Description

The invention relates to a marten repellent device according to the preamble of the claim.

Electronic or electrically operated marten repellent devices in motor vehicles should only be switched on when the vehicle is parked.

The marten repellent device should be switched on and off automatically.

Automatic marten repellent devices have been switched off in parked vehicles, among other things, by assigning a vibration sensor to the marten repellent device, which switches the marten repellent device off when the motor vehicle is vibrating, see for example DE 20 2010 009 217 U1 , and the marten repellent device switches on if there is no vibration.

Such a system often works very unreliably, since in vibration-reducing motor vehicles the vibration sensor may not respond to such weak vibrations, so that the marten defense device is switched on while driving.

If the vibration sensor is highly sensitive, it also reacts to vibrations from road traffic. For example, Vibrations caused by heavy trucks passing by are detected by the vibration sensor, so that the marten repellent device is switched off even when the motor vehicle is parked.

In the DE 20 2010 009 534 U1 An operating voltage-dependent activation of electrical or electronic marten repellent devices is described, the marten repellent device being switched on only when the voltage of the energy store, in particular the motor vehicle battery, drops as a result of the charging process being interrupted when the motor vehicle is parked, and is then switched off again when the battery voltage as a result of the driving situation taking place motor vehicle increases again.

The invention has for its object to design a marten repellent device for motor vehicles in such a way that the marten repellent is only switched on when the vehicle is parked. This activation should take place automatically.

To solve this problem, the marten repellent device according to the invention for motor vehicles is included

• a voltage measuring device which can be connected to an electrical energy storage device for measuring the voltage of an electrical energy storage device,
• evaluation electronics, preferably integrated in the voltage measuring device,
• a high voltage and / or an ultrasonic tone generator,
• - At least one high-voltage touch contact connected to the high-voltage generator and / or
• a loudspeaker unit connected to the ultrasound generator,

characterized by a

• - to the voltage measuring device and
• - timer (timer) connected to the high-voltage and / or ultrasonic generator,
  • - In which an adjustable interval time can be stored and
  • - Responds to voltage changes in the energy storage device detected by the voltage measuring device, and
  • - the marten repellent device switches on if no change in voltage is detected during the interval, and
  • - The marten defense device switches off if a voltage change is detected by the tension measuring device during the interval time.

According to the invention, the voltage on the motor vehicle battery is thus monitored to determine whether it is subject to changes in voltage.

In a moving motor vehicle, the battery voltage changes constantly or in very short time intervals because any electronics or consumers in the motor vehicle are in operation and are supplied with current. This results in a constant change in the battery voltage. When the motor vehicle is parked, there is no change in the battery voltage.

The marten repellent device according to the invention is switched on if there is no voltage change within the interval time, and it is switched off again when a voltage change is detected.

Modern motor vehicles have alternators that only switch on when needed. It can therefore happen that an alternator switches off while the motor vehicle is driving with a full energy store, so that the marten repellent device is switched on because it is wrong it is conveyed that the motor vehicle is parked. The same applies to electric cars, which in addition to the motor vehicle traction battery usually also have a 12V car battery for auxiliary units, which is also charged independently of the driving of the motor vehicle.

The invention is described below with reference to the accompanying figure.
