Claims

[Scope of utility model registration request]

A torque converter is interposed between the engine and the transmission, and a lock-up clutch and a power cutoff clutch that connect the input shaft and output shaft of the torque converter are interposed, and an output is output from the gear shift operation lever position detection means. In an automatic transmission system for a vehicle, the transmission is equipped with a control means that automatically performs a gear shift operation of the transmission and a connection/disconnection operation of the lock-up clutch and the power cut-off clutch based on a lever position detection signal detected by the transmission. a neutral position detection means for detecting the neutral position of the transmission; a vehicle speed detection means; and based on detection signals from both of the detection means, the idle rotation of the engine is increased when the transmission is not in the neutral position and the vehicle speed is below a predetermined value. An automatic transmission device for a vehicle, comprising an idle rotation control means.
