Definitions

  • the invention relates to a tunnel sensor for a motor vehicle.
  • tunnel is used not only to refer to tunnel tubes but to all types of built-up routes, including underground garages, car parks, car washes, etc.
  • the vehicle driver When approaching a tunnel, the vehicle driver has to perform a number of functions for reasons of driving comfort and safety, such as Closing vehicle openings such as windows or sunroofs, switching on headlights, switching the air conditioning system in recirculation mode, switching the audio system from radio reception to e.g. Play music stored on a sound carrier.
  • DE 197 48 454 AI discloses an optical tunnel sensor which automatically switches on the vehicle headlights when entering a tunnel.
  • a disadvantage of this tunnel sensor is that the sensor cannot be functional at night because entering the tunnel does not lead to any significant change in the ambient light.
  • the object of the invention is to provide a tunnel sensor which is independent of the ambient light.
  • Fig. 1 shows a first exemplary embodiment.
  • Fig. 2 shows a second exemplary embodiment
  • the block diagram in Fig. 1 shows a microphone 1, which is attached to the vehicle so that it the ambient noise of the vehicle, in particular the vehicle noise reflected from the environment or typical operating noise e.g. a car wash.
  • Comparison means 2 and storage means 3 are provided as evaluation means 11 for evaluating the ambient signal with regard to the presence of a typical ambient noise.
  • the signals from the microphone 1 and the storage means 3 are compared in the comparison means 2.
  • the storage means 3 is used to store a set of typical acoustic ambient noise patterns which are characteristic for driving through a tunnel.
  • a function memory 4 a function control unit 5 and vehicle control units 6-10 are provided.
  • vehicle control devices in the drawing window / sunroof control device 6, light control device 7, climate control device 8, audio control device 9, antenna drive control 10.
  • the microphone 1 continuously records the ambient noise and transmits a corresponding electrical ambient signal to the comparison means 2.
  • the comparison means 2 compare the noise recorded by the microphone with that in the Storage means 3 stored ambient noise patterns. As soon as the comparison means 2 recognize a significant similarity between the ambient noise and one of the stored noise patterns, the current functional states of the vehicle control devices 6-10 are read out and stored in the function memory 4.
  • the functional states read out can include: the volume setting or the transmitter classification of the audio system, the positions of the windows and the sunroof, the air conditioning setting, the headlight setting (on / off), the position of the retractable exterior mirrors, the position of a retractable antenna and other functions which are used during a Tunnel passage should be changed.
  • the function control unit 5 controls the vehicle control units 6-10 in accordance with a predetermined assignment with preprogrammed values.
  • the assignment can be programmed individually and based on the different stored noise patterns. It can be provided that when the recorded ambient noise is assigned to a passage through a car wash, the vehicle openings, that is to say windows and sunroof, are closed, the exterior mirrors are folded in and the antennas are retracted. If a passage through a tunnel tube is recognized, it can be provided that the vehicle openings are closed, the air conditioning system is switched from fresh air to recirculated air and the audio system is switched from radio reception to mute or a transmitter that can be received in the tunnel or the playing of a sound carrier. Furthermore, when driving through a tunnel pipe, the engine control unit could be activated and put into an operating mode in which the exhaust gas emissions are minimized.
  • a fine differentiation according to ambient noise is possible by using methods of pattern recognition e.g. using neural networks, which as such are prior art.
  • the comparison carried out in the comparison means 2 can be based on the fact that a sudden increase in the amplitude of certain frequencies of the ambient noise is detected.
  • FIG. 2 Such an exemplary embodiment is described in FIG. 2, in which components with the same effect are identified with the same position symbols.
  • a spectral analysis unit 12, 13 is provided as the evaluation means 11 ', which, when a characteristic spectral distribution is present, indicates that a tunnel has been traveled through. When a tunnel trip is detected, the measures described in connection with the exemplary embodiment according to FIG. 1 are taken.
  • the spectral analysis unit consists of one or more frequency filters 12, which can be designed as low-pass, band-pass or high-pass filters, and a downstream amplitude evaluation unit 13.
  • the amplitude evaluation unit 13 is a combination of time profiles of filter output signal patterns typical of tunnel passages. Detects intensities, the current functional states of the vehicle control units 6-10 are read out and stored in the function memory 4. The further procedure is analogous to that of the exemplary embodiment in FIG. 1.

Abstract

La présente invention concerne un détecteur de tunnel pour automobile, conçu pour commuter automatiquement des fonctions (6-10) du véhicule. Ce détecteur comprend au moins un microphone (1), installé à l'extérieur du véhicule et permettant de produire un signal électrique de l'environnement qui reproduit le bruit d'environnement courant du véhicule. Selon cette invention, des systèmes d'analyse (11) permettent d'analyser le signal d'environnement par rapport à la présence d'un bruit d'environnement typique, caractéristique du passage dans un tunnel. Si le modèle de bruit typique du passage dans le tunnel est présent, une séquence associée de fonctions (6-10) du véhicule est commutée.
