AI Technical Summary

Technical Problem

The discrepancy between the perceived and actual operating states of a seat control device in a vehicle seat can lead to incorrect operation of the vehicle, as occupants may adjust the seat position to match the apparent normal state, despite the actual state being intermediate or relaxed, preventing vehicle startup.

Method used

A seat control device with displacement and adjustment control units that manage the seat's posture transitions, ensuring the adjustment unit does not operate during intermediate states, and includes oscillation control to enhance comfort and intuitive positioning.

Benefits of technology

This configuration reduces discrepancies in perceived and actual seat states, allowing occupants to accurately adjust the seat to desired positions, ensuring vehicle operation is not hindered by misaligned seat states.

Abstract

This system suppresses discrepancies between the operating state of the seat control device as perceived by the occupant based on the appearance of the seat, and the actual operating state of the seat control device. [Solution] The seat control device 2 includes a displacement control unit 24 that displaces the seat 1 to a normal position P1 and a comfortable position P2, a displacement interruption unit 27 that interrupts the displacement of the seat 1's position by the displacement control unit 24, and an adjustment control unit 29 that adjusts the position of the seat 1 by displacing the adjustment unit 17. The seat control device 2 transitions its operating state to a normal state A1, a comfortable state A3, and an intermediate state A2 in accordance with the displacement of the seat 1's position by the displacement control unit 24. When the seat control device 2 is in the intermediate state A2, the adjustment control unit 29 does not displace the adjustment unit 17.
