Description
駐車ブレーキを作動させるために、運転者が、駆動輪操作ユニットを駐車位置に変位させても、駆動輪の回転が所定回転を超えていれば、駐車ブレーキは作動状態とならない。
そのような状況においても、駐車ブレーキを作動させるには、駆動ユニットが自動的に減速制御または停止制御することで、駆動輪の回転を所定回転以下に低下させることが好ましい。このことから、本発明による走行車両では、前記位置検出器による前記駐車位置の検出時に、前記回転検出器が前記所定回転を超える回転を検出している場合、前記コントロールユニットは、前記駆動ユニットに減速指令又は停止指令を与える。
制御信号出力部62は、駐車要求に応答して、駐車信号を駐車制御ユニット6Cに出力する。駐車制御ユニット6Cは、駐車信号に応答して、駐車ブレーキ23を作動状態にする。この実施形態での駐車ON信号の入力は、左駐車ON信号と右駐車ON信号の少なくとも一方の入力を意味しているが、別実施形態として、駐車ON信号の入力は、左駐車ON信号と右駐車ON信号の両方の入力であってもよい。また、特定状態の条件に関しても、駐車ON信号を入力している状態で、左回転信号と右回転信号との両方がゼロ回転から所定回転までの間を示している場合を、特定状態としてもよい。
上記実施形態では、走行車両として芝刈機を例に挙げて説明したが、走行車両は、多目的車両や除雪車や農作業機などにも発明を適用することも可能である。
