Claims

[Scope of claim for utility model registration] A braking start detection switch that detects the depression of the brake pedal and generates a detection signal, a vehicle speed sensor that detects vehicle speed, and a deceleration detection means that determines deceleration from the vehicle speed detected by the vehicle speed sensor. A determining means for determining whether the deceleration detected by the speed detecting means is greater than a predetermined deceleration and generating a determination signal when the deceleration is larger than a predetermined deceleration; the braking start detection switch generates a detection signal; a shift-down command means for generating a shift-down command signal to the transmission control device so as to downshift the gear position of the automatic transmission when the automatic transmission is shifted down;
′ A shift down command device.
