As described above, at present, with the development of cities, roads in cities become more and more crowded. If a pedestrian does not notice that the pedestrian stands in front of the vehicle or occupies the road and does not give way voluntarily, if the user directly presses the horn to give out a warning, the pedestrian in front is very likely to be frightened by excessive whistle, especially on some very obscure roads, and the excessive whistle can even injure the ears of the pedestrian directly exposed in the whistle. In addition, in the traffic environment where vehicles are endless, pedestrians are easy to make a panic behavior once being scared, and the possibility of causing some unexpected traffic accidents is further increased.
In order to solve the above problems in the prior art, the invention provides a method and a device for controlling vehicle whistle volume and a vehicle comprising the control device. By implementing the control method, the invention can identify the living objects existing ahead in time in the driving process of the automobile and automatically turn down the volume when the automobile whistles, thereby realizing warning of avoidance of the living objects and avoiding accidents caused by the fact that ears of the living objects are damaged or the living objects are scared.
In some non-limiting embodiments, the control method of the vehicle blast volume provided by the first aspect of the present invention may be implemented by the control device of the vehicle blast volume provided by the second aspect of the present invention. The vehicle whistle volume control device according to the second aspect of the present invention is provided in the vehicle interior according to the third aspect of the present invention, and the vehicle whistle volume control method is executed by the vehicle whistle volume control device. Specifically, the control device for the vehicle whistle volume is provided with a memory and a processor.

The processor is connected with the memory and configured to execute the computer instructions stored in the memory so as to implement the above-mentioned control method for vehicle whistle volume according to the first aspect of the present invention.
The operation principle of the control device for the vehicle whistle volume will be described below with reference to some embodiments of the control method for the vehicle whistle volume. It will be appreciated by those skilled in the art that these examples of the method for controlling the volume of a vehicle whistle are merely non-limiting embodiments provided by the present invention, which are intended to clearly illustrate the broad concepts of the present invention and provide specific embodiments for facilitating the implementation by the public, rather than limiting the overall operation and functionality of the control device for the volume of a vehicle whistle. Similarly, the control device for vehicle whistle volume is only a non-limiting embodiment provided by the present invention, and does not limit the main implementation of each step in these control methods for vehicle whistle volume.
Referring to fig. 1, fig. 1 illustrates a flow chart of a method for controlling a vehicle blast volume according to an aspect of the present invention. As shown in fig. 1, the method for controlling the whistling volume of a vehicle mainly comprises the following steps:
s110: in the running process of the vehicle, a first whistle instruction is sent out in response to a user, and whether a living object exists in the front of the vehicle within a preset distance range or not and whether the current vehicle speed is smaller than a first speed threshold value or not are judged.
In some embodiments of the present invention, during the driving process of the vehicle, it is often the case that a pedestrian or a living object such as a small animal occupies the road ahead and does not give way actively or does not give way in time. In this case, the owner of the vehicle will typically press the horn of the vehicle directly to alert the pedestrian or small animal ahead to avoid.
The decibel value of normal domestic car horn is about 85-115 decibels, and the decibel value of the whistle of truck is greatly over 110 decibels. The horn standard of the ministry of industry and communications in 2021 for the motor vehicle is adjusted up to decibel value, the motor vehicle is required to reach 105-118 decibels, thereby the horn standard can give full warning to the front vehicle in the driving process.
An upper limit of 40 to 60 db is an acceptable level for human ear. When the sound is below 40 decibels, the sound has no influence on human bodies. Sounds are awake at 40-60 db, but if a person is in this environment for a long time, the nervous system is affected. Then, the noise energy is doubled every 3 db of noise improvement on average. When the sound reaches 65 dB to 80 dB, people can be nervous and uncomfortable for a long time. When the noise exceeds 90 decibels, the ears are itchy and painful, and even the hearing of people is greatly damaged.
However, since the horn of the vehicle is used in a traffic environment and plays a significant role in terms of personal safety, the priority of safety is higher than comfort with respect to the sound volume of the horn of the vehicle. However, if the horn is pressed directly in the current vehicle whistling pattern, the vehicle horn will immediately sound a whistling sound in excess of 85 decibels, which is a normal volume whistling for warning the vehicle in front, but the ears of these living objects are directly and closely exposed to the whistling sound of the car if a pedestrian or animal is in front. This sudden whistle sound of over 85 db not only harms their hearing, but also tends to startle the living objects ahead. In such a frightened situation, both pedestrians and animals are likely to make a panic, thereby increasing the likelihood of causing some unexpected traffic accidents.
In view of the above problems in the prior art, in some embodiments of the present invention, whether a living object such as a pedestrian or a small animal approaches around a vehicle is detected by providing a sensor capable of sensing the approach of the living object on the vehicle.
In some embodiments of the invention, a human proximity sensor is provided on the vehicle. Can also accurately detect being close to of pedestrian or other animal life through human proximity sensor under the dim condition of external environment light to whether there is the life object around can further judging the vehicle.
The human body proximity sensor is based on the Doppler technical principle and adopts a special microwave microprocessor and a planar induction antenna. Common frequency bands of 5.8GHz, 10GHz and 24GHz adopt the Doppler principle, when an object moving in a certain range around is detected, a circuit is triggered to work, the target speed is obtained, the radar signal waveform is changed, and therefore the action of a radar sensor is triggered. The human body proximity sensor is characterized in that the human body proximity sensor can sense moving life objects, can be installed in a hidden way and can sense through plastics; however, it has the disadvantage that it cannot sense a static living object, such as a human or an animal in a sleeping state.
In other embodiments of the present invention, an infrared sensor may be disposed on the vehicle to determine whether there is a living object around the vehicle. The infrared sensor adopts a pyroelectric infrared induction principle, and triggers the sensor to act by collecting the change of infrared energy. Since human and animal bodies have constant body temperatures, generally 36-37 degrees, the infrared sensor emits infrared rays with specific wavelengths, and the passive infrared probe detects the infrared rays emitted by the human body to operate. The infrared sensor is influenced by the ambient temperature, and when the ambient temperature in summer is close to the body temperature of a human body, people do not have infrared energy change when entering an induction range, so that the human body induction performance of the infrared sensor in summer is not sensitive.
In other embodiments of the present invention, a PCR radar sensor may be configured on the vehicle to determine whether there is a living object around the vehicle. The PCR radar sensor is a millimeter wave radar sensor with an on-chip integrated antenna, and works in an ISM free frequency range of 61GHZ. The principle is that the ultra-wideband is utilized to perform high-precision micro-motion detection, and then the respiration signal of a living object can be detected. Because the PCR radar sensor can adopt a battery to supply power, the sensor is widely suitable for scenes such as intelligent wearing, mobile equipment, intelligent home, internet of things and the like, can detect moving life objects and can also detect static or deep-sleep life objects.
Of course, the method for determining the presence or approach of a pedestrian in the present invention is not limited to the above-mentioned embodiments, and any method capable of determining whether a living object is approaching is within the scope of the present invention.
The sensor can effectively detect whether a living object is close to the periphery of the vehicle, and in order to further know the environment condition around the vehicle, it is preferable that in some embodiments, 4 180-degree wide-angle cameras are installed in the front and at the back and on both sides of the exterior of the vehicle to obtain a 360-degree panoramic image around the vehicle.
The 360-degree panoramic image is used for recording all image information of the front, the back, the left and the right of the vehicle at one time, and no post-synthesis and multi-lens splicing are performed. The principle is that 360-degree horizontal and 180-degree vertical information is imaged at one time by adopting a physical optical spherical mirror transmission and reflection principle according to bionics (fish eye structure), and then software carried by hardware is adopted for conversion, so that a picture is presented in a human eye habit mode.
Generally speaking, a panoramic image has 4 cameras all around, and the two cameras are respectively arranged at the head of a vehicle, a parking space and under two reflectors at two sides and are respectively used for collecting images of the conditions of the head of the vehicle, a blind area at the side of the vehicle and the tail of the vehicle. The 4 wide-angle cameras with 180 degrees simultaneously acquire real-time images of all parts around the vehicle, and transmit the images of all the parts to the image processing unit.
And transmitting the images acquired by the 4 wide-angle cameras to an image processing unit for image processing correction and splicing. Because a 180-degree wide-angle camera (also called a fisheye wide-angle camera) is adopted to ensure that the visual field is large enough, the shot images are distorted somewhat, and geometric correction is needed. Specifically, the same points in the image are processed through software, operations such as distortion reduction, visual angle conversion and the like are carried out on the same points, the overlapped areas of images with specific angles are accurately integrated, and finally a panoramic top view of the periphery of the vehicle is displayed on a screen, so that the position and the peripheral condition of the vehicle are visually presented.
A360-degree panoramic image function is configured on the vehicle, so that A/B/C column blind areas, head/tail blind areas and rearview mirror blind areas outside the vehicle can be eliminated. These blind areas can result in the user not seeing the obstacles and being prone to danger of colliding with pedestrians, animals and other vehicles. The 360-degree panoramic image eliminates the possibility that the blind area cannot be seen, and further ensures the safety of the vehicle, the pedestrians, animals and the vehicles around the vehicle in the driving process.
In this embodiment, through 360 degrees panoramic imagery, the user can see the vehicle in-process around object and the life object on the car machine display screen. The surrounding objects mainly include vehicles around and other immovable obstacles, and the living objects mainly include pedestrians, animals and the like. The method for controlling the whistle volume of the vehicle provided by the invention is further described below by taking a pedestrian as an example.
Preferably, in some embodiments, the car machine system is further equipped with an image recognition function. The vehicle-mounted device system can identify the identity of the life object around the vehicle in the obtained 360-degree panoramic image around the vehicle through the image identification function. Specifically, if a pedestrian exists in the acquired 360-degree panoramic image, the pedestrian can be identified through face recognition in the image recognition function. For example, 3 pedestrians appear in the panoramic image, and are identified and respectively marked as a pedestrian a, a pedestrian B and a pedestrian C through the face recognition function. Similarly, if there is an existing animal in the acquired 360-degree panoramic image, the animal can be identified by the animal identification in the image identification function and marked respectively.
In some embodiments, during driving, when the user finds that an obstacle exists in front of the vehicle, such as other vehicles, pedestrians, animals or the like, a whistle command is given, and the vehicle immediately enters a state of being whistled. And the vehicle further confirms that an obstacle exists in a specific distance range in front through the vehicle-mounted system, and then performs whistle operation.
Alternatively, in other embodiments, the user may issue a whistle command as soon as the vehicle is started, and the whistle operation is performed directly when the vehicle finds that there is an obstacle in a certain distance range ahead. The vehicle enters a state of preparing for whistling after receiving the whistling instruction issued by the user.
After the vehicle enters a ready-to-whistle state, the vehicle-mounted machine system judges the state of the surrounding environment where the vehicle is located at present, and therefore whether the vehicle needs to execute a first whistle instruction or not is determined. In this embodiment, the conditions for the main judgment as to whether the vehicle needs to perform the first whistle operation include: whether a pedestrian exists in a preset distance range in front of the vehicle and whether the current vehicle speed is smaller than a first speed threshold value.
In some embodiments of the present invention, the vehicle-mounted device system determines whether there is a pedestrian around the vehicle or not by using the sensor. Further, according to a 360-degree panoramic image acquired by a camera mounted outside the vehicle, the vehicle-mounted system can identify the identity of a pedestrian near the vehicle in the panoramic image through an image identification function.
In the above embodiment, the sensor for determining and identifying the living object and the 360-degree panoramic image function may be turned on after the user issues the whistling instruction, turned off after the vehicle performs the whistling operation for the time, and turned on again until the user issues the whistling instruction for the next time. Optionally, the sensor and the 360-degree panoramic image function may be turned on after the user issues a whistling instruction, and may be kept on all the time. The sensor and the panoramic image device continuously detect whether a living object is close to or exists around the vehicle or not and recognize the living object as the vehicle runs, and the panoramic image function and the sensor are turned off until the vehicle reaches a destination.
In other embodiments, the sensor and 360-degree panoramic image function for determining and identifying living objects may also be turned on in response to a user activating the vehicle, turned off after the vehicle has performed a blast, or alternatively may remain on until the vehicle reaches a destination.
Referring to fig. 1, in step S120, after the in-vehicle system completes the operation determination of whether the first whistle needs to be executed, the in-vehicle system controls the horn of the vehicle to execute the first whistle with a first volume value lower than the standard volume as a result of the determination that the living object exists within the preset distance range in front of the vehicle and the current vehicle speed is less than the first speed threshold.
In the present invention, the first blast is different from the ordinary blast. The first whistle is warning whistle sent by the vehicle for the first life object in front of the vehicle. In some embodiments of the present invention, after the vehicle detects the presence of a pedestrian within the preset distance range in front through the sensor and identifies the identity of the pedestrian within the preset distance range in front through the image recognition function, the pedestrian in front is marked as pedestrian a. If the vehicle-mounted system judges that one whistle is the first whistle after responding to the vehicle-mounted system to identify the pedestrian A, the whistle sent by the vehicle for the pedestrian A is the first whistle. The general whistle is a warning whistle sent by the vehicle aiming at other obstacles except pedestrians, such as the vehicle and the like.
In some embodiments of the invention, the first volume value is set to 50% of the standard volume. The standard volume of a normal car ranges from 105 db to 118 db, so the first volume value ranges from about 50 db to about 60 db. The first volume range is equivalent to the volume of the human body during normal voice communication. When it is judged that there is a pedestrian in front of the vehicle, the ear of the pedestrian in front is exposed to the whistle of the horn of the vehicle directly at a short distance. The purpose of vehicle is that warning the place ahead pedestrian dodges, and under this kind of condition, car machine system can guarantee to whistle when warning volume security, compromises the travelling comfort of whistle volume to the naked ear of pedestrian. The purpose of warning pedestrians in a close distance ahead can be achieved by executing whistle with the volume as 50% of the standard volume, and meanwhile, the fact that the pedestrians are scared and are disturbed by noise with large volume can be avoided.
However, if the purpose of the vehicle is to warn other vehicles ahead to avoid, the vehicle-mounted system still controls the vehicle horn to execute the whistle operation in the standard sound volume range of about 105-118 decibels. Since the human ear is not closely exposed directly to the whistle sound of the horn of the vehicle if the whistle is performed at the first sound volume lower than about half the standard sound volume in the case where other vehicles occupy the road, because the opposite vehicle is inside the vehicle. Therefore, in this case, if the car machine performs whistle with the first volume, the car owner in the front car cannot hear the whistle warning because the whistle volume is too light, and cannot avoid the whistle warning in time, so that traffic accidents may be caused.
The present invention also needs to set a preset distance range, and the preset distance range is not too long. If the preset distance range is set to be too long, the vehicle performs a whistle operation at a lighter first sound volume, and a pedestrian may not hear the whistle sound performed at the first sound volume by the vehicle in the front long preset distance range. In this embodiment, the preset distance range is 2 meters, and the first volume range is about 50 to 60 decibels, so that when the pedestrian is out of the range of 2 meters in front of the vehicle, a whistle sound with the first volume value emitted by the vehicle-mounted device system may not be heard. In this case, for safety, the on-board unit system controls the vehicle horn to perform the whistle operation at a standard sound volume in a sound volume range of about 105 to 118 db.
In addition, in the present embodiment, the first speed threshold may be 20km/h. The control method of the vehicle whistle volume provided by the invention can be implemented only when the vehicle speed is less than the first speed threshold value by 20km/h. That is, the control method provided by the invention is suitable for the process of low-speed running of the vehicle. Since when the vehicle speed is greater than the first speed threshold value by 20km/h, if the control method is used during high-speed driving of the vehicle, a low whistle is used, but the probability of occurrence of a dangerous accident is increased due to too fast vehicle speed and too low whistle warning tone. In this case, the car-on-board system still controls the vehicle horn to perform the whistle operation within the volume range of about 105 to 118 db at the standard volume.
Therefore, the in-vehicle system controls the horn of the vehicle to perform the first whistle only when the environment around the vehicle simultaneously satisfies the above 3 conditions, that is, the living object exists in the preset distance range in front of the vehicle (condition 1) (condition 2), and the current vehicle speed is less than the first speed threshold (condition 3).
Referring next to fig. 2, fig. 2 is a flowchart illustrating a method for controlling a whistling volume of a vehicle according to an embodiment of the present invention. As shown in fig. 2, fig. 2 further includes, on the basis of the steps of the method for controlling the vehicle whistle volume shown in fig. 1, a step S130:
s130: and in response to the fact that the user sends a second whistle instruction within a preset time period after the first whistle, the living objects in the preset distance range in front of the vehicle do not avoid, and the current vehicle speed is smaller than a first speed threshold value, controlling the vehicle horn to execute the second whistle with a second volume value which is higher than the first volume value and lower than a standard volume value.
In one embodiment, the 360 degree panoramic image function and the sensor are turned off after the vehicle has performed the first blast. When the user finds that the pedestrian is in the first whistle after the vehicle performs the first whistle, the pedestrian is preliminarily judged to occupy the road within a preset time period, such as within 3 minutes, and the pedestrian is not timely avoided due to the first low-whistle. At the moment, the user can choose to issue a second whistling instruction, so that the vehicle enters a preparation state of whistling for the second time, and the panoramic image function and the sensor on the vehicle are also in a re-opening state to further judge the identity of the pedestrian.
Optionally, in another embodiment, the panoramic image function and the sensor are continuously kept on after the vehicle performs the first whistle. In the present embodiment, the panoramic image device and the sensor, which are kept in the on state, continuously photograph and detect the presence or approach of a pedestrian in the vicinity of the vehicle during the driving of the vehicle. When the user finds that the pedestrian is not avoided when occupying the road within a preset time period, such as within 3 minutes, after the vehicle finishes the first whistle, the pedestrian is preliminarily judged. At this time, the user may choose to give a second blast command.
The vehicle-mounted machine system judges whether to execute secondary whistling by receiving the pedestrian avoiding condition within the preset distance range sent by the panoramic image equipment and the sensor and combining the speed of the vehicle.
When the vehicle-mounted device system judges that the vehicle-mounted device system is obtained, the user sends a second whistle instruction within the preset time period after the first whistle, and a pedestrian exists in front of the vehicle within the preset distance range and is an object warned by the first whistle. This means that after the vehicle horn performs the first blast to the pedestrian ahead, the pedestrian still does not avoid in time, so this time it is necessary for the vehicle horn to perform a blast volume that is higher than the first volume of the first blast to alert the pedestrian.
Specifically, in one embodiment, the vehicle-mounted system performs face recognition on a pedestrian occupying the road in front of the vehicle through an image recognition function, and makes a corresponding mark. And then comparing the identity of the pedestrian identified before and after the second whistling instruction with the identity of the pedestrian identified before the first whistling instruction, and if the pedestrian identified before and after the second whistling instruction is judged to be the pedestrian identified before the first whistling instruction, executing the second whistling by the vehicle in response to the whistling instruction sent by the user before.
For example, while the vehicle is traveling at a speed of less than 20km/h, the vehicle determines, by the infrared sensor, that a pedestrian is present within a range of 2 meters in front of the vehicle. The vehicle-mounted system carries out face recognition on the panoramic image including the pedestrian according to the panoramic image shot by the camera outside the vehicle, and the pedestrian is recognized and marked as a pedestrian A. The vehicle controls the vehicle horn to perform a first whistle operation at this time. However, after the vehicle first whistle for 3 minutes, the user finds that the pedestrian is still not giving way, and then the second whistle command is issued.
The vehicle-mounted system recognizes the pedestrian within 2 meters ahead at the next time and the pedestrian A occupying the road ahead for the first time before 3 minutes as the same person through the face recognition function. In order to further warn the opponent, the car machine system controls the car horn to execute a second whistle at a second sound volume higher than the first sound volume but lower than the standard sound volume.
The reason why the volume is higher than the first volume is that the car machine system judges that the pedestrian still serves as the object of the first whistle, which indicates that the pedestrian does not avoid when the vehicle whistles the pedestrian for the first time and still occupies the road in front of the vehicle. Whatever the reason, for example, the pedestrian hears the first whistle of the vehicle but does not timely or actively avoid, or the pedestrian does not hear the first whistle of the vehicle so that the pedestrian does not timely avoid, the final result is that the first whistle executed by the vehicle does not have the effect of timely warning and reminding the pedestrian. Therefore, for the warning effect of the vehicle whistle, the second sound volume of the second whistle is higher than the first sound volume of the second whistle. However, since the target of the whistle warning of the vehicle is only a pedestrian, the second sound volume of the second whistle is still lower than the standard sound volume of the automobile in order to protect the bare ear of the pedestrian on the front lane, which is directly and closely exposed to the whistle of the vehicle.
Alternatively, in some embodiments, the second volume may be set to 80% of the standard volume, in a volume range of about 85 to 95 decibels. This second volume range is more friendly to bare ears exposed closely directly to the whistle of the vehicle horn than the car standard above 100 db volume. However, because its volume is substantially 85 db upward, at this volume, the person's mind is highly concentrated and stressed.
In the actual driving process of the vehicle, in the case that it is determined that there is a pedestrian occupying the lane ahead, and the pedestrian has been recognized to have occupied the lane before this time, and the vehicle has issued a warning for first whistle previously, if the time difference between the determination and recognition times of the vehicle for the pedestrian twice before and after is long, such as the time interval of half an hour, even if the object for which the pedestrian occupying the lane ahead is recognized for the second time is the same as the object for which the pedestrian occupying the lane for the first time is recognized before, because the time interval of the middle is long, there is a high possibility that neither the pedestrian nor the vehicle is in the original position where the whistle for the first time is. In this case, even if the vehicle recognizes that the pedestrian occupying the lane is the object of the first whistle at the time of the second pedestrian identification, the reason why the second whistle is executed is not because the pedestrian does not make a timely collision at the time of the first whistle. Therefore, in this embodiment, the preset time interval between the first time of the whistle operation and the second time of the whistle instruction is not set too long, so that the aim of the whistle operation is to ensure the second whistle performed by the vehicle, and the pedestrian in front does not timely avoid after the first whistle operation.
Based on the above description, the present invention provides a method for controlling a vehicle whistling volume. By implementing the control method, the invention can identify the life object existing in front in time in the driving process of the automobile and automatically turn down the volume when the automobile whistles, thereby realizing the warning of the avoidance of the life object and simultaneously avoiding the accident caused by the damage of ears due to the large volume or the frightening.

It can be read and written at any time (except for refreshing), and is fast, usually used as a temporary data storage medium for an operating system or other programs in operation, and the stored data will be lost when power is off. Cache memory (Cache) 305 is a level one memory existing between main memory and processor 302, and has a relatively small capacity but much higher speed than main memory, close to the speed of processor 302.
It should be noted that, in the case where the control apparatus 300 for vehicle blast volume includes a plurality of memories 701 and a plurality of processors 302, a distributed structure may be provided between the plurality of memories 301 and between the plurality of processors 302. For example, the control method for the vehicle whistle volume may include a memory 301 and a processor 302 respectively located at the local end and the background cloud end, and the local end and the background cloud end jointly implement the control method for the vehicle whistle volume. Furthermore, in the embodiment adopting the distributed structure, each step may adjust a specific execution terminal according to the actual situation, and the specific implementation scheme of each step in a specific terminal should not unduly limit the scope of the present invention.
