Abstract
A hybrid vehicle includes a controller that executes catalyst warm-up control for warming up a catalyst, including first control that operates an internal combustion engine at a first operating point, and second control, after executing the first control, that operates the engine at a second operating point irrespective of driving force required to propel the vehicle. Engine output at the second point is larger than engine output at the first point. Ignition timing of the engine at the time when the first control is executed is controlled to a retarded side with respect to an ignition timing of the engine at the time when the second control is executed. When the second control is executed, at least one of a valve lift of an intake valve and a valve operating angle of the intake valve increases as charging of an electrical storage device is more limited.
