Abstract

[objetivo] fornecer um dispositivo de controle de pressão de fluido de freio para um veículo que possa melhorar a capacidade de resposta do freio quando um freio é reoperado por um motorista durante o controle de abs, reduzindo assim a sensação de erro e estranheza do motorista. [solução] é fornecido um dispositivo de controle da pressão de fluido do freio para um veículo que inclui um dispositivo de obtenção de velocidade da roda para obter a velocidade da roda e um meio de cálculo da desaceleração da carroceria do veículo para calcular uma desaceleração da carroceria do veículo com base na velocidade da roda. se uma condição é satisfeita em que a desaceleração da carroceria do veículo continua a permanecer em uma taxa baixa de menor ou igual a um valor de limiar predeterminado por um período de tempo predeterminado, a taxa de aumento de pressão no controle de aumento de pressão é alterada para um valor maior que antes que a condição seja satisfeita. [efeito] a pressão de fluido de freio de uma pinça de freio (pressão de cal) pode ser rapidamente aproximada da pressão de fluido de um cilindro mestre (pressão m/c). portanto, é possível melhorar a resposta do freio quando o freio é reoperado pelo motorista durante o controle de abs, reduzindo assim a sensação de erro e estranheza do motorista.
