摘要： PROBLEM TO BE SOLVED: To provide a technology capable of dampening vibration generated in a vehicle to the extent possible when stopping an internal combustion engine. SOLUTION: When a stopping condition of the internal combustion engine 1 has been established, the engine revolution speed NE is increased to a target engine revolution speed NEt before the engine is stopped. The target engine revolution speed NEt is calculated so that an intake pipe pressure Pi is decreased to a pressure lower than or equal to a target intake pipe pressure Pit before the engine revolution speed NE decreases to a resonant revolution speed region (S103, S104). A fuel injection volume Qf is increased by a fuel increase ΔQf required to increase the engine revolution speed NE by an engine revolution speed increase ΔNE (S105 to S107). Then, after the engine revolution speed NE has increased to the target engine revolution speed NEt, the internal combustion engine 1 is stopped with a throttle angle TA held in a fully closed position (S109).
