Abstract

um controlador de um motor de combustão interna recebe uma solicitação de frenagem de motor e, em resposta à mesma, ativa um subsistema de frenagem de exaustão. além disso, após passagem de um período de tempo, o controlador adicionalmente ativa um subsistema de frenagem com liberação de compressão. o período de tempo é preferencialmente selecionado para permitir desenvolvimento de contrapressão aumentada em um sistema de exaustão do motor de combustão interna antes da ativação do subsistema de frenagem com liberação de compressão. além disso, em seguida à ativação do subsistema de frenagem de exaustão, o controlador pode, se o subsistema de frenagem de exaustão falhou e, se assim for, fazer o subsistema de frenagem com liberação de compressão para operar em um modo de potência de frenagem reduzida, por exemplo, a menos do que a potência de frenagem total potencialmente até e incluindo nenhuma potência de frenagem.
