Japanese Patent JP7066276
Kind Code:
B2
Abstract:
To control a timing of engagement by estimating a rotation angle of a gear tooth portion.SOLUTION: A rotation transmission mechanism 1 includes a rotation speed sensor 92 detecting a rotation speed of an output shaft 3, and a magnetic sensor 93 detecting an original point passing time of gear tooth portions 26 of shift gears 21, 22, 23. A control device 100 includes an estimation portion 102 for calculating a rotation angle θg of a tooth portion of the gear on the basis of a result of the detection of the rotation speed sensor 92, a reset portion 103 for resetting the rotation angle θg of the gear tooth portions 26 calculated by the estimation portion 102 to an original point according to input of the original point passing time detected by the magnetic sensor 93, and a drive control portion 105 for controlling a driving mechanism 15 on the basis of the rotation angle of the gear tooth portions 26. The reset portion 103 excludes the input of the magnetic sensor 93 at a timing different from the past input timing in resetting the rotation angle of the gear tooth portions 26.SELECTED DRAWING: Figure 1
