Abstract
The device has a microprocessor by which the signals are processed by a Global positioning systemunit integrated or connected in the device. The data of the locally effective speed specifications are stored in the global positioning system unit. The controlling signals are generated for the speed control for a motor management system so that the performance setting of the engine is limited to maintain maximal speed limitation data with the help of the speed.
Description
[0001] Für den heutigen Autofahrer ist die Regelung der korrekten, zulässigen Geschwindigkeit zunehmend schwieriger, da mehrere Parameter hierzu dauernd überwacht werden müssen. Abwechselnd müssen die Strasse selbst, der Strassenverkehr, Verkehrsschilder aller Art und Ampeln, Fussgängerstreifen, Tafeln mit Änderungen von Geschwindigkeitsbeschränkungen sowie der Tachometer überblickt und überprüft werden. Beim Tachometer muss überdies ein kleiner Sektor von meist kaum 30[deg.] des Tachometers im Auge behalten werden, denn nur in einem so kleinen Sektor der Tachometerscheibe werden die meisten einzuhaltenden Geschwindigkeiten in einem Bereich von 30-80 km/h angezeigt.
[0002] Will man heute - bei einer immer höherer werdenden Dichte an Apparaten zur Geschwindigkeitskontrolle - zu keiner Zeit die korrekte Geschwindigkeit überschreiten, so kann man entweder kaum mehr dauernd korrekt fahren oder man muss Unterstützung erhalten, da mit den sehr häufigen Blicken auf den Tachometer die Aufmerksamkeit für die übrigen Vorgänge auf der Strasse leidet und daher gefährliche Situationen entstehen. Es kommt dazu, dass der heutige Autofahrer oft am Telefonieren ist, was ihn zusätzlich ablenkt und seine Aufmerksamkeit für Geschwindigkeitsbeschränkungen herabsetzt.
[0003] Die Aufgabe dieser Erfindung ist es deshalb, ein Gerät zum Einhalten von Geschwindigkeitslimiten beim Autofahren anzugeben, welches die Einhaltung der ortsabhängigen geltenden maximal zulässigen Geschwindigkeit automatisch ermöglicht, sodass ein Überschreiten derselben verunmöglich ist.
[0004] Die Aufgabe wird gelöst von einem Gerät zum Einhalten von Geschwindigkeitslimiten beim Autofahren, das einen Mikroprozessor einschliesst, mittels dessen die Signale von einem ins Gerät integrierten oder anzuschliessenden Global-Postioning-System-Gerät, in welchem die Daten der lokal geltenden Geschwindigkeitsbeschränkungen abgelegt sind, verarbeitbar sind, wobei daraus mindestens Steuersignale für einen Tempomaten für das Motormanagement generierbar sind, sodass mindestens die Leistungssetzung des Motors anhand der Geschwindigkeitsbeschränkungsdaten auf die einzuhaltende Maximalgeschwindigkeit begrenzbar ist.
[0005] Damit wird eine positionsabhängige Geschwindigkeitsregelung realisiert. Die Position wird über ein GPS ermittelt. Im selben GPS Empfänger ist zu jeder Position die zulässige Höchstgeschwindigkeit hinterlegt, wie das heute schon gang und gäbe ist. Die dort zulässige Höchstgeschwindigkeit wird jedoch bisher bloss optisch angezeigt und bei deren Überschreiten wird ein akustisches Warnsignal generiert, das ausserdem auf stumm (MUTE) gesetzt werden kann. Ein beschäftigter und mit Gesprächen oder dem Verkehrsgeschehen beanspruchter Fahrer mag dieses Signal leicht überhören. Wenn aber der Sollwert zuverlässig und automatisch einhaltbar ist, so sind Tempoüberschreitungen wirksam unterbunden.
[0006] Der zugehörige mit den generierten Signalen versorgte Tempomat kann in einer einfachsten Ausführung einzige eine präzise Regelung der jeweils maximalen Geschwindigkeit über die Leistungssetzung ausführen. In einer weitergehenden Ausführung kann der Tempomat auch die Bremsen des Fahrzeuges aktivieren. Das ist vor allem bei Fahrzeugen mit automatischen Getrieben nötig. Beim Abwärtsfahren bei stärkeren Neigungen rollt ein Wagen leicht über den zulässigen Geschwindigkeitsbereich hinaus und die blosse Gasreduktion vermag die Geschwindigkeit nicht unter der maximal zulässigen zu halten. Hier ist eine Bremsleistung nötig, entweder durch Herunterschalten oder durch aktives Bremsen oder beides zusammen.
In einfachster Form lässt sich ein Regelkreis erstellen, wonach die Bremse betätigt wird, sobald die Geschwindigkeit überschritten wird, und die erst weder gelöst wird, wenn die Geschwindigkeit eingehalten ist. In einer weitergehenden Ausführung kann der Mikroprozessor des Gerätes mit der automatischen Schaltung kombiniert werden, sodass eine Gangstufe heruntergeschaltet wird, sobald die Geschwindigkeit überschritten wird, und erst wieder in eine höherer Gangstufe geschaltet wird, wenn das Fahrzeug um einen einstellbaren Geschwindigkeitsbetrag pro Zeit langsamer wird.
[0007] Um den Autofahrer noch weiter zu entlasten ist es vorteilhaft, wenn der Abstand zum vorderen Fahrzeug auch gerade in den Temporegelkreis eingebaut wird. Hierzu verarbeitet der Mikroprozessor des Geräts die bei gewissen Fahrzeugen bereits vorhandene Radarabstandssignale und verarbeitet diese weiter, indem bei zu geringen Abständen das Auto automatisch durch Gaszurücknahme oder wenn nötig durch eine aktive Bremsung reduziert wird. Die Regelgrössen können hierbei stufenlos variiert werden, sodass trotz allem eine ausgewogene sanfte Fahrweise resultiert, ohne abrupte Geschwindigkeitskorrekturen.
[0008] Der Mikroprozessor, der die entsprechenden Signale verarbeitet, kann zusätzlich mit einem Mobiltelefonchip ausgerüstet sein, der aus dem Internet Updates für die GPS Datenbasis downloaden kann. Eine weitere Ausbaumöglichkeit liegt in der Fähigkeit, via eine Tastatur im Auto E-Mails zu bearbeiten oder im Internet zu surfen, aber auch Musik im MP3-Format auf die Stereoanlage des Autos herunterzuladen.
[0009] Die Grundvariante aber deckt die automatische Geschwindigkeitsbegrenzung ab. Der Wert für die lokal zulässige Höchstgeschwindigkeit aus dem GPS-Navigationsgerät wird als obere Begrenzung in die Fahrzeugelektronik eingespeist, die bei Erreichen dieses Wertes das Gas abregelt, oder wenn nötig sogar bremsen kann. Nur durch die Kick-down Funktion, also durch abruptes kräftiges Durchtreten des Gaspedals kann die Begrenzungsautomatik jederzeit dominiert werden.
For today's motorists, the regulation of the correct, permissible speed is increasingly difficult, since several parameters must be constantly monitored for this purpose. Alternately, the road itself, road traffic, traffic signs of all kinds and traffic lights, pedestrian stripe, panels with changes in speed limits and the speedometer must be surveyed and checked. The tachometer also has to keep track of a small sector, usually barely 30 °, of the speedometer, because only in such a small sector of the tachometer disc are most of the speeds to be kept within a range of 30-80 km / h.
Will you today - with an ever-increasing density of speed control devices - at no time exceed the correct speed, so you can either hardly ever drive correctly or you need support, as with the very frequent views of the speedometer the attention for the other processes on the road suffers and therefore dangerous situations arise. The result is that today's motorist is often on the phone, which also distracts him and reduces his attention to speed limits.
The object of this invention is therefore to provide a device for maintaining speed limits while driving, which automatically allows compliance with the locally-dependent maximum permissible speed, so that exceeding the same is imprecise.
The object is achieved by a device for maintaining speed limits while driving, which includes a microprocessor, by means of which the signals from an integrated or to be integrated into the device Global Postioning system device, in which the data of the locally applicable speed restrictions filed are, are processable, from which at least control signals for a cruise control for the engine management can be generated so that at least the power setting of the engine based on the speed limit data can be limited to the maximum speed to be maintained.
For a position-dependent speed control is realized. The position is determined by a GPS. In the same GPS receiver the permissible maximum speed is stored for each position, as it is already common practice today. However, the maximum speed allowed there is only visually displayed and when it is exceeded an audible warning signal is generated, which can also be set to MUTE. A busy and busy with conversation or the traffic driver may easily ignore this signal. But if the setpoint is reliably and automatically maintainable, then tempo overruns are effectively prevented.
The associated with the generated signals cruise control can perform a precise control of each maximum speed on the power setting in a simplest embodiment only. In a further embodiment, the cruise control can also activate the brakes of the vehicle. This is especially necessary for vehicles with automatic transmissions. When driving downhill at higher inclinations, a car slightly rolls over the allowable speed range and the mere reduction of gas can not keep the speed below the maximum allowable. Here a braking power is needed, either by downshifting or by active braking or both together.
In the simplest form, a loop can be created, after which the brake is actuated as soon as the speed is exceeded, and which is not released until the speed is maintained. In a further embodiment, the microprocessor of the device can be combined with the automatic circuit, so that a gear is downshifted as soon as the speed is exceeded, and only switched to a higher gear when the vehicle slows down by an adjustable speed amount per time.
To relieve the driver even further, it is advantageous if the distance to the front vehicle is also installed just in the Temporegelkreis. For this purpose, the microprocessor of the device processes the radar distance signals already present in certain vehicles and processes them further by reducing the car automatically by gas withdrawal or, if necessary, by active braking if the distances are too short. The controlled variables can be infinitely varied so that, despite everything, a balanced, smooth driving style results, without abrupt speed corrections.
The microprocessor, which processes the corresponding signals, may additionally be equipped with a mobile phone chip that can download updates from the Internet for the GPS database. Another option is the ability to edit e-mails via a keyboard in the car or to surf the Internet, but also download music in MP3 format on the car stereo.
The basic variant but covers the automatic speed limit. The value for the locally permissible maximum speed from the GPS navigation device is fed as an upper limit into the vehicle electronics, which regulates the gas when it reaches this level, or even can brake it if necessary. Only through the kick-down function, ie by abrupt vigorous passage of the accelerator, the automatic limiting can be dominated at any time.
