Abstract

Procédé de réglage de maintien d'aile latérale de siège d'automobile reposant sur une technologie de reconnaissance graphique. Le procédé spécifique comprend les étapes suivantes : pendant le processus de conduite d'un véhicule, une caméra orientée vers l'avant montée sur un véhicule envoie des informations routières à un dispositif d'opération de traitement graphique en temps réel ; après la réception des informations routières, le dispositif d'opération de traitement graphique effectue un traitement d'informations ; le dispositif d'opération de traitement graphique envoie les informations traitées à un système de maintien d'aile latérale de siège ; après la réception des informations, le système de maintien d'aile latérale de siège effectue un traitement d'état d'aile latérale de siège. Un système de réglage de siège d'automobile qui combine le dispositif d'opération de traitement graphique et le système de maintien d'aile latérale de siège est établi, et le système de maintien d'aile latérale de siège d'automobile est en outre commandé de manière précise au moyen de la caméra et du dispositif d'opération de traitement graphique, de telle sorte qu'un conducteur ou un passager reste toujours attaché et à l'aise lorsqu'une automobile tourne.
