A handle assembly for a closure of a vehicle includes a force-based sensor disposed beneath an uninterrupted class-A surface and responsive to a force applied thereto. The handle assembly includes a handle ECU, configured to monitor the force-based sensor and to communicate with an electronic latch controller. A super-capacitor is disposed on a PCB within the handle assembly for providing electrical power to the handle ECU and the force-based sensor. The handle ECU includes one or more feedback devices such as LED lights, acoustic, and haptic devices to provide information about the status of the closure and the electronic latch system. The handle assembly is also configured to provide different responses to two or more different levels of force applied to the force-based sensor. An output interface in the handle assembly provides wired and wireless backup communications to the electronic latch controller.

Smart handle assembly with force-based sensor and backup energy source

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.

Motor vehicle closure system with electronic latch and handle having two-pin handle switch

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.
