Abstract:
1. A stabilizer system comprising: a stabilizer bar that connects a left wheel and a right wheel of a vehicle to each other and that suppresses a roll of the vehicle by torsional reaction force; an actuator that controls a relative torsional amount between a side of the left wheel and a side of the right wheel of the stabilizer bar; and a control device that controls the actuator, wherein the actuator selectively operates in one of wherein the control device executes torsional amount control to approximate the torsional amount to a target torsional amount by allowing the actuator to alternately operate in the permitting mode and in the regulating mode, when the torsional amount becomes larger than the target torsional amount which is a target value of the torsional amount, wherein the control device makes a degree of regulation of the increase and decrease in the torsional amount by the regulating mode lower from a start of the torsional amount control until a predetermined state set in advance is reached than the degree after the predetermined state is reached, wherein the regulating mode is a brake mode to allow a brake to act for operation in a direction to increase/decrease the torsional amount in the actuator, wherein the actuator adjusts a strength of the brake in the brake mode, and wherein the control device decreases the degree of regulation until the predetermined state is reached by at least one of a decrease in the strength of the brake in the brake mode and a decrease in ratio of a time period during which the actuator is allowed to operate in the brake mode in the torsional amount control.
