Bei Fahrzeugen, welche eine automatische Öffnung der Heckklappe des Fahrzeuges aufweisen, besteht das Problem, dass die Heckklappe durch die automatische Öffnung beschädigt werden kann, wenn die automatische Öffnung derselben erfolgt, obwohl sich im Nahbereich des Fahrzeuges störende Objekte, wie zum Beispiel andere Fahrzeuge oder dergleichen, befinden. Es besteht somit die Gefahr, dass beim Öffnen der Heckklappe, welches nicht von Hand durch den Benutzer ausgeführt wird, sondern von einer Automatik des Fahrzeuges ausgelöst wird, die Heckklappe gegen andere Objekte oder Gegenstände stößt und dabei beschädigt wird. Diese Gefahr ist umso größer, wenn die Heckklappe in einem Bereich liegt, welcher von einem Fahrer des Fahrzeuges nicht vollständig einsehbar ist, wie es bei Heckklappen eines Personenkraftfahrzeuges der Fall ist. Auch wenn der Fahrer vor einem Betätigen der automatischen Öffnungseinrichtung sich durch rückwärtiges Blicken von seinem Fahrersitz aus vergewissert, ob etwaige Objekte im Weg sind, kann es dabei dennoch vorkommen, dass im nicht sichtbaren Bereich sich störende Objekte befinden und nach Betätigen der automatischen Öffnungseinrichtung die Heckklappe gegen diese stößt und beschädigt wird.For vehicles that have an automatic opening of the Have tailgate of the vehicle, there is the problem that the tailgate is damaged by the automatic opening if the automatic opening takes place, although objects in the vicinity of the vehicle, such as for example other vehicles or the like. It there is therefore a risk that when opening the tailgate, which is not carried out manually by the user, but is triggered by an automatic of the vehicle that Tailgate bumps into other objects or items and thereby being damaged. This danger is all the greater if the Tailgate is in an area by a driver of the vehicle is not fully visible, as is the case with Tailgates of a passenger car is the case. Also if the driver operates the automatic Opening device by looking back from his Driver's seat ensures that there are no objects in the way, it can still happen that in the invisible Objects are in the area and after pressing the automatic opening device the tailgate against this bumps and gets damaged.

Hierdurch kann die automatische Öffnung der Heckklappe durch die Öffnungseinrichtung derart gesteuert werden, dass bei Vorhandensein von störenden Objekten im Öffnungsbereich der Heckklappe die Öffnung unterbunden, gestoppt oder beeinflusst werden kann. Die Heckklappe kann somit nicht unbeabsichtigt beim Öffnen gegen Objekte stoßen, welche von dem Fahrzeughalter nicht gesehen werden. Ein unbeabsichtigtes Beschädigen der Heckklappe wird somit effektiv verhindert. Unter einer Steuereinheit wird erfindungsgemäß sowohl Steuergerät als auch eine Master-Slave Einheit, die ohne ein explizites Steuergerät auskommt, verstanden.According to the invention, this object is achieved by the vehicle surroundings monitoring system solved with the features of claim 1. This allows the automatic opening of the tailgate the opening device can be controlled such that at Presence of disturbing objects in the opening area of the Tailgate prevented, stopped or influenced the opening can be. The tailgate can not be accidentally hit objects that are opened by the Vehicle owners cannot be seen. An unintentional Damage to the tailgate is thus effectively prevented.

Alternativ dazu können die Sensoren auch im oberen Bereich des Rahmens einer Heckklappe, das heißt der Karosserie des Fahrzeuges, angeordnet sein. Beispielsweise können die Sensoren in dem Fahrzeughimmel im rückwärtigen Bereich einer Heckscheibe angeordnet sein, ähnlich wie die Zusatzbremsleuchten bei heutigen Personenkraftfahrzeugen. Dies hat den Vorteil, dass der Aufwand beim Installieren des Fahrzeugumfeldüberwachungssystems reduziert ist.According to a further advantageous embodiment of the invention the sensors are located in the tailgate. hereby the sensors when the tailgate opens automatically moved with their detection cone and it can still in the Automatic opening slowed down during the opening process or be stopped if, for example, only in last opening angle of the door itself is a disturbing object located. Alternatively, the sensors in the upper one Area of the frame of a tailgate, that is, the body of the vehicle. For example, the Sensors in the vehicle headlining in the rear area Rear window can be arranged, similar to the additional brake lights in today's passenger vehicles. This has the Advantage that the effort involved in installing the vehicle environment monitoring system is reduced.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Sensoren im oberen Bereich des Fahrzeuges angeordnet und weisen einen schräg nach unten gerichteten Erfassungsbereich bzw. -kegel auf. Hierdurch können vor allem Objekte im rückwärtigen Bereich des Fahrzeuges erfasst werden, welche beim Öffnen der Heckklappe stören, jedoch nicht durch den Fahrer von dem Fahrersitz des Fahrzeuges aus sichtbar sind.According to a further advantageous embodiment of the invention the sensors are located in the upper area of the vehicle and have an obliquely downward detection area or cone on. This allows objects in particular rear area of the vehicle are detected, which disturb when opening the tailgate, but not through the Drivers are visible from the driver's seat of the vehicle.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung umfassen die Sensoren Radar-, Ultraschall-, Laser, Infrarot und/oder Kamerasysteme. Entsprechend dem jeweiligen Erfassungsbereich bzw. Erfassungskegel der Sensoren können einer oder eine Mehrzahl von Sensoren in dem Bereich der Öffnung der Heckklappe vorgesehen sein.According to a further advantageous embodiment of the invention include the sensors radar, ultrasound, laser, infrared and / or camera systems. According to the respective Detection range or detection cone of the sensors can one or a plurality of sensors in the field of Opening of the tailgate may be provided.
