Abstract

　車両が停止した状態でも迅速に変速段の切換を行うことができる建設車両を提供する。本発明に係る建設車両では、制御部は、現在速度段から目標速度段へ変速段の切り替えを行う際、現在速度段に対応する現在変速段ギアと現在変速段ギアに対応する現在変速軸とが連結され、且つ、入力軸と現在変速軸との間で回転の伝達が可能である状態において、入力軸との間で回転の伝達が不能な状態にある目標変速軸と、目標速度段に対応する目標変速段ギアとを連結するプリシフトを行った後に変速段の切り替えを行う。そして、制御部は、車速検知部が検知した車速がゼロである場合には、目標変速軸と複数の変速段ギアとが非連結である状態で入力軸の回転を目標変速軸に入力するプリシフト補助制御を行った後に、プリシフトを行う。
