Abstract
Description
Die Erfindung betrifft ein Informationssystem im Fahrzeug, wie eine Navigationsanlage mit satellitengestützter Ortung, die mit einem Display zur Darstellung der Navigationshinweise ausgestattet ist. Ferner betrifft sie Freisprecheinrichtungen, die mit einem Display ausgestattet, und entweder in der Navigationsanlage integriert oder eigenständig installiert sind.The The invention relates to an information system in the vehicle, such as a Navigation system with satellite-based positioning, which with a Display for displaying the navigation instructions is equipped. Further it concerns hands-free devices that are equipped with a display, and either integrated in the navigation system or installed independently.
Bei nächtlichen oder verdunkelten Lichtverhältnissen erscheinen die in Fahrzeugen eingesetzten Displays einem Fahrer wesentlich heller als bei Tageslicht, und können hierdurch das Befinden des Fahrers stören, seine Augen ermüden und somit eine Gefahrenquelle für den Straßenverkehr darstellen. Hierzu sind Lösungen bekannt, die verschiedene Hersteller praktizieren, wie z.B. eine manuelle Umschaltung bzw. Helligkeitsregelung auf eine helligkeitsreduzierte Displayausleuchtung, auf ein Nachtdesign, oder eine Farbeninvertierung. Die manuelle Umschaltung verlangt nachteilig nach einer Aktivität des Fahrers, die er häufig vergessen oder wegen eines ihm lästigen Aufwands unterlassen könnte.at night or darkened lighting conditions The displays used in vehicles appear to a driver much brighter than in daylight, and can thereby the health disturb the driver, his eyes are tired and thus a source of danger for the traffic represent. These are solutions known that practice various manufacturers, such. a Manual switching or brightness control to a reduced brightness Display illumination, on a night design, or a color inversion. The manual change disadvantageously requires an activity of the driver, he often forgotten or because of him annoying Expenses could refrain.
Aufgabe der vorliegenden Erfindung ist es, ein mit einem Display ausgestattetes Navigationssystem mit einer automatischen Helligkeitsanpassung auszustatten, die eine Anpassung an die äußeren Lichtverhältnisse ermöglicht, und hierzu möglichst bequeme, wirtschaftliche und zuverlässige Lösungen, und zusätzliche Nutzung der Signale des erfindungsgemäßen Systems im Fahrzeug vorzuschlagen.task It is the object of the present invention to provide a display equipped with a display Equip navigation system with an automatic brightness adjustment, the adaptation to the external light conditions allows and this as possible convenient, economical and reliable solutions, and additional To suggest use of the signals of the system according to the invention in the vehicle.
Erfindungsgemäß wird vorgeschlagen zunächst mit geeigneten Mitteln das Eintreffen einer abendlichen Dämmerung, bzw. einer morgendlichen Aufhellung zu erfassen, und dann eine geeignete Aktion auszulösen, in der die Intensität der Ausleuchtung des Displays angepasst wird.According to the invention is proposed first by appropriate means the arrival of an evening twilight, or a morning lightening, and then a suitable one Trigger action in the intensity the illumination of the display is adjusted.
Zum Erfassen einer Dämmerung oder Aufhellung wird vorgeschlagen einen lichtsensitiven Sensor einzusetzen, seine Messsignale auszuwerten, und beim Erreichen eines vorzugebenden Wertes den Vorgang auszulösen, in dem die Helligkeit der Displayanzeige angepasst wird. Es können mehrere Stufen durch mehrere Grenzwerte realisiert werden, oder gar eine direkte Abhängigkeit der Leuchtstärke des Displays von der gemessenen Außenlichtintensität umgesetzt werden. Diese Lösung bietet eine direkte Anpassung an die Lichtverhältnisse an, berücksichtigt die Wetterverhältnisse, um z.B. Verdunkelung durch Wolken oder sehr helle Lichtverhältnisse bei klarem Himmel und Sonnenschein, und bei Fahrten durch einen Tunnel auszugleichen. Der lichtsensitive Sensor kann ein intern in die Vorrichtung integrierter Sensor sein, oder es kann alternativ das Signal eines im Fahrzeug bereits vorhandenen Lichtsensors benutzt werden.To the Capturing a dawn or brightening is proposed a light-sensitive sensor to evaluate its measurement signals, and upon reaching a value to be given to initiate the process in which the brightness of the Display is adjusted. There may be several stages through several Limits are realized, or even a direct dependence the luminosity the display of the measured external light intensity implemented become. This solution offers a direct adaptation to the lighting conditions, taken into account the weather conditions, by e.g. Darkening by clouds or very bright lighting conditions in clear skies and sunshine, and when driving through one Balance tunnels. The light-sensitive sensor can be an internal be integrated into the device sensor, or it may alternatively Signal of a light sensor already in the vehicle used become.
Für alle vorgeschlagenen Lösungen gilt, dass das gewonnene Lichtanpassungssignal zusätzlich benutzt werden kann, um andere Systeme im Fahrzeug damit zu bedienen, so z.B. zum Ein- oder Ausschalten der Außenbeleuchtung des Fahrzeugs, falls der Fahrer es vergessen hat. Dies trifft man im Straßenverkehr häufig an, und es ist ein echtes Sicherheitsproblem, da ein unbeleuchtetes Fahrzeug von anderen Verkehrsteilnehmern leicht übersehen werden kann. Die manuelle Betätigung der Außenbeleuchtung durch den Fahrer und ihre Betätigung durch das erfindungsgemäße System sind dann in einer logischen Oder-Schaltung umsetzbar.For all proposed solutions is that the obtained Lichtanpassungssignal additionally used can be used to service other systems in the vehicle so e.g. to turn on or off the exterior lighting of the vehicle if the driver forgot. This one meets in traffic often and it's a real security problem since it's an unlit one Vehicle can easily be overlooked by other road users. The manual activity the exterior lighting by the driver and their operation through the system according to the invention are then implemented in a logical OR circuit.
Weiterhin kann das erfindungsgemäß gewonnene Signal über die Außenlichtverhältnisse extern aus dem Gerät herausgeführt und weiteren Anwendungen zur Verfügung gestellt werden, so z.B. um weitere Displays im Cockpit des Fahrzeugs ebenso in ihrer Lichtintensität anzupassen. Es können beispielsweise ein Display einer Freisprecheinrichtung, eines Radios oder die Instrumentenanzeige des Armaturenbretts sein.Farther can the invention obtained Signal over the external light conditions externally from the device led out and other applications, e.g. around to adjust other displays in the cockpit of the vehicle also in their light intensity. It can For example, a display of a speakerphone, a radio or the instrument panel of the dashboard.
Die durch das ermittelte Dämmerungsereignis auszulösende Aktion zur Anpassung der Lichthelligkeit des Displays kann durch verschiedene alternative Mittel umgesetzt werden. Zum einen wäre die Regelung der Helligkeit des Displays, in Stufen oder kontinuierlich, zum anderen das Umschalten eines Tag- und Nachtdesigns, sowie eine Farbinvertierung vorzuschlagen.The through the determined twilight event to be triggered Action to adjust the light brightness of the display can be through various alternative means are implemented. First, the scheme would be the brightness of the display, in stages or continuously, for to suggest to others the switching of a day and night design, as well as a color inversion.
Die Erfindung wird anhand einer vorteilhaften Ausführung erklärt.The Invention will be explained with reference to an advantageous embodiment.
