Abstract

The invention serves to avoid dangerous situations in commercial traffic and reduce the number of accidents. The commercial driver no longer has to rely on subjective estimations but rather receives concrete information in order to adjust his driving style. The system is of modular design and can supply the following information depending on requirements and on its use: 1. the degree of positive or negative incline, 2. the appropriate travel speed as a result of this, 3. acoustic warning when the calculated speed is exceeded, 4. automatic reduction of speed or increase in power, 5. calculation of the instantaneous braking distance and thus safety distance. <IMAGE>

Description

Die Erfindung betrifft eine Meßeinrichtung zum Erkennen von Gefällen und Steigungen im Straßennetz in % für die Berufskraftfahrt. Die Einrichtung soll dem Fahrer die gefühlsmäßige Einschätzung von Gefällsituationen und angepaßter Geschwindigkeit abnehmen und ihm faktische Informationen liefern.The invention relates to a measuring device for recognizing slopes and gradients in the road network in% for professional driving. The device is intended to give the driver an emotional assessment of Slope situations and adapted speed decrease and him provide factual information.

Dabei ist die Einrichtung als Modulsystem aufgebaut, das von reiner Information = Anzeige der Neigung der Straße, über die Anzeige der möglichen Geschwindigkeit zur Warnfunktion = Signal, bis hin zum aktiven Eingreifen auf die Fahrgeschwindigkeit beinhalten kann.The facility is built as a modular system, that of pure Information = display of the slope of the road, via the display of the possible speed to the warning function = signal up to may involve active intervention in driving speed.

Bekannt ist, daß der Anteil der Berufskraftfahrt auf öffentlichen Straßen sehr hoch ist und daß es immer wieder zu schweren Unfällen, speziell in Gefällstrecken kommt, da die Geschwindigkeit und der damit verbundene Bremsweg bei schweren Fahrzeugen falsch eingeschätzt wurde.It is known that the share of professional driving on public Roads is very high and that there are always serious accidents, comes downhill especially because of the speed and the associated braking distance incorrectly assessed for heavy vehicles has been.

Es gibt bislang keine konkrete Information über die Neigungsstärke der Straße und die damit verbundene sinnvolle Höchstgeschwindigkeit für Kraftfahrer. Der Fahrer ist auf subjektive Schätzwerte angewiesen, speziell auf Landstraßen.So far there is no concrete information about the inclination strength the road and the associated sensible top speed for drivers. The driver is dependent on subjective estimates, especially on country roads.

Ob der Gefährlichkeit einer solchen Falscheinschätzung müssen hier genauere Informationsmöglichkeiten her.Whether the danger of such a misjudgment must be here more precise information.

Lösung Fig. 1Solution Fig. 1

Diese Aufgabe wird erfindungsmäßig dadurch gelöst, daß an einer beliebigen Stelle des Führerhauses eines Nutzfahrzeuges ein Nei­ gungsmesser (1) eingebaut wird.This object is achieved according to the invention in that a tilt meter ( 1 ) is installed at any point in the cab of a commercial vehicle.

Der ermittelte Grad der Neigung = Steigung oder Gefälle, wird an ein Anzeigeinstrument (2) im Cockpit weitergeleitet und dort in % ange­ zeigt. Diese Grundinformation des Fahrers entspricht Anspruch 1.The determined degree of inclination = incline or descent is forwarded to a display instrument ( 2 ) in the cockpit and displayed there in%. This basic information of the driver corresponds to claim 1.

Wird dieses Anzeigeinstrument (2) mit einem Rechnermodul (3) kombiniert, so kann der Rechner (3) aus Gefälle und Fahrzeuggewicht die angepaßte Geschwindigkeit errechnen.If this display instrument ( 2 ) is combined with a computer module ( 3 ), the computer ( 3 ) can calculate the adapted speed from the gradient and vehicle weight.

Dazu ist nötig, daß beim Einbau der Geräte die Neigungsanzeige (2) mittels eines Stiftes und dem Justierschalter (6) auf Null justiert wird, dabei muß das Fahrzeug auf einer ebenen Fläche stehen. Diese Justierung erfolgt nur einmal, sowie vor Fahrtantritt das tatsächliche Gesamtgewicht des Fahrzeuges in den Rechner (3) eingegeben wird (in Tonnen).For this it is necessary that the inclination indicator ( 2 ) is adjusted to zero by means of a pin and the adjustment switch ( 6 ) when installing the devices. The vehicle must stand on a level surface. This adjustment is made only once, as well as the actual total weight of the vehicle is entered into the computer ( 3 ) before the start of the journey (in tons).

Auf dem Anzeigeinstrument (2) erscheint die Art des Gefälles, auf dem Rechnermodul (3) die mögliche Geschwindigkeit. Dies entspricht dem Anspruch 2.The type of gradient appears on the display instrument ( 2 ) and the possible speed on the computer module ( 3 ). This corresponds to claim 2.

Der Rechner (3) hat zwei Eingänge und zwei Ausgänge. Der eine Ausgang ist die Anschlußmöglichkeit eines Warnsummers (4). Wird die errechnete Geschwindigkeit um mehr als 5 km/h überschritten, ertönt ein deutlicher Warnton, der den Fahrer akustisch informiert, daß er für die gegebene Straßenneigung zu schnell fährt. Dies entspricht Anspruch 3. The computer ( 3 ) has two inputs and two outputs. One output is the possibility of connecting a warning buzzer ( 4 ). If the calculated speed is exceeded by more than 5 km / h, a clear warning tone sounds, which acoustically informs the driver that he is driving too fast for the given road gradient. This corresponds to claim 3.

Um die Information der tatsächlich gefahrenen Geschwindigkeit zu erhalten, muß der Rechner (3) an den Fahrtenschreiber oder den Tachometer (10) angeschlossen werden.In order to obtain the information of the speed actually driven, the computer ( 3 ) must be connected to the tachograph or the tachometer ( 10 ).

Der zweite Ausgang (11) des Rechners (3) ist ein Impulsgeber für das Motormanagement (5). Die errechneten Daten lösen hier eine aktive Reaktion auf das Motormanagement aus = zum Beispiel Einschalten der Motorbremse, Abschalten der Kraftstoffzufuhr oder des Zündstromes, also Verringerung der Geschwindigkeit. Dieser Impulsgeber kann durch den Schalter (9) abgeschaltet werden.The second output ( 11 ) of the computer ( 3 ) is a pulse generator for engine management ( 5 ). The calculated data trigger an active reaction to the engine management = for example switching on the engine brake, switching off the fuel supply or the ignition current, i.e. reducing the speed. This pulse generator can be switched off by the switch ( 9 ).

Andererseits aber können mittels dieser Impulse auch leistungs­ fördernde Maßnahmen eingeleitet werden. So kann bei Turbomotoren der Ladedruck je nach Steigung automatisch erhöht werden, oder auch die Steuerzeiten der Ventile verändert werden, so daß an Steigungen we­ sentlich mehr Leistung zur Verfügung steht als auf der Ebene oder im Gefälle. Somit sind die Fahrzeuge an Steigungen wesentlich agiler und die Auffahrgefahr durch extrem langsame Fahrzeuge wird verringert. Dies entspricht Anspruch 4.On the other hand, these impulses can also perform promotional measures are initiated. So with turbo engines Boost pressure can be automatically increased depending on the slope, or even the Control times of the valves are changed so that we on slopes considerably more power is available than on the level or on the slope. This means that the vehicles are much more agile on slopes and the risk of collisions with extremely slow vehicles is reduced. This corresponds to claim 4.

Anstatt des Warnsummers (4) kann an den Rechner (3) ein weiteres Anzeigemodul (12) angeschlossen werden. Dieses zeigt den momentanen Bremsweg des Fahrzeuges an, den der Rechner (3) aus Gefälle, Fahr­ zeuggewicht und Geschwindigkeit errechnet hat. Dies entspricht Anspruch 5.Instead of the warning buzzer ( 4 ), a further display module ( 12 ) can be connected to the computer ( 3 ). This shows the current braking distance of the vehicle, which the computer ( 3 ) has calculated from the gradient, vehicle weight and speed. This corresponds to claim 5.

Die Gewichtsdaten des Fahrzeuges werden vor Fahrtantritt mit den Eingabetasten (7) und der Set-Taste (8) eingegeben.The weight data of the vehicle are entered with the enter keys ( 7 ) and the set key ( 8 ) before starting the journey.

Die Erfindung hat das Ziel, den allgemeinen Straßenverkehr sicherer zu machen, den Berufskraftfahrer zu entlasten und faktische Information zu liefern.The invention aims to make general road traffic safer to relieve the professional driver and factual information to deliver.
