Abstract
Description
Die Erfindung betrifft eine Schalthilfe-Informationseinrich tung in Kraftfahrzeugen, bei denen Getriebeschaltvorgänge von Hand eingeleitet werden.The invention relates to a switching aid information device device in motor vehicles in which gear shift operations be initiated by hand.
Herkömmliche Drehzahlanzeigen bieten dem Fahrer kaum Infor mationen hinsichtlich bestimmter Fahrbetriebsweisen, z. B. kraftstoffverbrauchs- oder schadstoffemissionsoptimiert. Die Motordrehzahl gibt ansich weder Auskunft über den gegenwär tigen Betriebspunkt im Motorkennfeld noch über etwaige Dreh momentreserven nach einem Hochschalten in höhere Gänge.Conventional speed indicators hardly provide the driver with information mations regarding certain driving modes, e.g. B. optimized for fuel consumption or pollutant emissions. The Engine speed does not provide any information about the current operating point in the engine map still over any rotation Moments reserves after an upshift in higher gears.
Bei Fahrzeugen mit automatisierten Getrieben ist es bei spielsweise schon bekannt durch spezielle Verfahren den je weiligen Betriebspunkt des Motors im Kennfeld zu erfassen und unter bestimmten Bedingungen automatisch eine Schaltung in einen anderen Gang einzuleiten, so daß sich in solchen Fällen eine optimierte Kraftstoffausnutzung einstellen kann. Dabei ergibt sich jedoch das Problem der Notwendigkeit eines vorausschauenden Fahrens durch den Fahrer, was von elektro nischen Systemen nur mit relativ großem Aufwand gelöst werden kann. Andere Antriebssysteme, z. B. SAMT (Semi Automatic Ma nual Transmission) oder EPS (Elektro-Pneumatische Schaltung) haben nur die Möglichkeit, den Fahrer auf einer Anzeige an zuzeigen, welche Gänge er im Moment aufgrund eines zulässi gen Motordrehzahlbereiches schalten könnte.In vehicles with automated transmissions, it is at already known for example through special processes ever Detect the operating point of the engine in the map and automatically switching under certain conditions to enter another gear, so that in such Cases can set an optimized fuel economy. However, there arises the problem of the need for one predictive driving by the driver, what of electro African systems can only be solved with relatively great effort can. Other drive systems, e.g. B. SAMT (Semi Automatic Ma nual transmission) or EPS (electro-pneumatic circuit) only have the option of displaying the driver on a display show which gears he is currently on due to a permissible could switch to the engine speed range.
Bei Fahrzeugen mit handgeschalteten Gangwechseln sind als Pseudoschalthilfen schon sogenannte Ökonometer vorgesehen worden, die den momentanen Kraftstoffverbrauch digital oder analog oder symbolisiert darstellen. Eine echte Schalthilfe stellen diese Verbrauchsanzeigen jedoch nicht dar, dies um soweniger, je mehr Gänge mit dem vorhandenen Getriebe schaltbar sind. Gerade in Nutzfahrzeugen kommen heute moder ne Getriebe zur Anwendung, die eine Schaltung in beispiels weise 16 verschiedene Gänge ermöglichen.In vehicles with manual gear changes are as Pseudo-switching aids already provide economists been digital or the current fuel consumption represent analog or symbolized. A real switching aid however, these consumption indicators do not represent this less, the more gears with the existing transmission are switchable. Today, especially in commercial vehicles ne gearbox for use, a circuit in example enable 16 different gears.
Ausgehend von dieser Problematik ist es daher Aufgabe der Erfindung, bei Fahrzeugen mit von Hand einzuleitenden Schaltvorgängen Vorkehrungen zu treffen, die dem Fahrer eine verständliche und klar erkennbare Entscheidungshilfe zum Schalten bieten und eine kraftstoffverbrauchsoptimierte und/oder schadstoffemissionsminimierte Fahrweise fördern.Based on this problem, it is therefore the task of Invention to be initiated by hand in vehicles Gear changes to take precautions that give the driver a understandable and clearly recognizable decision support for Offer switching and a fuel consumption optimized and / or promote a driving style that minimizes pollutant emissions.
Diese Aufgabe wird erfindungsgemäß durch eine Schalthilfe- Informationseinrichtung mit den im Anspruch 1 angegebenen Merkmalen gelöst.According to the invention, this object is achieved by a switching aid Information device with those specified in claim 1 Features resolved.
Dabei ist eine Einrichtung zur visuellen oder akustischen Ausgabe einer Schaltempfehlung an den Fahrer und außerdem eine elektronische Recheneinrichtung vorgesehen, mit der auf der Basis erfaßter Istzustände von Motordrehzahl, Fahrge schwindigkeit, eingelegtem Gang, Fahrpedalstellung sowie auf der Basis von Daten der Motorcharakteristik und Getrie becharakteristik Werte für eine kraftstoffverbrauchsopti mierte und/oder abgasemissionsminimierte Fahrweise errechnet und in Signale für die Ausgabe entsprechender Schaltempfeh lungen an die eingangs erwähnte Einrichtung umgesetzt werden.There is a facility for visual or acoustic Output of a switching recommendation to the driver and also an electronic computing device is provided with which the basis of actual states recorded from engine speed, vehicle speed, gear engaged, accelerator pedal position and based on engine characteristics and transmission data characteristic values for a fuel consumption opt reduced and / or emissions-minimized driving style and in signals for the output of appropriate switching recommendations lungs to the facility mentioned at the beginning will.
Durch eine Gewichtung der Kriterien Kraftstoffverbrauch und Abgasschadstoffemission kann ein globales Optimum der Fahr weise erreicht werden. By weighting the criteria of fuel consumption and Exhaust emissions can drive a global optimum be achieved wisely.
Einzelheiten und mögliche Ausgestaltungen dieser erfindungs gemäßen Grundidee sind in den Unteransprüchen angegeben.Details and possible configurations of this fiction the basic idea is specified in the subclaims.
Unabhängig von der jeweils möglichen konkreten Ausführungs form bekommt der Fahrer immer ganz gezielt einen Hinweis, daß nach dessen Erscheinen ein Schalten angebracht ist.Regardless of the possible concrete execution the driver always gets a specific hint, that switching is appropriate after its appearance.
Nachstehend ist die erfindungsgemäße Lösung anhand mehrerer, in der Zeichnung dargestellter Ausführungsbeispiele noch nä her erläutert. In der Zeichnung zeigtThe solution according to the invention is based on several in the drawing shown embodiments nä ago explained. In the drawing shows

Zunächst sei nochmals kurz auf die der Erfindung zugrunde liegenden Problematik eingegangen. Was soll erreicht werden? Dem Fahrer soll klar gemacht werden, ob er beispielsweise im Teillastbereich in einem anderen Gang günstiger im Hinblick auf Kraftstoffverbrauch und/oder Abgasschadstoffabgabe fah ren könnte oder ob er im Vollastbereich auch in einem höhe ren Gang seine aktuelle Geschwindigkeit halten kann. In bei den Fällen kann dies nur dann sicher entschieden werden, wennTo begin with, the invention is briefly based again problem. What should be achieved? The driver should be made clear whether, for example, in the Partial load range in another gear cheaper in view on fuel consumption and / or emission of pollutants could be or whether it is at a height in the full load range gear can maintain its current speed. In at In cases this can only be decided with certainty if
- - das auf Kraftstoffverbrauchsoptimierung ausgelegte Motor kennfeld (Verbrauchskennfeld),- The engine designed to optimize fuel consumption map (consumption map),
- - das auf Abgasschadstoffminimierung ausgelegte Motorkenn feld (Abgasschadstoffkennfeld), - The engine code designed to minimize exhaust emissions field (exhaust emissions map),
- - aus diesen Motorkennfeldern die aktuelle Leistung und Leistungsreserve,- the current output and these engine maps Power reserve,
- - die verfügbaren Gangsprünge des Getriebes,- the available gear steps of the transmission,
- - die momentane Zuglast (resultierend aus Fahrzeuggewicht und befahrener Steigung) und damit die notwendige Leistung im jetzigen und späteren Gang,- the current tensile load (resulting from vehicle weight and driven incline) and thus the necessary performance in the current and later course,
- - die typische Schaltzeit des Fahrers (Zeitdauer zum Gangwechsel)- The typical switching time of the driver (time to Gear change)
- - der daraus resultierende Geschwindigkeitsverlust beim Schaltvorgang, und- The resulting loss of speed when Switching operation, and
- - aus den Motorkennfeldern sowie Gangsprüngen das nach einer Schaltung notwendige Drehmoment, um die gleiche Leistung bzw. die gleiche Beschleunigung wie vor der Schaltung zu erhalten,- from the engine maps as well as gear jumps after a Circuit necessary torque to get the same power or the same acceleration as before switching receive,
bekannt sind. Allein aus dem Wissen um Motordrehzahl, Fahr pedalstellung, dem eingelegten Gang, dem subjektiv empfunde nen Motorgeräusch und der sichtbaren Steigung der befahrenen Fahrstrecke wäre der Fahrer ohne besondere Konzentration nur unzureichend in der Lage, bei einem Getriebe mit einer Viel zahl von Schaltmöglichkeiten den optimalen Gang zu wählen.are known. From the knowledge of engine speed, driving alone pedal position, the gear engaged, the subjective feeling engine noise and the visible slope of the traffic The route would only be the driver without special concentration inadequate in a gearbox with a lot number of shift options to choose the optimal gear.
Um diese Unsicherheiten zu vermeiden, ist die erfindungsge mäße Schalthilfe-Informationseinrichtung vorgesehen. Diese besteht im Prinzip - siehe Fig. 1 - aus einer elektronischen Recheneinrichtung 1, die einen Mikroprozessor 2, Eingabeein heit 3, Ausgabeeinheit 4, Signalaufbereitungs- bzw. Signal wandlerstufen 5, 6, Programmspeicher 7, Arbeits- bzw. Daten speicher 8 aufweist, welche Teile durch Datenübertragungska näle 9 miteinander verknüpft sind.In order to avoid these uncertainties, the switching aid information device according to the invention is provided.

Im Arbeits- bzw. Datenspeicher 8 ist ein nach Gesichtspunk ten kraftstoffverbrauchsoptimierter Werte gegebenes Motor kennfeld des im Fahrzeug verwendeten Motors, z. B. Dieselmo tors, abgespeichert. Zweckmäßig ist es auch, wenn im Arbeits- bzw. Datenspeicher 8 auch ein nach Gesichtspunkten abgas schadstoffminimierter Werte gegebenes Motorkennfeld des be sagten Motors abgespeichert ist, auf das wahlweise zurückge griffen werden kann. Im Arbeits- bzw. Datenspeicher 8 ist außerdem datenmäßig die Charakteristik des dem betreffenen Motor nachgeschalteten Getriebes eingespeichert.In the working or data memory 8 is a given engine fuel consumption-optimized values engine map of the engine used in the vehicle, for. B. Diesel engine, stored. It is also expedient if an engine characteristic map of the engine in question, which is given from the point of view of emission-minimized values, is also stored in the working or data memory 8, and can optionally be used. In addition, the characteristic of the transmission connected downstream of the motor in question is stored in the working or data memory 8 .
In die Recheneinheit 1 werden während des Fahrbetriebes die Istzustände folgender von Sensoren bzw. Meßgeräten er faßten Istwerte eingeleitet, nämlich die Motordrehzahl n (erfaßt vom Sensor 10), die Geschwindigkeit v (von Geber 11), der momentane Kraftstoffverbrauch (von Meßgerät 12), die Stellung des Fahrpedals 13 (vom Geber 13/1), der Schaltzu stand des Getriebes (von Melder 14).The actual states of the following actual values detected by sensors or measuring devices are introduced into the computing unit 1 during driving operation, namely the engine speed n (detected by sensor 10 ), the speed v (by sensor 11 ), the current fuel consumption (by measuring device 12 ), the position of the accelerator pedal 13 (from the encoder 13/1 ), the Schaltzu stood the transmission (from detector 14 ).
Anhand dieser gemeldeten Istwerte und auf der Basis der Da ten der Motorcharakteristik (Motorkennfelder) und Getriebe charakteristik errechnet die Recheneinrichtung 1 mit ihrem Mikroprozessor 2 Werte für eine kraftstoffverbrauchsopti mierte Fahrweise (bei Rückgriff auf das kraftstoffverbrauchs optimierte Motorkennfeld) und/oder abgasschadstoffminimierte Fahrweise (durch Rückgriff auf das schadstoffminimierte Mo torkennfeld) und setzt diese errechneten Werte in Signale für die Ausgabe entsprechender Schaltempfehlungen an eine Ausgabe-Einrichtung 15 um.On the basis of these reported actual values and on the basis of the data of the engine characteristic (engine characteristics map) and transmission characteristic, the computing device 1 with its microprocessor 2 calculates values for a driving style optimized for fuel consumption (when using the engine characteristic chart optimized with fuel consumption) and / or driving style that minimizes exhaust gas emissions (through recourse) to the pollutant-minimized engine map) and converts these calculated values into signals for the output of corresponding switching recommendations to an output device 15 .
Von der elektronischen Recheneinrichtung 1 können bei der Berechnung der Schaltempfehlungen aber außer den erwähn ten Istwerten auch noch andere sich am Fahrzeug oder während des Fahrbetriebes ändernde Bedingungen, wie die aktuelle Be ladung, äußere Einflüsse wie Wind, Straßenzustände, Steigun gen bzw. Gefälle und dergleichen, berücksichtigt werden. Diese Bedingungen können teils durch zusätzliche Istzu standsmelder erfaßt oder intern anhand anderer Werte berech net werden.From the electronic computing device 1 when calculating the switching recommendations, however, in addition to the actual values mentioned, other conditions which change on the vehicle or during driving, such as the current loading, external influences such as wind, road conditions, gradients or gradients and the like , are taken into account. These conditions can be recorded in part by additional actual status indicators or can be calculated internally using other values.
Die Ausgabeeinrichtung 15 ist zur visuellen und/oder akusti schen Ausgabe einer Schaltempfehlung an den Fahrer einge richtet und in einem vom Fahrersitz aus einsehbaren Sichtbe reich, z. B. Armaturenbrett, oder im Umfeld des Fahrerarbeits platzes angeordnet.The output device 15 is for visual and / or acoustic output of a switching recommendation to the driver and is rich in a viewable from the driver's seat, such. B. dashboard, or in the area of the driver's work place.

Die Ausgabe-Einrichtung 15 und Drehzahlanzeige-Einrichtung 16, gegebenenfalls auch die Einrichtung 17, können zu einem An zeigeinstrument 18 vereinigt sein, wie in Fig. 1 angedeutet und in den Fig. 2 bis 9 beispielhaft dargestellt.The output device 15 and speed display device 16 , possibly also the device 17 , can be combined to form a display instrument 18 , as indicated in FIG. 1 and shown as an example in FIGS. 2 to 9.

Said light-emitting diode or lamp strip can be arranged at any point on the instrument panel or - as shown - extending along the pointer 19 thereon. For example, the pointer tip corresponds to the maximum available torque at the speed displayed. When all lighting elements are activated, i.e. lit, the driver uses 100% of the available torque. If only part of the light is on, it uses only part of the torque or the available power. This gives the driver an overview of the power reserves that he can then use by shifting up and down.
