  • the names of states, cities, roads and so-called points of interest (POI) can be entered.
  • the command components consist of letters and are formed by PinYin syllables.
  • Character in letters based on the Latin alphabet is sound-based. Since the Chinese characters always describe exactly one syllable, the PinYin phonetic transcription is also syllable-based.
  • the Chinese syllables always consist of an initial and a final, the initial sound can be advantageously used as an initial letter for input by the method according to the invention. It is also advantageous that personal pronunciation errors are suppressed, since it only depends on the first letter of a PinYin syllable.
  • command components of an operating command are stored separately in the database by separators, in particular by blanks. Also from this point of view, the application of the method according to the invention in PinYin syllables is particularly favorable, since in this case the syllables are already separated by spaces. Alternatively, the command components of an operating command may also be stored separated by capital letters in the database.

Abstract

L'invention concerne un procédé de saisie d'instructions de commande dans un système automatisé, notamment de saisie de cibles de navigation dans un système de navigation. Ledit procédé comporte les étapes suivantes: des instructions de commande (3) possibles pour la commande du système sont enregistrées préalablement dans une base de données de telle manière qu'elles sont respectivement composées d'une seule partie d'instruction (2) ou de plusieurs parties d'instructions (2), chaque partie d'instruction étant composée d'au moins deux caractères formés par des lettres et/ou des chiffres; lors de l'utilisation du système, des caractères (1) saisis dans des éléments de saisie du système en tant que lettres et/ou chiffres sont enregistrés par un utilisateur; les instructions de commande (3) dont le premier caractère d'une instruction de commande (3) composée d'une seule partie d'instruction (2), correspond à un seul caractère saisi, ou dont les premiers caractères des instructions de commande consécutives (2) correspondent à une suite de caractères saisis (1), sont déterminées dans la base de données; les instructions de commande (3) déterminées sont émises dans une unité d'émission du système pour la sélection et/ou la confirmation par l'utilisateur; et une instruction de commande confirmée (3) est exécutée ou traitée ultérieurement par le système. L'invention concerne également un système de navigation ou un système d'assistance au conducteur permettant de mettre en oeuvre ledit procédé.
