Abstract

The present invention is directed to a method of and an apparatus for detecting an angular velocity and a rotation angle of a rotary member. In the present invention, first and second accelerations at first and second points of the rotary member are detected, respectively. The first and second accelerations are added, while the first acceleration is subtracted from the second acceleration. From the added and subtracted values, then, an angular velocity and a rotary angle of the rotary member are calculated.
