Abstract

A shift control system includes an engine speed detector, a multistage transmission, a gear position detector, a shifting operation detector, and an output controller. The engine speed detector is configured to detect an engine speed. The gear position detector is configured to detect a transmission gear. The shifting operation detector is configured to detect an operation of a shift operating element. The output controller is configured to restrict output of an engine in a case where an up-shifting operation is detected by the shifting operation detector. The output controller is configured to release output restriction of the engine before the gear position detector detects that switching to a next-stage transmission gear by the up-shifting operation of the shift operating element is completed.

Claims20

Dependent claims

A shift control system comprising:

engine speed detecting means that detects an engine speed;
multistage transmission that switches engagement conditions of a dog clutch by displacing shift forks driven in an axial direction of a shift drum along with turning of the shift drum by an operation of a shift operating element, the dog clutch being constituted by meshing engagement between a driving side dog and a driven side dog of transmission gears respectively mounted to a main shaft and a countershaft;
gear position detecting means that detects a transmission gear;
shifting operation detecting means that detects an operation of the shift operating element;
and
an output control part that restricts output of an engine when an up-shifting operation is detected by the shifting operation detecting means,
wherein the output control part releases output restriction of the engine before the gear position detecting means detects that switching to a next-stage transmission gear by the up-shifting operation of the shift operating element is completed.
