Abstract
An electronic latch assembly for a closure device of a motor vehicle, having an actuator group operable for actuation of the closure device and an electric motor controllable to drive the actuator group (6). The electronic latch assembly has a backup energy source, and a control unit controlling the electric motor and the backup energy source to provide a backup supply voltage (Vsc) during an emergency operating condition. The control unit is configured to enter an emergency mode to cause disabling of actuation of the closure device, upon detecting the occurrence of the emergency operating condition, and to maintain disabled the actuation of the closure device, during the emergency operating condition.
