Stabilizer control apparatus
First Claim
1. A stabilizer control apparatus for a vehicle, comprising:
- a stabilizer including a pair of stabilizer bars disposed between a right wheel and a left wheel of said vehicle, and an actuator having an electric motor and a speed reducing mechanism disposed between said stabilizer bars, said stabilizer bars being mounted at free end portions thereof on said vehicle, respectively;
vehicle state detection means for detecting a vehicle behavior and a steering operation of a vehicle driver;
desired torque calculation means for calculating a desired torque for said electric motor on the basis of the result detected by said vehicle state detection means;
end torque estimation means for estimating a torsional torque created on each end portion of each of said stabilizer bars mounted on said vehicle; and
feedback control means for controlling said electric motor in response to the result compared between the desired torque calculated by said desired torque calculation means and the torsional torque estimated by said end torque estimation means.

Abstract
In a stabilizer control apparatus for a vehicle, a stabilizer includes a pair of stabilizer bars disposed between a right wheel and a left wheel of the vehicle, and an actuator having an electric motor and a speed reducing mechanism 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.
