Abstract:
1. A locking system for a motor vehicle door that includes internal trim that includes a handle groove that forms a cavity in the internal trim, the locking system comprising: a door lock that is alternately transferable into a locked position and an unlocked position; an internal actuation unit comprising: an internal actuation lever mounted facing the handle groove, wherein the internal actuation lever functions as a pickup that is mechanically linked to the door lock by a mechanical link between the pickup and the door lock, wherein the mechanical link is inactivated when the door lock is in the locked position and is operable when the door lock is in the unlocked position; a display that is coupled to the handle groove and that is configured to receive the pickup, the display configured to visually indicate an unlocking capability of the door lock as a function of the vehicle velocity, wherein the display comprises: a light emitting diode (LED) situated on a cheek of the handle groove opposite to the internal actuation lever, wherein the LED illuminates an area of the handle groove when a velocity of the motor vehicle is below a predefined limiting velocity, and the door lock is in the locked position and ready to be transferred into the unlocked position, and the sensor has not yet detected insertion of fingers; a detection unit situated on an outer side of the handle groove such that the detection unit directly adjoins the handle groove and is concealed under the internal trim; and a control unit coupled to the detection unit, wherein the detection unit is solely electronically coupled to the door lock through the control unit, and wherein the detection unit is mechanically decoupled from the door lock, wherein the detection unit is configured to: detect insertion of one or more fingers into the cavity in the internal trim; and generate, when insertion of one or more fingers into the cavity in the internal trim is detected, an unlocking signal, wherein the control unit is configured to: relay the unlocking signal to the door lock to transfer the door lock into the unlocked position only if the velocity of the motor vehicle is below the predefined limiting velocity, wherein the motor vehicle door is capable of being opened when a passenger pulls on the internal actuation lever and when: the door lock is in the unlocked position, the mechanical link is operable, and the velocity of the motor vehicle is below the predefined limiting velocity.
