Vehicle transmission system

A vehicle transmission system comprising:

• a transmission of which transmission is performed in accordance with an operation of a driver of a vehicle;
• a clutch device that is disposed between a power transmission path between the transmission and an engine of the vehicle and is coupled or decoupled in accordance with an operation of a clutch actuator;
• a clutch control unit that controls coupling/decoupling of the clutch device according to the clutch actuator;
• and
• a shift operation detecting means that detects a shift operation of the driver on a shift operator,
• wherein, when a hydraulic pressure is supplied from the clutch actuator to a slave cylinder, the clutch device moves to a connection side,
• wherein, in an in-gear stop state in which the transmission is in an in-gear state, and the vehicle is in a stop state, the clutch actuator supplies a standby hydraulic pressure to the slave cylinder, and
• wherein the clutch control unit sets the standby hydraulic pressure to a first setting value during non-detection in which the shift operation is not detected by the shift operation detecting means and sets the standby hydraulic pressure to a second setting value lower than the first setting value when the shift operation is detected by the shift operation detecting means.
