PROBLEM TO BE SOLVED: To provide a stabilizer control device capable of rapidly and smoothly controlling the torsional torque at a mounting end of a pair of stabilizer bars on a vehicle, and adequately suppressing the roll motion of a vehicle body. SOLUTION: In the stabilizer control device to control the torsional force of a stabilizer by controlling an electric motor M, the target torque (r) to the electric motor M is operated based on the result of detection of a vehicle state detection means (the lateral acceleration Gy, the yaw rateγ, the vehicle speed Vs and the steering angleδ). On the other hand, the torsional torque generated at the mounting end of a pair of stabilizer bars on a vehicle is estimated by a torque estimator TE. The electric motor is feedback-controlled according to the result of comparison (deviation e) between the estimated torque (y) and the target torque. COPYRIGHT: (C)2005,JPO&NCIPI
