Abstract

A method is provided for increasing the operational safety of at least one thermally stressed functional part of at least one vehicle brake, in particular of a commercial vehicle and/or a trailer, and/or for reducing brake wear and/or drive power, wherein the method has the following steps: inputting a temperature signal of the at least one brake, which temperature signal represents at least one temperature of the brake and/or of a functional part of the brake detected by at least one sensor, and inputting a brake request signal and/or brake pressure signal for the at least one brake; determining a thermal error condition by using the temperature signal and the brake requirement signal and/or brake pressure signal; and providing an adapted brake requirement signal and/or adapted brake pressure signal using the determined thermal error condition in order to increase the operational safety of the at least one functional part of the at least one vehicle brake exposed to thermal stress, and/or to reduce the brake wear and/or the drive power.
