Abstract: Provided herein are anti-rattle devices and turbocharger wastegate assemblies including the same. The device can include a body having a first end and a second end, a bend, wherein the bend and the first end define a first section of the body, and the bend and the second end define a second section of the body, a cavity defined by the first section, the bend, and the second section, and an aperture extending between the first section and the second section. The device can include a U-shaped base defining an aperture and an open end, and at least one spring arm attached proximate the open end of the base bend and extending away from the open at least partially overlapping the base and defining a gap therebetween. The anti-rattle devices can be spring-loaded and can mate with a turbocharger wastegate assembly in one or more positions and provide anti-rattling benefits.

Abstract: A method for controlling an electric actuator of a turbocharger in a vehicle propulsion system includes determining whether an internal combustion engine in the vehicle propulsion system is operating, determining whether an actuation condition is satisfied, and operating the electric actuator a first time in response to a determination that the internal combustion engine in the vehicle propulsion system is not operating and that the actuation condition is satisfied.
