御装置。 A control means inputs vehicle running conditions such as vehicle speed and a throttle opening signal, converts the signals into electrical signals, and outputs the signals. All gears are shifted according to a predetermined shift schedule using the output signals from the control means. and an interrupt control means for outputting a high-speed hold signal that prohibits shifting according to the shift schedule and sets the shift mode determining means to a high speed gear, Shifting of an automatic transmission characterized in that a low speed guarantee means is provided which cancels the high speed gear holding signal when the gear holding signal is output at a predetermined vehicle speed or lower and performs gear change control based on the output signal from the control means. Control device.
