Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Geschwindigkeitsregelung eines Fahrzeugs, wobei ein Ist-Abstand des Fahrzeugs zu einem vorherfahrenden Fahrzeug mittels eines Abstandsensors auf einen Soll-Abstand geregelt wird, wobei mittels des Abstandsensors ein anhaltendes, vorausfahrendes Fahrzeug detektierbar ist und das eigene Fahrzeug automatisch in den Stillstand abbremsbar und im Stillstand anhaltbar ist, dass bevor das Fahrzeug automatisch wieder angefahren wird, der Fahrer eine Wiederanfahrbestätigung durch Betätigung des Fahrpedals abgeben muss, wobei die Fahrpedalcharakteristik während des Stillstands verändert wird.The The present invention relates to a method and an apparatus for speed control of a vehicle, where an actual distance the vehicle to a preceding vehicle by means of a distance sensor is controlled to a desired distance, wherein by means of the distance sensor a persistent, preceding vehicle is detectable and the own vehicle can be braked automatically to a standstill and in Standstill is persistent, that before the vehicle automatically returns is approached, the driver a Wiederanfahrbestätigung by activity of the accelerator pedal, the accelerator pedal characteristic during the Standstill changed becomes.

Kern und Vorteile der ErfindungCore and advantages the invention
Der Kern der vorliegenden Erfindung ist es, dem Fahrer eines Fahrzeugs mit Staufolgeassistent einen intuitiven Schalter bereitzustellen, dass wenn die Wiederanfahrbedingungen für ein automatisches Wiederanfahren erfüllt sind, durch die Betätigung dem Staufolgeassistenten mitgeteilt wird, dass der Fahrer seine Aufmerksamkeit auf das Fahrgeschehen richtet und der Staufolgeassistent das Fahrzeug wieder anfahren kann. Erfindungsgemäß wird dieses durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen und Ausgestaltungen ergeben sich aus den Unteransprüchen.Of the The core of the present invention is the driver of a vehicle with Staufolgeassistent to provide an intuitive switch, that if the restart conditions for an automatic restart Fulfills are, by the operation of the Traffic control assistants are notified that the driver is paying attention on the driving events and the Staufolgeassistent the vehicle again can start. According to the invention this is through the characteristics of the independent Claims solved. advantageous Further developments and refinements emerge from the subclaims.
Vorteilhafterweise ist die Fahrpedalcharakteristik die Kennlinie der Momentenanforderung der Antriebseinrichtung in Abhängigkeit des Pedalwinkels des Fahrpedals. Im Sinne der vorliegenden Schrift ist unter der Momentenanforderung das vom Motor abzugebende Drehmoment gemeint, jedoch ist es auch möglich, die Leistungsabgabe des Motors zu bestimmen. Alternativ ist es auch möglich, anstatt dem Moment oder der Leistung den Soll-Betriebszustand des Motors in Form einer durch den Fahrer angeforderten Fahrzeugsollbeschleunigung vorzugeben. Im Rahmen der vorliegenden Erfindung umfasst der Begriff Momentenanforderung demzufolge entweder die Vorwahl eines abzugebenden Motormoments, die Vorwahl einer abzugebenden Motorausgangsleistung durch den Fahrer oder aber die Vorwahl einer Fahrzeugsollbeschleunigung durch den Fahrer.advantageously, the accelerator pedal characteristic is the characteristic curve of the torque request the drive device in dependence the pedal angle of the accelerator pedal. For the purposes of the present specification is under the torque request, the torque to be delivered by the engine meant, but it is also possible determine the power output of the engine. Alternatively it is possible, instead of the moment or the power the nominal operating state of the Engine in the form of requested by the driver vehicle target acceleration pretend. In the context of the present invention, the term comprises Torque request therefore either the area code of a to be delivered Engine torque, the preselection of engine output power to be delivered by the driver or the preselection of a vehicle target acceleration by the driver.
Weiterhin ist es vorteilhaft, dass die Fahrpedalcharakteristik im automatischen Stillstand so geändert wird, dass ein zum Anfahren erforderliches Motormoment erst bei größerem Fahrpedalwinkel erreicht wird, als bei der ungeänderten Pedalcharakteristik.Farther it is advantageous that the accelerator pedal characteristic in the automatic Standstill changed is that a required for starting engine torque only at larger accelerator pedal angle is reached, as with the unmodified Pedal characteristics.
Weiterhin ist es vorteilhaft, dass die Fahrpedalcharakteristik bei Erreichen des Stillstands geändert wird.Farther it is advantageous that the accelerator pedal characteristic when reaching changed from standstill becomes.
Besonders vorteilhaft ist es, dass die Veränderung der Fahrpedalcharakteristik bei Beendigung des Stillstands wieder rückgängig gemacht wird.Especially it is beneficial that the change the accelerator pedal characteristic at the end of the standstill again reversed becomes.
Von besonderer Bedeutung ist die Realisierung des erfindungsgemäßen Verfahrens in der Form eines Steuerelements, das für ein Steuergerät einer Abstandsregelung mit Staufolgefunktion eines Kraftfahrzeugs vorgesehen ist. Dabei ist auf dein Steuerelement ein Programm gespeichert, das auf einem Rechengerät, insbesondere auf einen Mikroprozessor oder Signalprozessor ablauffähig und zur Ausführung des erfindungsgemäßen Verfahrens geeignet ist. In diesem Fall wird also die Erfindung durch ein auf dem Steuerelement abgespeichertes Programm realisiert, so dass dieses mit dem Programm versehende Steuerelement in gleicher Weise die Erfindung darstellt, wie das Verfahren, zu dessen Ausführung das Programm geeignet ist. Als Steuerelement kann insbesondere ein elektrisches Speichermedium zur Anwendung kommen, beispielsweise ein Read-Only-Memory.From Of particular importance is the realization of the method according to the invention in the form of a control that is responsible for a distance control controller is provided with Staufolgefunktion a motor vehicle. there On your control is a program stored on a computing device, in particular executable on a microprocessor or signal processor and for execution the method according to the invention suitable is. In this case, so the invention by a on the program stored program realized so that this with the program providing control in the same way the Invention, as the method, the execution of which Program is suitable. As a control can in particular an electrical Storage medium are used, for example, a read-only memory.
