Abstract: A vehicle door with a variable latching function which holds the vehicle door in a desired latched position by applying a latching torque using a controllable damper is described. An evaluation and control unit detects the desired latched positions by evaluating an instantaneous door movement sensed by a sensor system and actuates the damper using an actuator element. The evaluation and control unit releases the latched position after a corresponding activation is detected. The variable latching function acts on the vehicle door within a functional region which extends to a predefined opening region between a first opening angle and a maximum opening angle when the vehicle door drops below a predefined speed or comes to a standstill within the functional region.

Abstract: A vehicle door has an easy exit feature that holds the vehicle door in a desired latched position by applying a latching torque with a controllable damper. An evaluation and control unit detects the desired latched positions by evaluating an instantaneous door movement sensed by a sensor system, and accordingly actuates the damper. The evaluation and control unit releases the latched position after a corresponding activation has been detected. The easy exit feature is embodied as a variable latching function, and applies a maximum holding force to the vehicle door by way of the damper and locks the vehicle door in the desired latched position.
