Description

Kraftfahrzeug mit seitlichem Umfeldsensor Beschreibung:Motor vehicle with lateral environment sensor Description:
Die Erfindung betrifft ein Kraftfahrzeug mit wenigstens einem Sensor zur Erfassung von Objekten in einem seitlichen Umfeld des Fahrzeugs, wobei der Sensor wenigstens einen Sender zum Aussenden elektromagnetischer oder akustischer Wellen sowie einen Empfänger zum Empfangen der an einem Objekt reflektier¬ ten elektromagnetischen oder akustischen Wellen aufweist.The invention relates to a motor vehicle having at least one sensor for detecting objects in a lateral environment of the vehicle, wherein the sensor has at least one transmitter for emitting electromagnetic or acoustic waves and a receiver for receiving the electromagnetic or acoustic waves reflected by an object.
Zur Unterstützung des Fahrers eines Kraftfahrzeugs und zur An¬ steuerung von Sicherungsmitteln ist es bekannt, Umfeldsensoren einzusetzen, mit denen insbesondere der Abstand zu Objekten, wie beispielsweise anderen Fahrzeugen bzw. Hindernissen be¬ stimmt werden kann. Die Sensoren sind dabei in der Regel als Radar-, Infrarot- oder Ultraschallsensoren ausgeführt, die über einen Sender verfügen, der elektromagnetische oder akus¬ tische Wellen aussendet, die von Objekten im Umfeld des Fahr¬ zeugs reflektiert werden. Der reflektierte Anteil der Wellen wird von einem Empfänger erfasst, wobei aus der Laufzeit der reflektierten Wellen der Abstand zu den Objekten bestimmt wer¬ den kann.In order to assist the driver of a motor vehicle and to control securing means, it is known to use environment sensors with which, in particular, the distance to objects, such as, for example, other vehicles or obstacles, can be determined. The sensors are generally designed as radar, infrared or ultrasonic sensors which have a transmitter that emits electromagnetic or acoustic waves that are reflected by objects in the vicinity of the vehicle. The reflected portion of the waves is detected by a receiver, wherein the distance to the objects can be determined from the transit time of the reflected waves.
Insbesondere ist es dabei bekannt, Umfeldsensoren zu verwen¬ den, die seitlich an dem Fahrzeug angeordnet sind und Objekte erfassen welche sich im Seitenbereich des Fahrzeugs befinden. Derartige Sensoren können verwendet werden, um einen seitli¬ chen Aufprall eines Objekts auf das Fahrzeug frühzeitig zu er¬ kennen und Sicherheitsmittel, wie beispielsweise Seitenairbags zu aktivieren. Ferner werden seitlich angeordnete Sensoren auch bei Systemen verwendet, die eine seitlich von dem Fahr¬ zeug angeordnete Parklücke erfassen.In particular, it is known to verwen the environment sensors, which are arranged laterally on the vehicle and detect objects which are located in the side region of the vehicle. Such sensors can be used to detect a side impact of an object on the vehicle at an early stage and to activate safety means, such as side airbags. Furthermore, laterally arranged sensors also used in systems that detect a laterally arranged by the Fahr¬ parking spot.
Derartige Sensoren sind in der Regel jedoch deutlich sichtbar und beeinträchtigen dadurch das äußere Erscheinungsbild eines Fahrzeugs .However, such sensors are usually clearly visible and thereby affect the appearance of a vehicle.
Es ist daher eine Aufgabe der vorliegenden Erfindung, einen Sensor zur Erfassung von Objekten im Seitenbereich eines Fahr¬ zeugs möglichst unauffällig seitlich an dem Fahrzeug anzuord¬ nen.It is therefore an object of the present invention to arrange a sensor for detecting objects in the lateral area of a vehicle as inconspicuously as possible laterally on the vehicle.
Erfindungsgemäß wird diese Aufgabe durch ein Kraftfahrzeug mit den Merkmalen des Patentanspruchs 1 gelöst.According to the invention, this object is achieved by a motor vehicle having the features of patent claim 1.
Nach der Erfindung ist es dabei vorgesehen, dass ein Kraft¬ fahrzeug der eingangs genannten Art so ausgeführt ist, dass der Sender und der Empfänger in einem Blinker angeordnet sind, der an einer Seitenwand des Kraftfahrzeugs angebracht ist, wo¬ bei der Sender und der Empfänger von einer Abdeckung des Blin¬ kers abgedeckt sind.According to the invention, it is provided that a motor vehicle of the type mentioned above is designed so that the transmitter and the receiver are arranged in a turn signal which is mounted on a side wall of the motor vehicle, wo¬ at the transmitter and the receiver are covered by a cover of the Blin¬ kers.
Auf diese Weise sind der Sender und der Empfänger des Sensors unauffällig in den Seitenblinker des Fahrzeugs integriert und führen zu keinerlei Beeinträchtigung seines äußeren Erschei¬ nungsbildes .In this way, the transmitter and the receiver of the sensor are inconspicuously integrated into the side indicator of the vehicle and do not lead to any impairment of its outer Erschei¬ nungsbildes.
Um eine einwandfreie Funktion des Sensors zu gewährleisten, ist es erforderlich, eine direkte Einstrahlung der Wellen von dem Sender in den Empfänger zu verhindern.To ensure proper operation of the sensor, it is necessary to prevent direct irradiation of the waves from the transmitter to the receiver.
In einer vorteilhaften Ausführungsform der Erfindung ist es daher vorgesehen, dass der Sender im Bereich eines Reflektors des Seitenblinkers und der Empfänger außerhalb des Reflektor¬ bereichs angeordnet ist, wobei eine Wand des Reflektors ein Trennelement zwischen dem Sender und dem Empfänger bildet.In an advantageous embodiment of the invention, it is therefore provided that the transmitter in the region of a reflector of the side indicator and the receiver is arranged outside the Reflektor¬ area, wherein a wall of the reflector forms a separating element between the transmitter and the receiver.
In einer weiteren, ebenso vorteilhaften Ausführungsform der Erfindung ist es alternativ vorgesehen, dass der Empfänger im Bereich des Reflektors des Seitenblinkers und der Sender au¬ ßerhalb des Reflektorbereichs angeordnet ist, wobei eine Wand des Reflektors ein Trennelement zwischen dem Sender und dem Empfänger bildet.In another, equally advantageous embodiment of the invention, it is alternatively provided that the receiver is arranged in the region of the reflector of the side indicator and the transmitter au¬ outside the reflector region, wherein a wall of the reflector forms a separating element between the transmitter and the receiver.
Durch eine Anordnung des Senders oder des Empfängers im Be¬ reich des Reflektors steht für das Leuchtmittel des Blinkers lediglich ein eingeschränkter Bauraum zur Verfügung.By arranging the transmitter or the receiver in the area of the reflector, only limited space is available for the illuminant of the turn signal.
Um dennoch eine ausreichende Leuchtstärke des Blinkers errei¬ chen zu können, ist in einer bevorzugten Ausgestaltung der Er¬ findung vorgesehen, dass im Bereich des Reflektors vorzugswei¬ se wenigstens eine Leuchtdiode zum Anzeigen von Richtungszei¬ chen angeordnet ist.In order nevertheless to be able to achieve a sufficient luminous intensity of the turn signal, it is provided in a preferred embodiment of the invention that at least one light-emitting diode for indicating directional signs is preferably arranged in the region of the reflector.
Aufgrund der geringen Einbaugröße von Leuchtdioden ist in die¬ ser Ausführungsform der Erfindung eine Anordnung des Senders oder des Empfängers sowie des Leuchtmittels im Bereich des Re¬ flektors möglich, ohne dass der Blinker die konventionellen Abmessungen überschreitet. Somit lassen sich die Einbauöffnun¬ gen für konventionelle Blinker für den Einbau des im Rahmen der Erfindung vorgesehenen Blinkers verwenden.Due to the small installation size of light emitting diodes in this embodiment of the invention, an arrangement of the transmitter or of the receiver and of the luminous means in the region of the reflector is possible without the turn signal exceeding the conventional dimensions. Thus, the Einbauöffnun¬ conditions for conventional turn signals for the installation of provided for in the invention turn signal can be used.
Um eine besonders gute Ausleuchtung der Reflektorfläche zu er¬ reichen, ist es vorzugsweise vorgesehen, dass der Sender oder Empfänger im Zentrum des Reflektors angeordnet und von wenigs¬ tens zwei Leuchtdioden umgeben ist. - A -In order to achieve a particularly good illumination of the reflector surface, it is preferably provided that the transmitter or receiver is arranged in the center of the reflector and surrounded by at least two light-emitting diodes. - A -
Die seitlichen Blinker eines Fahrzeugs und insbesondere der Reflektor eines solchen Blinkers haben in der Regel eine läng¬ liche Form. Eine gute Ausleuchtung des Reflektors kann dabei vorteilhaft insbesondere dadurch erreicht werden, dass jeweils eine Leuchtdiode seitlich von dem zentral angeordneten Sender oder dem zentral angeordneten Empfänger angebracht ist.The side indicators of a vehicle and in particular the reflector of such a turn signal usually have a Läng¬ Liche form. A good illumination of the reflector can be advantageously achieved in particular by the fact that in each case a light emitting diode is mounted laterally from the centrally located transmitter or the centrally located receiver.
Die Auswerteelektronik des Sensors ist in einer vorteilhaften Ausführungsform der Erfindung in einem Gehäuse des Blinkers untergebracht.The evaluation of the sensor is housed in an advantageous embodiment of the invention in a housing of the turn signal.
In einer bevorzugten Ausführungsform der Erfindung ist der Sensor als ein Infrarot-Sensor ausgebildet. In dieser Ausfüh¬ rungsform handelt es sich bei dem Sender vorzugsweise um eine im infraroten Spektralbereich emittierende Laserdiode. Bei dem Empfänger handelt es sich vorzugsweise um eine Empfangsdiode.In a preferred embodiment of the invention, the sensor is designed as an infrared sensor. In this embodiment, the transmitter is preferably a laser diode emitting in the infrared spectral range. The receiver is preferably a receiving diode.
Weitere Vorteile, Besonderheiten und zweckmäßige Weiterbildun¬ gen der Erfindung ergeben sich aus den Ausführungsbeispielen, die nachfolgend anhand der Figur 1 beschrieben werden.Further advantages, special features and expedient developments of the invention will become apparent from the exemplary embodiments which are described below with reference to FIG.
Fig. 1 zeigt dabei eine schematische Darstellung eines Seiten¬ blinkers für ein Fahrzeug mit einem integrierten Abstandssen¬ sor.1 shows a schematic representation of a side indicator for a vehicle with an integrated distance sensor.
Neben den im Front- und Heckbereich angeordneten Blinkern, de¬ ren Richtungszeichen insbesondere von voraus- oder hinterfah¬ renden Fahrzeugen aus sichtbar sind, verfügen Fahrzeuge in der Regel auch über Seitenblinker, die seitlich am Fahrzeug ange¬ ordnet sind und deren Richtungszeichen von beispielsweise von neben dem Fahrzeug befindlichen weiteren Fahrzeugen aus wahr¬ nehmbar sind. Die Seitenblinker sind dabei typischerweise im Bereich der seitlichen vorderen Kotflügel des Fahrzeugs ange¬ bracht und beispielsweise in einer länglichen Form mit abge¬ rundeten Stirnseiten ausgebildet, wobei sie in horizontaler Lage eingebaut sind.In addition to the indicators arranged in the front and rear areas, whose directional signs are visible, in particular, from vehicles ahead or behind, vehicles generally also have side indicators which are arranged laterally on the vehicle and whose directional symbols are, for example, from from further vehicles located next to the vehicle are perceivable. The side indicators are typically in the Ange¬ introduced region of the front side fender of the vehicle and formed, for example, in an elongated shape with abge¬ rounded front sides, where they are installed in a horizontal position.
Im Rahmen der Erfindung wird nun vorgeschlagen, einen Ab¬ standssensor in einen Seitenblinker des Fahrzeugs zu integrie¬ ren. Eine bevorzugte Ausgestaltung eines Seitenblinkers mit integriertem Abstandssensor ist dabei in Figur 2 dargestellt, und wird als Ganzes mit der Bezugsziffer 10 bezeichnet.In the context of the invention, it is now proposed to integrate a distance sensor into a side turn signal of the vehicle. A preferred embodiment of a side turn signal with integrated distance sensor is shown in FIG. 2, and is designated as a whole by the reference numeral 10.
Der Sensor an sich ist dabei in einer dem Fachmann bekannten Art ausgeführt. Er verfügt über einen Sender 15, welcher e- lektromagnetische oder akustische Wellen in einen bestimmten Beobachtungsraum aussendet. In dem Beobachtungsraum an einem Objekt reflektierte Wellen werden von einem Empfänger 20 er- fasst, so dass ein Vorhandensein von Objekten in dem Beobach¬ tungsraum erkannt werden kann. Aus der Laufzeit der reflek¬ tierten Signale kann der Abstand der Objekte von dem Fahrzeug ermittelt werden.The sensor itself is designed in a manner known to the expert. It has a transmitter 15 which emits electromagnetic waves or acoustic waves into a certain observation space. Waves reflected on an object in the observation space are detected by a receiver 20, so that a presence of objects in the observation space can be detected. From the duration of the reflected signals, the distance of the objects from the vehicle can be determined.

Bei dem Empfänger 20 handelt es sich um eine Empfangsdiode.In a preferred embodiment of the invention, the sensor is designed as an infrared sensor. As a transmitter 15 while a laser diode is used. The receiver 20 is a receiving diode.
Wie auch konventionelle Seitenblinker verfügt der erfindungs¬ gemäße Seitenblinker 10 über einen Reflektor 25 mit einer nach innen, d.h. in Richtung des Blinkergehäuses 30 gewölbten, lichtreflektierenden Oberfläche. Der Reflektor 25 weist dabei vorzugsweise eine Grundfläche in der Form eines länglichen Rechtecks mit abgerundeten Stirnseiten auf. Der Empfänger 20 ist bei der in Figur 2 dargestellten Ausges¬ taltung des Seitenblinkers 10 im Zentrum des Reflektors 25 an¬ geordnet. Als Leuchtquelle des Seitenblinkers 10 sind Leucht¬ dioden 35 vorgesehen, die sich aufgrund ihrer geringen Einbau¬ größe zusammen mit dem Empfänger 20 im Bereich des Reflektors 25 anordnen lassen.Like conventional side indicators, the side turn signal 10 according to the invention has a reflector 25 with a light-reflecting surface curved inwards, ie in the direction of the turn signal housing 30. The reflector 25 preferably has a base in the form of an elongated rectangle with rounded end faces. In the embodiment of the side indicator 10 shown in FIG. 2, the receiver 20 is arranged in the center of the reflector 25. As a luminous source of the side indicator 10 Leucht¬ diodes 35 are provided, which can be arranged together with the receiver 20 in the region of the reflector 25 due to their small Einbau¬ size.
Die Leuchtdioden dienen dabei zur Anzeigen von Richtungszei¬ chen und leuchten im angeschalteten Zustand in orangener Far¬ be.The light-emitting diodes serve to indicate directional signs and shine in the switched-on state in orange color.
Um eine gute Ausleuchtung des dargestellten länglichen Reflek¬ tors 25 zu ermöglichen, ist dabei jeweils eine Leuchtdiode 35 in Längsrichtung des Reflektors 25 vor und hinter dem Empfän¬ ger 20 angeordnet und in Querrichtung des Reflektors 25 vor¬ zugsweise mittig in dem Reflektor 25 positioniert. Durch diese Anordnung der Leuchtdioden 35 werden die beiden durch den Emp¬ fänger getrennten Bereiche der Längserstreckung des Reflektors 25 jeweils durch eine Diode 35 ausgeleuchtet. Insbesondere kann der Empfänger 20 dabei in einen Sockel mittig im Reflek¬ tor 25 integriert und die Leuchtdioden seitlich an dem Sockel angebracht sein.In order to allow a good illumination of the illustrated elongated Reflek¬ gate 25, in each case a light-emitting diode 35 in the longitudinal direction of the reflector 25 in front of and behind the Empfänger 20 gerän¬ and positioned in the transverse direction of the reflector 25 vor¬ preferably centrally in the reflector 25. As a result of this arrangement of the light-emitting diodes 35, the two regions of the longitudinal extension of the reflector 25 which are separated by the receiver are respectively illuminated by a diode 35. In particular, the receiver 20 can be integrated centrally in the reflector in the reflector and the light-emitting diodes can be attached laterally to the base.
Im Rahmen der Erfindung können jedoch selbstverständlich auch Seitenblinker 10 bzw. Reflektoren 25 verwendet werden, die nicht länglich ausgebildet sind, sondern eine andere Form auf¬ weisen, so dass andere Anordnungen des Empfängers 20 und der Leuchtdioden 35 zweckmäßig sind. Grundsätzlich sind dabei be¬ liebige Anordnungen des Empfängers und einer oder mehrerer Leuchtdioden denkbar.Within the scope of the invention, however, it is of course also possible to use side indicators 10 or reflectors 25, which are not elongated, but have a different shape, so that other arrangements of the receiver 20 and the light-emitting diodes 35 are expedient. In principle, be¬ arbitrary arrangements of the receiver and one or more light-emitting diodes are conceivable.
So kann es bei Seitenblinkern 10 bzw. Reflektoren 25 mit einer runden oder quadratischen Grundform beispielsweise vorgesehen sein, dass mehrere Leuchtdioden 35 auf dem Umfang eines Krei¬ ses angeordnet sind, in dessen Zentrum der Empfänger 20 posi¬ tioniert ist.For example, it can be provided with side indicators 10 or reflectors 25 with a round or square basic shape be that a plurality of light-emitting diodes 35 are arranged on the circumference of a Krei¬ ses, in the center of the receiver 20 is posi¬ tioned.
Der Sender 15 ist bei der in der Figur 2 dargestellten Ausges¬ taltung des erfindungsgemäßen Seitenblinkers 10 außerhalb des Reflektors 25 angeordnet und damit optisch von dem Empfänger 20 entkoppelt. Optische Entkopplung bedeutet dabei, dass eine direkte Einstrahlung des Senders 15 in den Empfänger 20 ver¬ hindert wird.In the embodiment of the side indicator 10 according to the invention shown in FIG. 2, the transmitter 15 is arranged outside of the reflector 25 and thus optically decoupled from the receiver 20. Optical decoupling means that direct irradiation of the transmitter 15 into the receiver 20 is prevented.
Bei dem in der Figur 2 dargestellten Seitenblinker 10 ist es vorgesehen, dass ein Trägerelement 40, in das der Reflektor 25 eingesetzt bzw. eingelassen ist, benachbart zu dem Reflektor 25 eine Ausnehmung aufweist, in welche der Sensor 15 einge¬ setzt ist, wobei die Ausnehmung sich bei der dargestellten länglichen Ausführungsform des Seitenblinkers 10 vorzugsweise an der Stirnseite des Seitenblinkers 10 befindet.In the side indicator 10 shown in Figure 2, it is provided that a support member 40, in which the reflector 25 is inserted or inserted, adjacent to the reflector 25 has a recess into which the sensor 15 is set einge¬, wherein the Recess in the illustrated elongated embodiment of the side indicator 10 is preferably located on the front side of the side indicator 10.
Zwischen dem Sender 15 und dem Empfänger 20 bildet sich somit ein Trennelement 45 aus, das senderseitig aus der dem Reflek¬ tor 25 zugewandten Wand der Ausnehmung und empfängerseitig aus der Wand des Reflektors 25 besteht und eine Entkopplung zwi¬ schen dem Sender 15 und dem Empfänger 20 sicherstellt.Thus, between the transmitter 15 and the receiver 20, a separating element 45 is formed, the transmitter side of which the reflector tor 25 facing wall of the recess and receiver side of the wall of the reflector 25 and a decoupling zwi¬ tween the transmitter 15 and the receiver 20 ensures.
Von außen wird der Seitenblinker 10 durch eine transparente Abdeckung 50 abgedeckt, die auf das Trägerelement 40 aufge¬ steckt wird, und die Vorderseite des Trägerelements 40, d.h. insbesondere die den Sender 15 aufnehmende Ausnehmung sowie den Reflektor 25 abdeckt. Die Abdeckung 50 kann dabei bei¬ spielsweise aus lichtdurchlässigem Kunststoff oder Glas gefer¬ tigt sein. Die elektrischen Anschlüsse des Senders 15, des Empfängers 15 sowie der Leuchtdioden 35 befinden sich an der Rückseite des Trägerelements 40 bzw. des Reflektors 25 und ermöglichen es, diese Bauteile signalmäßig mit einer Ansteuer- und Auswert¬ elektronik zu verbinden, die auf einer Platine 55 unterge¬ bracht ist, auf der auch die Elektronik des Blinkers 10 ange¬ ordnet ist, die insbesondere die Leuchtdioden 35 ansteuert. Die Elektronik des Senders 15 kann ebenfalls auf der Platine 55 oder in einem weiteren Bauteil 60 untergebracht sein, das ebenfalls im rückwärtigen Bereich des Trägerelements 40 ange¬ ordnet ist.From the outside, the side indicator 10 is covered by a transparent cover 50, which is plugged onto the carrier element 40, and covers the front side of the carrier element 40, ie in particular the recess receiving the transmitter 15 and the reflector 25. The cover 50 can bei¬ example, be made of translucent plastic or glass gefer¬. The electrical connections of the transmitter 15, the receiver 15 and the light-emitting diodes 35 are located on the rear side of the carrier element 40 and the reflector 25 and make it possible to connect these components signal-wise with a control and Auswert¬ electronics that on a board 55th unterge¬ is introduced, on which also the electronics of the turn signal 10 ange¬ is arranged, which controls in particular the light-emitting diodes 35. The electronics of the transmitter 15 can likewise be accommodated on the circuit board 55 or in a further component 60, which is likewise arranged in the rear region of the carrier element 40.
Zur Aufnahme der Platine verfügt der Seitenblinker 10 über Blinkergehäuse 30, auf welches das Trägerelement 40 aufge¬ steckt wird.For receiving the board, the side indicator 10 has turn signal housing 30, on which the carrier element 40 is inserted.
Je nach Art und Funktion des Senders und Empfängers kann der erfindungsgemäße Abstandssensor für verschiedene Einsatzzwecke verwendet werden. So kann der Sensor beispielweise zur Überwa¬ chung des sogenannten "toten Winkels" des Fahrzeugs verwendet werden, wobei ein Warnsignal ausgelöst werden kann, wenn bei einem Spurwechsel, der beispielsweise anhand des Einschaltens des Blinkers durch den Fahrer ermittelt wird, ein Objekt in dem toten Winkel erfasst wird.Depending on the type and function of the transmitter and receiver, the distance sensor according to the invention can be used for various purposes. Thus, the sensor can be used, for example, for monitoring the so-called "blind spot" of the vehicle, wherein a warning signal can be triggered if, during a lane change, which is determined, for example, by turning on the turn signal by the driver, an object in the dead Angle is detected.
Ferner kann der Sensor als ein sogenannter Pre-Crash-Sensor eines Insassenschutzsystems ausgebildet sein, der den seitli¬ chen Umfeldbereich des Fahrzeugs daraufhin überwacht, ob sich Objekte auf einem Kollisionskurs mit dem Fahrzeug befinden. Werden derartige Objekte erkannt, können Sicherheitsmittel, wie beispielsweise reversible Gurtstraffer oder ein Sitzver¬ stellungsmechanismus angesteuert werden, um die Fahrzeuginsas¬ sen bei einer Kollision zu schützen. Ferner können bereits vor dem ebenfalls mittels des Pre-Crash-Sensors ermittelbaren seitlichen Aufprall eines Objekts auf das Fahrzeug weitere Si¬ cherheitsmittel, wie beispielsweise Seitenairbags, ausgelöst werden.Furthermore, the sensor can be designed as a so-called pre-crash sensor of an occupant protection system which monitors the lateral surroundings of the vehicle to determine whether objects are in collision with the vehicle. If such objects are detected, safety means, such as, for example, reversible belt tensioners or a seat adjustment mechanism, can be actuated in order to protect the vehicle occupants in the event of a collision. Furthermore, already before the side impact of an object, which can also be detected by means of the pre-crash sensor, on the vehicle is triggered by further safety means, such as side airbags.
Darüber hinaus kann ein derartiger Sensor auch vorteilhaft bei einer Einparkhilfe eingesetzt werden, um eine Parklücke zu i- dentifizieren und zu vermessen. Dabei kann es beispielsweise vorgesehen sein, dass beim Vorbeifahren an einer Parklücke der seitliche Abstand zu Objekten mittels des Sensors ermittelt wird. Die Parklücke wird dabei als der Bereich identifiziert, in dem der Abstand zwischen dem Fahrzeug und seitlichen Objek¬ ten größer ist als in weiteren Bereichen, in denen die Objek¬ te, wie etwa andere Fahrzeuge, angeordnet sind, welche die Parklücke begrenzen. Anhand der Signale von Raddrehzahlsenso¬ ren des Fahrzeugs kann dabei die während des Passierens des Bereichs mit dem größeren Abstand zu den seitlich von dem Fahrzeug befindlichen Objekten zurückgelegte Wegstrecke und damit die Länge der Parklücke ermittelt werden. In addition, such a sensor can also be advantageously used in a parking aid in order to identify and measure a parking space. It can be provided, for example, that when driving past a parking space, the lateral distance to objects is determined by means of the sensor. The parking space is thereby identified as the area in which the distance between the vehicle and lateral objects is greater than in other areas in which the objects, such as other vehicles, are arranged, which delimit the parking space. On the basis of the signals of Raddrehzahlsenso¬ ren of the vehicle while the distance traveled during the passage of the area with the greater distance to the objects located laterally from the vehicle and thus the length of the parking space can be determined.
