ABSTRACT:
A vehicular tilt-angle detecting apparatus includes a steering-angle sensor, a vehicle speed sensor, a lateral-G sensor, a turning-radius calculation unit, a base tilt-angle calculation unit, a transient tilt-angle calculation unit, and a transient tilt angle calculation unit. The turning-radius calculation unit determines a turning radius corresponding to a steering angle based on a predetermined relationship between a steering angle and a turning radius. The base tilt-angle calculation unit calculates a current instantaneous tilt angle of a vehicle body during short-term steady-state turning based on the turning radius and the vehicle speed. The transient tilt-angle calculation unit corrects the initial calculated tilt angle of the vehicle body based on a transient turning radius when a variation of the steering angle is equal to or greater than a predetermined value. When the variation is less than the predetermined value, the transient tilt-angle calculation unit calculates the lateral-G corrected transient tilt angle.
