Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified.

In the embodiment of the application, V2X is called vehicle to updating throughout english, and chinese explains that the vehicle communicates with other devices, which may also be called vehicle wireless communication technology. V2X is a new generation of information communication technology that connects vehicles with everything. C-V2X is a cellular technology-based V2X, which is a communication technology based on the 3rd generation partnership project (3 GPP) global unified standard, or a vehicular wireless communication technology formed by the evolution of 3G/4G/5G cellular network communication technologies. For example, C-V2X may include Long Term Evolution (LTE) -V2X and 5G-V2X, LTE-V2X supporting a smooth evolution to 5G-V2X from a technology evolution perspective. The method provided by the embodiment of the application can be applied to V2X based on any cellular (such as 3G/4G/5G, and the next generation cellular communication technology). In other embodiments, the method provided by the embodiment of the present application may also be applied to V2X based on wireless fidelity (WIFI), Universal Serial Bus (USB), and other technologies.

Wherein V represents a vehicle and X represents any object that interacts with the vehicle. Currently, X mainly includes vehicles, people (or pedestrian devices), road infrastructure (or road side units, which are hardware units that are disposed at the roadside and can implement V2X communication and support V2X applications), and network.

The information interaction outlined by V2X (or C-V2X) may include: the interaction between vehicles (V2V), the interaction between vehicles and people (V2P), the interaction between vehicles and roadside units (V2I), and the interaction between vehicles and networks (V2N). In addition, the C-V2X comprises two communication interfaces, namely a short-distance direct communication interface (such as a PC5 interface) between a vehicle, a person and road basic equipment, and a communication interface (such as a Uu interface) between the vehicle and a network (such as a base station), and can realize reliable communication in a long distance and a larger range.

The embodiment of the application provides a whistle method, and vehicle-mounted equipment can broadcast a first V2X message, wherein the first V2X message comprises an ID of the vehicle-mounted equipment and position information of a vehicle where the vehicle-mounted equipment is located. Of course, the vehicle-mounted device may also receive the first V2X message broadcast by other vehicle-mounted devices. For example, a first in-vehicle device may receive a plurality of first V2X messages broadcast by a plurality of second in-vehicle devices. Then, the first vehicle-mounted device may compare the current position information of the vehicle where the first vehicle-mounted device is located with the position information in the plurality of first V2X messages, and determine, from the plurality of second vehicle-mounted devices, N third vehicle-mounted devices that are located in front of the vehicle where the first vehicle-mounted device is located and closest to the first vehicle-mounted device, and that have the same traveling direction as the vehicle where the first vehicle-mounted device is located; finally, in response to the whistle operation of the user, the first vehicle-mounted device may send a second V2X message to the N third vehicle-mounted devices to request the N third vehicle-mounted devices to play the whistle prompt.

Compared with the conventional scheme, in the embodiment of the application, the first vehicle-mounted device requests other vehicle-mounted devices to play the whistle prompt through the second V2X message, instead of the vehicle where the first vehicle-mounted device is located using the high-frequency horn to make the whistle. Thus, noise damage to people around the whistling vehicle can be reduced, and noise pollution can be reduced.

The N third vehicle-mounted devices are N vehicle-mounted devices which are located in the same direction as the first vehicle-mounted device, are located in front of the vehicle where the first vehicle-mounted device is located, and are closest to the first vehicle-mounted device. Namely, the vehicle where the N third vehicle-mounted devices are located is a vehicle which may influence the normal running of the vehicle where the first vehicle-mounted device is located. Generally, the whistle prompt sent by the vehicle where the first vehicle-mounted device is located is used for reminding the vehicles of avoiding. Therefore, in the embodiment of the application, the first vehicle-mounted device sends the second V2X message to the N third vehicle-mounted devices in a targeted manner to request the N third vehicle-mounted devices to play the whistle prompt, so that noise damage to people around the vehicle can be reduced, and noise pollution is reduced.

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

Please refer to fig. 1, which is a schematic view of an application scenario in an embodiment of the present application. As shown in fig. 1, the vehicle 2, and the vehicle 3 are all vehicles traveling in a first direction (rightward direction as shown in the drawing); the vehicle 4, the vehicle 5, and the vehicle 6 are all vehicles that travel in the second direction (leftward direction as shown). Wherein each vehicle includes an in-vehicle device therein, and the in-vehicle devices in the respective vehicles can perform V2X communication. For example, the onboard devices of vehicle 1, vehicle 2, vehicle 3, vehicle 4, vehicle 5, and vehicle 6 may all broadcast a first V2X message. Taking the first V2X message broadcast by the in-vehicle device of the vehicle 5 as an example, the first V2X message includes the ID of the in-vehicle device of the vehicle 5 and the location information of the vehicle 5. The onboard devices in vehicle 1, vehicle 2, vehicle 3, vehicle 4, and vehicle 6 may all receive the first V2X message broadcast by vehicle 1. Similarly, the on-board device in the vehicle 5 may also receive the first V2X message broadcast by another vehicle.

For example, an in-vehicle device in the vehicle 5 requests an in-vehicle device in another vehicle to play a whistle note. Assume that the in-vehicle devices of vehicle 5 can receive the first V2X message broadcast by the in-vehicle devices of vehicle 2, vehicle 3, vehicle 4, and vehicle 6. Since the vehicle 5 is far from the vehicle 1, the vehicle-mounted device of the vehicle 5 cannot receive the first V2X message broadcast by the vehicle-mounted device of the vehicle 1.

The in-vehicle device in the vehicle 5 may receive a whistling operation by the user. In response to the whistle operation, the on-board devices in the vehicle 5 may determine, according to the received first V2X message (e.g., the first V2X message broadcast by the on-board devices of the vehicles 2, 3, 4, and 6), and the position of the vehicle 5, that the vehicles corresponding to 2 (i.e., N is 2) third on-board devices that are the same as the traveling direction of the own vehicle 5, are located ahead of the traveling direction of the vehicle 5, and are closest to the on-board devices of the vehicle 5 are the vehicles 4 and 6. The onboard apparatus of vehicle 5 may send a second V2X message to the onboard apparatuses of vehicle 4 and vehicle 6 to request the onboard apparatuses of vehicles 4 and 6 to issue whistle alerts.

For example, the vehicle-mounted device of the vehicle (such as the vehicle 5) may execute the method of the embodiment of the present application in a scenario that requests the vehicle-mounted device in another vehicle to play the whistle prompt.

Scene 1: the vehicle 5 is traveling on a road where whistling is prohibited.

It can be understood that when the vehicle 5 runs on a road on which whistling is prohibited, the driver cannot remind other surrounding vehicles to avoid by controlling the whistling mode of the vehicle 5. Under the condition, the method of the embodiment of the application can achieve the aim of reminding surrounding vehicles to avoid without requiring the vehicles 5 to whistle, and meets the driving standard on the road with the whistle forbidden.

Here, road infrastructure devices may be disposed around each road, and these road infrastructure devices may broadcast a V2X message (referred to as a third V2X message). The third V2X message includes road information of the current road segment. For example, the road information may include a location, a number, a road type (e.g., national road, provincial road, urban road, or prefecture road), and a road segment type (e.g., a section in which whistling is prohibited, a section in which school is located, a section in which office is located, a section in which residential district is located, or a section in which downtown district is located, etc.) of the current road. The in-vehicle device of the vehicle 5 may receive the third V2X message described above, and determine that the vehicle 5 is currently running on the road on which the whistle is prohibited according to the third V2X message.

Alternatively, the in-vehicle device of the vehicle 5 may periodically acquire the position information of the vehicle 5. For example, the vehicle-mounted device of the vehicle 5 may acquire the position information of the vehicle 5 by Global Positioning System (GPS) Positioning. Then, the in-vehicle device of the vehicle 5 may determine that the vehicle 5 is currently running on the whistle-prohibited road based on the above-described position information.

Scene 2: when the vehicle 5 is traveling on a road in an downtown area.

It can be understood that when the vehicle 5 is running on a road in an urban area, if the driver wants to whistle by the vehicle 5, the driver can remind other vehicles around to avoid the road. The downtown area is loud, and the whistle issued by the vehicle 5 may not be noticeable to the drivers of the surrounding vehicles. In this case, the method of the embodiment of the present application is performed, and the purpose of reminding the driver of the surrounding vehicle of avoiding can be achieved without the vehicle 5 whistling.

The vehicle-mounted device of the vehicle 5 may receive the third V2X message, and determine that the vehicle 5 is currently driving on the road in the downtown area according to the third V2X message. Alternatively, the in-vehicle device of the vehicle 5 may determine that the vehicle 5 is currently traveling on the road in the downtown area from the position information of the vehicle 5.

Scene 3: the vehicle 5 travels on roads in schools, offices, and residential areas.

It is understood that when the vehicle 5 travels on a school road, an office road, or a residential road, noise generated by the whistle of the vehicle interferes with the learning, work, or rest of other people. Under the condition, the method of the embodiment of the application can achieve the aim of reminding surrounding vehicles to avoid without the need of whistling the vehicles 5, and can not cause noise damage to people in surrounding schools, office areas or residential areas.

The vehicle-mounted device of the vehicle 5 may receive the third V2X message, and determine that the vehicle 5 is currently driving on a school road, an office road, or a residential road according to the V2X message. Alternatively, the in-vehicle device of the vehicle 5 may determine that the vehicle 5 is currently traveling on a road of a school, a road of an office area, or a road of a residential area, based on the position information of the vehicle 5.

Scene 4: the vehicle 5 is traveling on the downtown road at night (e.g., 10: 00 evening-4: 00 early morning).

It will be appreciated that during nighttime hours (e.g., 10: 00 pm-4: 00 am) the person is resting. Residential districts may be arranged on two sides of a road in the urban area, and if the vehicles 5 make whistle, rest of residents in the urban area can be affected, and noise damage is caused to the residents in the urban area. Under the condition, the method of the embodiment of the application can be executed, and the aim of reminding surrounding vehicles to avoid can be achieved without the need of whistling the vehicles 5. Even if the vehicle 5 runs on the urban street at night, it does not cause noise damage to residents in the residential area on the roadside of the urban street.

The methods in the following embodiments may be implemented in an in-vehicle device having the above-described hardware structure.

Please refer to fig. 3, which is a flowchart illustrating a whistle method according to an embodiment of the present application. In the embodiment of the present application, a whistle method provided in the embodiment of the present application is described by taking as an example that a first vehicle-mounted device is a vehicle-mounted device of a vehicle 5, and a plurality of second vehicle-mounted devices include vehicle-mounted devices of a vehicle 1, a vehicle 2, a vehicle 3, a vehicle 4, and a vehicle 6. As shown in fig. 3, the method may include S301-S306.

S301: the in-vehicle device of the vehicle 5 periodically acquires the current position information of the vehicle 5.

For example, the vehicle-mounted device of the vehicle 5 may acquire the current position information of the vehicle 5 by GPS positioning. For another example, the vehicle-mounted device of the vehicle 5 may receive the third V2X message broadcast by the road infrastructure device, and determine the current location information of the vehicle 5 according to the road information in the third V2X message. For a detailed description of the road information in the third V2X message, reference may be made to the description in the foregoing embodiments, which are not repeated herein.

For example, the period in which the vehicle-mounted device of the vehicle 5 acquires the current position information of the vehicle 5 may be any length of time such as 30 seconds, 1 minute, 3 minutes, or 5 minutes.

S302: the onboard devices of each of vehicle 1, vehicle 2, vehicle 3, vehicle 4, vehicle 5, and vehicle 6 broadcast a first V2X message.

It is understood that the onboard device of each vehicle may broadcast a first V2X message; however, the ID and the location information of the vehicle-mounted device included in the first V2X message broadcast by each vehicle-mounted device are different. For example, the first V2X message broadcast by the vehicle-mounted device of the vehicle 1 includes: ID of the in-vehicle device of the vehicle 1 and position information of the vehicle 1; the first V2X message broadcast by the onboard device of the vehicle 3 includes: the ID of the in-vehicle device of the vehicle 3 and the position information of the vehicle 3.

Although the on-board device of each vehicle may broadcast the first V2X message; however, the distance of the vehicle 5 from different vehicles is different; thus, the onboard device of vehicle 5 may only receive a portion of the onboard device broadcast first V2X message. For example, due to the large distance between the vehicle 1 and the vehicle 5 shown in fig. 1, the vehicle-mounted device of the vehicle 5 cannot receive the first V2X message broadcast by the vehicle-mounted device of the vehicle 1. The distances between other vehicles (such as vehicle 2, vehicle 3, vehicle 4, and vehicle 6) and vehicle 5 are small, and vehicle 5 may receive the first V2X message broadcast by the onboard devices of vehicle 2, vehicle 3, vehicle 4, and vehicle 6. The method of the embodiment of the present application further includes S303.

S303: the onboard device of vehicle 5 receives the first V2X message broadcast by vehicles 2, 3, 4, and 6.

Each first V2X message includes an identification ID of the corresponding vehicle-mounted device and location information of the vehicle. The in-vehicle device of the vehicle 5 may store the information in the received first V2X message after receiving the plurality of first V2X message information.

For example, table 1 is an example of a first vehicle information table provided in the embodiment of the present application. As shown in table 1, the first vehicle information table includes the ID and the location information in the first V2X message received by the vehicle 5.

TABLE 1

For example, the first V2X message may also include directional information of the vehicle. For example, the first V2X message broadcast by the vehicle-mounted device of the vehicle 5 may further include: the traveling direction of the vehicle 5 is the second direction (leftward direction in the figure) of the traveling direction of the vehicle 5. The first V2X message broadcast by the vehicle-mounted device of the vehicle 2 may further include: the traveling direction of the vehicle 2 is a first direction (rightward direction in the figure) of the traveling direction of the vehicle 2. For example, the first vehicle information table shown in table 1 may be replaced with the first vehicle information table shown in table 2.

Table 2:

s304: the vehicle-mounted device of the vehicle 5 compares the position information in the received first V2X messages with the current position information of the vehicle-mounted device of the vehicle 5, and determines N third vehicle-mounted devices (the vehicle-mounted devices of the vehicle 4 and the vehicle 6).

The driving direction of the vehicle where the third vehicle-mounted device is located is the same as the driving direction of the vehicle where the first vehicle-mounted device is located, and the third vehicle-mounted device is the vehicle-mounted device which is closest to the first vehicle-mounted device in the plurality of second vehicle-mounted devices. Wherein, the number of the third vehicle-mounted devices can be one, two or three, etc.

For example, as shown in fig. 1 or table 2, the traveling direction of the vehicle 5 is the same as the traveling directions of the vehicles 3, 4, and 6. As shown in fig. 1, the traveling directions of the vehicle 3, the vehicle 4, and the vehicle 6 are located in front of the vehicle 5. Alternatively, from the position information of the vehicle 3, the vehicle 4, and the vehicle 6 shown in table 2, it can be determined that the traveling directions of the vehicle 3, the vehicle 4, and the vehicle 6 are located in front of the vehicle 5.

Assuming that N is 2, the in-vehicle device of the vehicle 5 can determine that the vehicles corresponding to the 2 third in-vehicle devices closest to the vehicle 5 are the vehicle 4 and the vehicle 6 from the position information of the vehicle 3, the vehicle 4, and the vehicle 6 shown in fig. 1 or table 2. Assuming that N is 3, the in-vehicle device of the vehicle 5 can determine that the vehicles corresponding to the 2 third in-vehicle devices closest to the vehicle 5 are the vehicle 3, the vehicle 4, and the vehicle 6 from the position information of the vehicle 3, the vehicle 4, and the vehicle 6 shown in fig. 1 or table 2.

In the following embodiment, the method according to the embodiment of the present application is described by taking N as 2 and taking the vehicles corresponding to the N third vehicle-mounted devices as the vehicle 4 and the vehicle 6 as examples.

The second vehicle information table may be preset in the in-vehicle device of the vehicle 5. As shown in table 3, the second vehicle information table includes information of the N third vehicle-mounted devices.

TABLE 3

It is understood that the information in table 4 may be updated each time the on-board device of vehicle 5 updates the current location information. Or, the vehicle-mounted device of the vehicle 5 detects that the position change of the vehicle meets the preset condition, and updates the information in the table 4.

For example, the preset condition is that the vehicle 1 travels a route of 100 meters, or the preset condition is that time passes 5 minutes or the like. That is, the vehicle 5 detects that the own vehicle has traveled the distance of 100 meters, or the vehicle 5 determines that 5 minutes have elapsed from the time when the table 4 was last updated. The vehicle 5 acquires its own location information and receives a first V2X message broadcast by surrounding vehicles. And updating the vehicle information in the vehicle information storage table according to the current position information and the first V2X message.

S305: in response to the user's whistle operation, the in-vehicle device of the vehicle 5 transmits the second V2X message to the in-vehicle devices of the vehicles 4 and 6.

Therein, the on-board device of the vehicle 5 may broadcast a second V2X message. The second V2X message is used to request the in-vehicle devices of vehicles 4 and 6 to play a whistling cue. The second V2X message includes the IDs of the in-vehicle devices of the vehicle 4 and the vehicle 6. Thus, after the vehicle-mounted devices of the vehicles 4 and 6 receive the second V2X message, a whistling prompt can be played; and the vehicle-mounted devices of other vehicles (such as the vehicle 2 or the vehicle 3) receive the second V2X message, and the second V2X message can be discarded because the second V2X message does not include the ID of the vehicle-mounted device of the vehicle.

For example, as shown in table 4, a data structure schematic table of a second V2X message provided for the embodiment of the present application:

TABLE 4

For example, the IDs of the vehicle-mounted devices of the vehicles 4 and 6 may be the destination addresses of the second V2X message. The IDs of the in-vehicle devices of the vehicles 4 and 6 may be carried in the "destination address" field of the second V2X message shown in table 4.

For example, a whistling button may be provided on the vehicle-mounted device of the vehicle. The whistling operation may be a click operation of the whistling button by the user. The whistle key can be a physical key or a whistle option on a display screen of the vehicle-mounted device.

Alternatively, the whistling operation may be that the vehicle-mounted device receives a voice command of the user, and the voice command is used for indicating the vehicle to whistling. For example, the voice command may be "whistling".

S306: the in-vehicle devices of the vehicles 4 and 6 receive the second V2X message, and in response to the second V2X message, the in-vehicle devices of the vehicles 4 and 6 play a whistling cue.

After the in-vehicle devices of the vehicle 5 request the in-vehicle devices of the vehicle 4 and the vehicle 6 to play the whistle prompt in response to the whistle operation by the user, the in-vehicle devices of the vehicle 5 may also determine whether the road on which the vehicle 5 is currently traveling allows whistle with a high-frequency horn. If the road on which the vehicle 5 is currently traveling allows for whistling by high frequency horns, the vehicle 5 may be whistling by high frequency horns. If the road on which the vehicle 5 is currently traveling does not allow whistling by the high frequency horn, the vehicle 5 will not whistling by the high frequency horn.

Compared with the conventional scheme, in the embodiment of the application, the vehicle-mounted device of the vehicle 5 requests other vehicle-mounted devices to play the whistle prompt through the second V2X message instead of the vehicle 5 sending out the whistle by using a high-frequency horn. Thus, noise damage to people around the whistling vehicle can be reduced, and noise pollution can be reduced.

The vehicles 4 and 6 are 2 vehicles which are located in front of the vehicle 5 and closest to the vehicle 5 in the same traveling direction as the vehicle 5. I.e., vehicle 4 and vehicle 6, are vehicles that may affect the normal operation of vehicle 5. Generally speaking, the whistle alerts of the vehicles 5 are intended to alert them to avoid. Therefore, in the embodiment of the present application, the vehicle-mounted device of the vehicle 5 specifically sends the second V2X message to the vehicle-mounted devices of the vehicles 4 and 6 to request the vehicle-mounted devices of the vehicles 4 and 6 to play the whistle prompt, so that noise damage to people around the vehicle can be reduced, and noise pollution can be reduced.

In one possible embodiment, after the in-vehicle device of the vehicle 4 and the in-vehicle device of the vehicle 6 play the whistle prompt, the position of the vehicle 5 relative to the own vehicle may also be displayed on the display screen of the in-vehicle devices.

For example, taking the display screen on the in-vehicle device of the vehicle 4 as an example, the display interface of the in-vehicle device display is as shown in fig. 4, the distance between the vehicle 4 and the vehicle 5 is 50 meters, the vehicle 5 is located right behind the vehicle 4, and the display screen of the vehicle 4 includes the vehicle 5 and the vehicle 4.

Illustratively, the S304 may include S304a-S304 d. For example, as shown in FIG. 5, S304 shown in FIG. 3 may include S304a-S304 d.

S304 a: the in-vehicle device of the vehicle 5 determines the traveling direction of the vehicle 5 from the current position.

It should be noted that S304a-S304d in the embodiment of the present application are specific implementations of S304 in the above embodiment, and details related to S304 may be applied to the embodiment of the present application, and are not described herein again in order to reduce repetition. In addition, the method in the embodiment of the present application may also be applied to S304 described above.

S304 b: the vehicle-mounted device of the vehicle 5 determines the traveling directions of the vehicle 2, the vehicle 3, the vehicle 4, and the vehicle 6 based on the position information in the plurality of first V2X messages.

For example, the vehicle-mounted device of the vehicle 5 may determine the driving direction of the vehicle in which the vehicle-mounted device is located according to the position information in the first V2X message.

For another example, the vehicle-mounted device of the vehicle 5 may determine the traveling direction of the vehicle in which the vehicle-mounted device is located, based on the change in the position information in two consecutive first V2X of the same vehicle-mounted device.

S304 c: the on-board devices of the vehicles 5 respectively calculate the distance between each vehicle and the vehicle 5 according to the current position and the position information in the plurality of first V2X messages.

It is understood that by executing step S304b, the traveling direction of vehicle 2 is opposite to the traveling direction of vehicle 5, and the traveling directions of vehicles 3, 4, and 6 are the same as the traveling direction of vehicle 5. A vehicle in the opposite direction of travel to vehicle 5 does not affect the driving of vehicle 5 and vehicle 2 is not on the same side of the road as vehicle 5. The in-vehicle device of the vehicle 5 may calculate a distance value between the vehicle and the vehicle 5 in the same direction as the traveling direction of the vehicle 5.

The vehicle-mounted device of the vehicle 5 may calculate the distance between the vehicle 3 and the vehicle 5 according to the position information in the first V2X message. Alternatively, the in-vehicle device of the vehicle 5 may also acquire the distance between the vehicle 3 and the vehicle 5 by a distance sensor.

For example, vehicle 5 calculates that the distance between vehicle 3 and vehicle 5 is 100 meters, the distance between vehicle 4 and vehicle is 50 meters, and the distance between vehicle 6 and vehicle 5 is 50 meters.

S304 d: the vehicle 5 determines, from among the vehicles 2, 3, 4, and 6, the vehicles that are the same as the traveling direction of the vehicle 5, are ahead of the traveling direction of the vehicle 5, and are the closest to the vehicle 5, as the vehicles 4 and 6.

As shown in fig. 1 or table 2, the traveling direction of the vehicle 5 is the same as the traveling directions of the vehicles 3, 4, and 6. As shown in fig. 1, the traveling directions of the vehicle 3, the vehicle 4, and the vehicle 6 are located in front of the vehicle 5. The on-board device of the vehicle 5 determines the distance of the vehicles 4 and 6 from the vehicle 5 to be the closest according to the distances between the vehicle 5 and the vehicles 3, 4 and 6.

By adopting the method in the embodiment of the present application, the vehicle-mounted device of the vehicle 5 can gradually determine the vehicle which is the same as the driving direction of the vehicle 5, is ahead of the driving direction of the vehicle 5, and is closest to the vehicle 5. The vehicle 5 can have a pointed prompt effect for drivers of surrounding vehicles, noise damage to people around the whistling vehicle can be reduced, and noise pollution is reduced.
