PROBLEM TO BE SOLVED: To provide torque response of characteristics as demanded irrespective of transient delay of a variable valve system. SOLUTION: Static demand torque A1 and dynamic demand torque A2 are provided at a time of deceleration. Although second variable valve system target value C1 is calculated from the static demand torque, an actual value thereof delays as C2. A first variable valve system position materializing demand torque in actual value of the second variable valve system is calculated as a target value with using relating among the first, the second variable valve system positions, engine speed and torque materialized by that combination. There are two target values. The maximum torque position B3 of the first variable valve system calculated from a dynamic position C3 of the second variable valve system and static target value B1 of the first variable valve system 5 are compared to determine target value B4 of the first variable valve system with corresponding to large and small relation thereof. Consequently, torque response equivalent to the target dynamic demand torque is provided as indicated as D2. COPYRIGHT: (C)2006,JPO&NCIPI
