Preferably, the road condition determination unit includes a gyro sensor for detecting a tilt of the driving vehicle, and a navigation storing a map including road slope information and curved road information.

The driver condition monitoring unit includes a camera, and the seat position control signal is a signal that can be independently controlled in left, right, up, and down directions with respect to the driver seat.

According to the present invention having such a configuration, the front field of view is properly secured due to the optimum seat position control according to the driver's eye position and body shape at the time of entering / exiting the slope.

The driver's convenience is improved by securing the view when entering / exiting the slope.

Riding comfort is improved by seat control when the driver's posture is caused by the vehicle's tilt when driving on a curve.

The road state determination unit 10 determines road inclination, entrance and exit (out and coming in) of the inclination road of the traveling vehicle, and entrance and exit by a curve. The road condition determination unit 10 detects the inclination of the vehicle using the gyro sensor 12 installed in the vehicle, and determines the vehicle tilt by the road inclination and the curve based on the detected information. The road condition determination unit 10 determines whether the road is inclined or curved using the navigation 14 storing the advanced driver assistance system (ADAS) map including road ramp information and curved road information.

The driver condition monitoring unit 20 detects the driver's eyes and determines the driver's sitting height and driver's position based on the eye position information. Although not shown, the driver condition monitoring unit 20 includes a camera. In more detail, the driver condition monitoring unit 20 detects the driver's face and eyes with a camera (not shown) and determines a sitting height, a driver's posture, and a body shape based on eye position information. On the other hand, the driver state monitoring unit 20 determines the driver's posture pointed at the time of driving in a curve.

The seat optimal position analysis unit 30 analyzes the seat position corresponding to the eye position and body shape of the driver based on the information from the road state determination unit 10 and the driver state monitoring unit 20. That is, the seat optimal position analysis unit 30 derives the optimal position of the seat to secure the viewing angle in a range where the driver does not feel discomfort based on the eye position. In addition, the seat optimum position analysis unit 30 derives the optimal position of the seat which prevents the driver's posture from moving in a curve.

The sheet position controller 40 generates a sheet position control signal based on the information from the sheet optimum position analyzer 30 and provides the generated sheet position control signal to the sheet driver 50. That is, the seat position control part 40 outputs the controlled seat position control signal which can ensure a viewing angle before entering and exiting a ramp. In addition, the seat position control unit 40 outputs an optimal seat position control signal that can prevent the vehicle from tipping and the driver's posture during driving in a curved line. Here, the seat position control signal is a signal that can be independently controlled in the left, right, up, and down directions with respect to the driver's seat. Conventionally, only the up / down direction of the front / rear side can be controlled with respect to the driver's seat, but in the embodiment of the present invention, independent control is performed in the left / right side of the up and down direction.

The seat driver 50 independently drives the driver seat 60 in the left / right up and down directions according to the seat position control signal from the seat position control unit 40. The seat driving unit 50 returns to the original seat position when escaping the ramp, the curved path, or the like.

Next, the operation of the driver's seat automatic adjustment device according to an embodiment of the present invention will be described.

First, when the vehicle is driven, the road condition determination unit 10 detects the inclination of the vehicle using the gyro sensor 12 and determines the vehicle tilt by the road inclination and the curve based on the detected information. In addition, the road state determination unit 10 determines whether the road is inclined and curved by using the navigation 14 storing the ADAS map.

In addition, the driver condition monitoring unit 20 detects the driver's face and eyes with a camera (not shown) and determines a sitting key, driver's posture, and body type based on eye position information. In addition, the driver state monitoring unit 20 determines the driver's posture pointed position when driving in a curve.

The road state determination unit 10 and the driver state monitoring unit 20 transmit the determined information to the seat optimum position analysis unit 30.

Accordingly, the seat optimal position analysis unit 30 analyzes the seat position corresponding to the driver's eye position and body shape based on the information from the road condition determination unit 10 and the driver state monitoring unit 20, and analyzes the result. Transfer to the sheet position control unit 40.

The seat position control unit 40 controls, based on the information from the sheet optimum position analysis unit 30, a controlled seat position control signal and curve path that can secure a viewing angle before entering and exiting the ramp, for example. It generates the optimal seat position control signal to prevent the vehicle from tipping and the driver's posture during driving.

The sheet position control signal generated by the sheet position controller 40 is provided to the sheet driver 50. The seat driver 50 independently drives the driver seat 60 in the left / right up and down directions according to the seat position control signal from the seat position control unit 40. In this case, the same effects as in FIGS. 2 and 3 will be obtained.

Finally, when the vehicle escapes the ramp or curve, the current driver seat 60 position is returned to the original seat position. Here, it can be sufficiently understood by the information from the road condition determining unit 10 and the driver condition monitoring unit 20 that the vehicle has escaped the slope or the curved road.
