Method for determining a suitable curve speed for vehicles, device for performing said method, and use thereof

1 . A method for determining a suitable curve speed for a single-track motor vehicle, the method comprising:

with reference to a current user of the vehicle, initially in a first step, for at least one particular curve, forming a ratio of a curve speed traveled by the current user on the at least one particular curve in the past to a curve speed traveled by at least one other driver on the same at least one particular curve in the past;

in a second step, for a current or upcoming curve, multiplying at least one curve speed selected by at least one other driver for the current or upcoming curve in the past, by the ratio ascertained in the first step;

in a third step, outputting a speed ascertained in the second step as a speed recommendation to the current user of the vehicle; and

operating a driver assistance system to produce haptic output to the current user based on the output speed.

2 . The method according to claim 1 , wherein, for the at least one particular curve, a plurality of curve speeds of other drivers on the at least one particular curve in the past is used and a mean value, quantile, or analysis of standard deviations of relevant curve speeds for the at least one particular curve is used as a basis for forming the ratio in the first step.

3 . The method according to claim 1 , wherein past curve speeds of other drivers and curve speeds of the current user of the vehicle for the upcoming or current curve are also included in the ratio formation according to the first method step.

4 . The method according to claim 1 , wherein roadway parameters of the upcoming or current curve are additionally considered for ascertaining a recommended curve speed, wherein the roadway parameters include at least one of: a roadway quality, a number of lanes of the roadway, a course of a curvature, a road width, an angle subtended by the curve, an overall curviness of a route, a road category, a transverse gradient, a possible slope of the road, a geographic location, and an administrative speed limits.

5 . The method according to claim 4 , wherein consideration of the roadway parameters is carried out in such a way that only roadways that are similar in terms of their roadway parameters to the current or upcoming curve to a specifiable extent are considered for calculation of the ratio according to the first method step.

6 . The method according to claim 1 , wherein an age of data that are considered in the ratio formation and that are historical data regarding the curve speed for at least one particular curve is also considered when forming the ratio according to the first method step, such that older data are less heavily weighted than newer data.

7 . The method according to claim 1 , wherein additional vehicle data of the vehicle currently being used by the current user, including: (i) an actually driven curvature, and/or (ii) slanted positions of the vehicle, and/or (iii) possible interventions by assistance systems of the vehicle and/or (iv) a driver behavior, are included for calculating a suitable curve speed for the current or upcoming curve.

8 . A driver assistance system for a single-track motor vehicle, the driver assistance system comprising:

an arrangement configured to determine a suitable curve speed for vehicles, by performing:

with reference to a current user of the vehicle, initially in a first step, for at least one particular curve, forming a ratio of a curve speed traveled by the current user on the at least one particular curve in the past to a curve speed traveled by at least one other driver on the same at least one particular curve in the past;

in a second step, for a current or upcoming curve, multiplying at least one curve speed selected by at least one other driver for the current or upcoming curve in the past, by the ratio ascertained in the first step;

in a third step, outputting a speed ascertained in the second step as a speed recommendation to the current user of the vehicle using the driver assistance system; and

operating the driver assistance system to produce haptic output to the current user based on the output speed.

9 . A single-track motor vehicle, comprising:

a driver assistance system for the single-track motor vehicle, the driver assistance system including:

an arrangement configured to determine a suitable curve speed for vehicles, by performing:

with reference to a current user of the vehicle, initially in a first step, for at least one particular curve, forming a ratio of a curve speed traveled by the current user on the at least one particular curve in the past to a curve speed traveled by at least one other driver on the same at least one particular curve in the past;

in a second step, for a current or upcoming curve, multiplying at least one curve speed selected by at least one other driver for the current or upcoming curve in the past, by the ratio ascertained in the first step;

in a third step, outputting a speed ascertained in the second step as a speed recommendation to the current user of the vehicle using the driver assistance system; and

operating the driver assistance system to produce haptic output to the current user based on the output speed.
