Abstract: An engine includes a turbocharger that boosts suctioned air to be fed to the engine. A boost line is determined on a map representing a relationship between the rotation speed of the engine and torque generated by the engine, and the turbocharger boosts suctioned air when the torque generated by the engine indicated by an operating point on the map exceeds the boost line. An HV-ECU controls the engine and a first MG to increase the rotation speed of the engine, depending on the atmospheric pressure, before the torque generated by the engine indicated by the operating point exceeds the boost line, and when the HV-ECU increases the rotation speed of the engine, for lower atmospheric pressure the HV-ECU controls the engine and the first MG to increase the rotation speed more than for higher atmospheric pressure.

Abstract: In a hybrid vehicle, each of an engine and an MG1 is mechanically coupled to a drive wheel with a planetary gear being interposed. The planetary gear and an MG2 are configured such that motive power output from the planetary gear and motive power output from the MG2 are transmitted to the drive wheel as being combined. When a first condition is satisfied during traveling of the vehicle, a controller stops combustion in the engine and performs motoring by the MG1 such that the planetary gear outputs deceleration torque. When a second condition in addition to the first condition is satisfied (YES in S20) during deceleration of the hybrid vehicle with deceleration torque, the controller performs motoring with throttle opening being set to first opening or larger and WGV opening being set to second opening or smaller.

Abstract: An HV-ECU performs processing including calculating estimated engine torque based on a previous value of a time constant, setting as the time constant, a first value corresponding to a forced induction range when engine torque is determined as being in the forced induction range, setting as the time constant, a second value corresponding to a non-forced induction range when engine torque is determined as not being in the forced induction range, calculating a feedforward term Tgff, calculating a feedback term Tgfb, calculating a torque command value for a first MG, and outputting a first MG torque command.

Abstract: An HV-ECU performs processing including calculating requested system power, calculating requested engine power when an engine activation request has been issued, obtaining a turbo temperature, setting an operating point on a predetermined operating line when the turbo temperature is equal to or lower than a threshold value Ta, setting as the operating point, a position on a higher rotation speed side by a predetermined value along an equal power line when the turbo temperature is higher than the threshold value Ta, carrying out engine control, and carrying out MG control.

Abstract: When a prescribed execution condition is satisfied at the time of transition from HV traveling (that is, traveling performed by an engine and a motor with generation of traveling driving force by the engine) to EV traveling (that is, traveling performed by the motor without generation of traveling driving force by the engine), a controller of a hybrid vehicle performs motoring (or a self-sustaining operation) of an engine and thereafter stops the engine.

Abstract: In a hybrid vehicle, each of an engine and an MG1 is mechanically coupled to a drive wheel with a planetary gear being interposed. The planetary gear and an MG2 are configured such that motive power output from the planetary gear and motive power output from the MG2 are transmitted to the drive wheel as being combined. A controller makes WGV diagnosis for diagnosing whether or not a waste gate valve is normally controllable by issuing an instruction to a WGV actuator while the controller stops combustion in the engine and controls the MG1 and the MG2 in coordination to perform motoring of the engine during traveling of the hybrid vehicle.

Abstract: In a drive control system for a vehicle configured to cause the vehicle to travel in a limp-home mode when a malfunction occurs in a selectable one-way clutch, when it is determined that a malfunction occurs in the SOWC, the cause of the malfunction is specified as one of a plate-open failure of a selector plate that is unintentionally placed in an open state, and a sensor failure. In the case of the plate-open failure, a first limp-home traveling mode is carried out in which the vehicle travels in the limp-home mode while keeping the SOWC in a negative rotational speed range. In the case of the sensor failure, a second limp-home traveling mode is carried out in which the vehicle travels in the limp-home mode while the SOWC is placed in the non-engaged state.

Abstract: A controller for a hybrid vehicle is provided. The hybrid vehicle includes an engine, a first electric motor, a second electric motor, a power split mechanism, and a selectable one-way clutch. The hybrid vehicle is configured to increase and transmit a rotation speed of the engine to an output shaft to drive the output shaft in an overdrive state when the selectable one-way clutch is in the engaged state. The controller includes an electronic control unit configured to control the first electric motor such that an engine brake equivalent torque with a magnitude sufficient to maintain the locked state of the selectable one-way clutch is output in a direction opposite to a direction of a negative torque which is generated in the engine when the hybrid vehicle travels in a state in which supply of fuel to the engine is stopped in the overdrive state.

Abstract: A selectable one-way clutch includes a first plate, a second plate, a claw, a selector plate and an interposition member. The claw is provided in the first plate. The claw projects from the first plate toward the second plate. The claw meshes with a recessed portion disposed in the second plate when the second plate rotates in a predetermined rotation direction and the claw projects from the first plate. The selector plate is placed so as to be adjacent to the first plate. The selector plate rotates relative to the first plate between a locked position at which the claw is projectable and a released position at which the claw is maintained. The interposition member is placed between the selector plate and the second plate. Rotation of the interposition member relative to the selector plate is restricted.

The selector plate rotates relative to the first plate between a locked position and a released position. The plate driving device includes a drive arm, an actuator, a transmission mechanism, a stopper and a release mechanism. The actuator outputs a driving force to drive the selector plate via the drive arm. The transmission mechanism transmits the driving force to the drive arm such that the selector plate rotates from the released position to the locked position. The stopper is configured to move between a restricted position and an unrestricted position. The stopper is placed at the restricted position when the actuator is not operated. The release mechanism transmits the driving force to the stopper such that the stopper moves from the restricted position to the unrestricted position.

Abstract: The hybrid drive device of the present invention includes a selectable one-way clutch 12 that includes a rotational plate that is capable of receiving the reaction torque of an internal combustion engine and that is provided to a power split mechanism, and that can be changed over between: a locked mode in which, in the state of receiving the reaction torque, positive rotation of the rotational plate is prevented while negative rotation of the rotational plate in the direction opposite to the positive rotation is permitted; and a free mode in which, in the state of receiving the reaction torque, the positive rotation and the negative rotation of the rotational plate are both permitted. And, when misfiring of the internal combustion engine occurs, the selectable one-way clutch is kept in the free mode.
