Abstract: In the present specification, degradation of a battery is suppressed in a hybrid vehicle having an EV mode in which the hybrid vehicle runs without using an engine and an HV mode in which the hybrid vehicle runs using both the engine and a motor. A controller of the hybrid vehicle is configured to limit a usage range of the battery in the EV mode with an execution request of the EV mode having been made by an information input from outside to the vehicle than in the EV mode with no execution request. The degradation of the battery is suppressed by limiting the usage range of the battery.

Abstract: A hybrid vehicle for reducing a variation in accelerator position when an EV mode is switched to a HV mode is provided. A controller executes the following process during running in the EV mode. The controller sets an increase of the accelerator position from a first accelerator position to a switching accelerator position at which a switch to the HV mode is to be made as a first increase when an output of a motor has reached an output upper limit at the first accelerator position. The controller sets an increase of the accelerator position from a second accelerator position to the switching accelerator position as a second increase which is smaller than the first increase when the output of the motor has reached the output upper limit at the second accelerator position which is larger than the first accelerator position.

Abstract: The present invention relates to: an electrical-power-feed connector connecting an electrical power source and an electrical-power-fed object, the electrical-power-feed connector having a configuration to form a signal path as a closed system, the signal path being to transmit a signal between the electrical-power-feed connector and the electrical power source, the signal having a value to vary depending on: an electrical connection status of the electrical-power-feed connector with the electrical power source, and an instruction to allow feeding of electrical power from the electrical power source to the electrical-power-fed object; and an electrical power source being feedable electrical power to an electrical-power-fed object by being connected with the electrical-power-fed object via the electrical-power-feed connector, the electrical power source having a configuration corresponding to the configuration of the electrical-power-feed connector.

Abstract: A PLG-ECU for external charging is provided separately from an HV-ECU for vehicle running, and configured to be capable of controlling external charging relays to be turned on/off. A sub DC/DC converter converting the output voltage of a charger into an auxiliary system voltage at the time of external charging is provided separately from a main DC/DC converter of large capacity used at the time of vehicle running. At the time of external charging, PLG-ECU can execute external charging without starting a vehicle running system while sub DC/DC converter can generate an auxiliary system voltage. Since external charging can be executed while system main relays each are kept turned off, a high voltage is not applied to components at the succeeding stage. Consequently, a main battery can be externally charged without exerting any influence on the durability and the life of each component of the vehicle running system.

Abstract: In the case that the motor travel priority mode is set and the restriction mode is set as the control mode because of the request of the operation of the engine, the threshold value Peg that is smaller value between the obtained value (kw·Wout) from multiplying the output limit Wout of the battery by the preset conversion factor kw and the preset power Pset that is smaller than the converted output limit Wout of the battery at a normal time is compared with the driving power Pdrv*. The hybrid vehicle is driven with the motor travel in idle operation of the engine when the driving power Pdrv* is not more than the threshold value Peg, and the hybrid vehicle is driven with power from the engine when the driving power Pdrv* is more than the threshold value Peg.

Abstract: When a gear of a transmission for transmitting torque of a motor to a drive shaft is shifted while an accelerator is off or an accelerator pedal is slightly stepped on, an upper limit rotation speed is set using a fluctuation rate of a value smaller than a value when the gear is not shifted, a target rotation speed of an engine is set using this upper limit rotation speed, and control is carried out so that an engine is operated at the target rotation speed. By this arrangement, when the accelerator pedal is stepped on and a large torque demand is demanded, rise of the engine rotation speed is restricted, a portion used for raising the rotation speed in power outputted from the engine is made smaller, and a larger power can be outputted to the drive shaft.

Abstract: In the case that the motor travel priority mode is set and the restriction mode is set as the control mode because of the request of the operation of the engine, the threshold value Peg that is smaller value between the obtained value (kw·Wout) from multiplying the output limit Wout of the battery by the preset conversion factor kw and the preset power Pset that is smaller than the converted output limit Wout of the battery at a normal time is compared with the driving power Pdrv*. The hybrid vehicle is driven with the motor travel in idle operation of the engine when the driving power Pdrv* is not more than the threshold value Peg, and the hybrid vehicle is driven with power from the engine when the driving power Pdrv* is more than the threshold value Peg.

Abstract: In a drive system, where power from a motor is transmitted to a drive shaft and a transmission ratio is changed by a transmission, if the absolute value of the difference between the reference torque Tm2r0, which is the drive shaft side torque Tm2r at the onset of a change in the shift speed of the transmission, and the driving shaft side torque Tm2r during the change is less than the threshold value ? until the end of the change (S280), the application state of a brake in the transmission during the change and the state of the hydraulic pressure supplied to the brake are learned (S290). During the change, and actuator of the transmission is controlled using those learned results. Accordingly, any deviations that may have occurred due to changes over time in the transmission, etc. are corrected and the shift speed of the transmission is changed more appropriately.

Abstract: In the presence of a torque change request (step S170) for changing a torque Tm2 of one motor MG2 to enable a smooth gearshift of a transmission interposed between a motor and a driveshaft, when the change of the torque Tm2 is unattainable within the range of an input limit Win and an output limit Wout of a battery (step S200), the power output apparatus of the invention resets a torque command Tm1* of the other motor MG1 to be within the input limit Win and the output limit Wout of the battery (steps S210 and S250). The power output apparatus also resets an engine power demand Pe* to make a rotation speed Ne of an engine approximately equal to a target rotation speed Ne* (steps S230 and S270). This arrangement ensures a smooth gearshift of the transmission.

Abstract: In response to the driver's depression of a brake pedal in requirement of catalyst deterioration control with a catalyst deterioration control flag Fc set equal to 1, the braking control of the invention controls the operation of a motor to make a rotation speed Ne of an engine approach to a target rotation speed Ne* in a state of continued combustion (firing) of the engine (steps S180 and S190). Such control ensures a quick decrease of the rotation speed Ne of the engine to the target rotation speed Ne*, thus effectively reducing the wasteful fuel consumption due to the continued operation of the engine at a high rotation speed and enhancing the overall energy efficiency of the vehicle.

Abstract: In a vehicle having a planetary gear mechanism to which an engine, a first motor, a drive shaft and a second motor are connected, while the engine is stopped, an increase rate (?Tr) by which required torque (Tr*), which is the torque required to be output to a drive shaft, is allowed to increase, is set based on an output limit (Wout) of a battery and an actual torque (T*) is set with the required torque (Tr*) limited by the set increase rate (?Tr) (S150, S160). A torque limit (Tmax) of the second motor is set by dividing the output limit (Wout) by the rotational speed of the second motor, and control is performed so that the actual torque (T*) is output from the second motor with the upper limit of the torque limit (Tmax) (S260 to S290).
