Title: Rotation-angle detector
Inventor: INABA MITSUNORI
IPC: G01B7/00
Filed: 2000-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a rotation-angle detector which detects an absolute rotation angle with a simple structure and at low costs. SOLUTION: The rotation angle of a crank shaft is found by detecting the difference of a commutation signal by a sensor magnet by which an ACG stator connected to the crank shaft of an engine is made to function as a brushless motor and by a Hall element. Even when a plurality of numbers of times (a, b, c, d) of the repetition of an identical pattern are generated during one rotation, the position of a reference commutation signal pattern d4 generated when a rotational speed is dropped in a compression operation can be specified as a prescribed rotation angle. The generation position of the pattern d4 which is closest when the rotational speed is dropped is used as the prescribed rotation angle, and the absolute rotation angle is found according to the generation of a commutation signal pattern after that.  Consequently, it is not required to install a rotation angle sensor separately, and the absolute rotation angle can be detected simply and at low costs.
