Abstract
"SISTEMA DE FREIO DE VEìCULO". A invenção se refere a um sistema de freio de veículo de um veículo automotor, com um servofreio controlável eletronicamente, com uma câmara de vácuo e uma cama de pressão, as quais são separadas uma da outra por uma parede móvel, com uma disposição de válvula de controle, a qual pode ser ativada por meio de um equipamento de ativação eletromagnético, e através da qual é ajustável uma diferença de pressão entre a câmara de pressão e a câmara de vácuo, sendo que a parede móvel varia sua posição na dependência das relações de pressão na câmara de vácuo e na câmara de pressão e, neste caso, ativa um cilindro de freio principal, sendo que o equipamento de ativação eletromagnético, na operação, é carregado por uma unidade de controle eletrónica com sinais de corrente, os quais são gerados na unidade de controle eletrónica na dependência de estados dinâmicos de marcha ou de influências externas, caracterizado pelo fato de que na existência de determinados estados dinâmicos de marcha ou de influencias externas ou de combinações dos mesmos, que tornam necessária a ativação do cilindro de freio principal dentro de um intervalo de tempo predeterminado com uma probabilidade predeterminada, a unidade de controle eletrónica gera sinais de corrente para o equipamento de ativação eletromagnético, de modo que a disposição de válvula de controle é ativada em uma tal medida, que ao menos folga existente, trajetos em vazio ou trajetos mortos condicionados por tolerâncias, são superados ao menos em uma parte do sistema de freio de veículo.
