Abstract

"MéTODO PARA DETECçãO DE BAIXAS TAXAS DE VAZAMENTO EM UM PNEUMáTICO". Metodologias de taxas de vazamento múltiplas são combinadas e operam em paralelo em um sistema, para proporcionar resultados ótimos sob diferentes condições dos pneumáticos. As metodologias podem operar contínua ou alternativamente. Algoritmos e metodologias de grande taxa de vazamento e de baixa taxa de vazamento em série podem ser, por exemplo, dispostas em um sistema, no qual, para grandes taxas de vazamento, uma metodologia de grande taxa de vazamento é empregada e usada para disparar um aviso. Em algum valor limite de baixa taxa de vazamento pré-designado, o sistema emprega uma metodologia de baixa taxa de vazamento, ou como um monitor diagnóstico exclusivo ou em paralelo com uma metodologia de grande taxa de vazamento auxiliar. No sistema analítico de baixa taxa de vazamento, uma variação na pressão do pneumático é correlacionada com uma variação na energia dentro de um sistema de veículo, de acordo com o algorítmo W = <sym> <30>P * dx, e algoritmos derivados são usados para calcular um tempo final e uma queda de pressão no tempo final, como uma base para emitir um aviso de baixa pressão.
