Control system for stepping motor throttle setting device in automobile - using disparity between actual position and position control valve to provide correction without feedback regulation

摘要

The control system (10) provides a control valve for the stepping motor (48) in dependence on monitored operating parameters and the actual position of the setting device. When the difference between the actual position of the setting device and the given position control value is greater than a threshold value, the position control value is corrected by a given amount. Pref. the control value is independent of the position of the setting device, the adjustment effected without feedback regulations. ADVANTAGE - Rapid correction to ensure min. effect on travel characteristics.
