Abstract

SISTEMA DE CONTROLE PARA UM MóDULO DE CONTROLE DE UM VEìCULO, E, METODO DE OPERAR UM MóDULO DE CONTROLE DE UM VEìCULO. Um sistema de controle para um módulo de controle de um veículo inclui um primeiro núcleo de circuito integrado (JC) de um processador primário que gera um primeiro sinal de controle usando uma unidade de processamento central (CPU). Um segundo núcleo de circuito integrado IC do processador primário gera um segundo sinal de controle usando uma segunda CPU e gera um sinal de controle remediador baseado na primeiro sinal de controle e no segundo sinal de controle.
