Abstract

UN MOTOR DE SERVODIRECCION DE VEHICULO (31) PROPORCIONA UNA FUERZA PARA HACER GIRAR LAS RUEDAS DE DIRECCION DE UN VEHICULO (14 Y 16). UNA VALVULA DE CONTROL DE SERVODIRECCION (22) INCLUYE UNA PRIMERA Y SEGUNDA PARTE DE VALVULA RELATIVAMENTE GIRATORIAS (40 Y 42). LAS PARTES DE LAS VALVULAS PRIMERA Y SEGUNDA (40 Y 42) LLEVAN LIQUIDO PARA HACER FUNCIONAR EL MOTOR DE SERVODIRECCION DEL VEHICULO (31) EN MOVIMIENTO RELATIVO. UN DISPOSITIVO (114) DETECTA AL MENOS UNA CARACTERISTICA DE OPERACION DEL VEHICULO Y PROPORCIONA UNA SEÑAL INDICATIVA DE AL MENOS UNA CARACTERISTICA DE OPERACION DEL VEHICULO. EN UNA REALIZACION PREFERIDA, ESA CARACTERISTICA DE OPERACION DEL VEHICULO ES LA ACELERACION LATERAL. UN DISPOSITIVO DE TRANSMISION DE FUERZA (116, 120, Y 130) RESISTE EL MOVIMIENTO RELATIVO ENTRE LA PRIMERA Y SEGUNDA PARTE DE LA VALVULA (40 Y 42) CON UNA FUERZA QUE VARIA COMO UNA FUNCION DE LA SEÑAL DE SALIDA. LA FUERZA VARIA COMO UNA FUNCION DE LA ACELERACION LATERAL DEL VEHICULO.
