Abstract
When an incremental amount of a steering angle exceeds a reference incremental amount, an ECUexecutes vehicle attitude control of reducing an output torque of an engine, and, in a given operating range, drives a spark plugin a manner allowing an air-fuel mixture to be self-ignited at a given timing, thereby executing SPCCI combustion. When there is a request for an additional deceleration from the vehicle attitude control (#: YES), and the SPCCI combustion is performed (#: YES), the ECUexecutes fuel amount reduction control of reducing the amount of fuel to be supplied into a cylinder(#), so as to attain torque reduction for the vehicle attitude control. On the other hand, when the SPCCI combustion is not performed (#: NO), the ECUexecutes ignition retardation control of retarding an ignition timing of the spark plug(#).
