[0029] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and cannot be understood as a limitation of the present disclosure.

[0030] In the implementation, if there are too many road vehicles, the opposite vehicle may not be able to distinguish whether it is the alarmed vehicle when the horn alarm is performed, resulting in misjudgment, inappropriateness, etc. Consequences will cause great hidden dangers to traffic safety and vehicle driving safety, at the same time, the horn alarm will also produce noise pollution, affecting the driving experience of the driver.

[0031] Figure 1A schematic diagram of an exemplary embodiment of a vehicle alarm method proposed in the present disclosure is shown in FIG. 1, which comprises the following steps: Figure 1

[0032] S101, receiving an alarm request.

[0033] In the embodiments of the present disclosure, the alarm request can be initiated by the driver of the first vehicle and received and processed by the processor of the first vehicle, and the first vehicle is the host vehicle.

[0034] As another possible case, when a traffic accident or other situation occurs, the driver can know the situation in front, at this time, the server can also generate an alarm request and issue it to the processor of the first vehicle for processing. It should be noted that the server can be a cloud server.

[0035] S102, obtaining the visual focus of the driver and determining the second vehicle according to the visual focus.

[0036] In the embodiments of the present disclosure, the second vehicle is the vehicle in front of the host vehicle that may have a risk with the host vehicle, and is the target vehicle of the alarm request.

[0037] The first vehicle can obtain the visual focus of the driver through a sensor, which can be an implementation tracking device. The device can determine the point, position or target of the glasses gaze by monitoring the activity of the glasses and obtaining the coordinates by positioning the pupil position. For example, the implementation tracking device can be a stereo vision sensor. After obtaining the visual focus data of the driver, the sensor sends the obtained data to the processor of the first vehicle for processing.

[0038] Further, the driver can have multiple visual focuses during driving. Alternatively, the second vehicle corresponding to the visual focus can be determined according to the visual focus position at the time of generating the alarm request.

[0039] Alternatively, the vehicle corresponding to the most visual focus can be determined as the second vehicle according to the distribution of the visual focus before and after the alarm request time.

[0040] S103, determining the target coordinates of the second vehicle.

[0041] In the embodiments of the present disclosure, the target coordinates of the second vehicle can be the real coordinates of the second vehicle. The real coordinates of the first vehicle can be determined according to the positioning system of the vehicle, and then the real coordinates of the second vehicle can be determined according to the relative position of the first vehicle and the second vehicle. For example, the target coordinates of the second vehicle can be (121.43312, 34.50224).

[0042] ​Optionally, a three-dimensional coordinate system can be established with the first vehicle as the origin and the driving direction of the vehicle as the X axis, and the target coordinates of the second vehicle can be determined according to the relative relationship between the positions of the second vehicle and the first vehicle. For example, the target coordinates of the second vehicle can be (3, 4).

[0043] In S104, the alarm request is sent to the second vehicle based on the target coordinates.

[0044] In the embodiments of the present disclosure, the transmitter can be installed on the vehicle, and the soundless transmission can be realized through the transmitter to avoid noise pollution to the environment.

[0045] To accurately send the alarm request to the second vehicle, the first vehicle can adjust the transmission direction of the transmitter according to the target coordinates, so that the transmission direction faces the second vehicle, thereby improving the success rate of the second vehicle receiving the alarm request.

[0046] In the embodiments of the present disclosure, the alarm request is first received, then the visual focus of the driver is obtained, the second vehicle is determined according to the visual focus, the target coordinates of the second vehicle are determined, and finally the alarm request is sent to the second vehicle according to the target coordinates. Through the way of determining the second vehicle according to the visual focus of the driver and directionally sending the alarm request, the point-to-point soundless alarm can be realized, the accuracy of the vehicle alarm can be improved, the driving safety of the user can be improved, and the noise pollution can be reduced.

[0047] It should be noted that in the embodiments of the present disclosure, the alarm request can include the identifier of the first vehicle, the position of the first vehicle, and the request type. Among them, the alarm position of the first vehicle can be determined by the positioning system of the first vehicle, and the request type needs to be determined according to the needs of the party initiating the alarm request. For example, the request type can include requiring the other party to avoid, requiring the other party to pay attention to the driving track of the alarm vehicle, etc., which is not limited here, and needs to be set according to the actual situation.

[0048] In the above embodiments, the visual focus of the driver can also be obtained by Figure 2 Further explanation, the method comprises:

[0049] In S201, the left eye visual line of the driver and the right eye visual line of the driver are obtained.

[0050] In the embodiments of the present disclosure, the left eye visual line of the driver and the right eye visual line of the driver can be obtained through the sensor. For example, Figure 3As shown, by the sensor, according to the position of the at least two cameras for shooting the left eye and the right eye and the pupil position and iris edge of the left eye and the right eye in the eye movement image shot by the at least two cameras, the three-dimensional left eye and right eye iris edges are reconstructed, the center point and the line of sight direction of the left eye and the right eye iris are determined in the three-dimensional space, and finally the line of sight of the left eye is determined according to the center point and the line of sight direction of the left eye, and the line of sight of the right eye is determined according to the center point and the line of sight direction of the right eye.

[0051] S202, the intersection point of the line of sight of the left eye and the line of sight of the right eye is determined as the visual field focal point by elongating the line of sight of the left eye and the line of sight of the right eye.

[0052] After the line of sight of the left eye and the line of sight of the right eye are obtained, the visual field focal point can be determined by converting the line of sight of the left eye to the same world coordinate and then the focal point of the extension line of the line of sight of the left eye and the line of sight of the right eye.

[0053] In the embodiment of the present disclosure, the line of sight of the left eye of the driver and the line of sight of the right eye of the driver are first obtained, and then the intersection point of the line of sight of the left eye and the line of sight of the right eye is determined by elongating the line of sight of the left eye and the line of sight of the right eye. The intersection point is the visual field focal point of the driver. By tracking the line of sight of the human eye, the real-time visual field focal point of the human eye is determined, which provides a basis for subsequent determination of the second vehicle.

[0054] Further, the visual field focal point is multiple, and the second vehicle is determined according to the visual field focal point. Figure 4 Further explanation, the method comprises:

[0055] S401, determining the vehicle where the visual field focal point is as the candidate vehicle.

[0056] It can be understood that when the vehicle where the visual field focal point is the vehicle that the driver gazes at, in the embodiment of the present disclosure, the target visual field focal point in the time can be determined according to the front and rear setting time generated by the alarm request, and the vehicle corresponding to the target visual field focal point is determined as the candidate vehicle. It should be noted that the setting time can be set in advance and can be set according to the actual situation, which is not limited here.

[0057] S402, obtaining the number of visual field focal points on the candidate vehicle, and determining the candidate vehicle with the number of visual field focal points greater than the number threshold as the second vehicle.

[0058] It should be noted that in some traffic scenes, especially in some areas with complex traffic conditions, the second vehicle that the driver needs to alarm is usually multiple.

[0059] Optionally, when the second vehicle is one, the driver will gaze at the second vehicle before and after initiating the alarm request according to driving habits. Optionally, when the second vehicle is multiple, the driver will constantly switch between the multiple second vehicles before and after initiating the alarm request according to driving habits.

[0060] Therefore, we can determine the second vehicle under a complex road section or a normal road section by determining the number of visual focus points.

[0061] In the embodiments of the present disclosure, first, the vehicle where the visual focus point is located is determined as a candidate vehicle, then the number of visual focus points on the candidate vehicle is obtained, and the number of visual focus points is compared with the number threshold value. When the number of visual focus points is greater than the number threshold value, we can consider that the candidate vehicle is the second vehicle. By screening the visual focus points, the second vehicle can be accurately determined, and thus the alarm request can be more accurately sent to the second vehicle.

[0062] It should be noted that the number threshold value can be set according to the actual vehicle situation, which is not limited here.

[0063] Further, in some embodiments, the second vehicle is multiple vehicles. After obtaining the candidate vehicle, the candidate vehicle with the number of visual focus points greater than the number threshold value can be selected as the target vehicle by screening the candidate vehicle, and the alarm request can be sent to these target vehicles. It should be noted that the number threshold value can be set in advance and can be set according to actual needs.

[0064] Further, after determining the second vehicle, the alarm request can be sent to the second vehicle. In the implementation, due to the complex road conditions, there is a possibility that the non-second vehicle receives the alarm request, which will affect the normal driving of other vehicles. Therefore, we also need to encrypt the alarm request. According to the target coordinates, the alarm request can be sent to the second vehicle, and the target coordinates of the second vehicle can also be determined by Figure 5 Further explanation, the method comprises:

[0065] S501, encrypting the alarm request based on the target coordinates to generate an encrypted alarm request.

[0066] In the embodiments of the present disclosure, after determining the second vehicle, the target coordinates of the second vehicle can be determined according to the position of the second vehicle. Optionally, the real coordinates of the second vehicle can be determined according to the satellite and sent to the processor of the first vehicle for processing.

[0067] Optionally, the target coordinates of the second vehicle can also be determined according to the three-dimensional coordinate system established by the first vehicle and the relative position of the second vehicle and the first vehicle.

[0068] The alarm request is encrypted based on the target coordinates to ensure that only the second vehicle can receive the alarm request.

[0069] S502, the transmitter of the host vehicle is adjusted to direct the transmission direction towards the second vehicle according to the target coordinates.

[0070] In the embodiments of the present disclosure, the transmission direction of the transmitter can be adjusted according to the target coordinates, which can increase the success rate of the second vehicle receiving the alarm request.

[0071] S503, the encrypted alarm request is sent to the second vehicle through the transmitter.

[0072] In the embodiments of the present disclosure, the alarm request is first encrypted based on the target coordinates to generate an encrypted alarm request, then the transmitter of the host vehicle is adjusted to direct the transmission direction towards the second vehicle according to the target coordinates, and finally the encrypted alarm request is sent to the second vehicle through the transmitter. By encrypting the alarm request based on the coordinates of the second vehicle and adjusting the transmission direction of the transmitter, the success rate of the second vehicle receiving the alarm request can be improved, and other vehicles can be prevented from receiving the alarm request, thereby improving the efficiency of the alarm and the driving experience and safety of the driver.

[0073] Further, after sending the alarm request to the second vehicle according to the target coordinates, the method further includes monitoring the feedback information of the second vehicle, and generating an alarm information to alarm in response to not monitoring the feedback information within a preset time length. Thus, through the feedback information of the second vehicle, the second vehicle can be alarmed without receiving the alarm request. The driver can perform secondary alarm or horn alarm after not monitoring the feedback information within the preset time length. It should be noted that the preset time length can be set in advance and can be set according to actual needs.

[0074] In the above embodiments, after sending the alarm request to the second vehicle according to the target coordinates, the method further includes Figure 6 Further explanation, the method includes:

[0075] S601, the feedback information of the second vehicle is monitored.

[0076] In the embodiments of the present disclosure, after the first vehicle sends the alarm request to the second vehicle, the second vehicle needs to return a feedback information to inform the first vehicle if it receives successfully. Through the feedback information of the second vehicle, the second vehicle can be alarmed without receiving the alarm request.

[0077] S602, in response to not monitoring the feedback information within a preset time length, an alarm information is generated to alarm.

[0078] If the feedback information is monitored within the preset time length, the coordinate information of the first vehicle is acquired, a difference between the coordinate information of the first vehicle and the alarm coordinate is acquired, in response to the difference being less than an alarm threshold, the feedback information is verified to be successful, and in response to the difference being greater than or equal to the alarm threshold, the feedback information is verified to be unsuccessful, and alarm information is generated to perform alarm. It should be noted that the preset time length is set in advance and can be set according to actual conditions. For example, the set time length can be 0.1S.

[0079] It should be noted that when the difference between the coordinate information of the first vehicle and the alarm coordinate is less than the alarm threshold, the feedback information can be considered to be sent to the first vehicle in a targeted manner. Thus, it can be prevented that the feedback information of other vehicles is mistakenly sent to the first vehicle, causing a traffic hazard.

[0080] In the embodiment of the present disclosure, the feedback information of the second vehicle is first monitored, and then in response to the feedback information not being monitored within the preset time length, alarm information is generated to perform alarm. Thus, by judging whether the feedback information of the second vehicle is received within a fixed time, it can be judged whether the second vehicle normally receives the alarm request, so that different situations can be responded to, the accuracy of the vehicle alarm is increased, and the safety of driving is ensured. Figure 7 A schematic diagram of an exemplary embodiment of a vehicle alarm method proposed in the present disclosure is shown in FIG. 1. Figure 7 As shown in the figure, the vehicle alarm method includes the following steps:

[0081] S701, receiving an alarm request sent by a first vehicle based on a target coordinate of a second vehicle.

[0082] It should be noted that in addition to the coordinate information of the second vehicle, the alarm request can also include an alarm type, coordinate information of the first vehicle, etc. Here, no limitation is made, and the specific limitation is made according to actual needs.

[0083] In the embodiment of the present disclosure, the target vehicle of the alarm request can be the vehicle, or can be other vehicles, so it is necessary to distinguish whether the vehicle is the target vehicle.

[0084] S702, acquiring coordinate information of the second vehicle, and verifying the target coordinate based on the coordinate information of the second vehicle.

[0085] After receiving the alarm request, the coordinate information of the first vehicle and the target coordinate can be subtracted, and the difference is compared with an alarm threshold, in response to the difference being less than the alarm threshold, the alarm request is verified to be successful.

[0086] It should be noted that the alarm threshold can be set according to actual conditions, and no limitation is made here.

[0087] S703, in response to the difference between the coordinate information of the second vehicle and the target coordinate being less than the alarm threshold, the alarm request is verified, and the second vehicle is alarmed.

[0088] In the embodiments of the present disclosure, first, the alarm request sent by the first vehicle based on the target coordinate of the second vehicle is received, then the coordinate information of the second vehicle is obtained, the target coordinate is verified based on the coordinate information of the second vehicle, and finally the second vehicle is alarmed after the verification is passed. Thus, by matching the coordinate information of the vehicle and the coordinate information in the alarm request, it is determined whether the alarm request is sent to the vehicle, and directional alarm can be realized, which prevents false alarm due to misreception and increases the user experience.

[0089] It should be noted that the alarm request can include alarm information, alarm coordinates of the first vehicle, and alarm types. The processor of the second vehicle can obtain the alarm coordinates of the first vehicle according to the alarm request to generate feedback information, and adjust the emission direction of the emitter of the second vehicle to the first vehicle according to the alarm coordinates, and finally send the feedback information to the first vehicle through the emitter.

[0090] According to the alarm coordinates, the emission direction of the emitter of the second vehicle is adjusted, which can make the signal wave propagate to the first vehicle as much as possible, increase the success rate of the first vehicle receiving the feedback information, and thus prevent repeated alarm or horn from sounding due to the first vehicle failing to successfully receive the feedback information.

[0091] It should be noted that the feedback information is used to feed back the result of the second vehicle successfully receiving the alarm request to the first vehicle, so that after the alarm request is received and verified, the feedback information can be generated and sent to the first vehicle.
