Abstract:
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 to output the signal, which has been 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 notch filter calculates the command driving force at every predetermined time interval based on a past request driving force, a current request driving force, and a past command driving force, wherein said vehicle body vibration control device further comprises a determination unit configured to determine whether or not there is a need to correct the command driving force to a value reduced in effect of said filter processing, and a command driving force correction unit configured to correct, when said determination unit determines that there is a need to correct the command driving force, the command driving force to the value reduced in effect of said filter processing, and wherein said command driving force correction unit corrects, when said determination unit determines that there is no more need to correct the command driving force, in calculation of a command driving force executed immediately after the determination, said notch filter so as to calculate the command driving force by using the current request driving force in place of the past request driving force and the past command driving force.
