Abstract
With an engine wherein the setting of a target air-fuel ratio is changed in accordance with operating conditions, and the air-fuel ratio of the engine intake mixture is controlled in accordance with the target air-fuel ratio, a gear ratio in an automatic continuously variable transmission fitted to the engine is forcibly changed towards a ratio which suppresses changes in vehicle drive torque, at the time of changing the setting of the target air-fuel ratio. As a result even with a rapid change in engine output torque following a change in the target air-fuel ratio, a rapid change in the vehicle drive torque can be suppressed, so that vehicle driving stability can be improved.
