　The present invention is equipped with a variable timing control (VTC) mechanism which is capable of varying valve timing. An estimated value for the VTC conversion angle (VTCNFS) is calculated on the basis of the detected VTC conversion angle (VTCNOW) (S15 to S19). When converting the VTC conversion angle to the advanced side or the delayed side, the fastest response value when the VTC conversion angle with respect to the previous detected value is converted using the fastest response speed is calculated, and if the current detected valve timing value exceeds the fastest response value, the detected value (estimated value) is restricted so as not to exceed the fastest response value (S20, S21). |
