The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0063] In view of the shortcomings or defects of the related technology, the present application provides a method for seeking assistance for unexpected parking, which can be applied to Figure 1 In the application environment shown, this method can combine the vehicle computer and warning terminals inside and outside the vehicle to help people in the vehicle, such as the driver and passengers, request corresponding assistance services from the outside world, so that people in the vehicle can get corresponding assistance more simply, safely and conveniently.

[0064] The method is described below through some implementation methods.

[0065] In some embodiments, the present application provides a method for requesting assistance for an unexpected parking, which can be applied to a vehicle terminal in a vehicle, such as Figure 2 As shown, the method includes steps S110-S130, and the details of each step are as follows.

[0066] S110: After determining that the vehicle has stopped unexpectedly, executing a first assistance operation and sending information related to the unexpected parking to a warning terminal located behind the vehicle.

[0067] In this embodiment, the vehicle terminal can confirm that the current parking of the vehicle is an unexpected parking in an active or passive manner.

[0068] For example, in one embodiment, the driver (for example only, or other persons in the vehicle) can click the unexpected parking button in the application running on the vehicle terminal to trigger the unexpected parking instruction. The vehicle terminal can confirm that the current parking of the vehicle is an unexpected parking after receiving the unexpected parking instruction. There are many reasons for the unexpected parking. For example, the reasons for the accidental parking of the above-mentioned vehicle may include at least a car accident, the driver's physical illness, vehicle failure and harsh environment, etc. In order to accurately provide the driver with the assistance services he needs, corresponding unexpected parking types can be set for various reasons for unexpected parking. Accordingly, multiple buttons corresponding to different types of unexpected parking can be set in the application to facilitate the driver to click the corresponding button according to the specific situation. In this embodiment, after the vehicle stops, the vehicle terminal does not need to actively detect whether the vehicle has an unexpected parking. When the driver needs to request assistance, the virtual unexpected parking button can be operated to instruct the vehicle terminal to perform the relevant assistance operation. For example, the driver clicks the button corresponding to the car accident. In response to the driver's operation, the vehicle terminal can determine that the vehicle has an unexpected parking and the reason for the accidental parking of the vehicle is a car accident. It is feasible that a physical unexpected parking button can be used to replace the virtual parking button provided in the application.

[0069] In another embodiment, after detecting that the vehicle has stopped, the vehicle computer can actively detect whether the vehicle has encountered a traffic accident, a malfunction, or other specific conditions. If so, it can be confirmed that the vehicle has stopped unexpectedly, and based on the detected specific conditions, the cause of the accidental stopping of the vehicle can be determined.

[0070] In some embodiments, before executing the first assistance operation and sending information related to unexpected parking to the warning terminal placed behind the vehicle, the method further includes:

[0071] In response to determining that the vehicle stops unexpectedly, detecting a reason for the vehicle stopping unexpectedly; the reason for the vehicle stopping unexpectedly includes a car accident, a driver's illness, a vehicle failure and / or a bad environment;

[0072] generating an unexpected parking type for indicating the detected cause, and determining a target service to be requested for assistance according to the unexpected parking type;

[0073] Determine a corresponding assistance operation as a first assistance operation according to the type of unexpected parking and the service type of the target service;

[0074] Generate information related to the unexpected parking according to the unexpected parking type and the service type of the target service.

[0075] Furthermore, in some embodiments, there are multiple reasons for the accidental parking of the vehicle, and different reasons are accompanied by different conditions, and different conditions have different urgency levels when being handled. In order to promptly handle the high-urgency conditions, this embodiment sets different detection priorities for various reasons. Exemplarily, assuming that the reasons for the accidental parking of the above-mentioned vehicle include a car accident, a driver's physical illness, a vehicle failure, and a harsh environment, the detection priorities from high to low are car accident > driver's physical illness > vehicle failure > harsh environment. Accordingly, the following operations can be used to detect the cause of the accidental parking of the above-mentioned vehicle, namely:

[0076] Detect whether the above-mentioned vehicle is involved in a traffic accident;

[0077] If a car accident occurs, it is determined that the above causes are car accidents;

[0078] If there is no traffic accident, detect whether the driver has specific symptoms based on the currently acquired in-car environment photos, geographic location information and weather environment information;

[0079] If specific symptoms occur, it is determined that the above reasons are due to the driver's physical illness;

[0080] If no specific symptoms occur, check the above vehicle for specific faults;

[0081] If a specific fault occurs, determine that the above cause is a vehicle fault;

[0082] If no specific fault occurs, determine the current road condition based on the currently acquired geographic location information and weather environment information, and detect whether specific weather or specific road conditions occur based on the weather environment information and the current road condition;

[0083] If so, determine that the cause is a harsh environment.

[0084] The above-mentioned photos of the vehicle interior environment can be captured by the vehicle camera. The above-mentioned specific symptoms can be physical fatigue, sudden illness, recurrence of old illness, motion sickness, emotional fluctuations, altitude sickness, fever and cold, dizziness, etc. The above-mentioned specific faults can be, for example, engine damage, abnormal tire pressure, night headlight damage, vehicle oil shortage, water tank shortage resulting in excessive water temperature, etc.

[0085] In this embodiment, each reason has a corresponding unique unexpected parking type, and the content of the unexpected parking type can be a number, a character string, etc.

[0086] Different reasons for the accidental parking of the vehicle have different assistance services, so one or more corresponding assistance services can be set for each type of accidental parking according to the specific application scenario, wherein the assistance services corresponding to different types of accidental parking may overlap. For example, the assistance services corresponding to the accidental parking type indicating a car accident include medical assistance and / or traffic accident assistance; the assistance services corresponding to the accidental parking type indicating the driver's physical illness include medical assistance, surrounding paid assistance and / or designated driver service; the assistance services corresponding to the accidental parking type indicating vehicle failure include towing service and / or surrounding paid assistance.

[0087] The operation of determining the target service to be requested for assistance according to the type of unexpected parking can be achieved through the following operations, namely:

[0088] Presenting prompt information in the form of voice announcement and / or graphic display to confirm to the driver whether to request assistance service corresponding to the type of unexpected parking;

[0089] If an assistance service selection instruction for the prompt information is detected, the assistance service corresponding to the assistance service selection instruction is used as the target service;

[0090] If no response operation to the prompt message is detected within a preset time period, a target service is selected from all assistance services corresponding to the unexpected parking type according to preset service selection rules.

[0091] The above-mentioned prompt information can be presented to the occupants of the vehicle by voice broadcasting through the audio system in the vehicle controlled by the vehicle computer, or by text and graphics displaying through the vehicle screen in the vehicle controlled by the vehicle computer. The content of the prompt information is related to the currently determined type of unexpected parking, and the content of the prompt information can be preset or generated based on actual information and preset information templates. Some examples are given below to illustrate.

[0092] (1) When the cause of the unexpected parking type is a car accident, the vehicle computer prompts "Does the driver need medical assistance?" and "Does the driver need traffic accident assistance?" in sequence. When the driver responds with a voice command of "Yes" or "No" or the driver clicks the "Yes" or "No" button on the vehicle screen, the voice prompt will terminate. When a voice command or click operation is detected, the target service can be determined. For example, if the vehicle computer prompts "Does the driver need medical assistance?" and then detects the voice command of "Yes", it can be determined that the target service is medical assistance.

[0093] If the vehicle computer detects that the driver has not responded with "yes" or "no", the voice prompt will be played every 10 seconds until the number of plays reaches the upper limit, for example, 12 times. If the driver has not responded, the vehicle computer determines that the driver is injured and unconscious, and selects the target assistance according to the preset service selection rules. The rules can be set according to the specific situation. For example, when the driver has not responded for a long time, the vehicle computer directly determines that the target service is medical service.

[0094] 2) When the reason for the unexpected parking type is that the driver is ill, the vehicle terminal will give voice prompts in the order of "Does the driver need medical services?", "Does the driver need paid assistance from the surrounding area?", and "Does the driver need a designated driver service?" The driver can use the corresponding voice commands or operations to make choices according to their needs.

[0095] 3) When the cause of the unexpected parking type is a vehicle failure, the vehicle terminal will voice broadcast prompts in sequence "Do you need a towing service?" and "Do you need to buy gasoline or water for a fee?" The driver can use the corresponding voice instructions or operations to make choices according to their own needs. For example, if the driver needs a towing service, after the vehicle terminal voice broadcasts "Do you need a towing service?", just reply "Yes". For another example, the vehicle terminal voice broadcasts "Do you need to buy gasoline or water for a fee?", the driver can reply "Yes gasoline."

[0096] 4) When the cause of the unexpected parking type is a bad environment, the vehicle terminal can play a voice message "Do you need traffic rescue?"

[0097] The above-mentioned assistance operation determined according to the type of unexpected parking and the service type of the target service as the first assistance operation is performed separately by the vehicle terminal. In some embodiments, the assistance operation determined according to the type of unexpected parking and the service type of the target service includes:

[0098] Generate assistance information corresponding to the target service and broadcast the assistance information to the vehicle terminals of surrounding vehicles;

[0099] Send assistance information to the rescuer corresponding to the target service;

[0100] lowering the windows of the above vehicles;

[0101] turning on the specified lights on the above vehicles; and / or,

[0102] Control the above vehicle's audio system to play assistance information at a specific volume.

[0103] In this embodiment, when the types of unexpected parking are different or the types of target services are different, the assistance operations that need to be performed by the vehicle terminal are different.

[0104] For example, in the event of a car accident, the car computer will broadcast a voice message "Do you need medical assistance and traffic accident assistance?" If the driver replies "Yes," the car computer will send the driver's information (including the driver's identity information, contact information, etc.) and the vehicle's current geographic location information to the local hospital and traffic law enforcement department. In addition, the car computer can also send the current geographic location information and traffic accident information to the cloud platform for recording. If the car computer has not received a reply, and the car computer determines that the driver is injured and unconscious and needs assistance, the car computer will automatically lower the window, adjust the volume of the car audio to the maximum, turn on the double flash lights, and play voice assistance information such as "License plate number xxxx has had a car accident, the vehicle has turned on the double flash lights and stopped at the roadside, the driver has fainted, please ask the surrounding caring people to rescue the driver and send him to the hospital for treatment." At the same time, the car computer will broadcast the assistance information to the car computers of surrounding vehicles to request assistance.

[0105] In some embodiments, generating assistance information corresponding to the target service includes:

[0106] 1. If the unexpected parking type indicates that the driver is ill, and the target service is medical assistance or paid assistance in the surrounding area, the driver's demand information for medical supplies is collected, and assistance information is generated based on the demand information.

[0107] If the driver suddenly becomes ill and cannot continue driving, the driver can instruct the car terminal to request medical assistance and / or paid services in the surrounding area. For example, assuming that the driver has altitude sickness, the driver can instruct the car terminal to request "paid assistance in the surrounding area", then the car terminal can prompt "Does the driver need motion sickness medicine, oxygen cylinder or other", and the driver can reply "motion sickness medicine", "oxygen cylinder" or "other". The car terminal will determine whether to continue to prompt the driver to feedback more specific item information based on the driver's reply content to obtain the driver's demand information for medical supplies. For example, the driver replies "oxygen cylinder". At this time, the car terminal can determine that the driver's demand information for medical supplies is oxygen cylinder. If the driver replies "other", the car terminal needs to further prompt, such as a voice prompt "Please provide specific information of the demand", and the driver can enter specific item information, such as asthma spray, through voice commands or on the car terminal. Feasibly, when the driver submits "asthma spray", the car terminal will save the record locally so that the asthma spray will be automatically attached when the voice prompt is given next time.

[0108] After determining the driver's demand information for medical supplies, assistance information is generated based on the demand information and the preset information template. For example, the vehicle computer automatically adjusts the in-car audio to the maximum volume, turns on the double flash, lowers the car window, and plays assistance information by voice, such as "The vehicle with license plate number xxxx is asking for help with 'oxygen cylinders' for a fee. The vehicle has turned on the double flash and stopped at the roadside. We hope that kind people with 'oxygen cylinders' can provide assistance." In the above assistance information, the oxygen cylinder in single quotes is the driver's demand information for medical supplies, and the other content is the information in the preset information template.

[0109] 2. If the unexpected parking type indicates a vehicle failure and the target service is paid assistance in the surrounding area, the driver's demand information for driving supplies is collected, and assistance information is generated based on the demand information.

[0110] When the vehicle breaks down, such as when the water tank is empty, the car computer will announce "Do you need to buy clean water for a fee?" If the driver replies "Yes," the car computer will automatically adjust the volume of the in-car audio to the maximum, turn on the hazard lights, lower the windows, and play assistance information, such as "Vehicle with license plate number xxxx needs help with 'clean water' for a fee. The vehicle has turned on the hazard lights and stopped at the roadside. We hope that caring people with 'clean water' can provide assistance."

[0111] Furthermore, in addition to executing the rescue operation itself, the vehicle terminal will also send the unexpected parking related information to the warning terminal placed behind the vehicle to instruct the warning terminal to execute the corresponding rescue operation according to the unexpected parking related information. The rescue operation executed by the warning terminal will be described in detail below.

[0112] S120: Receive a rescue response message, where the rescue response message is generated by a vehicle computer in another vehicle to respond to the rescue message broadcast by the warning terminal based on information related to the unexpected parking.

[0113] The rescue response information received by the vehicle terminal is sent by the vehicle terminal in other vehicles to the warning terminal and then conveyed to the vehicle terminal by the warning terminal; or it is sent by the vehicle terminal in other vehicles to the vehicle terminal when it determines that it is closer to the vehicle terminal after generating the rescue response information.

[0114] S130: Execute a second assistance operation obtained by adjusting the operation content of the first assistance operation according to the assistance response information.

[0115] In this embodiment, the vehicle terminal can use the additional information generated by the distance between the vehicle and the warning terminal to adjust the specific assistance operation performed. Specifically, when the vehicle stops unexpectedly and needs to seek assistance from the outside world, the vehicle terminal can send the warning terminal related information about the unexpected parking to instruct the warning terminal to perform the corresponding assistance operation while executing the first assistance operation. Since there is a certain distance between the vehicle and the warning terminal, the assistance range can be expanded in space. In addition, since the warning terminal is set behind the vehicle, the warning terminal can detect other vehicles behind the vehicle faster than the vehicle terminal in time, and can remind the vehicle terminal when it is judged that there is a dangerous situation, so that the vehicle terminal can remind the people in the car to avoid danger, and can also convey the assistance response information sent by the vehicle terminal of other vehicles to the vehicle terminal when receiving it, so that the vehicle terminal can adjust the first assistance operation accordingly.

[0116] Among them, the operation content of the first rescue operation adjusted according to the rescue response information includes one or more of the following: light warning form, information broadcast form, and broadcast content.

[0117] For example, after receiving information related to accidental parking, the warning terminal broadcasts a distress message, such as "The vehicle with license plate number xxxx is asking for help with an 'oxygen cylinder' for a fee. The vehicle has turned on the hazard lights and stopped at the roadside. We hope that kind-hearted people with 'oxygen cylinders' can provide assistance." After receiving the distress message, the car computer terminals of other vehicles can return a distress response message to the warning terminal under the operation of the drivers of other vehicles (or other people in the car), for example, "I am the driver of the vehicle with license plate number xxxx. There is an oxygen cylinder in the car. I'm going over to rescue it now. Do you need any help?" After receiving the distress response message, the warning terminal conveys it to the car computer terminal. The adjustment made by the car computer terminal may be to send feedback information, such as "Thank you for your help. Please tell more people about the current information here."

[0118] In some embodiments, if the unexpected parking type indicates a severe environment, the method further includes:

[0119] Determine the current road condition based on the currently acquired geographic location information and weather environment information, and present warning information corresponding to the current road condition together with the warning terminal;

[0120] When the current road condition is confirmed to be a specific road condition, the description and analysis information of the current road condition is collected from the driver;

[0121] Send traffic information containing descriptive analysis information and geographic location information.

[0122] In this embodiment, the vehicle terminal combines geographic location information and weather environment information to determine the road conditions of the current road section. For example, if the vehicle terminal detects that the current weather is foggy and snowy, and the current road is a steep mountain road, it will give voice prompts such as "keep slowing down ahead" and "the road ahead is narrow, please pay attention, driver". The vehicle terminal can also send the voice broadcast information to the warning terminal for voice playback to expand the warning range. For another example, if there are specific road conditions such as road collapse and hillside mudslides, the vehicle terminal can prompt the driver to enter the description and analysis information of the current road conditions on the vehicle screen, such as the driver's text description of the current road conditions, the pictures taken, and the analysis of the causes of the current road conditions. Taking road collapse as an example, the driver can fill in the specific questions, and the vehicle terminal will send the question content, current geographic location information, etc. to the transportation department and other relevant departments. At the same time, the vehicle terminal can send the information that the road ahead is impassable to the warning terminal, so as to remind the nearby vehicles to change lanes through the warning terminal to avoid long-term traffic congestion.

[0123] In some embodiments, the road condition information may also include driver information, such as the driver's name, contact information, etc., so that relevant departments can contact the driver and learn the road condition details more quickly. In other embodiments, if the driver needs help, the road condition information may also include the driver information and related help information.

[0124] The vehicle computer can also send the description and analysis information to the cloud platform, so that the cloud platform can update the driving routes for other vehicles based on the description and analysis information, avoiding traffic congestion caused by more vehicles driving into the current section without knowing it.

[0125] In some embodiments, the above method further comprises:

[0126] receiving collision warning information sent by the warning terminal when a collision event is detected;

[0127] In response to the collision warning information, the safety avoidance warning information is presented in the form of voice broadcast and / or graphic display.

[0128] In this embodiment, a collision sensor is installed in the warning terminal. When the collision sensor of the warning terminal detects a collision signal, the warning terminal will detect a collision event, and then send corresponding collision warning information to the vehicle terminal to alert the vehicle terminal, so that the vehicle terminal can promptly remind the people in the car to take corresponding actions.

[0129] In some embodiments, the collision warning information may include collision level information for indicating the severity of the collision, and accordingly, the vehicle terminal may adjust the warning method according to the collision level information. For example, assuming that a higher collision level indicates a higher severity of the collision, when the collision level information indicates a higher collision level, the volume of the voice broadcast by the vehicle terminal is louder and the speech speed is faster; conversely, when the collision level information indicates a lower collision level, the volume of the voice broadcast by the vehicle terminal is relatively lower and the speech speed is relatively slower.

[0130] Furthermore, the collision warning information may also include vehicle speed information so that the occupants of the vehicle can better understand the situation of the vehicle behind and take better actions.

[0131] Furthermore, the collision warning information can also include the license plate information of other vehicles. Specifically, the warning terminal carries the license plate information of the vehicle involved in the collision event in the collision warning information and sends it to the vehicle terminal. After receiving the information, the vehicle terminal will prompt the people in the car or the people around the vehicle to avoid the collision safely through voice broadcast or graphic display, so as to further ensure the personal safety of the relevant personnel. The vehicle terminal can also upload the license plate of the nearby vehicle to the cloud platform for storage, so as to avoid being unable to find the vehicle after the vehicle is hit and run.

[0132] In some embodiments, the vehicle computer can respond to instructions for viewing information on areas where accidental parking is frequent, request the cloud platform to obtain information on areas where accidental parking is frequent, and then provide voice prompts based on the vehicle's current location information, such as "There is an area ahead where traffic accidents are frequent, please slow down", "The road ahead is congested, do you need to change lanes, etc.", so that people in the car can drive safely and smoothly.

[0133] In some embodiments, the vehicle terminal can also receive assistance information broadcast by the vehicle terminals of other vehicles, and the vehicle terminal will give voice broadcast prompts of the received assistance information so that people in the vehicle can help others.

[0134] In some embodiments, the vehicle terminal can receive warning information broadcast by the warning terminal of the vehicle terminal bound to other vehicles. The vehicle terminal will actively send the license plate information of the vehicle to the warning terminal, and voice broadcast the warning information broadcast by the warning terminal, such as "150 meters ahead, there is a vehicle accidentally parked on the right side of the road, please slow down", so that the driver of the vehicle can perceive in advance that there is a vehicle parked ahead, and then slow down and avoid it reasonably to ensure the safety of the people related to the vehicle and other vehicles.

[0135] In other embodiments, the present application provides a method for seeking assistance for an unexpected parking, which can be applied to a warning terminal placed behind a vehicle, such as Figure 3As shown, the method includes steps S210-S230, and the details of each step are as follows.

[0136] S210: Receive information related to unexpected parking sent by a vehicle terminal installed in the above vehicle.

[0137] S220: Execute corresponding assistance operations according to the information related to the unexpected parking.

[0138] S230: Transmitting a rescue response message to the vehicle terminal; the rescue response message is information generated by the vehicle terminal in other vehicles to respond to the rescue message broadcast by the warning terminal based on the information related to the unexpected parking.

[0139] The assistance operation includes broadcasting assistance information based on information related to the unexpected parking.

[0140] In this embodiment, the warning terminal can be modified based on a traditional warning sign placed behind a vehicle for warning. The warning terminal needs to be set to a certain distance behind the vehicle when in use, and the length of the distance is determined according to relevant traffic regulations. For example, if the current vehicle is on a city road and it is daytime, the warning terminal needs to be placed 50 meters behind the vehicle. If the current vehicle is on a city road and it is night, the warning terminal needs to be placed 100 meters behind the vehicle. If the current vehicle is on a highway or it is foggy and rainy, the warning terminal needs to be placed about 150-200 meters behind the vehicle.

[0141] The information related to the unexpected parking includes one or more of weather and environmental information, road orientation information, geographic location information, time information, and the type of unexpected parking. The above-mentioned road orientation information is used to indicate the orientation of the vehicle on the current road, such as the vehicle is on the left side, right side, or middle of the road. The information related to the unexpected parking may also include the driver's demand information for medical supplies and / or the driver's demand information for driving supplies.

[0142] The help request information is generated based on the information related to the accidental parking. For example, if the accidental parking type is a car accident, the help request information may be "'150 meters ahead', 'right side of the road', a vehicle has accidentally parked, the driver of the vehicle has fallen into a coma, please slow down and provide rescue."

[0143] If the type of unexpected parking is due to the driver's physical illness, and the driver's demand for medical supplies is oxygen cylinders, the request for help can be "'150 meters ahead', 'right side of the road', a vehicle has unexpectedly parked, the driver of the vehicle wants to buy 'oxygen cylinders' for a fee, please slow down."

[0144] If the type of unexpected parking is vehicle failure, and the driver's demand for driving supplies is No. 95 gasoline, then the assistance message can be "'150 meters ahead', 'right side of the road', a vehicle has unexpectedly parked, the driver of the vehicle wants to buy 'No. 95 gasoline' for a fee, please slow down."

[0145] If the type of unexpected parking is a severe environment, the assistance message may be “'150 meters ahead', 'road collapse', please slow down or change lanes”.

[0146] In the above-mentioned help request information, the information in single quotes is obtained by the warning terminal based on the currently received information related to the accidental parking, while the other contents are preset information templates. Among them, the above-mentioned "150 meters ahead" refers to the actual distance between the warning terminal and the target vehicle (referring to the vehicle close to the warning terminal), which is calculated by the warning terminal in real time based on the communication signal information (such as Bluetooth signal strength information) of the target vehicle obtained.

[0147] If the vehicle computer in other vehicles receives the assistance information broadcast by the warning terminal, it can send the assistance response information to the warning terminal, and the warning terminal will convey the assistance response information to the vehicle computer.

[0148] In some embodiments, the above method further comprises:

[0149] Detect the speed of the target vehicle, which is the vehicle currently approaching the warning terminal;

[0150] Calculate the estimated braking distance between the target vehicle and the above vehicle based on the speed of the target vehicle, and calculate the actual distance between the target vehicle and the above vehicle based on the communication signal strength information;

[0151] When the estimated braking distance is greater than or equal to the actual distance, a preset warning operation is executed; the preset warning operation includes one or more of the following:

[0152] Determine a target traffic indicator light from a plurality of traffic indicator lights corresponding to different directions installed on the warning terminal according to the road direction information and the geographical location information, and turn on the target traffic indicator light;

[0153] A target voice warning mode and / or a target light warning mode is determined according to the information related to the unexpected parking, and a warning operation corresponding to the target voice warning mode and / or the target light warning mode is executed.

[0154] In this embodiment, the above-mentioned estimated braking distance indicates the distance between the position of the target vehicle when it stops and the position when it starts braking if the target vehicle brakes at the current speed. By comparing the actual distance between the target vehicle and the host vehicle with the estimated braking distance, it can be determined whether the host vehicle is safe. For example, if the estimated braking distance is greater than or equal to the actual distance (that is, the actual distance is less than the estimated braking distance), it indicates that the target vehicle is traveling too fast and may bring danger to the host vehicle. At this time, it is necessary to promptly remind the relevant personnel in the host vehicle to evacuate and avoid danger.

[0155] The warning terminal obtains the speed of the target vehicle in real time, and then estimates the estimated braking distance between the target vehicle and the vehicle. The calculation formula is FS = Mv^2 / 2, where F is the resistance during braking, including air resistance and braking friction. The complete formula for calculating the estimated braking distance is: (Mgf+(1 / 2)ρ·s·c·v^2)S = Mv^2 / 2

[0156] In the above complete formula, M is the mass of the car, g is the acceleration due to gravity, f is the coefficient of ground friction, ρ is the air density, s is the frontal area of ​​the car, c is the drag coefficient, S is the braking distance, and v is the current speed. The formula means that the braking distance is calculated based on the current kinetic energy, friction, and air resistance of the vehicle. The final formula is S = mv^2 / (ρ·s·c·v^2+2mgf)

[0157] Considering that the driver of the target vehicle needs time to react after receiving the relevant warning information from the warning terminal, S = (mv^2 / (ρ·s·c·v^2+2mgf))+vs. Among them, s is the reaction time. That is, the estimated braking distance S = (mv^2 / (ρ·s·c·v^2+2mgf))+vs+50. 50 in the formula is the minimum distance between the warning terminal and the vehicle.

[0158] The warning terminal calculates the actual distance between the target vehicle and the vehicle (i.e. the vehicle that stopped unexpectedly) by the following formula: S = 10^((abs(Rssi)-A) / (10*n))+50

[0159] In the above formula, S is the distance between the host vehicle and the target vehicle, abs(Rssi) is the absolute value of the communication signal strength, A is the signal strength when the target vehicle is 1 meter away from the warning terminal, n is the environmental attenuation factor, and 50 is the minimum distance between the warning terminal and the host vehicle. The communication signal strength refers to the signal strength when the warning terminal and the target vehicle communicate. If the two communicate via Bluetooth, the communication signal strength is specifically the Bluetooth signal strength, and if other communication technologies are used for communication, the communication signal strength is specifically the signal strength of other communication technologies.

[0160] Furthermore, the warning terminal may be installed with a communication indicator light for indicating the left side and a traffic indicator light for indicating the right side. When the warning terminal determines the target traffic indicator light from a plurality of traffic indicator lights corresponding to different directions installed on the warning terminal according to the road direction information and the geographic location information, if it is determined that the vehicle is located on the left side of the road, the traffic indicator light for indicating the right side is turned on; if it is determined that the vehicle is located on the right side of the road, the traffic indicator light for indicating the left side is turned on; if the vehicle is located in the middle of the road, the communication indicator light for indicating the left side and the traffic indicator light for indicating the right side are turned on.

[0161] Furthermore, in some embodiments, the warning terminal may generate a target voice warning mode and / or a target light warning mode in real time according to information related to unexpected parking.

[0162] In other embodiments, the warning terminal may determine a target voice warning mode and / or a target light warning mode from a plurality of pre-set voice warning modes and a plurality of light warning modes according to information related to unexpected parking.

[0163] In some examples, the alert terminal may be configured to: Figure 4 The process shown is used to select whether to use light warning mode and / or voice warning mode.

[0164] When the warning terminal determines the target voice warning mode and the target light warning mode from the multiple voice warning modes and the multiple light warning modes according to the information related to the unexpected parking, the warning terminal can determine the target voice warning mode and the target light warning mode according to the information related to the unexpected parking according to the following examples: Figure 5 The process shown in the figure is used to execute the voice warning method, and according to the Figure 6 The process shown is used to execute the light warning method. For example, it can be to determine the level of population density corresponding to the current position of the vehicle. For example, if it is currently located in the suburbs, the level of population density is determined to be high. If it is currently located in a highway section, the level of population density is determined to be low. If the level of population density is high, the current time period is daytime and the weather is good, a voice warning method of 60 decibels is selected to voice broadcast the relevant warning information. If the time period becomes nighttime, a light warning method with lights always on is selected. In addition, when the speed of the target vehicle is too high, resulting in the actual distance being less than the estimated braking distance, the warning terminal selects a high-frequency display and high-frequency flashing light warning method, where the flashing frequency is 5Hz, and also selects a voice warning method of 120 decibels for voice broadcast.

[0165] If the population density level is low and the current time period is daytime, a voice warning method with a voice broadcast of 100 points is selected; if the time period is nighttime, a light warning method with a general frequency of 1Hz flashing lights is used; when the speed of the target vehicle is too high, resulting in the actual distance being less than the estimated braking distance, the warning terminal chooses to use a high-frequency display and high-frequency flashing light warning method with a flashing frequency of 10Hz, and at the same time, a voice warning method with a voice broadcast of 150 decibels is selected.

[0166] If the current weather is bad, such as heavy rain, heavy snow, or heavy fog, and the current time period is daytime, the voice warning mode of 120 decibels is selected, and the light warning mode of fog lamp flashing is also selected, wherein the flashing frequency is 10Hz. If the time period becomes nighttime, the light warning mode of conventional light flashing is selected.

[0167] In some embodiments, the above method further comprises:

[0168] A collision event is detected by a collision sensor, and in response to the collision event being detected, collision warning information is sent to the vehicle computer end of the vehicle, so that the vehicle computer end of the vehicle performs a corresponding warning operation.

[0169] In this embodiment, a collision sensor is installed in the warning terminal. When the collision sensor of the warning terminal detects a collision signal, the warning terminal will detect a collision event, and then send corresponding collision warning information to the vehicle terminal to alert the vehicle terminal, so that the vehicle terminal can promptly remind the people in the car to take corresponding actions.

[0170] In some embodiments, the collision warning information may include collision level information for indicating the severity of the collision, and accordingly, the vehicle terminal may adjust the warning method according to the collision level information. For example, assuming that a higher collision level indicates a higher severity of the collision, when the collision level information indicates a higher collision level, the volume of the voice broadcast by the vehicle terminal is louder and the speech speed is faster; conversely, when the collision level information indicates a lower collision level, the volume of the voice broadcast by the vehicle terminal is relatively lower and the speech speed is relatively slower.

[0171] Furthermore, the collision warning information may also include vehicle speed information so that the occupants of the vehicle can better understand the situation of the vehicle behind and take better actions.

[0172] Furthermore, the collision warning information can also include the license plate information of other vehicles. Specifically, the warning terminal carries the license plate information of the vehicle involved in the collision event in the collision warning information and sends it to the vehicle terminal. After receiving the information, the vehicle terminal will prompt the people in the car or the people around the vehicle to avoid it safely through voice broadcast or graphic display, further ensuring the personal safety of the relevant personnel. The vehicle terminal can also upload the license plate of the nearby vehicle to the cloud platform for storage, so as to avoid being unable to find the vehicle after the vehicle is approached and flees.
