Abstract

PROCESSO PARA A DETECçãO DA VELOCIDADE DE RODAGEM DE UM VEìCULO AUTOMOTOR E DISPOSITIVO PARA A EXECUçãO DO PROCESSO. A presente invenção detecção de uma velocidade de rodagem de um veículo automotor, é detectada uma seqüência de pulsos em função da velocidade de rodagem e é cantada a quantidade dos pulsos dentro de um intervalo previsto. A partir da quantidade dos pulsos dentro do intervalo calcula-se a velocidade. Uma memória (9), na qual é armazenada a quantidade dos pulsos, é apagada ao final do intervalo. O processo para o cálculo da velocidade de rodagem apresenta um esforço de cálculo particularmente pequeno.
