Description
Technical field
The present invention relates to for the method for the Running noise coupling of electronic and/or motor vehicle driven by mixed power and device accordingly.
Background technology
, substantially there are two kinds of reasons in the essentiality for the motor noise of simulating vehicle.On the one hand, for the chaufeur to electronic or motor vehicle driven by mixed power provides the sensation that it is travelling, and provide and travel to such an extent that have a feedback of the sense of hearing how soon about it to it.On the other hand, other traffic participants thus, for example pedestrian and particularly blind person can hear vehicle electronic or that hybrid power drives.
At present, travel or the sound of motor noise generates and mostly according to rotating speed and/or speed, produces, strengthens and in car, transmitted and/or transmitted outward towards car for chaufeur and passenger.Also known so system, wherein makes sending of motor noise depend on and in environment, whether recognizes pedestrian.
US 2005/0200462A1 discloses the device that the existence of vehicle is shown for the environment to vehicle.Evaluation unit evaluation illustrates the essentiality of the existence of vehicle by means of the running noises of vehicle.
Summary of the invention
Under such background, by the present invention proposes according to the method for the coupling of the Running noise for electronic and/or motor vehicle driven by mixed power described in independent claims, having proposed according to the device of the use the method described in independent claims in addition.Each dependent claims and specification sheets below provide favourable design plan.
The present invention is based on following understanding, by by towards Che Nei with outside car travel or motor noise when it produces separated can Avoids or reduces except the environmental noise that always exists and the institute's N/R Running noise noise.Correspondingly, in speed, increase or during higher gear, the Running noise of the Chao Chenei increasing can provide corresponding driving experience for chaufeur, and increases or during higher gear, the Running noise outside car of minimizing can provide the noise protection at noise source place in speed.Correspondingly, along with the increase of speed, Running noise not automatically increases, and therefore on definite street, has reduced the burden of environment for use not.
In addition, according to mode described herein, proposed to produce dynamic rise or decline travel or motor noise to avoid beyond thought effect.That is,, if only connect and travel or motor noise for elec. vehicle, can cause so people's dangerous fright reaction when identifying people.This can be very important situation for blind person.
According to mode described herein, dangerous stage when Running noise-generation especially concentrates on travelling of vehicle.This stage is for example vehicle take-offs, running section at a slow speed, travel in city or travelling in 30-50km/h region.
The technical approach of the Sound Match for electronic or motor vehicle driven by mixed power described herein provides needed amount and the least possible Running noise.Except optimizing needed energy consumption for this reason and having completed electronics noise-proofing divider wall, with the combination of pedestrian's identification or with the combination of " city situation " identification be also possible.
The present invention has created the method for the Running noise coupling of electronic and/or motor vehicle driven by mixed power, there are following steps: based on motoring condition information and/or environmental information, obtain the inside noise data that travels, the wherein said inside noise data that travels limits the loudness of inner Running noise; Based on described motoring condition information and/or described environmental information, obtain the outside noise data that travels, the wherein said outside noise data that travels limits the loudness of outside Running noise; By the described inside noise data that travels, at first interface place, provide the inner space loud speaker to described vehicle; And at the second interface, provide at least one the space outerpace loud speaker to described vehicle by the described outside noise data that travels.
In order to be illustrated in elec. vehicle under electrical motor-pattern or the mobility operation of motor vehicle driven by mixed power for the chaufeur of vehicle and/or other the traffic participant in the environment of vehicle, elec. vehicle and/or motor vehicle driven by mixed power can have for generation of the device of Running noise or Running noise source.This Running noise additionally producing can be superimposed upon on the Running noise being produced by the operation of electrical motor.Device can be constructed, so that man-made land produces, travels or motor noise.Can also have with typically travelling or the data carrier of the record of motor noise.Running noise can for example be mated with following form about its loudness, and loudness can dynamically rise or decline according to predetermined factor.Can produce for the inner space of vehicle inner Running noise and be the environment of vehicle, for example for pedestrian and bicycle rider produce outside Running noise.Inner Running noise and outside Running noise can differently be mated about specifically changing dynamically of its loudness or its loudness.In order to mate Running noise, can analyze different signals or information.Motoring condition information can be for example about following information, and which gear the moving velocity of vehicle, for how high, has been used.Environmental information can be the data of for example camera towards environment of vehicle or by means of the navigation information of GPS and/or numerical map.Inner space loud speaker can be the loud speaker that is placed in chaufeur region, and space outerpace loud speaker can be the loud speaker of one or more environment towards vehicle.A plurality of inner spaces loud speaker can either be set, a plurality of space outerpace loud speakers also can be set, can be respectively by one or different interfaces, control those loud speakers.Vehicle can for example have at the space outerpace loud speaker in positive region with at another space outerpace loud speaker of the afterbody of vehicle.Inside noise data and the outside noise data that travels that travels can represent by electric signal, and those electric signals are suitable for controlling each loud speaker, are suitable for producing corresponding noise.
According to a form of implementation, motoring condition information can comprise about vehicle speed and/or the information of speed change gear.Environmental information can comprise street type information and/or object identifying information and/or ambient noise level.For example, can provide the information about speed by acceleration pick-up or the wheel speed sensor of vehicle.Information about speed change gear can illustrate, and has used which gear of vehicle.By using the location positioning by means of GPS and numerical map, can provide street type information by homing advice, whether vehicle is positioned at for example express highway, state county road or dwelling district.Be placed in camera in the external front face region of vehicle the information about the different objects in the adjacent ambient of vehicle for example can be provided.Can realize the identification to the object obtaining by means of camera by means of suitable object identification, object identification can provide object identifying information again.Object identifying information can be pedestrian identification, enter or leave the identification of cities and towns direction board or the identification of the building in the environment of vehicle, from this building, for example can release vehicle and be arranged in cities and towns.Correspondingly, the microphone being placed in perimeter can provide the information about the loudness of environment, for example, and the information of the loudness of the building noise in the adjacent ambient of vehicle.By those information, can advantageously realize according to the current place possessing and case conditions the coupling of inner Running noise or outside Running noise.For example, the identification of direction board " noise protection " can cause the decline of the loudness of outside Running noise.
For example, can so obtain the outside noise data that travels,, when motoring condition information and environmental information illustrate the city motion of vehicle, the loudness of outside Running noise is more than or equal to predetermined loudness.Predetermined loudness can limit fixing loudness value, and it is greater than zero.Alternatively, predetermined loudness can depend on the present speed of vehicle or depend on environmental characteristics.City motion can be limited to or general travelling of the vehicle in such environment in the cities and towns in,, in these environment, by means of outside Running noise, makes other traffic participants notice that vehicle is significant.Can provide and limit vehicle and be positioned at the corresponding environmental information outside Nei Huo cities and towns, cities and towns by navigationsystem or object means of identification.By this way, can guarantee to move in cities and towns once vehicle, vehicle sends outside Running noise with minimum loudness.Therefore can complete inevitable preventive, it stops vehicle to cross cities and towns with high speed " voicelessly ".According to an embodiment, when high speed or high gear, only, when the identification of place, building, street type information and/or place direction board is taken into account, realize closing or significantly reducing of Running noise.
Certain street that has classification " express highway, expressway ", the local popular building of process.In this kind of situation, the decline of the loudness in transitional region is significant.For the exception in the area of standing in great numbers at building in transitional region, outside Running noise can be positioned under predetermined loudness.Therefore on these sections, city, noise protection has preceence, and on those sections, it is essential the warning function of outside Running noise not to be considered as.
According to another form of implementation, when motoring condition information illustrates until the speed of First Speed threshold value while improving, the loudness of outside Running noise can rise.In addition,, when motoring condition information illustrates the speed raising from First Speed threshold value, the loudness of outside Running noise can remain unchanged or decline.In addition,, when motoring condition information illustrates the speed raising from First Speed threshold value, the loudness of inner Running noise can rise.For example,, within First Speed threshold value can for example be positioned at the maximum speed that cities and towns allow.Therefore the danger that, for example the rising of the loudness of the outside Running noise in the region between 0km/h and 50km/h can warn the pedestrian in cities and towns for example carefully to sail the vehicle coming thus.In particular, the dynamic loudness of Running noise that can be by the moving velocity along with increasing avoids pedestrian's scaring to affect, this scaring impact with may be for example in the situation that the scaring that unexpected use Running noise occurs from definite moving velocity affects the same.Because can indicate and leave cities and towns over First Speed threshold value, so promoting further of loudness is unnecessary or irritating.In contrast, the lasting rising of the loudness of the inside Running noise by the chaufeur place at vehicle, can advantageously adjust the sensation of travelling corresponding to moving velocity.By this way, chaufeur for example can be noticed intuitively the gearshift to higher gear that may need or surpass speed limit.
For example, when motoring condition information illustrates the motion of vehicle, can provide the inside noise data that travels.In addition, when motoring condition information illustrates that speed improves and/or during to the switching of higher speed change gear, the loudness of inner Running noise can rise.Advantageously, chaufeur can be for example corresponding to the use of throttle and obtain the feedback about the sense of hearing of its about moving velocity or acceleration/accel.
In addition,, when motoring condition information illustrates starting of the startup of electrical motor of vehicle and/or vehicle, can provide the outside noise data that travels.This provides following advantage, can make pedestrian for example or bicycle rider early notice the vehicle occurring in its vicinity.
According to another embodiment, when motoring condition information is shown to the switching of higher speed change gear, the loudness of outside Running noise can rise.The rising of loudness can continue, until reach predetermined speed change gear.Subsequently, when motoring condition information illustrates from predetermined speed change gear the switching to higher speed change gear and environmental information situation is shown outside city, the loudness of outside Running noise can decline again.Predetermined speed change gear can be the 4th gear of vehicle for example.Outside city, situation can be illustrated in the environment outside cities and towns.For example when illustrating state county road or object identifying information, street type information shows that disappearance during for typical building, can adopt situation outside city so for cities and towns.For the coordination of the redundant data of motoring condition information and environmental information, can think more definitely, during from the 4th gear to the five gears gearshift, vehicle is positioned at outside cities and towns, and therefore needn't consider high pedestrian's total amount.Correspondingly, at this, the decline of loudness is significant for the object of noise protection, and sufficient to guarantee is about the protection of other traffic participants.
Correspondingly, the loudness of outside Running noise is until rise in reaching the First Speed region of First Speed threshold value, if the speed that motoring condition information is illustrated in this First Speed region improves.Until reach in the second speed region of second speed threshold value, the loudness of outside Running noise can remain unchanged, if the further speed that motoring condition information is illustrated in this second speed region improves.Until reach in the third speed region of third speed threshold value, the loudness of outside Running noise can decline, if the further speed that motoring condition information is illustrated in this third speed region improves.And from reaching third speed threshold value, the loudness of outside Running noise can drop to zero or drop to the loudness lower than the original running noises existing, if motoring condition information illustrates, further speed improves and environmental information illustrates situation outside city from third speed region.Conventionally, vehicle is to be set to crossing cities and towns lower than the First Speed threshold value of for example 50km/h or lower than the velocity band of the second speed threshold value of for example 60km/h.At this, the lifting of the loudness of outside Running noise is for being significant to the warning of other traffic participants.For example, First Speed threshold value can limit the maximum loudness of outside Running noise.Between First Speed threshold value and second speed threshold value, can maintain the constant outside Running noise of size, so that constantly and make pedestrian and/or bicycle rider notice the vehicle of approaching from farther distance.In third speed region, can think comparatively safe, vehicle is positioned at outside city.Can in such degree, guarantee this viewpoint by the environmental information of situation outside city is shown, i.e. it is rational with roadable that the decline of loudness here can be considered to.At this, can be for example the identification of disappearance by the popular building in locality or the identification of leaving place direction board of carrying out situation outside city is shown.Can limit third speed region by second speed threshold value and third speed threshold value.Third speed threshold value is for example positioned at 80km/h.In the 4th velocity band, vehicle is positioned on state county road, Highway Main main line or express highway with very large probability, if again the disappearance by for example local popular building that correspondingly illustrated by environmental information confirm like that.In this velocity band, can perhaps fully close the outside Running noise additionally producing.Therefore provided the advantage of electronics noise-proofing divider wall, because Running noise no longer unnecessarily increases the burden of surrounding environment.
According to another form of implementation, when street type information illustrates predetermined street type and/or environmental information situation is shown outside city, the loudness of outside Running noise remains zero under speed drops to third speed threshold value time.For example when street type information and/or environmental information be illustrated on express highway travel and when moving velocity declines due to accident or construction site, this is favourable.At this, the rising of outside Running noise is nonsensical or irritating, because needn't consider pedestrian.
Alternatively, when object identifying information illustrates while recognizing from object in predetermined object type, the loudness of outside Running noise rises.So can and or for example also have the outside Running noise of animal additionally to improve warning function by near the people for vehicle.In contrast, if identify the object in object type, and those object types are considered to substantially outside Running noise not reacted, and the rising of the loudness of outside Running noise is nonsensical or unnecessary.Thus, provided in the following manner the advantage of improved noise protection, by this way can be in the situation that lack the loudness of the less outside Running noise of object maintenance in the environment of vehicle.While travelling in the relatively high cities and towns of the loudness of Running noise externally, this function can provide for resident the significant improvement of noise protection.
According to a form of implementation, in obtaining the step of the outside noise data that travels, can obtain for travel noise data and for the outside at the rear portion of the tail section exterior space loud speaker noise data that travels of the anterior outside of front space outerpace loud speaker, wherein so obtain the outside noise data that travels, when motoring condition information illustrates vehicle to overtake time, loudness that noise data limits is travelled higher than travel loudness that noise data limits and/or when motoring condition information illustrates vehicle travel backwards of the outside at rear portion in anterior outside, loudness that noise data limits is travelled lower than the outside at the rear portion loudness that noise data limits of travelling in anterior outside.Therefore the outside noise data that travels can be so provided, to overtake time, the loudness of outside Running noise at front space outerpace speaker higher than at tail section exterior space speaker, and when travelling backward, the loudness of outside Running noise at tail section exterior space speaker higher than at front space outerpace speaker.By using one or more fronts space outerpace loud speaker and one or more tail section exterior space loud speaker, can export the Running noise producing according to mode described herein orientedly.According to this form of implementation, Running noise can be mainly ring forward or backwards, in particular towards about the direction ring for other traffic participant potentially dangerous, relevant.In the positive side of vehicle, only can hear Running noise in a small amount.If the outside Running noise that the outside Running noise sound of exporting on the travel direction of vehicle is exported in the direction contrary with travel direction, has guaranteed for potential thus by the warning of the traffic participant that vehicle jeopardized and guaranteed for the noise protection that is not subject to dangerous traffic participant simultaneously.
In addition, the present invention has created the device for the Running noise coupling of electronic and/or motor vehicle driven by mixed power, and it comprises following characteristics: receiving device, for receiving motoring condition information and/or environmental information; First obtains unit, and for obtain the inside noise data that travels based on described motoring condition information and/or described environmental information, the wherein said inside noise data that travels limits the loudness of inner Running noise; Second obtains unit, and for obtain the outside noise data that travels based on described motoring condition information and/or described environmental information, the wherein said outside noise data that travels limits the loudness of outside Running noise; First provides unit, for the noise data that travelled in described inside, provides the inner space loud speaker to described vehicle at first interface place; And second provide unit, for by described outside Running noise second or other interfaces at least one the space outerpace loud speaker to described vehicle is provided.
Receiving device can be so to install, and by interface, is received and analyzed the device of incoming signal.For example by the navigationsystem of acceleration pick-up, light and sound transducer or vehicle, the form with motoring condition information and/or environmental information provides incoming signal.The first and second acquisition unit can be so to install, that by interface and receiving device, connect and separately by process the device of received information with different algorithms, to can obtain travel noise data and obtain the outside noise data that travels in the second acquisition unit of inside in the first acquisition unit.At this, first and/or second obtains unit can be connected with Running noise source or Running noise data bank by interface, can use Running noise source or Running noise data bank to obtain inside and/or outside Running noise.First and second unit is provided can be the contact of wire or contact, can inside and outside Running noise data be transferred to respectively to one or more inner spaces loud speaker and space outerpace loud speaker by it.
Therefore, this device can be understood to a kind of electric apparatus, and its processes sensor signal is also exported control signal accordingly.Described control setup can have can be with hardware mode and/or the interface of constructing with software mode.In the structure with example, in hardware, described interface can be for example a part for so-called ASIC system, the various functions that described ASIC system comprises control setup.Yet also possible that, described interface is distinctive, integrated circuit or separate member, consists of at least in part.In the structure with form of software, described interface can be software module, and described software module is for example present on the microcontroller that also has in addition other software modules.
