Abstract
A vehicle seat control apparatus for controlling seat vibration based on a sleep state of a driver and a method thereof are provided. The apparatus includes a detector that detects biometric information of a user and a driving device that controls a vibrator embedded in a vehicle seat. The apparatus further includes a controller connected with the detector and the driving device. The controller determines a sleep state of the user based on the biometric information detected by the detector, determines a frequency and a waveform of seat vibration based on the sleep state, and generates the seat vibration by controlling the driving device based on the frequency and the waveform of the seat vibration.
Claims29
A vehicle seat control apparatus, comprising:
- a detector configured to detect biometric information of a user;
- a driving device configured to control a vibrator embedded in a vehicle seat;
- and
- a controller connected with the detector and the driving device,
- wherein the controller is configured to:
- determine a sleep state of the user based on the biometric information detected by the detector, wherein the sleep state is divided into a sleep boundary stage, a sleep stage, and a deep sleep stage;
- determine a frequency and a waveform of seat vibration based on the sleep state, wherein the controller is configured to
- select the waveform of the seat vibration as a sine wave in response to determining that the sleep state is the sleep boundary stage,
- select the waveform of the seat vibration as a crossing wave in which a sine wave and a triangle wave cross with each other in response to determining that the sleep state is the sleep stage, and
- select the waveform of the seat vibration as a triangle wave in response to determining that the sleep state is the deep sleep stage;
- and
- generate the seat vibration by controlling the driving device based on the frequency and the waveform of the seat vibration.
