Abstract

resumo patente de invenção: "dispositivo de freio de estacionamento". a presente invenção refere-se a uma válvula de freio de estacionamento (1) biestável, pelo menos um dispositivo de válvula solenoide (25) elétrico acionado a partir de uma unidade de controle (52) eletrônica,, uma válvula de relé (31) e um freio de mola (51) acionado a partir da válvula de relé (31) armazena na unidade de controle (52) eletrônica um primeiro campo característico multidimensional salvo, que na modificação de um valor desejado de pressão desejada (psoll) para o freio de mola (51), controla o dispositivo de válvula solenoide elétrico (25) com um pulso inicial (pi) com duração predeterminada (ti). essa duração de tempo é removida do campo característico armazenado. o campo característico contém valores para a duração de tempo (ti), na dependência da pressão desejada (psoll) > pressão de abastecimento (pvorr) e uma pressão diferencial (p) e da pressão medida (pist) ou uma pressão diferencial (delta p), que é a diferença de uma pressão momentânea (pist) estimada e a pressão desejada (psoll). com isso, a pressão de acionamento sem um circuito de regulação de ciclo fechado para o dispositivo de freio de estacionamento é obtida rapidamente. 1/1
