| 主权项 | 1. A turbocharger waste gate control system, comprising a controller including executable instructions stored in non-transitory memory to: determine a first threshold temperature and a second threshold temperature of a turbocharger waste gate; control an electronically actuated turbocharger waste including adjusting turbocharger waste gate actuation responsive to turbocharger waste gate actuator thermal elongation based on a waste gate actuator temperature, and reduce turbocharger waste gate actuator motor current in response to turbocharger waste gate actuator motor temperature being greater than the first threshold temperature of the turbocharger waste gate. | ||
