Problems solved by technology

One problem with this switching strategy is that the switch communicates the same state (closed state and closed state) when the ratchet is in the first engaged position, and positions between the first and second engaged positions
This means that the controller cannot distinguish the partially closed state of the door from the open state, and therefore will not continue to power the tie down, resulting in tie down failure

Abstract

The invention discloses a latch assembly for a motor vehicle closure system. The latch assembly has a latch mechanism, a latch release mechanism and a power cinching mechanism. The latch mechanism isoperable in a released state when a closure panel is located in an open position, in a secondary closed state when the closure panel is located in a partially-closed position, and in a primary closedstate when the closure panel is located in a fully-closed position. The cinching mechanism interacts with the latch mechanism to establish the secondary closed state and is actuated for shifting the latch mechanism from its secondary closed state into its primary closed state.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit and priority of U.S. Provisional Application Serial No. 62 / 533,314, filed July 7, 2017. The entire disclosure of the aforementioned application is hereby incorporated by reference as if fully set forth. technical field [0003] The present disclosure generally relates to closure latch assemblies of the type used in vehicle closure systems for releasably securing a closure panel relative to a body portion of a motor vehicle. More specifically, the present disclosure relates to a power-operated closure latch assembly equipped with a roller-type latch mechanism and a latch-tightening mechanism configured to provide a power-tightening function. Background technique [0004] This section provides background information related to types of latch assemblies used in motor vehicle closure systems and is not necessarily prior art to the inventive concepts associated with the present disclosur...
