Abstract

"PROCESSO E DISPOSITIVO DE DETECçãO DE UMA CONDIçãO DE RODAGEM SEM PRESSãO DE UM PNEUMáTICO DE UM VEìCULO, ELEMENTO DE INSERçãO DE SEGURANçA, PNEUMáTICO, E, RODA". Processo de detecção de uma condição de rodagem sem pressão de um pneumático de um veículo, o dito pneumático estando montado em uma roda, tal que: capta-se uma grandeza f(<244>, t) que varia com o deslocamento angular da roda no tempo; elabora-se sinais de medida que variam com a velocidade angular da roda d<244>(t)/dt; calcula-se uma grandeza característica da dispersão dos sinais de medida; dispara-se um alarme quando a grandeza característica satisfaz uma relação dada.
