The hybrid vehicle includes an engine; a motor capable of inputting power and a motor capable of outputting power; a power distribution and integration mechanism including a sun gear connected to the inputting motor, a carrier connected to the outputting motor, and a ring gear connected to the engine; and a transmission capable of selectively transmitting power outputted through the sun gear and a first motor shaft and power outputted through the carrier and a carrier shaft to a drive shaft with a change in speed ratio as well as having a clutch and a fixing member for non-rotatably fixing the sun gear of the power distribution and integration mechanism.

When a required speed ratio as a required value of a speed ratio between an engine and a driveshaft becomes equal to or less than a lower limit speed ratio that is not more than an n-th shift speed ratio during an n-th speed state of a transmission, a hybrid vehicle controls the engine, two motors, and the transmission to ensure output of power based on a torque demand to the driveshaft while performing an engine rotational speed adjustment of making a rotational speed of the engine equal to a shift rotational speed corresponding to an upper side shift speed ratio or an effective shift speed ratio and a shift from an n-th speed state to an (n+1)-th speed state.

A hybrid vehicle includes an engine, motors configured to input and output power, a power distribution integration mechanism, and a transmission. The power distribution integration mechanism has a sun gear connected with one of the motors, a carrier connected with the other motor, and a ring gear connected with the engine. The transmission includes a first speed change mechanism and a second speed change mechanism. The first speed change mechanism has a first speed gear train and a third speed gear train arranged to connect the carrier of the power distribution integration mechanism with a driveshaft. The second speed change mechanism has a parallel shaft-type gear train that is not used alone to set the speed ratio.

The hybrid vehicle transfers power between the two motors, releases a coupling between one of the motors and the drive shaft, adjusts the rotation speed of one of the motors which is released from the coupling to the drive shaft by the transmission so as to enable drive source element connection, and connects the clutch as well as cranks the engine by either one or the other motor when the engine is started while the clutch is released, the engine is stopped, both the motors are coupled to the drive shaft as well as at least one of the motors is caused to output power.

A motor MG1 is controlled so that the rotation speed deviation of the rotation speed of a first motor shaft 46 from the rotation speed of a second gear 62a matches a predetermined target rotation speed deviation and an actuator 92 is controlled so that a movable engaging member EM2 moves toward an engaging portion 62e for a predetermined time after the rotation speed has matched the target rotation speed deviation, if, for example, the movable engaging member EM2 is to be engaged with both of an engaging portion 46e and the engaging portion 62e of the second gear 62a to connect the first motor shaft 46 and the second gear 62a when the movable engaging member EM2 is engaged only with the engaging portion 46e of the first motor shaft 46.
摘要:
In a 2-motor drive mode with connection of both motors with a driveshaft by use of a transmission, a hybrid vehicle sets torque commands of the motors to substantially equalize an output torque of the second motor with an output torque of the first motor and to ensure output of a torque equivalent to a preset torque demand to the driveshaft. This arrangement ensures continuous output of a relatively large torque.
摘要:
When a predetermined change speed state shift condition is satisfied while the transmission connects a carrier with a drive shaft, a hybrid vehicle performs a rotational speed adjustment process of conforming a rotational speed of a motor to a target rotational speed based on a gear ratio of the transmission and a rotational speed of the drive shaft, a connection a sun gear with the drive shaft by a gear train of the transmission corresponding to a target speed, a power transfer process of transferring power between the motors in a simultaneous engagement state to make the motors output power required in a post-change speed state corresponding to a target speed, and a disconnection the carrier from the drive shaft.

摘要:
In a 2-motor drive mode with connection of both motors with a driveshaft by means of a transmission, a hybrid vehicle specifies one of the motors as a main motor of preferentially outputting power. Torque commands of the motors are then set to make the motor specified as the main motor preferentially output the power over the other motor specified as an auxiliary motor and to ensure output of a torque equivalent to a torque demand to the driveshaft.
