Definitions
- the invention relates to an emergency signaling device in a motor vehicle for manual and / or automatic notification of an emergency to a message center according to the
- An emergency reporting device must be installed as of 31.3.2018 obligatory in all new vehicles. It should serve to automatically or even by means of a simple actuator in the vehicle interior emergency call to a rescue or
- Such an emergency situation can be, for example, a traffic accident or a critical one
- Central component of such an emergency signaling device are in addition to necessary electrical storage and processing units for processing an "emergency strategy" and GPS devices for locating the motor vehicle, at least one microphone and at least one speaker, thereby free speech and hearing of or
- this document proposes the microphone with a cardioid characteristic, ie with a first range of higher or highest and a second range of lower or lowest input sensitivity
- the loudspeaker is arranged separately from the microphone in such a plane which faces the second, less sensitive area of the microphone.
- a microphone consisting of several microphones.
- Operating device is arranged. Furthermore, an evaluation unit for the preparation of Speech signals available, which can make a direction-selective evaluation of microphone signals of the microphones.
- DE 10 2005 058 826 A1 discloses a loudspeaker system by means of which, with little space requirement, directional signal transmission onto the loudspeaker system is possible
- At least two film loudspeakers are proposed, which allow a directed to a person signal bundling and are located near the head of the person, for example, in a headrest.
- the present invention is based on the object to provide an emergency reporting device in a motor vehicle, with the simple way good acoustic
- the invention is based on an emergency reporting device in a motor vehicle for the manual and / or automatic notification of an emergency to a reporting center.
- a free-hand communication device consisting of at least one microphone and at least one loudspeaker can be used.
- the microphone is arranged in a first, perpendicular to a longitudinal direction of the motor vehicle extending vertical plane and the speaker separated from the microphone in a second, perpendicular to the longitudinal direction of the motor vehicle extending, vertical plane.
- the microphone and the loudspeaker are additionally arranged in a middle region of the motor vehicle contained in a vertical longitudinal center plane.
- the first plane seen in an ordinary direction of travel of the motor vehicle, is located behind the second plane and the second plane, as seen in the direction of travel, is located in an area from the head of a vehicle
- Vehicle driver is arranged.
- the second plane viewed in the longitudinal direction of the motor vehicle, is arranged in the region of an A pillar (if present).
- the area of an A-pillar also includes a certain distance to both sides of the A-pillar, which according to the experience of the Applicant can be quite several centimeters each.
- This positioning ensures a sufficiently close distance to both the driver and the rear passenger.
- said second level will thus lie approximately within such an area, which, viewed in the direction of travel, begins approximately at the driver's forehead and extends to behind the driver, between this and the rear passenger.
- the said, second plane - viewed against the direction of travel - arranged in the rear region of the A-pillar. This causes that already at low
- the headliner for the loudspeaker is also to be assessed as a crash-proof area in vehicles with a low deformation potential.
- the microphone has a directed onto the driver and a passenger directivity.
- the microphone and the speaker are arranged within the central area on the vertical longitudinal center plane of the motor vehicle.
- Doubletalk operation is understood to mean such an operation in which the voice of a call partner of the message center is audible via the loudspeaker and the microphone is sounded both by the language of the call partner and by the language of the occupant or occupants.
- the computational effort for the downstream in the signal processing EchoCancelation filter is easier to design, since with less feedback from the speaker into the microphone is to be expected.
- the microphone has a cardioid characteristic, wherein two speakers are present, which are connected as a dipole. This is done in such a way that a sound pressure level of the loudspeakers in the direction of the microphone is very low or minimal. This also allows an undesirably strong sound of the microphone through the speaker in the so-called Doubletalking operation even more effectively avoid.
- FIG. 1 is a side view of a motor vehicle in an embodiment of the
- Fig. 3 is a greatly simplified representation of the arrangement of speakers
- Fig. 4 is a greatly simplified representation of the arrangement of speakers
- Fig. 5 shows another motor vehicle with a further embodiment of the
- a motor vehicle K can be seen, with 1 being a windshield, 2 an interior mirror, 3 a microphone and 4 a headliner are quantified.
- a driver P1 and a passenger P2 have seated on front seats 7 and a rear passenger P3 on a rear bench 8 directly behind the driver P1.
- Both the driver P1, the passenger P2 and the rear passenger P3 have assumed an ordinary sitting position, that is, they touch at least approximately with their backs a seat back 7a and a backrest 8a. They are of average size.
- the motor vehicle K is equipped with an emergency signaling device which can be actuated manually or automatically in the event of an emergency.
- the microphone 3 and the speaker 6 are to allow in the event of an emergency free speech and hearing of a vehicle occupant, such as the driver P1.
- the microphone 3 is mounted on the interior mirror 2. Deviating from this, an installation of the microphone is also in the region of the headliner 4, preferably in the region of the transition between windshield 1 and headliner 4, conceivable. There it may, for example, also be accommodated in a lighting module (not shown).
- the loudspeaker 6 is installed in an area from the head K1 of the vehicle driver P1 and also from the head K2 of the passenger, in particular in a lighting module 5 which is located in the headliner 4 or is arranged thereon.
- the radiates are located in the headliner 4 or is arranged thereon.
- Speaker 6 down in the direction of the vehicle floor, that is orthogonal to a longitudinal direction L.
- the microphone 3 is thus arranged in a first plane E1.
- the plane E1 represents a vertical cross-sectional plane through the motor vehicle K, which is perpendicular to the longitudinal direction L or to an ordinary direction of travel F of
- Motor vehicle K is aligned and in front of the driver P1 or before the
- Passenger P2 is located.
- the loudspeaker 6 is arranged offset to the plane E1 at a distance a1 in a second plane E2, which runs parallel to the plane E1. Seen in the direction of travel F, ie from the direction of one standing at the rear of the motor vehicle K.
- the plane E2 can be such that it is in the selected one
- the microphone 3, which is arranged in the first plane E1, has a pronounced directional characteristic.
- the microphone 3 has a both on the
- the microphone 3 can preferably also be formed from a microphone array, which consists of a plurality of microphones. For example, one out of three microphones existing microphone array conceivable, the microphones are arranged like a triangle, with pointing in the direction F or counter to the direction of travel F "triangle tip" (not shown).
- the plane E2 on which the downwardly directed speaker 6 is located is now arranged in a region from the head K1 of the driver P1 or from the head K2 of the passenger P2.
- the term area of an A-pillar should be understood to mean such a region B2, which also includes distances a2 and a3 on both sides of the A-pillar 10 in the longitudinal direction L of the motor vehicle K, which can each amount to several centimeters and be practicable and attainable the desired acoustic properties are still considered useful.
- As a value for the distances a2 and a3, a range of about 10 to 20 cm is considered quite possible.
- the plane E 2 viewed counter to the direction of travel F, is arranged in a rear region 100 of the A-pillar 10.
- the rear area 100 extending from the center of the A-pillar 10 also includes the distance a3.
- the plane E2 is thus located between the head K1 of the driver P1 and a head K3 of the rear passenger P3 (see also Fig. 1 and 2).
- both the microphone 3 and the loudspeaker 6 are arranged in a central region B 1 which contains a vertical longitudinal center plane E 3 of the motor vehicle K.
- both the microphone 3 and the speaker 6 are located on this longitudinal center plane E3.
- Speaker 6 delivered sound pressure level dB except for the heads K1 and K2 from the driver P1 and passenger P2 at the microphone 3 falls primarily to the area II lower or lowest input sensitivity.
- the speaker 6 is
- Cardioid characteristic N is used. This characteristic therefore offers no special
- the region I faces the second plane E2.
- two conventional speakers 6a and 6b are arranged. Specifically, the speakers 6a, 6b are connected as a so-called dipole. This is done in such a way that a sound pressure level dB3 of the loudspeakers 6a, 6b in the direction of the microphone 3 'is very low or minimal. In the direction of the head K1 of the driver P1 and the head K2 of the passenger P2 facing sound pressure level dB1 and dB2 are significantly higher.
- the plane E2 is disposed in the rear portion 100 of the A-pillar 10 and is located between the head K1 of the driver P1 and the head K3 of the rear passenger P3.
- the microphone 3 ' is located within the area B1, preferably on the longitudinal center plane E3.
- the speakers 6a, 6b are also in this case preferably oriented down to the vehicle floor and preferably arranged centrally to the longitudinal center plane E3.
- FIG. 5 shows a motor vehicle K 'with an emergency signaling device consisting of a microphone 3 and a loudspeaker 6, in which the plane E2 coincides with a partition 9 located behind the driver P1 and the passenger P2.
- the speaker 6 is thus mounted on or in the partition 9.
- the motor vehicle K ' is a commercial vehicle, wherein a passenger compartment 11 is separated from the rear space 12 designed as a load compartment by the partition wall 9.
- the motor vehicle K 'can also be a sports car with only two seats, the partition 9 corresponds to a rear wall and a separation between a
