Description

本発明は、1つのモータの正転又は逆転により、車両用シートの前後位置と車両用シートの前後における上下位置と背もたれの角度の合計8つの動作を行うモータの制御に関するものである。 The present invention relates to control of a motor that performs a total of eight operations of a front and rear position of a vehicle seat, a vertical position and a backrest angle of the front and rear of a vehicle seat, by forward or reverse rotation of one motor.

従来、車両用シートに使用されるモータとして、例えば、特許文献1に記載する「パワーシート調節装置」が提案されている。   Conventionally, as a motor used for a vehicle seat, for example, a “power seat adjusting device” described in Patent Document 1 has been proposed.

この特許文献1のパワーシート調節装置では、シートの前後位置を調節するスライド機構と、シートの前方側上下位置を調節する前方側上下機構と、シートの後方側上下位置を調節する後方側上下機構と、シートの背もたれ角度を調節するリクライニング装置と、正逆両方向に回転可能な単一モータを備え、それぞれ独立に又は複数の気候を同時に作動可能に構成されている。   In the power seat adjusting device disclosed in Patent Document 1, a slide mechanism that adjusts the front-rear position of the seat, a front-side vertical mechanism that adjusts the front-side vertical position of the seat, and a rear-side vertical mechanism that adjusts the rear-side vertical position of the seat And a reclining device that adjusts the backrest angle of the seat and a single motor that can rotate in both forward and reverse directions, each of which can be operated independently or simultaneously in a plurality of climates.

特開平08−188073号Japanese Patent Laid-Open No. 08-188073

しかし、上記に示す構造では、1つのモータで複数の機構を動かす場合において、モータの回転方向と各機構の動作方向が一致していなければ、複数の機構を同時に動かすことができない構造となっている。そのため、モータの回転方向と動作方向が一致する機構を検出する回転検出器を設けなければならない。この回転検出器は、パルス信号によりモータの回転方向と動作方向が一致する機構を検出するものであり、シートポジションを変更する度に、モータの回転方向と動作方向が一致する機構を検出する必要があるため、シートポジションを変更する際に時間を要していた。   However, in the structure shown above, when a plurality of mechanisms are moved by one motor, the plurality of mechanisms cannot be moved at the same time unless the rotation direction of the motor and the operation direction of each mechanism coincide. Yes. Therefore, a rotation detector that detects a mechanism in which the rotation direction of the motor matches the operation direction must be provided. This rotation detector detects a mechanism in which the rotation direction of the motor coincides with the operation direction based on a pulse signal, and it is necessary to detect a mechanism in which the rotation direction of the motor coincides with the operation direction every time the sheet position is changed. Because of this, it took time to change the seat position.

そこで、本発明は上記に示す課題を解決するためになされたものであり、複数の機構を1つのモータで動かすモータ装置において、所望シート位置への再生時間を短縮することを目的とする。   Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to shorten the reproduction time to a desired sheet position in a motor device that moves a plurality of mechanisms with a single motor.

上記に示す課題を解決するために本発明のモータ装置は、車両用シートのスライド機構と前方上下機構及び後方上下機構とリクライニング機構を動作するモータと、このモータの駆動を制御するシートECUとで構成されており、シートECUにメモリを設けることで、車両用シートの現在位置及び現在位置の1つ前の位置を記憶し比較を行い、各機構の動作方向を検出しモータの回転方向と一致する機構を動作させることを技術的特徴とする。 In order to solve the above-described problems, a motor device according to the present invention includes a vehicle seat slide mechanism, a front vertical mechanism, a rear vertical mechanism, and a reclining mechanism, and a seat ECU that controls driving of the motor. It is configured, and by providing a memory in the seat ECU, the current position of the vehicle seat and the position immediately before the current position are stored and compared, and the operation direction of each mechanism is detected and coincides with the rotation direction of the motor The technical feature is to operate the mechanism.

請求項1記載のモータ装置によれば、モータの回転方向と各機構の動作方向が一致する機構を短時間で検出でき、モータの回転方向と一致する機構を同時に動作させることが可能となるため、所望のシート位置への再生時間を短縮することができる。   According to the motor device of the first aspect, a mechanism in which the rotation direction of the motor and the operation direction of each mechanism coincide can be detected in a short time, and the mechanisms that coincide with the rotation direction of the motor can be operated simultaneously. The reproduction time to a desired sheet position can be shortened.

First, the configuration of the vehicle seat 20 will be described with reference to FIG.
As shown in FIG. 1, the vehicle seat 20 adjusts the vertical position in front of the seat, and a slide mechanism 21 that adjusts the front and rear position of the seat, which includes a seat cushion on which the occupant is seated and a seat back that is the back of the occupant. Front vertical mechanism 22, rear vertical mechanism 23 that adjusts the vertical position of the rear of the seat, reclining mechanism 24 that adjusts the angle of the back of the seat, and a mechanism for operating each mechanism to instruct a change in seat position A switch 25 is provided. Here, each mechanism can move the vehicle seat 20 back and forth, move the vehicle seat 20 forward and backward up and down, and change the reclining angle by driving a motor 11 described later. Is possible.

次に、本発明のモータ装置10について説明する。
モータ装置10は、図2に示すように、車両用シート20のスライド機構21と前方上下機構22及び後方上下機構23とリクライニング機構24の各機構を動作するモータ11と、このモータ11の駆動の制御を行うシートECU12で構成される。
Next, the motor device 10 of the present invention will be described.
As shown in FIG. 2, the motor device 10 includes a motor 11 that operates a slide mechanism 21 of the vehicle seat 20, a front vertical mechanism 22, a rear vertical mechanism 23, and a reclining mechanism 24, and driving of the motor 11. It is comprised by seat ECU12 which performs control.

モータ11は、図2に示すように、車両用シート20のシートクッション又はシートバックに設けられ、車両用シート20に備えるスイッチ25が操作されることによって正転、停止、逆転を行い、各機構を動作する。また、モータ11の回転方向と各機構の動作方向が一致するものがあれば、複数の機構を同時に動作することが可能な構造とする。   As shown in FIG. 2, the motor 11 is provided on the seat cushion or the seat back of the vehicle seat 20, and performs forward rotation, stop, and reverse rotation by operating a switch 25 provided in the vehicle seat 20. Work. Further, if there is one in which the rotation direction of the motor 11 and the operation direction of each mechanism coincide, a structure in which a plurality of mechanisms can be operated simultaneously is adopted.

シートECU12は、車両用シート20のシートポジションの変更を指示するスイッチ25を操作することによって生じるシート作動指令信号に基づいて、モータ11の駆動を制御するものであって、シートポジションの変更を指示するスイッチ25の回路に組み込まれる。また、このシートECU12は、各機構の現在位置及び現在位置の1つ前の位置(以下、記憶位置)を記憶するメモリ13が設けられる。このメモリ13は、図3に示すように、各機構の現在位置及び記憶位置を記憶することで、モータ11の回転方向と一致する各機構の動作方向を検出することが可能となる。   The seat ECU 12 controls the driving of the motor 11 on the basis of a seat actuation command signal generated by operating a switch 25 for instructing a change of the seat position of the vehicle seat 20, and instructs the change of the seat position. The switch 25 is incorporated in the circuit. In addition, the seat ECU 12 is provided with a memory 13 that stores the current position of each mechanism and the position immediately before the current position (hereinafter, storage position). As shown in FIG. 3, the memory 13 stores the current position and storage position of each mechanism, so that the operation direction of each mechanism that matches the rotation direction of the motor 11 can be detected.

続いて、本実施例に係るモータ装置10の動作について図3及び図4を参照し説明する。
車両用シート20は、車両のエンジンがかかると同時にシートECU12により現在のスライド位置と前方上下位置と後方上下位置とリクライニング角度をそれぞれ記憶する。
Next, the operation of the motor device 10 according to this embodiment will be described with reference to FIGS.
The vehicle seat 20 stores the current slide position, front vertical position, rear vertical position, and reclining angle by the seat ECU 12 at the same time as the vehicle engine is started.

乗員が車両用シート20に着座しスイッチ25の操作を行うことにより車両用シート20は、シートポジションを変更する。ここで、乗員が車両用シート20のスイッチ25を操作することで、モータ11の回転方向が決定し、シートECU12に情報が伝達する。 When the occupant sits on the vehicle seat 20 and operates the switch 25, the vehicle seat 20 changes the seat position. Here, when the occupant operates the switch 25 of the vehicle seat 20, the rotation direction of the motor 11 is determined, and information is transmitted to the seat ECU 12.

モータ11の回転方向を検出したシートECU12は、各機構の動作方向を検出するためメモリ13からエンジン始動時に記憶した記憶位置を呼び出して、モータ11の回転方向と一致する機構の比較を行い、各機構の動作方向の検出を行う。ここで、各機構の動作方向を検出したシートECU12は、モータ11の回転方向と一致する複数の機構を同時に動作して車両用シート20を所望のシート位置へ移動させることにより車両用シート20の再生時間を短縮することができる。   The seat ECU 12 that detects the rotation direction of the motor 11 calls the storage position stored at the time of engine start from the memory 13 in order to detect the operation direction of each mechanism, and compares the mechanism that matches the rotation direction of the motor 11. The direction of movement of the mechanism is detected. Here, the seat ECU 12 that has detected the operation direction of each mechanism simultaneously operates a plurality of mechanisms that coincide with the rotation direction of the motor 11 to move the vehicle seat 20 to a desired seat position. Playback time can be shortened.
