such as a microprocessor or a general-purpose computer system.

[0066] Fig. Figure 3 is a block diagram representing a configuration of a vehicle equipment 10 according to an embodiment of the present disclosure.

[0067] The vehicle equipment 10 can be in communication connection with a pulse measuring device 100 by Fig. 1 and can provide user information to the pulse measurement device 100. The vehicle equipment 10 can transmit and receive a signal with the pulse measurement device 100 in a vehicle network communication mode, a wireless intercommunication mode, and / or a short-range communication mode.

[0068] Referring to Fig. 3. The vehicle 10 may include an intelligent key control device 11 for providing a key identifier (ID) of an intelligent key to the pulse measurement device 100. The vehicle device 10 may also include a vehicle communication device 12, which is in communication link with a user terminal in a wireless communication mode in a vehicle to provide information registered in the user terminal to the pulse measurement device 100. The vehicle device 10 may also include a seat control device for providing information from the user, who is registered in a seat system with a storage system, such as an integrated storage system (IMS), to the pulse measurement device 100 and / or the like. Apart from the devices mentioned above, the vehicle device 10 may include any device for providing information from the user.

[0069] Fig. 4A and Fig. 4B are drawings that depict an operation of the pulse measuring device according to an embodiment of the present disclosure.

[0070] Fig. 4A represents an operation of measuring a user's pulse if a filter's frequency band is not set according to a first frequency band. Fig. 4B represents an operation of measuring a user's pulse if a frequency band of a filter is set to a second frequency band.

[0071] Assuming that a normal adult's pulse rate is between 50 and 140 beats per minute, the first frequency band can be set based on an average value between 50 and 140 beats per minute. Since pulse rates can vary significantly from user to user, the first frequency band can be set to cover a wider range.

[0072] The second frequency band can be set based on the user's average pulse, which is determined by learning pulse information collected from the user and analyzing this average pulse. The second frequency band can be set to be narrower than the first frequency band.

[0073] As in Fig. As shown in 4A, a pulse measuring device can measure 100 of Fig. 2. Measure a pulse with respect to a reference frequency in the first frequency band if user pulse information is derived from a signal in the first frequency band. If reference 411 denotes a frequency band and reference 415 denotes a frequency at which a user pulse signal is actually detected, the time required by the pulse measuring device 100 to measure a user pulse with respect to reference frequency 411 may be t1.

[0074] As in Fig. As shown in Figure 4B, the pulse measuring device 100 can measure a pulse with respect to a reference frequency in the second frequency band if pulse information from the user is obtained from a signal of the second frequency band.

[0075] If reference 421 denotes a reference frequency band and if reference 425 denotes a frequency at which a user pulse signal is actually detected, a time period required by the pulse measuring device 100 to measure a user pulse with respect to reference frequency 421 may be t2 (where t2 < t1).

[0076] If setting a frequency band of a filter 130 of Fig. 2 according to the second frequency band based on learning data of the pulse information determined by the user, the pulse measuring device 100 can further reduce a pulse measurement time duration from t1 to t2.

[0077] The following is a detailed description of the operation of the pulse measuring device according to an embodiment of the present disclosure, comprising the configuration mentioned above.

In step S120, the pulse measurement device 100 receives data if a user is traveling in a vehicle in step S110. In step S130, the pulse measurement device 100 can recognize a user based on user information received in step S120 and can determine whether the recognized user is a previously registered user.

[0081] If the detected user is not the previously registered user from step S130, the pulse measuring device 100 can measure a pulse of the detected user based on a reference frequency band (a first frequency band) in step S140.

Fig. Save 2.

[0084] In step S170, the pulse measuring device 100 can output the user's pulse information, which was determined in step S170.

[0085] Once the user's pulse measurement is complete, the pulse measuring device 100 can learn the user's pulse information, which was stored in step S160, in step S180. In step S190, the pulse measuring device 100 can store the learned result in memory 140. The result stored in step S190 can be used to set a frequency band of the filter 130 when the user's pulse is measured later.

[0086] If the detected user is the previously registered user in step S130, the measuring device 100 can take a step according to “A”. Fig. 6.

[0087] Referring to Fig. 6. The pulse measuring device 100 can retrieve the learned pulse information of the previously registered user and can select a frequency band of a filter 130 from Fig. 2. Determine in step S210. In step S220, the pulse measuring device 100 can set a frequency band of the filter 130 based on information from the determined frequency band.

[0088] In step S230, the pulse measuring device 100 can measure a user's pulse based on the frequency band (a second frequency band) that was set in step S220.

[0089] In step S230, the pulse measuring device 100 can transmit a first signal to the user for a specified period of time and can measure a pulse of the user from a signal of a set frequency band in a second signal that was reflected by the user.

[0090] In step S240, the pulse measuring device 100 can analyze an average pulse based on the result of the pulse measurement in step S230. In step S250, the pulse measuring device 100 can determine the user's pulse information based on the result of the average pulse analysis in step S240 and can store the determined pulse information in memory 140. Fig. Save 2.

[0091] In step S260, the pulse measuring device 100 can output the user's pulse information, which was determined in step S250.

[0092] In step S270, the pulse measuring device 100 can learn the user's pulse information stored in step S260 and the pulse information previously learned for the user, if the user's pulse measurement was completed. In step S280, the pulse measuring device 100 can store the learned result in memory 140. Fig. Save 2.
