Abstract

Sensors which operate with ultrasonic sound scan the area behind the vehicle for obstacles. As soon as an obstacle is detected at a distance of 2 m# from the sensor, an audible signal inside the vehicle is triggered and at the same time a visual signal lights up on the dashboard. As the distance is reduced the sound and flashing frequency change until at a distance of 60 cm a warning sound is triggered and a warning flashing light with the sign "distance" lights up.

Description

Beschreibungdescription

Elektronisches KFZ-Abstandmessgerät Zur Verwendung von PKW, LKW und anderer Motorfahrzeuge ut Ultraschall arbeitender Sensoren tasten das Umfeld nach hinten nach Hindernissen ab.Electronic vehicle distance measuring device For use in cars, trucks and Other motor vehicles using ultrasonic sensors scan the environment towards obstacles.

Sobald ein Hindernis vom Abtastbereich erfasst wird, ertönt/erscheint ein akkustisches und optisches Signal.As soon as an obstacle is detected in the scanning area, sounds / appears an acoustic and optical signal.

An der Rückseite der Fahrzeuges angebrachte Sensoren tasten nach Einschalten des rückwärtsganges das hinter dem Fahrzeug befindliche Gelände (Umgebung) mit einem Radius von 2 m oder mehr nach Hindernissen ab.Sensors attached to the rear of the vehicle touch after switching on reverse the terrain (surroundings) behind the vehicle with a Radius of 2 m or more after obstacles.

Sobald ein Hindernis von diesem Äbtastfeid erfasst wird, ertönt im Inneren des Fahrzeuges ein akkustisches Signal, das bei verringernder Distanz sich verandert bis zu einem Warnton, wenn der Abstand weniger wie 60 cm beträgt.As soon as an obstacle is detected by this Äbtastfeid, sounds in the Inside the vehicle an acoustic signal that increases as the distance decreases changes to a warning sound when the distance is less than 60 cm.

Mit einem optischen Ent fernungsanzelger gekoppelt leuchtet einer Warnblinklampe mit der Aufschrift "Abstand" auf, wenn der obengenannter Abstand unterschritten wird.Coupled with an optical distance indicator, one lights up Hazard warning light labeled "Distance" when the above distance is fallen below.
