VEHICLE BODY VIBRATION CONTROL DEVICE FOR VEHICLE

摘要

Provided is a vehicle body vibration control device (10) for a vehicle, including a request driving force calculation unit (20) calculating a driver's request driving force, a driving unit (16) applying a driving force to a vehicle (12), a driving force control unit (22) controlling the driving unit based on a command driving force, a notch filter (24) receiving a signal indicating the request driving force, processing the signal so as to reduce a frequency component of vibration of a vehicle body, and outputting the processed signal to the driving force control unit as a signal indicating the command driving force, and a command driving force correction unit 30 correcting, when any one of a predetermined shifting operation and a predetermined changing operation for a vehicle traveling mode is performed, the command driving force to the driver's request driving force of the driver.

主权项

1. A vehicle body vibration control device for a vehicle, comprising:
a request driving force calculation unit configured to calculate a request driving force of a driver; a driving unit configured to apply a driving force to the vehicle; a driving force control unit configured to control said driving unit based on a command driving force; a notch filter configured to receive a signal indicating the request driving force from said request driving force calculation unit, subject the signal to filter processing, and output the signal subjected to the filter processing to said driving force control unit as a signal indicating the command driving force, said notch filter having a notch frequency set to a value for reducing a frequency component of vibration of a vehicle body; and a command driving force correction unit configured to correct, when the driver performs any one of a predetermined shifting operation and a predetermined changing operation for a vehicle traveling mode, the command driving force to a value closer to the request driving force of the driver than to the command driving force.
