Detailed Description
The technical scheme of the embodiment of the application is suitable for the application scene of warning between different vehicles, and by adopting the technical scheme of the embodiment of the application, abnormal warning information can be timely transmitted to surrounding vehicles when the vehicles are abnormal, and the driving safety and experience of a driver can be improved.
The conventional vehicles interact with each other in the following way, so that a driver of the abnormal vehicle transmits a danger signal to surrounding vehicles.
The first interactive mode is to use light to carry out interaction of abnormal warning information. The lights are mainly a front light and a rear light. The general front lamp is used for warning a front vehicle, and the front vehicle tries to change lanes or brake to be out of order by oneself so as to remind the front vehicle of accelerating or avoiding; the rear tail lamps, especially the brake lamps, can have different brightness along with different braking force so as to remind the rear vehicle of paying attention; the double-flash is used for reminding the left vehicle, the right vehicle and the rear vehicle that the self has a fault or the self has an emergency.
The second interactive mode is to use whistling to carry out interaction of abnormal warning information. The whistle is suitable for various occasions needing to send out abnormal warning information, and warns surrounding vehicles that the vehicles are abnormal when the vehicles are abnormal.
The third interactive mode is to adopt a warning mark to carry out interaction of abnormal warning information. The warning signs are mainly triangular plates, and when the vehicles are anchored on the road, the warning signs can be placed according to traffic rules to remind surrounding vehicles of paying attention.
In the above conventional abnormal warning information interaction modes between vehicles, when a driver of an abnormal vehicle wants to transmit a dangerous signal to surrounding vehicles, the driver needs to pass through light, whistle, warning signs and other modes, however, these conventional interaction modes are often seriously affected by factors such as long communication distance, unobvious light, whistle or warning signs, severe weather and the like, so that the driver of the surrounding vehicles cannot find abnormal warning information sent by the abnormal vehicle in time, and serious traffic accidents are caused.
Therefore, the conventional abnormal warning information interaction mode among vehicles has the problems of poor safety, high efficiency and convenience, so that when the vehicles are abnormal, abnormal warning information cannot be timely transmitted to surrounding vehicles, and the driving safety and experience of drivers are poor.
In order to solve the problem, according to the embodiment of the application, after the warning information is obtained, whether the vehicle alarm is triggered is determined according to the warning information, and when the vehicle alarm is determined to be triggered, the warning signal corresponding to the warning information is sent to the surrounding vehicles of the vehicle, so that the abnormal warning information can be timely transmitted to the surrounding vehicles when the vehicle is abnormal, and the driving safety and experience of a driver can be improved.
The implementation environment provided by the embodiments of the present application is illustrated in more detail below with reference to fig. 1.
As shown in fig. 1, the implementation environment includes a first vehicle 110 and a second vehicle 120. The first vehicle 110 is provided with a microphone 111, a speaker 112, a car radio 113, and a signal processing system 114. The second vehicle 120 is provided with a microphone 121, a speaker 122, a car radio 123, and a signal processing system 124.
The signal processing system 114 and the signal processing system 124 may be formed by a DSP chip or an MCU chip, which is not particularly limited in the embodiment of the present application as long as it has a data processing function.
When an abnormality occurs in the first vehicle 110, the microphone 111 acquires a voice signal uttered by a person in the first vehicle 110 and transmits the voice signal to the signal processing system 114. The signal processing system 114 performs voice recognition processing on the voice signal to obtain warning information, determines whether to trigger the first vehicle 110 to alarm according to the warning information, sends an alarm signal corresponding to the warning information to the vehicle-mounted radio station 113 when determining that the first vehicle 110 is triggered to alarm, and the vehicle-mounted radio station 113 transmits electromagnetic waves corresponding to the alarm signal through a vehicle-mounted antenna. The second vehicle 120 is a vehicle that normally runs around the first vehicle 110 with an abnormality, the vehicle-mounted radio station 123 receives electromagnetic waves corresponding to the alarm signal through the vehicle-mounted antenna and sends the alarm signal to the signal processing system 124, the signal processing system 124 determines whether to trigger the second vehicle 120 to alarm according to the alarm signal, and when it is determined that the second vehicle 120 is triggered, alarms are performed in the second vehicle 120 through a preset mode, for example, abnormal warning information is broadcasted for a user in the second vehicle 120 through the speaker 122.
For the first vehicle 110, the vehicle-mounted radio station 113 may also receive electromagnetic waves corresponding to alarm signals sent by other nearby abnormal vehicles through the vehicle-mounted antenna, and send the alarm signals to the signal processing system 114, the signal processing system 114 determines whether to trigger the first vehicle 110 to alarm according to the alarm signals corresponding to the warning information, and when determining that the first vehicle 110 is triggered to alarm, alarms are performed in the first vehicle 110 through a preset manner, for example, abnormal warning information is broadcast to a user in the first vehicle 110 through the speaker 112.
When an abnormality also occurs in the second vehicle 120, the microphone 121 may also acquire a voice signal uttered by a person in the second vehicle 120 and transmit the voice signal to the signal processing system 124. The signal processing system 124 performs voice recognition processing on the voice signal to obtain warning information, determines whether to trigger other abnormal vehicles around to give an alarm according to the warning information, and sends an alarm signal corresponding to the warning information to the vehicle-mounted radio station 123 when determining that other abnormal vehicles around are triggered to give an alarm, and the vehicle-mounted radio station 123 transmits electromagnetic waves corresponding to the alarm signal through a vehicle-mounted antenna.
That is to say, the signal processing system 114 or the signal processing system 124 can process the voice signal and the warning signal accordingly, so that the first vehicle 110 or the second vehicle 120 can not only trigger an alarm in time and actively when the vehicle is abnormal, but also receive abnormal warning information sent by the abnormal vehicle in time and actively when the vehicle is running normally, thereby improving the driving safety and experience of the driver.
The implementation environment provided by the embodiments of the present application is illustrated in detail above with reference to fig. 1. The vehicle warning method according to the embodiment of the present application will be described in detail with reference to fig. 2 to 9.
Fig. 2 is a schematic flow chart of a vehicle warning method according to an embodiment of the present application. For example, the method may be performed by a server or other type of electronic device having data processing functionality where the signal processing system 114 in the first vehicle 110 or the signal processing system 124 in the second vehicle 120 is located, as mentioned in fig. 1. As shown in fig. 2, the method includes the following steps.
In step S210, warning information is acquired.
In one embodiment, the warning message is a voice warning message converted from a voice signal generated by a person in the vehicle. In one embodiment, a voice signal sent by a person in the vehicle and acquired by a microphone on the vehicle is received, and voice recognition processing is performed on the voice signal to obtain warning information.
Typically, the microphone may be a microphone, which may be used for the purpose of acquiring speech signals. However, in order to achieve voice zoning in the vehicle and suppress noise interference in the vehicle, the microphone may be a microphone array, i.e. a plurality of microphones. A microphone array is a rectangular array of multiple microphones (e.g., four microphones), which can be considered as a sensor device for audio acquisition.
The voice partition is that each microphone judges the position of the sound source and the corresponding personnel information according to the energy detection result and the awakening result of the acquired voice signal. For example, the sound source may be located in a main driving area (i.e., a left front area), a sub driving area (i.e., a right front area), a main driving rear area (i.e., a left rear area) or a sub driving rear area (i.e., a right rear area), and the corresponding person information refers to authority information of the location, i.e., driver authority or vehicle occupant authority.
The voice signal directly acquired by the microphone is an analog signal, and the voice signal is converted through the A/D conversion module to obtain a converted voice signal which is a digital signal, so that the converted voice signal can be subjected to voice recognition processing subsequently. The converted speech signal may also be subjected to noise reduction processing.
The converted voice signal is subjected to voice recognition processing in the following manner. Firstly, voice recognition, semantic understanding, result analysis and result matching are sequentially carried out on the converted voice signals. The semantic result corresponding to the converted voice signal can be obtained by sequentially carrying out voice recognition and semantic understanding on the converted voice signal; then, analyzing the semantic result to obtain a wake-up word corresponding to the converted voice signal; and finally, obtaining warning information by matching the results of the awakening words corresponding to the converted voice signals, namely searching all the awakening words to determine whether the awakening words corresponding to the converted voice signals exist or not, if so, successfully matching, outputting the warning information, if not, unsuccessfully matching, returning an error prompt, and then carrying out voice recognition processing of the steps corresponding to the converted voice signals again.
For example, if a person in the vehicle says "my brake seems to be out of order and needs to notify the rear vehicle of careful driving", the semantic result corresponding to the converted voice signal is "notify the rear vehicle of the fact that the vehicle is out of order" and the awakening word corresponding to the converted voice signal is "out of order".
The voice recognition and semantic understanding can adopt cloud processing, and the result analysis and result matching can adopt local processing, but the embodiment of the application is not particularly limited to this, and the voice recognition, semantic understanding, result analysis and result matching can adopt cloud processing or local processing. Cloud processing may refer to processing by using a cloud computing service center, and local processing may refer to processing by using an electronic device having a data processing function in a vehicle, which is not specifically limited in this embodiment of the present application.
The warning information may include abnormal warning information of vehicle abnormality, which is used to indicate a warning condition to be transmitted by a person in the vehicle, for example, brake failure information, tire burst information, sudden brake information, vehicle oil leakage information, and lane change information.
In step S220, it is determined whether to trigger a vehicle alarm according to the warning information.
After the warning information is acquired, whether the vehicle alarm is triggered or not can be judged through a preset rule, when the warning information meets the preset rule, the vehicle alarm can be triggered, and when the warning information does not meet the preset rule, the vehicle alarm is not triggered.
However, the preset rule is not specifically limited in the embodiment of the present application, and those skilled in the art may make different selections according to actual requirements.
In step S230, when it is determined that the vehicle alarm is triggered, an alarm signal corresponding to the warning information is transmitted to the vehicle around the vehicle.
The warning signal includes all contents included in the warning information, for example, abnormal warning information of abnormality of the vehicle, authority information of a person in the vehicle, sound source information, warning signal flag information, or target position information.
The surrounding vehicle refers to a vehicle located right in front of, right behind, left in front of, right in front of, left behind, or right behind the vehicle, but the present embodiment does not specifically limit the specific orientation of the surrounding vehicle, and the vehicle may transmit the warning signal to all the surrounding vehicles.
According to the vehicle alarm method, after the alarm information is obtained, whether the vehicle alarm is triggered is determined according to the alarm information, and when the vehicle alarm is determined to be triggered, the alarm signal corresponding to the alarm information is sent to the surrounding vehicles of the vehicle, so that the abnormal alarm information can be timely transmitted to the surrounding vehicles when the vehicle is abnormal, and the driving safety and experience of a driver can be improved.
In an embodiment, the preset rule may be implemented by using the method steps shown in fig. 3.
In step S310, abnormality information of the vehicle is acquired from a sensing module of the vehicle. The sensing module can be a sensing and information acquisition system on the vehicle, and has the main functions of acquiring the sensing information of the vehicle-mounted sensor and automatically analyzing and identifying whether the vehicle has abnormal conditions according to the sensing information. The vehicle-mounted sensor is, for example, a temperature sensor for detecting an engine temperature, a cooling water temperature, and the like, and the sensing information is temperature sensing information for determining whether the vehicle has a risk of spontaneous combustion and ignition; the vehicle-mounted sensor is a pressure sensor for detecting the internal pressure and the oil pressure of the cylinder and the tire pressure of the tire, and the sensing information is pressure sensing information for judging whether the vehicle has the risk of vehicle oil leakage and judging whether the vehicle has the risk of tire burst; the vehicle-mounted sensor is, for example, a rotation speed sensor for detecting the engine rotation speed, the vehicle speed, the acceleration and the like, and the sensing information is speed sensing information for determining whether the vehicle runs at an overspeed or a low speed. The embodiment of the present application does not specifically limit the type of the vehicle-mounted sensor.
After the sensing information of the vehicle-mounted sensor is collected, whether the sensing information of the vehicle-mounted sensor is abnormal or not is judged, that is, whether the vehicle has the risks mentioned in the above examples or not is judged. The sensing information collected by each vehicle-mounted sensor corresponds to a preset safety threshold range, and whether the vehicle has the risks mentioned in the examples can be judged by judging whether the sensing information is in the preset safety threshold range. When the sensing information is not within the preset safety threshold value range, determining that the vehicle has one of the risks mentioned in the above example, and determining the sensing information which is not within the preset safety threshold value range as abnormal information.
The in-vehicle sensor may be a position sensor for detecting a vehicle traveling direction, a vehicle position, and the like to determine vehicle condition information such as position information and traveling direction information of the vehicle. Although the vehicle condition information collected by the position sensor cannot be analyzed and recognized whether the vehicle has an abnormal condition, that is, the vehicle condition information does not have a specific preset safety threshold range, the vehicle condition information of the vehicle can also be obtained from a sensing module of the vehicle, so as to accurately locate a target position where a person in the vehicle transmits abnormal warning information, and a distance between the position of the vehicle and the target position, so as to avoid influencing other unrelated vehicles (for example, oncoming vehicles), thereby being beneficial to improving the accuracy and reliability of the warning.
In step S320, it is determined whether the abnormality warning information matches the vehicle abnormality indicated by the abnormality information. The embodiment of the present application does not specifically limit the type of the vehicle abnormality represented by the abnormality information, and each piece of sensing information may correspond to one vehicle abnormality, for example, the pressure sensing information corresponds to a vehicle abnormal flameout or a tire burst. For example, the preset safety threshold value range of the pressure sensing information is between 2.3 and 2.5 for the tire pressure of the tire, and if the pressure sensing information detected by the pressure sensor is not between 2.3 and 2.5, the vehicle abnormality represented by the abnormality information is tire pressure abnormality. The vehicle abnormality indicated by the abnormality information may also be a coolant temperature abnormality, an engine abnormality, or the like.
In step S330, when the abnormality warning information matches the vehicle abnormality indicated by the abnormality information, it is determined that a vehicle alarm is triggered. Since the abnormality warning information is converted from a voice signal emitted from a person in the vehicle, the abnormality warning information is a predicted abnormality of the vehicle. And the vehicle abnormity represented by the abnormal information is the abnormity which really exists in the vehicle, so that the abnormal warning information conveyed by personnel in the vehicle can be determined whether the abnormal warning information really exists or not by comparing the artificially predicted vehicle abnormity with the abnormity which really exists in the vehicle, and unnecessary alarm caused by artificial prediction error is avoided. And when the artificially predicted vehicle abnormality is consistent with the actually existing abnormality of the vehicle, namely the vehicle abnormality represented by the abnormality warning information is consistent with the vehicle abnormality represented by the abnormality information, determining to trigger vehicle alarm.
In another embodiment, the preset rule may also be implemented by using the method steps shown in fig. 4.
The warning information includes, in addition to the above-mentioned information, authority information of the person in the vehicle, the authority information including the driver authority.
In step S410, it is determined whether the authority information of the person in the vehicle is the driver authority. Each person in the vehicle has its own authority information, e.g. the driver's authority or the driver's authority, but only the driver's authority that the driver has can trigger an alarm.
As described in step S210, according to the energy detection result and the wake-up result of the voice signal acquired by each microphone, the position of the sound source and the corresponding personal information can be determined, that is, voice partitioning is implemented. Thus, the warning information also includes sound source information indicating where the person in the vehicle is located.
Through the voice partition, the position of a person in the vehicle sending the voice signal and the corresponding authority information can be determined. For example, the location of the person in the vehicle that uttered the voice signal is located in the main driving area (i.e., the left front area), and the person in the vehicle has the driver authority; the position of the person in the vehicle from which the voice signal is emitted is located in a passenger driving region (i.e., a right front region), a main driving rear region (i.e., a left rear region), or a passenger driving rear region (i.e., a right rear region), and the person in the vehicle has the occupant authority.
Therefore, the position of the person in the vehicle can be determined based on the sound source information, and the authority information of the person in the vehicle can be determined as the driver authority when the position of the person in the vehicle is the driver position of the vehicle.
In step S420, when the authority information of the person in the vehicle is the driver authority, it is determined that the vehicle alarm is triggered. In order to avoid that people except a driver trigger the alarm by mistake, the vehicle alarm can be determined to be triggered only when the authority information of the people in the vehicle is the authority of the driver.
In another embodiment, the alert message includes, in addition to the above-mentioned information, a warning signal flag message indicating whether to activate an alarm. Therefore, the preset rule can also be realized by adopting a method that when the early warning signal mark information meets the condition of starting the warning, the vehicle warning is determined to be triggered.
The condition for starting the alarm may be that the early warning signal flag is 1, that is, when the early warning signal flag is 1, the condition for starting the alarm is satisfied, and the vehicle alarm is determined to be triggered, and when the early warning signal flag is 0, the condition for starting the alarm is not satisfied, and the vehicle alarm is not triggered. However, the embodiment of the present application does not specifically limit the start alarm condition.
When the warning information is not acquired, the warning signal mark is empty (namely 0), whether the vehicle alarm is triggered is not judged, and the vehicle does not consume energy; when the warning information is acquired, the warning signal flag is set (namely 1), whether a vehicle alarm is triggered or not is judged, and the vehicle is awakened and is in a monitoring control command state.
Therefore, the warning mode can be started when the vehicle needs to give an alarm through the early warning signal mark information, and the vehicle is in the non-warning mode when the vehicle does not need to give an alarm, so that the whole memory consumption of the vehicle is saved.
In addition to the above-mentioned three methods to implement the preset rule, the embodiment of the present application may implement the preset rule by combining at least two of the above three methods together. That is, when the early warning signal mark information meets the condition of starting the warning and when the vehicle abnormality represented by the abnormal warning information and the abnormal information is consistent, the vehicle warning is triggered; or when the early warning signal mark information meets the condition of starting the warning and the authority information of personnel in the vehicle is the authority of the driver, triggering the vehicle to warn; or when the authority information of the personnel in the vehicle is the driver authority and the vehicle represented by the abnormal warning information is abnormal and consistent with the vehicle represented by the abnormal information, triggering the vehicle to alarm; or when the early warning signal mark information meets the condition of starting warning, the vehicle represented by the abnormal warning information and the abnormal information is abnormal and consistent, and when the authority information of personnel in the vehicle is the authority of the driver, the vehicle warning is triggered. The combination of the above methods can improve the accuracy of alarm.
In one embodiment, the warning information includes, in addition to the above-mentioned information, target position information for indicating a target position at which the person in the vehicle intends to convey the abnormality warning information, the target position information being an orientation at which the person in the vehicle intends to convey the abnormality warning information, typically being directly in front, directly behind, left-front, right-front, left-rear, or right-rear.
For example, when the abnormality warning information is brake failure information, the vehicle abnormality indicated by the abnormality warning information is brake failure, and therefore a person in the vehicle wants to transmit the brake failure information to a preceding vehicle (e.g., a vehicle right ahead, a vehicle left ahead, and a vehicle right ahead) to warn the preceding vehicle away from the vehicle, thereby avoiding a collision between the two vehicles. For another example, when the abnormality warning information is sudden braking information, and the vehicle abnormality indicated by the abnormality warning information is sudden braking, a person in the vehicle wants to transmit the sudden braking information to a rear vehicle (most importantly, a vehicle right behind) to warn the rear vehicle of deceleration traveling, thereby avoiding collision between the two vehicles.
In an embodiment, after the warning signal corresponding to the warning information is sent to the surrounding vehicle of the vehicle, a warning may be given in a preset manner in the surrounding vehicle, which includes at least one of the following manners: the alarm is carried out through the sound effect system of the surrounding vehicles and the alarm is carried out through the display system of the surrounding vehicles.
In addition to the warning of the surrounding vehicle in a predetermined manner, the vehicle may also automatically turn on the headlights or the lights of the vehicle after it is determined that the vehicle warning is triggered, and emit a specific warning sound, such as a warning sound of "beep" or a specific warning sound of "brake failure of the vehicle ahead, attention to avoidance" through an external horn of the vehicle.
The embodiment of the application can send the alarm signal in the following mode, for example, the alarm signal corresponding to the warning information is sent to a vehicle-mounted radio station of a vehicle, so that the alarm signal corresponding to the warning information is sent to surrounding vehicles through the vehicle-mounted radio station of the vehicle.
The alarm signal is firstly encoded through an encoding module to obtain an encoded alarm signal, the encoded alarm signal is a digital signal, and the encoded alarm signal is converted through a D/A conversion module to obtain a converted alarm signal which is an analog signal and is used as an analog input signal of a vehicle-mounted radio station of the vehicle. The vehicle-mounted radio station of the vehicle comprises an FM modulation function, and after the warning information contained in the converted alarm signal is modulated, the modulated alarm signal (namely, the FM modulation signal) is transmitted through the vehicle-mounted antenna, so that surrounding vehicles can obtain the modulated alarm signal from the vehicle-mounted radio station of the vehicle through the vehicle-mounted radio station.
The coding module can carry out information compression processing and anti-interference coding to the alarm signal. The coding mode of the coding module comprises audio coding or text coding. After the audio coding is carried out, the modulated alarm signal is an alarm audio signal and is used for broadcasting the abnormal warning information through a loudspeaker; after text coding, the modulated alarm signal is an alarm text signal and is used for displaying the abnormal warning information through a display.
The abnormal information may include vehicle speed information, and therefore, the power of the warning signal after transmission modulation of the vehicle-mounted radio station can be adjusted through the speed information. The faster the vehicle speed is, the larger the gain of the power amplifier of the vehicle-mounted station is, and the higher the urgency level of the abnormality warning information is.
There are two methods for FM modulation of the vehicle radio, including direct and indirect frequency modulation. The direct frequency modulation method is based on the principle of modulating the frequency of a voltage control oscillator, and has the advantages of simple circuit and capability of obtaining larger frequency deviation; the indirect frequency modulation method is also called Armstrong method, the principle is that the phase modulation is controlled by the result of modulating voltage integration, and a broadband frequency modulation signal is obtained after n times of frequency multiplication. In order to simplify the circuit, the direct frequency modulation method is adopted in the embodiment of the present application, but the embodiment of the present application is not particularly limited to this, and those skilled in the art may make different selections according to actual needs.
The vehicle radio station adopts Frequency Modulation (FM), and the advantage of FM is that anti-noise ability is strong, power utilization is high, is widely applied to the occasion that high quality or channel noise are big, for example: frequency modulation broadcasting, satellite communication, mobile communication, and the like. The frequency modulation technology is adopted because the vehicle-mounted radio station of each vehicle widely has FM modulation and demodulation functions, and the existing FM communication system can be utilized, so that extra cost is not increased.
Besides the above-mentioned sending of the alarm signal by means of the vehicle-mounted radio station, the alarm signal may also be sent by means of a server. For example, an alarm signal corresponding to the warning information is sent to the server, so that the alarm signal corresponding to the warning information is sent to surrounding vehicles through the server.
In one embodiment, the alarm signal is encoded by the encoding module to obtain an encoded alarm signal, and the encoded alarm signal is sent to the server.
The server may be a local car management server. In an urban area covered by the local area network, each vehicle is connected to a local vehicle management server through the local area network, so that the coded alarm signal is sent to the local vehicle management server, and the coded alarm signal is sent to any one of the vehicles around through the internet by the vehicle management server, so that abnormal warning information can be timely transmitted to the vehicles around, and the driving safety and experience of a driver can be improved.
However, the specific type of the server is not limited in the embodiment of the present application, and the server may also be a server in the cloud.
The embodiment of the present application does not specifically limit the manner of sending the alarm signal, and the alarm signal may also be sent by using other communication technologies such as bluetooth. For example, vehicles interact with each other via bluetooth technology.
In another embodiment of the present application, in order to improve the timeliness, accuracy and reliability of the alarm, after the abnormality information of the vehicle is obtained from the sensing module of the vehicle, the abnormality information of the vehicle as described in the embodiment of fig. 3 may be sent to the server, so that the surrounding vehicle can obtain the abnormality information of the vehicle from the server.
When the server is a local automobile management server, each vehicle sends the abnormal information of the vehicle as described in the embodiment of fig. 3 to the local automobile management server, so that the local automobile management server has the abnormal information of each vehicle within a certain local range, and when one vehicle is abnormal, other vehicles can know the abnormality of the vehicle through the local automobile management server, so that the alarm can be given timely, accurately and reliably.
In another embodiment of the present application, in order to improve the accuracy and reliability of the alarm, vehicle condition information such as position information and traveling direction information of the vehicle is acquired from a sensing module of the vehicle, and then the vehicle condition information such as the position information and the traveling direction information of the vehicle is transmitted to a server, so that surrounding vehicles acquire the vehicle condition information of the vehicle from the server.
When the server is a local automobile management server, each automobile sends the automobile condition information of the automobile to the local automobile management server, so that the local automobile management server has the automobile condition information of each automobile within a certain local range, and when one of the automobiles is abnormal, other automobiles can know the automobile condition of the automobile through the local automobile management server, so that the alarm can be accurately and reliably given.
However, the present embodiment is not limited to the specific type of the vehicle condition information, and may be position information of the vehicle, traveling direction information of the vehicle, vehicle speed information of the vehicle, or the like.
In another embodiment of the present application, a warning signal is sent to a driver assistance system of a vehicle to assist a driver within the vehicle in driving safely. The driving assistance system comprises a lane keeping assistance system, an automatic parking assistance system, a brake assistance system, a backing assistance system or a driving assistance system. After the assistant driving system receives the alarm signal, the assistant driving system can assist the driver in the vehicle to drive safely according to the abnormal warning information, for example, if the abnormal warning information is brake failure information, the brake assistant system in the assistant driving system can assist the vehicle to brake so as to reduce the vehicle speed and reduce the braking distance.
Fig. 5 is a flowchart illustrating a vehicle warning method according to an embodiment of the present application. For example, the method may be performed by a server or other type of electronic device having data processing functionality where the signal processing system 114 in the first vehicle 110 or the signal processing system 124 in the second vehicle 120 mentioned in fig. 1 is located. As shown in fig. 5, the method includes the following steps.
In step S510, an alarm signal corresponding to warning information transmitted by an abnormal vehicle is received.
As described in the embodiment of step S210, the warning information may include abnormal warning information of an abnormal vehicle, which is used to indicate a warning to be transmitted by a person in the abnormal vehicle, for example, brake failure information, tire burst information, sudden braking information, vehicle oil leakage information, or lane change information, but this embodiment of the present application is not limited thereto specifically, and the abnormal warning information may also include other information as long as the information can be used to indicate a warning to be transmitted by a person in the abnormal vehicle, and for any emergency situation, the person in the abnormal vehicle may transmit the warning to a surrounding vehicle by means of the abnormal warning information.
As described in the embodiment of step S230, the abnormal vehicle may send the warning signal by way of its vehicle-mounted station, and may also send the warning signal by way of the server, so that the vehicle described in this embodiment may correspondingly receive the warning signal by way of its vehicle-mounted station, and may also receive the warning signal by way of the server.
In one embodiment, the abnormal vehicle transmits the modulated alarm signal through the vehicle-mounted antenna, and after receiving the modulated alarm signal through the vehicle-mounted antenna of the vehicle, the modulated alarm signal is sent to a vehicle-mounted radio station of the vehicle. The vehicle-mounted station of the vehicle includes an FM demodulation function therein, and demodulates the modulated alarm signal to obtain a demodulated alarm signal (i.e., an FM demodulated signal).
There are two methods of FM demodulation in the vehicle station, including non-coherent demodulation and coherent demodulation. The incoherent demodulation is to convert the frequency change into amplitude change and then demodulate in an envelope detection mode, and has the advantages of simple circuit; coherent demodulation needs to recover local oscillation signals and is only suitable for narrow-band frequency modulation signals. In order to simplify the circuit, the embodiment of the present application adopts non-coherent demodulation, but the embodiment of the present application is not limited to this specifically, and those skilled in the art may make different selections according to actual needs.
In one embodiment, when the alarm signal is received by the server, the server receives the encoded alarm signal, and thus, the encoded alarm signal is obtained from the server. The server may be a local car management server. In an urban area covered by the local area network, each vehicle is connected to a local automobile management server through the local area network, therefore, after the abnormal vehicle sends the coded alarm signal to the local automobile management server, the automobile management server sends the coded alarm signal to the vehicle through the internet, and therefore the vehicle can timely receive abnormal warning information, and driving safety and experience of a driver can be improved.
The embodiment of the application does not specifically limit the manner of receiving the alarm signal, and the alarm signal can be received through other communication technologies such as bluetooth. For example, vehicles interact with each other via bluetooth technology.
In step S520, whether to trigger a vehicle alarm is determined according to the alarm signal corresponding to the warning information.
In one embodiment, when the alarm signal is received by the vehicle radio station, the demodulated alarm signal is an analog signal, the demodulated alarm signal is converted by the a/D conversion module to obtain a converted alarm signal, which is a digital signal, and the converted alarm signal is decoded by the decoding module to obtain a decoded alarm signal.
In an embodiment, when the alarm signal is received by the server, the encoded alarm signal may be directly decoded by the decoding module to obtain a decoded alarm signal.
Specifically, whether a vehicle alarm is triggered or not can be determined according to the decoded alarm signal, in addition, the decoded alarm signal can be subjected to filtering processing, and whether the vehicle alarm is triggered or not can be determined according to the filtered alarm signal.
The decoding mode of the decoding module can comprise audio decoding and/or text decoding. After the audio decoding is carried out, the decoded alarm signal is an alarm audio signal and is used for broadcasting the abnormal warning information through a loudspeaker; after the text coding is carried out, the decoded alarm signal is an alarm text signal and is used for displaying the abnormal warning information through the display.
After the alarm signal, whether the vehicle alarm is triggered or not can be judged through a preset rule, when the alarm signal meets the preset rule, the vehicle alarm can be triggered, and when the alarm signal does not meet the preset rule, the vehicle alarm is not triggered.
However, the preset rule is not specifically limited in the embodiment of the present application, and those skilled in the art may make different selections according to actual requirements.
In one embodiment, the preset rule may be implemented by using the method steps shown in fig. 6.
In step S610, the relative position information of the vehicle with respect to the abnormal vehicle is acquired. In one embodiment, the relative position information is azimuth information of a position where the vehicle is located relative to a position where the abnormal vehicle is located.
The abnormal vehicle can transmit the vehicle condition information such as the position information and the traveling direction information of the abnormal vehicle to the server, so that the vehicle can acquire the position information and the traveling direction information of the abnormal vehicle from the server, acquire the vehicle condition information, namely the position information and the traveling direction information, of the vehicle from a sensing module (for example, a GPS module) of the vehicle, and acquire the relative position information of the vehicle relative to the abnormal vehicle according to the position information and the traveling direction information of the abnormal vehicle and the position information and the traveling direction information of the vehicle.
For example, the position information of the abnormal vehicle is 120km from the toll station a with high speed of jingjin, and the driving direction information of the abnormal vehicle is from south to north to the toll station a with high speed of jingjin; since the vehicle position information is 115km from the kyazine high-speed toll station a and the vehicle traveling direction information is also 115km from the south to the north to the kyazine high-speed toll station a, the traveling directions of the two are the same, and the vehicle can be located behind the abnormal vehicle by the 120km position from the kyazine high-speed toll station a and the 115km position from the kyazine high-speed toll station a.
The above is only an example of the embodiment of the present application, and the embodiment of the present application may further determine the relative position information according to the longitude and latitude information and the driving direction of each vehicle.
In step S620, it is determined whether the relative position information and the target position information coincide. The target position information is included in the warning signal for indicating a target position at which a person in the abnormal vehicle transmits the abnormal warning information. The target position information is a direction in which a person in the abnormal vehicle intends to transmit the abnormal warning information, and is generally a front direction, a rear direction, a front left direction, a front right direction, a rear left direction, or a rear right direction.
In step S630, when the relative position information and the target position information coincide, it is determined that a vehicle alarm is triggered. For example, when the abnormal warning information is sudden braking information, a person in the abnormal vehicle wants to transmit the sudden braking information to the rear vehicle to warn the rear vehicle to get away from the abnormal vehicle, thereby avoiding collision between the two vehicles. Therefore, when the relative position information indicates that the vehicle is located behind the abnormal vehicle, the relative position information is consistent with the target position information, and then the vehicle alarm is determined to be triggered.
Even if the alarm signal corresponding to the warning information is acquired, the warning signal flag contained in the warning information and used for indicating whether to start the alarm is empty (namely 0), and the vehicle consumes no energy; when the relative position information is consistent with the target position information, the early warning signal flag is set (namely 1), the vehicle is awakened, and an alarm can be given in the vehicle in a preset mode.
Therefore, the warning mode can be started when the vehicle meets the requirement and is in the non-warning mode when the vehicle does not meet the requirement through the early warning signal mark information, and therefore the whole memory consumption of the vehicle is saved.
In step S530, when it is determined that the vehicle alarm is triggered, an alarm is performed in the vehicle in a preset manner.
In one embodiment, the audio decoded warning signal is sent to a sound effect system of the vehicle, so that abnormal warning information is broadcasted for users in the vehicle through a loudspeaker on the vehicle. The speaker may be a speaker array, that is, a plurality of speakers, and the number of speakers is not particularly limited in the embodiments of the present application.
The loudspeaker can not only make an alarm prompt tone according to the abnormal warning information, but also can broadcast specific alarm tone by combining a voice recognition module and through a voice synthesis technology.
For example, the abnormal warning message sent by the abnormal vehicle is a brake failure message, and the speaker may send a warning tone "beep" according to the brake failure message. However, the specific type of the warning tone in the embodiment of the present invention is not limited, and different types of warning tones may be generated for different abnormality warning information, for example, a warning tone in which the brake failure information corresponds to "beep" and a warning tone in which the sudden brake information corresponds to "squeak.
For another example, the abnormal warning information sent by the abnormal vehicle is brake failure information, the voice recognition module carries out voice synthesis on the brake failure information by using a voice synthesis technology, and a specific alarm sound is broadcasted to be used as 'brake failure of the front vehicle and attention to avoidance'.
The alarm prompt sound or the specific alarm sound sent by the loudspeaker can create the atmosphere of the alarm prompt for personnel in the vehicle, so that a driver can notice the abnormal vehicle and make avoidance in time.
In addition, the alarm prompt tone and the specific alarm tone sent by the loudspeaker jointly prompt personnel in the vehicle, and the double prompt can enable a driver in the vehicle to timely and accurately understand the alarm condition and make corresponding measures so as to avoid traffic accidents.
The sound effect system may further include an alarm sound effect generation module or an audio amplification module in addition to the above-mentioned speaker.
The alarm sound effect generation module can be generated by a DSP of the vehicle, and is synthesized by sine waves with different frequencies to simulate the alarm sound effects of different abnormal warning information. The specific alarm sound effect can be generated by Dual Tone Multi Frequency (DTMF) technology, which consists of a high Frequency group and a low Frequency group, each of which contains 4 frequencies. A high frequency signal and a low frequency signal are superimposed to form a combined signal which is a DTMF signal representing a digit. The DTMF signal has 16 codes, and the embodiment of the application adopts 16 codes of the DTMF signal, and corresponds to 16 different kinds of abnormal warning information. As shown in fig. 7, which shows a schematic diagram of the generation of different alarm tones by means of DTMF technology.
The input signal of the audio amplification module is an analog signal. And converting the DTMF signal generated by the alarm sound effect generation module through the D/A conversion module to obtain an analog signal required by the audio amplification module.
Since the analog signal is a relatively weak small signal, it is not sufficient to drive the speaker array. Under the general condition, the power requirement of the vehicle-mounted loudspeaker array is different from dozens of watts to hundreds of watts, some low-end vehicle-mounted power amplification systems can provide output power of dozens of watts, and some high-end power amplifiers can improve the output power of hundreds of watts, so that the whole set of loudspeaker system can be driven. Therefore, the audio amplification module is used for amplifying the power of the relatively weak analog signal so as to enable the analog signal to be played through the loudspeaker.
In one embodiment, the text-decoded warning signal is sent to a display system of the vehicle to present the user in the vehicle with exception alert information via a display on the vehicle. The display is a vehicle-mounted display and is used for dynamically displaying the abnormal warning information contained in the alarm signal after the text decoding on a screen of the display. The abnormal warning information contained in the text decoded alarm signal is text information which can be embedded in a navigation map of a display.
In addition, the navigation map can also display the position information or the speed information of the vehicle and the position information or the speed information of an abnormal vehicle, so that a driver can conveniently and accurately judge road conditions in time, measures such as avoidance, detour giving and the like can be taken as soon as possible, and the safety and the smoothness of road traffic are greatly improved.
In another embodiment of the present application, a warning signal is sent to a driver assistance system of a vehicle. After the assistant driving system receives the alarm signal, the assistant driving system can assist the driver in the vehicle to drive safely according to the abnormal warning information. For example, if the abnormal warning information is sudden braking information, the driving assistance system may automatically decide that the vehicle is decelerated to assist the driver to drive more safely.
