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: An electronic control circuit with a backup energy source subassembly for an e-latch assembly and a method of operating the backup energy source subassembly are disclosed. The electronic control circuit includes a control unit including a computing module and a memory for electrically coupling to a plurality of sensors and to a main power source. The backup energy source subassembly is electrically coupled to the control unit for providing electrical energy to the electronic control circuit in response to one of a failure and interruption of the main power source. An output module is electrically connected to the backup energy source subassembly and to the main power source for driving an actuation group. The backup energy source subassembly includes a backup low voltage source and a boost-buck converter configured to selectively supply voltage to and selectively amplify voltage from the backup low voltage source.

Abstract: An electronic latch for a motor vehicle closure system with an electronic control circuit including a handle switch reading circuit for a two-pin handle switch and a method of operating the handle switch reading circuit are disclosed. The electronic control circuit includes a control unit. The handle switch reading circuit is controlled by the control unit for coupling with a handle switch subassembly. The handle switch reading circuit is adapted to supply an AC voltage to the handle switch subassembly and produce an output voltage waveform corresponding to the charging and discharging of a handle capacitor of the handle switch subassembly and in response to a handle switch of the handle switch subassembly being operated. The handle switch reading circuit determines a position of the handle switch and presence of faults in the handle switch reading circuit and the handle switch subassembly based on the output voltage waveform.

Abstract: A latch assembly for a closure panel of a motor vehicle and corresponding method of operation are provided. The latch assembly includes a latch housing for attachment to the closure panel and contains an actuation group to latch and unlatch the closure panel. An electronic control circuit that has a latch controller is disposed within the latch housing and is coupled to the at least one actuation group. The electronic control circuit includes a motor voltage and current sensing circuit for sensing a motor current and a motor voltage of a remote electric motor disposed remotely from the latch housing. The latch controller monitors and controls the actuation group and determine at least one of a motor rotational position and a motor speed of the remote electric motor based on at least one of the motor current signal and the motor voltage signal and controls the remote electric motor accordingly.

Abstract: A touch pad for operating an e-latch assembly of a motor vehicle entry system that includes a control circuit with a backup energy source and method of operating the entry system are provided. The touch pad includes a touch pad controller in communication with the control circuit of the e-latch assembly. The touch pad also includes at least one entry input sensor coupled to the touch pad controller for outputting a signal indicative of a touch to operate the e-latch assembly. The touch pad further includes a mechanical emergency switch assembly adjacent the at least one entry input sensor and including a plurality of pins electrically coupled to the control circuit for operating the e-latch assembly when the at least one input sensor is not operable due to one of a power loss and malfunction of the at least one input sensor.
