Abstract

SISTEMA A BASE DE PIEZOELÉCTRICO E MÉTODO PARA DETERMINAÇÃO DE CARGA DE PNEU. Sistemas e métodos de determinação de carga de pneu dos parâmetros de pneu medidos incluem utilização de um sensor a base de piezoelétrico para obter um ou mais parâmetros de trecho de contato (por exemplo, tempo de entrada de trecho de contato, tempo de saída de contato, tempo de trecho de contato total e ângulo de trecho de contato) e um ou mais sensores adicionais para obter pressão de pneu. Medições de parâmetro de trecho de contato selecionados e valores de pressão são então comparados com combinações conhecidas de valores de parâmetro de trecho de contato e valores de pressão armazenados em uma tabela de consulta. Um valor de carga de pneu determinado correspondente é então provido com saída eletrônica.
