の自動変速装置。 A torque converter with a lock-up clutch and a power cut-off clutch are installed in series between the engine and the multi-gear transmission, while a select shift actuator that operates the transmission gear shift and a gear shift operation in the driver's cab are installed. A select shift relay circuit that controls the drive of the select shift actuator via the select shift valve so as to select and shift the gears to be engaged according to the lever position, and a power cutoff clutch that is connected intermittently. a clutch actuator that controls the drive of the clutch actuator via a clutch valve to temporarily disengage the clutch during gear shift operation in conjunction with the select shift relay circuit, and a torque converter. A hydraulic lock-up actuator that engages and engages the lock-up clutch, and a lock-up controller that controls the drive of the lock-up actuator via a lock-up valve to disconnect the lock-up clutch when the vehicle speed is below a specified value. An automatic transmission system for a vehicle comprising: a brake relay interposed in parallel with the clutch relay for opening and closing the clutch relay circuit in conjunction with a brake switch of the vehicle when the lock-up clutch is disconnected. gearbox.
