Abstract
A method for determining parameters for the viscosity or temperature of a brake fluid of a vehicle by way of a predetermined pressure build-up within time limits in at least one defined section of a brake circuit and for detecting a pressure in the said section and/or a time which is required for the build-up of the said pressure.
Claims13
A circuit arrangement for a brake system for a motor vehicle having a first axle and a second axle, and wheels on said axles, at least one circuit which conditions and evaluates sensor signals, determines speed, deceleration, and/or acceleration of an individual one of said wheels and compares resulting values one to the other and to predetermined threshold values, characterized in that the circuit arrangement can activate an emergency function where said wheels are braked to the extent that at least one wheel of the first axle and one wheel of the second axle exhibit a minimum speed and further wherein the circuit arrangement determines the faster wheel one of said wheels for each of the axles, subsequently selects the slower wheel of the faster wheels of the two axles and controls the speed of the slower wheel so that this speed generally corresponds to a preadjusted nominal speed.
