<P>PROBLEM TO BE SOLVED: To provide a variable valve control device in a hybrid vehicle, which suppresses racing of engine speed with excellent responsiveness while controlling to intake valve closing timing required when an engine is started. <P>SOLUTION: Immediately before the engine is stopped according to a stop demand, the intake valve closing timing IVC is advanced to the retard angle of a bottom dead center BDC in order to stabilize an engine stop position. When the engine is stopped, the intake valve closing timing IVC is retarded to first closing timing IVC1 suitable for starting (for example, 80 degrees after the ABDC). The engine is started with the closing timing IVC set to the first closing timing IVC1, and the intake valve closing timing IVC is changed to a retard side relative to the first closing timing IVC1 with respect to the racing of the engine speed NE immediately after start-up completion. <P>COPYRIGHT: (C)2011,JPO&INPIT |
