## Abstract

A method of controlling a vehicle seat according to an example of the present disclosure includes analyzing, by a controller, input information transmitted through each switch mounted in a vehicle and classifying the input information according to an input pattern; detecting, by the controller, in which angle range among the plurality of angle ranges belongs the current angle of the seat by analyzing rotation angle information transmitted through the angle detecting sensor of the corresponding seat; controlling, by the controller, an operation of the corresponding seat by using the information of the detected angle range and the input information; and determining, by the controller, whether the operation to the corresponding seat is correct or not.

## Claims

### Claim 1

A method of controlling a vehicle seat, in a vehicle with multiple seats, comprising:
analyzing, by a controller, input information transmitted through each switch mounted in a vehicle and classifying the input information according to an input pattern;
detecting, by the controller, in which an angle range among a plurality of angle ranges belongs a current angle of the seat by analyzing rotation angle information transmitted through an angle detecting sensor of a corresponding seat;
controlling, by the controller, an operation of the corresponding seat by using the information of the detected angle range and the input information; and
determining, by the controller, whether the operation of the corresponding seat is correct or not,
wherein the input information comprises:
a first input information A1 of a seat reclining switch of a second row when the seat reclining switch of the second row is pressed forward for less than 1 second,
a second input information A2 of the seat reclining switch of the second row which the seat reclining switch of the second row is pressed rearward for less than 1 second,
a third input information A3 of the seat reclining switch of the second row which the seat reclining switch of the second row is pressed forward for more than 1 second,
a fourth input information A4 of the seat reclining switch of the second row which the seat reclining switch of the second row is pressed rearward for more than 1 second,
a first input information B1 of a seat tilt switch of the second row which the seat tilt switch of the second row is pressed upwards,
a second input information B2 of the seat tilt switch of the second row which the seat tilt switch of the second row is pressed downwards,
a first input information C1 of a seat cushion switch of the second row which the seat cushion switch is pressed in a seven-seater vehicle,
a second input information C2 of the seat cushion switch of the second row which the seat cushion switch of the second row is pressed in a five-seater vehicle,
an input information D of a second row seat back switch which a seat back switch of the second row is pressed, and
an input information E of a folding switch which the folding switch is pressed,
wherein the angle range comprises:
a first angle range I, a second angle range II and a third angle range III from a folded state of a seat back to a cushion(0°) to an angle of a reference position O, and a fourth angle range IV from the angle of the reference position O to an obtuse angle of a rear side.

### Claim 2 (depends on 1)

The method of claim 1,
wherein a performance of the operation of the corresponding seat comprises:
a forward recline operation for pulling the corresponding seat forward, a rearward recline operation for leaning the corresponding seat rearward, a tilt-up operation for increasing a front inclination angle of the corresponding seat, a tilt-down operation for lowering the front inclination angle of the corresponding seat, a walk-in operation for sliding the entire corresponding seat forward, an unwalk-in operation for sliding the corresponding seat rearward, a folding operation for completely folding a seat back of the corresponding seat into a cushion and an unfolding operation for flipping the seat back of the corresponding seat from the cushion.

### Claim 3 (depends on 1)

The method of claim 1, wherein judging, by the controller, whether the operation of the corresponding seat is correct or not is performed by using the angle information received from the angle detecting sensor of the corresponding seat.
