Abstract

conjunto de pneu, e, sistema de veículo. a presente invenção se refere a um conjunto de pneu (t, t) que inclui um pneu (tr) e um sensor de área de contato e de altura do pneu (100, 100?) disposto, ao menos parcialmente, dentro de uma câmara de pneu (c) do pneu (tr). o sensor (100, 100) inclui uma fonte de radar (160) operável para direcionar ondas de radar de comprimento de onda da ordem de milímetros na faixa de 120 a 240 giga hertz (ghz) a uma superfície interna (isf) do pneu (tr). o sensor (100, 100') inclui também um receptor de radar (170) operável para gerar um sinal mediante o recebimento das ondas de radar refletidas. um processador (106, 106?, 136, 136, 112, 112') é operável para determinar uma distância entre a fonte de radar (160) e um alvo (tg) com base em pelo menos um dentre: (i) um tempo de voo; (ii) um deslocamento de fase de frequência. o sensor (100, 100') inclui uma antena (104, 104') para transmitir dados a um sistema externo à câmara de pneu (c). o processador (106, 106?, 136, 136, 112, 112') determina opcionalmente as dimensões área de contato do pneu (cp, cp') e/ou pode gerar uma imagem da área de contato do pneu (cp, cp') para correlacionamento de padrões de imagem a fim de determinar o estado de insuflação e/ou de carga do pneu (tr).
