CONTROL APPARATUS FOR A HYBRID VEHICLE DRIVE SYSTEM

摘要

A control apparatus for a hybrid vehicle drive system including: a differential device provided with rotary elements respectively connected to an engine, first and second electric motors and an output rotary member; a brake for selectively fixing the rotary element connected to the first electric motor, to a stationary member; and a parking-lock mechanism preventing a rotary motion of a parking-lock gear connected to the output rotary member, when a manually-operated shifting device is operated to a parking-lock position. The control apparatus includes an engine starting control-portion configured to start the engine in a starting-mode wherein an operating speed of the engine is raised with a torque generated by the second electric motor in an engaged state of the brake, where the engine is required to be started while the vehicle has been held at rest and the rotary motion of the parking-lock gear is prevented by the parking-lock mechanism.

1. A control apparatus for a drive system of a hybrid vehicle including: a first differential mechanism provided with a rotary element connected to an engine and a rotary element connected to a first electric motor; a second differential mechanism provided with a rotary element connected to a second electric motor and a rotary element connected to an output rotary member; a brake configured to selectively fix the rotary element of the first differential mechanism connected to the first electric motor, to a stationary member; and a parking lock mechanism configured to prevent a rotary motion of a parking lock gear connected directly or indirectly to the output rotary member, when a manually operated shifting device is operated to a parking lock position, the control apparatus comprising:
an engine starting control portion configured to start the engine in a first starting mode in which an operating speed of the engine is raised with a torque generated by the second electric motor in an engaged state of the brake, where the engine is required to be started while the vehicle has been held at rest and the rotary motion of the parking lock gear is prevented by the parking lock mechanism.
