There are various demands concerning the motorcycle rider’s throttle input such as nonlinearly engine output attribute control and maximum speed control. To realize those demands by electronic control, we mounted the Drive-by-Wire (DBW) throttle system, which is currently being used on existing automobiles, to motorcycles, but the system failed to meet the demands of the motorcycle. Response to the throttle speed change was an issue; therefore, we built up the control system to satisfy the motorcycle’s demand for response by changing the high speed response equation of adaptive sliding mode control and adding the hysteresis property correction equation of the throttle body drive-train. As a result, we could realize response equivalent to that of a mechanical throttle.
