Abstract

método implementado por computador, e, sistema. a presente invenção refere-se a sistemas e métodos aqui divulgados para estimar pelo menos uma força que atua sobre um pneu montado em veículo. uma forma de onda de aceleração (150) do pneu é detectada em uma direção radial do pneu a partir de saídas amostradas de um sensor de aceleração montado no pneu (118). a forma de onda de aceleração é integrada na direção radial do pneu para gerar uma forma de onda de velocidade (etapa 220). várias amostras durante o contato com o solo são calculadas a partir de pelo menos um primeiro e segundo picos na forma de onda de velocidade, sendo que um comprimento de contato com o solo é calculado com base pelo menos no número calculado de amostras durante o contato com o solo, uma taxa de amostragem das saídas do sensor de aceleração montado no pneu, e uma velocidade do veículo. pelo menos uma força que atua no pneu é estimada a partir de pelo menos o comprimento calculado de contato com o solo (166), e um sinal de saída é gerado correspondendo à pelo menos uma força estimada que atua no pneu.
