PROCEDE ET AGENCEMENT DE CIRCUIT POUR LA RECONNAISSANCE DE VITESSE DANS UNE BOITE DE VITESSES D'UN VEHICULE AUTOMOBILE |
摘要 |
<p>A method and a circuit configuration for gear detection in a motor vehicle transmission detect a signal corresponding to an input rpm and a signal corresponding to an output rpm of the transmission. A quotient of the output rpm to the input rpm is formed. A gear that has been engaged is detected from this quotient and from a known gear ratio of the transmission. A variation over time of the ratio of the output rpm to the input rpm of the transmission is ascertained and compared with a limit value. If the limit value is exceeded, a determination is made that no gear has been engaged.</p> |
