Document Type and Number:
Japanese Patent JP2015116967
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To inhibit starting of an internal combustion engine from making a user uncomfortable and improve fuel economy even while at least one of a lift amount and a working angle of an intake valve that is controlled by a variable valve train is fixed.SOLUTION: An engine includes a variable valve gear for changing operation characteristics of an intake valve. Even when the operation characteristics are fixed while a lift amount and/or a working angle of the intake valve controlled by the variable valve gear is smaller than a predetermined value (Yes in S120), an intermittent operation of the engine is not stopped uniformly. When a vehicle is not in a state where uncomfortable feeling of a user caused by a shock at start of the engine increases (engine starting shock deteriorating state) (No is determined in S130), intermittent stop of the engine is allowed.
