PROBLEM TO BE SOLVED: To suppress the occurrence of a situation that an engine is recovered from a fuel cut at improper timing.SOLUTION: In an engine ECU 2, a unit change amount being a change amount of a rotation number at a preset unit crank angle is firstly calculated during the execution of a fuel cut. Also in the engine ECU 2, a torque delay angle being a timing at which a torque is succeedingly generated by an engine is estimated on the assumption that the fuel cut is finished at a current time point during the execution of the fuel cut. Then, in the engine ECU 2, an estimated engine rotation number being an engine rotation number at the torque generation timing is calculated on the basis of the unit change amount and the torque delay angle. Furthermore, in the engine ECU 2, it is determined whether or not the engine is recovered from the fuel cut by using the calculated estimated engine rotation number. |
