装置。The current driving condition is determined by inputting various driving condition signals such as vehicle speed signal, intake negative pressure signal, mode signal, etc., and the optimum shift is performed by comparing the determination result with a pre-stored shift table. In an electronically controlled automatic transmission device that includes a microcomputer that determines the position and a solenoid that switches the shift position of the transmission by being driven in accordance with a shift control signal output from the microcomputer that indicates the optimal shift position, A pressure sensor that detects the operating force of the foot brake, and an analog-to-digital conversion circuit that converts the output signal of this pressure sensor into a digital value and supplies it to the microcomputer as a brake pressure signal are provided, and the microcomputer When the signal exceeds a set value, it is determined that a deceleration request has occurred, and the downshift position is determined based on the brake pressure signal and vehicle speed from a pre-stored deceleration map, and the corresponding solenoid is driven. An electronically controlled automatic transmission device characterized by sufficiently applying engine braking by executing downshift control.
