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 device for a handle of a motor vehicle door. The device includes, integrated into the door, a primary module that supplies power by inductive coupling to a secondary module integrated into the handle. The primary module includes a primary coil and the secondary module having a secondary coil positioned facing the primary coil. The secondary coil also serves as a repeater for contactless communication between the primary module and a terminal. If the handle is retractable, the device also allows the position of the handle during its movement between a deployed position and a retracted position to be estimated.

A control arrangement for a motor vehicle door supplied with electrical power from a motor vehicle on-board network and including a lock with an electric opening drive for the motorized opening of the motor vehicle lock. The control arrangement has a door control unit for controlling the opening drive and changes from a normal operating mode to an emergency operating mode in response to a predetermined emergency situation. The control arrangement has a power transmission unit, configured to, responsive to the door control unit changing from the normal operating mode to the emergency operating mode, wirelessly receive electric power from a first mobile device and provide the electric power to the door control unit so that the opening drive opens the lock.
