Embodiment Construction

[0033] figure 1 A flow chart of a method according to an embodiment of the present invention is schematically shown. figure 2 A device 1 according to an embodiment of the invention is shown. It is provided here that the device 1 can be mounted on a vehicle in order to ascertain the driving behavior of the driver of the vehicle according to the method.

[0034]The device 1 includes an acceleration sensor 2 , an output device 3 and a control device 4 . The control device 4 is connected to the acceleration sensor 2 and to the output device 3 for signal transmission. Furthermore, the control device 4 is preferably designed to implement the figure 1 method shown in .

[0035] The method includes the following steps: first, detect 100 three-dimensional signals of the acceleration sensor 1 . For this purpose, the acceleration sensor 1 can detect accelerations in three separate spatial directions x, y and z. Thus, the 3D signal shows acceleration values ​​in each spatial direct...

Abstract

The present invention relates to a method for determining a driving behaviour of a driver of a vehicle, comprising the steps: acquiring (100) a three-dimensional signal of an acceleration sensor, wherein the three-dimensional signal comprises an acceleration value in, in each case, one independent spatial direction, calculating (200) a characteristic variable of the three-dimensional signal, and outputting (300) the driving behaviour on the basis of the characteristic variable by means of an output device, wherein the characteristic variable is a measure of the aggressiveness of a driving behaviour, and wherein the characteristic variable comprises either a fractal dimension of an embedding of the three-dimensional signal and / or a Kolmogorow entropy of the three-dimensional signal.

Description

Background technique [0001] The invention relates to a method and a device for ascertaining the driving behavior of a driver of a vehicle. [0002] It can be seen from the prior art that efforts are made to obtain the driving behavior of the driver of the vehicle on public roads. Driving behavior can be especially aggression through driving maneuvers Indicated by the amount and degree of consideration of other vehicles and / or speeding. For this purpose, the signals of the acceleration sensors are evaluated. Aggressiveness is to be understood in particular as a rapid and / or sudden change in the speed and / or direction of travel of the vehicle. [0003] Deriving the driving behavior of individual drivers is of particular interest to insurance companies. In this way, insurance rates can be extended to include personal characteristics such that, for example, aggressive drivers must pay higher insurance premiums than conservative drivers. [0004] For example, US 2014 / 0191858 ...
