Claims

[Scope of utility model registration request]

A torque converter with a lock-up clutch and a power cutoff clutch are interposed between the engine and the multi-stage gear transmission, while a gear shift actuator that shifts gears of the transmission and a lock that connects and connects the lock-up clutch of the torque converter are installed. In an automatic transmission system for a vehicle, which includes an up actuator, a clutch actuator that connects and connects a power cutoff clutch, and a shift change control means that drives these actuators to control a speed change operation, means for detecting vehicle speed; , a lock-up control means for controlling a lock-up actuator to connect a lock-up clutch in a vehicle speed range equal to or higher than a predetermined low speed value after completion of a starting operation based on the detection signal. gearbox.
