Vehicle body attitude control apparatus

摘要

A vehicle body attitude control apparatus capable improving cornering operability, steering stability, and ride comfort while a vehicle is running. A controller includes a gain, a determination unit, a multiplication unit, an FF control unit, a difference calculation unit, an FB control unit, an average value calculation unit, a target damping force calculation unit, and a damper instruction value calculation unit so as to enable such control that a pitch rate and a roll rate are set into a proportional relationship while the vehicle is cornering. The controller calculates a target pitch rate proportional to the roll rate, variably controls a damping force characteristic of a damping force variable damper disposed at each the wheels so as to achieve the target pitch rate, and generates a pitch moment to be applied to the vehicle body.

1. A vehicle body attitude control apparatus for controlling an attitude of a vehicle body of a vehicle, the apparatus comprising:
a target pitch rate calculation unit configured to calculate a target pitch rate as a target value of a pitch rate of the vehicle body by multiplying a detected roll rate signal by a predetermined gain so that the target pitch rate increases according to a roll rate of the vehicle body; and a pitch moment generation unit configured to generate a pitch moment to be applied to the vehicle body so that the pitch state of the vehicle body approaches the target pitch rate.
