Claims

[Scope of Claim for Utility Model Registration] A friction clutch connected to the engine, an actuator for the friction clutch, an engine rotation sensor for detecting the rotation speed of the engine, a gear type transmission connected to the friction clutch, and a clutch stroke. A clutch stroke sensor that detects the amount, an accelerator sensor that detects the accelerator position,
Engine rotation speed from the engine rotation sensor above,
A control unit receives the clutch stroke amount and the accelerator position and sets a duty ratio for the clutch actuator and an accelerator pseudo signal voltage for the fuel injection device, and the control unit controls the engine rotation from the engine rotation sensor. If the decrease in the engine speed is at a specified value or is not in a decreasing state, the peak of the engine speed is determined by determining whether the change in the engine speed continues within a predetermined range for a predetermined time, An automatic transmission device characterized by performing connection start processing at the time of starting.
