These variables are detected by means of physical or chemical effects and transformed as sensor data into an electrical signal that can be processed further.Sensors include optical sensors, for example camera, lidar, radar, TOF and further sensor technologies, for example acoustic sensors.Computer program products typically comprise a sequence of instructions which, when the program is loaded, cause the hardware to perform a specific method which leads to a specific result.A bicycle handlebar is a component of a bicycle that serves to steer and control the bicycle. Hereinafter, a bicycle handlebar is also referred to for short as a handlebar.A bicycle handlebar includes various components such as a front handlebar, the connection between the handlebar and the fork of the bicycle, handlebar handles for allowing the rider to hold the handlebar, handlebar tube to which the handles are attached, brake and shift levers. There are various types of links including straight links, curved links (racing links), crawler links, etc.A handlebar position is a configuration of one or more length, height, width and / or angle adjustment capabilities of a handlebar. A target steering position is a position to be set, that is, a desired position in the immediate future.The term translatory element comprises a plurality of mechanisms that enable translatory movements, such as rails, sliding slides, linear guides, sliding bearings and sliding elements, as well as other constructions that allow a rectilinear displacement in the form of a forced movement.A joint is a mechanical connection between two bodies that allows relative movement. It enables a rotational or pivoting movement about one or more axes.In this patent application, an axis is an imaginary line.In this patent application, a handlebar movement is a movement of the handlebar that serves to change the position of the handlebar, rather than changing a steering direction of the bicycle. The term steering handle movement also includes inward and outward movements of a component of the steering handle, for example steering handle handles. Retracting and extending movements of a handlebar or of handlebar handles can be executed symmetrically or asymmetrically, for example in order to compensate for an asymmetric posture of the cyclist.A longitudinal axis of a bicycle extends in the vehicle length direction, from front to rear. It is perpendicular to the roadway and passes through the center of the bicycle. This axis is related to movements that move the bicycle forward or backward, such as accelerating or braking. A bicycle has many longitudinal axes.A height axis of a bicycle extends laterally and is perpendicular to the longitudinal axis. Steering movements rotate a bicycle about a vertical axis. A bicycle has many axles.A transverse axis is perpendicular to the longitudinal and vertical axes. It lies in the horizontal plane and influences movements such as lateral balancing and tilting of the bicycle. A rotation about a transverse axis is called pitching.A "state" refers to the overall status, individual sizes, or characteristic of a system at a particular time. It comprises a series of parameters, qualitative and / or quantitative properties or variables which together describe the current state or the situation of the system.The basic idea of the invention is to set the position of a bicycle handlebar based on sensor data relating to a state. For the position adjustment of the bicycle handlebar, at least two possibilities are provided for a forced movement of the bicycle handlebar, namely a rotational movement about a transverse axis of a bicycle by means of a lockable joint, as well as a first translatory movement of a component of the handlebar by means of at least one first lockable translatory element along a transverse axis. Both the joint and the first translatory element are each assigned a drive for the electrified execution of the respective movement.Since the criteria or the requirements according to which the position of a bicycle handlebar is to be adjusted are manifold, conceivable sensors or conceivable combinations of sensors for detecting one or more states are manifold.It is thus ensured that a setpoint position of a bicycle handlebar is determined based on sensor data, and the handlebar position is set by means of the first and second drive in such a way that the determined setpoint position is reached as well as possible without an interaction by a human being being being required for changing the handlebar position.It is understood that it is also conceivable to determine a desired change in the position of the bicycle handlebar instead of a desired position of the bicycle handlebar.Advantageous embodiments and refinements emerge from the further dependent claims and from the description with reference to the figures of the drawing.According to a preferred development of the invention, the bicycle handlebar comprises a lockable second translatory element, which enables a second translatory movement of the handlebar with at least a portion along a vertical axis of the bicycle, and a third drive for electrified execution of the second translatory movement, wherein the third drive has an interface to an energy storage device.Accordingly, a method for setting a handlebar position, wherein the list is selected from the at least one component, further comprises a lockable second translatory element, which enables a second translatory movement of the handlebar, wherein the second translatory movement comprises at least a portion along a vertical axis of the bicycle and the handlebar movement is carried out by means of a first, second and / or third drive.Thus, a greater freedom of movement of the bicycle handlebar can be ensured by the bicycle handlebar being movable along a vertical axis and the width of the handlebar being adjustable along a transverse axis of the bicycle. It is understood that the translatory movements along the vertical axis or the transverse axis do not have to run exclusively along a vertical axis or transverse axis, but that translations which have both a portion along a transverse axis and along a longitudinal axis and / or a vertical axis are also conceivable.According to a preferred development of the invention, the second translatory movement comprises a further portion along a longitudinal axis of the bicycle.Accordingly, the second translatory movement is a movement along a straight line which results from a linear combination of a vertical axis and a longitudinal axis of the bicycle.According to a preferred development of the invention, the state depending on which a handlebar movement is carried out is contained in the following list: inclination of a ground; posture of a cyclist; speed of the bicycle; position, in particular GPS position, of the bicycle; acceleration of the bicycle.Accordingly, it is conceivable to adjust the handlebar position of a bicycle to the inclination of a ground that changes during travel during travel.Furthermore, it is also conceivable to move the bicycle handlebar again and again during a journey, and to take into account the posture of a cyclist when dimensioning the movement to be carried out by the handlebar, in order to prevent an immobile upper body of a cyclist during a longer journey. It is also conceivable to adjust the handlebar position of a bicycle in such a way that the cyclist is assisted to assume an aerodynamic posture, in particular at higher speeds. For example, the influence of a cyclist's posture on aerodynamics at low speeds is negligible.Alternatively or additionally, it is advantageous if the bicycle handlebar is positioned at low speeds and / or steep track sections in such a way that optimal force transmission from the cyclist to the pedals of a bicycle is ensured. It is understood that the mentioned variables and states can be detected directly by means of a corresponding sensor system, or that the mentioned variables or states can also be taken from map data and / or GPS data if the corresponding states, such as the inclination of the underlying surface, the distance covered and the like, are stored in historical data with respect to an associated position.It is understood that it is advantageous if the steering handle position is also determined based on a user input, in particular based on a user preference.For example, it is conceivable that a user himself defines a driving style, for example, sport, performance-oriented or comfort-oriented. Alternatively or additionally, it is also conceivable that a user can input a desired change in position of a bicycle handlebar via a key input and the handlebar position is set based on the key input.Accordingly, it is also appropriate that, before starting a trip, the user inputs a route intended to travel with the next trip, and a change in the link position during the trip is set and set based on the route data of the route input.According to a preferred development of the invention, states on which the handlebar position is to be adjusted are repeatedly determined during a journey and the electrified execution of the movement of a position-changing component, i.e. the joint or a translatory element, of the bicycle handlebar is executed during the journey.Accordingly, it is conceivable, for example, for the posture of a cyclist to be checked repeatedly during a journey, for example at predetermined time intervals, and for the position of a bicycle handlebar to be adapted on the basis of the posture of the cyclist.A suitable sensor system for determining a posture of a cyclist is, for example, a camera. It is conceivable that the camera, which serves to check the posture of the cyclist, is part of a mobile terminal of the cyclist when the mobile terminal is positioned in a suitable device and the camera of the mobile terminal is at a suitable angle and at a suitable distance from the cyclist.It is understood that a data memory on which personalized historical data comprising one or more states and an associated handlebar position are stored is advantageous if the handlebar position has been determined by means of a method as described above.A computer program product according to a method of an embodiment of the invention executes the steps of a method according to the preceding description when the computer program product runs on a computer, in particular an in-vehicle computer. When the program in question is used on a computer, the computer program product causes an effect, namely the position setting of a handlebar.The present invention is explained in more detail below with reference to the exemplary embodiments indicated in the schematic figures of the drawings.
