Description

The invention relates to a method for quenching wild animals for a motor vehicle.While motor vehicles are increasingly being equipped with more and more sensor systems for an ever-advancing automation of the driving operation, certain safety aspects of the driving operation are difficult to automate. This includes, in particular, the encountering of motor vehicles with wild animals, which can lead to partially serious accidents again and again via direct collisions on the one hand, but also via uncontrolled avoidance movements of the driver on the other hand. As a result of the habitats of wild animals and their walking behavior, such accidents occur in particular on country roads and circular roads, where any medical care of an victim of an accident is often still made more difficult by the distance from the closest larger locality or from the next ballistic area. Moreover, unlike federal roads, country and circle roads are often only insufficiently secured against wild changes with corresponding barriers such as fences.The problem of wild accidents relates on the one hand to the owners of the vehicles involved, who are exposed to a risk for their health as a result of an impact (or secondary accidents as a result of a tearing of the control etc.), and in addition, if applicable, to have to carry the economic damage to the own vehicle. On the other hand, wild accidents are also a serious problem from the standpoint of animal protection, since the animals involved usually do not survive an impact and at the same time do not rarely have to suffer significantly.There are currently various approaches to reduce wild accidents. In particular, on routes with frequent wild changes, in addition to the marking, static warning devices are installed, which are intended to irritate the wild and thus ideally to bring about a careful crossing of the roadway. In this case, on the one hand, optical stimuli are used as warning means, for example, in that the headlight light of an approaching vehicle is reflected or scattered into wide regions laterally of the roadway by mirrors, prisms, reflectors or the like fastened to the edge of the driving belt (for example, at line-limiting posts). The light reflections can then trigger the desired response in wild animals. Olfactory stimuli are likewise possible as warning means, for example in the form of scents which secrete a quenching secretion.Acoustic stimuli in the form of warning tones can be emitted by special sound generator arrangements on the roadway, which are activated by an approaching vehicle by a light barrier system of the arrangement.Common to the solutions mentioned is that the desired effect is produced by a device preinstalled at a fixed point, which considerably restricts the effective radius.On the other hand, in-vehicle solutions would require continuous detection of the vehicle environment by cameras and continuous detection of wild animals in the camera images in order to be able to output warning tones as required. For reliable detection, use would be made here of thermal imaging cameras, which however, for cost reasons, are currently not yet used in motor vehicles to cover the surface. A permanent output of such warning tones may not be eligible for reasons of protecting other animals (pasture animals, birds, etc.) in the area of the road.DE 10 2016 001 773 A1 mentions a method for generating an acoustic signal for emission into the external environment of a vehicle, the signal being generated as a function of a detection of the environment in the vehicle. The method is characterized in that traffic sign recognition is carried out via the environment detection, wherein signal generation in the frequency range of the ultrasound is started whenever a traffic sign has been recognized which indicates a risk due to wild changes. The emission of the signal can be prevented in this case in orthodyes.Also mentioned in DE 10 2004 050 597 A1 is a similar wild-type alternating warning device for a motor vehicle, which device comprises sensor systems for detecting wild that occurs. A comparable wild-type change warning system is also shown in DE 10 2022 002 339 A1.DE 10 2009 037 170 A1 mentions a similar warning system for a motor vehicle, in which an acoustic signal is output on the basis of environmental parameters which are detected by a sensor device in order to ensure improved safety of the vehicle occupants and of the persons and animals present in the environment of the vehicle. Warning systems comparable to this are also disclosed in DE 10 2018 222 003 A1, DE 10 2010 043 212 A1 and DE 10 2009 057 683 A1.The invention is therefore based on the object of specifying a method for a motor vehicle (motor vehicle) by means of which wild animals can be quenched as required and nevertheless reliably as possible in order thus to avoid a collision with the motor vehicleThe object mentioned is achieved according to the invention by a method for quenching wild animals for a motor vehicle, wherein a risk potential for a collision with a wild animal is detected, wherein a noise generation module of the motor vehicle generates a quenching noise upon detection of the risk potential, and wherein the generation of the quenching noise is automatically prevented if a presence of a pet and / or of a livestock animal in an interior of the motor vehicle and / or in a trailer of the motor vehicle is detected or assumed. Advantageous and partly per se inventive embodiments are the subject matter of the dependent claims and of the following description.The motor vehicle can be provided here by any type of motor vehicle, i.e. in particular by a passenger car. The motor vehicle can also be a truck. The motor vehicle can have any form of motorization, i.e. for example internal combustion engines and / or electric drives, etc. A wild animal preferably comprises any non-domestic animal living in a free wild lane, not serving as a domestic or livestock animal and suitable according to its size and weight for causing a not inconsiderable damage in the event of a collision with the motor vehicle. In particular, a wild animal includes an animal subject to the respectively applicable jagd law, but this law is not intended to be restrictive. In particular, wild animals include red and damhirches, rehe, wild swine, elche, baries, etc., but also other animals, for example small mammals such as fruit or rabbits, or also animals which may optionally be under animal and / or species protection, such as species of rare wild cats, luchses or fish pots.In this case, a preferably quantitative variable is included as the risk potential, which specifies a measure for the possibility of a collision, or depends monotonically on such a measure. The collision is not necessarily the case here in a collision; in particular, such a collision also includes a driver of the motor vehicle being forced to change his travel trajectory due to the presence of a wild animal in the region of the roadway for safety reasons (for example, in order to anticipated movements of the wild animal or to pass the wild animal with a safety margin), even if a collision would not necessarily take place while maintaining the trajectory.A noise generation module includes in particular any device which is suitable for generating the quenching noise and is correspondingly configured, for example, by loudspeakers, membranes, control electronics, etc. The quenching noise is preferably suitable in its type (i.e., in particular in its frequency spectrum, its modulations and its level) for quenching wild animals and thereby for smuting them and / or irritating them to such an extent that the wild animals continue to move only with increased caution, and in particular no longer absorb a fast running movement. Preferably, when generating the quenching noise, a possible Doppler effect on the frequency spectrum and, if appropriate, on the modulation thereof is to be taken into account.Included among a pet are, in particular, cats, dogs, small animals such as hamsters, guinea pigs, rabbits, etc., and ornamental birds. Among a livestock animal are included in particular animals for agricultural food production such as cattle, pigs, sheep, goats, chickens. A presence of a pet in the interior of the motor vehicle or of a livestock animal in a trailer of the motor vehicle can be detected directly, in particular, or can also be assumed on the basis of the circumstances detected (for example by means of a camera) or detected (for example from map data).The invention achieves the object in that, on the one hand, the quenching noise for quenching wild animals is only generated if, as a result of the external circumstances, there is at all a sufficiently high risk for a collision or a collision with a wild animal. This makes it possible to conserve wild animals off the roadway and other animals close to the roadway. On the other hand, the quenching noise is deactivated as required if a pet in the motor vehicle and / or a livestock animal in the vicinity of the motor vehicle could be annoying due to the quenching noise. A further advantage is that the quenching is effected by the motor vehicle itself, so that the effectiveness no longer depends on the number of stationary units for quenching set up.The risk potential is preferably recognized on the basis of at least one traffic sign and / or on the basis of a sign stored in map data, which has a relationship to wild animals, and / or on the basis of wild change information, which is provided by an authority and / or a cast. Such a traffic sign can be given, for example, by a warning sign "Caution Wild Change"; comparable information can also be stored in map data, for example of a navigation system. In this case, the at least one traffic sign is particularly preferably recorded by means of a front camera of the motor vehicle, and / or the sign stored in map data is recorded by means of a navigation system. The risk potential is then detected, for example, on the basis of an image recognition of the traffic signs in the image data. The wild change information can be provided in particular by an authority, e.g. a community, a traffic authority, a police authority, a country council, a forstamt or an environmental authority, or by a relevant association such as a local jagd association or animal protection association, and e.g. via a corresponding server, or by integration of the wild change information into further traffic information obtained and used by the navigation system, or by other web-based, in particular interactive map services (i.e. not integrated into the navigation system).Alternatively or in addition to the means described here, the risk potential can also be carried out on the basis of a radar sensor and / or a lidar sensor and / or a thermal imaging camera, preferably with a corresponding automatic image recognition, wherein the type of sensor system is preferably matched to the information to be obtained (for example a direct recognition of wild animals with the aid of the thermal imaging camera).Advantageously, a current time of day and / or a brunft period of wild animals is taken into account for the detection of the danger potential. In particular, for this purpose, the time of day and / or a current date are compared with stored statistical data about the migration behavior of wild animals at specific day and / or seasons, and are optionally compared with stored brunft periods (for example: increased probability of brunft time; particular times of day for individual wild animal types, etc.).Advantageously, the noise generation module generates artificial driving noises at least temporarily during the normal driving operation of the motor vehicle, which in particular do not serve the object according to the invention. This can be the case in particular if the motor vehicle is provided by an electrically driven vehicle (purely battery-electric vehicle or even hybrid vehicle with an additional internal combustion engine), so that the artificial driving noises are intended to increase an attention of pedestrians who could otherwise notice the motor vehicle too late, if necessary, as a result of missing motor noises of an internal combustion engine, as a result of which a hazardous situation could arise.Expediently, a sound, in particular a sinusoidal sound, with a fundamental frequency above 15 kHz, preferably above 20 kHz and in particular also below 100 kHz, preferably below 50 kHz and particularly preferably below 30 kHz is used as quenching noise. Said frequencies are particularly suitable for inducing the desired response in wild animals. It is also possible to use preferably sounds and / or noises which have short pauses and / or frequency changes such as jumps in order to make it more difficult for the wild animals to become accustomed to the quenching sound.It has proven to be further advantageous if a gradual value for the danger potential is determined, and, in particular above an activation threshold for said gradual value, a level strength of the quenching noise is set in a monotone dependent on said gradual value. This follows the consideration that it is considered tolerable for a particularly critical situation, for example a virtually reliably imminent collision, to set the sound level of the quenching noise particularly high and thus to subject other animals at a relatively remote location (unintelligent wild animals or else farm animals) to an increased nuisance by noise in the short term in order to protect the involved wild animal and also the driver of the motor vehicle from the imminent collision.In an advantageous embodiment, a presence of a pet and / or livestock animal is detected by means of an interior camera and / or the or a front camera of the motor vehicle, and / or is detected on the basis of map data relating to agricultural fields of use. For the capturing of the pet by means of the interior camera or for the capturing of livestock by means of the front camera, the explanations apply in particular for capturing the traffic sign or a wild animal by means of the front camera. For the detection of the livestock animal on the basis of map data on agricultural fields of use, the statements apply in particular for the detection of a sign stored in map data with reference to wild animals.Expediently, when a trailer is coupled, preferably via an interface (for example in the dashboard), a user request about the presence of a pet and / or livestock in the trailer is issued to a driver of the motor vehicle, and the generation of the quenching noise is automatically deactivated in the event of a positive response of the driver to said user request. Thus, when a trailer is attached to a trailer hitch or the like of the motor vehicle, the driver is prompted to confirm whether a livestock (or a pet) is present in the trailer. In this case, generation of the quenching sound is automatically disabled.The invention further provides a motor vehicle comprising means for detecting a risk potential for a collision with a wild animal, a noise generation module for generating a quenching noise, means for detecting a presence of a pet and / or a livestock animal in an interior of the motor vehicle and / or in a trailer of the motor vehicle, and a control unit, wherein the motor vehicle is configured to carry out the method described above.The motor vehicle of the invention shares the advantages of the method of the invention for quenching wild animals. The advantages specified for the method and for its developments can be transferred analogously to the motor vehicle.An exemplary embodiment of the invention is explained in more detail below with reference to drawings. Here, in each case, diagrammatically show: FIG. 1 is a block diagram of a motor vehicle on a country road on which a collision with a wild animal is imminent; and FIG. 2 is a block diagram of a method for quenching wild animals for the motor vehicle according to FIG. 1.Mutually corresponding parts and sizes are each provided with the same reference numerals in all figures.FIG. 1 schematically shows a block diagram of a motor vehicle 1 which is located on a country road 2. The motor vehicle 1 is provided in the present case by an electric vehicle (purely battery-electric vehicle or also hybrid vehicle with an additional internal combustion engine), but neither the invention nor the present exemplary embodiment are limited thereto. The motor vehicle 1 comprises, among other things, a front camera 4, which is directed at an area 6 of the country road 2 lying in front of the motor vehicle 1 and its direct environment 8. The front camera 4 can also be formed by a plurality of individual camera elements (not shown), which are aligned to capture the mentioned region 6 and which are arranged distributed over the front region 10 of the motor vehicle 1.Motor vehicle 1 further comprises a navigation system 12 having a memory 14. Map data 16 are stored in the memory 14, which also contains, among other things, the country road 2 on which the motor vehicle 1 is currently located. The navigation system 12 comprises a GPS localization system, not shown in detail, for determining a current position of the motor vehicle 1 in order to classify it in the map data 16. The navigation system 12 is further connected to a communication device 18 of the motor vehicle 1, which may be provided, for example, by a WLAN-capable antenna, and via which current traffic information (for example regarding traffic jams or road barriers) and possibly further information relevant to a driver of the motor vehicle 1 in connection with the travel path can be obtained.The front camera 4 is connected to an image recognition device 20, which is provided and configured to recognize objects relevant to the driving operation in the image data of the respective region 6 generated by the front camera 4. The image recognition device 20 is further connected to a control unit 22, in the present case the aforementioned objects recognized by the image recognition device 20 are evaluated in the control unit 22, and, if applicable, specific driving functions are controlled. For example, the objects can be provided by road boundaries (not shown) or vehicles driving ahead, so that in the event of an imminent loss of the lane, a warning function for the driver and / or an automatic counter-steering or automatic braking is activated by too great an approach to such a road boundary, or if the distance from the vehicle driving is too small.The image recognition device 20 can be implemented in particular on the same physical structure as the control unit 22, In particular, the same computational resources such as processor cores, working memories, etc. can be used here, or the image recognition device 20 can be implemented as a corresponding program module of the control unit 22.The control unit 22 is also connected to a timer system 24 which indicates a time 26 and furthermore comprises a calendar 28. The timer system 24 can be implemented physically in the control unit 22 itself, or else in the structures another, further control unit (not shown), which is provided and configured for actuating other functions of the motor vehicle that are not mentioned in more detail here.A danger potential for a collision with a wild animal is now determined on the basis of the front camera 4 and / or on the basis of the navigation system 12. This can be done on the one hand by the front camera 4 capturing a traffic sign 30 which has a relationship to wild animals, that is to say, for example, a warning sign for a wild change. A recording of the front camera 4 is now analyzed by the image recognition device 20 for the presence of objects relevant to the driving operation. In this case, the traffic sign 30 is recognized, and its content-i.e. the warning about a wild change-is detected and sent to the control unit 22. Such a traffic sign 30 can likewise be stored as a "virtual" sign 32 in the map data 16 of the navigation system 12. The virtual sign 32 can also correspond to an associated physical traffic sign 30 on the country road 2. However, the sign 32 can be detected by the navigation system 12 in particular redundantly with respect to the detection of the traffic sign 30, in order to increase the reliability of the detection, for example in the event that the light conditions are unfavourable, which then impairs the quality of the recordings of the front camera 4. If the wild change is identified in the aforementioned manner, the risk potential for a collision with a wild animal is thus determined. Alternatively or in addition to the means described here, the risk potential can also be carried out on the basis of a radar sensor and / or a lidar sensor and / or a thermal imaging camera (in each case not shown), preferably with a corresponding automatic image recognition, wherein the type of sensor system is preferably matched to the information to be obtained (for example a direct recognition of wild animals with the aid of the thermal imaging camera).Alternatively or additionally to the above-mentioned procedure, a direct recognition of a wild animal 34 in the area 6 in front of the motor vehicle 1 next to the country road 2 can also be carried out by the image recognition device 20 in the images of the front camera 4. However, such a detection may only be successful during the day and without fog or other visual impairment such as heavy rain, since on the one hand the detection, in particular at a distance beyond a light cone of the headlights (not shown in each case) of the motor vehicle 1, is only sufficiently reliable in the case of sufficient daylight (at a shorter distance one might no longer have sufficient room for action over time), and on the other hand wild animals are more likely to be brought to remain on the roadway in a shocky manner by said headlights. Similarly, alternatively or in addition to the mentioned traffic information or for the direct detection of wild animals, a piece of wild change information 36 can be obtained via the communication device 18, which is provided for example by an authority (such as e.g. a town, a land toll or a forstamt etc.) or a relevant association (such as e.g. a local jagd association or animal protection association). The provision can be effected, for example, via a corresponding server, by integration of the wild change information 36 into further traffic information obtained and used by the navigation system 12, or via other web-based, in particular interactive map services (i.e. not integrated into the navigation system 12).In order to identify the risk potential for a collision with a wild animal 34 as reliably as possible, the time 26 given by the timer system 24 and / or the given date of the calendar 28 can furthermore be taken into account. In particular, for this purpose, the time 26 and / or the date are compared with stored statistical data (not shown) about the walking behavior of wild animals at specific day and / or seasons (for example: increased probability of the time of brunning; particularly critical months such as April / May; particularly critical times such as 5 to 7 am and 21 to 23 am; consideration of time changeover which could suddenly place a walking period of wild animals into the rub-house; particular times of day for individual wild animal species etc.).Motor vehicle 1 further has a noise generation module 38 which is connected to control unit 22. The noise generation module 38 is provided and configured to generate artificial driving noises during the electric driving operation of the motor vehicle 1 in order to increase an attention of pedestrians who might otherwise notice the motor vehicle 1 too late as a result of missing engine noises of an internal combustion engine, as a result of which a hazardous situation could arise. The generation of the artificial driving noises can be limited here in particular to specific driving speeds (assuming that driving by orthodontists with pedestrians can be ruled out starting from a specific driving speed). The generation of the artificial driving noises can be controlled by the control unit 22 or by a different method than the control unit 22.If the risk potential is now considered sufficiently high by the control unit 22, and thus a collision with a wild animal 34 (at least implicitly) is sufficiently likely, the control unit 22 causes the noise generation module 38 to generate a quenching noise 40 by a corresponding control signal (not shown), which is suitable for distributing the wild animal 34 from the direct environment 8 of the agricultural roadway 2 and / or for increasing the attention of the wild animal 34 located next to the agricultural roadway 2, and thus for preventing it from entering the roadway. The quenching noise 40 is preferably given by a sound 42 having a frequency of preferably above 20 kHz (in particular below preferably 50 kHz), and particularly preferably outside the human auditory spectrum.For the generation of the quenching noise 40, there is also an upstream safety or deactivation barrier described below: the presence of a livestock and / or pet. In order to prevent a pet (not shown) carried in the motor vehicle 1 from being annoying or even damaged by the quenching sound 40, the presence of a pet is monitored. For this purpose, the motor vehicle 1 comprises an interior camera 44, which is provided and configured to capture the interior of the motor vehicle 1. In a manner comparable to the front camera 4, the interior camera 44 can be formed from a plurality of camera modules (not shown) for better capturing of the entire interior, which camera modules capture the interior from different viewing angles. The image recordings of the interior camera 44 are preferably evaluated by the image recognition device 20 in order to recognize the presence of a pet.If a pet is detected, the generation of the quenching noise 40 is automatically prevented by the control unit 22, or the function of the generation is temporarily deactivated.In a comparable manner, it can be detected on the basis of the image recordings of the front camera 4 whether the land road 2 is just passing an agricultural pasture surface or the like, so that as a result of an assumed or also real detected presence of farm animals, the generation of the quenching noise 40 is automatically prevented by the control unit 22. In this case, e.g. a pasture fence can be easily recognized and the assessment can be confirmed if livestock in the vicinity of the pasture fence are additionally detected. However, the information about the agricultural pasture area can also be obtained from the map data 16 of the navigation system 12 and / or via the communication device 18 (for example from agricultural associations).Moreover, the presence of a livestock animal can also be detected by a user request, which is output to the driver via a suitable interface 48 (e.g. touchscreen in the dashboard) of the motor vehicle 1 when a coupling of a trailer (not shown) to a trailer coupling 50 of the motor vehicle 1 is detected (for example detected as a confirmation request: "trailer". If a (useful) animal is in the trailer? Y / N). Upon confirmation of the request, the generation of the quenching sound 40 is automatically prohibited or deactivated by the control unit 22.FIG. 2 shows a block diagram schematically of the sequence of a method for quenching wild animals for a motor vehicle, in particular for the motor vehicle 1 according to FIG. 1 The front camera 4 generates image data Img, which are analyzed by the image recognition device 20 for traffic information relating to wild changes (such as the traffic sign 30) and / or for a direct presence of a wild animal 34 in the region 6 in front of the motor vehicle 1. The analysis results ImgAna are passed to the control unit 22. Alternatively or additionally, traffic information about wild-type changes (such as virtual sign 32) may be detected by navigation system 12. The corresponding information NaviAna is also forwarded to the control unit 22. In addition, the above-mentioned compounds may be used. Wild change information 36 provided by authorities and / or associations or the like can be obtained via the communication device 18 and passed on to the control unit 22.On the basis of the analysis results ImgAna of the image data Img, and / or on the basis of the information NaviAna of the navigation system 12, and / or on the basis of said wild change information 36, a risk potential GW for a collision with a wild animal is now determined. For this purpose, the time 26 and the date provided by the timer system 24 can also be taken into account.The danger potential GW is determined in the present case from the mentioned information as a gradual value, i.e. for example, with suitable normalization as a probability for a collision with a wild animal 34.For the deactivation condition Cnd, image recordings Imgnt of the interior camera 44 can be examined by the image recognition device 20 for a presence of a pet in the interior, and / or the image recordings Img of the front camera 4 can be examined for an agricultural pasture area or a presence of farm animals, and / or information on an agricultural pasture area can be obtained from the map data 16 of the navigation system 12 and / or via the communication device 18. Moreover, if a trailer coupling to the trailer coupling 50 of the motor vehicle 1 is detected, the user request Q can be issued to the driver via the interface 48 whether a livestock animal is located in the trailer. In the case that a pet in the interior is detected, an agricultural pasture area adjacent to the country road 2 is detected, or a presence of a livestock animal is detected or confirmed, the deactivation condition Cnd is fulfilled (y) and no further action takes place despite a detected danger potential GW.If, however, the deactivation condition is not fulfilled (n), then the quenching noise 40 is generated by the noise generation module 38 when the risk potential GW is detected. In particular, the higher the risk potential GW is evaluated, the louder the quenching noise 40. In particular, the present deactivation condition Cnd(y) for a fail safe mode can also be matched if the risk potential GW exceeds a critical value. In this case, it is assumed that a collision with a wild animal is highly probable or virtually unavoidable, so that an annoying of domestic and / or livestock in the immediate vicinity of the motor vehicle 1 appears to be tolerable exceptionally.Although the invention has been illustrated and described in more detail by the preferred exemplary embodiment, the invention is not restricted by the disclosed examples and other variations can be derived therefrom by the person skilled in the art without departing from the scope of protection of the invention.List of reference characters1 Motor vehicle (motor vehicle) 2 Country road 4 Front camera 6 Area (in front of the motor vehicle) 8 Direct environment (of the country road) 10 Front area (of the motor vehicle) 12 Navigation system 14 Memory 16 Map data 18 Communication device 20 Image recognition device 22 Control unit 24 Timer system 26 Time 28 Calendar 30 Traffic sign 32 (virtual) sign 34 Wild animal 36 Wild change information 38 Sound generation module 40 Quenching sound 42 Sound 44 Interior camera 48 Interface 50 Trailer coupling Act Activation limit Cnd Deactivation condition GW Risk potential Img Image recording (of the front camera) ImgAna Analysis results Imglnt Image recording (of the interior camera) NaviAna Information (of the navigation system) Q User request
