Technical Field

The invention relates to a motor vehicle for acoustically indicating a driving direction.

Background

In road traffic, it is increasingly difficult for, for example, pedestrians or cyclists to recognize such vehicles in everyday road traffic, since vehicles such as electric cars are becoming quieter.

In order to avoid dangerous situations, for example when a motor vehicle turns to the right in a right-hand traffic, optical blinkers are usually provided, which are not perceived by the blind.

This task is solved by: the motor vehicle comprises the following features:

-a first and a second vehicle lamp, wherein the first vehicle lamp comprises at least one first speaker unit and the second vehicle lamp comprises at least one second speaker unit for outputting sound signals, wherein the speaker units are integrated in the respective vehicle lamp;

at least one control device which is electrically connected to the loudspeaker units, wherein the control device comprises a memory in which at least one sound signal and a sequence for outputting the at least one sound signal are stored, and wherein the control device is set up to receive control data and to control the loudspeaker units in accordance with the control data with at least one of the sequences,

Detailed Description

Fig. 1 shows an exemplary motor vehicle 10 for audible driving direction indication, comprising a first and a second lamp 100, 200, wherein the first lamp 100 comprises a first loudspeaker unit 110 and the second lamp 200 comprises at least one second loudspeaker unit 200 for outputting an acoustic signal, wherein the loudspeaker units 110, 210 are integrated in the respective lamps. In the example shown, the first and second lamps 100, 200 are each designed as headlights of a motor vehicle 10.

The motor vehicle 10 further comprises a control device which is electrically connected to the loudspeaker units 110, 210, wherein the control device comprises a memory in which at least one sound signal and a sequence for outputting the at least one sound signal are stored, and wherein the control device is designed to receive operating data and to operate the loudspeaker units 110, 210 in accordance with the operating data using at least one of the sequences, wherein a first sequence 410 and a second sequence 420 are stored in the control device.

The course of the first sequence 410 is shown in fig. 1, wherein a corresponding diagram is shown in fig. 1A, which again illustrates the course of the first sequence 410 over time.

The control means during the first sequence 410 manipulates the loudspeaker units 110, 210 such that: to output this sound signal, the first loudspeaker unit 110 reduces the sound volume starting from a specifiable first start sound volume ST1 for a first period of time to a specifiable first final sound volume E1, the second loudspeaker unit 210 increases the sound volume starting from a specifiable second start sound volume ST2 for a second period of time to a specifiable second final sound volume E2, the first period of time and the second period of time overlapping during the first sequence 410.

The conical section in front of the motor vehicle 10 should clarify the path of the sound signal from the first loudspeaker unit 110 to the second loudspeaker unit 210, wherein the conical section pointing towards the middle of the two vehicle lights should indicate that the two loudspeaker units have approximately the same sound volume at this point in time. Due to the constantly changing volume from one loudspeaker unit to another, the sound signal drifts to a certain extent for a listener outside the motor vehicle, for example.

In the example in fig. 1 in which the first sequence occurs, since the sound signal drifts from right to left for the listener — viewed from the top illustration in fig. 1 and characterized by an arrow, it is indicated that the motor vehicle 10 will come to turn left.

During the second sequence 420 represented in the exemplary motor vehicle in fig. 2 or in the associated diagram in fig. 2A, the control device actuates the loudspeaker units 110, 210 in such a way that: to output this sound signal, the second loudspeaker unit 210 reduces the sound volume starting from the specifiable first start sound volume ST1 for a first period of time to a specifiable first final sound volume E1, the first loudspeaker unit 110 increasing the sound volume starting from the specifiable second start sound volume ST2 for a second period of time to a specifiable second final sound volume E2, the first period of time and the second period of time overlapping during the first sequence.

In the example in fig. 2 in which the second sequence occurs, it is indicated that the motor vehicle 10 will turn to the right, since the sound signal drifts from left to right for the listener, viewed from the upper diagram in fig. 2 and characterized by an arrow.

As shown in the graph with respect to the first sequence in fig. 1A and the graph with respect to the second sequence in fig. 2A, the first start volume ST1 is equal to the second final volume E2 and the second start volume ST2 is equal to the first final volume E1, wherein the second start volume ST2 and the first final volume E1 correspond to the volumes being zero. Further, the first and second start volumes ST1, ST2 start at the same point in time, wherein the first final volume E1 and the second final volume E2 are reached at the same time.

Fig. 3 shows a further example of a motor vehicle 10, which is similar to the example in fig. 1, wherein the first lamp 100 is designed as a headlight and the second lamp 200 is designed as a tail light of the motor vehicle 10.

In the example in fig. 1, the respective vehicle lamp 100, 200 or the associated loudspeaker unit 110, 210 is actuated by the control device using a first sequence 410, which is again illustrated in fig. 3A.

Fig. 4 shows a further motor vehicle 10, which is similar to the example in fig. 1 and 3, wherein the motor vehicle 10 comprises a third vehicle lamp, which in the example shown is designed as a rear light with an integrated third loudspeaker unit 310, wherein the first and second vehicle lamps 100, 200 are designed as headlights. The third vehicle lamp 300 includes a third speaker unit 310 for outputting a sound signal, wherein the third speaker unit 310 is integrated in the third vehicle lamp 300.

In the example in fig. 4, a third sequence 430 and a fourth sequence are also stored, wherein the control device during the third sequence 430 manipulates the loudspeaker units 110, 210, 310 such that: to output this sound signal, the first loudspeaker unit 110 reduces the sound volume starting from a specifiable first start sound volume ST1 for a first period of time to a specifiable first final sound volume E1, the second loudspeaker unit 210 increases the sound volume starting from a specifiable second start sound volume ST2 for a second period of time to a specifiable first intermediate sound volume ZW1 and reduces the sound volume starting immediately after reaching the first intermediate sound volume ZW1 for a third period of time to a specifiable second final sound volume E2, and the third loudspeaker unit 310 increases the sound volume starting from a specifiable third start sound volume ST3 for a fourth period of time to a specifiable third final sound volume E3 when the second loudspeaker unit 210 reaches the first intermediate sound volume ZW 1.

During the fourth sequence, the control means operates the loudspeaker units 110, 210, 310 in the reverse order to the third sequence 430.

As shown in the graph regarding the third sequence in fig. 4A, the first start volume ST1 is equal to the first intermediate volume ZW1 and the third final volume E3, wherein the second start volume ST2 is equal to the first and second final volumes E1, E2 and the third start volume ST3, wherein the second start volume ST2, the first and second final volumes E1, E2 and the third start volume ST3 correspond to the volumes being zero. Further, the first and second start volumes ST1, ST2 start at the same point in time, wherein the first final volume E1 is reached at the same point in time as the first intermediate volume ZW 1. Further, the third final volume E3 is reached at the same time point as the second final volume E2.
