Abstract

DISPOSITIVO DE MANDO, DE SEGURIDAD Y DE DIAGNOSTICO PARA UN CIRCUITO ELECTRICO DE UN VEHICULO. COMPRENDE UN CIRCUITO DE VIGILANCIA FORMADO POR UNA FUENTE DE CORRIENTE CONTINUA, POR UN TRANSISTOR DE POTENCIA DEL TIPO MOS, MONTADO EN SERIE ENTRE LA FUENTE DE CORRIENTE Y AL MENOS UNO DE LOS APARATOS ELECTRICOS DE UTILIZACION, Y POR UN MICROPROCESADOR PROGRAMADO PARA VERIFICAR PERIODICAMENTE LA RELACION LOGICA V<G<S ~Y O Y V<D<S~U1/2 V<B<A<T, EN LA QUE V<D<S ES LA CAIDA DE TENSION EN EL TRANSISTOR MOS, V<B<A<T ES LA TENSION NOMINAL EN LOS BORNES DE LA FUENTE DE CORRIENTE. EL HECHO DE QUE NO SE SATISFAGA LA MENCIONADA RELACION LOGICA SE CONSIDERA COMO SEÑAL INDICATIVA DE AUSENCIA DE CORTOCIRCUITO EN LA INSTALACION.
