US 11,959,550 B2 · Actuation mechanism

Abstract

An actuation mechanism for use in a vehicle. The actuation mechanism includes one or more motors having an output shaft with a sun gear. At least a portion of the sun gear is drivingly connected to at least a portion of one or more planetary gears. The one or more planetary gears are drivingly connected to at least a portion of a carrier, a fixed non-rotating ring gear and an output gear. The disclosure further relates to a method of operating an actuation mechanism that is drivingly connected to at least a portion of a vehicle parking mechanism. The method includes providing an actuation mechanism, providing a parking mechanism and one or more sensors that are operably configured to collect an amount of data to be analyzed. Based on the data analyzed, one or more failures within the parking mechanism may be determined and an alert may be sent.
