In a vehicle equipped with an engine equipped with an idle speed control valve, detects the throttle operation means operated when controlling the engine idle with the throttle and the amount of operation of the throttle operation means, and outputs an electric signal corresponding to the amount of operation. A throttle operation amount sensor that detects the engine rotation speed, a rotation speed sensor that detects the engine rotation speed and outputs an electric signal corresponding to the same rotation speed, and an electric signal output from the throttle operation amount sensor, and inputs the electric signal output from the throttle operation amount sensor, The idle speed control valve is controlled to set a corresponding idle target rotation speed of the engine so that the engine rotates at the idle target rotation speed, and the electric signal from the rotation speed sensor is input to control the actual engine speed. The idle speed control valve recognizes the rotation speed and causes the actual engine rotation speed to match the idle target rotation speed when a difference occurs between the idle target rotation speed and the actual engine rotation speed. 1. A throttle control device comprising: a control means for correcting and controlling.
