PROBLEM TO BE SOLVED: To provide a controlling device capable of suppressing overshoot or undershoot in output pressure.SOLUTION: In a vehicle controlling device of the present invention, a pressure controlling device comprises a piston driven by power difference between force corresponding to pilot pressure and force corresponding to output pressure. Along with movement of the piston, the volume of a pilot room is changed. When flow rate of liquid flowing into or out from the pilot room is increased, moving distance of the piston is increased when compared to a standard as the position of the piston under an equilibrium state where the force corresponding to pilot pressure is in equilibrium with the force corresponding to the output pressure so that the flow rate of the liquid flowing into or out from an output room is increased. Controlling means, when it has been determined that gradient in output pressure should be controlled by restriction requirement determination means, performs at least one of pressure increment restriction control where a pressure reducing solenoid valve is opened during pressure increasing control or pressure reduction restriction control where a pressure increasing solenoid valve is opened during pressure reducing control. |
