Description

The invention relates to a bicycle having at least two wheels. The invention further relates to a method of operating the bicycle.Bicycles are generally known that can be driven by an electric machine in addition to the driving power of a user. Such bicycles are also known as electric bicycles, pedelec or e-bikes. A driving power of the user is generally supported by the electric machine in accordance with a user's request and a torque fed in by the user. The electric machine can be arranged as a central motor in the region of the pedal crankshaft or as a wheel drive directly on the respective drive wheel. A bicycle is therefore to be understood as meaning not only a classic bicycle that can be driven exclusively with muscle power without a motor, but also a bicycle with a motor. In particular, the term "bicycle" is also to be understood as meaning load wheels having three or more wheels. The bicycle is a vehicle that can be used by at least one user, in particular a rider.Furthermore, WO 2016 000 911 A1 discloses a method in which vehicle information about a vehicle, in particular about a rail vehicle, is output by means of an output device, wherein the output device is smart glasses having an output unit which outputs the vehicle information. The smart glasses are worn on the head of a user.The object of the present invention is to improve a bicycle. In particular, the functional scope of the bicycle as well as the safety and operating comfort for the user of the bicycle should be increased. The object is achieved with a bicycle according to claim 1 and by a method according to claim 8. Embodiments are subject of the dependent claims.A bicycle according to the invention comprises at least one transmitter, at least one receiver and smart glasses, wherein the at least one transmitter is signal-transmittingly connected to the at least one receiver integrated in the smart glasses in order to visualize data provided by the transmitter at least in a field of vision of a user during a bicycle operation.The bicycle comprises in particular a drive train and at least two wheels. For example, the bicycle comprises the usual components of a muscle-powered bicycle. In particular, the bicycle comprises an electric machine designed as a drive motor, which is integrated in the drive train of the bicycle in order to reduce the load on the user during the movement or to increase its range, specifically as a function of the capacity of an energy store connected thereto. The drive motor can be arranged as a central motor in the region of the pedal crankshaft or as a wheel drive directly on a drive wheel.For example, the at least one transmitter is integrated in a device of the bicycle. Alternatively or additionally, the at least one transmitter is integrated on an external device located in the vicinity of the bicycle. As a result, data can be transmitted from the respective transmitter to the at least one receiver in the smart glasses. For bidirectional data transmission, it is proposed that not only a receiver but also a transmitter be integrated in the smart glasses, wherein not only a transmitter but also a receiver is then integrated on a device of the bicycle and / or on a device located in the environment of the bicycle.The smart glasses are configured to be worn on the head of the user and comprise at least one display unit which visualizes the data provided by the transmitter for the user, so that the user does not have to take his gaze from the roadway. This not only increases safety during operation of the bicycle, but also increases user comfort at the same time. In particular, the functional scope of the bicycle is also extended as a result. According to one embodiment, the smart glasses are integrated in a helmet. For example, the smart glasses are designed as a sight for a helmet. Preferably, the visor can be opened and closed.The data visualized by smart glasses in the user's field of vision may be the same data visualized on a screen of an onboard computer of the bicycle mounted on a handlebar. For example, the at least one transmitter is connected in a signal-transmitting manner to means for ascertaining data during a bicycle operation. As means for ascertaining data, it is possible to use both devices or elements, in particular sensors of a sensor system, which, for example, acquire, in particular sense, measurement data on the bicycle, on the user and / or from the environment, and methods or algorithms, which, for example, ascertain, in particular calculate, data during a bicycle operation from operating data of the bicycle or with the aid of additionally provided information. The invention thus includes the technical teaching that the ascertainment of data can be sensed directly or calculated indirectly from further information, wherein this data is transmitted via the transmitter to the receiver of the smart glasses, independently of how it is ascertained, in order to be visualized in a field of vision of the user.Optionally, the smart glasses can generate not only optical signals, in particular pictorial representations, but also acoustic and / or haptic signals for the user via means integrated therein. For example, a loudspeaker can be integrated in the smart glasses in order to output acoustic signals. For example, a microphone can be integrated in the smart glasses in order to record acoustic signals. For example, vibration-generating means can be integrated in the smart glasses in order to generate haptic signals. For example, the user can be warned of driving situations which are dangerous for safety by means of acoustic and / or haptic signals. A combination of loudspeaker and microphone on the smart glasses can be used as a hands-free device for telephone calling, in particular for coupling to a mobile telephone.According to one embodiment, the bicycle further comprises at least one data processing unit, wherein the at least one data processing unit is arranged in front of the at least one transmitter and / or behind the at least one receiver in a signal-transmitting manner. In other words, data are first processed, in particular evaluated, in a data processing unit before they are transmitted to the receiver via the transmitter. Alternatively or additionally, received data are processed, in particular evaluated, in a data processing unit. The at least one data processing unit can be integrated both in the smart glasses and on a device of the bicycle or on an external device located in the vicinity of the bicycle.According to one embodiment, the smart glasses are connected at least indirectly or directly to at least one external device located in the vicinity of the bicycle in a signal-transmitting manner. The external device may be, for example, a smartphone, a smart watch, or another device that can ascertain and / or transmit data.

For example, at least two operating modes are provided, namely a city mode for visualizing at least one speed of the bicycle, a battery range of the bicycle and a drive power of a drive motor of the bicycle, and a training mode for visualizing at least one pulse of the user, a care and a power of the user. In addition, an operating mode can be provided which simulates a competition and superimposes on a known, i.e. stored route, at least times for route sections and a speed of the bicycle. For this purpose, GPS means are also provided in order to detect the location of the bicycle. The user can preferably configure the operating modes, in particular the type and number of representations in the respective operating mode.According to one specific embodiment, during bicycle operation, the smart glasses visualize environment information, route information, vehicle information, user information, training information and / or recommendations in a field of vision of the user. The environmental information can comprise a temperature, a distance to a preceding vehicle, a relative speed to a preceding vehicle, a slope and / or a height. The route information can comprise a setpoint travel direction, in particular visualized by a compass display and / or a sky direction, an imminent action, in particular a change of direction, preferably with a distance and / or an anticipated travel duration until the action, a previous travel duration, an anticipated remaining duration, a distance covered and / or remaining as well as height meters covered and / or remaining. The vehicle information can comprise an actual speed, an actual direction of travel, in particular visualized by a compass display and / or a sky direction, a gear and / or a transmission ratio of the drive train, an engine power, a braking power, a state of charge of a battery, a battery health state, an acceleration, an angular speed and / or an angular acceleration. The user information may include a heart rate, a heart rate, a driver torque, and / or a driver's performance. The driver power is, for example, the product of the carcass and the driver torque. The training information may include a target heart rate range, a target performance range, and / or a target carcass. The recommendations may include information about a target gear and / or a carcass. For example, the recommendation can be visualized to increase or decrease a gait and / or to increase or decrease the carcass.For example, the data memory is integrated in the smart glasses. Preferably, a data processing unit is arranged in a signal-transmitting manner between the smart glasses and the data memory. Preferably, not only different operating modes but also environmental information, route information, vehicle information, user information, training information and / or recommendations are stored on the data memory. For example, the data memory is integrated in the data processing unit. Alternatively or additionally, a data memory can be used on an external device which is connected to the data processing unit in a signal-transmitting manner.The data processing unit functions as a control unit or control device and is designed to evaluate data and to generate at least optical, optionally also acoustic and / or haptic signals via the smart glasses as a function of these data. In particular, the data processing unit has a signal interface for a signal-transmitting connection, wherein the signal location has a transmitter and a receiver for bidirectional signal transmission. For example, the signal-transmitting connection can be configured to be wired, wireless or optical.A signal-transmitting connection is a communicating connection in which data, in particular measurement data, and / or information are transmitted as a signal from a transmitter to a receiver. The signals may be, for example, switching, control, data transmission or command signals. For example, the data processing unit can be a group of control units or control units. For example, one of the control units can be part of a drive machine, a transmission or another device of the bicycle. The data processing unit can be arranged on the handlebar, in the region of the transmission, in the region of the drive machine or at another point of the bicycle, for example on the frame. Alternatively, the data processing unit may be arranged outside the bicycle.A signal interface is a connection for exchanging data and signals between various components of the bicycle and other devices external to the bicycle. The respective signal interface enables at least two components or units to communicate with one another. The respective signal interface is integrated into the respective component or integral part thereof and serves for receiving and transmitting signals. For example, the smart glasses have a signal interface which is connected to a signal interface on the data processing unit in a signal-transmitting manner. For example, an external device located in the vicinity of the bicycle has a signal interface which is connected to a signal interface on the data processing unit in a signal-transmitting manner. In particular, the data processing unit receives data and information on the environment, the route, the bicycle, the user, the training and / or recommendations for operating the bicycle at the signal interface of sensors and / or devices connected thereto in a signal-transmitting manner and transmits these data and information, if appropriate after an evaluation, in particular after a linkage, to the smart glasses, where they are then visualized for the user in order to inform the latter.According to one embodiment, the smart glasses have at least one operating element for user input. The user can control the smart glasses by input via the at least one operating element and navigate through a menu, for example, and make a selection. In particular, the operating element is designed as a mechanical button or button. Alternatively or additionally, the operating element is designed as a touch-sensitive region on the smart glasses. For example, at least one device on the bicycle, for example a drive motor or a transmission, can be controlled via the respective operating element. For example, at least one external device, for example a smartphone, located in the vicinity of the bicycle can be controlled via the respective operating element.According to one embodiment, the smart glasses have means for eye control functions. Eye control functions, also called eye tracking functions, detect where the user is looking, wherein the user performs user inputs by means of a gaze, in particular via eye movements, and can navigate through a menu, for example, and make a selection.In a method according to the invention for operating a bicycle according to the invention, i.e. a bicycle having at least one transmitter and smart glasses having at least one receiver, the at least one transmitter transmits data to the at least one receiver in the smart glasses during operation of the bicycle, wherein these data are visualized by the smart glasses in a field of vision of the user. The selection of the data visualized during the bicycle operation is preferably carried out as a function of a driving situation and / or an operating mode. In particular, an automatic change between the display of different data takes place. For example, automatic reduction of the number of data is performed at high speeds and / or at rough terrain to avoid information flooding and to improve the concentration of the user by focusing on essential information. For example, the reduction takes place to a maximum of four to seven items of information shown. Preferably, the user can configure the type and number of representations, in particular set threshold values and conditions that cause a change of representations.
