Abstract
Description
Die Erfindung betrifft eine Geschwindigkeitsregelanlage für ein Fahrzeug mit einem Fahrzeugmotor sowie ein Verfahren zur Geschwindigkeitsregelung eines Fahrzeugs.The invention relates to a cruise control system for a vehicle with a vehicle engine and a method for speed control of a vehicle.
Bekannte Geschwindigkeitsregelanlagen für Fahrzeuge sind so ausgelegt, dass eine einmal programmierte Geschwindigkeit unter nahezu allen Umständen gehalten wird, jedenfalls solange die maximal vom Antriebsmotor des Fahrzeuges lieferbare Leistung dazu ausreicht.Known cruise control systems for vehicles are designed so that a once programmed speed is maintained in almost all circumstances, at least as long as the maximum power available from the drive motor of the vehicle is sufficient.
Dies hat zur Folge, dass die Geschwindigkeitsregelanlage den Fahrzeugmotor so steuert, dass dessen Leistung, beispielsweise an Bergstrecken, so weit erhöht wird, dass die programmierte Geschwindigkeit des Fahrzeugs gehalten wird. Dies wiederum hat zur Folge, dass der Kraftstoffverbrauch bzw. Energieverbrauch des Antriebsmotors in diesen Situationen unnötig stark ansteigt.The result of this is that the speed control system controls the vehicle engine so that its power, for example on mountain routes, is increased to such an extent that the programmed speed of the vehicle is maintained. This in turn has the consequence that the fuel consumption or energy consumption of the drive motor unnecessarily increases in these situations.
Es ist Aufgabe der Erfindung, eine Geschwindigkeitsregelanlage der eingangs genannten Art anzugeben, welche den Fahrzeugmotor so steuert, dass dieser möglichst wenig Energie verbraucht.It is an object of the invention to provide a cruise control system of the type mentioned, which controls the vehicle engine so that it consumes as little energy.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, dass eine Steuerung der Geschwindigkeitsregelanlage so ausgelegt ist, dass sie die Geschwindigkeit des Fahrzeugs auf einer einstellbaren Soll-Geschwindigkeit hält sofern die Leistungsabgabe des Fahrzeugmotors eine einstellbare maximale Soll-Leistung nicht überschreitet, und dass sie die Geschwindigkeit des Fahrzeugs gegebenenfalls soweit reduziert, dass die maximale Soll-Leistung nicht überschritten wird.This object is inventively achieved in that a controller of the cruise control system is designed so that it keeps the speed of the vehicle at an adjustable target speed provided that the power output of the vehicle engine does not exceed an adjustable maximum target power, and that they are the speed of the vehicle if necessary reduced to the extent that the maximum target power is not exceeded.
Die erfindungsgemäße Geschwindigkeitsregelanlage arbeitet ähnlich einer bekannten Geschwindigkeitsregelanlage solange die vom Fahrzeugmotor einzusetzende Leistung eine vorgebbare maximale Soll-Leistung nicht überschreitet. Insoweit dies der Fall ist, wird also die eingestellte Soll-Geschwindigkeit gehalten.The speed control system according to the invention operates similar to a known cruise control system as long as the power to be used by the vehicle engine does not exceed a predefinable maximum target power. Insofar as this is the case, so the set target speed is maintained.
Ist es jedoch nicht (mehr) möglich, die eingestellte Soll-Geschwindigkeit zu halten und dabei die Leistungsabgabe des Fahrzeugmotors auf oder unter der maximale Soll-Leistung zu halten, so begrenzt die erfindungsgemäße Geschwindigkeitsregelanlage die vom Fahrzeugmotor abgegebene Leistung auf die Soll-Leistung und reduziert somit die Geschwindigkeit des Fahrzeugs.However, if it is not possible (more) to maintain the set target speed while keeping the power output of the vehicle engine at or below the maximum target power, the cruise control system according to the invention limits the power output by the vehicle engine to the desired power and reduces hence the speed of the vehicle.
Dies hat zwar zur Folge, dass eine eingestellte Soll-Geschwindigkeit ggf. nicht mehr gehalten werden kann; es tritt jedoch eine nicht unwesentliche Energieeinsparung beim Fahrzeugmotor auf, da dieser in einem günstigeren Arbeitspunkt betrieben werden kann und somit weniger Energie verbraucht als wenn er hinreichend Leistung zur Einhaltung der Soll-Geschwindigkeit abgeben müßte. Diese Energieeinsparung tritt vor allem an Steigungen auf, an denen die Leistungsbegrenzung auf die Soll-Leistung wirksam wird.Although this has the consequence that a set target speed may possibly no longer be maintained; However, there is a significant energy savings in the vehicle engine, since it can be operated in a lower operating point and thus consumes less energy than if it would have to give sufficient performance to comply with the target speed. This energy saving occurs mainly on gradients at which the power limitation to the target power is effective.
Diese sich ggf. aus der Leistungsbegrenzung auf die Soll-Leistung ergebende Differenz zwischen der tatsächlichen Geschwindigkeit und der Soll-Geschwindigkeit kann vorteilhaft begrenzt werden, so dass die Fahrzeuggeschwindigkeit nicht zu weit abfällt.This difference between the actual speed and the setpoint speed, possibly resulting from the power limitation to the desired power, can advantageously be limited so that the vehicle speed does not drop too far.
Dies kann vorteilhaft, wie gemäß Ausgestaltungen der Erfindung vorgesehen ist, dadurch gestaltet werden, dass die Anlage die Motorleistung so einstellt, dass die tatsächliche Geschwindigkeit die eingestellte Soll-Geschwindigkeit um nicht mehr als einen vorgebbaren Prozentwert oder um nicht mehr als eine vorgebbare Geschwindigkeitsdifferenz zur Soll-Geschwindigkeit unterschreitet. Somit hat ein Fahrzeugführer einen unmittelbaren oder mittelbaren Einfluß auf die maximale Abweichung der Ist-Geschwindigkeit von der Soll-Geschwindigkeit.This can be advantageous, as provided according to embodiments of the invention, characterized in that the system adjusts the engine power so that the actual speed of the set target speed by no more than a predetermined percentage or not more than a predetermined speed difference to the target Speed falls below. Thus, a driver has an immediate or indirect influence on the maximum deviation of the actual speed from the target speed.
Dieses Ziel kann vorteilhaft auch, wie gemäß weiteren Ausgestaltungen der Erfindung vorgesehen ist, dadurch erreicht werden, dass die Anlage die Reduktion der Geschwindigkeit so begrenzt, dass die tatsächliche Geschwindigkeit eine vorgebbare Mindestgeschwindigkeit nicht unterschreitet.This goal can also advantageously be achieved, as provided according to further embodiments of the invention, by the fact that the system limits the reduction of the speed so that the actual speed does not fall below a predefinable minimum speed.
Eine für einen Fahrzeugführer einfache und effektive Möglichkeit der Einstellung der Soll-Leistung besteht gemäß weiteren Ausgestaltungen der Erfindung darin, dass die einstellbare Soll-Leistung der Motorleistung entspricht, die der Fahrzeugmotor bei Aktivierung der Geschwindigkeitsregelanlage zum Einhalten einer aktuellen Geschwindigkeit abgibt, oder dass die einstellbare Soll-Leistung als Wert einstellbar ist.A simple and effective way for a driver of setting the target power is according to further embodiments of the invention is that the adjustable target power corresponds to the engine power that emits the vehicle engine when activating the cruise control system to maintain a current speed, or that the adjustable Target power is adjustable as a value.
Handelt es sich bei dem Fahrzeugmotor um einen Verbrennungsmotor, so ist die Leistung des Fahrzeugmotors mittels der Geschwindigkeitsregelanlage, wie nach einer weiteren Ausgestaltung der Erfindung vorgesehen ist, mittels geeigneter Einstellung einer Drosselklappenöffnung und/oder einer Einspritzmenge des Fahrzeugmotors vornehmbar.If the vehicle engine is an internal combustion engine, the power of the vehicle engine can be adjusted by means of the cruise control system, as provided according to a further embodiment of the invention, by means of suitable adjustment of a throttle valve opening and / or an injection quantity of the vehicle engine.
Wie bereits erläutert wurde, kann an Steigungsstrecken eine Differenz zwischen einer eingestellten Soll-Geschwindigkeit und der Ist-Geschwindigkeit eintreten. Um einen Fahrzeugführer auf eine solche Differenz aufmerksam zu machen, ist gemäß weiteren Ausgestaltungen der Erfindung vorgesehen, dass die Geschwindigkeitsregelanlage ein optisches und/oder akustisches Warnsignal abgibt, sobald die Soll-Geschwindigkeit nicht mehr eingehalten wird oder sobald die Soll-Geschwindigkeit um mehr als einen vorgebbaren Wert unterschritten wird.As already explained, a difference between a set desired speed and the actual speed can occur on uphill sections. In order to make a driver aware of such a difference, it is provided according to further embodiments of the invention that the cruise control system emits an optical and / or audible warning signal, as soon as the setpoint speed is no longer maintained or as soon as the setpoint speed is undershot by more than a predefinable value.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Es zeigen:An embodiment of the invention will be explained in more detail with reference to the drawing. Show it:
Die Geschwindigkeitsregelanlage weist eine Steuerung
Ein Fahrzeug, in dem sich die Geschwindigkeitsregelanlage befindet, ist mittels eines Fahrzeugmotors
Der Fahrzeugmotor
Nachfolgend wird die Arbeitsweise der Geschwindigkeitsregelanlage gemäß
Block A in
Ein Bediener kann gemäß Block B zwischen zwei Modi der Geschwindigkeitsregelanlage wählen:
- – Block C deutet eine konventionelle Arbeitsweise der Geschwindigkeitsregelanlage an, bei der auch an Steigungen eine einstellbare Soll-Geschwindigkeit soweit möglich gehalten wird. Dazu gibt die
Steuerung 1 der Geschwindigkeitsregelanlage in Abhängigkeit der vomSensor 7 bzw. derMotorsteuerung 6 signalsierten Ist-Geschwindigkeit entsprechende Signale an dieMotorsteuerung 4 . Durchfährt das Fahrzeug eine Steigungsstrecke, so erhöht dieSteuerung 1 der Geschwindigkeitsregelanlage die Motorleistung soweit, dass dennoch die Soll-Geschwindigkeit eingehalten wird. dabei erhöht sich der Energieverbrauch desFahreugmotors 3 deutlich. - – In
2 mittels Block D angedeutet, ist ein weiterer Modus wählbar, in welchem die Arbeitsweise derSteuerung 1 der Geschwindigkeitsregelanlage auf einen energiesparenden Betrieb einstellbar ist. Gegebenenfalls kann dieser Modus auch als einziger Modus vorgesehen sein. Dabei arbeitet dieSteuerung 1 so, dass sie die Geschwindigkeit des Fahrzeugs auf einer einstellbaren Soll-Geschwindigkeit hält, sofern die Leistungsabgabe des Fahrzeugmotors eine einstellbare maximale Soll-Leistung nicht überschreitet. Droht jedoch die Soll-Leistung überschritten zu werden, begrenzt dieSteuerung 1 mittels derMotorsteuerung 4 die Leistung des Motors3 auf die Soll-Leistung und reduziert somit Geschwindigkeit des Fahrzeugs gegebenenfalls soweit, dass die maximale Soll-Leistung nicht überschritten wird.
- - Block C indicates a conventional operation of the cruise control system, in which an adjustable target speed is kept as far as possible even on slopes. This is given by the
controller 1 the speed control system as a function of thesensor 7 or theengine control 6 signaled actual speed corresponding signals to theengine control 4 , If the vehicle passes through a gradient, the control increases1 The speed control system, the engine power so far that nevertheless the target speed is maintained. this increases the energy consumption of thedriving engine 3 clear. - - In
2 indicated by block D, another mode is selectable, in which the operation of thecontroller 1 the speed control system is adjustable to an energy-saving operation. Optionally, this mode may also be provided as a single mode. The controller works1 such that it keeps the speed of the vehicle at an adjustable target speed, provided that the power output of the vehicle engine does not exceed an adjustable maximum target power. However, the target performance is threatened to be exceeded, limits thecontrol 1 by means of theengine control 4 the power of theengine 3 to the target power and thus reduces speed of the vehicle if necessary so far that the maximum target power is not exceeded.
In dem erfindungsgemäßen energiesparenden Betrieb der Geschwindigkeitsregelanlage ist, angedeutet mittels des Blockes E, eine Begrenzung der Geschwindigkeitsreduktion bzw. der Leistungsreduktion wählbar. Vorteilhaft kann dabei eine maximale Abweichung zwischen der Ist-Geschwindigkeit (beispielsweise der Geschwindigkeit des Fahrzeugs bei Aktivierung der Steuerung
Ist die Steuerung
Dabei überprüft die Steuerung
Diese Reduktion der Motorleistung kann vorteilhaft, wie oben erläutert, begrenzt sein, so dass die Fahrzeuggeschwindigkeit nicht zu weit abfällt.This reduction in engine power can advantageously be limited, as explained above, so that the vehicle speed does not drop too far.
