Abstract

"DISPOSITIVO DE CONTROLE PARA FREIO DE ESTACIONAMENTO DE VEìCULO MOTORIZADO". Um dispositivo de controle para o freio de estacionamento de um veículo motorizado tem um cilindro hidráulico com uma câmara do pistão que pode ser pressurizada por meio de um arranjo de válvula, e tem um pistão hidráulico conectado mecanicamente a elementos de engatamento do freio de estacionamento. O freio de estacionamento é forçado para uma posição engatada ou desengatada, dependendo da pressão hidráulica na câmara do pistão. A câmara do pistão se conecta a um sensor de pressão que fornece sinais de pressão que representam o estado do freio de estacionamento e que são avaliados por uma unidade de controle elétrica. A unidade de controle define um primeiro limiar de pressão predeterminado que corresponde ao estado engatado do freio de estacionamento, e um segundo limiar de pressão predeterminado que corresponde ao estado desengatado do freio de estacionamento.
