Abstract

resumo patente de invenção: "dispositivo de estimativa de altura do veículo e método de estimativa de altura do veículo". a presente invenção refere-se a altura de um veículo que pode ser estimada de modo barato por: detecção da velocidade da roda, que é uma velocidade de cada roda (etapa st11); que realiza análise de frequência da velocidade detectada da roda de um par de rodas esquerda e direita e cálculo das respectivas características da velocidade da roda das rodas esquerda e direita em uma frequência específica por ganho (etapa st12); cálculo de uma diferença de ganho da velocidade da roda da esquerda para direita com base nas características da velocidade da roda calculadas das rodas esquerda e direita (etapa st13); e estimativa da altura do veículo com base em uma relação correspondente entre altura da roda, da roda com relação a um corpo do veículo e um valor (velocidade da roda/ganho de entrada da superfície da rodovia) que tem como base velocidade da roda e uma entrada da superfície da rodovia que é inserida a partir da superfície da rodovia às rodas, e com base na diferença de ganho da velocidade da roda da esquerda para a direita (etapa st14). 21983246v1 1/1 21983246v1
