Abstract: A closure latch assembly, operable in one of a normal operating mode and an emergency mode, has a power release motor, a ratchet and a pawl, with the ratchet being moveable between a striker capture position and a striker release position and the pawl being moveable between a ratchet holding position, whereat ratchet is maintained in the striker capture position, and a ratchet release position, whereat ratchet is biased toward the striker release position. The power release motor is configured to operate using primary control signals received from a primary controller external to closure latch assembly during the normal operating mode of closure latch assembly and to operate using secondary control signals received from a secondary controller internal to closure latch assembly during the emergency operating mode of closure latch assembly and not operate using the secondary control signals received from secondary controller during the normal operating mode.

Abstract: A latch assembly for a motor vehicle includes a latch mechanism, a power-operated latch release mechanism, and an over-center spring-biased reset mechanism. The power-operated latch release mechanism is operable during a power release operation to shift the reset mechanism from a first over-center operating state into a second over-center operating state.

Abstract: A latch assembly for a closure panel of a vehicle includes a power release actuator, a pawl, a ratchet, and a multi-stage geartrain. The multi-stage geartrain includes a first compound gear and a second sector gear in meshed engagement with the compound gear. The sector gear includes an arm extending radially therefrom. In a rest position, a gap is defined between the arm and a cam surface of a pawl. Actuation of the power release actuator actuates the multi-stage geartrain and pivots the arm through the gap and into contact with the pawl. During pivoting through the gap, inertia is increased and the arm contacts the pawl with an impulse force. Continued rotation of the arm causes further rotation of the pawl and release of the ratchet. The arm is disposed within an axial height defined by the multi-stage geartrain, and torque applied to the arm increases during rotation.

Abstract: A closure latch assembly for a motor vehicle closure panel is equipped with a common kinematic chain of components for a latch release mechanism utilizing a first range of handle travel to initiate a power release of a latch mechanism and further utilizing a second range of handle travel to initiate a mechanical release of the latch mechanism. An actuation rod may include a magnet that, when moved out of range of a sensor, signals to initiate the power release. In the event that the power release does not occur, further movement of the actuation rod forces the mechanical release. In both the power release and mechanical release, a pawl is rotated from a ratchet holding position to a ratchet release position.

Abstract: A power closure latch assembly with a manually actuatable release and reset feature is provided. The release feature allows the latch assembly to be mechanically released from within a cabin of the vehicle such that a vehicle closure panel can be opened, while the reset feature allows the latch assembly to be manually and mechanically reset from within the cabin of the vehicle to allow the vehicle closure panel to be closed and latched.
