Abstract

"SISTEMA E MéTODO PARA DETECTAR CONDIçõES DE ALTERNADOR". São fornecidos um sistema e método para detectar a condição do alternador. A informação é tirada da linha de energia do veículo e dos enlaces de comunicação, e processada pelo ECU do veículo, como o ECU do sistema de frenagem antitrava do veículo, para obter dados. A amplitude de ondulação de voltagem da bateria é então calculada e comparada a velocidades de motor diferentes. Se a diferença na amplitude de ondulação nas diferentes velocidades de motor for maior que um valor limite predeterminado, um sinal é enviado para indicar que o alternador falhou.
