Patent number: 11091165Abstract: A method for estimating a probability distribution of the maximum coefficient of friction (?) at a current and/or future waypoint (s, s*) of a vehicle. According to the method, a first probability distribution (WV1) for the maximum coefficient of friction (?) at the waypoint (s) of the vehicle is determined by a Bayesian network from a first data set, which is, or was determined, for one, in particular current, waypoint (s) of the vehicle and which characterizes the maximum coefficient of friction (?) at the waypoint (s) of the vehicle.Type: GrantFiled: May 11, 2017Date of Patent: August 17, 2021Assignees: ZF FRIEDRICHSHAFEN AG, LUCAS AUTOMOTIVE GMBHInventors: Matthias Schlegel, Jochen Abhau, Heinz-Joachim Gilsdorf, Julian King, Jochen Köhler, Horst Krimmel, Gerhard Niederbrucker, Lara Ruth Turner, Volker Wagner, Robert Zdych, Vanessa Adler, Sascha Heinrichs-Bartscher, Ralf Raffauf, Holger Simon, Walter Stein
