First, referring to (a) of FIG. 9, the controller 190 has a relatively large rear pressure value transmitted from the rear pressure sensor 126 and a front pressure value transmitted from the front pressure sensor 127 is relatively small, When the difference between the rear pressure value and the front pressure value exceeds the reference value, it is determined that the height of the seat seating portion 70 does not match the height of the occupant, so that it is impossible to sit in a correct posture. Thereafter, the controller 190 controls the rear air pump 136 to introduce air into the rear air cell 116, and the front air pump 137 controls the air to flow into the front air cell 117, but the rear air cell 116 ) And the amount of air introduced into the front air cell 117 is controlled to be the same, so that the overall height of the seat seat 70 is increased than before.

Next, referring to (b) of FIG. 9, the control unit 190 has a relatively large rear pressure value transmitted from the rear pressure sensor 126 and a relatively small front pressure value transmitted from the front pressure sensor 127, When the difference between the rear pressure value and the front pressure value exceeds the reference value, it is determined that the angle of the seat seating portion 70 does not match the height of the occupant, so that it is impossible to sit in a correct posture. Thereafter, the control unit 190 controls the rear air pump 136 to introduce air into the rear air cell 116, and the front air pump 137 controls the air to flow into the front air cell 117, but the front air cell 117 ) Is controlled so that the amount of air introduced into the rear air cell 116 is greater than the amount of air introduced into the rear air cell 116, so that the top angle of the seat seating portion 70 is greater than the conventional one. At this time, the cross section of the front air cell 117 is formed in a trapezoidal shape and the cross section of the rear air cell 116 is formed in a triangular shape, so that a step is not generated between the upper side of the front air cell 117 and the upper side of the rear air cell 116 This is desirable.

Next, referring to FIG. 10, the controller 190 has a relatively large rear pressure value transmitted from the rear pressure sensor 126 and a front pressure value transmitted from the front pressure sensor 127 is relatively small, and the rear pressure value and When the difference between the front pressure values exceeds the reference value, it is determined that the length of the seat seating portion 70 does not match the height of the occupant, so that it is impossible to sit in the correct posture. Thereafter, the control unit 190 controls the extension air pump 138 to introduce air into the extension air cell 118 so that the length of the seat seat 70 in the front and rear direction is longer than before.

As such, when the knee is positioned higher than the pelvis, this pressure distribution appears. In this posture, it can be seen that the height or angle of the seat seat 70 does not match the height of the occupant, and the waist cannot be a correct posture. Accordingly, by introducing air into the seating air member 115 provided in the seat seating portion 70, the inclination angle of the seat seating portion 70 or the length of the seat seating portion 70 or the overall height of the seat seating portion 70 By adjusting the, the load applied to the seat seat 70 is dispersed so that it is not concentrated to either side.

Then, as shown in FIG. 12, there is no difference between the pressure distribution 126a measured by the rear pressure sensor 126 and the pressure distribution 127a measured by the front pressure sensor 127, so that the seat mounting portion ( 70) is distributed so that the pressure of the occupant is not concentrated on either side, so that the seat seat 70 comfortably supports the hip and thigh of the occupant, and enables comfortable long-distance driving through correcting the driving posture. It works.

In the determination process, if the gear position is located at P (Parking) while the engine is started, it is determined as a stop mode. As a result of the determination, in the case of the stop mode, the control unit 190 determines whether to proceed with the posture correction mode through an on/off signal input from the input unit 140 (S110). The input unit 140 may be composed of a touch system or an electronic switch or a mechanical switch or a command received from a smart phone provided in AVN (Audio Video Navigation) or USM (User Setting Mode). As a result of the determination, when the posture correction mode is turned on, the control unit 190 transmits from the back sensor member 120 and the seating sensor member 125 to the seat back portion 60 and the seat seating portion 70 of the seat 50. It receives pressure. At this time, the occupant sits comfortably in the usual sitting position for accurate measurement. Thereafter, the control unit 190 receives a pressure value from the backrest sensor member 120 and the seating sensor member 125 (S120).

Thereafter, when the posture correction is required, that is, the pressure value transmitted from the backrest sensor member 120 exceeds the reference value, or the difference between the rear pressure value and the front pressure value transmitted from the seating sensor member 125 When is exceeding the reference value (S130), by controlling the backrest pump member 130 or the seating pump member 135, so that the backrest air member 110 or the seating air member 115 is inflated or contracted, the pressure of the waist Disperse so that it is not concentrated to either side (S140). Subsequently, the control unit 190 performs step S120 again, and checks once more whether the pressure of the lower back has not shifted to either side.

Referring to FIGS. 2 to 12 and 14, in the method for adjusting a human body-sensitive seat according to a second preferred embodiment of the present invention, first, the control unit 190 determines whether or not the current driving mode is in a driving mode from the mode detection unit 150. Do (S200). In the determination process, if the vehicle speed is currently 1 km/h or more using the vehicle speed, it is determined that the vehicle is running. As a result of the determination, in the case of the driving mode, the controller 190 determines whether to proceed with the posture correction mode through an on/off signal input from the input unit 140 (S210). As a result of the determination, when the posture correction mode is turned on, the control unit 190 transmits from the back sensor member 120 and the seating sensor member 125 to the seat back portion 60 and the seat seating portion 70 of the seat 50. It receives pressure. At this time, the occupant sits comfortably in the usual sitting position for accurate measurement. Thereafter, the control unit 190 receives a pressure value from the backrest sensor member 120 and the seating sensor member 125 (S220).

Thereafter, when the posture correction is required, that is, the pressure value transmitted from the backrest sensor member 120 exceeds the reference value, or the difference between the rear pressure value and the front pressure value transmitted from the seating sensor member 125 When is exceeding the reference value (S230), by controlling the backrest pump member 130 or the seating pump member 135, so that the backrest air member 110 or the seating air member 115 is inflated or contracted, so that the pressure of the waist Disperse so that it is not concentrated to either side (S240). Subsequently, the control unit 190 determines whether the current driving time has exceeded a preset allowable time through the driving time transmitted from the driving time detecting unit 160 (S250). As a result of the determination, when the driving time transmitted from the driving time detecting unit 160 exceeds a preset allowable time, the display unit 180 controls to display the guide text to the outside (S260). In the case of a guide, it is a stretching time or a break that is proportional to the driving time, for example, "A 10-minute break is required." It can be composed of characters such as

As such, the present invention informs the outside when a driver needs to stretch or rest due to a long drive, and induces the driver to take a stretch or rest by lifting a rest area or a drowsy shelter, thereby minimizing the back burden caused by long driving, It has the effect of preventing drowsy driving in advance.

Although the present invention has been described in detail in the above embodiments, it is natural that the present invention is not limited thereto, and it is obvious to those skilled in the art that various modifications and modifications are possible within the scope of the technical idea of the present invention, and such modifications and modifications are attached. If it falls within the scope of the claims, the technical idea should also be regarded as belonging to the present invention.
