Claims

[Scope of utility model registration request]

A vehicle speed detector that detects vehicle speed, a speed gear switching device that switches the speed gear of the transmission according to the vehicle speed, a forward/reverse switching device that switches the vehicle between forward and backward motion, and detects the forward/reverse state of the forward/reverse switching operating body. A control device is provided, which includes a forward/reverse motion detector that controls the speed of the vehicle, and switches and controls the speed gear switching means and the forward/reverse motion switching means based on output signals from the vehicle speed detector and the forward/reverse motion detector. a function of changing the downshift switching point to a higher vehicle speed than the normal driving state by outputting a switching signal from a forward/reverse detector and outputting a switching signal to the speed gear switching means; and a vehicle speed detected by the vehicle speed detector. An automatic transmission device for a vehicle, characterized in that it has a function of outputting a switching signal to the forward/reverse switching means when the vehicle decelerates to a predetermined low speed.
