  • the warning signal is much louder than the engine noise and is perceived by the at least one person 13 due to the nature of the noise also conscious. If the distance between the motor vehicle 2 and the at least one person 13 is greater again, the warning signal automatically switches back to the engine noise as the audio signal. In a further increase in the distance between the at least one person and the motor vehicle 2, so that the magnitude of the danger potential drops below the first size, the generator 5 is completely switched off, so that no longer a warning signal from the generator 2 for the at least one person 13 is generated as an audio signal. This will be the

  • the type of environment 16 of the motor vehicle 2 for determining the size of the hazard potential can also be taken into account. If the motor vehicle 2 is equipped with GPS, for example, and there is a building with a special danger situation, eg. As a school 18, a hospital 19 or a kindergarten 17, within the immediate vicinity 16 of the motor vehicle 2, the size of the hazard at an equal distance between the person 13 and the motor vehicle 2 is rated higher than if no such environment 16 near the motor vehicle 2 is located. In addition, the distance between the special environment 16 and the motor vehicle 2 can also be taken into account. The smaller the distance between the motor vehicle 2 and the special environment 16, the greater the additional size of the hazard potential, which is determined due to the presence of the special environment 16 of the motor vehicle 2 and vice versa.
  • the volume of the audio signal is adapted to the risk potential of the motor vehicle 2 for the person 13, so that a particularly effective and safe acoustic warning of the person 13 in front of the motor vehicle 2 is possible. Furthermore, the audio signal is generated only when there is a danger to the person 13, so that the electric vehicle 3 or the hybrid vehicle 4 can move with no or only a small risk potential particularly quiet and therefore environmentally friendly.
