Title: Engine control apparatus

Abstract: An engine control apparatus includes an ISS control unit provided with an ISS determination unit for inputting at least an engine cooling water temperature, vehicle speed, and brake information, and target opening setting unit for setting a target opening in an idle stop/start control period. A throttle control unit is provided with a proportional gain correction coefficient operator for correcting a proportional gain to a value that is larger than a proportional gain outside the idle stop/start control period, a throttle opening feedback controller for performing throttle opening feedback control based on an opening deviation between a target opening and an actual opening, and a PWM driver outputting a voltage proportional to the operation amount, to a motor.
