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 driver's request driving force, a driving unit (16) including an electric motor (EM) and applying driving force to a vehicle (12), a driving force control unit (22) controlling the driving unit based on a command driving force, and 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. The vehicle body vibration control device (10) further includes a notch filter control unit (26) variably setting a notch degree of the notch filter based on a shift position or a traveling mode unique to the vehicle including the electric motor.

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; and 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, the notch filter having a notch frequency set to a value for reducing a frequency component of vibration of a vehicle body, wherein said driving unit comprises an electric motor and a driving force transmission unit configured to transmit a driving force generated by said electric motor to driving wheels, wherein said driving force transmission unit is configured to switch, through a shifting operation performed by the driver, a driving force transmission position at least between a standard driving force transmission position and a deceleration driving force transmission position for generating a deceleration action by said electric motor, and wherein said vehicle body vibration control device further comprises a notch filter control unit configured to variably set a notch degree of said notch filter in accordance with said driving force transmission position.
