In known devices for motor vehicles for opening and / or closing a door or a flap locking locks are unlocked by triggering a proximity sensor and / or transferred handle elements of actuating handle for manually opening a door or flap from a retracted to an extended state.

Such devices are for example off WO 2014/049026 and US 2011/0148575 known.

A disadvantage of the prior art, when the battery of a motor vehicle was emptied, neither the locking locks unlocked nor the handle elements for manual opening of doors or flaps can be transferred to the extended state. Consequently, it will be impossible for the user of the motor vehicle to gain access to the locked motor vehicle.

It is the object underlying the invention to propose an actuating handle for motor vehicles for opening and / or closing of a door or a flap, which overcomes the problems known from the prior art and access to the vehicle regardless of the power supply or independent of ensures a deflated condition of a vehicle battery.

This object is achieved by the subject matter having the features of the independent claim. Advantageous embodiments of the invention are the subject of the figures, the description and the dependent claims.

According to one aspect of the invention, the object is achieved by an actuating handle for a motor vehicle for opening and / or closing a door or a flap with a gripping element, which between an operating position, in which the handle element for manually opening a door or a flap in an extended Condition is arranged, and a locking position in which the handle member is arranged in a retracted state, is movable and a voltmeter for particular continuous determination of an applied operating voltage, wherein upon detection of a below a predetermined detected voltage value by the voltmeter, the actuating handle is formed is to transfer the handle member from the locking position to the operating position. As a result, for example, the technical advantage is achieved that the access to the vehicle for a driver is guaranteed regardless of the power supply of the actuating handle. By detecting an undershooting of a critical voltage value, for example, shortly before reaching a complete discharge of a motor vehicle battery, at least the handle element of the driver's door of the motor vehicle is transferred to the operating position. Thus, it is possible for the driver or the user of a motor vehicle to get access to the vehicle despite a completely discharged state of the vehicle battery. Due to the fact that the actuating handle uses a remaining residual charge of the battery in order to transfer the gripping element into the actuation position by means of a drive, a user can nevertheless actuate the actuation handle.

In order to carry out the transfer of the grip element by simple mechanical means, the movement of the grip element from the locking position to the actuation position takes place about a pivot axis. This allows a cost-effective implementation and a reduced susceptibility to malfunction of the actuating handle, since in this regard can be made of known solutions.

In an advantageous embodiment, the actuating handle has a drive in order to transfer the grip element from the locking position into the actuating position. This results, for example, in the advantage that, in particular in connection with the transfer of the grip element from the locking position into the actuation position about a pivot axis, to existing drive solution can be used. Thus, a simple implementation with reduced susceptibility and proven means is also possible here.
In particular, in order to take into account aesthetic requirements, the grip element is received in the locking position in a trough and in another embodiment, the grip element is formed in the locking position flush with the door or the flap. This results, for example, the additional advantage that the handle element and devices located underneath are protected in the locked position against contamination during driving.

In a further advantageous embodiment, the actuating handle has a lighting means. This results, for example, the advantage that a lighting of the apron or the area in front of the door or the flap is possible. By the transfer of the handle element and thus also the lighting means, which can be arranged in particular directly on the handle element in the operating position, the lighting of the apron or the area in front of the door or the flap is additionally improved.

In a particular embodiment, the lighting means is concealed in the locking position of the grip element. This results, for example, the advantage that no light can penetrate to the outside in the locking position and the light source can be additionally or even better protected against contamination and mechanical effects.

In a further particular embodiment, the lighting means is designed to indicate an open or a closed state of the door or the flap in the actuation position of the handle element. Additionally or alternatively, the illuminant may indicate a battery state of charge of a motor vehicle. This results, for example, the advantage that in addition to the immediate determination of an open or locked state, especially in battery-powered electric vehicles is immediately apparent, which state of charge the vehicle or its battery. Thus, this information is already available to the user of the motor vehicle at a time when he is still in front of or outside the vehicle.

In an advantageous embodiment, the actuating handle on a lock cylinder, which is in the locking position by the handle element cover. This results, for example, in the advantage that, in the event of a defect or a deflated battery, the lock cylinder arranged below the grip element is accessible.

In order to be able to arrange the voltmeter directly on the voltage sensor, the actuating handle has a proximity sensor, wherein the voltmeter is designed to detect a drop below a predetermined voltage value of an operating voltage applied to the proximity sensor. As a result, the voltmeter can be arranged, for example, with the sensor on a circuit board.

In an advantageous embodiment, the actuating handle is designed to transfer upon detection of an undershooting of a predetermined detected voltage value by the voltmeter, handle elements of all doors or flaps of a motor vehicle from the locking position to the operating position. This results, for example, the advantage that the access to the vehicle for a driver is independent of the power supply of the actuating handle not only on the driver's door but also on any other door or flap of the motor vehicle is guaranteed.

According to a further aspect of the invention, the object is achieved by a method for operating an actuating handle for a motor vehicle for opening and / or closing a door or a flap with a handle element, which between an actuating position in which the handle element for manually opening a door or a flap is arranged in an extended state, and a locking position, in which the grip element is arranged in a retracted state, is designed to be movable and a voltmeter for particular continuous determination of an applied operating voltage, the method comprising the steps, in particular continuous measurement of the applied operating voltage and transferring the grip element from the locking position to the actuation position when falling below a predetermined applied operating voltage. This results, for example, the advantage that the Access to the vehicle for a driver is ensured regardless of the power supply of the actuating handle. By detecting an undershooting of a critical voltage value, for example, shortly before reaching a complete discharge of a motor vehicle battery, at least the handle element of the driver's door of the motor vehicle is transferred to the actuation position. Thus, it is possible for the driver or the user of a motor vehicle to get access to the vehicle despite a completely discharged state of the vehicle battery. Due to the fact that the actuating handle uses a remaining residual charge of the battery in order to transfer the gripping element into the actuation position by means of a drive, a user can nevertheless actuate the actuation handle.

In an advantageous embodiment, grip elements of all doors or flaps of a motor vehicle are transferred from the locking position into the actuation position. This results, for example, the advantage that the access to the vehicle for a driver is independent of the power supply of the actuating handle not only on the driver's door but also on any other door or flap of the motor vehicle is guaranteed.

Fig. 1 shows a schematic representation of an actuating handle 100 for a motor vehicle for opening and / or closing a door or a flap 103 in the locking position. The grip element 101 has a rectangular basic shape and is received in a rectangular depression 105. The grip element 101 is received in the depression 105 in such a way that the grip element 101 is formed flush with a door or a flap 103 on which the actuation handle is arranged. The grip element 101 is delimited by surrounding grip element limiting sections, which are arranged opposite one another in the locked state or in the state of the grip element 101 accommodated in the depression 105. Alternatively, the handle member 101 and the corresponding trough 105 may have any other shape and is not limited to the illustrated shape. For example, an oval or a curved shape of the grip element 101 would also be conceivable.

Fig. 2 shows a schematic representation of an actuating handle 100 for a motor vehicle for opening and / or closing a door or a flap 103 in the operating position. In the actuated position, the handle member 101 is operably arranged to manually open a door or flap 103. In the illustrated embodiment, the handle member 101 is formed about a pivot axis from the locking position to the actuated position. This can be realized, for example, with an electric drive, which can be actuated by triggering sensors on the outer surface of the actuating handle 100 or of the grip element 101, by actuating a remote control or a distance sensor.

At the Griffelementbegrenzungsabschnitten illuminants 201 are at least partially arranged. In the present embodiment, the lighting means 201 is formed as a continuous light strip, wherein the light strip along the Griffelementbegrenzungsabschnitte extends in a circumferential direction of the handle member 101. The continuous light strip can be formed for example by a plurality of LEDs or an alternative light source, wherein the continuous light strip has a substantially central arrangement on the handle element boundary sections in a depth direction. This simplifies that the lighting means is better protected in the locking position and can penetrate less light from the bulb to the outside. Preferably, the lighting means 201 is adapted to be in the Actuating position of the handle member 101 to indicate an open or a closed state of the door or the flap 103. For example, this can be realized by lighting the bulb 201 in different colors. It would be conceivable in this case to indicate an opened state of the door or the flap 103 by green illumination of the illuminant, while a closed state of the door or the flap can be indicated by red illumination of the illuminant 201. Alternatively or additionally, the lighting means 201 is designed to realize a battery state of charge of a motor vehicle and / or illumination of the apron or the area in front of the door or the flap 103 in the actuation position of the handle element 101. This is particularly important in the application of a battery-powered motor vehicle of particular importance.

In addition, the actuating handle 100 has a lock cylinder 203, which is in the locking position by the handle member 101 top. By pivoting the handle member 101 in the operating position of the lock cylinder 203 is exposed and can be operated manually with a key. The transfer of the handle member 101 from the locking position to the actuating position is effected by pivoting by a drive about a pivot axis. Alternatively, however, the transfer can also take place translationally, rotationally or by a mixed form of movements.

Fig. 3 1 shows a schematic illustration of a circuit diagram of an actuating handle 100 with a sensor 303 and a voltmeter 301 with evaluation unit 305. The voltmeter 301 can measure an operating voltage applied to the sensor 303 and ascertain, with the aid of the evaluation unit 305, that the sensor 303 falls below a predetermined voltage value. The measuring of the applied operating voltage can be done either continuously or at defined time intervals. Alternatively or additionally, the operating voltage could also be measured and evaluated on a drive for transferring the grip element 101 from the locking position into the actuation position or directly on a battery of the motor vehicle. It is only essential that upon detection of a fall below a predetermined voltage value by the voltmeter 301 or by the evaluation unit 305 directly the transfer of the grip element 101 in the Actuated by the drive, since the battery could be directly before a complete discharge state.

The invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a number of variants is conceivable, which makes use of the illustrated solution even with fundamentally different types of use.
