Abstract

"PROCESSO E DISPOSITIVO PARA A DETECçãO DE PRESSãO RESIDUAL EM UM SISTEMA DE FREIO, ESPECIALMENTE EM UM CILINDRO DO FREIO". De acordo com a invenção, a suspeita de uma pressão residual em um sistema de freio é constatada por meio de monitoração "grossa contínua", da pressão no sistema mencionado. Se uma tal suspeita da pressão residual for constatada, então realiza-se eventualmente várias vezes um processo de monitoração fina, sendo que um órgão de descarga de pressão do sistema de freio é aberto e é detectado por um sensor, se a pressão atual está caindo, e em caso afirmativo com que intensidade.
