Abstract
LAS MEDIDAS DE LA VELOCIDAD DE UNA RUEDA SE COMPARAN PARA DETECTAR EL GIRO EXCESIVO DE LA RUEDA. UNA SALIDA DEL DETECTOR DE GIRO DE LA RUEDA (3-10) ES COMUNICADA A UN MEDIO REDUCTOR DEL IMPULSO (20) PARA REDUCIR EL IMPULSO DEL VEHICULO EN RESPUESTA A LA DETECCION DEL GIRO EXCESIVO DE LA RUEDA. EL IMPULSO REDUCIDO DEL VEHICULO SE COMPARA MEDIANTE UN VALOR PREDETERMINADO MEDIANTE UN SUSTRACTOR (24). UNA ESTIMACION DE LA FRICCION SUPERFICIAL SE ACTUALIZA CON UN VALOR QUE DEPENDE DE LA SALIDA DE SUSTRACTOR (24).
