Vehicular vibration damping control device and vehicle mounted with vibration damping control device

摘要

A vehicular vibration damping control device that performs vibration damping of pitch/bounce vibrations of a vehicle through drive output control includes a vibration damping control portion that controls a driving torque of an engine to perform pitch/bounce vibration damping, and a compensation component adjustment portion that reduces the magnitude of a compensation component for compensating for a wheel torque calculated by the vibration damping control portion on the basis of an amount of change in the throttle opening degree of the engine. The compensation component is reduced when the temperature of a conductor for supplying a current to a throttle motor for adjusting a throttle opening degree estimated on the basis of the amount of change in throttle opening degree becomes higher than a predetermined value.

1. A vehicular vibration damping control device that performs vibration damping control of damping pitch vibrations or bounce vibrations of a vehicle through control of a drive output of the vehicle, comprising:
a vibration damping control portion that controls a driving torque of an engine in such a manner as to restrain an amplitude of the pitch vibrations or the bounce vibrations on a basis of a wheel torque acting on each wheel of the vehicle, which is generated at a location of a road surface where the wheel is grounded; and a compensation component adjustment portion that alters a magnitude of at least part of a compensation component for compensating for the wheel torque for the vibration damping control, which is calculated by the vibration damping control portion, on a basis of a temperature of a throttle motor for adjusting a throttle opening degree of the engine, wherein the compensation component adjustment portion which compensates the wheel torque for the vibration damping control estimates a temperature of a conductor for supplying a current to the throttle motor for adjusting the throttle opening degree on a basis of an amount of change in the throttle opening degree, wherein the compensation component adjustment portion which compensates the wheel torque for the vibration damping control reduces the magnitude of at least part of the compensation component when the temperature of the conductor becomes higher than a predetermined value, and wherein the compensation component adjustment portion reduces the magnitude of at least part of the compensation component for compensating for the wheel torque when a frequency or amplitude of the amount of change in the throttle opening degree becomes equal to or larger than a predetermined value.
