Damping control device for hybrid vehicle

A damping control device for a hybrid vehicle having

• a drive source including an engine and a motor;
• a target driving torque calculation unit that calculates a target driving torque by the engine and the motor based on an accelerator position opening amount and a vehicle speed;
• a motor torque calculation unit that calculates a target motor torque of the motor, that corrects the target motor torque and calculates a final target motor torque by a feed forward control that inputs the target motor torque of the motor obtained from the target driving torque, then attenuates and outputs the target motor torque, and a feedback control that inputs the motor rotational speed, and adds a torque for attenuating a vibration component caused by an actual disturbance to the output by the feed forward control,
• the damping control device comprising:
• a target driving torque change amount calculation unit that calculates a target driving torque change amount, which is a time-differential of a target driving torque;
• a target motor torque change amount calculation unit that calculates a target motor torque change amount, which is a time-differential of a target motor torque;
• and
• a damping rate variation unit that sets a damping rate by the feed forward control 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.
