Abstract:
A suspension system for a vehicle including: a stabilizer apparatus configured to change a stabilizer force by an operation of an actuator, a pair of hydraulic shock absorbers configured to change damping coefficients thereof, and a control device which is configured to execute a body-roll damping control in which at least a part of the stabilizer force is controlled to act as a roll damping force having a magnitude in accordance with a roll speed of a body of the vehicle, which is configured to change, in the body-roll damping control, a degree of the magnitude of the roll damping force by the stabilizer force, and which is configured to control, under execution of the body-roll damping control, the damping coefficient of each absorber such that a component of the absorber force for damping roll of the vehicle body is controlled in accordance with the degree of the magnitude of the roll damping force by the stabilizer force, namely, such that the component of the absorber force becomes smaller in an instance where the degree of the magnitude of the roll damping force by the stabilizer force is high than in an instance where the degree of the magnitude of the roll damping force by the stabilizer force is low.
