Abstract
A method for classifying an accident event of a two-wheeled vehicle, in particular a bicycle. The method can be run in the form of an algorithm in a device comprising an analysis unit in order to indicate to the rider or a third party that the two-wheeled vehicle has been involved in a collision or has fallen over using a corresponding generated and/or transmitted item of information. The device can be used in a two-wheeled vehicle, such as a bicycle or in particular in an electric bicycle. However, it can of course also be used in a motorcycle or another single-track vehicle.
Claims12
A method for classifying an accident event of a two-wheeled vehicle, comprising the following steps:
- detecting first and second sensor variables, which represent acceleration of the two-wheeled vehicle in two directions in a movement plane of the two-wheeled vehicle;
- generating a first integration variable based on a temporal integration of the first sensor variable;
- generating a second integration variable based on a temporal integration of the second sensor variable;
- performing a classification of the accident event based on the first and the second integration variables, and
- detecting a roll angle which represents a rotation of the two-wheeled vehicle about a longitudinal axis of the two-wheeled vehicle;
- and
- detecting a pitch angle which represents a rotation of the two-wheeled vehicle about a transverse axis of the two-wheeled vehicle,
- wherein the performing of the classification of the accident event additionally includes performing the classification based on the roll angle and pitch angle,
- generating an energy variable based on the first and the second integration variable;
- generating a tilt variable based on the roll angle and the pitch angle, wherein the performing of the classification of the accident event includes performing the classification based on the energy variable and tilt variable;
- and
- (i) generating an item of information that represents a collision of the two-wheeled vehicle when the energy variable exceeds an energy threshold value first and then the tilt variable exceeds a tilt threshold value, or (ii) generating an item of information that represents the two-wheeled vehicle having fallen over sideways when the energy variable does not exceed the energy threshold value and the tilt variable does not exceed the tilt threshold value.
