Method and warning device for warning a driver of a vehicle and vehicle
First Claim
1. A method for warning a driver of a vehicle, comprising:
- determining a position of the vehicle on a roadway;
obtaining data relating to the course of a curved roadway in an area ahead of the vehicle with regard to the determined position;
obtaining data relating to a self-motion of the vehicle using a driving dynamics sensor;
dividing the curved roadway in the area ahead of the vehicle into at least two zones of criticality for each curve as a function of the data relating to the course of the curved roadway and the data relating to the self-motion;
assigning an assessment to each of the zones of criticality commensurate with a driving behavior of the vehicle in the zones of criticality;
modifying the assessment in response to information received from another vehicle positioned in a region of the curved roadway relating to a characteristic of the curved roadway using car-to-car-communication of a car-to-car-communication system; and
outputting the assessment of each zone of criticality to the driver of the vehicle.

Abstract
In a method for warning a driver of a vehicle, the position of the vehicle on the roadway is determined. For the determined position of the vehicle, data relating to a curved roadway course in the area ahead of the vehicle are obtained and data relating to a self-motion of the vehicle are obtained using a driving dynamics sensor. The curved roadway in the area ahead of the vehicle is divided into at least two zones of criticality as a function of the data relating to the curved roadway course and the data relating to the self-motion, wherein each zone of criticality is assigned an assessment which assesses the driving behavior of the vehicle within the respective zone of criticality, and the assessments are outputted to the vehicle driver.

9. A warning device for warning a driver of a vehicle, comprising:
-
a position determining unit for determining a position of the vehicle on a roadway; a data acquisition unit operably coupled to the position determining unit and configured to obtain data relating to the course of a curved roadway in an area ahead of the vehicle with regard to the determined position; a driving dynamics sensor configured to obtain data relating to a self-motion of the vehicle; an assessment unit configured to divide the curved roadway in the area ahead of the vehicle into at least two zones of criticality for each curve as a function of the data relating to the course of the curved roadway and the data relating to the self-motion, wherein an assessment which assesses a driving behavior of the vehicle within each of the zones of criticality is assignable to each of the zones of criticality; a car-to-car-communication system configured to modify the assessment in response to information relating to a characteristic of the curved roadway and received from another vehicle positioned in a region of the curved roadway via a car-to-car-communication; and an output unit for outputting the assessment to the vehicle driver.
