Abstract

In a method for determining the temperature of a wheel-braking device of a brake system, the current disc temperature of the brake disc is determined based on the last-determined disc temperature, the energy supplied to the brake disc since the last temperature determination, and the energy discharged by the brake disc since the last temperature determination. The current caliper temperature of the brake caliper of the wheel-braking device is determined by means of the current disc temperature of the brake disc.

Claims14

Dependent claims

A method for determining the temperature of a wheel-braking device that includes a brake disc and a brake caliper, said method comprising:

determining current disc temperature (Tdisc, current) of the brake disc as a function of a last-determined disc temperature (Tdisc, old), energy (Efriction, disc) supplied to the brake disc since determination of the last determined disc temperature, and energy (Edisc, dis) discharged by the brake disc since determination of said last-determined disc temperature;
and
determining current caliper temperature (Tcaliper, current) of the brake caliper of the wheel-braking device as a function of the current disc temperature (Tdisc, current) of the brake disc.

Dependencies are inferred from the claim text.
