摘要： A control system for a hybrid vehicle includes an electronic control unit. The electronic control unit is configured to, when any one of the following conditions iii) to vi) is satisfied, activate the oil pump to start supplying oil to a power split mechanism: iii) a required driving force becomes larger than or equal to a first pump changing value when a first drive mode is selected; iv) a vehicle speed becomes higher than or equal to a second pump changing value when the first drive mode is selected; v) the required driving force becomes smaller than or equal to a third pump changing value when the third drive mode is selected; and vi) the vehicle speed becomes lower than or equal to a fourth pump changing value when the third drive mode is selected.

摘要： A hybrid vehicle uses a first motor, a second motor and an engine as driving force sources and includes a gear transmission mechanism and an oil supply mechanism. The gear transmission mechanism transmits torque, output from the first motor, to a drive shaft side. The oil supply mechanism is driven by power other than power of the engine to supply oil to the gear transmission mechanism. When the hybrid vehicle is caused to travel by using the torque output from at least the first motor in a state where operation of the engine is stopped, and when an estimated amount of oil that is supplied from the oil supply mechanism to the gear transmission mechanism is smaller than or equal to a predetermined amount, an electronic control unit limits an operation state of the first motor such that load on the gear transmission mechanism decreases.
