Claims

[Scope of utility model registration request]

A friction clutch connected to the engine, a clutch actuator that operates the friction clutch in a direction of disconnecting or connecting by introducing or discharging fluid, and a fluid supply means for supplying fluid to operate the clutch actuator. , a normally closed electromagnetic on-off valve X with a metal seal and a normally open electromagnetic on-off valve W with a rubber seal for fluid supply, which are interposed between the clutch actuator and the fluid supply means, and the fluid of the clutch actuator. a normally closed electromagnetic on-off valve Y that opens the clutch to the atmosphere, a normally open electromagnetic on-off valve Z that holds fluid in the clutch actuator, a gear type transmission connected to the friction clutch, and a gear of this gear type transmission. The gear position switching means switches the gear position, and the solenoid valves X, Y, and Z are controlled to open and close based on the driver's intention and the running conditions of the vehicle to shut off and connect the clutch, and the gear position switching means changes the gear position. What is claimed is: 1. A shift control device for an automatic transmission device, comprising: a control device for driving a vehicle by switching between the two modes.
