Abstract

"PROCESSO E DISPOSITIVO PARA DETERMINAçãO DA PRESSãO DE RESPOSTA DE FREIOS DE VEìCULOS". Processo para determinação da pressão de resposta de freios de veículo (32-39), em que os freios (32, 33; 36-39) a serem examinados são ativados com uma pressão de teste, sendo que antes e depois da pressão de teste (P) é produzido um sinal indicador de pressão de teste (X1 ou X2) que é uma combinação linear de um sinal de aceleração e de um sinal de velocidade diferencial (S). Coincidindo os dois sinais indicadores de pressão de teste, o que é considerado como "não resposta do freio", então a pressão de teste é aumentada e produzido um novo sinal indicador de pressão de teste (X2). Não coincidindo os dois sinais indicadores de pressão de teste (Xl, X2), então a pressão de freio (P) presente é considerada como pressão de resposta.
