A door handle module for a movable part of a vehicle, in particular for a side door, tailgate, bonnet or luggage compartment hatch, comprising a handle support that can be mounted on the outer skin of the movable part, a handle mounted movably on the handle support and having an operating mechanism that can be hidden at least in part by the outer skin, the operating mechanism being operatively connectable to a latch or a latch drive so that an, in particular mechanical, operation of the latch of the movable part can be performed, and further comprising a sensor unit having at least one sensor element in order to detect a user intention in an operating region of a door handle depression of the movable part so that the lock or the latch drive is electrically actuatable in the operating region in the event that a user intention is identified.

A motor-driven door ratchet includes a catch part configured to lock a vehicle door to a vehicle body by being caught by a striker mounted on the vehicle body. A door locking and release part includes a main motor and is configured to allow the catch part to be locked or released from the striker. An inside emergency operation lever is connected to an inside handle installed in the vehicle door and is configured to be rotated by receiving a manipulation force to allow the vehicle door to be opened by applying torque to the catch part. An outside emergency operation lever is connected to an outside handle installed in the vehicle door and is configured to be rotated by receiving a manipulation force to allow the vehicle door to be opened by applying torque to the catch part.

A device for a handle able to be deployed in relation to a motor vehicle door. The device includes a primary module integrated into the door, supplying power, through inductive coupling, to a secondary module integrated into the handle and that moves in relation to the primary module along a predetermined path when the door handle moves between a deployed position and a retracted position. An advantageous arrangement of two primary coils of the primary module and of a secondary coil of the secondary module allows the device to estimate the position of the door handle. Furthermore, the device makes it possible to establish a wireless communication link between the primary module and the secondary module.

A mobile device wirelessly communicates with a vehicle device. The mobile device includes a receiving unit, a response signal generation unit, a transmission unit, a charging unit, and a charge state determination unit. The receiving unit receives a response request signal transmitted from the vehicle device. The response signal generation unit generates a response signal in response to the response request signal. The transmission unit transmits the response signal. The charging unit charges a built-in battery with an electric power supplied wirelessly or through wire from a power supply device. The charge state determination unit determines whether the charging unit charges the built-in battery. The mobile device is configured not to transmit the response signal, in a situation where the charge state determination unit determines that the charging unit is charging the built-in battery.

A motor-driven door latch for a vehicle includes a catch part which is caught on a striker mounted on the vehicle. A door locking and releasing part includes a main motor and applies torque to the catch part through the main motor to allow the catch part to be locked to or released from the striker. A motor-driven emergency door releasing part is provided with an auxiliary motor and is contacted with the door locking and releasing part. An inside emergency operating lever is connected with an inside handle installed at the door for the vehicle. An outside emergency operating lever is connected with an outside handle installed at the door for the vehicle. A manual emergency door release part is connected with the inside emergency operating lever.

A method and device for unlatching a door from a frame, using a keyless door latch system, is provided. In one embodiment, a secondary unlocking component receives a signal and derives power from the signal to provide a power source for the keyless door latch system. A microcontroller generates a control signal and an actuator, in response to receiving the control signal, actuates the secondary unlocking component, which allows an energy source, from an exterior of the door, to be transferred to the keyless door latch system for the unlatching of the door.

A motor-driven door latch includes a catch part that is caught on a striker to lock the vehicle door to the vehicle body or is released from the striker so that the vehicle door can be opened from the vehicle body. A door locking and releasing part includes a main motor and is configured to apply a torque to the catch part through the main motor. An emergency door releasing part is provided with an auxiliary motor and is contacted with the door locking and releasing part by operation of the auxiliary motor. An inside emergency operating lever is connected with an inside handle installed at the vehicle door and is configured to receive an operation force of the inside handle to rotate and apply torque to the catch part through the emergency door releasing part and the door locking and releasing part.
