A method for monitoring the travel speed of a bicycle, in particular a pedelec. The method includes: providing a power supply for a speed signal transmitter, ascertaining a first speed for the bicycle, interrupting the power supply for the speed signal transmitter for a specifiable interruption time span, while the power supply is switched off, ascertaining a second speed, ascertaining a comparison result by comparing the ascertained first and second speed, and recognizing a faulty speed signal transmitter as a function of the result of the comparison.

A visual warning assembly, configured to make a warning from one vehicle to another vehicle. The visual warning assembly has a case with a front face joined to a base and an antenna. A channel display button, a channel selector button, a power button, a green lighted button, a yellow lighted button and a red lighted button, arranged on the front face. A mounting ball is magnetically joined to the base. A microcontroller is electrically coupled to the green lighted button, the yellow lighted button, and the red lighted button. The microcontroller is programmed with instructions to: receive a communication from a second visual warning assembly. Then, engage one member of a lighted button set consisting of the red button, the yellow button, and the green button creating an indicating light. Finally, receiving a signal from a user making the indicating light an activated button

An early-warning system, method, and apparatus for steering of a two-wheeled vehicle, and a corresponding two-wheeled vehicle including a display apparatus. The system includes: a first control system and a second control system both operating independently and exchanging data between each other in real time; the first control system is configured to: monitor a steering state of the two-wheeled vehicle in real time and generate steering state data; generate early-warning state data based on the steering state data; transmit at least part of the steering state data and the early-warning state data to the second control system in real time; and control corresponding components of the two-wheeled vehicle to operate according to control instructions received from the second control system and internal preset instructions; and the second control system is configured to: control a display of the display apparatus based on the steering state data and/or the early-warning information.

A bicycle electronic equipment configured to be attached to a location of the bicycle includes a data processing system, a multicolour light source, and a switch. The switch includes a push-button and a two-state electric circuit. The data processing system is configured to: (a) make the light source emit cyclically repeating N coloured light emitting patterns, with N>=3, wherein coloured light emitting patterns immediately consecutive in the cyclical repetition differ in color and/or type of emitting pattern; (b) monitor the state of the switch during execution of step (a); and (c) perform a different action among N different actions according to which of the N coloured light emitting patterns the source is emitting upon the state switching of the switch.

A method of controlling a personal mobility system includes displaying a virtual object on an augmented reality wearable device, the virtual object being located in a position in the field of view of the augmented reality device corresponding to a position in the real world. Proximity of the personal mobility system or a user of the personal mobility system with the position in the real world is detected. In response to the detection of proximity, a performance characteristic of the personal mobility system is modified.

A protective warning system for a vehicle is provided. A device comprises: a long-range camera and a stereoscopic camera positioned in a housing to image external objects in a rear-facing direction when the housing is mounted to a vehicle. A controller detects, using images from the long-range camera, an external object in the rear-facing direction and process stereoscopic images from the stereoscopic camera to determine when the external object is located with a first zone or a second zone extending in the rear-facing direction, the second zone being closer to the stereoscopic camera than the first zone. In response to determining that the external object is located with the first zone or the second zone, the controller controls the one or more notification devices to provide one or more first or second notifications associated with a first or second urgency level.
