Claims

[Scope of utility model registration request]

The optimum gear stage is selected based on vehicle information such as vehicle speed, engine speed, and accelerator opening, the clutch actuator is operated to engage and disengage the clutch, and the gear shift unit of the transmission is operated to change the gear position. In an automatic transmission system that automatically switches to an optimal gear, there is a gradient sensor that detects the gradient of the road surface in the direction of vehicle travel, and when this gradient sensor detects a gradient angle that is greater than a specified value, the clutch is disengaged and the gear is shifted. After switching the gear position of the machine to 1st gear, a 1st gear start signal is output that engages the clutch, and when the gradient sensor detects a gradient angle that is less than a specified value, the clutch is disengaged and the gear of the transmission is shifted. A slope starting device characterized by comprising a control unit that outputs a 2nd speed start signal that connects a clutch after switching the position to 2nd speed.
