Abstract
Official abstract text for this publication.
Method for regulating the control of an electrical wastegate actuator controlled via an H bridge to permit displacement of the wastegate in its closure and opening directions according to whether the current passes through the actuator in one or opposite direction, includes: determining a set position which the wastegate has to reach, and an activation time of the actuator defining a monitoring time; applying a control signal to the actuator to displace the valve into the set position; measuring the current passing through the H bridge and applying a correction factor to the current to obtain the motor torque; obtaining the displacement speed of the wastegate by integration of the motor torque; obtaining the position reached by the wastegate at the end of the monitoring time by integration of the speed; comparing the position reached with the set position; and repeating the method until the set position is reached.
First claim
Opening claim text (preview).
1 . A method for regulating the control of an electrical actuator of a valve permitting the exhaust gases of an internal combustion engine to be diverted from the fluid supply circuit of a turbine of a turbocharger designed to compress the fresh gases admitted into the air intake circuit of said internal combustion engine, said electrical actuator being controlled by means of an H bridge in order to permit a displacement of the valve in the direction of its closure and in the direction of its op…
