Abstract

The system comprises two optical sensors (3) in the rear lights of the vehicle. They are operated on a pulsed basis, and incorporate a radiation transmitter and a receiver. The sensors are positioned at an angle to the vertical which prevents any effect of unwanted light on the receiver. The transmitter and receiver are directed in parallel, and are optically insulated from one another. The transmitter is set in operation by an impulse generator (2) which is started by a switch (1), e.g vehicle reversing lights. If an object is present in the radiation lobe, the reflected radiation from it reaches the receiver and is passed to a signal prepn. unit (4). This unit only amplifies high frequency signal components emitted by the transmitter, and passes them to a signal evaluator (5). Thus, if a min. distance between the rear of the object is not maintained, a warning signal light illuminates within view of the driver. USE/ADVANTAGE - To assist in safe parking of vehicles. Ensures min. distance from vehicle rear to object behind it.

Description

Die Erfindung bezieht sich auf eine Parkhilfe für Kraftfahr­ zeuge.The invention relates to a parking aid for motor vehicles witness.

In der Praxis ist das Einparken insbesondere von größeren Kraftfahrzeugen oft mit Schwierigkeiten verbunden, da das Fahr­ zeug insbesondere die Heckpartie von der Position des Fahrers meist nicht voll überblickt werden kann.In practice, parking is especially large Motor vehicles are often difficult because of driving the rear section in particular testifies to the position of the driver usually cannot be fully overlooked.

Ziel der vorliegenden Erfindung ist es, dem Fahrer eine Hilfe­ stellung während des Einparkvorganges in Form einer Abstands­ warneinrichtung zu geben.The aim of the present invention is to help the driver position during the parking process in the form of a distance to give warning device.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Parkhilfe ein Sensorsystem, welches einen Gegenstand oder ein Fahrzeug unter Berücksichtigung eines Mindestabstandes erfaßt, und eine elektronische Beschaltung, die ein geeignetes Warnsi­ gnal bei Unterschreitung des Mindestabstandes an den Fahrer gibt, beinhaltet.This object is achieved in that the Parking aid a sensor system, which is an object or a Vehicle is detected taking into account a minimum distance, and an electronic circuit, which is a suitable warning signal to the driver if the minimum distance is undershot there, includes.

Ein Ausführungsbeispiel eines entsprechenden Sensorsystems und dessen elektronischer Beschaltung, ist nachstehend beschrie­ ben, und in den Zeichnungen gezeigt.An embodiment of a corresponding sensor system and its electronic wiring is described below ben, and shown in the drawings.

Das Sensorsystem das diese Parkhilfe beinhaltet, besteht aus zwei optischen Sensoren 3 und 3′, welche korrosions- und schmutz­ geschützt in den Rückleuchten 3.4 des Kraftfahrzeuges unterge­ bracht werden können. Sie werden gepulst betrieben, und bestehen jeweils aus einem Strahlungssender 3.1 und einem Strahlungsem­ pfänger 3.2.The sensor system that includes this parking aid consists of two optical sensors 3 and 3 ', which can be protected against corrosion and dirt in the rear lights 3.4 of the motor vehicle. They are operated in pulsed mode and each consist of a radiation transmitter 3.1 and a radiation receiver 3.2 .

Die Sensoren sind in einem Winkel β zur Senkrechten ausgerich­ tet, um eine direkte Sonnen- oder Fremdlichteinstrahlung auf den Strahlungsempfänger zu verhindern. The sensors are aligned at an angle β to the vertical tet to direct sunlight or extraneous light on the To prevent radiation receivers.  

Strahlungssender und Strahlungsempfänger, welche parallel aus­ gerichtet sind, sind optisch voneinander isoliert, und in einem Abstand a zueinander angeordnet. Der Abstand a ist so zu wählen, daß eine gegenseitige Beeinflussung ausgeschlossen wird.Radiation transmitters and radiation receivers, which are made in parallel are optically isolated from each other, and in one Distance a arranged to each other. The distance a is to be chosen that mutual interference is excluded.

Die Strahlungssender werden mittels des Impulsgenerators 2, welcher durch das Schaltmittel 1 in Betrieb gesetzt wird, betrie­ ben. Das Schaltmittel 1 kann der Schalter für die Rückfahrleuch­ ten des Kraftfahrzeuges sein.The radiation transmitters are operated by means of the pulse generator 2 , which is activated by the switching means 1 . The switching means 1 can be the switch for the reversing lights of the motor vehicle.

Befindet sich nun ein Gegenstand oder ein Fahrzeugteil inner­ halb der Strahlungskeule 3.3 eines Strahlungssenders, so werden die daran reflektierten Impulsstrahlungsanteile vom jeweiligen Strahlungsempfänger erfaßt, und einer Signalaufbereitung 4 bzw. 4′ zugeführt.If there is now an object or a vehicle part within the radiation lobe 3.3 of a radiation transmitter, the pulse radiation components reflected thereon are detected by the respective radiation receiver, and fed to a signal processing 4 or 4 '.

Die Signalaufbereitung ist so ausgebildet, daß nur diejenigen höherfrequenten Signalanteile verstärkt und der Signalauswertung 5 zugeführt werden, die dem Frequenzspektrum des vom Strahlungs­ sender abgegebenen Signal es entsprechen.The signal processing is designed so that only those higher-frequency signal components are amplified and fed to the signal evaluation 5 which correspond to the frequency spectrum of the signal emitted by the radiation transmitter.

Die Signalauswertung erzeugt aus den eingehenden Impulsen, un­ ter Berücksichtigung einer Schaltschwelle, eine Steuerspannung. Mit dieser Steuerspannung wird über den Leistungsschalter 6 eine Warneinrichtung 7 in Betrieb gesetzt.The signal evaluation generates a control voltage from the incoming pulses, taking into account a switching threshold. With this control voltage, a warning device 7 is put into operation via the circuit breaker 6 .

Die Warneinrichtung 7 kann eine optische Warneinrichtung in Form einer Signalleuchte sein, die sich im Blickfeld des, beim rückwärts Einparken nach hinten blickenden, Fahrers befindet. Sie ist zweckmäßigerweise oberhalb des Heckfensters in einer eventuell sich dort befindenden Fondbeleuchtung installiert.The warning device 7 can be an optical warning device in the form of a signal light which is in the field of vision of the driver who is looking backwards when parking in reverse. It is expediently installed above the rear window in any rear lighting that may be located there.

Die hier für den Heckbereich eines Kraftfahrzeuges beschrie­ bene Parkhilfe in Form einer Abstandswarneinrichtung, kann ana­ log auch für den Frontbereich eines Kraftfahrzeuges verwendet werden.Described here for the rear of a motor vehicle bene parking aid in the form of a distance warning device, can ana log also used for the front area of a motor vehicle will.
