Claims

[Scope of utility model registration request]

An actuator that connects and disconnects the clutch between the vehicle's engine and transmission; □ An air supply solenoid valve installed in a passage that introduces air from this actuator and working air into the chamber; and an air supply solenoid valve that pulses the air in the air chamber. an exhaust electromagnetic valve that opens to the atmosphere at a time ratio according to the duty ratio of the signal; a gear selection means that selects the gear of the transmission to either a selected gear, a designated gear, or a reverse gear; and a brake. Detects failure of
A brake fail sensor controls the opening of the air supply solenoid valve, controls switching of the gear position of the transmission according to the target gear selected by the gear selection means, and then opens the exhaust solenoid valve. and when the gear selection means performs a downshift from the selected gear or the brake fail sensor detects a brake failure, the gear position of the transmission is shifted down one gear at a time together with the solenoid valve control. An automatic transmission device characterized by comprising a control unit for controlling the transmission.
