ELECTRIC BICYCLE

Abstract

The disclosure relates to an electric bicycle. The electric bicycle comprises an electric motor for at least temporarily assisting or replacing a pedal operation. Assigned to the electric bicycle are at least two keys equipped with different rights, which differ from each other with respect to operating modes of the electric bicycle permitted in conjunction with a relevant key. One of the keys is an administrator key equipped with expanded rights. The expanded rights of the administrator key aids to provide a determination from a plurality of particular operating modes implementable for each of a remaining key from the at least two keys.

DETAILED DESCRIPTION

[0023] As required, detailed embodiments of the present disclosure are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the disclosure that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present disclosure.

[0024] In one embodiment of an electric bicycle according to the disclosure, which is described in what follows, at least two different keys are provided, in particular, wherein one of these keys is a key equipped with expanded rights (administrator key) and the other key is a key equipped with rights that are limited with respect to the administrator key (user key). In this case, the administrator key allows, in particular, programming of certain functions that can be utilized for the particular electric bicycle in conjunction with a certain user key.

[0025] The disclosure is not limited further with respect to the specific embodiment of these keys, wherein these can be, in particular, actual physical keys or wireless communication devices (e.g. on the basis of RFID, WLAN, near-field communication, etc.) or signals generated thereby.

[0026] FIG. 1 shows an exemplary database in a table, which contains different requirements stored for a plurality of keys (one administrator key and three different user keys in the example).

[0027] According to FIG. 1, specified for a user having the user identification (=ID) 49653 is a maximum speed of 30 km/h and a maximum speed for the electric motor assistance up to 25 km/h, wherein the driving light and a blind spot monitoring device must also be switched on at all times (symbolized by 1).

[0028] For a user having the user identification 51236, however, there is no requirement that the driving light be switched on (symbolized by 0), nor has a maximum vehicle speed been predetermined, wherein a limiting speed for the electric motor assistance of 25 km/h and permanently switched-on blind spot monitoring are also predetermined in this case.

[0029] The permanent activation of the blind spot monitoring also does not apply for the user having the user identification 65312, however, wherein the maximum speed for the electric motor assistance has been set to 20 km/h in this case.

[0030] The administrator key having the user identification 00001 therefore has expanded rights as compared to the user keys, since no limiting values are predetermined for the maximum vehicle speed or the electric motor assistance, wherein the driving light and blind spot monitoring may also be deactivated.

[0031] According to a first embodiment, which is schematically represented in FIGS. 2A-B, the contents of this database can be stored directly in the electric bicycle itself (e.g. with the use of a permanent memory).

[0032] FIG. 2A shows the configuration, by an administrator 21 having an administrator key 22 equipped with expanded rights, by means of a write access (indicated by an arrow 24) to the relevant database or the contents 23 assigned to the particular users. FIG. 2B shows the read-out (indicated by an arrow 27), by the user 25, of the corresponding user-specific settings or database entries 23 stored on the electric bicycle 28 with the use of a user key 26 equipped with rights that are limited as compared to the administrator key 22.

[0033] According to one further embodiment schematically represented in FIGS. 3A-B, the database or the contents 33a, 33b, 33c, assigned to the particular users can also be stored in a cloud memory 39, wherein the electric bicycle (labeled 38 in FIG. 3B) in this case is equipped with a device for wireless data transmission.

[0034] According to FIG. 3A, the establishment or configuration of the user-specific settings by an administrator 31 having an administrator key 32 equipped with expanded rights also takes place via a write access (indicated by an arrow 34) in this case, wherein the corresponding contents of the database are stored in the cloud memory 39 or on a cloud server. As soon as a certain user key (e.g. the user key of a user 35 labeled 36 in FIG. 3B) is inserted, the electric bicycle 38 establishes communication with the relevant cloud memory 39 in order to download the particular user settings. The wireless communication taking place in this case comprises, according to FIG. 3B, uploading the corresponding user identification that retrieves the user settings (arrow 40), looks up the user identification (Lookup, arrow 41), and downloads the relevant user settings (arrow 42).

[0035] In alternative embodiments, the database can be updated regularly, wherein the newest available data are used in each case. As a result, problems can be avoided in situations in which a connection cannot be established.

[0036] While the embodiment described above with reference to FIGS. 2A-B is suitable, in particular, for parents who would like to ensure that their children use the electric bicycle with the scope of safety functions that are suitable for the particular situation, the second implementation described with reference to FIGS. 3A-B is suitable, in particular, for bicycle rental businesses that have a large number of electric bicycles and for which it is not practical to individually program every single electric bicycle. In the latter case, the bicycle rental business can also provide, for example, personalized rental offers (e.g. granting the option to make full use of the entire 25-km/h power output of the electric bicycle for an additional fee).

[0037] In further embodiments, the utilization of the electric bicycle can also be recorded in a report file or an appropriate memory card. Based thereon, for example, the regular use of the safety helmet can be discussed between parents and children, or an insurance company can monitor the compliance with certain contractual conditions.

[0038] According to one further aspect of the disclosure, one or more measures can be taken for the case in which a proper key is not utilized. In this case, for example, an assistance by the electric motor can be deactivated while, simultaneously, all safety systems are switched on. In one alternative embodiment, the electric motor can also counteract the pedal operation, whereby the electric bicycle is shut off or is rendered immobile.

[0039] In this case, the disclosure also contains embodiments, in particular, in which the electric bicycle also remains usable, in principle, even in the absence of a proper key, wherein, in this case, e.g. only a failsafe mode without electric motor assistance is permitted. According to the disclosure, in particular, the above-described, personalized requirement of individual safety functions (see table 1) can be combined with an immobilization of the electric bicycle or a limitation to a failsafe operating mode without electric motor assistance in the absence of a proper key.

[0040] While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the disclosure. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the disclosure.
