Title: METHOD FOR DETERMINING A SAFE SPEED AT A FUTURE WAY POINT
Abstract:
The invention describes a method for determining a safe speed (v*) at a future way point (s*) of a vehicle which is moving along a route. In this step, at least one piece of route information (in particular curve bend κ) characterizing the course of the route is determined. In addition, a first probability distribution (Pges) of a friction coefficient (μ) at the current way point (s) and/or at the future way point (s*) of the vehicle is provided. A second probability distribution (Pv) of a vehicle speed (v) at the future way point (s*) is then determined from the at least one piece of route information (κ) and the first probability distribution (Pges). The safe speed (v*) is determined from the second probability distribution (Pv) by statistical analysis.
