20130225362 | HYBRID VEHICLE - In a hybrid vehicle provided with a transmission unit that allows manual gear shifting and is provided in a power transmission system that transmits power to driving wheels and an indication apparatus that is capable of providing a gear shift guide indication for prompting a manual gear shifting operation of the transmission unit, during engine start processing or during engine shutdown processing while the vehicle is traveling and/or before an engine start condition or an engine shutdown condition is established while the vehicle is traveling, the indication of the indication apparatus is provided in an indication form that is different from a gear shift guide indication for prompting a manual gear shifting operation and corresponds to the engine start processing or the engine shutdown processing. With such indication control, a situation can be eliminated in which, for example, the regular gear shift guide for prompting a manual gear shifting operation is indicated despite the fact that the effect of improving fuel consumption is unlikely to be obtained during the engine start processing, during the engine shutdown processing or the like. As a result, annoyance of the driver can be reduced. | 08-29-2013 |
20130338867 | VEHICLE AND DETERIORATION DIAGNOSIS METHOD FOR POWER STORAGE DEVICE - An ECU executes a program including the steps of: prohibiting startup of an engine when there is a request for execution of a deterioration diagnosis process and when the deterioration diagnosis process is in execution; and releasing prohibition of startup of the engine when the deterioration diagnosis process is completed. | 12-19-2013 |
20140163801 | VEHICLE, METHOD FOR CONTROLLING VEHICLE, AND CONTROL DEVICE OF VEHICLE - A vehicle includes an engine, a battery storing electric power generated by operating the engine, and an ECU allowing the engine to stop in the state where a remaining capacity of the battery is larger than a first threshold value. When the engine is started by a factor different from a reduction in the remaining capacity of the battery in the state where the remaining capacity of the battery is smaller than the first threshold value, ECU causes the engine to operate and causes the battery to be charged until the remaining capacity of the battery increases to a second threshold value which is larger than the first threshold value. | 06-12-2014 |
20140236441 | GEAR SHIFT INDICATION DEVICE - In a hybrid vehicle provided with a continuously variable electric transmission mechanism capable of sequential shift mode, a minimum engine rotational speed is specified for each gear specified in the sequential shift mode so that the lower the gear, the greater the minimum engine rotational speed. When the engine rotational speed has decreased to the minimum rotational speed while driving in the sequential shift mode, an upshift lamp of a gear shift indication device is turned on to prompt the driver to manually shift to a higher gear. As the driver shifts to a higher gear in response to the prompt, the minimum engine rotational speed is specified to a lower value. That allows for further decrease of the engine rotational speed and improves fuel consumption rate. | 08-21-2014 |
20140257653 | GEAR-SHIFT INSTRUCTION DEVICE FOR HYBRID VEHICLE - In a gear-shift instruction device for the hybrid vehicle that includes an engine that can output power for running, an electric motor (such as a motor-generator and a motor) that can output power for running, a power transmission system that transmits power to a drive wheel and can manually select a gear shift position, and a gear-shift instruction unit that prompts a change of the gear shift position to a driver, modes of the guide for gear shift are different between during electric motor running (EV running) and during hybrid running (HV running) for a same accelerator depression amount and vehicle speed in a state that allows manual gear shift operation (manual gear shift mode). This ensures the compatibility between: improvement in energy efficiency and fuel consumption by the gear shift instruction; and reduction in burden of the driver due to gear shifting based on the gear shift instruction. | 09-11-2014 |

20140148985 | CONTROL SYSTEM AND CONTROL METHOD FOR HYBRID VEHICLE - A control system for a hybrid vehicle includes a controller. When a downshift of a transmission and an increase in an amount of regeneration are carried out during regenerative coast traveling in which regeneration is carried out by an electric motor, and when a state of charge of a battery is lower than a predetermined value, the controller increases the amount of regeneration before completion of the downshift. When the state of charge of the battery is higher than or equal to the predetermined value, the controller increases the amount of regeneration after completion of the downshift. | 05-29-2014 |
20140221152 | CONTROL APPARATUS FOR HYBRID VEHICLE - Embodiments of control apparatus for hybrid vehicles are described which reduce the heat generated by a clutch and improve the response of the hybrid vehicle when an operator requests a high degree of acceleration while starting the engine and the transmission is required to perform a shift-down. In one embodiment, when the engine is required to start while the transmission is required to perform a shift-down action, the control apparatus holds a hydraulic pressure of a releasing side clutch of the transmission at a predetermined lowest stand-by value preventing a slipping action of the releasing side clutch, while a clutch K | 08-07-2014 |
20140221156 | CONTROL DEVICE AND CONTROL METHOD FOR VEHICLE - A control device for a vehicle that includes an engine, a motor, and a clutch provided in a power transmission path between the engine and the motor. The control device includes an ECU. The ECU is configured to switch travel states of the vehicle from a first to a second travel state. In the first travel state, the vehicle travels by using driving force generated by at least the engine while the clutch is engaged. In the second travel state, the vehicle travels by using driving force generated by the motor while the engine is stopped and the clutch is disengaged. The ECU is configured to maintain an operation of the engine and keep the clutch engaged after target driving force of the engine changes to a negative value when disengagement of the clutch is prohibited in switching from the first travel state to the second travel state. | 08-07-2014 |
20140222269 | CONTROL APPARATUS FOR HYBRID VEHICLE - Embodiments described herein relate to control apparatuses for hybrid vehicles which permit starting the engine and a shift-down action of the transmission while assuring not only a reduction of the heat generated by a clutch, but also an improvement in the response of the vehicle to an operator's desire for high drivability. In one embodiment, the control apparatus controls the hybrid vehicle such that when the transmission is required to be shifted down while the hybrid vehicle is switched from a motor drive mode to an engine drive mode, a time of initiation of the shift-down action of the transmission is delayed by a longer length of time when a temperature of the clutch upon initiation of an engine starting control to start the engine is relatively high than when the temperature is relatively low. Various other embodiments of control apparatuses for hybrid vehicles are also described. | 08-07-2014 |
20140222270 | CONTROL APPARATUS FOR HYBRID VEHICLE - The embodiments described herein relate to control apparatuses for hybrid vehicles which permit starting of an engine and a shift-down action of a transmission, while assuring a reduction of heat generated by a clutch and an improvement of a response of the hybrid vehicle to a vehicle operator's desire for high drivability. In one embodiment, the control apparatus controls the hybrid vehicle such that, when the transmission is required to be shifted down while the hybrid vehicle is switched from the motor drive mode to the engine drive mode, a rate of change of the input speed of said transmission is lower than when only the shift-down action is required to be performed, such that the rate of change of the input speed is relatively low when the input speed of the transmission to be established upon completion of the shift-down action is relatively high. | 08-07-2014 |

When an open failure occurs in the clutch, the second electric motor generates electricity by driving the engine and an oil amount supplied from the electric oil pump is larger than an oil amount supplied from the mechanical oil pump. | 11-19-2015 |
