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 |
