Description
【００２６】
また、本発明の請求項２に係る発明は、請求項１に係る発明において、上記コントローラが、上記第２判別手段で上記ロックレバー信号が出力されていた状態から出力されない状態に変化したと判断されたとき、上記エンジンの回転数を所定の低速回転数に保持するオートアイドル制御を実施させる第４処理手段と、上記所定時間の経過後の上記エンジンの停止状態で、上記第５判別手段により上記キースイッチ信号が出力されていると判別され、しかも上記第１判別手段で上記ロックレバー信号が出力されていると判別されたとき、上記第４処理手段によるオートアイドル制御を解除させて、上記第３処理手段による上記エンジン駆動信号を上記出力手段から上記エンジン制御手段に出力させる第５処理手段とを含むことを特徴としている。[0026]
Also, in the invention according to claim 2 of the present invention, in the invention according to claim 1, it is determined that the controller changes from the state where the lock lever signal is outputted by the second judging means to the state where it is not outputted. when a fourth processing means for implementing the auto idle control to maintain the rotational speed of the engine to a predetermined low speed rotation speed, at the stop state of the engine after the lapse of the predetermined time, by the fifth determining means it is determined that the key switch signal is output, deer even when it is determined that the lock lever signal is output on Symbol first discriminating means, to release the auto idle control by the fourth processing means And fifth processing means for outputting the engine drive signal from the output means to the engine control means by the third processing means.
【００５３】
なお、上記実施形態の構成に加えて、コントローラ７が、第２判別手段１６でロックレバー信号が出力されていた状態から出力されない状態に変化したと判別されたとき（図３の手順Ｓ２８）、エンジン１の回転数を当該掘削作業等に好適であった定格回転数よりもはるかに低い所定の低速回転数に保持するオートアイドル制御を実施させる第４処理手段と、上述の所定時間の経過によるエンジンの停止状態で、上述の第５判別手段２２でキースイッチ信号が出力されていると判別され（図３の手順Ｓ２２）、しかも第１判別手段５でロックレバー信号が出力されていると判別されたとき（図３の手順Ｓ２４）、第４処理手段によるオートアイドル制御を解除させて、第３処理手段２３によるエンジン駆動信号（図３の手順Ｓ２５）を出力させる第５処理手段を含む構成にしてもよい。[0053]
In addition to the configuration of the above embodiment, when it is determined that the controller 7 has changed from the state in which the lock lever signal has been output to the state in which the lock lever signal is not output (step S28 in FIG. 3). and fourth processing means for implementing the auto idle control to maintain the rotational speed of the engine 1 to a predetermined low speed rotation speed far lower than the rated rotation speed was suitable to the excavating work or the like, due to the passage of a predetermined time period described above in the stopped state of the engine, it is determined that the key switch signal in the fifth determination means 22 described above is outputted (Step S22 in FIG. 3), which is output deer also lock lever signal at a first determination unit 5 (Step S24 in FIG. 3), the auto idle control by the fourth processing means is released, and the engine drive signal (step S25 in FIG. 3) is outputted by the third processing means 23. It may be configured to include a fifth processing means that.
