Claims

[Scope of utility model registration request]

Equipped with an automatic transmission that changes shifts according to a shift pattern, and means for changing the ratio of the throttle valve opening to the depression distance of the accelerator pedal;
An engine throttle valve control device comprising: a sensor for detecting engine rotation speed; and means for outputting a control amount to the displacement means to reduce the ratio in a low rotation range based on the engine rotation speed; A throttle valve control device for an engine, comprising means for determining whether or not the throttle valve is becoming smaller, and means for setting the shift pattern so as to delay a shift change when this is determined.
