摘要:
A mode changeover control device (20) for a hybrid vehicle includes an engine (1), a motor/generator (5) and at least one driving wheel (2). A changeover between an electric drive mode using only the electric motor (5) to power the at least one driving wheel (2) and a hybrid drive mode using both the engine (1) and the electric motor (5) to power the at least one driving wheel (2) is controlled. The drive mode is changed from the hybrid drive mode to the electric drive mode if the accelerator opening (APO) is less than a first threshold level (γ), and the drive mode is changed from the electric drive mode to the hybrid drive mode if the accelerator opening is greater than a second threshold level (α). A hysteresis value is defined between the first threshold level and the second threshold level, and the hysteresis value is changed based on a vehicle operating state.
摘要:
A hybrid vehicle mode transition control apparatus includes a hybrid drive system having a first clutch disposed between an engine and a motor generator, and a second clutch disposed between the motor generator and wheels; an engine braking request judging section configured to judge whether a request of an engine braking is present during a motor regenerative braking performed by the motor generator, and a mode transition control section configured to perform a mode transition control of the hybrid drive system in accordance with a transition request. The mode transition control apparatus is configured to decrease a torque capacity of the second clutch being in an engaged state in response to the judgment that the request of the engine braking is present, and to bring the first clutch from a disengaged state to the engaged state to shift to the engine braking.
摘要:
A power transmission device is used to distribute torque from a power source (ENG) to an external device and an auxiliary device. The power transmission device is comprised of a first bearing (55) and a second bearing (12) both secured to a stationary member, a first sprocket (51) rotatably supported by the first bearing (55), a second sprocket (52) capable of being drivingly coupled with the auxiliary device, a chain (53) coupling the first sprocket (51) with the second sprocket (52), a rotary shaft (5) rotatably supported by the second bearing (12), which is drivingly coupled with the power source and drivingly engageable with the external device to transmit a first part of the torque to the external device, and a joint drivingly linking the rotary shaft (5) with the first sprocket (51) to transmit a second part of the torque to the first sprocket (51).
