Abstract
A vibration-suppression control device includes a processor calculating a rotation speed of a tire using an observer model including an observer model constant, and adding a damping torque, in which a gain adjustment corresponding to a gain constant is performed on a difference between the rotational speed of the tire and a rotational speed of the motor, to a torque of the motor. Further, the observer model constant is set in advance in a manner that the observer model constant in a state of during shifting is different from the observer model constant in a state of after shifting, and the processor uses the observer model, in which the observer model constant is switched between the state of during shifting and the state of after shifting.
Claims4
A vibration-suppression control device for a vehicle including an engine, a stepped transmission connected to the engine, and a motor connected to an output shaft side of the stepped transmission, the vibration-suppression control device comprising a processor configured to calculate a rotation speed of a tire using an observer model including an observer model constant, and add a damping torque, in which a gain adjustment corresponding to a gain constant is performed on a difference between the rotational speed of the tire and a rotational speed of the motor, to a torque of the motor, wherein
- the observer model constant is set in advance in a manner that the observer model constant in a state of during shifting in which a clutch of the stepped transmission is separated is different from the observer model constant in a state of after shifting where the clutch of the stepped transmission is connected, and
- the processor is configured to use the observer model, in which the observer model constant is switched between the state of during shifting and the state of after shifting.
