前記マイクロコンピュータによる前記メインリレーの前記セルフシャットオフのための電源遮断動作とは別に、前記メインリレー駆動手段は、前記セルフシャットオフのための電源遮断動作が実行できない場合に前記キースイッチの遮断時点から前記第一の所定時間より長い第二の所定時間の経過後に前記メインリレーの電源遮断動作を実行するメインリレー遮断手段を備えていることを特徴とする内燃機関の制御装置。 A microcomputer that performs a process for controlling a control target of the internal combustion engine, a main relay that supplies power to the microcomputer when the power is turned on or off by a key switch, or the main relay; A main relay driving means for driving, and a communication means for transmitting and receiving control information between the microcomputer and the main relay driving means, and after the first predetermined time has elapsed since the key switch was shut off by the microcomputer. In the control device for an internal combustion engine that causes the main relay driving means to execute a power shut-off operation for self-shutoff of the main relay,
Apart from the power-off operation for the shut-off of the main relay by the microcomputer, the main relay driving means, blocking time of the key switch when the power-off operation can not be executed for the shut-off A control device for an internal combustion engine, comprising: main relay cutoff means for executing a power cutoff operation of the main relay after elapse of a second predetermined time longer than the first predetermined time.
前記第一の所定時間の経過後に実施される前記メインリレーの電源遮断動作は、前記マイクロコンピュータに設けた第一タイマの時間情報と第一所定時間設定部に設定される第一所定時間情報とを比較して得られた信号を前記通信手段を介して前記メインリレー駆動手段の前記メインリレー遮断手段に送ることで実行され、
前記第二の所定時間の経過後に実施される前記メインリレーの電源遮断動作は、前記マイクロコンピュータに設けた第二所定時間設定部に設定される第二所定時間情報を前記通信手段を介して前記リレー駆動手段に送り、この送られてきた前記第二所定時間情報と前記メインリレー駆動手段に設けた第二タイマの時間情報とを比較して得られた信号を前記リレー駆動手段の前記メインリレー遮断手段に送ることで実行されることを特徴とする内燃機関の制御装置。 The control apparatus for an internal combustion engine according to claim 1,
The power shut-off operation of the main relay performed after the first predetermined time elapses includes time information of a first timer provided in the microcomputer and first predetermined time information set in a first predetermined time setting unit. Is executed by sending the signal obtained by comparing to the main relay cutoff means of the main relay drive means through the communication means,
The power-off operation of the main relay that is performed after the elapse of the second predetermined time, the second predetermined time information set in the second predetermined time setting unit provided in the microcomputer via the communication means A signal obtained by comparing the second predetermined time information sent to the relay driving means and the time information of the second timer provided in the main relay driving means is sent to the main relay of the relay driving means. A control device for an internal combustion engine, wherein the control device is executed by being sent to a shut-off means.
前記マイクロコンピュータに入力された前記キースイッチの投入、或いは遮断状態と、前記メインリレー駆動手段に入力された前記キースイッチの投入、遮断状態とを比較し、その比較結果が異なる場合は、前記メインリレー駆動手段は前記第二の所定時間後に前記メインリレーの電源遮断動作を実行しないことを特徴とした内燃機関の制御装置。 The control apparatus for an internal combustion engine according to claim 1,
The key switch input / cut-off state input to the microcomputer is compared with the key switch input / cut-off state input to the main relay driving means. The control device for an internal combustion engine, wherein the relay drive means does not execute a power-off operation of the main relay after the second predetermined time.
前記マイクロコンピュータに入力される前記キースイッチの投入、或いは遮断状態はマイコン側キースイッチレジスタにセットされ、前記メインリレー駆動手段に入力される前記キースイッチの投入、遮断状態はメインリレー側キースイッチレジスタにセットされ、前記マイコン側キースイッチレジスタと前記メインリレー側キースイッチレジスタのセット情報の不一致から前記メインリレー側キースイッチレジスタの異常を判断し、前記メインリレー側キースイッチレジスタが断線している場合は、前記メインリレー駆動手段は前記第二の所定時間後に前記メインリレーの電源遮断動作を実行しないことを特徴とした内燃機関の制御装置。 The control apparatus for an internal combustion engine according to claim 3,
The on / off state of the key switch input to the microcomputer is set in the microcomputer side key switch register, and the on / off state of the key switch input to the main relay driving means is the main relay side key switch register. When the microcomputer-side key switch register and the main relay-side key switch register are determined to be in error from the set information mismatch, the main relay-side key switch register is disconnected. The control device for an internal combustion engine, wherein the main relay driving means does not execute a power shut-off operation of the main relay after the second predetermined time.
