A method of deactivating a secondary lock feature of a vehicle includes sensing a movement of an interior door handle, and determining a status of the secondary lock feature to ascertain whether the secondary lock feature is active. The method includes starting a timer to measure an elapsed time since sensing the movement of the interior door handle, sensing an environmental condition of an interior passenger compartment of the vehicle with a sensor, and setting an unlock delay time based on the environmental condition. When the secondary lock feature is disposed in an active state and the elapsed time period is greater than or equal to the unlock delay time, the method includes automatically generating a control signal to thereby deactivate the secondary lock feature.

A method of controlling a vehicle includes sensing movement of an interior door handle, sensing a position of a vehicle door after movement of the interior door handle is sensed to determine if the door remains in an unopened position or if the door moves into an opened position after movement of the interior door handle is sensed. When movement of the interior door handle is sensed, a timer is started to determine if the measured time period is equal to or greater than a maximum delay time. A active or inactive state of a double door lock feature of the door lock system is determined and a control signal to automatically generated to deactivate the double door lock feature if the double door lock feature is active, the measured time period is equal to or greater than the maximum delay time, and the door is in the unopened position.

A vehicle including a first detection unit, a second detection unit, and a processor is disclosed. The first detection unit may be configured to detect presence of an occupant inside the vehicle. The second detection unit may be configured to detect that the vehicle may be in a double-lock mode. The processor may be configured to obtain inputs from the first detection unit and the second detection unit. Responsive to obtaining the inputs, the processor may determine that a predetermined condition is met. The predetermined condition may be met when the occupant may be present inside the vehicle and the vehicle may be in the double-lock mode. The processor may be further configured to output a notification comprising instructions for the occupant to perform a predetermined action responsive to a determination that the predetermined condition is met to enable the vehicle to exit the double-lock mode.

The invention relates to a motor vehicle door closure, comprising a locking mechanism, an electric drive (3, 4) for the locking mechanism, and a child-restraint element (14) with a corresponding sensor (15). The electric drive (3, 4) can be activated or deactivated in order to open the locking mechanism dependant on the position of the child-restraint element (14), said position being requested using the sensor (15). The activated child-restraint element (14) can be deactivated in an emergency operation by a switch (17), and the locking mechanism can be opened by the electric drive (3, 4).
