Control device for an actuator closing /opening a turbocompressor with variable geometry equipping an engine for an automotive vehicle

摘要

The actuator control has units (6,7) to analyze the operating conditions of the engine and detect a request for a rapid increase in the engine torque. This data is used to enable the operation of devices (9-15) which generate a signal with its maximum limit progressively decreasing to control the turbo-charger actuator.
