Laboratorní stav pro ověřování funkce ABS jednotky

Abstract

My thesis is focused on designing laboratory stand for testing ABS units. The ABS unit is composed of a uniprocessor board, sensors from Hall probes and magnetic wheels. Interventions are controlled by the RC servomechanisms. Idea of the model is in stopping a mass created by a flywheel, which represents roadway by wheel braked with mechanical disc brake in minimal skid way. After model accelerates, used algorithm starts breaking with mechanical brake and simultaneously read operating speed of the flywheel. According to the measured data, algorithm identifies skid and thus creates intervention on the brake. Measured values can be visualized by the application created for export of the measured values. Thesis serves for designing algorithms able to work with sensor signals and afterwards solve brakes interventions.
