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.

An assembly for adjusting an adjustment element relative to a stationary portion of a vehicle, in particular of a vehicle door relative to a vehicle body comprises a drive motor for electromotively adjusting the adjustment element and an electrically actuatable locking device for locking the adjustment element with the stationary portion of the vehicle in a closed position, wherein the locking device has a locked condition in which the locking device is locked relative to the stationary portion for blocking the adjustment element in the closed position, and an unlocked condition in which the locking device is unlocked for adjusting the adjustment element relative to the stationary portion. A control device serves for controlling the drive motor and the locking device. It is provided that the control device is formed to actuate the drive motor for executing a diagnostic routine, while the locking device is in the locked condition.

A system for managing door operation of a vehicle includes a door system and a doorjamb system configured for the door to close against. The door system includes a door having a handle mechanism, an indicator mechanism coupled to the handle mechanism and actuated by motion of the handle mechanism, and a latch feature configured to be engaged for latching the door closed. The doorjamb system includes a sensor configured to generate a sensor signal indicative of a state of the indicator mechanism, and a latching mechanism configured to secure and release the latch feature of the door. Control circuitry of the vehicle is coupled to the sensor and latching mechanism, and is configured to receive the sensor signal, and control the latching mechanism based on the sensor signal. The control circuitry determines state information for the vehicle and determines whether to secure or release the latch mechanism.

An angle-detecting door handle assembly comprises: a handle member; a four-bar link configured to move the handle member between at least retracted and presented positions relative to a door surface; a motor configured to actuate the four-bar link; a rotary sensor configured to detect an angle of the four-bar link throughout actuation and generate a signal corresponding to the detected angle; and a controller configured to control the motor based on the signal from the rotary sensor.

The technology relates to assisting in the closing of a vehicle door by automatically pulling a door closed. One or more computing devices having one or more processors may receive, from one or more sensors, information indicating that a door on the vehicle is not closed. In response to the received information indicating that the door is not closed, the one or more computing devices may determine to send a triggering signal to close the door. The one or more computing devices may send the triggering signal to the actuator and the actuator may receive the triggering signal. In response to receiving the triggering signal the actuator may be activated to close the door of the vehicle without user input.

The invention relates to a motor vehicle door lock and to a method for electrically actuating a locking mechanism in said type of motor vehicle door lock. Said motor vehicle door lock comprises a locking mechanism and an electric drive (1, 2, 3) for the locking mechanism. It also comprises at least one signal transmitter (8) for impinging upon the electric drive (1, 2, 3). According to the invention, a first flank (F.sub.S) and also a second flank (F.sub.E) of a signal (S) generated by the signal generator (8) are evaluated for controlling the electric drive (1, 2, 3).
