VEHICLE BODY ATTITUDE CONTROL APPARATUS
First Claim
1. A vehicle body attitude control apparatus for controlling an attitude of a vehicle body of a vehicle, the apparatus comprising:
- a target pitch state calculation unit configured to calculate a target pitch state as a target value of a pitch state of the vehicle body according to a roll state of the vehicle body; and
a pitch moment generation unit configured to generate a pith moment to be applied to the vehicle body so that the pitch state of the vehicle body approaches the target pitch state.

Abstract
The present invention provides a vehicle body attitude control apparatus capable of improvement of cornering operability, steering stability, and a 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 of front left, front right, rear left, and rear right wheels so as to achieve the target pitch rate, and generates a pitch moment to be applied to the vehicle body accordingly.
