Smart actuator learn command process

An engine of a vehicle, comprising:

• a variable geometry turbocharger (VGT) having a VGT mechanism and a VGT actuator connected to the VGT actuator;
• and
• a controller connected to the VGT actuator and configured to monitor at least one entry condition and, if the at least one entry condition is met, to perform a learn procedure wherein the VGT actuator cycles the VGT mechanism through its range of motion following a key-off shutdown command before engine shutdown, and wherein the VGT actuator reports to the controller an available range of motion of the VGT actuator and of the VGT mechanism.

A method of determining the range of motion of a VGT mechanism and a VGT actuator of a VGT, comprising the steps of:

• monitoring with a controller at least one entry condition;
• if the at least one entry condition is met, performing a learn procedure wherein the VGT actuator cycles the VGT mechanism through its range of motion following a key-off shutdown command and before engine shutdown, and wherein the VGT actuator reports to the controller an available range of motion of the VGT actuator and of the VGT mechanism.
