<P>PROBLEM TO BE SOLVED: To provide a hydraulic control device for a vehicle capable of controlling a calculation load and calculating modeling oil pressure to an indicated pressure accurately. <P>SOLUTION: In the hydraulic control device for a vehicle, means for calculating model hydraulic pressure 162 decides guard variation ΔPc of hydraulic pressure based on beforehand requested relation map composed of difference ΔP of indicated pressure Pin and internal pressure Pc and guard variation ΔPc of hydraulic pressure, and this model hydraulic pressure Pmdli is calculated by adding or subtracting the guard variation ΔPc of hydraulic pressure that is decided to be a model hydraulic pressure Pmdli-1 calculated last time. By doing so, a calculation result, that is not changed in detailed calculation of a model hydraulic pressure Pmdli, is obtained by solving the equation of composed flow rate or the like based on various parameters of a hydraulic actuator ACT, an accumulator ACM or the like comprising a clutch C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
