Abstract

[Object]~It is an object of the present invention to provide an electric-power-assist-type transmission and a shift control method which allow good operatability to be obtained.
[Solution Means] In a shift control method to be adopted in an electric-power-assist-type transmission for engaging a sleeve with a target gear whereby a shift spindle is rotated by a driving motor in order to move the sleeve along a main shaft by using a shift fork and a shift drum interlocked with the shift spindle, when the sleeve is moved to a position in contact with the target gear, PWM
control is executed at a duty ratio of 70% during the first 20 mS. Thereafter, the PWM control is executed by changing the duty ratio to 50% and restoring the duty ratio back to 70% repeatedly at intervals of 10 mS.
