Description
Die Erfindung geht aus von einer Vorrichtung zur Unterstützung des Einparkens und/oder des Ausparkens eines Kraftfahrzeugs gemäß dem Oberbegriff des Anspruchs 1. Weiterhin betrifft die Erfindung ein Verfahren zur Unterstützung des Einparkvorgangs und/oder des Ausparkvorgangs eines Kraftfahrzeugs.The The invention is based on a device for supporting the Parking and / or the Ausparkens a motor vehicle according to the preamble of claim 1. Furthermore, the invention relates to a method for support the parking process and / or the Ausparkvorgangs a motor vehicle.
Üblicherweise weisen Kraftfahrzeuge eine gelenkte Achse und eine Antriebsachse auf. Hierbei wird unterschieden in Fahrzeuge mit Frontantrieb, bei denen die gelenkten Räder angetrieben werden und Fahrzeuge mit Heckantrieb. Zudem sind Fahrzeuge mit Allradantrieb am Markt erhältlich. Durch die Konzeption des Antriebs mit nur einer Antriebseinheit, die über eine Kardanwelle und ein Differenzialgetriebe die anzutreibenden Räder antreibt, sind mit dem Fahrzeug nur Kurven mit einem begrenzten Radius durchfahrbar. Dies führt auch dazu, dass beim Einparken eine Mindestgröße einer zur Verfügung stehenden Parklücke erforderlich ist, um das Fahrzeug mit überschaubarem Rangieraufwand in die Parklücke bewegen zu können. Zur Unterstützung des Einparkvorgangs werden zum Beispiel Abstandssensoren angeboten, mit denen jeweils der Abstand zu Hindernissen vor und hinter dem Fahrzeug ermittelt werden kann. Auch sind Sensoren am Markt, die die Größe der Parklücke abschätzen und den Fahrer durch Vorgabe des optimalen Einlenkeinschlages beim Einparken unterstützen oder sogar selbsttätig das Fahrzeug in eine vorhandene Parklücke einparken können. Jedoch erfordern alle diese Systeme auch die Vorgabe einer Mindestgröße für die Parklücke, da auch hier eine Verkleinerung des möglichen Radius beim Kurvenfahren nicht möglich ist.Usually Motor vehicles have a steered axle and a drive axle on. Here is a distinction in vehicles with front-wheel drive, at which the steered wheels driven and rear-wheel drive vehicles. There are also vehicles Available with four-wheel drive on the market. By designing the drive with only one drive unit, the above a propeller shaft and a differential gear to be driven Wheels drives, With the vehicle only curves with a limited radius are traversable. this leads to Also, when parking a minimum size of one available parking lot required to maneuver the vehicle with manageable maneuvering in the parking space to be able to move. For support of the parking procedure, for example distance sensors are offered, with each of which the distance to obstacles in front of and behind the Vehicle can be determined. There are also sensors on the market that estimate the size of the parking space and the Driver by specifying the optimal Einlenkeinschlages when parking support or even automatically Parking the vehicle in an existing parking space. however All these systems require the specification of a minimum size for the parking space, since also here a reduction of the possible radius when cornering not possible.
Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Eine erfindungsgemäße Vorrichtung zur Unterstützung des Einparkens und/oder des Ausparkens eines Kraftfahrzeugs umfasst mindestens zwei lenkbare Räder sowie mindestens zwei angetriebene Räder. Die angetriebenen Räder können jeweils unabhängig voneinander angetrieben werden, wobei die Räder mit unterschiedlichen Drehzahlen angetrieben werden können.A inventive device for support the parking and / or the Ausparkens a motor vehicle includes at least two steerable wheels and at least two driven wheels. The driven wheels can each independently are driven by each other, with the wheels at different speeds can be driven.
„Mit unterschiedlichen Drehzahlen angetrieben” im Sinne der vorliegenden Erfindung bedeutet, dass die Räder mit unterschiedlichen Drehzahlen in die gleiche Richtung oder auch in entgegengesetzter Richtung angetrieben werden können."With different Speeds driven "in Meaning of the present invention means that the wheels with different speeds in the same direction or even in opposite direction can be driven.
Durch die Möglichkeit, die angetriebenen Räder mit unterschiedlichen Drehzahlen anzutreiben, ist es möglich, dass das Fahrzeug einen kleineren Radius bei Kurvenfahrten durchfahren kann, als dies bei den aus dem Stand der Technik bekannten Antriebskonzepten möglich ist. Hierdurch ist zum Beispiel ein geringeres Einscheren beziehungsweise Ausscheren aus der Parklücke möglich und das Einparken kann erleichtert werden. Zudem kann das Fahrzeug mit weniger Rangieraufwand in eine kleinere Parklücke eingeparkt werden als dies bei den Fahrzeugen aus dem Stand der Technik möglich ist. Die unabhängig voneinander angetriebenen Räder können durch jedes beliebige Antriebskonzept angetrieben werden. Bevorzugt ist es jedoch, wenn die Antriebseinheit der Räder direkt im Bereich des Rades positioniert ist. Insbesondere ist es bevorzugt, zum Antrieb der unabhängig angetriebenen Räder Nabenmotoren einzusetzen. Die Nabenmotoren können dabei entweder als zusätzliche Motoren zu einem bereits bekannten und eingesetzten Antriebskonzept, beispielsweise einer Verbrennungskraftmaschine, verwendet werden, oder alternativ als einzige Antriebseinheit für das Kraftfahrzeug.By the possibility, the driven wheels With different speeds to drive, it is possible that Drive the vehicle a smaller radius when cornering can, than that in the known from the prior art drive concepts possible is. As a result, for example, a lower Einscheren or Ausscheren from the parking space possible and parking can be made easier. In addition, the vehicle can parked in a smaller parking space with less maneuvering be as possible in the vehicles of the prior art. The independently driven wheels can by Any drive concept can be driven. Is preferred However, if the drive unit of the wheels directly in the area of the wheel is positioned. In particular, it is preferable to drive the independently driven wheels hub motors use. The hub motors can either as an extra Engines to an already known and used drive concept, For example, an internal combustion engine to be used or alternatively as the only drive unit for the motor vehicle.
Üblicherweise werden Nabenmotoren als Elektromotoren ausgeführt. Die für die Versorgung des als Elektromotors ausgeführten Nabenmotors erforderliche Energie kann zum Beispiel bei Einsatz in einem Kraftfahrzeug mit Verbrennungskraftmaschine durch die Verbrennungskraftmaschine erzeugt werden. Bevorzugt ist es jedoch, die erfindungsgemäße Vorrichtung in Fahrzeugen mit Hybridantrieben, die einen Verbrennungsmotor und einen Elektromotor beziehungsweise Nabenmotor umfassen oder in Kraftfahrzeugen mit einem Elektroantrieb, der beispielsweise durch eine Brennstoffzel le oder durch aufladbare Akkumulatoren gespeist wird, einzusetzen. Auch in Kraftfahrzeugen, die eine Verbrennungskraftmaschine und mindestens einen Elektromotor umfassen, ist es möglich die Nabenmotoren zum Antrieb der Räder zusätzlich zum ursprünglichen Antriebskonzept oder als Ersatz für den bisher eingesetzten Elektromotor zu verwenden. Bei einem Elektroantrieb werden die Nabenmotoren vorzugsweise alternativ zu einem einzelnen Elektromotor, der die Antriebsenergie bereitstellt, eingesetzt. Jedoch ist es auch hier möglich, sowohl einen Elektromotor zum Antrieb des Fahrzeugs als auch unabhängig davon Nabenmotoren, mit denen der Einparkvorgang beziehungsweise der Ausparkvorgang unterstützt wird, zu verwenden. Bevorzugt ist es jedoch, die Nabenmotoren als einzige elektrische Antriebseinheit zu verwenden.Usually hub motors are designed as electric motors. The for the supply of as an electric motor executed Hub motor required energy can be used, for example in a motor vehicle with internal combustion engine by the internal combustion engine be generated. However, it is preferred that the device according to the invention in vehicles with hybrid drives that have an internal combustion engine and an electric motor or hub motor include or in motor vehicles with an electric drive, for example, by a Brennstoffzel le or powered by rechargeable accumulators. Also in motor vehicles, which is an internal combustion engine and At least one electric motor, it is possible the hub motors for Drive the wheels additionally to the original one Drive concept or as a replacement for the previously used electric motor to use. In an electric drive, the hub motors are preferably as an alternative to a single electric motor that drives the power provides used. However, it is also possible here, both an electric motor for driving the vehicle as well as independently Hub motors with which the parking or the Ausparkvorgang supports is going to use. However, it is preferred that the hub motors as to use only electric drive unit.
Der Einsatz von Nabenmotoren hat insbesondere den Vorteil, dass jedes Rad unabhängig von den anderen Rädern angetrieben werden kann. So ist es zum Beispiel möglich, die Räder mit gleicher Geschwindigkeit oder mit unterschiedlichen Geschwindigkeiten in die gleiche Richtung anzutreiben oder auch mit gleicher oder mit unterschiedlichen Geschwindigkeiten in entgegengesetzter Richtung anzutreiben. Insbesondere durch einen Antrieb der Räder in entgegengesetzte Richtung kann so ein sehr kleiner Wendekreis und damit ein platzsparendes Einparken ohne viele Rangiervorgänge in eine kleine Parklücke gewährleistet werden.The use of hub motors has the particular advantage that each wheel can be driven independently of the other wheels. For example, it is possible to drive the wheels at the same speed or at different speeds in the same direction or with the same or different Ge driving speeds in the opposite direction. In particular, by driving the wheels in the opposite direction so a very small turning circle and thus a space-saving parking can be guaranteed without many maneuvering into a small parking space.
Für den Antrieb des Fahrzeugs können zwei Räder oder auch vier Räder angetrieben sein. Die angetriebenen Räder befinden sich dabei üblicherweise an einer Achse des Fahrzeugs. Wenn zwei Räder angetrieben sind, so können dies bei zwei lenkbaren Rädern entweder die lenkbaren Räder oder die starren Räder sein. Neben zwei lenkbaren Rädern ist es weiterhin auch denkbar, dass vier Räder des Fahrzeugs lenkbar sind.For the drive of the vehicle two wheels or four wheels be driven. The driven wheels are usually on an axle of the vehicle. If two wheels are driven, so can with two steerable wheels either the steerable wheels or the rigid wheels be. In addition to two steerable wheels It is also conceivable that four wheels of the vehicle are steerable.
Um ein separates Ansteuern der jeweiligen Antriebseinheiten durch den Fahrer zu vermeiden, ist es weiterhin bevorzugt, wenn eine Steuereinheit umfasst ist, mit der anhand des Lenkradeinschlags die notwendigen Geschwindigkeiten der einzeln angetriebenen Räder ermittelt werden und die Antriebseinheiten der einzeln angetriebenen Räder entsprechend angesteuert werden.Around a separate control of the respective drive units by the To avoid drivers, it is further preferred if a control unit is included, with the basis of the steering wheel angle the necessary Speeds of individually driven wheels are determined and the Drive units of individually driven wheels driven accordingly become.
Um zu gewährleisten, dass ein entsprechender Antrieb der Räder nur beim Einparken beziehungsweise beim Ausparken oder bei Rangierparken erfolgt, ist es weiterhin bevorzugt, wenn der Steuereinheit beispielsweise durch eine Eingabe des Fahrers mitgeteilt wird, dass die folgenden Bewegungen des Fahrzeugs im Parkmodus erfolgen. Al ternativ ist es auch möglich, eine automatische Erkennung vorzusehen, die beispielsweise anhand der Geschwindigkeit des Lenkradeinschlags, der Fahrgeschwindigkeit oder anderer Parameter, die ein Einparken charakterisieren, erkennen, ob ein Einpark- oder Rangiervorgang erfolgt und entsprechend eine automatische Umstellung in den Einparkmodus erfolgt.Around to ensure, that a corresponding drive of the wheels only when parking respectively when parking or at Rangierparken done, it is still preferred when the control unit, for example, by an input the driver is informed that the following movements of the vehicle done in park mode. Alternatively, it is also possible to automatically detect provided, for example, by reference to the speed of the steering gear, driving speed or other parameters characterizing parking, recognize if a parking or maneuvering process takes place and according to an automatic conversion to the parking mode he follows.
Beim erfindungsgemäßen Verfahren zur Unterstützung des Einparkvorgangs und/oder des Ausparkvorgangs eines Kraftfahrzeugs, wobei das Kraftfahrzeug mindestens zwei lenkbare Räder und mindestens zwei unabhängig voneinander angetriebene Räder aufweist, werden in Abhängigkeit vom Lenkradeinschlag die unabhängig voneinander angetriebenen Räder unterschiedlich schnell oder bei Volleinschlag des Lenkrades in unterschiedlicher Richtung angetrieben.At the inventive method for support the parking process and / or the Ausparkvorgangs a motor vehicle, wherein the motor vehicle at least two steerable wheels and at least two independent powered wheels has, depending on from the steering wheel lock the independent driven wheels at different speeds or when the steering wheel is fully engaged in driven in different directions.
Durch das erfindungsgemäße Verfahren ist es möglich, aufgrund der unabhängig voneinander angetriebenen Räder, die auch in entgegengesetzter Richtung angetrieben werden können, das Kraftfahrzeug auch ohne umständliches Rangieren in kurze Parklücken einzuparken oder aus einer solchen herauszufahren.By the inventive method Is it possible, due to the independent wheels driven by each other, which can also be driven in the opposite direction, the Motor vehicle even without complicated Shunting into short parking spaces to park or drive out of such.
Das Verfahren ist vorzugsweise so gestaltet, dass mit zunehmendem Lenkradeinschlag die Geschwindigkeit des auf dem Innenkreis laufenden angetriebenen Rades zunächst bis zum Stillstand bei einem vorgegebenen Lenkradeinschlag abnimmt und danach bei weiter zunehmendem Lenkradeinschlag in entgegengesetzte Richtung zunimmt. Der Lenkradeinschlag, bei dem das auf dem Innenkreis laufende angetriebene Rad still steht, kann dabei abhängig sein von der Geschwindigkeit des Fahrzeuges. So wird bei zunehmender Geschwindigkeit der Lenkradeinschlag, und damit der Einschlag der lenkbaren Räder zunehmen, wohingegen bei niedrigerer Geschwindigkeit bereits bei einem kleineren Lenkradeinschlag ein Stillstand des auf dem Innenkreis laufenden angetriebenen Rades möglich ist. Hierdurch lässt sich der Einparkvorgang an die gewählte Geschwindigkeit anpassen.The Method is preferably designed so that with increasing steering wheel the speed of the driven on the inner circle driven Rades first decreases to a standstill at a given steering wheel angle and then with increasing steering wheel angle in opposite Direction increases. The steering wheel angle at which the running on the inner circle driven wheel stands still, it may depend on the speed of the vehicle. So, with increasing speed, the steering angle, and thus the impact of the steerable wheels increase, whereas at lower speed even with a smaller steering wheel angle a stoppage of running on the inner circle driven wheel possible is. This leaves the parking procedure is adapted to the selected speed.
Um den Einparkvorgang für den Fahrer zu vereinfachen, wird der Lenkradeinschlag und ein vom Fahrer vorgegebener Geschwindigkeitswunsch einer Steuereinheit als Eingangsgröße zugeführt, aus dem Lenkradeinschlag und dem Geschwindigkeitswunsch werden die notwendigen Geschwindigkeiten für die einzeln angetriebenen Räder ermittelt und die Antriebseinheiten für die Räder entsprechend angesteuert.Around the parking process for To simplify the driver, the steering wheel is turned and one of the Driver predetermined speed request of a control unit as Input supplied, off the steering wheel angle and the speed request are the necessary Speeds for the individually driven wheels determined and driven the drive units for the wheels accordingly.
Die Vorgabe des Geschwindigkeitswunsches durch den Fahrer erfolgt üblicherweise durch ein Fahrpedal. Jedoch ist es auch denkbar, den Geschwindigkeitswunsch über beliebige andere Vorrichtungen, beispielsweise auch handbetätigte Schalter vorzugeben.The Specification of the speed request by the driver is usually done through an accelerator pedal. However, it is also conceivable, the speed request on any specify other devices, for example, manually operated switch.
Die Geschwindigkeit für die einzeln angetriebenen Räder wird zum Beispiel über die Drehzahl der Nabenmotoren geregelt. Hierzu wird die Drehzahl des jeweils angetriebenen Rades gemessen und mit der für die erforderliche Geschwindigkeit notwendigen Drehzahl verglichen. Bei einer zu hohen gemessenen Drehzahl wird die Drehzahl reduziert entsprechend bei einer zu niedrigen gemessenen Drehzahl die Drehzahl erhöht.The Speed for the individually driven wheels is over for example the speed of the hub motors regulated. For this purpose, the speed of the each driven wheel and measured with the required Speed necessary speed compared. At too high a measured speed, the speed is reduced accordingly at a too low measured speed increases the speed.
