System and control method for preventing interference between front and rear seats for vehicle
First Claim
1. A system for preventing interference between front and rear seats for a vehicle, which is configured to enable at least the front seat to recline and slide, the system comprising:
- a reclining unit which adjusts a seat back angle of the front seat;
a slide unit which adjusts forward and rearward slide positions of the front seat;
a rear scat position detecting unit which detects a rear seat position; and
a control unit which controls operations of the reclining unit and the slide unit,wherein the control unit receives the rear seat position from the rear seat position detecting unit, and performs rearward reclining control and rearward slide control within a range in which a seat back of the front seat does not cause interference with the rear seat recognized based on the rear seat position,wherein the control unit matches and sets in advance a seat back limit angle of the front seat with respect to an interval between the front and rear seats indicated by a predetermined unit, and performs the rearward reclining control within the seat back limit angle, which is matched with respect to the front seat position detected by the slide unit and the interval between the front and rear seats calculated by the rear seat position detecting unit, at the time of the rearward reclining control,wherein the unit matches and sets in advance a limit interval between the front and rear seats which corresponds to the seat back angle of the front seat indicated by a predetermined unit, and performs the rearwards slide control within the limit interval between the front and rear seats, which is matched with respect to the seat back angle detected by the reclining unit, at the time of the rearward slide control, andwherein the slide unit includes;
a slide motor which adjusts the front seat position; and
a slide position sensor which detects the front seat position and transmits the front seat position to the control unit.

Abstract
A system and a control method can prevent interference between front and rear seats for a vehicle, and allow reclining control and slide control for the front and rear seats to be performed, to control a seat back rearward movement angle of a front seat based on a seat back angle of the front seat, a position of the rear seat, and an interval between the front and rear seats at the time of rearward reclining control for the front seat, control a rearward slide movement distance based on the seat back angle of the front seat at the time of rearward slide control for the front seat, and calculate in advance a likelihood that interference will occur between the front and rear seats so as to stop the control operation at the time of performing a rearward reclining control operation and a rearward slide control operation.

5. A control method for preventing interference between front and rear seats for a vehicle, which is configured to enable at least the front seat to recline and slide, the control method comprising:
-
inputting, by a control unit, a reclining control operation of the front seat from a driver; determining, by the control unit, whether the reclining control operation is rearward reclining control; calculating, by the control unit, an interval between the front and rear seats by detecting a front seat position and a rear seat position when the rearward reclining control is inputted; detecting, by the control unit, a seat back angle of the front seat; performing, by the control unit, the rearward reclining control within a range in which a seat back of the front seat does not cause interference with the rear seat at an interval between the front and rear seats which is calculated from the detected front seat position and the detected rear seat position; inputting, by control unit, a slide control operation of the front seat from the driven; determining, by the control unit, whether the slide control operation is rearward slide control; calculating, by the control unit an interval between the front and rear seats by detecting the front seat position and the rear scat position when the rearward slide control is inputted; detecting, by the control unit, a scat back angle of the front seat; and performing, by the control unit, the rearward slide control within a range in which the front seat position does not cause interference with the rear seat at the detected seat back angle of the front seat. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:
-
program instructions that input a reclining control operation of a front seat from a driver; program instructions that determine whether the reclining control operation is rearward reclining control; program instructions that calculate an interval between the front seat and a rear set by detecting a front seat position and a rear seat position When the rearward reclining control is inputted; program instructions that detect a seat back angle of the front seat; program instructions that perform the rearward reclining control within a range in which a seat back of the front seat does not cause interference with the rear seat at an interval between the front and rear seats which is calculated from the detected front seat position and the detected rear seat position; program instructions that input a slide control operation o the front seat rom the driver; program instructions that determine whether the slide control operation is rearward slide control; program instructions that calculate an interval between the front and rear seats by detecting the front seat position and the rear seat position When the rearward slide control is inputted; program instructions that detect a seat back angle of the front seat; and program instructions that perform the rearward slide control within a range in which the front seat position does not cause interference with the rear seat at the detected seat back angle of the front seat.
