Abstract: A prediction system and a prediction method for at least one brake system component of a brake system of a vehicle by ascertaining value groups of in each case at least two different variables during at least one driver-induced and/or autonomous braking process of the vehicle, the at least two variables of the same value group are ascertained simultaneously and in a braking situation in which at least one of the variables lies outside its respective specified normal value range and/or a temporal derivative of at least one of the variables lies outside a quasi-static range respectively specified for the respective variable, and estimating, using the ascertained value groups, whether the occurrence of at least one functional impairment of at least the one brake system component of the brake system is probable at least during a specified prediction time interval.

Abstract: A prediction device for at least one brake system component of a brake system of a vehicle. The prediction device is configured to enter provided value pairs, which respectively have values ascertained during several driver-induced and/or autonomous braking processes of the vehicle and respectively comprise an ascertained input variable and a simultaneously ascertained output variable, into a coordinate system, divided into several state sectors, with the first axis indicating the input variable and the second axis indicating the output variable; to ascertain a frequency distribution of the value pairs to the various state sectors; and, after at least two ascertainments of frequency distributions for value pairs ascertained in different time intervals, to estimate whether an occurrence of at least one functional impairment on at least one brake system component of the brake system is probable during a specified prediction time interval.

Abstract: A prediction device for at least one brake system component of a brake system of a vehicle. The prediction device is configured for provided value groups which each have values and/or information ascertained during a plurality of driving dynamics regulating processes executed during driver-induced and/or autonomous braking processes of the vehicle and each include an ascertained input variable, a simultaneously ascertained output variable, and an item of friction value or position indication information relating to a roadway simultaneously traveled on by the vehicle, to enter the value groups into a coordinate system having a plurality of target sectors which each correspond to a specified target relation between the input variable and the output variable at a specific friction value, and to estimate whether an occurrence of a functional impairment of a brake system component of the brake system is probable at least during a specified prediction time interval.

Abstract: A prediction device and method for a brake system component of a brake system of a vehicle. The method includes: ascertaining value groups, which respectively have values ascertained during several braking processes of the vehicle, each comprising a braking request specification variable ascertained at a point in time, at least one brake system response variable ascertained at the same point in time, and a vehicle response variable ascertained at the same point in time; entering the ascertained value groups into coordinate systems which each has at least two axes, which respectively indicate the braking request specification variable or a braking request specification variable, the brake system response variable or at least one of the brake system response variables, and/or the vehicle response variable or a vehicle response variable; and estimating based on the coordinate systems whether an occurrence of a functional impairment of the brake system component is probable.
