Description
しかしながら、特許文献１に記載の充電制御装置のように、充電電流が規定値を超えないように電圧変換部の出力電圧を制御するだけでは、充電電流が規定値以下である限り電圧変換部の出力電圧が上昇し続けてしまう。 However, as in the charging control device described in Patent Document 1, simply controlling the output voltage of the voltage conversion unit so that the charging current does not exceed the specified value is sufficient for the voltage conversion unit as long as the charging current is equal to or less than the specified value . The output voltage keeps rising .
また、制御部１２は、スタータ３によりエンジン２が始動後最初の充電電流低減制御が実行される前であり、かつ充電電流Ｉが所定電流Ｉ１未満であること、または、エンジン２が始動後最初の充電電流低減制御が実行された後であり、かつ充電電流Ｉが所定電流Ｉ１より大きい所定電流Ｉ３未満であること、の何れかを実施条件として、充電電流低減制御の実施条件が満たされてから所定時間Ｔ１が経過するまでの間、充電電流低減制御を実施するようになっている。所定電流Ｉ３は本発明における第３所定電流に対応する。 Further, in the control unit 12, the charging current I is less than the predetermined current I1 before the first charge current reduction control is executed after the engine 2 is started by the starter 3, or the engine 2 is first started. The execution condition of the charge current reduction control is satisfied, provided that the charge current reduction control of the above is executed and the charge current I is larger than the predetermined current I1 and less than the predetermined current I3. The charging current reduction control is performed from the time until the predetermined time T1 elapses. The predetermined current I3 corresponds to the third predetermined current in the present invention.
また、上述の実施例では、車両１は、エンジン２と、サブバッテリ６から電力が供給されることでエンジン２を始動させるスタータとを備えている。そして、制御部１２は、スタータ３によりエンジン２が始動後最初の充電電流低減制御が実行される前であり、かつ充電電流Ｉが所定電流Ｉ１未満であること、または、エンジン２が始動後最初の充電電流低減制御が実行された後であり、かつ充電電流Ｉが所定電流Ｉ１より大きい所定電流Ｉ３未満であること、の何れかを実施条件として、充電電流低減制御の実施条件が満たされてから所定時間Ｔ２が経過するまでの間、充電電流低減制御を実施する。 Further, in the above-described embodiment, the vehicle 1 includes an engine 2 and a starter that starts the engine 2 by supplying electric power from the sub-battery 6. Then, the control unit 12 determines that the charging current I is less than the predetermined current I1 before the first charging current reduction control is executed after the engine 2 is started by the starter 3, or that the engine 2 is first started. The execution condition of the charge current reduction control is satisfied, provided that the charge current reduction control of the above is executed and the charge current I is larger than the predetermined current I1 and less than the predetermined current I3. The charging current reduction control is performed from the time until the predetermined time T2 elapses.
なお、上述の実施例では、ステップＳ１において、充電電流ＩがＩ１未満であることを満たすか否かを判定条件の１つとしたが、この判定条件の代わりに充電電流ＩがＩ１未満でありかつＩ２以上であるか、または充電電流低減制御を実行中であるかのいずれかを満たすか否かを判定条件として用いても良い。この構成によれば、スタータによるＥＮＧ始動から所定時間Ｔ１経過しており、かつ、フラグｆ＝０である場合に、かつ充電電流Ｉが下降してＩ１未満となると充電電流低減制御を開始することができる。さらに、充電電流低減制御が既に実行されている場合は、充電電流ＩがＩ２未満であってもステップＳ１がＹＥＳとなるため、充電電流低減制御を継続することが可能になる。 In the above embodiment, one of the determination conditions is whether or not the charging current I is less than I1 in step S1, but instead of this determination condition, the charging current I is less than I1. Whether or not I2 or more is satisfied or whether the charging current reduction control is being executed may be used as a determination condition. According to this configuration, when a predetermined time T1 has elapsed from the ENG start by the starter and the flag f = 0, and the charging current I drops to less than I1, the charging current reduction control is started. Can be done. Further, when the charging current reduction control has already been executed, step S1 is YES even if the charging current I is less than I2, so that the charging current reduction control can be continued.
また、上述の実施例では、ステップＳ８において、充電電流ＩがＩ３未満であることを満たすか否かを判定条件の一つとしたが、この判定条件の代わりに充電電流ＩがＩ３未満でありかつＩ２以上であるか、または充電電流低減制御を実行中であるかのいずれかを満たすか否かを判定条件として用いても良い。この構成によれば、タイマＴｂがＴ３以上であり、かつフラグｆ＝１である場合に、充電電流Ｉが下降してＩ３未満となると充電電流低減制御を開始することができる。さらに、充電電流低減制御が既に実行されている場合は、充電電流ＩがＩ２未満であってもステップＳ８がＹＥＳとなるため、充電電流低減制御を継続することが可能になる。 Further, in the above-described embodiment, in step S8, whether or not the charging current I is less than I3 is satisfied as one of the determination conditions, but instead of this determination condition, the charging current I is less than I3. Whether or not it satisfies either I2 or more or charging current reduction control is being executed may be used as a determination condition. According to this configuration, when the timer Tb is T3 or more and the flag f = 1, the charging current reduction control can be started when the charging current I drops to less than I3. Further, when the charging current reduction control has already been executed, step S8 is YES even if the charging current I is less than I2, so that the charging current reduction control can be continued.
