[0024] The detailed description of the present disclosure will be described below with reference to the accompanying drawings. It should be understood that the detailed description described herein is only used to explain and describe the present disclosure, and is not intended to limit the present disclosure.

[0025] In recent years, with the development of Internet of Vehicles technology, vehicles can establish an ad hoc network through wireless communication to realize information interaction and cooperation, providing a new solution for improving driving safety.

[0026] As described in the background, in a traffic environment, the related art usually establishes communication between vehicles to realize information interaction and cooperation between vehicles, which cannot meet the comprehensive and timely safety warning needs.

[0027] Therefore, the embodiments of the present disclosure provide a communication method, a storage medium, a mobile terminal and a computer program product to solve the problems in the related art, which can exchange information between different types of mobile terminals through an ad hoc network, such as a vehicle terminal and a mobile terminal, to realize cooperative communication between heterogeneous mobile terminals, thereby improving the comprehensiveness and reliability of safety warning.

[0028] FIG. 1 is a flowchart of a communication method according to an exemplary embodiment of the present disclosure. Referring to FIG. 1, the communication method can include the following steps:

[0029] Step S101, a first mobile terminal determines an ad hoc network centered on the first mobile terminal, the ad hoc network including at least one second mobile terminal, the first mobile terminal and the second mobile terminal being different in type;

[0030] Step S102, the first mobile terminal sends a message to the second mobile terminal or receives a message from the second mobile terminal.

[0031] Optionally, the type of the first mobile terminal is a vehicle terminal, and the type of the second mobile terminal is a handheld terminal; or,

[0032] The type of the second mobile terminal is a vehicle terminal, and the type of the first mobile terminal is a handheld terminal.

[0033] It should be understood that the mobile terminals can communicate with each other through V2X (Vehicle to Everything) communication. V2X communication is a technology that allows vehicles to communicate with any entity in their environment, including other vehicles, pedestrians, etc., which can be achieved through wireless communication technologies such as LTE, 5G, Wi-Fi, etc.

[0034] It should be understood that the vehicle terminal can be a comprehensive device system for vehicle information collection, communication and processing, including a screen, a controller, a communication module and other hardware components. The vehicle terminal can collect its own operating parameters and interact with other mobile terminals to provide basic data support for safety warning and other applications.

[0035] For example, the handheld terminal can be a smartphone connected to a GPS system.

[0036] For example, in a traffic scenario involving pedestrians and vehicles, the first mobile terminal can be a vehicle-mounted terminal representing a vehicle, and the second mobile terminal can be a handheld terminal representing a pedestrian. In the self-organizing network centered on the first mobile terminal, there can be vehicle-mounted terminals of the same type as the first mobile terminal, or second mobile terminals of a different type from the first mobile terminal, i.e., handheld terminals. The first mobile terminal can send messages to the second mobile terminal or receive messages from the second mobile terminal, and can also interact with mobile terminals of the same type as the first mobile terminal, thereby achieving information exchange between vehicles and pedestrians, and between vehicles.

[0037] In the foregoing manner, the first mobile terminal determines a self-organizing network centered on the first mobile terminal, the self-organizing network including at least one second mobile terminal, the first mobile terminal being of a different type from the second mobile terminal. The first mobile terminal sends messages to the second mobile terminal or receives messages from the second mobile terminal. Information exchange between different types of mobile terminals, such as vehicle-mounted terminals and mobile terminals, can be achieved through the self-organizing network, thereby enabling cooperative communication between heterogeneous mobile terminals, and improving the comprehensiveness and reliability of safety warnings.

[0038] In a possible implementation, the range of the self-organizing network can be determined in the following manner:

[0039] The first mobile terminal acquires motion state information of mobile terminals within its communication range;

[0040] The first mobile terminal determines the range of the self-organizing network according to the motion state information and the motion state of the first mobile terminal itself.

[0041] In the foregoing manner, the range of the self-organizing network is dynamically determined according to the motion states of the mobile terminals, which can better adapt to the actual motion state of a vehicle, thereby improving the stability and reliability of information transmission.

[0042] In a possible implementation, the first mobile terminal determines the range of the self-organizing network according to the motion state information and the motion state of the first mobile terminal itself, including:

[0043] The first mobile terminal determines a safe distance between the first mobile terminal and each other mobile terminal within its communication range according to the motion state information and the motion state of the first mobile terminal itself.

[0044] The first mobile terminal determines the range of the self-organizing network according to the safe distance between the first mobile terminal and each other mobile terminal within its communication range.

[0045] By the above manner, the self-organizing network range determined based on the safety distance can be dynamically adjusted according to the motion state information of the mobile terminal, thereby better adapting to different traffic scenarios and traffic density changes, improving the adaptability and flexibility of the self-organizing network. Moreover, the reliability of communication can be improved, and stable communication connection can be ensured within the self-organizing network range. Thus, the self-organizing network is more reasonable in terms of construction, avoiding the mobile terminal from processing too much communication information, and ensuring that other terminals with safety hazards are not missed.

[0046] In a possible implementation, the first mobile terminal is a vehicle terminal, and the other mobile terminal is a vehicle terminal.

[0047] The safety distance is determined by the first mobile terminal according to the speed information and acceleration information of the other mobile terminal and the motion state of the first mobile terminal itself.

[0048] It should be understood that the position information of each mobile terminal can obtain the latitude and longitude coordinates of itself by using a global positioning system (GPS) or other positioning technology. By comparing these coordinates, the relative position relationship between the vehicle terminal and the other mobile terminal can be determined.

[0049] It should also be understood that by analyzing and comparing the position information, the front and rear vehicles driving on the same lane can be determined, wherein the first mobile terminal can be a vehicle terminal of the front vehicle or a vehicle terminal of the rear vehicle.

[0050] For example, the safety distance between the front and rear vehicles can be obtained according to the following calculation formula (1):

[0051] wherein D is the safety distance, V f is the speed of the vehicle where the front vehicle terminal is located, V r is the speed of the vehicle where the rear vehicle terminal is located, a f is the acceleration of the vehicle where the front vehicle terminal is located, a r-max is the maximum braking deceleration of the vehicle where the rear vehicle terminal is located, T r-d and T r-b are the control delay time and the driver's control lag time of the braking system of the vehicle where the rear vehicle terminal is located, respectively, and d0 is a preset static safety distance.

[0052] It should be understood that the maximum braking deceleration of the vehicle is related to the road adhesion. Different road conditions (such as dry, wet, muddy, etc.) will affect the road adhesion. For example, on a dry road, the road adhesion is relatively high, and the vehicle can generate a larger braking deceleration, while on a wet or muddy road, the road adhesion is reduced, and the braking deceleration of the vehicle will be correspondingly reduced.

[0053] It should also be understood that the driver can select a suitable preset static safety distance according to the vehicle speed, road conditions, etc. and make appropriate adjustments according to the actual road conditions and driving conditions.

[0054] In the above manner, the safety distance between the vehicle terminals can be determined according to the motion state of each terminal and in combination with the related calculation formula, so that the actual state of the vehicle can be more in line with the actual state of the vehicle, and the reliability of communication can be improved.

[0055] In one possible implementation, the type of the first mobile terminal is a vehicle terminal, and the type of the other mobile terminal is a handheld terminal.

[0056] The safety distance is determined by the first mobile terminal according to the speed information and acceleration information of the first mobile terminal.

[0057] For example, the safety distance can be obtained according to the following calculation formula (2):

[0058] where D is the safety distance, V is the speed of the vehicle in which the vehicle terminal is located, a max is the maximum braking deceleration of the vehicle in which the vehicle terminal is located, T d and T b are the control lag time of the braking system and the control lag time of the driver of the vehicle in which the vehicle terminal is located, respectively.

[0059] In another possible implementation, the type of the first mobile terminal is a handheld terminal, and the type of the other mobile terminal is a vehicle terminal.

[0060] The safety distance is determined by the first mobile terminal according to the speed information and acceleration information of the other mobile terminal.

[0061] It should be noted that when the type of the first mobile terminal is a handheld terminal and the type of the other mobile terminal is a vehicle terminal, the safety distance between the two can also be calculated using the above calculation formula (2).

[0062] In the above manner, the safety distance between the vehicle terminal and the handheld terminal can be determined according to the motion state of the vehicle terminal and the related calculation formula, so that the actual scene can be more in line with the actual scene, and the reliability of communication can be improved.

[0063] In one possible implementation, the first mobile terminal determines the range of the ad hoc network according to the safety distance between the first mobile terminal and each other mobile terminal within the communication range of the first mobile terminal, which can include:

[0064] The safety distance is corrected according to at least one of the current road traffic, the road type, the surrounding crowd, the road adhesion, and the weather conditions.

[0065] The range of the ad hoc network is determined according to the modified safety distance.

[0066] It should be understood that in the case of high traffic flow, narrow road, dense crowd, wet and icy road surface or heavy rain, heavy fog and other bad weather, the safety distance needs to be appropriately increased, and the range of the ad hoc network will also be expanded. In the case of low traffic flow, wide road, sparse crowd, good road adhesion or fine weather, the range of the ad hoc network can be relatively small to improve the network performance. That is, in the above possible implementation manner, the safety distance can be adaptively scaled according to at least one of the current road traffic flow, road type, surrounding crowd, road adhesion and weather condition, improving the flexibility of the range of the ad hoc network. It is worth noting that in an example, the modified safety distance should not be less than the minimum safety distance, which can be the minimum value among the safety distances between the first mobile terminal and each other mobile terminal within the communication range thereof respectively.

[0067] In the above manner, the range of the ad hoc network is adjusted according to the safety distance and combined with the actual traffic environment changes, which can meet the specific safety requirements in different scenarios and help to improve the comprehensiveness and reliability of communication.

[0068] In a possible implementation manner, the method can further include:

[0069] When it is determined that the first mobile terminal meets the safety warning condition, the first mobile terminal sends the warning prompt information to at least one second mobile terminal.

[0070] In the above manner, when the safety hazard is detected, the warning prompt information can be sent to the other mobile terminals within the range of the ad hoc network, so as to effectively reduce the risk of traffic accidents.

[0071] In a possible implementation manner, when it is determined that the first mobile terminal meets the safety warning condition, the first mobile terminal sends the warning prompt information to at least one second mobile terminal, which can include:

[0072] According to the motion state of the first mobile terminal and the motion state of the at least one second mobile terminal, it is determined whether the first mobile terminal has a collision risk;

[0073] When it is determined that the first mobile terminal has a collision risk with any second mobile terminal, the first mobile terminal sends the warning prompt information to the second mobile terminal having the collision risk.

[0074] For example, according to the motion state of the first mobile terminal and the motion state of the at least one second mobile terminal, whether there is a collision risk can be determined, for example, in terms of an objective safety distance based on a motion trajectory, a subjective safety distance based on driving behavior and pedestrian behavior, and an accidental safety distance caused by a vehicle out of control.

[0075] In this way, whether there is a collision risk can be determined according to the motion state of each mobile terminal, and warning prompt information can be sent to the corresponding mobile terminal, thereby improving the comprehensiveness and reliability of safety warning.

[0076] In a possible implementation, when it is determined that the first mobile terminal meets the safety warning condition, the first mobile terminal can send warning prompt information to the at least one second mobile terminal, which can include:

[0077] When the distance between the first mobile terminal and any second mobile terminal is less than the safety distance corresponding to the any second mobile terminal, the first mobile terminal sends warning prompt information to the any second mobile terminal.

[0078] In this way, the actual distance between mobile terminals can be compared with the safety distance, and warning prompt can be performed when the actual distance is less than the safety distance, thereby effectively preventing accidents.

[0079] In a possible implementation, the first mobile terminal is a vehicle-mounted terminal, and when it is determined that the first mobile terminal meets the safety warning condition, the first mobile terminal can send warning prompt information to the at least one second mobile terminal, which can include:

[0080] When it is determined that the driver of the vehicle in which the first mobile terminal is located has a target driving behavior, the first mobile terminal sends warning prompt information to the at least one second mobile terminal, and the target driving behavior includes one of lane changing, overtaking, and emergency braking.

[0081] It should be understood that the vehicle-mounted terminal can determine the target driving behavior through an accelerator pedal force sensor, a brake pedal force sensor, a steering wheel angle sensor, and the like. For example, by detecting the force applied by the driver on the accelerator pedal, it can be determined whether the driver intends to accelerate the vehicle, and when the change and amplitude of the force applied by the accelerator pedal exceed a threshold value, it can be determined that the driver's intention is to accelerate or overtake; by detecting the force applied by the driver on the brake pedal, it can be determined whether the driver intends to decelerate or brake the vehicle. When the force applied by the brake pedal exceeds a certain threshold value, it can be determined that the driver's intention is to brake urgently; the steering wheel angle sensor can measure the force and angle of the steering wheel applied by the driver, and according to the change and amplitude of the steering wheel angle, it can be determined whether the driver has the intention to change lanes.

[0082] By the above manner, when it is determined that the driver of the vehicle where the mobile terminal is located has the target driving behavior, the early warning prompt information can be sent to the handheld terminals and the vehicle-mounted terminals within the range of the ad hoc network, thereby effectively preventing accidents from occurring.

[0083] In a possible implementation, the method can further include:

[0084] The first mobile terminal receives feedback information sent by the at least one second mobile terminal for the early warning prompt information;

[0085] The first mobile terminal warns the driver according to the feedback information, in a case where it is determined that the target driving behavior will affect the motion state of the at least one second mobile terminal.

[0086] For example, in a case where the vehicle where the first mobile terminal is located is a rear vehicle and the vehicle where one of the other mobile terminals is located is a front vehicle, when it is detected that the rear vehicle driver corrects the steering wheel after turning the steering wheel and it is detected that the signal of the accelerator pedal sensor is greater than a preset threshold, it can be determined that the target driving behavior is lane changing and overtaking, and the early warning prompt information is sent to the front vehicle. If the front vehicle detects that the signal of the brake pedal force sensor is within a preset threshold range, it is determined that the target driving behavior is braking, and the feedback information is sent to the rear vehicle. At this time, according to the feedback information, it can be determined that the target driving behavior of the rear vehicle will not affect the motion state of the front vehicle, and no warning is performed. If the front vehicle detects that the signal of the accelerator pedal force sensor is greater than a preset threshold and the steering wheel angle is greater than a preset threshold, it is determined that the target driving behavior of the front vehicle is lane changing, and the feedback information is sent to the rear vehicle. At this time, according to the feedback information, it can be determined that the target driving behavior of the rear vehicle will affect the motion state of the front vehicle, and the driver is warned.

[0087] By the above manner, the accident risk that can be caused by the target driving behavior can be more accurately evaluated according to the information fed back by the other terminals, thereby helping to improve the comprehensiveness and reliability of the safety warning.

[0088] In a possible implementation, the type of the first mobile terminal is a vehicle-mounted terminal, and in a case where it is determined that the first mobile terminal meets the safety warning condition, the first mobile terminal can send the early warning prompt information to the at least one second mobile terminal, which can include:

[0089] The first mobile terminal determines that the vehicle is in an out-of-control state according to at least one of the wheel slip rate, the tire pressure, and the engine oil pressure of the vehicle where the first mobile terminal is located;

[0090] The first mobile terminal sends the early warning prompt information to the at least one second mobile terminal.

[0091] It should be understood that by detecting the numerical changes of the wheel slip ratio, tire pressure and oil pressure, it can be determined whether the vehicle is in an out-of-control state, including vehicle side slip, tire burst and oil leakage.

[0092] Specifically, the slip ratio refers to the ratio between the rotation speed of the vehicle tire and the actual driving speed of the vehicle. When the slip ratio suddenly increases, it means that the vehicle may be in a side slip situation, i.e. the vehicle loses traction on the road and cannot maintain stable driving. In this case, the vehicle is easy to lose control, causing serious traffic accidents; the tire pressure drops sharply, which means that the vehicle may be in a tire burst situation, which will cause the vehicle to lose stability and the driver to be difficult to control the direction and driving of the vehicle, thereby posing a great threat to surrounding vehicles and pedestrians; the oil pressure drops sharply, which means that the vehicle may be in an oil leakage situation, which will cause the vehicle power system to fail, such as the brake system losing effect or the engine stalling. In this case, the driver will lose control of the vehicle, and the vehicle may not be able to stop or accelerate, posing a serious threat to surrounding vehicles and pedestrians.

[0093] In the above manner, the out-of-control state of the vehicle can be timely warned, thereby helping the driver to take appropriate measures to reduce the loss caused by occasional accidents.

[0094] In a possible implementation, the first mobile terminal is a handheld terminal, and in a case where it is determined that the first mobile terminal meets the safety warning condition, the first mobile terminal sends a warning prompt information to at least one second mobile terminal, which can include:

[0095] The first mobile terminal determines that the pedestrian corresponding to the first mobile terminal has a dangerous behavior according to the position of the first mobile terminal and the speed of the first mobile terminal moving towards the lane.

[0096] The first mobile terminal sends a warning prompt information to at least one second mobile terminal.

[0097] The first mobile terminal determines that the pedestrian corresponding to the first mobile terminal has a dangerous behavior according to the position of the first mobile terminal and the speed of the first mobile terminal moving towards the lane.

[0098] When at least one of the following conditions is met: the position of the first mobile terminal is in a non-pedestrian area, and the speed of the first mobile terminal moving towards the lane is greater than a preset safety threshold, it is determined that the pedestrian corresponding to the first mobile terminal has a dangerous behavior.

[0099] It should be understood that through the position information of the pedestrian, it can be determined whether the pedestrian is in a non-pedestrian area, which can be a vehicle passing area, a dangerous area or an area where pedestrians are prohibited from passing. If the pedestrian is detected to be in these areas, it means that the position is unsafe, so it can be determined that the pedestrian corresponding to the handheld terminal has a dangerous behavior.

[0100] It should also be understood that by combining the motion speed of the pedestrian and the road information, it can be determined whether the pedestrian is approaching the lane at a speed greater than a safety threshold. If the pedestrian quickly moves from the sidewalk to the lane, the speed exceeds the preset safety threshold, and in this case, the pedestrian does not have enough time and space to avoid the vehicle, which can cause an accident, it can be determined that the pedestrian corresponding to the handheld terminal has dangerous behavior.

[0101] In the above manner, when the handheld terminal determines that the corresponding pedestrian has dangerous behavior according to the location and the speed of the pedestrian moving to the lane, the handheld terminal can send a warning prompt message to the vehicle-mounted terminal in the ad hoc network, thereby effectively improving the safety of pedestrians and avoiding serious accidents.

[0102] FIG. 2 is a flowchart illustrating a communication method according to an example embodiment of the present disclosure. Referring to FIG. 2, the communication method can include the following steps:

[0103] In step S201, the second mobile terminal is located in an ad hoc network centered on the first mobile terminal, and the second mobile terminal sends a message to the first mobile terminal or receives a message from the first mobile terminal, wherein the first mobile terminal and the second mobile terminal are of different types.

[0104] Optionally, the first mobile terminal is a vehicle-mounted terminal and the second mobile terminal is a handheld terminal, or the second mobile terminal is a vehicle-mounted terminal and the first mobile terminal is a handheld terminal.

[0105] For example, in a traffic scenario involving pedestrians and vehicles, the first mobile terminal can be a vehicle-mounted terminal representing a vehicle, and the second mobile terminal can be a handheld terminal representing a pedestrian. The second mobile terminal is located in an ad hoc network centered on the first mobile terminal, and the second mobile terminal sends a message to the first mobile terminal or receives a message from the first mobile terminal, thereby achieving information exchange between people and vehicles.

[0106] In the above manner, information exchange between different types of mobile terminals can be performed through an ad hoc network, and cooperative communication between heterogeneous mobile terminals is achieved, thereby improving the comprehensiveness and reliability of safety warnings.

[0107] In one possible implementation, the message from the first mobile terminal includes a warning prompt message.

[0108] The warning prompt message includes a target driving behavior of the first mobile vehicle-mounted terminal vehicle, and the method can further include:

[0109] In a case where the motion state of the second mobile terminal will affect the target driving behavior, the second mobile terminal sends feedback information to the first mobile terminal, and the feedback information is used for the first mobile terminal to give a warning to the driver of the vehicle.

[0110] In this way, the cross-terminal cooperative perception and active warning mechanism enables the driver of the vehicle to timely learn the influence of the change of the surrounding environment on the self behavior, and can improve the comprehensiveness and reliability of the safety warning.

[0111] FIG. 3 is a schematic diagram of a self-organizing network according to an example embodiment of the present disclosure. Referring to FIG. 3, the vehicle terminal corresponding to the fourth vehicle 4 can receive the warning information sent by the vehicle terminal corresponding to the first vehicle 1 within the self-organizing network centered on the vehicle terminal corresponding to the first vehicle 1. The vehicle terminal corresponding to the fourth vehicle 4 can also receive the warning information sent by the handheld terminal corresponding to the pedestrian 2 within the self-organizing network centered on the handheld terminal corresponding to the pedestrian 2. The vehicle terminal corresponding to the fourth vehicle 4 is outside the self-organizing network centered on the vehicle terminal corresponding to the third vehicle 3, and thus cannot receive the warning information sent by the vehicle terminal corresponding to the third vehicle 3.

[0112] In this way, unnecessary interference and false positives can be reduced, and the driver or pedestrian can be prevented from being frequently disturbed by irrelevant warning information, thereby ensuring that the warning information is more accurate and reliable.

[0113] The example embodiments of the present disclosure also provide a first communication device. Referring to FIG. 4, the first communication device 400 can include:

[0136] determine whether the first mobile terminal is at risk of collision according to the motion state of the first mobile terminal and the motion state of at least one of the second mobile terminals;

[0137] in a case where it is determined that the first mobile terminal is at risk of collision with any of the second mobile terminals, the first mobile terminal sends pre-warning prompt information to the second mobile terminal at risk of collision.

[0138] Optionally, the pre-warning module is configured to:

[0139] in a case where the distance between the first mobile terminal and any of the second mobile terminals is less than the safety distance corresponding to the second mobile terminal, the first mobile terminal sends pre-warning prompt information to the second mobile terminal.

[0140] Optionally, the first mobile terminal is a vehicle-mounted terminal, and the pre-warning module is configured to:
