Abstract

 蓄電装置と、荷役装置と、油圧ポンプと、荷役用モータとを備える産業車両の制御装置が開示される。蓄電装置は、走行用モータの回生制動によって生成される回生電力を蓄電する。油圧ポンプは、荷役装置を作動させるための油圧回路に作動油を供給する。荷役用モータは油圧ポンプを駆動する。制御装置はまた、電力制御部と、抵抗流路とを備える。走行用モータの回生制動時において蓄電装置が満充電状態である場合、電力供給部は回生電力を荷役用モータに供給する制御を行なう。油圧回路に設けられた抵抗流路は、作動油に流動抵抗を付与しつつ作動油を通過させる。走行用モータの回生制動時において蓄電装置が満充電状態であり、且つ、荷役装置によって荷役作業が行われていない場合においては、油圧ポンプから供給される作動油は抵抗流路に導かれる。
