  • Shift control system for saddle-type vehicle
    Patent number: 10876624
    Abstract: There is provided a shift control system for a saddle-type vehicle. A gear shift lever is configured to be operated by a driver. A gearshift sensor is configured to detect an operation on the gear shift lever. A shift cam is configured to rotate according to the operation on the gear shift lever. A gear position sensor is configured to detect a rotation angle of the shift cam. In the case where the gearshift sensor does not detect a detection result according to a detection result of the gear position sensor, or in the case where the gear position sensor does not detect a detection result according to a detection result of the gearshift sensor, a control device determines abnormality occurrence, and stops engine operation control based on the detection results of the gearshift sensor and the gear position sensor on the basis of the abnormality occurrence.
