Abstract

A pulse measurement apparatus, a method therefor, and a vehicle system are provided. 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.

First claim

What is claimed is:

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 setting device configured to set a frequency band of a filter to a first frequency band or a second frequency band, the filter configured to extract a signal of the set frequency band from the second signal; 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 average pulse;
a user recognizing device configured to recognize the user based on information of the user who rides in a vehicle;
wherein the setting device is configured to set the frequency band of the filter to the first frequency band when the user is a recognized user but 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 recognized user being the previously registered user,
wherein the previously registered user is registered through user input by the user or from data received from a vehicle device and is stored in a storage.

2. 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 detected pulse information.

3. The apparatus of claim 2 , wherein the learning device is configured to store the generated learning data.

4. The apparatus of claim 1 , wherein the storage is configured to register information of the user and store the detected pulse information of the user in response to registering the information.

5. 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 the set frequency band set in the filter from the second signal; and
measuring a pulse from the extracted signal, analyzing an average pulse from the measured pulse, and detecting pulse information of the user from the analyzed average pulse;
recognizing the user based on information of the user who rides in a vehicle before the setting of the frequency band;
wherein the setting of the frequency band 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.

6. The method of claim 5 , further comprising:
learning the detected pulse information of the user;
generating learning data based on the learned detected pulse information; and
storing the generated learning data in response to the information of the user.

7. The method of claim 5 , wherein the recognizing of the user comprises recognizing the user based on user information provided from a vehicle device.

8. The method of claim 5 , further comprising:
registering information of the recognized user when the recognized user is not a previously registered user; and
storing the detected pulse information of the user in response to registering the information of the user.
