Abstract
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.
Claims19
A control arrangement for use with a motor vehicle door, including a lock and an opening drive configured for providing motorized opening of the lock, wherein the lock comprises a locking mechanism of a lock latch and a locking pawl and wherein for the motorized opening of the motor vehicle lock, the opening drive is coupled to the locking pawl, so that the locking pawl can be lifted in a motorized manner by means of the opening drive, wherein when the control arrangement is in an assembled state, the control arrangement is supplied with electrical power from a motor vehicle on-board network, wherein the control arrangement is set up to receive electrical power from an interior of the motor vehicle, the control arrangement comprising:
- a door control unit configured to control the opening drive and change from a normal operating mode to an emergency operating mode in response to detecting an emergency;
- and
- 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 in the interior of the motor vehicle and provide the received electric power to the opening drive to open the lock, wherein the opening drive opens the lock by lifting the locking pawl without a user applying an actuation force to an inner door handle or an outer door handle of the motor vehicle door via a mechanical force chain.
A motor vehicle door comprising:
- a lock comprising a locking mechanism of a lock latch and a locking pawl;
- an opening drive coupled to the locking pawl, the opening drive configured to provide motorized opening of the lock so that the locking pawl can be lifted in a motorized manner by means of the opening drive;
- a door control unit configured to control the opening drive and change from a normal operating mode to an emergency operating mode in response to detecting an emergency, the door control unit being set up to receive electrical power from an interior of the motor vehicle;
- and
- 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 in the interior of the motor vehicle and provide the received electric power to the opening drive to open the lock, wherein the opening drive opens the lock by lifting the locking pawl without a user applying an actuation force to an inner door handle or an outer door handle of the motor vehicle door via a mechanical force chain.
A method of controlling a motor vehicle door including a lock and an opening drive configured to provide motorized opening of the lock, wherein the lock comprises a locking mechanism of a lock latch and a locking pawl and the opening drive is coupled to the locking pawl so that the locking pawl can be lifted in a motorized manner by means of the opening drive, and a controller configured to receive power from a vehicle on-board network and to receive electrical power from an interior of the motor vehicle, the method comprising:
- detecting, by the controller, an emergency situation;
- changing the controller from a normal operating mode to an emergency operating mode in response to the detecting step;
- providing electrical power wirelessly from a first mobile device in the interior of the motor vehicle to a power transmission unit;
- providing the received electrical power to opening drive;
- and
- opening, by the opening drive, the lock by lifting the locking pawl without a user applying an actuation force to an inner door handle or an outer door handle of the motor vehicle door via a mechanical force chain.
