Abstract
A power outputting apparatus determines whether a parking gear and a parking lock pole of a parking lock mechanism are engaged. When they are engaged, a second motor outputs a torque which is the sum of a pushing torque that is slightly greater than torque pulses generated in a ring gear shaft by the torque pulses of the engine during cranking, and a reaction force torque necessary for cranking so that a first motor cranks an engine. As a result, it is possible to suppress the parking gear and the parking lock pole of the parking lock mechanism from vibrating due to the torque pulses generated during cranking of the engine, and thus also minimize the contact noise resulting therefrom.
Claims24
A power outputting apparatus capable of outputting power to a drive shaft, comprising:
- an internal combustion engine;
- a lock portion that locks the drive shaft either directly or indirectly by gear engagement;
- a startup portion that starts the internal combustion engine using a reaction force on the drive shaft;
- and
- a startup control portion which, when an instruction for startup of the internal combustion engine has been given, controls a motor to apply a torque to the lock portion greater than a torque of the reaction force generated in the drive shaft during startup of the internal combustion engine by the startup portion, and which controls the startup portion so that the internal combustion engine is started by being driven by another motor.
A control method for a power outputting apparatus which is provided with an internal combustion engine, a drive shaft and a lock portion, and which is capable of outputting power from the internal combustion engine to the drive shaft, the control method comprising the steps of:
- determining a lock state of the drive shaft;
- controlling a motor if the lock state of the locking portion is locked to apply a torque greater than a torque of a reaction force generated in the drive shaft when an instruction to start the internal combustion engine has been given;
- and
- starting the internal combustion engine being driven by another motor.
A power outputting apparatus capable of outputting power to a drive shaft, comprising:
- an internal combustion engine;
- locking means for locking the drive shaft either directly or indirectly by gear engagement;
- starting means for starting the internal combustion engine using a reaction force on the drive shaft;
- and
- startup controlling means for controlling, when an instruction for startup of the internal combustion engine has been given, controls a motor to apply a torque to the locking means greater than a torque of the reaction force generated in the drive shaft during startup of the internal combustion engine by the starting means, and controlling the starting means so that the internal combustion engine is started by being driven by another motor.
