Stabilizer control apparatus

摘要

In a stabilizer control apparatus for a vehicle, a stabilizer includes a pair of stabilizer bars (SBfr,SBfl) disposed between a right wheel and a left wheel of the vehicle, and an actuator (FT,RT) having an electric motor (M) and a speed reducing mechanism (RD) disposed between the stabilizer bars. A desired torque for the electric motor is calculated on the basis of a vehicle behavior and a steering operation of a vehicle driver, and estimated is a torsional torque created on each end portion of each of the stabilizer bars mounted on the vehicle. According to a feedback controller, the electric motor is controlled in response to the result compared between the desired torque and the estimated torsional torque.
