A vehicle whistle method and apparatus according to embodiments of the present application will be described in detail with reference to the accompanying drawings.

Fig. 1 is a schematic flow chart of a vehicle whistling method according to an embodiment of the present application. The vehicle whistle method of fig. 1 may be performed by a vehicle controller. As shown in fig. 1, the vehicle whistling method includes:

s101, determining a target vehicle to receive ultrasonic information and a first reminding level for the target vehicle; wherein the ultrasonic information is emitted by an ultrasonic transmitting device mounted on the first vehicle.

It should be noted that, the frequency of the ultrasonic information is greater than the maximum value of the audible frequency range of the human ear, that is, greater than 20000 hz, so that the whistle interaction is performed between the vehicles through the ultrasonic information, and no interference is caused to the personnel outside the vehicles.

Furthermore, an ultrasonic wave transmitting device is mounted on the first vehicle, by means of which ultrasonic wave transmitting device the first vehicle can transmit ultrasonic wave information.

Specifically, the number of target vehicles is at least one; the target vehicle and the first alert level are selected to provide data support for subsequent first vehicle determination of blast direction and blast period.

S102, determining a target sound wave emission period corresponding to the first reminding level according to a first corresponding relation between the preset reminding level and the sound wave emission period.

Specifically, the corresponding relation between the preset reminding level and the sound wave emission period can be a negative correlation relation, namely, the higher the reminding level is, the shorter the sound wave emission period is, and meanwhile, the higher the representative sound wave emission frequency is, so that the emergency degree of an event can be embodied, specifically, the negative linear correlation relation or other negative correlation relations can be set according to scene needs.

And determining a target sound wave emission period corresponding to the first reminding level, so that the first vehicle can emit ultrasonic information in the target sound wave emission period, and the emergency degree of the first vehicle can be reflected through the target sound wave emission period, thereby providing support for judging the emergency degree of the first vehicle through the sound wave emission period of the ultrasonic information for the subsequent target vehicle.

In addition, it should be noted that the reminding level and the whistle event of the vehicle should also have a preset corresponding relationship, so that the driver can determine the first reminding level according to the preset corresponding relationship and the whistle event, so as to avoid the problem caused by wrong selection of the first reminding level by the driver, and the preset corresponding relationship can be one-to-many between the reminding level and the whistle event.

Specifically, as an example, the above-mentioned correspondence between the preset alert level and the sound wave emission period and the preset correspondence may be as shown in the following table:

The number of the reminding levels can be 3, 4, 5 and the like, the corresponding sound wave emission period number is the same as the number of the reminding levels, the table is only one of a plurality of embodiments, the specific number and content of the reminding levels and the sound wave emission periods can be specifically set according to the requirements of actual application scenes and different vehicle functions, and the application does not limit the specific number

S103, determining a target distance between the first vehicle and the target vehicle, and determining target sound wave intensity corresponding to the target distance according to a second corresponding relation between the preset distance and the sound wave intensity.

Specifically, the target distance is a straight line distance excluding the length of the feasible path between the first vehicle and the target vehicle; the target distance may be obtained from a distance detection device mounted on the first vehicle, such as a lidar, a distance sensor, etc.

In addition, the second correspondence between the preset distance and the acoustic wave intensity may be a positive linear correlation, that is, the different distances and the different acoustic wave intensities are in one-to-one correspondence, and the greater the distance, the greater the acoustic wave intensity. Since the first vehicle may be traveling during the blast, the distance between the first vehicle and the target vehicle may change, and the corresponding target sound wave intensity may also need to be changed. For example, when the target distance is reduced, it is indicated that the distance between the first vehicle and the target vehicle is reduced, and if the original target sound wave intensity is still used, the target vehicle may be affected, and at this time, the sound wave intensity is reduced correspondingly, so that the ultrasonic energy received by the target vehicle is ensured to be in a proper and safe range. In addition, the target sound wave intensity corresponding to the target distance is determined, so that the target vehicle can receive the ultrasonic waves emitted by the first vehicle, and meanwhile, the influence on the running of surrounding vehicles caused by the fact that the sound wave intensity of the ultrasonic waves is too high can be avoided.

Specifically, the target sound wave intensity can be calculated by the following formula:

P_t＝P*L_t

wherein, P represents a preset ultrasonic intensity, L _t may represent a target distance at time T, and P _t represents a target acoustic wave intensity at time T. Specifically, as an example, it can be understood that, at a target distance of 1m, the intensity of the ultrasonic wave received by the target vehicle is P, and each time the target distance increases or decreases by 1m, the intensity of the target acoustic wave correspondingly increases or decreases PW/m ²; the preset ultrasonic intensity can be 100W/m ²、200W/m², and can be set according to a specific test result, and the application is not limited to the preset ultrasonic intensity. Since the direction in which the vehicle transmits the ultrasonic information may be any direction, the target distance in the above formula cannot be negative, and the target ultrasonic intensity cannot be negative.

And S104, transmitting first ultrasonic information to the position coordinates of the target vehicle according to the target sound wave transmitting period and the target sound wave intensity.

The first ultrasonic information carries a first reminding grade, an intention corresponding to the first reminding grade is obtained through analysis by an ultrasonic detection device arranged on the target vehicle, and the intention is sent to a sound playing device in the vehicle of the target vehicle for voice playing.

Specifically, the position coordinates of the target vehicles may be determined by a method of establishing a coordinate system, and in addition, in a case where the number of target vehicles is greater than a preset number, the directions in which the first ultrasonic information is transmitted may be determined for the position coordinates of the plurality of target vehicles, respectively, for example, as one example, assuming that the first vehicle is about to change lane to the right, the first vehicle needs to prompt vehicles right in front of, right behind, and thus it may be determined that the directions in which the first ultrasonic information is transmitted by the first vehicle may be right in front of, right behind. The first ultrasonic information is transmitted to the position coordinates of the target vehicle, so that the interference of the ultrasonic information to other vehicles which do not need to receive the whistle information can be reduced.

The first ultrasonic information may also carry a license plate number of the first vehicle, an upcoming vehicle action, and the like.

Specifically, the ultrasonic detection device on the target vehicle can be installed in the vehicle of the target vehicle or outside the vehicle of the target vehicle, and the ultrasonic detection device can comprise an ultrasonic probe, an ultrasonic controller and a transmission device, wherein the ultrasonic probe can receive ultrasonic information, the ultrasonic controller can analyze the received ultrasonic information to obtain the intention represented by the ultrasonic information, and the transmission device can transmit the analyzed information to the in-vehicle sound playing device of the target vehicle.

The target vehicle can control the volume of the voice played in the vehicle by manually rotating, toggling the volume adjusting device, or sliding a volume sliding bar in the screen, and the like.

According to the technical scheme provided by the embodiment of the application, the interference of the whistle to surrounding personnel is avoided by determining the target vehicle to receive the ultrasonic information and the first reminding level aiming at the target vehicle, and data support is provided for the subsequent first vehicle to determine the whistle direction and the whistle period; the target sound wave emission period corresponding to the first reminding level is determined according to the first corresponding relation between the preset reminding level and the sound wave emission period, so that the emergency degree of an event can be reflected, and the target vehicle can be helped to make judgment; by determining the target distance between the first vehicle and the target vehicle and determining the target sound wave intensity corresponding to the target distance according to the second corresponding relation between the preset distance and the sound wave intensity, the target vehicle can be ensured to be capable of receiving the ultrasonic waves emitted by the first vehicle and meanwhile the running of surrounding vehicles cannot be influenced due to the fact that the sound wave intensity of the ultrasonic waves is overlarge; by sending the first ultrasonic information to the position coordinates of the target vehicle according to the target sound wave emission period and the target sound wave intensity, timely, directional and quantitative whistle is realized, interference of the ultrasonic information to other irrelevant vehicles is reduced, and the problems of high noise and large interference to surrounding personnel in the prior art are solved.

In some embodiments, determining a target vehicle to receive ultrasonic information and a first alert level for the target vehicle includes:

Acquiring position coordinates of at least one second vehicle relative to the first vehicle within a first preset range of the first vehicle;

displaying an image corresponding to the position coordinates of the second vehicle, and sending first prompt information to a driver of the first vehicle; the first prompting information is used for prompting a driver to select a first prompting grade from the displayed at least one first prompting grade and prompting the driver to select at least one target vehicle from the displayed image corresponding to the position coordinates;

And determining a first reminding grade and a target vehicle according to the selection operation of the driver for the first prompt information input.

Specifically, the first preset range may be a circular area with the position center of the first vehicle as a center and the first preset radius as a radius, and the first preset radius may be 5m, 10m, and the like; the number of the second vehicles is at least one, when the second vehicles are not in the first preset range of the first vehicle, the necessity of whistling is not indicated, and a series of calculation for whistling is avoided from wasting resources.

In addition, specifically, in a method for establishing a coordinate system, acquiring a position coordinate of at least one second vehicle relative to the first vehicle within a first preset range of the first vehicle may include: acquiring a linear distance between at least one second vehicle and a first vehicle in a first preset range of the first vehicle, and an azimuth angle and an elevation angle of the second vehicle relative to the first vehicle; and establishing a three-dimensional coordinate system by taking the first vehicle as a central origin, and determining the position coordinate of the second vehicle relative to the first vehicle according to the straight line distance, the azimuth angle and the elevation angle corresponding to the second vehicle. Therefore, the position of the second vehicle can be clearly known by the driver through the position coordinates of the second vehicle, and convenience is brought to the driver in selecting the target vehicle. Wherein the position coordinates of the second vehicle relative to the first vehicle can be expressed by the following formula:

θ_i＝(r_i,α_i,β_i)

Wherein i is the number of the second vehicles, and when the number of the second vehicles is large, the number of each second vehicle needs to be numbered for distinguishing; θ _i denotes position coordinates of the second vehicle numbered i with respect to the first vehicle; r _i denotes a straight line distance of the second vehicle numbered i from the first vehicle; α _i represents the azimuth of the second vehicle numbered i relative to the first vehicle; β _i denotes the elevation angle of the second vehicle, numbered i, relative to the first vehicle.

Specifically, an image corresponding to the position coordinates of the second vehicle is displayed, the image may include a virtual image and position coordinates of the second vehicle, and may further include a road lane line, an auxiliary line, and the like, and in addition, the virtual image of the second vehicle may be a vehicle picture, a special icon, or a three-dimensional image of the second vehicle, and the like, and may be set according to the vehicle function and the actual scene requirement, which is not particularly limited in the present application.

In addition, the first prompt information may be prompt information of "please select whistle reminding level and the vehicle needing to whistle" which appears in a pop-up window form, at this time, a reminding level selection page may appear on the screen of the first vehicle, the page includes a plurality of single boxes of reminding levels, after receiving the selection operation of the driver of the first vehicle on the reminding level, the reminding level selection page disappears, an image corresponding to the position coordinates of the second vehicle is displayed, the icons corresponding to the second vehicle in the image and other identifiers may be clicked and selected, and buttons of "all selection" and "all cancel selection" may be displayed on one side of the image, and different colors may be set to distinguish the selected and unselected vehicles. For example, continuing the description taking the virtual image of the second vehicle as the vehicle picture in the above example, the vehicle picture edge of the unselected second vehicle may be set to be gray, and the vehicle picture edge of the selected second vehicle may be set to be green. This enables a plurality of selection modes to be provided to the driver and helps the driver to clearly determine the selected second vehicle.

Specifically, the reminding level selected by the driver for the first prompt information is determined to be the first reminding level, and the second vehicle selected by the driver is determined to be the target vehicle.

In addition, when the vehicle is automatically driven, the first reminding level and the target vehicle can be determined by acquiring data such as the speed of the vehicle, the distance between the vehicle and each vehicle in a first preset range, the vehicle turn signal, the front wheel rotation angle of the vehicle, the vehicle navigation route, the surrounding light condition and the like through various sensors, radars, cameras and other devices arranged on the vehicle. As shown in fig. 2, assuming that the vehicle 201 is a first vehicle, and that the vehicle 202, the vehicle 203, and the vehicle 204 are all within a first preset range of the first vehicle 201, if the first vehicle 201 fails and the steering device cannot be controlled, it may be determined that the first alert level is the highest level, and the target vehicle is all vehicles within the first preset range including the vehicle 202, the vehicle 203, and the vehicle 204.

According to the technical scheme provided by the embodiment of the application, the position coordinates of at least one second vehicle relative to the first vehicle in the first preset range of the first vehicle are acquired, so that a driver can clearly know the position of the second vehicle through the position coordinates of the second vehicle, and convenience is brought to the driver to select the target vehicle; the image corresponding to the position coordinates of the second vehicle is displayed, the first prompt information is sent to the driver of the first vehicle, the operation required by the whistle can be indicated for the driver, the first prompt level and the target vehicle are determined according to the selection operation of the driver for the first prompt information input, the whistle can be carried out according to the subjective intention of the driver, and the experience and participation of the driver are met.

In some embodiments, after sending the first prompt to the driver of the first vehicle, further comprising:

Performing timing operation, and if the current timing time is longer than the preset time and the selection operation is not received, monitoring the health parameter value of the driver;

under the condition that the health parameter value of the driver is larger than a preset value, determining a first reminding grade and a target vehicle according to the current running track of the first vehicle;

And under the condition that the health parameter value of the driver is smaller than the preset value, determining that the first reminding level is the highest reminding level, and determining all second vehicles within the first preset range as target vehicles.

Specifically, when the first prompt message is sent, timing is started, the preset time can be 10 seconds, 15 seconds and the like, and the specific value can be set according to the test result and the actual application scene. Under the condition that the current counted time is longer than the preset time, the fact that the selection time of the driver is too long is indicated, if the selection operation of the driver is not received, the first prompt information cannot be considered possibly because the physical condition of the driver is bad, and therefore the health condition of the driver needs to be detected, specifically, the health parameter value of the driver can be obtained through comprehensive calculation through data such as the heartbeat frequency, the blood pressure data, the blink frequency and the respiratory frequency of the driver monitored by a driver monitoring system (Driver monitoring system, DMS), the health parameter value can be set to be a percentile, and the preset value can be 40, 50 and the like.

When the health parameter value of the driver is larger than the preset value, the fact that the body health of the driver is not problematic is indicated, the driver may not make a selection operation on the first prompt information because of other matters, time is wasted if the driver is enabled to make a selection operation again, traffic safety is possibly affected because of untimely whistle, therefore, the first reminding level and the target vehicle are determined according to the current running track of the first vehicle, and driving safety can be improved. For example, taking the case in the table as an example, if the current driving track of the first vehicle is that the first vehicle is meeting the oncoming vehicle in front, the alert level may be determined to be the alert, and the target vehicle is the oncoming vehicle of the first vehicle.

When the health parameter value of the driver is smaller than the preset value, the fact that the physical health of the driver is possibly problematic is indicated, and at the moment, the operation of the driver is possibly wrong, so that traffic accidents are caused, the first reminding level is determined to be the highest reminding level, all second vehicles in the first preset range are determined to be target vehicles, the second vehicles in the first range can be reminded to avoid in time, and the operations such as alarming, first aid and the like are performed.

According to the technical scheme provided by the embodiment of the application, by performing timing operation, if the current timing time is longer than the preset time and the selection operation is not received, the health parameter value of the driver is monitored, so that the physical condition of the driver can be timely focused; the health condition of the driver is determined through the comparison result of the health parameter value of the driver and the preset value, and the scheme of determining the first reminding grade and the target vehicle under two different conditions is executed simultaneously, so that the determination operation of the first reminding grade and the target vehicle is completed in effective time, the target vehicle is prompted in time, and the driving safety is improved.

In some embodiments, before transmitting the first ultrasonic information to the position coordinates of the target vehicle according to the target sound wave transmission period and the target sound wave intensity, the method further includes:

determining a target ultrasonic frequency corresponding to the road condition information of the current running road of the first vehicle according to a third corresponding relation between preset road condition information and ultrasonic frequency;

transmitting first ultrasonic information to a position coordinate of a target vehicle according to a target sound wave transmitting period and target sound wave intensity, including:

and according to the target sound wave emission period and the target sound wave intensity, sending first ultrasonic information with the sound wave frequency being the target ultrasonic frequency to the position coordinates of the target vehicle.

Specifically, the road condition information can indicate the road condition of the running road within the third preset range of the vehicle, the road type, the number of obstacles, the occupied area of the obstacles, the number of curves and other data of the running road can be used as the judging standard, under the condition of poor road condition, the ultrasonic transmission can be multiply hindered, the diffraction capacity of the low-frequency ultrasonic wave is better, and the propagation performance on the road with poor road condition is better. Further, the third preset range may be a circular area with the center of the first vehicle as a center, the third preset radius as a radius, and the third preset radius may be 20m, 25m, or the like.

As an example, if the road type is expressway, the number of obstacles in the third preset range of the first vehicle is smaller than the preset number of obstacles, and the number of curves is smaller than the preset number of curves, determining that the road condition of the driving road in the third preset range is optimal, and the corresponding target ultrasonic frequency is the first preset frequency; if the road type is an urban road, determining that the road condition of the driving road in the third preset range is good, and the corresponding target ultrasonic frequency is the second preset frequency, wherein the number of obstacles in the third preset range of the first vehicle is larger than the number of preset obstacles and the number of curves is smaller than the number of preset curves, or the number of obstacles is smaller than the number of preset obstacles and the number of curves is larger than the number of preset curves; if the road type is a rural road, the number of the obstacles in the third preset range of the first vehicle is larger than the number of the preset obstacles, and the number of the curves is larger than the number of the preset curves, determining that the road condition of the running road in the third preset range is poor, and the corresponding target ultrasonic frequency is the third preset frequency. Specifically, the first preset frequency is higher than the second preset frequency, the second preset frequency is higher than the third preset frequency, and the first preset frequency, the second preset frequency, the third preset frequency, the number of preset obstacles and the number of preset curves can be set according to the test result and the actual application scene.

According to the technical scheme provided by the embodiment of the application, the target ultrasonic frequency corresponding to the road condition information of the current running road of the first vehicle is determined according to the third corresponding relation between the preset road condition information and the ultrasonic frequency, the target ultrasonic frequency can be determined according to the road condition, and the diffraction capacity of the first ultrasonic information can be regulated, so that the transmission capacity of ultrasonic waves on the road with a large number of obstacles and curves is improved; according to the target sound wave emission period and the target sound wave intensity, the first ultrasonic information with the sound wave frequency being the target ultrasonic frequency is sent to the position coordinates of the target vehicle, so that the first ultrasonic information can be received by the target vehicle, the reminding function of the ultrasonic information is guaranteed, and the driving safety is improved.

In some embodiments, the first vehicle is provided with an ultrasonic detection device, and the first vehicle is provided with a sound playing device; the embodiment further includes:

Under the condition that the user enters the first vehicle is detected, inquiry information is sent to the user, and the inquiry information is used for inquiring whether second ultrasonic information sent by the third vehicle is received or not;

Acquiring feedback information input by a user based on the inquiry information, and if the feedback information indicates to receive second ultrasonic information, receiving the second ultrasonic information through the ultrasonic detection device, wherein the second ultrasonic information carries the license plate number and the second reminding grade of the third vehicle;

Analyzing the second ultrasonic information through the ultrasonic detection device to obtain the intention corresponding to the license plate number and the second reminding level of the third vehicle, and sending the intention corresponding to the license plate number and the second reminding level of the third vehicle to the sound playing device through the ultrasonic detection device;

And playing the corresponding intention of the license plate number and the second reminding level of the third vehicle through the sound playing device.

Specifically, because some users may not want to be disturbed by the information sent by other vehicles, when the vehicle detects that the user enters the vehicle, the query information of whether the second ultrasonic information sent by the third vehicle is received is sent to the user, and when the feedback information input by the user based on the query information indicates that the second ultrasonic information is not received, the user will be satisfied, and the driving experience of the user is improved.

In addition, specifically, the inquiry information may be sent by displaying the popup window information capable of being selected by touch on the central control screen of the first vehicle, or may be sent to the client bound to the first vehicle by playing a voice broadcast with the content "please ask you if you agree to receive the ultrasonic information from other vehicles" by the in-vehicle sound playing device of the first vehicle. Accordingly, the feedback information input by the user based on the inquiry information may be a click operation of a function key of "receiving" or "not receiving" the content on the first vehicle screen, or may be a sentence in which the voice response includes the keyword "consent" or "disagreement".

The second prompt level is one of preset prompt levels, and is a prompt level corresponding to the second ultrasonic information determined by the driver of the third vehicle.

Specifically, the second ultrasonic information is analyzed to obtain the intention corresponding to the second reminding level, so that the first vehicle can play the intention. It should be noted that, under the condition that the number of the whistle events corresponding to each reminding level is too large, the first vehicle may not be able to analyze the intention corresponding to the second reminding level only according to the second reminding level, and needs to make a judgment together by combining the current navigation information of the first vehicle, so as to improve the accuracy of the analysis result and provide data support for the follow-up first vehicle to make avoidance actions for the third vehicle.

For example, taking the above-mentioned correspondence table of alert levels and whistle events as an example, as shown in fig. 2, taking the vehicle 201 as a first vehicle, and the vehicles 202, 203 and 204 are all within the ultrasonic information receiving range of the first vehicle, if the alert level received by the first vehicle 201 is the alert level, then the intention may be that the third vehicle will turn or will meet; assuming that the current navigation information of the first vehicle 201 in fig. 2 indicates that the first vehicle 201 is still 1000 meters from the turning intersection, it is determined that the second reminding level corresponds to the intention that the third vehicle will meet, and the license plate number of the third vehicle is XXX, and then voice broadcasting of the "the vehicle with the license plate number XXX is about to meet the vehicle" will be performed in the first vehicle.

It should be noted that, the playing frequency that the sound playing device plays the license plate number of the third vehicle and the second reminding level corresponding to the intention is in the frequency range audible to the human ear, so that the influence of whistling noise to surrounding personnel can be avoided while vehicle information is transmitted, and the playing frequency can be controlled according to the second reminding level. For example, if the second alert level is the highest level, the control increases the play frequency. In this way, the receiver driver can be prompted to different degrees according to the emergency degree of the event. In addition, the volume of the sound playing device can be adjusted autonomously by the driver.

According to the technical scheme provided by the embodiment of the application, under the condition that the user enters the first vehicle, inquiry information is sent to the user, feedback information input by the user based on the inquiry information is obtained, if the feedback information indicates to receive the second ultrasonic information, the second ultrasonic information is received through the ultrasonic detection device, so that different willingness of the user can be met, and the driving experience of the user is improved; the second ultrasonic information is analyzed to obtain the corresponding intention of the license plate number and the second reminding level of the third vehicle, the corresponding intention of the license plate number and the second reminding level of the third vehicle is played in the vehicle of the first vehicle, the influence of whistling noise on surrounding personnel can be avoided while the vehicle information is transmitted, and the driver can adjust the volume according to the self requirement, so that the problem of large whistling noise of the vehicle is avoided.

In some embodiments, after playing the license plate number of the third vehicle and the intention corresponding to the second reminding level by the sound playing device, the method further includes:

Acquiring image information in a second preset range of the first vehicle;

determining the position of the third vehicle relative to the first vehicle according to the image information and the license plate number of the third vehicle;

according to the intention and the direction corresponding to the second reminding level, determining the avoidance operation of the first vehicle, and sending second reminding information to the user, wherein the second reminding information is used for reminding the driver to avoid according to the avoidance operation.

Specifically, the second preset range may be a circular area with the first vehicle center as a center and the second preset radius as a radius, and the second preset radius may be 10m, 12m, or the like, and the second preset radius may be the same as or different from the first preset radius. The image information may be a panoramic looking-around image of the first vehicle within a second predetermined range.

In addition, specifically, license plate number detection is performed according to the image information, a target license plate number which is the same as the license plate number of the third vehicle in the detected image information is determined, and position coordinates of the vehicle corresponding to the target license plate number are determined, so that the azimuth of the third vehicle relative to the first vehicle is obtained.

Specifically, the second prompt message can be displayed on the central control screen of the first vehicle in a popup mode, or can be prompted in the first vehicle in a voice broadcast mode, and under the condition that a user has no special requirement, the voice broadcast mode is used by default, so that the response time of a driver can be reduced, and the avoidance safety is improved.

Under the condition that the number of surrounding vehicles is large, the specific position of the third vehicle is difficult to determine through eyes of a driver, the time spent for making a decision on the basis is relatively long, the avoidance operation cannot be timely made aiming at the intention of the third vehicle, and the safety is not high. According to the intention and the direction corresponding to the second reminding level, the avoidance operation of the first vehicle is determined, and the second reminding information is sent to the user, so that the user can make corresponding avoidance operation according to the second reminding information, and the driving safety is improved.

For example, as an example, as shown in fig. 2, taking the vehicle 203 as the first vehicle and the vehicle 202 as the third vehicle, determining that the third vehicle 202 is behind the first vehicle 203, if the second reminding level of the third vehicle 202 corresponds to that the lane in which the first vehicle 202 is located is intended to be changed, the second reminding information content may be "the right behind vehicle is about to change lane, please accelerate"; if the second alert level of the third vehicle 202 corresponds to the intention of completing the overtaking through the lane in which the first vehicle 202 is located, the second alert information content may be "the right rear vehicle is about to overtake, please slow down"; if it is determined that the third vehicle is the vehicle 201, the second prompting level of the third vehicle 201 corresponds to the intention of asking for help for the failure of the vehicle, and the content of the second prompting information may be "the failure of the rear vehicle, please accelerate lane change, avoid, and call for help".

According to the technical scheme provided by the embodiment of the application, the image information in the second preset range of the first vehicle is acquired; according to the image information and the license plate number of the third vehicle, the azimuth of the third vehicle relative to the first vehicle is determined, a basis is provided for subsequent avoidance operation, the avoidance operation of the first vehicle is determined according to the intention and the azimuth corresponding to the second reminding level, and the second reminding information is sent to the user, so that the user can quickly make corresponding avoidance operation according to the second reminding information, and driving safety is improved.

In some embodiments, in the first correspondence, the alert level and the sound wave emission period are in a negative linear correlation; in the second corresponding relation, the distance and the sound wave intensity are in positive correlation; in the third corresponding relation, the road condition information and the ultrasonic frequency are in positive correlation.

Specifically, in the first corresponding relation, the reminding level and the sound wave emission period are in negative correlation, different reminding levels are in one-to-one correspondence with different sound wave emission periods, the higher the reminding level is, the larger the corresponding value of the reminding level is, the smaller the corresponding value of the sound wave emission period is, at least one fixed coefficient exists between the reminding level and the sound wave generation period, and the relation of mutual influence between the reminding level and the sound wave emission period can be clearly represented.

In addition, in particular, in the second correspondence, since the distance is not discriminated from the positive and negative in the case of using the distance simultaneously with the direction, and the sound wave intensity is not negative, the distance and the sound wave intensity may be in a positive linear correlation, and the greater the distance, the greater the sound wave intensity by a predetermined coefficient as the connection.

Specifically, in the third corresponding relationship, the road condition information and the ultrasonic frequency are in a positive correlation, that is, the better the road condition information indicates, the flatter, straight and less obstacle is represented by the road, the stronger diffraction capacity is not required for sending the ultrasonic information on the road, and the diffraction capacity of the ultrasonic wave is in a negative correlation with the ultrasonic frequency of the road, so that the road condition information and the diffraction capacity of the ultrasonic wave are in a negative correlation, and in a positive linear correlation with the ultrasonic frequency, that is, the better the road condition is, the smaller the ultrasonic frequency is.
