The application scenarios of the embodiments of the present disclosure may be in a computer system consisting of a vehicle-mounted device and a cloud platform, and may operate with numerous other general-purpose or special-purpose computing system environments or configurations. Exemplarily, a vehicle-mounted device may be a thin client, a thick client, a microprocessor-based system, a minicomputer system, etc., mounted on a vehicle; and a cloud platform may be a distributed cloud computing environment including a minicomputer system or a mainframe computer system, etc.
The vehicle-mounted device, cloud platform, or the like may be described in the general context of computer system executable instructions (such as program modules) executed by a computer system. Generally, program modules may include routines, programs, target programs, components, logic, data structures, etc., and perform particular tasks or implement particular abstract data types. In a cloud platform, tasks are performed by remote processing devices linked through a communication network.

In some embodiments of the present disclosure, a method for driving warning is provided. The embodiments of the present disclosure may be applied to the fields of driving warning, vehicle operation management, driver management, or the like.
The method for driving warning in the embodiment of the disclosure may be applied to a cloud platform which is communicatively connected to the vehicle-mounted device.
In 101, real-time location information of a vehicle is acquired.
In the embodiment of the present disclosure, the real-time location information of the vehicle is used to represent the current geographic location of the vehicle, and the real-time location information of the vehicle may take the form of longitude and latitude data or other types of geographic location data. In practical applications, the vehicle-mounted device may report the real-time location information to the cloud platform after acquiring the real-time location information reported by the locating device.
In one example, the vehicle-mounted device may be an Advanced Driving Assistant System (ADAS) provided in the vehicle, which may obtain real-time location information of the vehicle from a locating device of the vehicle. The ADAS may send the vehicle travel data including the real-time location information of the vehicle to the cloud platform, such that the cloud platform may receive the real-time location information of the vehicle.
It should be noted that the contents of the above description are merely illustrative of an implementation of acquiring real-time location information of a vehicle by a cloud platform, and the embodiments of the present disclosure are not limited thereto.
In 102, future location information is predicted based on the real-time location information of the vehicle.
Here, the future location information indicates a location at which the vehicle may travel at a time point in the future. The distance between the location in the future location information and the real-time location of the vehicle is related to the current travel speed of the vehicle. In practical applications, the cloud platform may acquire the real-time location information of the vehicle, and may further acquire the current travel speed of the vehicle sent by the vehicle-mounted device. For example, the ADAS on the vehicle may determine the travel speed of the vehicle based on the change of the vehicle location per unit time, and then send the vehicle travel data including the current travel speed of the vehicle to the cloud platform. The cloud platform may predict a location that the vehicle may reach within a set time, i.e., future location information, based on the real-time location of the vehicle and the current travel speed of the vehicle. The setting time may be set according to an actual application demand. For example, the range of the setting time may be 10 seconds to 60 seconds.
In 103, first dangerous driving history data corresponding to the future location information is determined according to a first mapping relationship between a geographical location and the dangerous driving history data stored in the database.
In the embodiment of the present disclosure, the dangerous driving history data may include dangerous driving data when at least one driver passes a corresponding geographic location. Exemplarily, the dangerous driving history data may represent the dangerous driving data when a driver passes a corresponding geographical location. The dangerous driving history data may further represent the dangerous driving data when different drivers pass through the corresponding geographical location. Herein, for the same geographical location, each driver may pass through the same geographical location once or more times. Thus, the dangerous driving data when each driver passes through the geographical location may be the dangerous driving data when each driver passes through the geographical location once or more times.
The dangerous driving data indicates a dangerous driving condition that has occurred at a future location of the vehicle. Exemplarily, the dangerous driving data of the vehicle includes at least one of: a lane departure warning, a forward collision warning, an overspeed warning, a pedestrian in front of the vehicle, a backward collision warning, an obstacle in front of the vehicle, fatigue driving data of the driver, distracted driving data of the driver, or dangerous action data of the driver. Exemplarily, the fatigue driving data of the driver may be yawning or other fatigue travel behavior, the distracted driving data of the driver may be a distracted travel behavior such as smoking or drinking water, and the dangerous operation data of the driver may be a behavior such as making a phone call or making up.
It may be seen that the first dangerous driving history data indicates a dangerous driving condition that has occurred at a future location of the vehicle, such that the dangerous driving condition which would easily occur at the road ahead may be reflected accurately and reliably.
In practical applications, when generating the dangerous driving history data, the vehicle-mounted device provided in the vehicle may send the dangerous driving history data and the geographical location corresponding to the dangerous driving history data to the cloud platform. For example, the vehicle-mounted device may include at least one of a DMS or an ADAS, and the DMS may include a vehicle-mounted camera with the image acquisition direction of the vehicle-mounted camera facing the cabin. The DMS may analyze the driver image captured by the vehicle-mounted camera, and when determining based on the analysis result that the dangerous driving condition occurs, may generate the dangerous driving history data and determine the geographical location corresponding to the dangerous driving history data generated by the DMS. The DMS may send the dangerous driving history data and the geographic location corresponding to the dangerous driving history data to the cloud platform. Exemplarily, the dangerous driving history data generated by the DMS may include at least one of: fatigue driving data of the driver, distracted driving data of the driver, and dangerous action data of the driver. The ADAS may include a camera mounted on the vehicle and the image acquisition direction is toward the outside of the vehicle. The ADAS may perform an analysis according to the outside environment image acquired by the camera. When it is determined that a dangerous driving condition occurs according to an analysis result, the ADAS may generate dangerous driving history data, and determine a geographical location corresponding to the dangerous driving history data generated by the ADAS. The ADAS may send the dangerous driving history data and the geographical location corresponding to the dangerous driving history data to the cloud platform. Exemplarily, the dangerous driving history data generated by the ADAS may include at least one of: lane departure, forward collision, overspeed, or a pedestrian in front of the vehicle.
In some optional embodiments of the present disclosure, before determining the dangerous driving history data corresponding to the future location information, the method further includes: receiving the dangerous driving history data sent by the vehicle-mounted device and the geographical location corresponding to the dangerous driving history data, and establishing a first mapping relationship between the received geographical location and the dangerous driving history data in a database.
It may be understood that the first mapping relationship between the received geographical location and the dangerous driving history data is established in the database, such that the dangerous driving history data at the road ahead may be directly determined according to the first mapping relationship after the future location information of the vehicle is acquired, and then a warning may be issued in time.
In 104, first driving warning information is generated based on the determined first dangerous driving history data.
In the embodiment, the first driving warning information may be used to indicate a dangerous driving condition which has occurred at a future location of the vehicle. For example, the first dangerous driving history data indicates that a lane departure, a forward collision, an overspeed, or a pedestrian in front of the vehicle has occurred at a future location of the vehicle. Exemplarily, the first driving warning information may be represented in the form of prompt information for indicating that a lane departure, a forward collision, an overspeed, or a pedestrian in front of the vehicle has occurred at a future location of the vehicle.
In 105, the first driving warning information is sent to the vehicle.
In practical applications, after the cloud platform sends the first driving warning information to the vehicle, the vehicle may display the first driving warning information through the vehicle-mounted display screen, or may broadcast the first driving warning information through voice.
In practical applications, steps 101 to 105 may be implemented based on a processor or the like of a cloud platform, which may be at least one of: an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a Central Processing Unit (CPU), a controller, a microcontroller, or a microprocessor.
It may be seen that in the embodiment of the disclosure, not only the real-time location information of the vehicle is acquired, but also the future location of the vehicle is predicted, and the first driving warning information is generated according to the dangerous driving history data corresponding to the future location of the vehicle. The dangerous driving history data indicates a dangerous driving condition which has occurred at the future location of the vehicle, such that it may reflect accurately and reliably the dangerous driving condition which would easily occur at the road ahead. Further, after the vehicle receives the first driving warning information, the driver of the vehicle may learn accurately and reliably that dangerous driving condition would easily occur at the road ahead, such that the driver may take countermeasures in advance, thereby improving the safety of vehicle driving.
In some optional embodiments of the present disclosure, after predicting the future location information based on the real-time location information, the method may further include: acquiring at least one of weather condition information or traffic condition information of a geographic region corresponding to the future location information; and sending at least one of the weather condition information or traffic condition information of the geographical area corresponding to the future location information to the vehicle.
In the embodiment of the disclosure, the weather condition information includes, but is not limited to, rain, snow, fog, sunny day, night, cloudy day, or the like, and the traffic condition information includes, but is not limited to, uphill, downhill, turning, a smooth road, an uneven road, a clear road, a traffic jam, a traffic accident, or the like.
It is to be understood that at least one of the weather condition information or the traffic condition information are important factors influencing the safety of vehicle driving. Therefore, after at least one of the weather condition information or the traffic condition information of the geographical area corresponding to the future location information are sent to the vehicle, it facilitates the driver of the vehicle to comprehensively consider at least one of the weather condition information or the traffic condition information and the first driving warning information, thereby facilitating the driver to take countermeasures in advance, thereby improving the safety of vehicle driving.
For example, when the weather condition information received by the vehicle indicates that it is foggy at the geographical area corresponding to the future location information, and the first driving warning information indicates that a situation such as a vehicle collision has occurred at the road ahead, then the driver may reduce the vehicle speed, so as to improve the safety of vehicle driving. For another example, when the traffic condition information received by the vehicle indicates that the geographical area corresponding to the future location information is a road turning area, and the first driving warning information indicates that a pedestrian has traversed the road ahead, then the driver may reduce the vehicle speed to improve the safety of vehicle driving.
Referring to
In some optional embodiments of the present disclosure, after predicting the future location information based on the real-time location information, the method may further include acquiring at least one of weather condition information or traffic condition information of a geographic region corresponding to the future location information; generating second driving warning information in response to at least one of the weather condition information or the traffic condition information meeting a predetermined warning condition; and sending the second driving warning information to the vehicle.
The warning condition may be set according to an actual application scenario. For example, the warning condition may be that at least one of the weather condition information or the traffic condition information would adversely affect the safety of vehicle driving. Exemplarily, the second driving warning information may be represented in the form of prompt information for prompting at least one of the weather condition information or traffic condition information satisfying the warning condition. In the embodiments of the present disclosure, the implementation of acquiring at least one of the weather condition information or the traffic condition information of the geographical area corresponding to the future location information is described in the foregoing contents, and details are not described herein.
In practical applications, after the cloud platform sends the second driving warning information to the vehicle, the vehicle may display the second driving warning information through the vehicle-mounted display screen, or may broadcast the second driving warning information through voice.
It should be noted that when at least one of the weather condition information or the traffic condition information satisfy the predetermined warning condition, at least one of the weather condition information or the traffic condition information may be ignored.
It may be understood that at least one of the weather condition information or the traffic condition information are important factors influencing the safety of vehicle driving. Therefore, when at least one of the weather condition information or the traffic condition information satisfy the predetermined warning condition, it indicates that at least one of the weather condition information or the traffic condition information may adversely affect the safety of vehicle driving. In this case, after at least one of the weather condition information or the traffic condition information of the geographical area corresponding to the future location information are sent to the vehicle, it is convenient for the driver of the vehicle to comprehensively consider the first driving warning information and the second driving warning information, thereby facilitating the driver to take countermeasures in advance, and improving the safety of vehicle driving.
In the first example, when the second driving warning information received by the vehicle indicates that vehicle collision had occurred at the road ahead, and the first driving warning information indicates that the vehicle collision had occurred at the road ahead, then the driver may reduce the vehicle speed to improve the safety of vehicle driving. In the second example, when the second driving warning information received by the vehicle indicates that it is raining at the road ahead, and the first driving warning information indicates that vehicle overspeed had occurred at the road ahead, then the driver may reduce the vehicle speed to improve the safety of vehicle driving.
In some optional embodiments of the present disclosure, the method for driving warning in the embodiments of the present disclosure may further include: acquiring a facial feature to be analyzed; determining a facial feature of the driver matching the facial feature to be analyzed in a database in which a second mapping relationship between the facial feature of the driver and the dangerous driving history data is stored; acquiring second dangerous driving history data corresponding to the determined facial feature of the driver in the database according to the second mapping relationship; generating third driving warning information based on the first dangerous driving history data and the second dangerous driving history data; and sending the third driving warning information to the vehicle.
In the embodiment of the present disclosure, the facial feature to be analyzed may be a feature extracted from a face image of the driver. In one example, after acquiring the face image of the driver, the vehicle-mounted device may extract the facial feature of the driver from the face image of the driver using a face recognition algorithm, use the facial feature of the driver as the facial feature to be analyzed, and send the facial feature to be analyzed to the cloud platform. In another example, the vehicle-mounted device may send the face image of the driver to the cloud platform after acquiring the face image of the driver, and the cloud platform may extract the facial feature of the driver from the face image of the driver using the face recognition algorithm, and use the facial feature of the driver as the facial feature to be analyzed.
In some optional embodiments, the vehicle-mounted device provided in the vehicle may send the dangerous driving history data and the facial feature of the driver to the cloud platform before acquiring the second dangerous driving history data corresponding to the determined facial feature of the driver in the database. The cloud platform receives the dangerous driving history data and the facial feature of the driver sent by the vehicle-mounted device provided in the vehicle, and may establish a second mapping relationship between the received facial feature of the driver and the received dangerous driving history data according to the received dangerous driving history data and facial feature of the driver in the database, or establish a second mapping relationship between a facial feature of the driver that match the received facial feature of the driver and the received dangerous driving history data in the database.
After establishing the second mapping relationship between the facial feature of the driver and the dangerous driving history data in the database, and when the cloud platform receives the facial feature to be analyzed, the facial feature of the driver matching the facial feature to be analyzed may be determined in the database through feature comparison.
In the embodiment of the disclosure, the second dangerous driving history data acquired according to the second mapping relationship may represent a dangerous driving condition which the driver had experienced.
In the embodiment of the present disclosure, the third driving warning information may be used to indicate that a dangerous driving condition of the driver which is liable to appear at a future location of the vehicle. In practical applications, the first dangerous driving history data indicates a dangerous driving condition which had occurred at the future location of the vehicle, and the second dangerous driving history data indicates a dangerous driving condition which the driver had experienced, and therefore, a dangerous driving condition which the driver had experienced in the future location, i.e., the third driving warning information, may be obtained by comprehensively analyzing the first dangerous driving history data and the second dangerous driving history data.
In practical applications, after the cloud platform sends the third driving warning information to the vehicle, the vehicle may display the third driving warning information through the vehicle-mounted display screen, or broadcast the third driving warning information through voice.
It may be seen that, in the embodiment of the present disclosure, the third driving warning information may indicate that a dangerous driving condition of the driver which is liable to appear at a future location of the vehicle. Therefore, after receiving the third driving warning information, the vehicle may enable the driver of the vehicle to learn accurately and reliably that a dangerous driving condition would easily occur at the road ahead. It may be seen that the third driving warning information is the warning information for the actual driver of the vehicle, thereby facilitating the actual driver of the vehicle to take countermeasures in advance, and improving the safety of vehicle driving.
In an exemplary scenario, driver A sends a facial feature of driver A and a real-time location of the vehicle to a cloud platform when driving the vehicle. On the cloud platform, the second dangerous driving history data corresponding to driver A may be found based on the second mapping relationship, and the second dangerous driving history data indicates that driver A had ever had a behavior such as smoking, drinking, or making up. The first dangerous driving history data indicates that a behavior such as smoking, or drinking had occurred in the future location of the vehicle. By comprehensively analyzing the first dangerous driving history data and the second dangerous driving history data, the third driving warning information may be obtained. The third driving warning information is used to indicate that the driver is prone to behaviors such as smoking and drinking at a future location of the vehicle. In this way, after the vehicle receives the third driving warning information, the driver of the vehicle may learn accurately and reliably that the behaviors such as smoking and drinking would easily occur at the road ahead, thereby facilitating the driver of the vehicle to take countermeasures in advance, and improving the safety of vehicle driving.
In some optional embodiments of the present disclosure, the method for driving warning in the embodiment of the present disclosure may further include: receiving vehicle travel time information; determining third dangerous driving history data corresponding to the vehicle travel time information based on the third mapping relationship between the vehicle travel time information and the dangerous driving history data stored in the database; generating fourth driving warning information based on the first dangerous driving history data, the second dangerous driving history data, and the third dangerous driving history data; and sending the fourth driving warning information to the vehicle.
In the embodiment of the disclosure, the vehicle travel time information may represent at least one of: a time period within one day in which the current time at which the vehicle travels falls, a time period within one month in which the date on which the vehicle travels falls, a season within one year in which the month in which the vehicle travels falls, or the like. For example, when the current time at which the vehicle travels is 9.15 a.m., the time period within one day in which the current time at which the vehicle travels falls may be a time period from 9.00 a.m. to 10.00 a.m. When the date on which the vehicle travels is March 15, the time period within one month in which the date on which the vehicle travels falls may be the 10th day to the 20th day within one month. The foregoing is merely illustrative of the vehicle travel time information, and the embodiment of the disclosure is not limited thereto. In practical applications, the vehicle travel time information may be sent to the cloud platform by the vehicle-mounted device.
In some optional embodiments, before determining the third dangerous driving history data corresponding to the vehicle travel time information, the vehicle-mounted device provided in the vehicle may send the dangerous driving history data and the vehicle travel time information to the cloud platform. The cloud platform receives the dangerous driving history data and the vehicle travel time information sent by the vehicle-mounted device provided in the vehicle, and establishes a third mapping relationship between the received vehicle travel time information and the received dangerous driving history data in the database based on the received dangerous driving history data and vehicle travel time information. After the third mapping relationship is established in the database, and when the cloud platform receives the vehicle travel time information, the third dangerous driving history data corresponding to the received vehicle travel time information may be determined according to the third mapping relationship.
In the embodiment of the present disclosure, the third dangerous driving history data acquired according to the third mapping relationship may represent a dangerous driving condition, which had ever occurred, corresponding to the same vehicle travel time information. For example, the third dangerous driving history data may represent a dangerous driving condition that has occurred within the same time period of different dates, a dangerous driving condition that had occurred within the same time period of different months, a dangerous driving condition that has occurred within the same time period of different years, or the like.
In the present embodiment, the fourth driving warning information may be used to indicate that a dangerous driving condition of the driver which is liable to occur at a future location of the vehicle within the same time period. In practical applications, the first dangerous driving history data indicates a dangerous driving condition at the future location of the vehicle, the second dangerous driving history data indicates a dangerous driving condition which the driver has ever experienced, and the third dangerous driving history data indicates a dangerous driving condition, which has ever occurred, corresponding to the same vehicle travel time information, therefore, the dangerous driving condition at the future location of the vehicle within the same time period may be obtained through analyzing the first dangerous driving history data, the second dangerous driving history data, and the third dangerous driving history data are analyzed comprehensively. That is, the fourth driving warning information may be obtained.
In practical applications, after the cloud platform sends the fourth driving warning information to the vehicle, the vehicle may display the fourth driving warning information through the vehicle-mounted display screen, or broadcast the fourth driving warning information through voice.
It may be seen that, in the embodiment of the present disclosure, the fourth driving warning information may indicate that a dangerous driving condition of the driver which is liable to appear at a future location of the vehicle within the same time period. Therefore, after receiving the fourth driving warning information, the driver of the vehicle may accurately and reliably learn that a situation to the disadvantage of safe driving would easily occur ahead within the same time period. It may be seen that the fourth driving warning information is warning information for the actual driver of the vehicle and the same vehicle travel time information, thereby facilitating the actual driver of the vehicle to take countermeasures in advance, and improving the safety of vehicle driving.
In an exemplary scenario, driver B sends the facial feature of driver B, the vehicle travel time information, and the real-time location of the vehicle to the cloud platform when driving the vehicle. On the cloud platform, the second dangerous driving history data corresponding to driver B may be found according to the second mapping relationship. The second dangerous driving history data indicates that driver B has ever had a behavior such as smoking, drinking, or making up. The third dangerous driving history data corresponding to the vehicle travel time information may be found according to the third mapping relationship. The third dangerous driving history data indicates that a behavior such as smoking, drinking, or the like, is likely to occur within the same time period. The first dangerous driving history data indicates that a behavior such as smoking or drinking has ever occurred at a future location of the vehicle. By comprehensively analyzing the first dangerous driving history data, the second dangerous driving history data, and the third dangerous driving history data, a fourth driving warning information may obtained. The fourth driving warning information is used to indicate that a driver is prone to a behavior such as smoking and drinking at a future location of a vehicle within the same time period. In this way, after the vehicle receives the fourth driving warning information, the driver of the vehicle may accurately and reliably learn that the behavior such as smoking and drinking would easily occur ahead during the same period of time, thereby facilitating the driver of the vehicle to take countermeasures in advance, and improving the safety of vehicle driving.
In some optional embodiments of the present disclosure, the method for driving warning in the embodiments of the present disclosure may further include: receiving a vehicle identifier sent by a vehicle-mounted device; determining fourth dangerous driving history data corresponding to the vehicle identifier based on a fourth mapping relationship between the vehicle identifier and the dangerous driving history data stored in the database; generating fifth driving warning information based on the first dangerous driving history data and the fourth dangerous driving history data; and sending the fifth driving warning information to the vehicle.
In the embodiment of the present disclosure, the vehicle identifier may be a license plate number or other identifier information of the vehicle. In practical applications, the vehicle-mounted device may send the vehicle identifier to the cloud platform.
In some optional embodiments, prior to determining the fourth dangerous driving history data corresponding to the vehicle identifier, the vehicle-mounted device provided on the vehicle may send the dangerous driving history data and the vehicle identifier to the cloud platform, the cloud platform receives the dangerous driving history data and the vehicle identifier sent by the vehicle-mounted device provided on the vehicle, and establishes a fourth mapping relationship between the received dangerous driving history data and the received vehicle identifier in the database based on the received dangerous driving history data and the vehicle identifier. After establishing the fourth mapping relationship between the vehicle identifier and the dangerous driving history data in the database, and when the cloud platform receives the vehicle identifier, the fourth dangerous driving history data corresponding to the vehicle identifier may be determined in the database.
In the embodiment of the disclosure, the fourth dangerous driving history data acquired according to the fourth mapping relationship may represent a dangerous driving condition which has ever occurred to the vehicle.
In the embodiment of the present disclosure, the fifth driving warning information may be used to indicate a dangerous driving condition which is liable to occur to the vehicle at a future location. In practical applications, the first dangerous driving history data indicates a dangerous driving condition which has ever occurred at a future location of the vehicle, and the fourth dangerous driving history data indicates a dangerous driving condition which has ever occurred to the vehicle, therefore, by comprehensively analyzing the first dangerous driving history data and the fourth dangerous driving history data, a dangerous driving condition which is liable to occur to the vehicle at a future location may be obtained. That is, the fifth driving warning information may be obtained.
In practical applications, after the cloud platform sends the fifth driving warning information to the vehicle, the vehicle may display the fifth driving warning information through the vehicle-mounted display screen, or may broadcast the fifth driving warning information through voice.
It may be seen that, in the embodiment of the present disclosure, the fifth driving warning information may indicate a dangerous driving condition which is liable to occur to the vehicle at a future location. Therefore, after the vehicle receives the fifth driving warning information, the driver of the vehicle may accurately and reliably learn that a situation to the disadvantage of safe driving would easily occur ahead. It may be seen that the fifth driving warning information is the warning information for the vehicle, thereby facilitating the driver to take countermeasures in advance, and improving the safety of vehicle driving.
In an exemplary scenario, vehicle A sends the identifier of vehicle A and the real-time location of the vehicle to the cloud platform during the travel. On the cloud platform, the fourth dangerous driving history data corresponding to vehicle A may be found based on the fourth mapping relationship. The fourth dangerous driving history data indicates that vehicle A has ever experienced a travel behavior such as lane departure, forward collision, or overspeed. The first dangerous driving history data indicates that a travel behavior such as lane departure or forward collision has ever occurred at a future location of the vehicle. A fifth driving warning information is obtained by comprehensively analyzing the first dangerous driving history data and the fourth dangerous driving history data. The fifth driving warning information is used to indicate that the vehicle is liable to experience a travel behavior, such as lane departure or forward collision, at a future location. In this way, after vehicle A receives the fifth driving warning information, the driver of the vehicle may accurately and reliably learn that the travel behavior such as lane departure or forward collision is liable to occur to vehicle A, thereby facilitating the driver of the vehicle to take countermeasures in advance, thereby improving the safety of vehicle driving.
In some optional embodiments of the present disclosure, the method for driving warning in the embodiments of the present disclosure may further include: receiving vehicle travel time information; determining third dangerous driving history data corresponding to the vehicle travel time information based on the third mapping relationship between the vehicle travel time information and the dangerous driving history data stored in the database; generating sixth driving warning information based on the first dangerous driving history data, the third dangerous driving history data, and the fourth dangerous driving history data; and sending the sixth driving warning information to the vehicle.
In the embodiment of the present disclosure, the sixth driving warning information may be used to indicate a dangerous driving condition which is liable to occur to the vehicle at a future location within the same time period. In practical applications, the first dangerous driving history data indicates a dangerous driving condition which has ever occurred to the vehicle at a future location, the second dangerous driving history data indicates a dangerous driving condition which has ever occurred to a driver, and the third dangerous driving history data indicates a dangerous driving condition, which has ever occurred, corresponding to the same vehicle travel time information. The fourth dangerous driving history data indicates a dangerous driving condition which has ever occurred to the vehicle. Therefore, by comprehensively analyzing the first dangerous driving history data, the third dangerous driving history data, and the fourth dangerous driving history data, a dangerous driving condition which has ever occurred to the vehicle at a future location within the same time period may be obtained. That is, the sixth driving warning information may be obtained.
In practical applications, after the cloud platform sends the sixth driving warning information to the vehicle, the vehicle may display the sixth driving warning information through the vehicle-mounted display screen, or broadcast the sixth driving warning information.
It may be seen that, in the embodiment of the present disclosure, the sixth driving warning information may indicate a dangerous driving condition which is liable to occur to the vehicle at a future location within the same time period. Therefore, after the vehicle receives the sixth driving warning information, the driver of the vehicle may accurately and reliably learn that a situation to the disadvantage of safe driving would easily occur ahead within the same time period.
