Claims

[Scope of utility model registration request]

Clutch operation means for engaging and disengaging the clutch, shift operation means for shifting the transmission, and engine rotation control means for controlling the rotation of the engine; In the automatic transmission system for a vehicle, the clutch operating means is controlled by a master cylinder interlocked with a clutch pedal, and a hydraulic pressure from the master cylinder. The clutch booster includes a hydraulic piston to be operated and a power piston connected to the hydraulic piston and operated by air pressure from an air supply source, and a clutch booster that is operated by hydraulic pressure from the master cylinder to generate air. a first air circuit equipped with a valve device that selectively guides air to the clutch booster; and a second air circuit equipped with a normally closed solenoid valve that selectively guides air to the clutch booster. , a normally open solenoid valve is interposed in the first air circuit, and when a clutch connection request is made during speed change control, the solenoid valve in the second air circuit is closed, and the solenoid valve in the first air circuit is closed. An automatic transmission for a vehicle, characterized in that it is provided with a clutch control means for closing a solenoid valve.
