Method for determining the speed of a vehicle and vehicle
First Claim
1. A method for determining a speed of a vehicle, comprising:
- ascertaining a first distance travelled by the vehicle within a time interval on the basis of data ascertained by at least one first revolution sensor of a first tire of the vehicle and a second revolution sensor of a second tire of the vehicle;
ascertaining a second distance travelled by the vehicle within the time interval on the basis of data ascertained by a position-determining device;
determining, by a vehicle computer, that a deviation between the ascertained first distance and the ascertained second distance exceeds a predetermined threshold value; and
in response to the determining,classifying, by the vehicle computer, a speed of the vehicle on the basis of the ascertained second distance as the intrinsic speed of the vehicle,providing a determined speed of the vehicle to at least one driver-assistance-system of the vehicle, andadjusting an operating mode of at least one driver assistance system as a function of the deviation between the ascertained first distance and the ascertained second distance.

Abstract
A subject matter of the application relates to a method for determining a speed of a vehicle. In one embodiment, the method includes ascertaining a first value of a distance traveled by the vehicle within a time interval on the basis of data ascertained by at least one first revolution sensor of a first tire of the vehicle and a second revolution sensor of a second tire of the vehicle; ascertaining a second value of a distance traveled by the vehicle within a time interval on the basis of data ascertained by a position-determining device; and comparing the ascertained first value and the ascertained second value. If a deviation between the ascertained first value and the ascertained second value exceeds a predetermined threshold value, the method includes classifying a speed determined on the basis of the ascertained second value.

10. A vehicle, comprising:
-
a first revolution sensor for a first tire and a second revolution sensor for a second tire of the vehicle a first ascertainment device that ascertains a first distance travelled by the vehicle within a time interval on the basis of data ascertained by at least one of the first revolution sensor and the second revolution sensor; a second ascertainment device that ascertains a second distance travelled by the vehicle within a time interval on the basis of data ascertained by a position-determining device; a classification device that classifies a speed determined on the basis of the ascertained second distance as the intrinsic speed of the vehicle and provides a determined speed of the vehicle to at least one driver assistance system of the vehicle, when a deviation between the ascertained first distance and the ascertained second distance exceeds a predetermined threshold value; and wherein the driver assistance system adjusts an operating mode of at least one driver assistance system as a function of the deviation between the ascertained first distance and the ascertained second distance. - View Dependent Claims (11, 12)
