  • Patent number: 6863318
    Abstract: A latch of a vehicle door includes a retention plate having a shut face portion and a perpendicular inside face portion. The latch further includes a rotatable claw, a pawl resiliently biased into contact with the claw, and an intermediate release lever. The intermediate release lever has an axis of rotation substantially perpendicular to the axes of rotation of the claw and the pawl. During power release of the latch, a controller signals a power release actuator to rotate the intermediate release lever. The power release actuator is positioned in the plane of the inner face portion of the retention plate. As the intermediate release lever rotates, the cam surface of the intermediate release lever operatively rotates the pawl to disengage the claw and release the striker. If there is a failure of the power release mechanism, the mechanical linkage from the inside or outside door handle can be used to rotate the intermediate release lever and release the claw.

  • Publication number: 20030182863
    Abstract: A vehicle door latch control system detects latch malfunctions via a closed loop system that includes a first switch that is triggered by operation of a door handle and a second switch that indicates whether a latch is in a fully latched position. A controller monitors the operating states of the first and second switches and interprets these operating states to determine door and latch operation as well as detect a latch malfunction.
