  • the present invention relates to a localization system for localizing small electric vehicles and a method for carrying out such localization.
  • Small electric vehicles are vehicles with an electric drive that are emission-free. As a rule, they are light in weight and small in size. They are often foldable and portable. For this reason, they are easy to take with you and are particularly suitable for covering shorter distances in the city.
  • Typical examples of small electric vehicles are electric scooters (so-called e-scooters), Segways, hoverboards, airwheels, e-skateboards, e-bikes, including e-cargo bikes and moving delivery drones.

  • the blind cane means that lying electric scooters in particular are detected too late, so that a blind or visually impaired person falls over the scooter and may injure themselves.
  • a blind cane that is held at an angle when swinging above the ground slides under the support bar of the handlebars and so the haptic feedback from the cane only comes shortly before the obstacle is reached.
  • electric scooters are also placed on stairs to subways or other transport facilities and thus become dangerous tripping hazards.
  • a system is known in the prior art in which an electric scooter is made to ring by a smartphone with a special app when a button is pressed on the smartphone while the app is open.
