Abstract

Disclosed is a vehicle having a plurality of speakers through which a virtual sound source can be formed to direct a driver in a particular direction for his attention.

Description

The invention relates to a vehicle according to the preamble of claim 1. Furthermore, the invention relates to a method for a vehicle.

In traffic, when using a non-autonomous (or even in a level 0 to 4 autonomous vehicle) vehicle or automobile, traffic situations or hazardous situations occur in which immediate intervention by the driver is necessary. An intervention requires the driver, for example, a brake, dodge or accelerate. In such situations it is essential and important that a reaction time of the driver is as short as possible. It is also important that the driver adapts to the traffic situation and acts consistently.

Furthermore, nonautonomous or semi-autonomous vehicles are known from the prior art which assist a driver in explosive traffic and dangerous situations. In this case, for example, a visual or audible signal for the driver is issued to prompt this to a reaction. As an optical signal or request, it is known, for example, that a flashing display is executed in a display, wherein the display can be arranged, for example, in the tachometer console. The display is, for example, an adaptive cruise control (ACC) brake request. It is also known, in addition to illuminate hazardous situations by, for example, game or pedestrians are illuminated on the roadside by the vehicle. As acoustic signals or prompts, "beep" or "gong" signals are used to animate the driver to a quick action. A disadvantage of the optical signals in the form of additional lighting of dangerous situations on the road is that there is a possibility that the driver does not notice them, for example, if he has turned his eyes away from the road or is otherwise distracted. A disadvantage of the optical signals on the display, in turn, that the driver must turn his eyes away from the road to perceive the flashing display on the display. To see the display on the display, it is further required that the driver's eyes must adjust to the display by focusing. As a result, valuable reaction time passes disadvantageously. The disadvantage of the acoustic signals is that they are not intuitive and the driver often does not know how to react, because it is not clear what the potential danger might be. If a flashing display is additionally provided in the display, he can direct his gaze to the explanatory display, which, however, again requires an unnecessarily long reaction time.

The object of the present invention is to provide a vehicle and a method, with each of which the safety for persons in the vehicle is increased.

This object with regard to the vehicle is achieved according to the features of claim 1 and with regard to the method according to the features of claim 15.

Particularly advantageous embodiments can be found in the dependent claims.

According to the invention, a vehicle is provided in which a plurality or plurality of loudspeakers are arranged at different positions. A sound for at least one person, in particular a driver, can then be generated within the vehicle via the loudspeakers. Advantageously, a control device is provided, via which the loudspeakers can be controlled. In this case, the activation can be carried out such that at least one virtual sound source can be formed at different positions. The virtual sound source can then form sound waves in the form of an acoustic sound and / or in the form of a language in such a way that the attention of the at least one person, in particular the driver, is directed in the direction of the virtual sound source.

This solution has the advantage that it is not easy, as in the prior art, an acoustic signal is output through the speakers, but that the acoustic signal comes from a virtual sound source that can be flexibly formed with respect to the at least one person. Thus, for example, the virtual sound source, for example, starting from the driver lie in the direction in which an object is provided, to which the driver is to be pointed, such as a game on the roadside. Thus, for reaction time reduction, the driver's attention can be instantaneously directed to any object, such as outside the vehicle, and an immediate change in the driver's line of sight in the desired direction can be forced. Thus, a vehicle is provided in which an acoustically locatable signal can be formed, which can be output from different positions forth, what as acoustic holography can be called. This is also extremely advantageous for a potential driver of a semi-autonomous vehicle who can then actively intervene if necessary.

It can be provided that the reference person for the virtual sound source, in particular before the start of the journey, is adjustable or definable.

In a further embodiment of the invention, the arrangement of the at least one virtual sound source takes place as a function of a dangerous situation or traffic situation to which the person, in particular the driver, should be informed. This is in particular a situation in the vehicle environment. Alternatively or additionally, the arrangement of the virtual sound source in dependence on an object in the vehicle environment to which the person, in particular the driver to be notified, take place.

Preferably, the virtual sound source is formed outside the vehicle, for example to alert a driver to dangerous situations and / or to objects outside the vehicle. The virtual sound source can thus be configured in such a way that the impression is created for the at least one person that the virtual sound source is a sound source which is designed in the area of the danger situation and / or in the area of an object to be displayed.

Advantageously, the arrangement of the virtual sound source via the control unit is such that a direction between the at least one person and the virtual sound source corresponds approximately to the direction between the at least one person and the object and / or the dangerous situation. As a result, a glance of the at least one person can be directed directly to the dangerous situation.

In the arrangement of the virtual sound source by the control unit, a changing relative position between the dangerous situation and the vehicle and / or between the object and the vehicle is preferably taken into account as a function of time. If, for example, the relative position between a dangerous situation and the vehicle changes, for example by the vehicle driving, the relative position of the at least one virtual sound source relative to the vehicle is correspondingly adjusted. For this purpose, it is advantageous if, in the arrangement of the virtual sound source, a speed and / or an acceleration and / or a direction of the vehicle is taken into account. The relative position between a dangerous situation and the vehicle can be determined, for example, by means of a Doppler effect or a Light Detection and Ranging (LiDAR).

Preferably, at least one sensor is provided to detect objects and / or dangerous situations. The sensor is preferably connected to the control unit. Preferably, the at least one sensor or a plurality of sensors detects dangerous situations and / or objects in an environment of at least one peripheral side or several peripheral sides or all peripheral sides of the vehicle. In addition, it is conceivable that the at least one sensor or a plurality of sensors detects the surroundings from an upwardly facing side or a plurality of upwardly directed sides, such as, for example, a roof side of the vehicle. By detecting the roof-side exterior space, for example, approaching drones or rescue helicopters can be located. In other words, the vehicle may be equipped with various detectors covering all sides of the vehicle as well as the vehicle roof. As sensor or as sensors, an optical sensor and / or or acoustic sensor and / or a thermal sensor can be provided, for example. Thermal sensors can be used, for example, in the case of dangers due to burning tires, forest fires, etc. The optical sensor or sensors are / are selected, for example, from the following types of sensors, wherein a combination is also possible: camera, light detection and ranging (LiDAR) sensor, radio detection and ranging (radar) sensor, infrared (IR) sensor , Ultraviolet (UV) sensor. As an acoustic sensor, for example, a microphone may be provided. The acoustic frequency range is intended to include both infrasound (below approximately 20 Hz), the low frequency range (below approximately 100 Hz), the human auditory hearing range (approximately 16 Hz to approximately 20 kHz) and the ultrasound range (greater than approximately 20 Hz). 18 kHz). Preferably, the sensors are arranged on the vehicle. However, it is also conceivable that, alternatively or additionally, the vehicle, in particular its control unit, is connected to an external sensor and / or can access it, for example to a sensor attached to a drone. Thus, for example, a traffic camera provided on a traffic surface may be arranged, which is then accessed by the vehicle in order to detect dangerous situations and / or objects. As an alternative or in addition to the sensor, it is also conceivable for the control unit to obtain information or location coordinates relating to dangerous situations and / or objects to which the driver is to be informed from the environment in any other way.

For example, it can be detected with the sensor in the form of a camera or vehicle camera that suddenly a child is running on the road. Subsequently, a virtual sound source can be generated from the direction of the child. Thus, the driver can perceive the sudden acoustic signal, automatically locate and direct his eyes and attention immediately on the dangerous situation. Thus, the driver can react as quickly as possible and appropriate to the situation. Furthermore, it is advantageous that an acoustically locatable signal can also be registered by the driver if he has not just directed his eyes to the road.

In a further embodiment of the invention can be provided that the object and / or the dangerous situation is also visually highlighted / are. In particular, it can be provided that the control unit controls at least one light source of the vehicle in such a way that the object and / or the dangerous situation can additionally be illuminated by it. In other words, in addition to the acoustic warning, a visual stimulus can also be set. Preferably, a light distribution in the detected hazardous situation is locally and / or temporally variable. In other words, for example, the danger situation can be visually highlighted by the light distribution in the angular range of the danger situation is locally and / or temporally changed. This is done, for example, by the fact that briefly more or less light can be provided in a certain angular range and / or that a flashing highlighting takes place.

For visual highlighting, the at least one light source can be designed as an adaptive driving beam (ADB). For example, a matrix module is suitable for this, in which a large number of individual light-emitting diodes (LEDs) can be controlled separately and thus switched on and off as well as dimmed. By a high number of pixels or a high number of LEDs then the detected by the sensor, such as a camera system, objects or dangerous situations can be illuminated separately, with which the at least one person, especially the driver, in addition to the virtual sound source can be made aware of it. Thus, for example, it is conceivable for the optical highlighting to access an already existing ADB of a vehicle. If the vehicle does not have a high-resolution ADB, it is preferably provided to use a further light module as the light source. This is designed in such a way that it can locally and / or temporally change the light distribution and / or a light color in order to mark the dangerous situation and / or the object. The light module has, for example, a pivotable or rotatable light beam which emits the light, for example, of one or more LEDs or laser diodes in a narrow angular range. In other words, an optical highlighting of the area, which requires increased attention, can be done additionally. Thus, the signals of the vehicle with multiple senses can be perceived simultaneously, resulting in a multimodal or cross-modal perception.

In a preferred embodiment, the control unit generates at least one virtual sound source with a wave field synthesis (WFS) which can be used to design and arrange virtual sound sources in a simple manner and extremely flexibly. Basis of the WFS is the huygenssche principle. An acoustic wave front of any sound sources can be generated by the superposition of acoustic elementary waves. By means of the control unit, the required time-dependent elementary waves can then be calculated from each loudspeaker. The controller will then actuate each loudspeaker diaphragm if and only if the wavefront of the desired virtual sound source were to reach the position of the loudspeaker. The wavefronts of all speakers interfere, creating a wavefront of the desired virtual sound source. When an external acoustic noise (such as another vehicle's bursting tire or a vehicle crash) is to be represented by the WFS, its sound waves interfere with the acoustic sound waves of the causative event. Here, the use of the WFS has the advantage of better understanding the danger object, i. angle accurate, can represent.

Alternatively or additionally, it can be provided that the control unit forms a Dolby Surround System with the loudspeakers in order to generate the at least one virtual sound source. In this case, the sound source can also be imitated in a certain direction. By the perception of time differences and level differences between the speakers, the at least one person, in particular the driver, receives through the system a spatial sound impression. As a result, the virtual sound sources are so-called phantom sound sources. Preferably, positioning and control of the loudspeakers is then adapted to the position of the person who is to be alerted, for example, to a dangerous situation, such as the driver. Thus, the positioning and control of the speakers, for example, be adapted to a driver's seat of the vehicle. As a result, the disadvantage can be eliminated that the phantom sound sources positioned by the level and transit time differences-in contrast to the virtual sound sources of the WFS-have no location stability. As a result, the phantom sound source is located at a different location for each person in the vehicle. The persons in the vehicle are, for example, a driver, co-driver and / or passengers in the backseat. In other words, it may be provided to tune the acoustic signals of the vehicle to direct the attention of the driver to the driver's position by the positioning and control of the speakers is also adapted to the driver's position.

In a preferred embodiment, the control device can the virtual sound source in a headset of the driver, and / or by, in particular micro, speakers in a pair of glasses, in particular in eyeglasses of glasses, and / or in a seat and / or in a headboard create recessed speakers. Of course, one or more persons, in particular the driver, wearing glasses, in particular a virtual reality glasses, which is then controlled by the controller for forming the virtual sound source.

Advantageously, the position of the ears of the person to be informed by sensor, in particular by camera, detectable in order to inform the person purposefully. Alternatively or additionally, it may be provided to detect the orientation of the head. For autonomous vehicles, the head position of the listener can be determined.

The loudspeakers are preferably arranged around a driver's seat in order to generate virtual sound sources at least for the driver. It is also conceivable that the speakers are simply arranged in a row or U-shaped. In a U-shape, two speaker legs may each be provided laterally of the driver and a connecting leg may be arranged in front of the driver. It would also be conceivable to provide the arrangement of the speaker arcuate. It is particularly advantageous if the loudspeakers together form a closed shape, such as, for example, an annular or circular or rectangular shape, since in a simple manner a virtual sound source can be formed from all sides of the at least one person, such as the driver. In other words, a closed or open loudspeaker band is realized. This preferably surrounds the driver's seat of the vehicle. To form a well localizable virtual sound source, a total number of speakers should be at least about 30, more preferably 100 to 300, more preferably 300 to 1000. The upper limit could also be a few thousand, depending on the technology available in the future.

The loudspeakers may preferably be controllable with the control unit such that a plurality of virtual sound sources can be used simultaneously at different positions. As a result, the driver can be made aware, for example, of several dangerous situations and / or objects.

The at least one virtual sound source is preferably embodied both between the at least one person, in particular between the driver and the loudspeakers, and also on the side or rear side of the loudspeaker facing away from the at least one person. In other words, the WFS can generate virtual sound sources behind the loudspeaker array, ie preferably outside the vehicle, as well as focused sound sources between the listener and the loudspeaker array, ie preferably within the vehicle, which can locate all vehicle occupants at the same and desired location.

In a further refinement of the invention, the noise and / or speech output by the at least one virtual sound source can be adapted to the object and / or to the dangerous situation. Thus, it is conceivable, for example, that in the case of a lorry (truck) that suddenly appears, a truck noise is formed by the virtual sound source from the direction of the emerging truck. Thus, there is generally the possibility that, in particular with the wave front synthesis, an acoustic signal is generated whose noise signature corresponds to the identified object to which the attention is to be directed.

The noise is preferably a signal sound or an acoustic signal. As a signal sound is conceivable to provide a warning sound, which is in particular locatable by the at least one person and thus is formed from the appropriate direction. Thus, a simple sound may be provided to direct the driver's attention in a particular direction. Furthermore, it is conceivable to provide a warning signal as signal sound. If the vehicle has acoustic sensors, it is conceivable as a signal sound also passer out calls, such as cries for help, or a siren, such as a siren, or similar important acoustic sounds from the environment to detect and, in particular with the WFS, from the right one Direction in the vehicle play and / or amplify. Thus, it is conceivable that the noise or speech is amplified from the environment to which or to which reference should be made.

Furthermore, it is conceivable to provide as signal sound, for example, a beep signal or a gong signal.

In a further embodiment of the invention can be provided to issue as a noise in addition a keynote. This is preferably real, in particular localizable, ambient noise outside the vehicle. Thus, real ambient sounds, for example, can be played back for entertainment purposes. Alternatively or additionally, it is also conceivable to provide artificial ambient noise, such as, for example, sea noise or birdsong.

In a preferred embodiment, as already explained above, noise may be provided as an orientation sound, such as a truck noise.

In a further embodiment of the invention, the output speech may be a, in particular locatable, navigation hint, with which the virtual sound source can be used for information purposes. For this purpose, it is alternatively or additionally conceivable that, for example, traffic signs or traffic signs are read from the correspondingly appropriate direction. Alternatively or additionally, it is also conceivable that the object designation is output as language. For example, in the case of the truck object, the word "truck" or, in the case of the pothole object, the words "watch pothole" may be read out.

In a preferred embodiment, as noted above, the noise or speech may be adapted to the object and / or the hazardous situation to be pointed to. In this case, a suitable adaptation of the noise or the language takes place. In particular, the noise or the language is designed in such a way that it can be recognized by the at least one person which object is involved. Alternatively or additionally, it can be provided that the noise or the speech is configured in such a way that the at least one person can see how large the distance to the object is, for example by adjusting the volume of the noise or speech accordingly. In other words, if, for example, another road user in the vicinity is identified via the at least one sensor, this can be assigned a suitable acoustic sound or a suitable language. In this case, it may be suitable that the at least one person, in particular the driver, can recognize the acoustic noise or the language where the other road user is, what the road user is and possibly how close the other road user is. For example, different frequency patterns for different road users can be used to identify the road user. The proximity of the road user can be recognized by different frequencies, the volume or repetition rates of the sound and / or the language. In a further embodiment, external ultrasound sources can be output by means of transformation, in particular by means of measurement and computer-aided transformation to lower frequency values, by means of WFS as acoustic waves. Similarly, infrasound can be reproduced by higher frequencies.

The above-mentioned hazardous situations may be one or more of the following situations: objects on a carriageway, pothole, in particular deep pothole, accident site, breakdown of another vehicle in the immediate vicinity, risk of collision with other road users, other road users in the blind spot, Road ice icing (black ice), aquaplaning danger from puddles on the road, approaching drone.

An object can be a road user. For example, a road user is a vehicle that does not have one or more people, such as an autonomous vehicle, and / or a pedestrian and / or an animal. The object may also be an object, such as a traffic sign. The vehicle may be an aircraft or a waterborne vehicle or a land vehicle. The land-based vehicle may be a motor vehicle - in particular a truck or a passenger car or a motorcycle - or a rail vehicle or a bicycle.

In a further embodiment of the invention can be provided that the vehicle has at least one device and / or is connectable to at least one device. An image signal and / or a haptic signal can be output via the device in addition to the noise and / or speech that is / are output via the at least one virtual sound source. The device may be, for example, a display. The display is again, for example, a vehicle display or a smartphone display or an augmented reality glasses or any other display within the vehicle. Furthermore, it is conceivable as a device, a vibration unit provided, which is provided for example in a bracelet of at least one person or on the steering wheel or on the belt or on the seat. In other words, in addition to making it audible by other road users in addition to this be made, for example, by a signal image on the vehicle display, the smartphone display or elsewhere within the vehicle is displayed. Alternatively or additionally, it would be conceivable that in dangerous situations the driver's attention is also aroused by a tactile stimulus, such as vibration of the bracelet or the belt or seat.

Advantageously, the acoustic output, in particular the design of the virtual sound source is standardized. It is conceivable to provide a danger object classification. It is also conceivable that the design of the virtual sound source is dependent on the classification.

When outputting a language, it can be done in different languages.

Preferably, the virtual sound source, in particular an output frequency spectrum, is adapted to a hearing ability, in particular to a frequency response, of a driver and / or passenger. Preferably, the output frequency spectrum is dependent on the age of the driver and / or passenger, for example, older drivers often hear worse than younger drivers.

Advantageously, the vehicle can transmit data calculated via a car-to-car communication to another vehicle, so that the other vehicle, for example via WFS, forms a virtual sound source. The calculated data is preferably calculated with respect to the other vehicle.
