Description

Locking of motor vehicle door locks Technical Field The present invention relates to the locking of a motor vehicle door or another movable closure member of a vehicle. The invention relates in particular to a motor vehicle door lock, a motor vehicle lock module, a motor vehicle door module and a method for locking a motor vehicle door. Background In vehicles, door locks that can be opened from the outside and from the inside are used, for example by means of a handle. In addition to purely manual door locks, electric motor vehicle door locks are used, in which the lock mechanism is actuated, for example, by an integrated motor. Depending on the concept of the lock, it may be necessary to ensure that the door lock is not inadvertently opened. In the case of a power door lock, this can be achieved, for example, by suitable control, and in the case of a mechanical door lock, for example, decoupling of the actuating lever can ensure that the locking pawl is not actuated. However, it has turned out that there is still a need for solutions that are as efficient and easy to implement as possible. Summary of The Invention It is therefore an object of the present invention to provide an improved locking device for a motor vehicle door lock in this respect. This object is achieved by the subject matter of the independent claims. Further examples are given in the dependent claims. The aspects described below also apply to the motor vehicle door lock, the motor vehicle lock module, the motor vehicle door module and the method for locking a motor vehicle door and vice versa. Furthermore, features which are not explicitly mentioned can also be freely combined with one another. According to the present invention, there is provided a motor vehicle door lock. A motor vehicle door lock includes a locking mechanism having a rotary latch and a locking pawl, a locking pawl driver, and a locking device for locking the pawl driver. The rotary latch can be blocked in the direction of the open position by the locking pawl in at least one main latch. The locking pawl is movable with the locking pawl driver from a locking position to a release position to release the rotary latch from the main latch in the direction of the open position. The locking pawl driver has a force introducing element for connection to the actuating means for introducing a release force for actuating the locking pawl. The force introduction element may be blocked by the locking means to prevent the pawl from being released. The blocking of the force introduction element may for example be used as a locking device during driving, for example as a child safety device. The blocking of the force introduction element represents an effective solution for the temporary locking of the door lock. For example, the locking device only selectively engages the path of movement of the force introduction element without modifying the locking mechanism or the force transmission. For example, the blocking of the force introduction element may be provided as a double lock function. According to one example, the force introduction element is a linear force transmission element, which is movable in an actuation direction for transmitting a release force and in an opposite return direction. A seat for the locking means is formed on the linear force transmission element. The locking means comprises a movable locking element movable between a release position and a locking position. The locking element blocks the abutment in the locking position in the actuation direction. The linear force transmission element together with the abutment and the locking element constitute a reliable and easy to realize locking of the lock. According to one example, the locking device comprises a driver by means of which the locking element can be moved from the release position to the locking position. The driver is for example constructed integrally with the lock or arranged separately and is connected to the locking element by means of a force transmission element. According to one example, a lock housing is provided. The locking element is supported on the lock housing at least in the locked position when the force transmitting element is actuated. The support on the lock housing makes possible a simple transfer of force, so that the locking can be constructed correspondingly more simply. According to one example, the locking element comprises a groove formed by two edge segments. In the locked position, the edge section laterally encloses the linear force transmission element and supports the linear force transmission element on at least two sides transverse to the longitudinal direction of the linear force transmission element. The groove results in a stable and at the same time compact force transmission to the abutment for locking purposes. According to one example, at least one of the group comprising the abutment and the locking element comprises a force limiting device, such that when the
