Control device for IC engine throttle setting mechanism - uses electric stepping motor with open regulation loop when engine is idling

摘要

The control device (10) detects the engine idling mode to provide control signals for the setting mechanism stepping motor (74) independent of the operating parameters, with a measuring device (46) detecting the position of the setting mechanism. When the idling mode is detected, the throttle (100) is controlled via the setting motor using an open control loop, with a closed control loop for regulating the throttle position outside the idling range, ensuring that the actual throttle position corresponds to the required throttle position. ADVANTAGE - Improved throttle position control using nonlinear torque characteristic.
