Abstract

The technology is characterized by the fact that it significantly increases road safety by detecting signals from emergency vehicles (fire brigade, ambulances, police, etc.) on the road and by using the multimedia device (radio, sound system, navigation system etc .) warns / draws attention.

Description

Initial situation:

Always "soundproof" vehicles and better multimedia technology, as well as sound systems in the vehicles prevent that one can recognize early oncoming emergency vehicles (fire brigade, ambulance, police, etc.) early and respond to the requirements of the Highway Code.

If emergency vehicles noticed too late, one often comes in a situation that may no longer allow the way to clear and / or form an alley for the rescue services.

Every second counts during mission drives and it is often about life and death.

This is where my idea comes in, which can be implemented for new vehicles as well as for the vehicle fleet without much effort:

function Description

• 1) External noise is detected via one or more microphones on the outside of the vehicle (usefully integrated into the foot of the roof antenna).
• 2) A detector electronics evaluates the noise and gives out a signal when regular sound sequences of a Einsatzhornes (fire, ambulance, police, etc.) are detected. The electronics can be adjusted to the different country-specific signal horns or should master all these different tone sequences. Ad-on: Because in some countries the traffic lights around the emergency vehicle are switched to red during the mission by radio, the monitoring of these radio signals would be an additional extension and improvement that could be incorporated.

Special feature of the system when used in new vehicles:

• 3) The detector electronics are integrated as software in the already existing multimedia technology of the vehicle without much extra effort.
• 4) The output signal of the detector electronics (from point 2) causes the multimedia device (radio, sound system, navigation system, etc.) to be muted and, if necessary, additionally on the multimedia screen, depending on the vehicle equipment, or in the onboard instrument panel Warning message "Attention emergency vehicle is approaching" appears.

Special feature of the system when used in existing vehicles

• 3) The detector electronics are retrofitted as an autonomous unit (small black box) in the existing vehicle.
• 4) The output signal of the detector electronics (from point 2) causes the existing multimedia device (radios, sound system, navigation etc.) to be muted. This can be done either directly over the most common "mute input" or via an additional box, which is ground into the speaker lines and thus gently interrupts or dampens the flow of current to the speakers.

Claims (2)

The technology is characterized by the fact that it significantly increases road safety by detecting signals from emergency vehicles (fire brigade, ambulances, police, etc.) on the road and by using the multimedia device (radio, sound system, navigation system etc .) warns / draws attention. The technology can be easily and inexpensively integrated into multimedia systems of new vehicles, as well as relatively inexpensive retrofitted into existing vehicles as a small black box.
