[0026] A vehicle horn method and device according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0027] Figure 1 It is a flow chart of a vehicle horn honking method provided in an embodiment of the present application. Figure 1 The vehicle horn method can be executed by the vehicle controller. Figure 1 As shown, the vehicle horn method comprises:

[0028] S101, determining a target vehicle to receive ultrasonic information and a first reminder level for the target vehicle; wherein the ultrasonic information is emitted by an ultrasonic transmitting device installed on a first vehicle.

[0029] It should be noted that the frequency of ultrasonic information is greater than the maximum value of the frequency range audible to the human ear, that is, greater than 20,000 Hz. Therefore, when vehicles interact by honking their horns through ultrasonic information, it will not cause interference to people outside the vehicle.

[0030] In addition, an ultrasonic transmitting device is installed on the first vehicle, and the first vehicle can transmit ultrasonic information through the ultrasonic transmitting device.

[0031] Specifically, the number of target vehicles is at least one; selecting the target vehicle and the first reminder level can provide data support for determining the honking direction and honking cycle of the subsequent first vehicle.

[0032] S102, determining a target sound wave emission period corresponding to the first reminder level according to a preset first corresponding relationship between the reminder level and the sound wave emission period.

[0033] Specifically, the correspondence between the pre-set reminder level and the sound wave emission period can be a negative correlation, that is, the higher the reminder level, the shorter the sound wave emission period, and at the same time, the higher the sound wave emission frequency, which can reflect the urgency of the event. Specifically, it is a negative linear correlation or other negative correlation, which can be set according to the needs of the scene.

[0034] A target sound wave emission period corresponding to the first reminder level is determined so that the first vehicle can emit ultrasonic information with the target sound wave emission period, and can reflect the urgency of the first vehicle through the target sound wave emission period, thereby providing support for subsequent target vehicles to judge the urgency of the first vehicle through the sound wave emission period of ultrasonic information.

[0035] In addition, it should be noted that the reminder level and the vehicle's honking event should also have a preset correspondence, so that the driver can determine the first reminder level based on the preset correspondence and the honking event, avoiding problems caused by the driver's incorrect selection of the first reminder level. The preset correspondence can be a one-to-many relationship between reminder levels and honking events.

[0036] Specifically, as an example, the correspondence between the above preset reminder levels and the sound wave emission cycles and the preset correspondence may be shown in the following table:

[0037]

[0038] The number of reminder levels can be 3, 4, 5, etc., and the corresponding number of sound wave emission cycles is the same as the number of reminder levels. The above table is only one of many embodiments. The specific number and content of reminder levels and sound wave emission cycles can be set according to the needs of actual application scenarios and different vehicle functions. This application does not specifically limit this.

[0039] S103, determining a target distance between the first vehicle and the target vehicle, and determining a target sound wave intensity corresponding to the target distance according to a preset second corresponding relationship between the distance and the sound wave intensity.

[0040] Specifically, the target distance is a straight-line distance, excluding the length of a feasible path between the first vehicle and the target vehicle; the target distance can be obtained based on a distance detection device installed on the first vehicle, such as a laser radar, a distance sensor, and the like.

[0041] In addition, the second corresponding relationship between the preset distance and the sound wave intensity can be a positive linear correlation, that is, different distances correspond to different sound wave intensities one by one, and the greater the distance, the greater the sound wave intensity. Since the first vehicle may be traveling during the whistle process, the distance between the first vehicle and the target vehicle may change, and the corresponding target sound wave intensity also needs to be changed. For example, when the target distance is reduced, it means that the distance between the first vehicle and the target vehicle is shortened. If the original target sound wave intensity is still used, it may affect the target vehicle. At this time, the sound wave intensity is reduced accordingly to ensure that the ultrasonic wave energy received by the target vehicle is within a suitable and safe range. In addition, determining the target sound wave intensity corresponding to the target distance can ensure that the target vehicle can receive the ultrasonic wave emitted by the first vehicle while not affecting the driving of surrounding vehicles due to the excessive sound wave intensity of the ultrasonic wave.

[0042] Specifically, the target sound wave intensity can be calculated by the following formula:

[0043] P t =P*L t

[0044] Where P represents the preset ultrasonic intensity, L t Can represent the target distance at time t, P t Indicates the target sound wave intensity at time T. Specifically, as an example, it can be understood that when the target distance is 1m, the ultrasonic wave intensity received by the target vehicle is P. When the target distance increases or decreases by 1m, the target sound wave intensity increases or decreases by PW / m 2 ; The preset ultrasonic intensity can be 100W / m 2 , 200W / m 2 , and can also be set according to specific test results, which is not limited in this application. It should be noted that since the direction in which the vehicle sends ultrasonic information can be in any direction, the target distance in the above formula cannot be a negative value, and the target ultrasonic intensity cannot be a negative value either.

[0045] S104, sending first ultrasonic wave information to the position coordinates of the target vehicle according to the target sound wave emission period and the target sound wave intensity.

[0046] The first ultrasonic information carries the first reminder level, and the ultrasonic detection device installed on the target vehicle analyzes the intention corresponding to the first reminder level and sends the intention to the in-vehicle sound playback device of the target vehicle for voice playback.

[0047] Specifically, the position coordinates of the target vehicle can be determined by establishing a coordinate system. In addition, when the number of target vehicles is greater than a preset number, the direction in which the first ultrasonic information is sent can be determined for the position coordinates of multiple target vehicles. For example, as an example, assuming that the first vehicle is about to change lanes to the right, the first vehicle needs to prompt the vehicles in front, right front, and right rear. Therefore, it can be determined that the direction in which the first vehicle sends the first ultrasonic information can be the front, right front, and right rear. Sending the first ultrasonic information to the position coordinates of the target vehicle can reduce the interference of the ultrasonic information on other vehicles that do not need to receive the horn information.

[0048] In addition, the first ultrasonic information may also carry the license plate number of the first vehicle, upcoming vehicle actions, and the like.

[0049] Specifically, the ultrasonic detection device on the target vehicle can be installed inside the target vehicle or outside the target vehicle, and can include an ultrasonic probe, an ultrasonic controller and a transmission device. 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 sound playback device inside the target vehicle.

[0050] The target vehicle can control the volume of the voice played in the car by manually rotating or turning the volume adjustment device, or sliding the volume slider on the screen.

[0051] According to the technical solution provided in the embodiment of the present application, by determining the target vehicle to be received ultrasonic information and the first reminder level for the target vehicle, interference of honking on surrounding personnel is avoided, and data support is provided for the subsequent first vehicle to determine the honking direction and honking period; by determining the target sound wave emission period corresponding to the first reminder level according to the first corresponding relationship between the preset reminder level and the sound wave emission period, the urgency of the event can be reflected and the target vehicle can be helped to make a 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 relationship between the preset distance and the sound wave intensity, it can be ensured that the target vehicle can receive the ultrasonic wave emitted by the first vehicle while not affecting the driving of surrounding vehicles due to the excessive sound wave intensity of the ultrasonic wave; by sending the first ultrasonic wave 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 honking is achieved, the interference of ultrasonic wave information on other unrelated vehicles is reduced, and the problem of high noise and great interference to surrounding personnel in the prior art is solved.

[0052] In some embodiments, determining a target vehicle to receive ultrasonic information and a first reminder level for the target vehicle includes:

[0053] Acquire the position coordinates of at least one second vehicle within a first preset range of the first vehicle relative to the first vehicle;

[0054] Displaying an image corresponding to the position coordinates of the second vehicle, and sending a first prompt message to the driver of the first vehicle; the first prompt message is used to prompt the driver to select a first reminder level from at least one displayed first reminder level, and prompt the driver to select at least one target vehicle from the image corresponding to the displayed position coordinates;

[0055] A first reminder level and a target vehicle are determined according to a selection operation input by the driver in response to the first prompt information.

[0056] Specifically, the first preset range can be a circular area with the position center of the first vehicle as the center and the first preset radius as the radius. The first preset radius can be 5m, 10m, etc.; the number of the second vehicle is at least one. When there is no second vehicle within the first preset range of the first vehicle, it means that there is no need to honk the horn, avoiding wasting resources to make a series of calculations for honk.

[0057] In addition, specifically, the method of establishing a coordinate system to obtain the position coordinates of at least one second vehicle within the first preset range of the first vehicle relative to the first vehicle may include: obtaining the straight-line distance between at least one second vehicle within the first preset range of the first vehicle and the first vehicle, as well as the azimuth and elevation angle of the second vehicle relative to the first vehicle; establishing a three-dimensional coordinate system with the first vehicle as the center origin, and determining the position coordinates of the second vehicle relative to the first vehicle based on the straight-line distance, azimuth and elevation angle corresponding to the second vehicle. In this way, the driver can clearly understand the position of the second vehicle through the position coordinates of the second vehicle, which facilitates the driver to select the target vehicle. Among them, the position coordinates of the second vehicle relative to the first vehicle can be expressed by the following formula:

[0058] θ i =(r i , α i , β i )

[0059] Wherein, i is the number of the second vehicle. When the number of the second vehicles is large, each second vehicle needs to be numbered for distinction; θ i represents the position coordinates of the second vehicle numbered i relative to the first vehicle; r i represents the straight-line distance between the second vehicle numbered i and the first vehicle; α i represents the azimuth angle of the second vehicle numbered i relative to the first vehicle; β i Represents the elevation angle of the second vehicle numbered i relative to the first vehicle.

[0060] Specifically, the 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 also include road lane lines, auxiliary lines, etc. 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, etc., which can be set according to the vehicle functions and actual scene requirements, and this application does not make specific limitations on this.

[0061] In addition, the first prompt information may be a prompt information in the form of a pop-up window with the content "Please select the horn reminder level and the vehicle to which the horn needs to be sounded". At this time, a reminder level selection page may appear on the screen of the first vehicle, and the page includes radio buttons for multiple reminder levels. After receiving the selection operation of the reminder level by the driver of the first vehicle, the reminder level selection page disappears, and the image corresponding to the position coordinates of the second vehicle is displayed. The icons and other symbols corresponding to the second vehicle in the image can be clicked and selected. The buttons of "Select All" and "Cancel All Selections" can also be displayed on one side of the image, and different colors can be set to distinguish between selected and unselected vehicles. For example, taking the virtual image of the second vehicle in the above example as a vehicle picture as an example to continue the explanation, the edge of the vehicle picture of the unselected second vehicle can be set to gray, and the edge of the vehicle picture of the selected second vehicle can be set to green. This achieves the goal of providing the driver with a variety of selection methods and helping the driver to clearly determine the selected second vehicle.

[0062] Specifically, the reminder level selected by the driver for the first prompt information is determined to be the first reminder level, and the second vehicle selected by the driver is determined to be the target vehicle.

[0063] In addition, when the vehicle is autonomous, various sensors, radars, cameras and other devices installed on the vehicle can be used to obtain data such as the vehicle's speed, the distance between the vehicle and each vehicle within the first preset range, the vehicle's turn signal, the vehicle's front wheel angle, the vehicle's navigation route, and surrounding lighting conditions to determine the first warning level and the target vehicle. Figure 2 As shown, assuming that vehicle 201 is the first vehicle, vehicles 202, 203 and 204 are all within the first preset range of the first vehicle 201, if the first vehicle 201 fails and the steering device cannot be controlled, it can be determined that the first reminder level is the highest level, and the target vehicles are all vehicles within the first preset range including vehicles 202, 203 and 204.

[0064] According to the technical solution provided in the embodiment of the present application, by acquiring the position coordinates of at least one second vehicle relative to the first vehicle within a first preset range of the first vehicle, the driver can clearly understand the direction of the second vehicle through the position coordinates of the second vehicle, thereby providing convenience for the driver to select a target vehicle; the image corresponding to the position coordinates of the second vehicle is displayed, and a first prompt message is sent to the driver of the first vehicle, which can indicate to the driver the operations required to honk the horn, determine the first reminder level and the target vehicle based on the selection operation input by the driver for the first prompt message, and can honk according to the driver's subjective wishes, thereby satisfying the driver's sense of experience and participation.

[0065] In some embodiments, after sending the first prompt information to the driver of the first vehicle, the method further includes:

[0066] Perform a timing operation, and if the current timing time is greater than the preset time and no selection operation is received, monitor the health parameter value of the driver;

[0067] When the health parameter value of the driver is greater than a preset value, determining a first reminder level and a target vehicle according to a current driving trajectory of the first vehicle;

[0068] When the health parameter value of the driver is less than a preset value, the first reminder level is determined as the highest reminder level, and all second vehicles within the first preset range are determined as target vehicles.

[0069] Specifically, the timing starts when the first prompt message is sent. The preset time can be 10 seconds, 15 seconds, etc. The specific value can be set according to the test results and the actual application scenario. If the current timed time is greater than the preset time, it means that the driver's selection time is too long. If the driver's selection operation is still not received, it may be because the driver's physical condition is not good and cannot take into account the first prompt message. Therefore, it is necessary to detect the driver's health status. Specifically, the driver's health parameter value can be obtained by comprehensively calculating the driver's heart rate, blood pressure data, blinking frequency, and breathing rate monitored by the driver monitoring system (Driver monitoring system, DMS). The health parameter value can be set to a percentage system, and the preset value can be 40, 50, etc.

[0070] When the driver's health parameter value is greater than the preset value, it means that the driver's physical health is fine. The driver may not have made a selection operation for the first prompt information due to other matters. If the driver is asked to make a selection operation again, it will waste time and may affect traffic safety due to untimely honking. Therefore, determining the first reminder level and the target vehicle according to the current driving trajectory of the first vehicle can improve driving safety. For example, taking the case in the above table as an example, if the current driving trajectory of the first vehicle is to meet an oncoming vehicle in front, the reminder level can be determined to be a prompt, and the target vehicle is the oncoming vehicle of the first vehicle.

[0071] When the driver's health parameter value is less than the preset value, it means that the driver may have problems with his physical health. At this time, the driver's operation may be wrong, resulting in a traffic accident. Therefore, the first reminder level is determined as the highest reminder level, and all second vehicles within the first preset range are determined as target vehicles. The second vehicles within the first range can be reminded to avoid in time, and perform alarms, first aid and other operations.

[0072] According to the technical solution provided in the embodiment of the present application, by performing a timing operation, if the current timing time is greater than the preset time and no selection operation is received, the driver's health parameter value is monitored, so that timely attention can be paid to the driver's physical condition; the driver's health condition is determined by comparing the driver's health parameter value with the preset value, and the schemes for determining the first reminder level and the target vehicle under two different situations are executed at the same time, thereby completing the determination operation of the first reminder level and the target vehicle within the effective time, so that the target vehicle can be prompted in a timely manner subsequently, thereby improving driving safety.

[0073] In some embodiments, before sending the first ultrasonic wave information to the position coordinates of the target vehicle according to the target sound wave emission period and the target sound wave intensity, the method further includes:

[0074] Determining a target ultrasonic frequency corresponding to the road condition information of the road currently traveled by the first vehicle according to a preset third correspondence relationship between the road condition information and the ultrasonic frequency;

[0075] According to the target sound wave emission period and the target sound wave intensity, the first ultrasonic wave information is sent to the position coordinates of the target vehicle, including:

[0076] According to the target sound wave emission period and the target sound wave intensity, first ultrasonic wave information having a sound wave frequency that is a target ultrasonic wave frequency is sent to the position coordinates of the target vehicle.

[0077] Specifically, the road condition information can indicate the quality of the road condition of the vehicle within the third preset range, and can be judged by the road type, number of obstacles, area occupied by obstacles, number of bends and other data of the road. In the case of poor road conditions, ultrasonic transmission will be subject to multiple obstacles, while low-frequency ultrasonic waves have better diffraction ability and better propagation performance on roads with poor road conditions. In addition, the third preset range can be a circular area with the center of the first vehicle as the center and the third preset radius as the radius, and the third preset radius can be 20m, 25m, etc.

[0078] As an example, if the road type is a highway, the number of obstacles within the third preset range of the first vehicle is less than the preset number of obstacles, and the number of curves is less than the preset number of curves, then the road condition within the third preset range is determined to be excellent, and the corresponding target ultrasonic frequency is the first preset frequency; if the road type is an urban road, the number of obstacles within the third preset range of the first vehicle is greater than the preset number of obstacles and the number of curves is less than the preset number of curves, or the number of obstacles is less than the preset number of obstacles and the number of curves is greater than the preset number of curves, then the road condition within the third preset range is determined to be good, and the corresponding target ultrasonic frequency is the second preset frequency; if the road type is a rural road, the number of obstacles within the third preset range of the first vehicle is greater than the preset number of obstacles, and the number of curves is greater than the preset number of curves, then the road condition within the third preset range is determined to be poor, and the corresponding target ultrasonic frequency is the third preset frequency. Specifically, the first preset frequency is higher than the second preset frequency, and the second preset frequency is higher than the third preset frequency. The first preset frequency, the second preset frequency, the third preset frequency, the preset number of obstacles, and the preset number of curves can all be set according to the test results and actual application scenarios.

[0079] According to the technical solution provided in the embodiment of the present application, by determining the target ultrasonic frequency corresponding to the road condition information of the road currently traveled by the first vehicle according to the third corresponding relationship between the pre-set road condition information and the ultrasonic frequency, the target ultrasonic frequency can be determined according to the road condition, and the diffraction ability of the first ultrasonic information can be adjusted, thereby improving the propagation ability of ultrasonic waves on roads with a large number of obstacles and bends; according to the target sound wave emission period and the target sound wave intensity, the first ultrasonic information with the target ultrasonic frequency is sent to the position coordinates of the target vehicle, which can ensure that the first ultrasonic information can be received by the target vehicle, thereby ensuring the reminder function of the ultrasonic information and improving driving safety.

[0080] In some embodiments, an ultrasonic detection device is installed on the first vehicle, and a sound playback device is provided in the first vehicle; this embodiment also includes:

[0081] When it is detected that the user enters the first vehicle, an inquiry message is sent to the user, where the inquiry message is used to inquire whether to receive the second ultrasonic information sent by the third vehicle;

[0082] Acquire feedback information input by the user based on the inquiry information, and if the feedback information indicates receiving second ultrasonic information, receive the second ultrasonic information through an ultrasonic detection device, where the second ultrasonic information carries the license plate number of the third vehicle and the second reminder level;

[0083] The ultrasonic detection device analyzes the second ultrasonic information to obtain the license plate number of the third vehicle and the intention corresponding to the second reminder level, and the ultrasonic detection device sends the license plate number of the third vehicle and the intention corresponding to the second reminder level to the sound playback device;

[0084] The license plate number of the third vehicle and the intention corresponding to the second reminder level are played through the sound playing device.

[0085] Specifically, since some users may not want to be disturbed by information sent by other vehicles, when the vehicle detects that a user has entered the vehicle, an inquiry message is sent to the user, asking whether to receive the second ultrasonic information sent by a third vehicle. If the user inputs feedback information based on the inquiry message indicating not to receive the second ultrasonic information, the user's wishes are met and the user's driving experience is improved.

[0086] In addition, specifically, the inquiry information can be sent by displaying a pop-up window that can be selected by touch on the central control screen of the first vehicle, or by playing a voice broadcast of "Do you agree to receive ultrasonic information from other vehicles" through the in-vehicle sound playback device of the first vehicle, or by sending the inquiry information to a client bound to the first vehicle. Accordingly, the feedback information input by the user based on the inquiry information can be a click operation on the function button with the content "Receive" or "Do not Receive" on the screen of the first vehicle, or a voice answer including the key words "Agree" or "Disagree".

[0087] It should be noted that the second prompt level is one of the preset prompt levels, and is the prompt level corresponding to the second ultrasonic information determined by the driver of the third vehicle.

[0088] Specifically, the second ultrasonic information is parsed to obtain the intention corresponding to the second reminder level, so that the first vehicle can play the intention. It should be noted that when there are too many honking events corresponding to each reminder level, the first vehicle may not be able to parse the intention corresponding to the second reminder level based on the second reminder level alone, and it is necessary to make a judgment in combination with the current navigation information of the first vehicle, thereby improving the accuracy of the parsing result and providing data support for the subsequent first vehicle to take evasive action against the third vehicle.

[0089] For example, taking the above table of correspondence between reminder levels and horn events as an example, Figure 2 As shown, vehicle 201 is taken as the first vehicle, and vehicles 202, 203 and 204 are all within the ultrasonic information receiving range of the first vehicle. The first vehicle 201 receives the reminder level as the prompt level, and the intention may be that the third vehicle is about to turn or meet. Assuming Figure 2If the current navigation information of the first vehicle 201 indicates that the first vehicle 201 is still 1000 meters away from the turning intersection, it is determined that the intention corresponding to the second reminder level is that a third vehicle is about to meet, and the license plate number of the third vehicle is XXX, then a voice broadcast of "the vehicle with the license plate number XXX is about to meet this vehicle" will be made in the first vehicle.

[0090] It should be noted that the license plate number of the third vehicle and the intended playback frequency corresponding to the second reminder level played by the sound playback device are within the frequency range audible to the human ear, so that the vehicle information can be transmitted while avoiding the impact of the horn noise on the surrounding people. The playback frequency can also be controlled according to the second reminder level. For example, when the second reminder level is the highest level, the playback frequency is controlled to be increased. In this way, different degrees of prompts can be given to the receiving driver according to the urgency of the event. In addition, the volume of the sound playback device can be adjusted independently by the driver.

[0091] According to the technical solution provided in the embodiment of the present application, when it is detected that the user has entered the first vehicle, an inquiry message is sent to the user, and feedback information input by the user based on the inquiry message is obtained. If the feedback information indicates receiving the second ultrasonic information, the second ultrasonic information is received by the ultrasonic detection device, which can meet the different wishes of the user and improve the user's driving experience; by parsing the second ultrasonic information, the license plate number of the third vehicle and the intention corresponding to the second reminder level are obtained, and the license plate number of the third vehicle and the intention corresponding to the second reminder level are played in the first vehicle, which can avoid the impact of the horn noise on the surrounding people while disseminating the vehicle information. The driver can also adjust the volume according to his own needs, avoiding the problem of loud vehicle horn noise.

[0092] In some embodiments, after the license plate number of the third vehicle and the intention corresponding to the second reminder level are played by the sound playing device, the method further includes:

[0093] Acquire image information within a second preset range of the first vehicle;

[0094] Determining the position of the third vehicle relative to the first vehicle based on the image information and the license plate number of the third vehicle;

[0095] According to the intention and direction corresponding to the second reminder level, the avoidance operation of the first vehicle is determined, and a second prompt message is sent to the user, where the second prompt message is used to prompt the driver to perform avoidance according to the avoidance operation.

[0096] Specifically, the second preset range may be a circular area with the center of the first vehicle as the center and the second preset radius as the radius, the second preset radius may be 10m, 12m, etc., the second preset radius may be the same as the first preset radius or may be different. The image information may be a panoramic surround image within the second preset range of the first vehicle.

[0097] In addition, specifically, license plate number detection is performed based on image information, a target license plate number that is the same as the license plate number of the third vehicle is detected in the image information, and the position coordinates of the vehicle corresponding to the target license plate number are determined to obtain the orientation of the third vehicle relative to the first vehicle.

[0098] Specifically, the second prompt information can be displayed in the form of a pop-up window on the central control screen of the first vehicle, or can be used as a voice broadcast inside the first vehicle. If the user has no special requirements, the voice broadcast form is used by default, which can reduce the driver's reaction time and improve avoidance safety.

[0099] When there are many vehicles around, it is difficult for the driver to determine the specific position of the third vehicle through his eyes, and it takes a relatively long time to make a decision based on this. It is not possible to make an evasive operation in time according to the intention of the third vehicle, which is not safe. According to the intention and direction corresponding to the second reminder level, the evasive operation of the first vehicle is determined, and the second prompt information is sent to the user, so that the user can make a corresponding evasive operation according to the second prompt information, thereby improving driving safety.

[0100] For example, as an example, Figure 2 As shown, vehicle 203 is taken as the first vehicle and vehicle 202 is taken as the third vehicle. It is determined that the third vehicle 202 is behind the right of the first vehicle 203. If the second reminder level of the third vehicle 202 corresponds to the intention of changing lanes to the lane where the first vehicle 202 is located, the second prompt information content may be "the vehicle behind you is about to change lanes, please speed up"; if the second reminder level of the third vehicle 202 corresponds to the intention of overtaking through the lane where the first vehicle 202 is located, the second prompt information content may be "the vehicle behind you is about to overtake, please slow down"; if the third vehicle is determined to be vehicle 201, and the second reminder level of the third vehicle 201 corresponds to the intention of asking for help due to a vehicle breakdown, the second prompt information content may be "the vehicle behind you is broken down, please speed up and change lanes to avoid it, and call for help".

[0101] According to the technical solution provided in the embodiment of the present application, by acquiring image information within the second preset range of the first vehicle; determining the position of the third vehicle relative to the first vehicle based on the image information and the license plate number of the third vehicle, providing a basis for subsequent avoidance operations, determining the avoidance operation of the first vehicle based on the intention and position corresponding to the second reminder level, and sending a second prompt message to the user, the user can quickly make corresponding avoidance operations based on the second prompt message, thereby improving driving safety.

[0102] In some embodiments, in the first corresponding relationship, the reminder level and the sound wave emission period are negatively linearly correlated; in the second corresponding relationship, the distance and the sound wave intensity are positively correlated; in the third corresponding relationship, the road condition information and the ultrasonic frequency are positively correlated.

[0103] Specifically, in the first corresponding relationship, the reminder level and the sound wave emission period are negatively correlated, different reminder levels correspond one-to-one to different sound wave emission periods, and the higher the reminder level, the larger the corresponding value of the reminder level, and the smaller the corresponding value of the sound wave emission period. There is at least one fixed coefficient between the reminder level and the sound wave generation period, which can clearly indicate the relationship of mutual influence between the reminder level and the sound wave emission period.

[0104] In addition, specifically, in the second corresponding relationship, since the distance has no positive or negative distinction when used together with the direction, and the sound wave intensity has no negative value, the distance and the sound wave intensity can be positively linearly correlated, connected by a preset coefficient, and the greater the distance, the greater the sound wave intensity.

[0105] Specifically, in the third corresponding relationship, the road condition information and the ultrasonic frequency are positively correlated, that is, the better the road condition indicated by the road condition information, the flatter, straighter and less obstacle-filled the road is. Sending ultrasonic information on this road does not require strong diffraction ability, and the diffraction ability of ultrasonic waves is negatively correlated with its own ultrasonic frequency. Therefore, the road condition information is negatively correlated with the diffraction ability of ultrasonic waves, and positively linearly correlated with the ultrasonic frequency, that is, the better the road condition, the smaller the ultrasonic frequency.

[0106] According to the technical solution provided in the embodiment of the present application, by setting the first corresponding relationship, the second corresponding relationship and the third corresponding relationship, a basis is provided for the subsequent setting of the ultrasonic information corresponding to the sound wave sending period, sound wave severity and ultrasonic frequency in various application scenarios and test scenarios.

[0107] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0108] The following is an embodiment of the device of the present application, which can be used to execute the embodiment of the method of the present application.
