PROBLEM TO BE SOLVED: To provide a slope start auxiliary device of a highly reliable vehicle which can surely operate a slope start auxiliary function even if a re-stepping operation is performed on a slope.SOLUTION: A slope start auxiliary device (33) comprises brake operation detection means (46) which detects the presence or absence of an operation of a brake pedal (29); and control means (21) which holds or releases secondary-side pressure (P2) at a brake (34) side rather than a valve of a pressure line (43) by opening and closing the valve (32) on the basis of the presence or absence of the operation of the brake pedal which is detected by the brake operation detection means. The brake operation detection means detects the presence or absence of the operation of the brake pedal on the basis of primary-side pressure (P1) at the brake pedal side rather than the valve of the pressure line.SELECTED DRAWING: Figure 2
【課題】坂道においてブレーキペダルの踏み直し操作を行っても坂道発進補助機能を確実に作動させることができる信頼性の高い車両の坂道発進補助装置を提供する。【解決手段】坂道発進補助装置(33)は、ブレーキペダル(29)の操作の有無を検出するブレーキ操作検出手段(46)と、ブレーキ操作検出手段によって検出されたブレーキペダルの操作の有無に基づいて、バルブ(32)を開閉することにより、圧力ライン(43)のバルブよりもブレーキ(34)側における二次側圧力(P2)を保持又は開放する制御手段(21)とを備え、ブレーキ操作検出手段は、圧力ラインのバルブよりもブレーキペダル側における一次側圧力(P1)に基づいて、ブレーキペダルの操作の有無を検出する。【選択図】図2
