Abstract:
1. A gear change control device for a straddle-type vehicle including a gear change command inputting device to which a gear change command is inputted, a gear change clutch, a gearbox, a gear position detecting device arranged to detect a gear position of the gearbox, a shift shaft, and an actuator arranged to engage and disengage the gear change clutch and changing gears of the gearbox by rotating the shift shaft from a reference angular position, the gear change control device comprising: a rotational angle detecting device arranged to detect a rotational angular position of the shift shaft; a target angular position setting device arranged to set a target angular position of the shift shaft based on an input from the gear change command inputting device; a rotational speed setting device arranged to set a rotational speed of the shift shaft based on the input from the gear change command inputting device; and a control unit programmed to calculate, based on an actual rotational angular position detected by the rotational angle detecting device and the target angular position set by the target angular position setting device, a difference between the actual rotational angular position and the target angular position, and to perform drive control of the actuator based on the calculated difference between the actual rotational angular position and the target angular position and the rotational speed set by the rotational speed setting device; wherein the control unit is programmed to change the rotational speed of the shift shaft set by the rotational speed setting device based on the gear position detected by the gear position detecting device.
