Abstract

método e sistema para reduzir ou eliminar ruído gerado pelos freios de disco de um veículo motor. um sistema de freio de veículo motor compreende um controlador eletrônico (e2) configurado para receber sinais de emissão dos sensores (s) associados aos freios de disco de veículo motor, o que permite a detecção de um parâmetro (n) indicativo de ruído gerado de cada freio de disco. quando a geração de ruído é detectada, o controlador eletrônico (e2) ativa uma função de atenuação de ruído de um primeiro tipo se o veículo está freando e de um segundo tipo se o veículo não está freando. a função de atenuação de ruído do primeiro tipo envolve reduzir a pressão de ativação do atuador de fluido associado ao freio de disco para o qual a geração de ruído é detectada a função de atenuação de ruído do segundo tipo envolve ativar temporariamente - enquanto o veículo motor está em movimento e não está freando - o atuador de fluido associado ao freio de disco que está gerando ruído. o controlador eletrônico (e2) é também configurado para receber uma pluralidade de sinais indicativos de um ou mais parâmetros de operação do veículo motor, tal como ângulo da direção, velocidade do veículo, velocidade de rotação de cada roda, ângulo de guinada do veículo, engrenagem inserida, posição da embreagem, e modos de direção, o que permite que condições sejam definidas, em que é preciso ser dada prioridade à segurança do veículo motor, e em que a função de atenuação de ruído precisa ser excluída.
