- the driver can recognize that the engine 12 has been started by vibration or sound. Therefore, in such a case, it is assumed that the start preparation is ready, the start preparation determination flag is turned on, and the output suppression control is released. Thereby, the smooth start according to a driver
- start preparation determination unit 74 may turn on the start preparation determination flag when an instruction is sent from the instruction unit 58 indicating that it is ready to start.
- the output control unit 70 controls the engine 12 so as to output a driving force in accordance with the driver's instruction to open the throttle grip 256a.

- a certain time for example, 3 seconds
- step S65 When it is determined in step S65 that the count value c is smaller than the predetermined value (a certain time has not elapsed since the throttle grip 256a was operated with the vehicle speed being substantially zero), the output control unit 70 performs output suppression control. (Step S66), and the process returns to Step S62. That is, the driving force of the engine 12 is suppressed.
- the output control unit 70 controls the driving force of the engine 12 according to the current opening degree of the throttle grip 256a. However, at the time of start after restarting the engine 12 in which the idling stop is performed, The engine 12 is controlled so that a driving force smaller than the driving force of the engine 12 corresponding to the opening of the throttle grip 256a is output.
- the output control unit 70 is configured so that the throttle valve 16 has an opening smaller than the opening corresponding to the opening of the throttle grip 256a when starting after restarting the engine 12 in which the idling stop is performed. By controlling the above, the driving force of the engine 12 is suppressed.

- the dotted line indicates the opening of the throttle valve 16 with the passage of time when the output suppression control is not performed, and the solid line indicates the opening of the throttle valve 16 with the passage of time when the output suppression control is performed. Shows the degree. In FIG. 9, it is assumed that the driver operates the throttle grip 256a so that the opening degree of the throttle grip 256a increases with time.
- the opening degree of the throttle valve 16 is gradually opened.
- the throttle valve is set so that the opening degree is smaller than when the output suppression control is not performed. 16 is controlled.
- the output suppression control changes the suppression amount (suppression amount) with the passage of time (gradually increasing the suppression amount and then gradually decreasing the suppression amount) for a certain time (for example, 3 seconds). It ends when elapses.
- step S65 determines whether the count value c is smaller than the predetermined value (the count value c is greater than or equal to the predetermined value)
- the process proceeds to step S67, and the output control unit 70 sets the count value c to 0 (counting). After resetting the value c), the process is terminated.
- the count value c is a predetermined value (a sufficient time, for example, 3 seconds or more)
- step S61 If it is determined in step S61 that the start preparation determination flag is on, the process is terminated. As a result, when the start preparation determination flag is on, the output suppression control is not performed (since it is canceled), so even when starting after restarting the engine, the smoothness according to the driver's will Start acceleration and climbing can be started.
- the output control unit 70 may immediately cancel the output suppression control.
- the idle stop is Since the driving force of the engine 12 at the start after the restart after the restart is not performed, a smooth start according to the driver's acceleration will be possible.
- the driver can recognize the restart of the engine 12 by the vibration and sound of the engine 12, and the driver can be ready to start. Therefore, in the neutral or high gear state, when the engine speed remains below the predetermined speed and the first predetermined time has elapsed, it is determined that the vehicle is ready to start, so that the smooth acceleration according to the driver's acceleration will be achieved. Start is possible.
- the driver does not start unless the gear shift operation is performed, and in the case of high gear, since the reduction ratio is small, the acceleration immediately after starting is relatively slow, so the first predetermined time is The minimum time (for example, 1 second) in which the driver can recognize the engine start can be set.

Abstract
Description
請求項7に係る発明は、請求項5に記載のエンジン制御装置であって、前記エンジンの再始動後から、アイドリング状態で、第4所定時間経過後に、再びアイドルストップを行う制御を有する、エンジン制御装置であって、前記所定時間の関係は、第1所定時間<第2所定時間<第4所定時間であることを特徴とする。
請求項7に記載の発明によれば、エンジンの再始動後から、アイドリング状態で、第4所定時間経過後に、再びアイドルストップを行う制御を有する、エンジン制御装置であって、前記所定時間の関係は、第1所定時間<第2所定時間<第4所定時間であるので、再アイドルストップ時間前に、運転者の発進用意判断を完了させ、スムーズな加速を得ることができる。
出力制御部(出力制御手段)70は、前記自動二輪車が運転者による前記スロットルの操作量に応じた走行を行うようにエンジン12を駆動制御する。出力制御部70は、運転者による前記スロットルグリップ256aの操作量(前記スロットルグリップ256aの開度)に応じて、インジェクタ18、点火プラグ20、及びドライバ24を制御する。詳しくは、前記スロットルグリップ256aの操作量に応じて、ドライバ24を制御することで、スロットルバルブ16の開度を調整するとともに、インジェクタ18によって噴射される燃料の噴射量及び噴射タイミングと点火プラグ20による点火タイミングとを制御する。これにより、エンジン回転数が運転者による前記スロットルグリップ256aの操作量に応じた回転数となる。また、前記スロットルグリップ256aの操作量が略0(前記スロットルグリップ256aの開度が略0度)のときは、出力制御部70は、エンジン回転数がアイドル回転数となるように、エンジン12を制御する。
ステップS6で、検出された車速が所定速度より小さいと判断されると、アイドルストップ制御部72は、現在のカウント値cがn(所定値)以上であるか否かを判断し(ステップS8)、カウント値cがn以上でないと判断すると、アイドルストップを行うことなく、ステップS1に戻る。ステップS8では、アイドルストップを行うための全ての停止条件が所定期間S(カウント値cがn以上)を満たしているか否かを判断している。
次いで、アイドルストップ制御部72は、アイドルストップフラグをオンにする(ステップS10)。つまり、記憶部76のアイドルストップフラグのオンオフを記憶する記憶領域に「1」を記憶させる。ここでは、アイドルストップフラグがオンのときは「1」が記憶され、オフのときは「0」が記憶されるものとする。このアイドルストップフラグのオンは、アイドルストップ制御が行われてエンジン12が停止したことを意味する。
さらにまた、出力抑制は、スロットルバイワイヤ(TBW)によるスロットル開度の制御に限らず、点火時期や燃料噴射量、スロットルボディ以外の吸気の絞り弁、排気バルブ等の制御、あるいは、これらを組み合わせることにより行うものであっても良い。
