Abstract
Es wird eine Fahrgeschwindigkeitsregelung für ein Fahrzeug beschrieben, wobei ein Verlauf der Fahrgeschwindigkeit über der Zeit oder der Fahrstrecke aufgezeichnet wird und das zu einem späteren Zeitpunkt dieser aufgezeichnete Verlauf der Fahrgeschwindigkeit als Sollwert verwendet wird.A cruise control for a vehicle is described, wherein a course of the travel speed is recorded over time or the travel distance and the course of the travel speed recorded at a later point in time is used as a setpoint value.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Fahrgeschwindigkeitsregelung für ein Fahrzeug. Bei einer solchen Fahrgeschwindigkeitsregelung wird üblicherweise ein Istwert und ein Sollwert verglichen und abhängig von dem Vergleich eine Stellgröße vorgegeben, die die Fahrgeschwindigkeit des Fahrzeugs beeinflusst. The invention is based on a driving speed control for a vehicle. In such a vehicle speed control, an actual value and a setpoint value are usually compared and, depending on the comparison, a manipulated variable is predetermined which influences the driving speed of the vehicle.

Des Weiteren sind Geschwindigkeitsregelanlagen bekannt, bei den Umgebungseinflüssen mit umfangreicher Sensorunterstützung berücksichtigt werden. Hierbei werden insbesondere Kameras oder radargestützte Sensoren verwendet. Ferner kann vorgesehen sein, dass ein satellitenbasiertes System verwendet wird. Furthermore, cruise control systems are known in which environmental influences are taken into account with extensive sensor support. In particular, cameras or radar-based sensors are used. Furthermore, it can be provided that a satellite-based system is used.
Die im Folgenden beschriebene Lösung stellt eine Zwischenlösung zwischen dem einfachen Geschwindigkeitsregler und dem sehr aufwendigen Fahrgeschwindigkeitsregler dar. The solution described below represents an interim solution between the simple speed controller and the very elaborate cruise control.
In der Regel fährt der Fahrer bestimmte Fahrstrecken mehrmals. Umfasst diese Fahrstrecke mehrere Abschnitte, in denen der Fahrer unterschiedliche Fahrgeschwindigkeiten wünscht, muss er bei jeder Fahrt unterschiedliche Sollwerte für die einzelnen Abschnitte vorgeben.As a rule, the driver drives certain routes several times. If this route includes several sections in which the driver desires different speeds, he must specify different setpoints for the individual sections each time he drives.
Ziel der erfindungsgemäßen Vorgehensweise ist es dem Fahrzeugführer die erneute oder mehrfache Fahrt über die gleiche Strecke mit sich konstant änderndem Geschwindigkeitsprofil zu erleichtern, ohne dass er eingreifen bzw. hochpreisige Komfortsysteme verwenden muss. Insbesondere soll der Fahrverlauf beispielsweise durch Kurven oder bergauf/bergab Fahrten bzw. Geschwindigkeitsbegrenzungen berücksichtigt werden. The aim of the procedure according to the invention is to make it easier for the driver to repeat the journey over the same route with a constantly changing speed profile without having to intervene or using high-priced comfort systems. In particular, the course of the journey should be taken into account, for example, through bends or uphill / downhill journeys or speed limits.
Offenbarung der ErfindungDisclosure of the invention
Vorteile der Erfindung Advantages of the invention
Mit der erfindungsgemäßen Vorgehensweise ist es möglich, mehrfach gefahrene Strecken mit demselben Geschwindigkeitsprofil abzufahren. Hierzu wird für mehrfache oder gar häufig gefahrene Fahrstrecken ein Fahrprofil einmalig abgespeichert und kann dann mehrfach verwendet werden.With the procedure according to the invention, it is possible to travel on multiple routes with the same speed profile. For this purpose, a driving profile is stored once for multiple or even frequently traveled routes and can then be used several times.

In der Figur ist eine Fahrgeschwindigkeitsregelung für ein Fahrzeug dargestellt. Dabei sind nur die wesentlichen Elemente in der
Im Folgenden wird die Funktionsweise des Fahrgeschwindigkeitsreglers beschrieben. Bei der Istwertvorgabe handelt es sich vorzugsweise um einen Sensor der die Fahrgeschwindigkeit des Fahrzeugs ermittelt. Die Sollwertvorgabe
Das Bedienelement
Die obige Funktion entspricht der üblichen Funktion des Standes der Technik. Erfindungsgemäß werden nun weitere Funktionen des Bedienelements
Alternativ zu dem Istwert kann auch der im Sollwertspeicher
Wird der Istwert I aufgezeichnet, so hat dies den Vorteil, dass der Fahrer lediglich die Funktion „Aufzeichnen“ auswählt. Durch das Abfahren der Fahrstrecke mit der gewünschten Fahrgeschwindigkeit, kann das Profil für den Sollwert aufgezeichnet werden. Dadurch ist sehr einfach beliebige Profile mit komplexem Verlauf aufzuzeichnen. Nachteilig ist dabei, dass auch ungewollte Schwankungen, die durch äußere Einflüsse verursacht werden, mit aufgezeichnet werden.If the actual value I is recorded, this has the advantage that the driver merely selects the function "recording". By traversing the route with the desired travel speed, the profile for the target value can be recorded. This makes it very easy to record any profile with a complex course. A disadvantage is that even unwanted fluctuations that are caused by external influences are recorded.
Wird der Sollwert S, insbesondere das Ausgangssignal des Sollwertspeichers
Nimmt das Ausgangssignal B1 den Wert Abspielen an, so wird aus dem Verlaufsspeicher
