20100006357 | POWER OUTPUT APPARATUS AND HYBRID VEHICLE - 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. | 01-14-2010 |
20100029436 | POWER OUTPUT APPARATUS, HYBRID VEHICLE PROVIDED WITH THE SAME, AND CONTROL METHOD OF POWER OUTPUT APPARATUS - In a hybrid vehicle, in order to stop an engine while a clutch is kept engaged and to transmit power from a motor to a drive shaft by changing a change speed state of a transmission when the power from a second motor is being transmitted to the drive shaft by the transmission, for example, a rotation speed of the first motor is adjusted so that the first motor can be connected to the drive shaft with the clutch disengaged while torque commands for both motors are set so that the power based on torque demand is outputted to the drive shaft, the power is transferred from the second motor to the first motor while both motors are connected to the drive shaft by the transmission, and the connection between the second motor and the drive shaft by the transmission is disconnected. | 02-04-2010 |

20100051361 | POWER OUTPUT APPARATUS, VEHICLE EQUIPPED WITH POWER OUTPUT APPARATUS, AND CONTROL METHOD OF POWER OUTPUT APPARATUS - In a 2-motor drive mode with connection of both motors with a driveshaft by means 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. | 03-04-2010 |
20100078238 | POWER OUTPUT APPARATUS, HYBRID VEHICLE EQUIPPED WITH POWER OUTPUT APPARATUS, AND CONTROL METHOD OF POWER OUTPUT APPARATUS - 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. | 04-01-2010 |
20100113213 | POWER OUTPUT APPARATUS, HYBRID VEHICLE HAVING THE SAME, AND METHOD OF CONTROLLING THE POWER OUTPUT APPARATUS - 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. | 05-06-2010 |
20100147610 | POWER OUTPUT APPARATUS, HYBRID VEHICLE WITH THE SAME, AND CONTROL METHOD OF POWER OUTPUT APPARATUS - 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. | 06-17-2010 |

20140174059 | VEHICLE - In a vehicle including an EHC containing a catalyst base material and an insulator insulating the EHC from the outside, an ECU estimates a temperature of the catalyst base material and a temperature of the insulator immediately after a state of the vehicle is switched from a Ready-OFF state to a Ready-ON state, as a base material temperature for determination THcpost and an insulator temperature for determination THipost, respectively. Then, when base material temperature for determination THcpost is lower than a base material threshold temperature THcth and when insulator temperature for determination THipost is lower than an insulator threshold temperature THith, the ECU allows EHC power feed, and otherwise it does not allow but prohibits EHC power feed. | 06-26-2014 |
20140290216 | VEHICULAR CONTROL DEVICE AND VEHICULAR CONTROL METHOD - In a vehicle including an engine, an electrically heatable catalyst device (EHC), and a first motor generator that generates electric power in accordance with the engine's motive power with the vehicle in a substantially stopped state with a vehicular speed lower than a threshold vehicular speed, an ECU determines, based on an amount A by which an accelerator pedal is operated and a vehicular speed V, whether a large accelerator operation has been performed with the vehicle in the substantially stopped state. If the ECU determines that the large accelerator operation has been performed with the vehicle in the substantially stopped state, the ECU activates an energization timer, and before the energization timer reaches a reference energization period of time α, the ECU energizes the EHC, and once the energization timer has reached the reference energization period of time α, the ECU ceases energizing the EHC. | 10-02-2014 |
20150057857 | VEHICLE AND CONTROL METHOD FOR VEHICLE - In a vehicle capable of performing regenerative braking by a motor, when regenerative power is supplied to both of a battery and an electric heating catalyst device (EHC), and it is predicted that the battery is overcharged at the time of turning-off of EHC (a supply of power to the EHC is stopped), ECU temporarily delays turning-off of EHC. ECU determines whether or not a condition for turning off the EHC is met during the EHC turning-off delay. When the condition for turning off the EHC is met, the regenerative brake torque is lowered so that the regenerative power becomes less than the battery acceptable power, and the hydraulic brake torque is increased depending on lowering of the regenerative brake torque, and thereafter the EHC turning-off delay is cancelled. | 02-26-2015 |
