1. A vehicle control apparatus comprising:

  • a vehicle speed sensor for detecting speed of a vehicle;

    at least one angular velocity sensor for detecting angular velocity about a pitch axis, a yaw axis or a roll axis of said vehicle;

    a zero-point calculation means which detects a normal state of said vehicle by using output signals of said vehicle speed sensor and output signals of said angular velocity sensor, and which calculates an average of said output signals of said angular velocity sensor in said normal state, said average of said output signals of said angular velocity sensor corresponding to a zero-point signal;

    an angular velocity correction means which corrects said output signal of said angular velocity sensor by using said zero-point signal calculated by said zero-point calculation means;

    a turning state inference means which infers a rolling state of said vehicle from said corrected signal output from said angular velocity correction means and an output signal of said vehicle speed sensor, and further produces output signals for controlling said rolling state of said vehicle; and

    shock absorber means whereof a damping force is adjusted in response to said output signals from said turning state inference means.
