Claim 0:
1. A stabilizer system for a vehicle, comprising:
a stabilizer device including a stabilizer bar and a switch configured to switch a roll suppressing function of suppressing roll of a body of the vehicle by the stabilizer bar between an effective state in which the roll suppressing function is rendered effective and an ineffective state in which the roll suppressing function is rendered ineffective; and
a controller configured to determine whether a lateral acceleration of the body of the vehicle is greater than a threshold lateral acceleration and to control the switch to render the roll suppressing function effective when the lateral acceleration is greater than the threshold lateral acceleration and to render the roll suppressing function ineffective when the lateral acceleration is not greater than the threshold lateral acceleration,
wherein the controller selectively employs, as a determination lateral acceleration for determining whether the lateral acceleration is greater than the threshold lateral acceleration, a smaller one of an actual lateral acceleration obtained based on detection by a lateral acceleration sensor provided in the vehicle and an estimated lateral acceleration estimated based on a degree of turning of the vehicle without depending on the actual lateral acceleration.
