[0002] A known device for automatically correcting the orientation of a motor vehicle headlight beam is known from DE 37 43 137 C2. In addition, DE 198 17 594 C2 discloses a headlight stabilization system. In addition, a holding device for a headlight is known from DE 10 2019 123 312 B3. Summary of the invention

[0003] The object of the present invention is to create a power train and a method for operating a holding device of a power train, such that a particularly advantageous operation of the power train is possible.

[0004] This object is achieved according to the invention by a motor vehicle having the features of claim 1, by a motor vehicle having the features of claim 2 and by a method having the features of claim 10. Advantageous embodiments of the invention are the subject matter of the dependent claims.

[0005] A first aspect of the present invention relates to a power vehicle, which can be configured as a motorcycle in particular. The power vehicle has a headlight that can illuminate at least a partial area of ​​the surroundings of the power vehicle. This means that the headlight can provide light and emit light to or into the surroundings to thereby illuminate at least a partial area of ​​the surroundings. The headlight is held on a frame of the power vehicle, also referred to as a frame or configured as a frame, via a universal suspension device of a holding device of the power vehicle. The holding device includes a drive device and the universal suspension device. The universal suspension device allows the headlight to pivot relative to the frame around at least two or exactly two pivot axes extending perpendicularly to each other. In other words, by holding the headlight on the frame via the universal suspension device, the headlight can pivot relative to the frame not only around the first pivot axis but also around the second pivot axis, and each pivot axis extends perpendicularly to each other. This means that the headlight can perform a first pivoting movement relative to the frame around the first pivot axis, and the headlight can perform a second pivoting movement relative to the frame around the second pivot axis. In other words, the headlight can be rotatably moved, i.e. turned, not only about the first pivot axis but also about the second pivot axis. For example, the first pivot axis extends in the longitudinal direction of the power vehicle, also referred to as the vehicle, and is therefore parallel to the longitudinal direction of the vehicle, or the first pivot axis extends, for example, in the transverse direction of the vehicle, and is therefore parallel to the transverse direction of the vehicle, or the first pivot axis extends in the vertical direction of the vehicle, and is therefore parallel to the vertical direction of the vehicle. The longitudinal direction of the vehicle is also designated by x or is referred to as the x-direction, the transverse direction of the vehicle is also designated by y or is referred to as the y-direction, and the vertical direction of the vehicle is also designated by z or is referred to as the z-direction. The second pivot axis extends, for example, in the transverse direction of the vehicle, and is therefore parallel to the transverse direction of the vehicle, or in the vertical direction of the vehicle, and is therefore parallel to the vertical direction of the vehicle, in particular when the first pivot axis extends in the longitudinal direction of the vehicle or is parallel to the longitudinal direction of the vehicle. The second pivot axis extends, for example, in the longitudinal direction of the vehicle, and therefore parallel to the longitudinal direction of the vehicle, or in the vertical direction of the vehicle, or parallel to the vertical direction of the vehicle, in particular when the first pivot axis extends in the transverse direction of the vehicle, or parallel to the transverse direction of the vehicle. For example, the second pivot axis extends in the longitudinal direction of the vehicle, or parallel to the longitudinal direction of the vehicle, or in the transverse direction of the vehicle, or parallel to the transverse direction of the vehicle, in particular when the first pivot axis extends in the vertical direction of the vehicle, or parallel to the vertical direction of the vehicle.

[0006] For example, the pitching movement of the power vehicle about the vehicle transverse direction and the rolling movement about the vehicle longitudinal direction can be compensated by the gimbal suspension, or the pitching movement of the power vehicle and the yaw movement about the vehicle vertical direction can be compensated by the gimbal suspension, or the yaw movement and the yaw movement of the power vehicle can be compensated by the gimbal suspension. It is particularly understood here that, for example, when the frame performs a pitching movement and / or a rolling movement and / or a yaw movement from the corresponding initial position of the frame and the headlight and thus moves out of the initial position of the frame, the headlight maintains its initial position or moves only slightly, that is, moves less out of the initial position of the headlight than the frame moves out of the initial position of the frame. Due to the gimbal suspension, the headlight thus does not perform or only slightly or without the frame performing a strong pitching and / or rolling and / or yaw movement, so that despite the pitching and / or rolling and / or yaw movement, the surroundings can still be particularly advantageously illuminated by the headlight. This ensures that the power vehicle is particularly safe and thus advantageously operated.

[0007] In order to now enable a particularly advantageous and, in particular, particularly safe operation of the motor vehicle, the drive device is designed to provide a force and / or a torque and to apply it to the cardanic suspension device in order to thereby counteract a corresponding pivoting movement of a headlight, for example, in the form of a headlight, about a corresponding pivot axis and thus brake the corresponding pivoting movement. Excessive overswing can thereby be prevented. This is to be understood in particular as follows: if, for example, the vehicle frame performs such a movement that the frame moves out of its initial position, the headlight performs a pivoting movement relative to the frame about at least one of the pivot axes, in particular in such a way that, despite the movement of the frame out of its initial position, the headlight remains in its initial position or does not move strongly out of its initial position without the frame moving out of its initial position. This means that the above-mentioned movement of the frame can be compensated or compensated. For example, the gimbal suspension and the headlight held thereon form a system or a component of a system which, due to the gimbal suspension, is autonomously or independently, in particular always leveled in its center of gravity, that is to say, aligned or maintained in its center of gravity, and preferably only by the action of gravity. This means that, for example, despite the movement of the vehicle frame out of its initial position, the light cone provided or provided by the headlight for illuminating at least part of the surroundings remains at least and therefore remains stable. The frame moves out of the initial position of the frame, for example, due to the following reasons, that is, the power vehicle is accelerated or braked or performs a turning when the power vehicle is driving and is thus placed in a curve by the female or male driver of the power vehicle or the frame performs a yaw movement. For example, due to the acceleration and braking of the power vehicle, the power vehicle, in particular the frame, undergoes a pitching movement. Therefore, the headlight performs a pivoting movement relative to the frame in a direction of movement, especially relative to a predetermined or predeterminable reference system, during its corresponding pivoting movement. Since the drive device is now configured to provide the force and / or the torque and apply it to the universal suspension device and thereby resist the corresponding pivoting movement, especially in this direction of movement, it is possible to avoid the headlight from moving too far in this direction of movement. Therefore, it is possible to avoid that when the frame moves out of its initial position, the headlight moves too far away from its initial position. The drive device and the universal suspension device form a universal joint, also called a universal joint system, through which undesirable and excessive movement of the headlight can be avoided when the frame moves out of its initial position, especially from its initial position. As a result, an advantageous light distribution of the light that can be provided or provided by the headlight and that is used to illuminate at least the sub-area can be ensured both in the initial position of the vehicle frame and in positions of the vehicle frame that differ from the initial position of the vehicle frame, thereby ensuring a particularly safe and advantageous operation. In particular, the gimbal system makes it possible for the above-described system consisting of the gimbal suspension device and the headlight fastened thereto to always remain or be leveled in its center of gravity, even if and during, for example, a movement of the vehicle frame out of its initial position.

[0008] For example, the power vehicle has at least one or exactly one inertial measurement unit, or the power vehicle has, for example, a plurality of inertial measurement units. The corresponding inertial measurement unit is also referred to as an IMU (intertial measurement unit). For example, the corresponding inertial measurement unit can detect at least one measurement variable, which describes the corresponding orientation or position of the frame, in particular around the vertical direction of the vehicle and / or the longitudinal direction of the vehicle and / or the transverse direction of the vehicle. For example, the corresponding inertial measurement unit can provide a corresponding measurement signal, in particular an electrical measurement signal, which describes, i.e., characterizes the corresponding variable detected by means of the corresponding inertial measurement unit, in particular at least one value of the corresponding measurement variable detected by means of the corresponding inertial measurement unit. It is particularly conceivable here that the drive device is controlled and thus operated, in particular open-loop controlled or closed-loop controlled, according to the signal and thus according to the measurement variable detected by means of the corresponding inertial measurement unit, in particular so as to thereby provide a force or torque and apply it to the universal suspension device and thereby resist the corresponding pivoting movement, thereby braking the corresponding pivoting movement. As a result, for example, the center of gravity of the system and / or the center of gravity of the headlight can always remain at or in the same position during and despite a movement of the frame and thereby a movement out of its initial position.

[0009] A second aspect of the present invention relates to a power vehicle having at least one headlight configured to illuminate at least a portion of the surrounding area of ​​the power vehicle, the headlight being retained on the frame of the power vehicle via a retaining device having a drive device and a universal suspension device, the universal suspension device allowing the headlight to pivot about at least two pivot axes extending perpendicularly to each other and relative to the frame.

[0010] In order to achieve a particularly safe and thus advantageous operation of the power vehicle, it is provided in a second aspect of the invention that the power vehicle has at least one surroundings camera configured to detect at least one area of ​​the surroundings, which is held on the frame via a holding device and can thus be pivoted with the headlight relative to the frame about a pivot axis. Thus, the gimbal suspension has a dual function. On the one hand, the gimbal suspension is used to hold the headlight on the frame and thus compensate for the movement of the frame or the power vehicle in terms of the orientation or position of the headlight, so that the headlight is particularly always retained in its initial position, for example despite the movement of the frame from its initial position and during the movement of the frame from its initial position. On the other hand, the gimbal suspension is simultaneously used to avoid excessive movement of the surroundings camera with the frame also in terms of the surroundings camera. Therefore, despite the possible movement of the frame, not only the headlight but also the surroundings camera, which is also referred to as a camera, always remains in its initial position. Therefore, at least the partial area of ​​the surroundings can be advantageously illuminated by means of the headlight, and therefore this area of ​​the surroundings can be particularly advantageously detected by means of the camera. Thus, a particularly safe and thus advantageous operation of the power vehicle can be ensured. Advantages and advantageous embodiments of the first aspect of the invention may be regarded as advantages and advantageous embodiments of the second aspect of the invention, and vice versa.

[0011] In order to enable particularly safe and thus advantageous operation of the power vehicle, it is provided in one embodiment of the second aspect of the invention that the drive device is designed to provide a force and / or a torque and apply it to the universal suspension device in order to thereby counteract the corresponding pivoting movements of the headlights and the surroundings camera about the corresponding pivot axes and thereby brake the corresponding pivoting movements.

[0012] Another embodiment of the second aspect of the invention is characterized in that the surroundings camera is held on the headlight and thus via the headlight on the gimbaled suspension, that is to say is coupled to the gimbaled suspension. This makes it possible in a particularly advantageous manner with regard to installation space, weight and costs to ensure that both the headlight and the surroundings camera always remain in their initial position, in particular even if the vehicle frame moves out of its initial position, for example due to pitch and / or roll and / or yaw movements.

[0013] In another particularly advantageous embodiment of the first and second aspects of the invention, it is provided that the gimbal suspension also allows a pivoting movement of the headlight about a third pivot axis extending perpendicularly to the pivot axis and relative to the vehicle frame. Thus, for example, a first pivot axis therein extends in the longitudinal direction of the vehicle, a second pivot axis therein extends in the transverse direction of the vehicle and a third pivot axis therein extends in the vertical direction of the vehicle, wherein the pivot axes extend perpendicularly to one another in pairs. Thus, not only pitching movements but also rolling movements and also yaw movements of the vehicle frame can be compensated for by means of the gimbal suspension, so that despite possible pitching and / or yaw and / or rolling movements of the vehicle frame, the headlight and thus, for example, also the surrounding camera remain in their initial position. This ensures that the power vehicle can be operated particularly safely and therefore advantageously.

[0014] It has proven to be particularly advantageous if the drive is also designed to counteract and thus brake the respective pivoting movement about the third pivot axis by exerting a force and / or a torque on the universal joint. Excessive over-swinging about the three pivot axes can thereby be avoided, so that particularly advantageous operation is possible.

[0015] In order to enable particularly safe operation, it is provided in a further embodiment of the invention that the light is designed as a headlight.

[0016] In another particularly advantageous embodiment of the invention, the power vehicle is a single-track vehicle with exactly two wheels, so that the power vehicle is preferably a single-track motorcycle with exactly two wheels. One of the wheels is the front wheel, and the other wheel is the rear wheel, which is arranged behind the front wheel in the longitudinal direction of the vehicle. The wheels are ground-contacting elements, which are rotatably held on the frame. Via the ground-contacting elements, the power vehicle can be supported or supported on the ground downward in the vertical direction of the vehicle. If the power vehicle is driven along the ground, while the power vehicle is supported on the ground downward in the vertical direction of the power vehicle via the ground-contacting elements, the wheels roll on the ground, in particular directly on the ground.

[0017] Finally, it has been shown to be particularly advantageous that the motor vehicle is a three-wheeled vehicle with exactly three wheels, so that, for example, the motor vehicle is a three-wheeled vehicle. In addition, it is conceivable that the motor vehicle is a motorcycle with a sidecar.

[0018] A third aspect of the present invention relates to a method for operating a holding device of a power vehicle, in particular a power vehicle according to the first aspect of the present invention. In the method according to the third aspect of the present invention, the power vehicle has at least one headlight configured to illuminate at least a portion of the surrounding area of ​​the power vehicle, which headlight is held on the frame of the power vehicle via the holding device of the power vehicle. The holding device includes a drive device and a universal suspension device, which allows the headlight to pivot about at least two pivot axes extending perpendicular to each other and relative to the frame.

[0019] In order to now enable particularly safe and therefore particularly advantageous operation of the power vehicle, it is provided in a third aspect of the invention that a force and / or a torque is provided by means of the drive device and applied to the universal joint suspension device, thereby counteracting the corresponding pivoting movement about the corresponding pivot axis and thus braking the corresponding pivoting movement.

[0020] Advantages and advantageous embodiments of the first and second aspects of the present invention may be regarded as advantages and advantageous embodiments of the third aspect of the present invention, and vice versa.

[0021] Therefore, the invention provides that the drive device does not drive or does not only drive the universal joint to compensate for the movement of the frame and keep the headlight in its initial position, but the drive device resists the corresponding pivoting movement to brake the corresponding pivoting movement and thus avoid overswing around the corresponding pivot axis.

[0034] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0035] Figure 1 A motor vehicle 1, also referred to as a vehicle, is shown in a schematic front view, which in the exemplary embodiment shown in the figure is designed as a single-track motorcycle with exactly two wheels. Figure 1 One of the wheels can be seen in the figure and is denoted by 2. The motor vehicle 1 has a frame 3, which is also called a frame or is designed as a frame. Figure 1 The wheel 2 that can be seen in the figure is the front wheel of the power car 1, and the power car 1 is Figure 1 The wheels that cannot be seen are rear wheels. For example, a drive engine is held on the frame 3, by means of which, for example, at least one or exactly one wheel, in particular the rear wheel, can be driven, so as to drive the power vehicle 1 as a whole. Figure 1 The power vehicle 1 (the vehicle transverse direction of which is indicated by the double arrow 4) is at least indirectly held on the frame 3 so as to be rotatable relative to the frame 3 about the corresponding wheel rotation axis. The power vehicle 1 (the vehicle transverse direction of which is indicated by the double arrow 5) has, for example, a handlebar 6, which can be operated by a female or male driver of the power vehicle 1 and thereby pivoted together with the wheel 2 relative to the frame 3 and thereby steered, so as to thereby, for example, enable the power vehicle 1 to turn. The power vehicle 1 (the vehicle longitudinal direction of which is indicated by the double arrow 7 and is perpendicular to Figure 1 The drawing plane extends) also has a lighting 8, which is Figure 1 In the embodiment shown, it is designed as a headlight. Light, in particular light in the form of a light cone, can be provided by means of the headlight 8 in order to thereby illuminate at least a sub-region of the surroundings 9 of the motor vehicle 1 .

[0036] Depend on Figures 2 to 7It can be seen that the headlight 8 is held on the vehicle frame 3 via a holding device 10. For this purpose, for example, the holding device 10 is connected to the headlight 8, in particular to its headlight housing 11, on the one hand, and to the vehicle frame 3 on the other hand. The holding device 10 has a gimbal suspension device 12, via which the headlight 8 is held on the vehicle frame 3, in particular in such a way that the gimbal suspension device 12 is connected to the headlight 8, in particular to its headlight housing 11, on the one hand, and to the vehicle frame 3 on the other hand. The gimbal suspension device 12 allows the headlight 8 to perform a pivoting movement relative to the vehicle frame 3 about three, in particular exactly three pivot axes extending perpendicularly to each other. The first pivot axis extends parallel to the longitudinal direction of the vehicle, which is also designated by x or is referred to as the x-direction. The second pivot axis extends parallel to the transverse direction of the vehicle, which is also designated by y or is referred to as the y-direction. The third pivot axis extends parallel to the vertical direction of the vehicle, which is also designated by z or is referred to as the z-direction. Furthermore, the holding device 10 has a drive device 13 which in the present case has at least two or exactly two electric motors, namely a first electric motor 14 and a second electric motor 15. For example, the respective electric motors 14, 15 are designed as brushless direct current motors.

[0037] Erke 3

[0038] In order to ensure that the motor vehicle 1 is now particularly safe and thus advantageously operated, the drive device 13 is designed to provide a force and / or a corresponding torque, in particular a torque acting about a corresponding pivot axis, and to apply it to the universal suspension 12 in order to thereby counteract a corresponding pivoting movement of the headlight 8, for example, designed as a headlight, about a corresponding pivot axis and thus brake the corresponding pivoting movement. The first pivot axis can be Figure 3 The second pivot axis can be seen from Figure 2 and is indicated by 17, and the third pivot axis can be Figure 3 Seen in and marked with 18.

[0039] Figure 1 and 2 The frame 3 and the headlight (headlight 8) are shown in the corresponding initial positions. The initial position of the headlight 8 is also Figure 2 and 3 Shown in.

[0040] If, for example, the motor vehicle 1 is driven along the above-mentioned ground and braked here, the frame 3 performs a pitching movement about the vehicle transverse direction, due to which the headlight 8 is pivoted about the pivot axis 17 relative to the frame 3, so as to thereby keep the headlight 8 in the initial position of the headlight 8, such as from Figure 4 As can be seen in FIG. 1 , the frame 3 moves out of the initial position of the frame 3 due to the pitching motion. Therefore, Figure 4The headlight 8 is shown at the time of the pitching movement of the vehicle frame 3. It can be seen that despite the pitching movement of the vehicle frame 3, the headlight 8 is still in its initial position.

[0041] If, for example, the motor vehicle 1 is traveling along the ground and is accelerated in the process, the frame 3 executes a second pitching movement about the vehicle transverse direction. Figure 5 The headlight 8 is shown at the time of the second pitching movement. During the second pitching movement and despite the second pitching movement, the headlight 8 remains in the initial position of the headlight 8 due to the gimbal suspension 12. During the corresponding pitching movement, the headlight 8 is prevented from over-swinging by means of the drive 13, in particular by means of the motor 15, because the motor 15 counteracts the pivoting movement of the headlight 8 about the pivot axis 17.

[0042] Figure 6 For example, the lighting 8 is shown at the moment of the first yaw and roll movement of the vehicle frame 3, and Figure 7 For example, the lighting 8 is shown at the moment of the second yaw and roll movement of the frame 3. For example, Figure 8 The first yaw and roll motions of the frame 3 are shown, and Fig. 9 A second yaw and roll movement of the frame 3 is shown. Due to the counteracting of the corresponding pivoting movement of the headlight 8 about the corresponding pivot axis by the universal suspension 12 and by the drive 13, in particular the electric motor 14, during the corresponding yaw and roll movement, the headlight 8 remains in its initial position despite and during the corresponding yaw and roll movement of the frame 3, thereby ensuring a particularly advantageous illumination of the surroundings 9.

[0043] Fig. 9 A first rolling movement of the frame 3 is shown. Fig.10 The second rolling movement of the frame 3 is shown. It can be seen that the first and second rolling movements can also be compensated by means of the universal suspension 12 and by means of the drive 13, respectively, so that the headlight 8 does not also carry out the corresponding rolling movement of the frame 3, but remains in its initial position, in particular remains aligned or leveled in its center of gravity.

[0044] Depend on Figure 2 and 4It can be seen that the motor vehicle 1 has, for example, an environment camera 19, also referred to as a camera for short, which is held on the headlight 8 and thus on the gimbal 12 via the headlight 8. The environment camera 19 can therefore be pivoted together with the headlight 8 about the pivot axes 16, 17 and 18 relative to the vehicle frame 3, so that despite and during yaw and / or roll and / or pitch movements of the vehicle frame 3, the environment camera 19 remains in its initial position. As a result, the environment 9, i.e. at least one region of the environment 9, can always be detected particularly advantageously with the aid of the environment camera 19.
