Abstract
A control method for an internal combustion engine configured to implement fuel cut in response to becoming zero of an accelerator opening degree during travel of a vehicle, and generate an antiphase torque after the fuel cut by supplying fuel to a cylinder, in order to cancel out vibration of the vehicle caused due to the fuel cut includes setting a timing of generating the antiphase torque to be later than that for normal operation, in response to implementation of the fuel cut under high torque idle operation in which a torque of the internal combustion engine immediately before the fuel cut where the accelerator opening degree is zero is higher than that in the normal operation.
