Abstract
It is determined whether the current operation condition is in a transitional or steady state. If the operation condition is in a transitional state, then the transition gain is obtained by multiplying the transition base gain that is calculated corresponding to engine speed with a map by a transition degree correction coefficient. If the operation condition is in a steady state, the steady-state gain is set to the steady-state gain that is calculated corresponding to the engine speed. Subsequently, the control magnitude OCVC of the oil pressure control valve is obtained by multiplying the difference between the target advance angle and the actual advance angle by the gain.
