THROTTLE CONTROL SYSTEM, THROTTLE CONTROL METHOD, AND MEMORY MEDIUM

A driving process causes a target angular position of a specific gear in a throttle device to reach an initial position by continuing to increase or decrease the target angular position at a constant speed. A determination process determines that wear has occurred on a gear mechanism in the throttle device based on a parameter related to a change speed of an angular position in a specific range during execution of the driving process. The specific range is a range from a specific angular position to the initial position. The specific angular position is the angular position that is separated from the initial position by a predetermined constant angle.
