Abstract:
1. A stabilizer control apparatus for controlling a torsional rigidity of a stabilizer disposed between a right wheel and a left wheel of a vehicle to control a rolling motion of a vehicle body actively in response to turning operation of said vehicle, comprising: actual lateral acceleration obtaining means for obtaining an information indicative of actual lateral acceleration of said vehicle; calculated lateral acceleration obtaining means for obtaining an information indicative of calculated lateral acceleration of said vehicle, in response to steering operation of said vehicle; and control target setting means providing a first control gain for the actual lateral acceleration obtained by the actual lateral acceleration obtaining means and a second control gain for the calculated lateral acceleration obtained by the calculated lateral acceleration obtaining means, said control target setting means setting a control target on the basis of a first product of the actual lateral acceleration multiplied by the first control gain and a second product of the calculated lateral acceleration multiplied by the second control gain, said control target setting means setting the first control gain to be zero when said vehicle is moving straight to set an influence amount of the actual lateral acceleration to the control target to zero, and said control target setting means setting the first control gain to be increased with the turning operation of said vehicle being increased; and control means for actively controlling the rolling motion of said vehicle body by controlling the torsional rigidity of said stabilizer on the basis of the control target set by said control target setting means.
