Description

The invention relates to a method for setting a position of a first vehicle part with respect to a second vehicle part. The invention furthermore relates to a vehicle having at least one sill and at least one lighting device integrated into the sill.In modern vehicles, ambient lighting devices are used in door sills below vehicle doors in order to generate a radiation-shaped light carpet on both sides of the vehicle.Such environmental lighting devices are known from DE 10 2013 211 877 A1 and DE 10 2020 106 299 A1.DE 10 2018 114 500 A1 discloses a body component for a vehicle, the position of which relative to a neighbouring component is adjusted with the aid of an adjusting element. In order to secure this relative position between the body component and the adjacent component in the final set position, an additional securing element is inserted into a through-opening of the setting element, wherein the setting element and the securing element have a relatively flat thread pitch.DE 10 2017 007 847 B4 discloses a lighting device for an underbody of a vehicle, which is screwed to a sill of the vehicle via sheet metal brackets with bore holes.Furthermore, DE 10 2015 220 911 A1 discloses a surrounding lighting device arranged in a sill below doors of a vehicle, having a projection module which is held on the sill via a holding device. In order to compensate for manufacturing tolerances, an adjustment device can be provided, with which the position of the projection module relative to a light shaft can be adjusted within predetermined limits manually and optionally also automatically via corresponding actuators.To adjust the light propagation of the light carpet, the inclination of the ambient lighting device is changed by means of an adjustment screw. For this purpose, the adjusting screw is rotated with the aid of a screwing robot. The screw rotor is provided with an adjustment bit in the form of an external hexagon which engages with an internal hexagon of the adjustment screw. After the light carpet has been adjusted, when the adjustment bit is pulled out, there is the risk that the mechanical prestress between the adjustment bit of the screwing robot and the adjustment screw will be released on account of a small tolerance band. This slightly resets the adjusting screw. However, even in the case of a slight mechanical change, such as the adjustment path, the mechanical-photometric translation results in a large photometric deviation of the light projection on the ground, which leads to poor adjustment of the light carpet.The object of the present invention is to provide a method and a vehicle which enable improved position adjustment of a vehicle part with respect to a second vehicle part.To achieve the object, a method having the features of claim 1 and a vehicle having the features of claim 8 are proposed.Advantageous embodiments of the method are the subject of the dependent claims.According to a first aspect, a method for setting a position of a first vehicle part with respect to a second vehicle part is proposed. In the method, a preset position of the first vehicle part is set with respect to the second vehicle part. Subsequently, an adjusting means abutting the first vehicle part is operated by means of an adjusting device in order to adjust a target position of the first vehicle part with respect to the second vehicle part. Finally, a vibration is generated at the adjusting means by means of the adjusting device.By generating a vibration at the adjusting means, a tension between the adjusting element and the adjusting device is released, so that a tension-free adjustment takes place and a subsequent removal of the adjusting device is possible.The first vehicle part and / or the second vehicle part can be an exterior part for a vehicle. Thus, the first vehicle part can be a lighting device and the second vehicle part can be a sill. The lighting device can be inserted into a recess of the sill.Advantageously, a position of the first vehicle part is adjusted with respect to the second vehicle part by tilting the first vehicle part about a tilting axis which is parallel to a transverse axis of the vehicle, wherein the first vehicle part is tilted in the direction of a vertical axis of the vehicle.The adjustment element can be a screw element or a pin element. If the adjusting means is a screw element, then the screw element can be screwed into the second vehicle part for adjusting a position of the first vehicle part with respect to the second vehicle. The adjusting device may be a robot having a means for operating the adjusting element.The preset position is advantageously that position in which the first vehicle part is positioned relative to the second vehicle part in such a way that by actuation of the setting element a position of the first vehicle part relative to the second vehicle part can be changed to a desired position.The desired position advantageously corresponds to an end position of the first vehicle part.The vibration can be generated by the adjusting device moving the adjusting means. For this purpose, the adjusting device can move the adjusting means linearly and / or rotationally.In an advantageous embodiment, the vibration is carried out by changing the direction of rotation of the adjusting device. The changes in the direction of rotation correspond to a shaking between the adjusting device and the adjusting element, so that a tension with respect to the adjusting device and the adjusting means is thereby reduced. The adjusting device advantageously carries out a minimum change in the direction of rotation, that is to say short changing rotary movements.In an advantageous embodiment, the steps, according to which an adjusting means bearing against the first vehicle part is actuated by means of an adjusting device in order to adjust a desired position of the first vehicle part with respect to the second vehicle part, and according to which a vibration is generated by means of the adjusting device at the adjusting means, are repeated. By the renewed actuation of the adjusting means, readjustment and thus fine adjustment of the desired position takes place. During the readjustment, the tension between the setting device and the setting element increases again. This is almost completely reduced by the subsequent vibration of the adjusting element. Consequently, by approximating, i.e. repeating the steps of actuating a setting means abutting the first vehicle part by means of a setting device to set a target position of the first vehicle part with respect to the second vehicle part and generating a vibration by means of the setting device at the setting means, the target position of the first vehicle part with respect to the second vehicle part can be set exactly.In an advantageous embodiment, after the step, according to which a vibration is generated at the setting means by means of the setting device, photometric monitoring of the set desired position is carried out. By means of the photometric control, it is possible to check whether the set setpoint state of the first vehicle part is okay. For photometric monitoring, a camera and analysis software, which is stored on a data processing device, such as a computer, connected to the camera, can be used. The evaluation software can determine, on the basis of a recording of the camera, whether the set desired state of the first vehicle part is okay.In an advantageous embodiment, the adjusting means is a screw element which abuts the first vehicle part and which is screwed into the second vehicle part in order to adjust a position of the first vehicle part with respect to the second vehicle part. The screw member may include a threaded portion and a head portion having an internal hexagon. The screwing-in device can have a means which engages in a positively locking and / or non-positively locking manner in the hexagon socket in order to screw the screw element into the second vehicle part and in order to generate a vibration by means of a minimum change in the direction of rotation. The head portion advantageously bears against the first vehicle part, wherein the threaded portion extends through an opening of the first vehicle part and can be screwed into an internal thread of the second vehicle part.In an advantageous embodiment, the adjusting device is a screwing robot with an adjusting bit. The adjustment bit advantageously has an external hexagon which engages in a form-fitting manner in an internal hexagon of the adjustment means in order to actuate the same, in particular to screw in and / or rotate it.In an advantageous embodiment, the first vehicle part is a lighting device for lighting a floor and the second vehicle part is a sill. Advantageously, the lighting device generates a radiation-shaped light carpet onto a ground on one side of the vehicle. For this purpose, the lighting device can have a plurality of lighting means, such as LED lamps, for example. The lighting device is advantageously used in the sill under a vehicle door, in particular in a front region of the sill as viewed in the vehicle direction. Advantageously, a lighting device is inserted into the door sills on both sides of the vehicle. The illumination device can also be referred to herein as an environmental or environmental illumination device or device.According to a further aspect, a vehicle is proposed which has at least one sill and at least one lighting device integrated into the sill, wherein a position of the lighting device in relation to the sill is set by means of a method according to the invention.A vehicle, a method for setting a position of a lighting device in relation to a sill, and further features and advantages are described in more detail below on the basis of an exemplary embodiment which is schematically illustrated in the figures. The following shows: FIG. 1 shows a schematic illustration of a vehicle having a sill and a lighting device integrated in the sill for producing a light carpet; and FIG. 2 is an enlarged view showing setting of a target position of the lighting device with respect to the rocker panel by a screw robot.In FIG. 1, a vehicle 10 is shown that has an internal combustion engine, not shown, and / or an electric motor, not shown. The vehicle 10 has a second vehicle part 14 arranged below a vehicle door 12 and a first vehicle part 16 inserted in the second vehicle part 14.The second vehicle part 14 is a side sill 18 and the first vehicle part 14 is a lighting device 20 inserted into the side sill 18.As can be seen in FIG. 1, the lighting device 20 generates a radiation-shaped light carpet 22 on a floor 24 to one side of the vehicle 10.In order to adjust a light propagation of the light carpet 22, an inclination of the lighting device 20 with respect to the sill 18 is changed. Specifically, the lighting device 20 is pivoted about a pivot axis 21 that corresponds to a Y axis and that is parallel to a vehicle lateral axis. As a result, a position of the lighting device 20 changes in a direction of a Z axis corresponding to a vehicle vertical axis.The inclination is varied by means of an adjusting means 26. The adjusting means 26 is a screw element 28, which is screwed into the sill 18, in particular into an internal thread, not shown, of the sill 18. The screw element 28 has a head portion 30 with an internal hexagon 32 and a threaded portion 34.As can be seen in FIG. 2, the head section 30 bears against the lighting device 20 and the threaded section 34 extends through a through-opening 36 made in the lighting device 20 in order to be screwed into the internal thread, not shown, of the sill 18. By screwing in the screw element 28, the lighting device 20 is pivoted about the pivot axis 21, so that the position of the lighting device 20 changes in the Z direction.The position, in particular the inclination, of the lighting device 20 is adjusted with the aid of an adjusting device 38. the adjusting device 38 is a screwing robot 40, which is provided on the end side with an adjusting bit 42 with an external hexagonal portion, which engages in a positive-locking manner in the internal hexagonal portion 32 of the head portion 30 in order to screw the screw element 28 into the internal thread, not shown, of the door sill 18.A possible method for adjusting the inclination of the illumination device 20 and thus of the light carpet 22 is described below. To adjust the inclination of the light carpet 22, the lighting device 20 is inserted into a recess of the sill 18 and adjusted to a defined preset position. The screwing robot 40 then travels to the lighting device 20 and inserts the setting bit 42 into the hexagon socket 32 and screws the screwing element 28 to the sill 18 until the lighting device 20 has reached a predefined desired position. After reaching the desired position, the screwing robot 40 performs a vibration movement by minimal change of the direction of rotation of the adjustment bit 42. As a result, a bracing between the adjustment bit 42 and the screw element 28 is reduced, so that a subsequent removal of the adjustment bit 42 from the screw element 28 is possible, so that a bracing-free adjustment of the lighting device 20 and thus of the light carpet 22 is achieved. Thereafter, photometric monitoring of the setting of the lighting device is carried out, for example, by recording the light carpet 22 produced on the floor 24 by means of a camera, not shown, and evaluating it by means of evaluation software stored on a data processing device, such as a computer. The evaluation software can determine on the basis of the camera recordings whether the setting of the illumination device 20 and thus of the light carpet 22 is okay. If the adjustment is not in order, readjustment can be carried out by slightly screwing in and subsequently vibrating the screw element 28 again by minimal change of the direction of rotation of the adjustment bit 42 and also rephotometric checking.In addition, after the first vibration of the screw element 28 by the screw robot 40, a subsequent fine adjustment of the desired position of the lighting device 20 can be carried out by slightly screwing the screw element 28 into the sill 18 and thus slightly increasing the clamping. The screwing robot 40 then performs a vibration movement again by means of a minimum change in the direction of rotation of the setting bit 42. As a result, a clamping relative to the adjustment bit 42 and the screw element 28 is reduced or completely released. This can be repeated until the optimum setting of the illumination device 20 and thus of the light carpet has been achieved. Thus, by approximating screwing and subsequently vibrating, the light carpet 22 can be optimally adjusted.The method for adjusting the lighting device 20 and thus the light carpet 22 is characterized by the non-subsequent removal of the adjustment bit 42 from the screw element 28 and the non-bracing adjustment of the lighting device 20. This is achieved in that the screwing robot 40 performs vibration movements on the screwing element 28 by means of a minimum change in the direction of rotation.List of reference characters10 Vehicle 12 Vehicle door 14 Second vehicle part 16 First vehicle part 18 Rocker 20 Lighting device 21 Pivot axis 22 Light carpet 24 Floor 26 Adjusting means 28 Screw element 30 Head portion 32 Hexagon socket 34 Threaded portion 36 Through opening 38 Adjusting device 40 Screw robot 42 Adjusting bit
