The main execution body of the present invention is a device with a data processing function, which may be a processor or a server, and this is within the scope of the present invention. The execution main body can be arranged inside the output device or arranged outside and connected with the output device, and the protection scope of the invention is also included.

When the current navigation information is output, the current navigation information can be output through an output device.

the identity information of the user may be: one or more of a mobile phone number, a user name, face information, fingerprint information, voice information, and the like.

different identity information is acquired in different modes. For a mobile phone number and a user name, a user can identify the identity of the user only by logging in a system through the mobile phone number or the user name, and then identity information of the user is obtained.

for the face information, a face recognition device needs to be installed on the vehicle, and the identity information of the user is recognized through the face recognition device. For the fingerprint information, a fingerprint recognition device needs to be installed on the vehicle to recognize the fingerprint information of the user. For the voice information, it is necessary to install a voice recognition device on the vehicle to recognize the voice information of the user.

Wherein the current state information of the vehicle may include: the current position information of the vehicle, the usage time of the vehicle, mileage, remaining fuel (remaining amount of electric vehicle), engine temperature, tire status, current driving status, whether the user gets on the vehicle, the place and time when the user gets on the vehicle, etc. The current position information may be obtained by a positioning device, such as a GPS, a beidou positioning system, or the like. The brand of the vehicle reserves an interface for the output device or the output device is built in the vehicle by the brand, and the state information of the vehicle can be obtained.

The real-time traffic information can be obtained through map software built in the execution main body.

Wherein, the current navigation information may include: one or more of a destination address, a travel route, a special address, a special action, etc.

The address is a gas station, a 4S store, or the like. The special actions refer to rest, refueling, car repair, annual audit and the like.

Before the step of inferring the current navigation information of the vehicle based on the pre-established knowledge graph according to the identity information, the current state information of the vehicle and the real-time road condition information, the method may further include: acquiring one or more information of identity information of a user, basic information of the user, basic information of output equipment, driving data of the current user and driving data of other users; and establishing a knowledge graph according to the acquired information.

The collected user identity information may include: one or more of a mobile phone number, a user name, face information, fingerprint information, voice information, and the like. The collected user basic information may include: home address, office address, common address, license plate number, vehicle type, annual audit time, driving license type, driving license time limit, etc.

The basic information of the output device may include: the software and hardware version of the output device, the access map version of the output device and the functional state of the output device (whether the information such as GPRS, networking and the like is normal or not).

the current user's driving data may include: basic information of the vehicle; historical navigation information of the vehicle, etc.

The basic information of the vehicle may include: the type of the vehicle, the type of the part, the total mileage, the service time and the like.

Wherein the historical navigation information of the vehicle may include: counting the time point and times of taking a certain address as a starting place; counting the time point and times of taking a certain address as a destination; departure and arrival time points, time lengths, congestion conditions, fuel consumption speed and the like from a departure place to a destination.

The travel data of other users may include: selecting a driving route under the same external conditions; information such as recommendation and evaluation for a place such as a 4S store and a gas station; fuel consumption speed, tire risk factor, etc. of different vehicle types.

After the information is collected, a knowledge graph can be established according to the collected information. The established knowledge graph can comprise two knowledge graphs, wherein one knowledge graph takes user identity information as a core node; the other is a generic knowledge graph.

when the knowledge graph with the user identity information as the core node is established, the knowledge graph with the user identity information as the core node can be established according to the identity information of the user, the basic information of the output equipment, the driving data of the current user and the like as the knowledge node.

when the general knowledge graph is established, firstly, statistical analysis is carried out on the collected driving data of the current user and the driving data of other users to obtain an analysis conclusion, and an analysis result is stored in a knowledge graph form to form the general knowledge graph.

For example, the generic knowledge graph stores: the tire burst probability is high when the tire pressure of the vehicle type A is X; the vehicle can continuously run for 100 kilometers when the mileage is ten thousand of the vehicle type A and 1/3 tanks of oil are left; when the speed per hour exceeds Y, the vehicle type A has a high probability of rollover.

In the invention, the collected driving data of other users can be a series of table data, and the statistical analysis process is to extract relevant columns for statistics, calculate the probability of each situation and the threshold condition, and then store the calculated probability and threshold condition into the general knowledge map. And when detecting that the corresponding measured value of the real-time vehicle condition of the user reaches a threshold condition, prompting the user or automatically adjusting the vehicle setting.

Before the user formally starts driving or in the driving process, the information of the vehicle condition, the driving license validity and the like of the user is detected in real time, and if the information is abnormal, the user is reminded or the line is switched and the like. The prompt information for prompting the user may include: annual inspection time, over-high mailbox temperature, less oil mass, over-high water tank temperature, over-high temperature in the vehicle, over-long driving time and the like.

In this way, the special address and the special action can be intelligently recommended to the user, and the user experience is further improved.

For example: monitoring the temperature of the water tank in real time in the driving process of a user, and if the temperature of the water tank exceeds a corresponding threshold condition, sending prompt information to the user; and monitoring the temperature in the vehicle in real time, and sending prompt information to a user if the temperature in the vehicle exceeds a corresponding temperature threshold condition.

For example, when the current remaining fuel amount of the vehicle is one third of the fuel amount, the general knowledge map and the position information of the gas station are combined to recommend a driving route for the user, so that the user can timely refuel the vehicle.

For example: when the continuous driving time of the user is longer and exceeds the preset driving time, the driving over-long reminding information and the reminding user rest information are sent to the output equipment, and the output equipment outputs corresponding reminding information to the user.

For example: when the temperature of the engine is higher and exceeds the preset temperature, current engine temperature information, over-temperature reminding information, rest reminding information of a user and the like are sent to the output equipment, and the output equipment outputs corresponding reminding information to the user.

When the knowledge graph is established, a plurality of triples can be established according to the acquired information and stored in a triplet form to form the knowledge graph. When the knowledge graph is established, one knowledge graph with user identity information as a core node can be established, or a plurality of knowledge graphs can be established; one general knowledge graph can be established, and a plurality of general knowledge graphs can be established according to functional use, which are all within the protection scope of the invention.

In the invention, after the identity information of the user, the current state information of the vehicle and the real-time road condition information are acquired, the current navigation information such as the destination address and the optimal driving route of the user can be deduced according to the time and the place of the user getting on the vehicle.

and after the user confirms, the driving data of the current user in the knowledge map and the road condition displayed by the map in real time are combined to recommend a driving route for the user. Wherein, the driving data of the current user may include: departure and arrival time points, time lengths, congestion conditions, and the like from a departure place to a destination in the history navigation information.

In the invention, the destination address of the user can be deduced, the destination address input by the user can also be accepted, and the user can input the destination address in a voice mode, a character mode and the like. All within the scope of the invention.

when the destination address and the starting address are addresses that the user has walked before, a route can be recommended for the user according to the knowledge graph with the user identity information as the core node.

and when the user does not walk through the destination address and the starting address, recommending a route for the user according to the destination address, the starting address, the time point and the current road condition.

In the present invention, common routes, such as travel routes between famous, landmark points, may also be stored in the universal knowledge graph. And obtaining a common route by performing statistical analysis on the driving data of all users, and storing the common route into the general knowledge map.

And when the destination address or the starting address is an identified and famous place and the driving routes of the two places are stored in the general knowledge map, recommending the route for the user according to the general knowledge map and the current road condition.

And when the route from the destination address to the initial address is not searched in the knowledge graph, a statistical analysis method is adopted to statistically analyze the driving routes from the destination address to the initial address of other users, and the route is recommended for the user by combining the current road condition.

In the invention, the destination address can be modified at any time when the user drives the vehicle, and after receiving the new destination address set by the user, the driving route can be recommended for the user according to the established knowledge map and the real-time road condition information.

In a specific embodiment provided by the present invention, the method may further include: receiving a position query signal transmitted by intelligent equipment; and outputting the current position information of the vehicle and the inquiry route to the intelligent equipment according to the position inquiry signal.

in the invention, a location query signal sent by the intelligent device can be received, wherein the intelligent device can be an electronic device carried by a user, such as a mobile phone. When the vehicle is parked in a parking lot or other place, the user can inquire the position of the vehicle through the intelligent device carried with the user. When the execution subject receives the position inquiry signal, the current position information of the vehicle and the inquiry route from the user to the vehicle can be output to the intelligent device. When the current location information and the query route are displayed, they may be displayed for the user in various ways. Thus, the user can easily find the vehicle when the user parks the vehicle in a remote place.

In a specific embodiment provided by the present invention, the output device employs a virtual robot, a physical robot, or the like.

When the current navigation information is output, the robot output of the virtual character can be adopted, and the driving suggestion can be vividly provided for the user through holographic or other technical means.
