CONTROL DEVICE OF HYBRID VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a control device of a hybrid vehicle that can prolong a period of time during which the vehicle travels in a two-motor travelling mode or increase opportunities for the vehicle to travel in the mode.SOLUTION: The control device of a hybrid vehicle comprises: a power dividing mechanism connected to an engine and a motor; the other motor that applies torque to an output element of the power dividing mechanism; a brake mechanism that fastens an output shaft of the engine; a first oil pump which is driven by the engine; and a second oil pump which is electrified to be driven. In a state where a mode of travelling by output torque of the engine or a mode of travelling by output torque of the other motor is selected and when a predetermined condition is satisfied, a second oil pump is activated to start supply of oil from the second oil pump to the power dividing mechanism (steps S2 and S3).SELECTED DRAWING: Figure 1
