Abstract

Electronic marten defense in a housing, mountable in the engine compartment of a motor vehicle, characterized in that it contains the following defense measures: • Ultrasound with high sound pressure> 100 dB and random frequencies in the range 20 to 50 kHz. Light through bright LEDs with random frequency and amplitude variance or special patterns such as fire simulation or strobe effects. various random tones and noises (knocking, knocking, engine noise, noise from enemies such as dog, cat, fox, badger) • Flashes of light by bright LEDs combined with thunder (thunderstorm simulation) • Vibration or shaking by a vibration motor with a random vibration frequency

Description

Current status

A marten protection for motor vehicles serves to protect against bite damage in the engine compartment. Currently installable martens are available that work with the following defense techniques, either individually or in combination:

• Ultrasound

Ultrasound is a very simple method. It works with a very high sound pressure> 100 dB. Due to the high frequency of over 20 kHz, this sound is inaudible to humans. Simple devices work with a single sine wave that is turned on for a few seconds and then turned off for several seconds. The effectiveness of ultrasound to ward off martens is partly confirmed and sometimes doubted. According to the ADAC researchers are of the opinion that ultrasound is not a suitable means for marten defense. In addition, there is always the problem with ultrasound that can only be checked with special measuring technology if any sound is emitted and thus the marten defense works technically.

• high voltage

High voltage is good protection but requires knowledge and a lot of installation time. There is also a risk for people who could unknowingly touch the loaded plates.

• light

There are some solutions that work with light. Partially with simple flashing or stroboscopic effects. This process is still relatively new and the effect could not be verified by research. It is just as easy to install as an ultrasound device.

All these measures have either the disadvantage that they are not effective as a single solution or the cost of installation is high.

Troubleshooting

• • voll automatischer Betrieb, also Erkennung ob Pkw abgestellt ist oder sich noch in Fahrt befindet durch Bewegungserkennung und Batteriespannungsüberwachung
• • einfache Montage, Befestigung im Motorraum und Anbringen der Stromversorgung
• • 5 verschiedene Abwehrmechanismen, durch die hohe Anzahl der Abwehrmaßnahmen besteht erhöhter Schutz vor Marder
• • Abwehrmechanismen zufällig in Intensität und Muster, dadurch ist die Gewöhnung des Marders gering
• • Mechanismen zeitlich zufällig hintereinander oder kombiniert zeitgleich
• • Überwachung mit PIR-Sensor, dadurch Erkennung ob ein Marder in den Motorraum eingedrungen ist und Steuerung der Abwehrmaßnahmen und Schonung der Batterie und die Umwelt vor Lärm
• • sehr geringer Stromverbrauch im Überwachungszustand, dadurch Schonung der Batterie
• • Spannungsüberwachung, dadurch Schutz der Batterie vor Entladung durch Abschaltung des Marderschutzes

By combining five different defense mechanisms, the likelihood of the animal's flight is to be increased many times over. The installation should be limited to mounting a housing and attaching the power supply. The assembly takes place at a free suitable place in the engine compartment. The presented marten defense has the following functions:

• • fully automatic operation, ie detection of whether the car is parked or is still in motion through motion detection and battery voltage monitoring
• • easy installation, mounting in the engine compartment and mounting the power supply
• • 5 different defense mechanisms, due to the high number of defenses increased protection against marten
• • Defense mechanisms random in intensity and pattern, thus the habituation of the marten is low
• • Mechanisms randomly in time, or combined at the same time
• • Monitoring with PIR sensor, thereby detecting whether a marten has penetrated into the engine compartment and control of the defensive measures and protection of the battery and the environment from noise
• • very low power consumption in the monitored state, thus conserving the battery
• • Voltage monitoring, thereby protecting the battery from discharging by switching off the marten protection

The main advantage of this marten protection is the large number of defensive measures and as a result, the animal's urge to escape is much greater. Even if a single defensive measure is not effective, the 4 other measures can still be used to escape.

• • Ultraschall mit hohem Schalldruck und zufälligen Frequenzen im Bereich 20 bis 50 kHz
• • Licht durch helle LEDs mit zufälliger Frequenz- und Amplitudenvarianz (Simulation von vorbeifahrenden Autos, Simulation von Feuer, Stroboskopeffekte)
• • verschiedene zufällige Töne und Geräusche (Schlag, Klopfen, Donner, Motorgeräusch, Geräusche von Feinden wie Hund, Katze, Fuchs, Dachs)
• • Lichtblitze durch helle LEDs mit Donnerschlag kombiniert (Gewittersimulation)
• • Vibration oder Rütteln durch einen Vibrationsmotor mit zufälliger Frequenzvariation, diese Vibration überträgt sich über das Gehäuse auf den gesamten Motorraum

The 5 defense mechanisms are:

• • Ultrasound with high sound pressure and random frequencies in the range 20 to 50 kHz
• • Light through bright LEDs with random frequency and amplitude variance (simulation of passing cars, simulation of fire, stroboscopic effects)
• • various random sounds and noises (beat, knock, thunder, engine noise, sounds of enemies such as dog, cat, fox, badger)
• • Flashes of light combined with bright thunderbolts (thunderstorm simulation)
• • Vibration or shaking by a vibration motor with random frequency variation, this vibration is transmitted through the housing to the entire engine compartment

A PIR sensor detects the intrusion of the Marder and starts the defensive measures. All mechanisms are executed consecutively and / or simultaneously. The start time of a measure and the duration are random so that in no way can get used to the animal. A simultaneous monitoring by a PIR sensor can detect the flight of the animal and stop the defense after a short waiting time of about 30 seconds. This protects the battery of the vehicle and the environment.
