摘要： A damping control device for a hybrid vehicle is provided that make it possible to suppress behavior that differs from a request of a driver. The damping control device includes a controller that calculates an amount of change in a target driving torque, and calculates an amount of change in a target motor torque. The damping control device also includes a damping rate variation unit that sets the damping of a feed forward control unit to a first damping rate when the target driving torque change amount and the target motor torque change amount both are positive or negative, and to a second damping rate, which is smaller than the first damping rate, when the target driving torque change amount and the target motor torque change amount have opposite positivity or negativity.

摘要： A driving control method for a hybrid vehicle is provided to overcome a slip of the vehicle by a conversion of an EV mode into an HEV mode. The driving control method includes: determining by a controller whether the hybrid vehicle is insufficiently driven backward only by power of a motor when the vehicle is driven backward on an uphill road by driving the motor backward; starting an engine and engaging a backward stage gear; releasing a first clutch and at the same time requesting a brake operation signal to the hybrid vehicle while the motor is converted into forward driving; and then engaging a second clutch and requesting a brake release signal to the hybrid vehicle while an engine clutch is engaged to control the hybrid vehicle to be started by the power of the motor and the engine.

摘要： In the case that operation stop of the engine is requested while the clutch is engaged and the engine is driven at a higher rotation speed than the resonance rotation speed band, the clutch is disengaged and the engine is driven in the self-sustaining operation at the self-sustaining rotation speed higher than the resonance rotation speed band, the rotation speed Ne of the engine is lowered less than or equal to the second rotation speed Nref2 lower than the resonance rotation speed band with stop of fuel injection into the engine and the partially-engaged clutch after the rotation speed Nm of the motor MG becomes less than or equal to the first rotation speed Nref1 predetermined as a rotation speed lower than the resonance rotation speed after the clutch is disengaged. The rotation speed of the engine is therefore enabled to pass more rapidly through the resonance rotation speed band.
