Device and method for controlling seat of vehicle

A device for controlling a vehicle seat for controlling seat vibration, the device comprising:

• a detector for detecting vehicle environment information;
• a vibration generator mounted on the vehicle seat to generate the seat vibration;
• and
• a controller electrically connected to the detector and the vibration generator,
• wherein the controller is configured to:
• detect seat environment information through the detector;
• determine a weight and a sitting posture of a user seated in the vehicle seat based on the seat environment information;
• determine a vibration pattern and a vibration excitation force based on the weight and the sitting posture of the user;
• and
• generate the seat vibration by controlling the vibration generator based on the vibration pattern and the vibration excitation force;
• wherein the detector detects a frequency-acceleration and a surface pressure for a plurality of seat portions using an accelerometer and a surface pressure sensor.
