INTERNAL COMBUSTION ENGINE START CONTROL DEVICE FOR HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide an internal combustion engine start control device for a hybrid vehicle capable of inhibiting a troublesome change in a gear shift stage at start of an internal combustion engine.SOLUTION: In an internal combustion engine start control device for temporarily changing engine speed at start of an internal combustion engine 2 by using at least one of a power division mechanism 5 and an automatic transmission 10, a change duration when a state where the engine speed has been changed is continued at start of the internal combustion engine 2 is determined, and the necessity of the change in the engine speed by using the change of the gear shift stage of the automatic transmission 10 is determined in accordance with the operation point change amount and the change duration at start of the internal combustion engine 2.SELECTED DRAWING: Figure 1
