The pulse measurement apparatus includes a communicator configured to transmit a first signal to a user and receive a second signal reflected from the user during a predetermined time, a filter configured to extract a signal of a set frequency band from the second signal, a setting device configured to set a frequency band of the filter to a first frequency band or a second frequency band, and a pulse detector configured to measure a pulse from the signal extracted by the filter, analyze an average pulse, and detect pulse information of the user from the analyzed result. ## Claims ### Claim 1 A pulse measurement apparatus, the apparatus comprising: a communicator configured to transmit a first signal to a user and receive a second signal reflected from the user during a predetermined time; a filter configured to extract a signal of a set frequency band from the second signal; a setting device configured to set a frequency band of the filter to a first frequency band or a second frequency band; and a pulse detector configured to measure a pulse from the signal extracted by the filter, analyze an average pulse, and detect pulse information of the user from the analyzed result. ### Claim 2 (depends on 1) The apparatus of claim 1, further comprising a user recognizing device configured to recognize the user based on information of the user who rides in a vehicle. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the setting device is configured to set the frequency band of the filter to the first frequency band when the recognized user is not a previously registered user and set the frequency band of the filter to the second frequency band based on learning data stored in response to the user when the recognized user is the previously registered user. ### Claim 4 (depends on 1) The apparatus of claim 1, further comprising a learning device configured to learn the detected pulse information of the user and generate learning data based on the learned result. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the learning device is configured to store the generated learning data in response to the user. ### Claim 6 (depends on 4) The apparatus of claim 4, wherein the learning device is configured to learn the detected pulse information of the user and the stored learning data when there is learning data previously stored in response to the user and update the stored learning data based on the learned result. ### Claim 7 (depends on 2) The apparatus of claim 2, wherein the user recognizing device is configured to recognize the user based on user information provided from a vehicle device. ### Claim 8 (depends on 1) The apparatus of claim 1, further comprising a storage configured to register information of the user and store the detected pulse information of the user in response to the registered information of the user. ### Claim 9 A pulse measurement method, the method comprising: setting a frequency band of a filter to a first frequency band or a second frequency band; transmitting a first signal to a user; receiving a second signal reflected from the user during a predetermined time; extracting a signal of a frequency band set in the filter from the second signal; and measuring a pulse from the extracted signal, analyzing an average pulse, and detecting pulse information of the user from the analyzed result. ### Claim 10 (depends on 9) The method of claim 9, further comprising recognizing the user based on information of the user who rides in a vehicle before the setting. ### Claim 11 (depends on 10) The method of claim 10, wherein the setting comprises setting the frequency band of the filter to the first frequency band when the recognized user is not a previously registered user and setting the frequency band of the filter to the second frequency band based on learning data stored in response to the user when the recognized user is the previously registered user. ### Claim 12 (depends on 9) The method of claim 9, further comprising: learning the detected pulse information of the user; generating learning data based on the learned result; and storing the generated learning data in response to the user. ### Claim 13 (depends on 9) The method of claim 9, further comprising: learning the detected pulse information of the user and stored learning data when there is learning data previously stored in response to the user; and updating the stored learning data based on the learned result. ### Claim 14 (depends on 10) The method of claim 10, wherein the recognizing of the user comprises recognizing the user based on user information provided from a vehicle device. ### Claim 15 (depends on 10) The method of claim 10, further comprising: registering information of the recognized user when the recognized user is not a previously stored user; and storing the detected pulse information of the user in response to the registered information of the user. ### Claim 16 A vehicle system, comprising: at least one vehicle device configured to recognize a user who rides in a vehicle and provide information of the user; and a pulse measurement apparatus configured to recognize the user based on the information of the user received from the at least one vehicle device, set a frequency band of a filter to a first frequency band or a second frequency band based on information of the recognized user, and detect pulse information of the user based on a signal extracted from the signal reflected from the user by the filter when measuring a pulse of the user. ### Claim 17 (depends on 16) The vehicle system of claim 16, wherein the pulse measurement apparatus is configured to set the frequency band of the filter to the first frequency band when the recognized user is not a previously registered user and set the frequency band of the filter to the second frequency band based on learning data stored in response to the user when the recognized user is the previously registered user. ### Claim 18 (depends on 16) The vehicle system of claim 16, wherein the pulse measurement apparatus is configured to output the detected pulse information of the user to at least one of a control system or a display device in the vehicle. ### Claim 19 (depends on 16) The vehicle system of claim 16, wherein the at least one vehicle device includes at least one of a smart key control device, a vehicle communication device, and a seat control device. ### Claim 20 (depends on 16) The vehicle system of claim 16, wherein the pulse measurement apparatus is configured to be installed in a seat of the vehicle and measure a pulse of a user who sits on the seat by a radio wave signal.
