The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.
Referring to fig. 1, a schematic flow chart of a warning sound control method provided in an embodiment of the present application may specifically include:
s110, acquiring the distance between the new energy vehicle and the pedestrian;
specifically, the new energy vehicle includes a pure electric vehicle and a hybrid vehicle, and power of the new energy vehicle is provided by a motor during low-speed running. During the running process of the motor, the engine roaring sound of the traditional fuel vehicle is avoided. In the process of low-speed driving of the vehicle, pedestrians in front cannot perceive the coming vehicle in the rear, so that the pedestrians cannot avoid the vehicle in time, and traffic jam or traffic accidents are caused.
The method comprises the steps of firstly obtaining the distance between the new energy vehicle and the pedestrian, wherein the distance can be obtained through image data obtained through a camera for identification, or through data obtained through a radar sensor for identification, or based on the result of fusion of two kinds of data or multiple kinds of data. It is understood that the distance measurement can be performed by the warning tone control device itself, or can be obtained by measuring the distance by other devices of the vehicle.
And S120, under the condition that the distance is smaller than the preset distance, starting the warning sound, wherein the warning sound is obtained based on an audio sample when the fuel vehicle runs.
Specifically, a developer can set a preset distance before the vehicle leaves a factory, and under the condition that the distance is smaller than the preset distance, a warning sound is started to remind pedestrians to avoid the coming vehicle.
It should be noted that most of the existing new energy vehicles adopt a buzzer to emit buzzing-like sounds to remind pedestrians, and the pedestrians can observe the mirror image at the rear after hearing the buzzing sounds and can avoid the vehicles after seeing the vehicles. Although the method can achieve the purpose of reminding the pedestrians, the process of hearing the voice and then observing the voice again brings burden to the pedestrians, the time for the pedestrians to identify the vehicles is prolonged, and the traffic jam condition is easily aggravated.
In the method provided by the scheme, the warning sound is obtained based on the audio sample when the fuel vehicle runs. The running sound of the traditional fuel vehicle is recorded and used as the warning sound. And under the condition that the distance between the pedestrian and the new energy vehicle is smaller than the preset distance, starting the warning sound. When the pedestrian hears the warning sound, because the sound of warning sound is the roaring sound of vehicle, the pedestrian need not to look around back, just can discern that the rear has the vehicle to drive towards oneself to naturally dodge. The warning sound made by the audio sample of the traditional fuel vehicle is used for quickening the response time of the pedestrian for identifying the vehicle, and the pedestrian can rapidly avoid the vehicle, so that the driving safety is improved, and the possibility of traffic jam is reduced.
In conclusion, the embodiment of this application is through the distance that obtains vehicle and pedestrian, when the distance is less than preset distance, reminds the pedestrian through the warning sound that opens the audio sample that obtains when moving with fuel vehicle, and the pedestrian need not to look around again alright discernment come the car in the rear, has reduced the reaction time of pedestrian discernment vehicle, and the pedestrian can dodge the vehicle fast to the security of traveling has been increased, has reduced the possibility that the traffic jams.
In some examples, the warning tone is obtained based on an audio sample of the fuel vehicle during operation, and includes:
the warning tone is obtained based on the audio of the portion of the audio sample sensitive to the pedestrian when the fuel vehicle is running.
Specifically, the audio samples generated during the operation of the fuel vehicle are generated based on the working superposition of various components of the vehicle, and the audio samples have audio frequencies in various frequency ranges and also have large-volume-intensity jitter. Through filtering the audio samples, select pedestrian's sensitive part audio frequency as warning sound, not only can promote the effect of pedestrian's discernment warning sound, also can make the operating frequency range of the part that sends out warning sound reduce greatly simultaneously to reduce warning sound and send out the manufacturing cost of device.
To sum up, through filtering the audio sample, select pedestrian's sensitive part audio frequency as warning sound, not only can promote the effect of pedestrian discernment warning sound, also can make the operating frequency range who sends the part of warning sound reduce greatly simultaneously to reduce warning sound and send the manufacturing cost of device.
In some examples, the frequency range of the portion of audio to which the pedestrian is sensitive is 1000Hz to 3000 Hz.
Specifically, scientific research shows that the sensitive frequency range of human ears to vehicles is 1000 Hz-3000 Hz, and pedestrians can well receive information provided by warning sound by screening 1000 Hz-3000 Hz audio composition warning sound in audio samples in fuel vehicles. Meanwhile, the audio frequency range of the insensitive part of the human body is eliminated, so that the working frequency range of the part which gives out the warning sound is greatly reduced, and the manufacturing cost of the warning sound giving device is reduced.
In conclusion, the frequency range of 1000 Hz-3000 Hz is sensitive to human body, and the pedestrian can well receive the information provided by the warning sound. Meanwhile, the audio frequency range of the insensitive part of the human body is eliminated, so that the working frequency range of the part which gives out the warning sound is greatly reduced, and the manufacturing cost of the warning sound giving device is reduced.
In some examples, the warning tone is obtained based on an audio sample of the fuel vehicle during operation, and includes:
the warning sound is obtained based on a comfortable partial audio frequency of a pedestrian in an audio frequency sample when the fuel vehicle runs, wherein the comfortable partial audio frequency is the audio frequency of which the volume is within a preset interval.
Specifically, in the audio sample during the operation of the fuel vehicle, there is a component having a large sound volume fluctuation range. And an audio sample with the volume within a preset interval is intercepted to serve as warning sound, so that the uncomfortable feeling of pedestrians caused by large volume jump can be avoided.
To sum up, through the audio frequency in the interval of predetermineeing in the screening audio sample as warning sound, can get rid of the great audio frequency of volume beat, from reducing warning sound to pedestrian's uncomfortable sense.
In some examples, the method further comprises:
acquiring the speed of the new energy vehicle;
and adjusting the volume of the warning sound based on the vehicle speed.
Specifically, the speed of the new energy vehicle is obtained through a speed measuring device of the vehicle, and the volume of the warning sound is controlled according to the change of the speed of the vehicle. For example: the volume of the warning sound is enhanced along with the increase of the vehicle speed, the reaction time length left for the pedestrian is reduced along with the increase of the vehicle speed, and the warning sound can be heard at a position far away from the pedestrian by the vehicle through the method of increasing the volume along with the increase of the vehicle speed, so that more reaction time is left for the pedestrian, and the driving safety of the vehicle is improved.
In summary, by acquiring the vehicle speed of the vehicle and adjusting the volume of the warning sound according to the change of the vehicle speed, the volume of the warning sound can be appropriately increased or decreased for different vehicle speeds, so that the time for the pedestrian to identify the vehicle is reasonably controlled, and the driving safety of the vehicle is improved.
In some examples, the adjusting the volume of the warning sound based on the vehicle speed includes:
when the vehicle speed is lower than a preset speed, the volume is increased along with the increase of the vehicle speed;
and when the vehicle speed is higher than the preset speed, the volume is reduced along with the increase of the vehicle speed.
Specifically, by setting the preset speed, the volume of the vehicle increases as the vehicle speed increases when the preset speed is lower, and the volume decreases as the vehicle speed increases when the vehicle speed is higher than the preset speed. According to the historical data of vehicle running, when the vehicle meets the pedestrian, the running speed of the vehicle has an upper limit, the upper limit of the speed is taken as a preset speed, under the condition that the speed is lower than the preset speed, the pedestrian is considered to be in front of the vehicle at the moment, and the reaction time left for the pedestrian is shorter along with the increase of the speed. At the moment, the larger the vehicle running speed is, the larger the volume of the warning sound is, so that the warning sound can be heard by the vehicle at a position far away from the pedestrian, more reaction time is left for the pedestrian, and the running safety of the vehicle is improved. And under the condition that the vehicle is higher than the preset speed, judging that no pedestrian appears near the vehicle or the vehicle is far away from the pedestrian at the moment, gradually reducing the volume of the warning sound along with the increase of the speed, and closing the warning sound until the speed reaches a certain speed.
In conclusion, through rationally setting up preset speed to through the real-time speed of a vehicle and preset the speed of a vehicle comparison, when the speed of vehicle was less than preset speed, judge near vehicle this moment and have the pedestrian, along with vehicle speed promotes, increase the volume of warning sound, thereby increase the distance that the pedestrian can discern the warning sound, reach the purpose that promotes vehicle driving safety nature. When the vehicle speed is higher than the preset speed, judging that no pedestrian exists near the vehicle or the vehicle is far away from the pedestrian at the moment, and controlling the volume of the warning sound to be reduced along with the increase of the vehicle speed until the volume is 0. By the method provided by the embodiment of the application, the position states of the vehicle and the pedestrian can be well identified, so that a warning sound control scheme with pertinence is formulated.
In some examples, the method further comprises:
and under the condition that the headlamp of the new energy vehicle is turned on, turning off the warning sound.
Specifically, in the running process of the vehicle, the situation that the vehicle headlights are turned on is obtained, the vehicle is judged to run at night under the situation that the vehicle headlights are turned on, and the lights can well remind pedestrians that the vehicle runs. Under the condition, the warning sound is turned off, so that the function redundancy caused by full reminding is avoided, and meanwhile, the night warning sound can be prevented from disturbing residents.
Furthermore, many drivers often adopt the mode of frequently switching on and off the high beam to remind pedestrians or vehicles in daytime, and when monitoring that the headlights are switched on, the warning sound is switched off, so that a reminding scheme with more variability can be formed, and a better reminding effect can be achieved for the pedestrians or the vehicles.
In summary, according to the embodiment of the application, the prompt tone is turned off by detecting the turning-on state of the headlight of the vehicle under the condition that the headlight is turned on, so that the phenomenon that the prompt tone disturbs residents at night can be avoided; meanwhile, a changeable reminding mode can be formed by frequently switching on and off the high beam in the daytime, and a better reminding effect can be achieved for pedestrians or vehicles.
