Description

Method and apparatus for customized information push for vehicle

Technical Field

The present invention relates to a method for customized information push for a vehicle and an apparatus for customized information push for a vehicle.

Background

With the development of internet of vehicles technology, more and more vehicles are equipped with automated driving functions, however, the vehicles commonly found on the market today are still not intelligent in some respects. For example, it is still impossible for the vehicle itself to provide customized reminders and/or suggestions to the user based on where the vehicle is currently located to provide a final personalized experience.

Currently, value added services Based on LBS technology (Location Based Service) are proposed in the prior art, and the technology is generally applied to mobile terminal users, and obtains Location Information of the mobile terminal users Based on a radio communication network (such as a GSM network and a CDMA network) of a telecom and a mobile operator or an external Location mode (such as a GPS), and provides corresponding services for the users under the support of a GIS (Geographic Information System) platform.

However, the information push method based on the network operator exposes the privacy of the user to a certain extent, and the technology strongly depends on an active check-in mode to acquire the geographic position of the user in some cases, so that high requirements are placed on the behavior of the user. In addition, the positioning method based on GPS requires that the vehicle must be equipped with a navigation positioning tool with high specification, and the performance of the positioning method in terms of positioning accuracy is poor.

Disclosure of Invention

The present invention is directed to a method for customized information push for a vehicle and an apparatus for customized information push for a vehicle, which solve at least some problems of the prior art.

According to a first aspect of the present invention, a method for customized information push for a vehicle is presented, the method comprising the steps of:

s1: acquiring the geographical position of the vehicle by means of a low-power Bluetooth technology;

s2: generating customized information associated with at least the geographic location; and

s3: and pushing the customized information to a vehicle user.

The invention comprises in particular the following technical concepts: compared with a conventional Bluetooth device, a BLE (Bluetooth Low Energy) device does not need to be paired before transmitting and receiving a signal, and thus can acquire position information from a BLE beacon around a vehicle at a lower cost and with user privacy secured. Furthermore, modern vehicles have mostly been equipped with bluetooth modules supporting the BLE protocol automatically, which are able to send and receive data regularly with very low energy consumption, so that the determination of the geographic position can be easily achieved irrespective of whether the vehicle has advanced navigation functions or the latest version of map data, and thus personalized information is provided to the vehicle user.

Optionally, step S1 includes: receiving a broadcast signal from at least one BLE module disposed at an infrastructure in a surrounding environment of a vehicle, the broadcast signal including a geographic location of the infrastructure; determining the precise geographical location of the vehicle based on triangulation and from signal strength of the broadcast signal, and/or determining the geographical location of the infrastructure directly as the geographical location of the vehicle.

Therefore, the BLE beacons are easy to deploy in a large scale due to low power consumption and small size, so that when the position of the vehicle is identified, the high precision requirement of single-point positioning can be achieved through the densely deployed BLE beacons, and the precise geographic position of the vehicle can be obtained based on further analysis and calculation when necessary. Therefore, the positioning precision of the vehicle is flexible and adjustable, and the information pushing requirements of different grades are met.

Optionally, step S1 includes: receiving shared information from a BLE module of at least one other vehicle in the vehicle's surroundings, the shared information including a geographic location of the at least one other vehicle; determining the geographic location of the at least one other vehicle as the geographic location of the vehicle

Therefore, vehicle position sharing is achieved in a simple mode through vehicle-to-vehicle communication, and deployment cost of the BLE beacon can be reduced to a certain extent.

Optionally, step S2 includes: in response to the obtained geographic location, customized information matching the geographic location is requested from a server and/or recalled from memory.

Therefore, online acquisition and local acquisition of the customized information are advantageously realized, and a more flexible information pushing scheme is provided.

Optionally, the method further comprises: providing basic information of a vehicle, which is taken into account in step S2 such that the generated customized information is adapted to the basic information of the vehicle, wherein the basic information of the vehicle comprises in particular at least one of the following: model, brand, manufacturer, year of delivery, and vehicle configuration information of the vehicle. Providing vehicle configuration information may also enable a service provider to provide more advanced personalized services in certain situations (e.g., when the vehicle arrives at the location of an authorized vehicle accessory or service dealer).

Therefore, the customized information is generated by taking the current geographic position of the vehicle into consideration and taking the basic information of the vehicle as an influence factor into consideration, so that the effect of personalized customization is fully achieved. In addition, since the vehicle basic information only relates to general information such as vehicle signals and manufacturers, personal privacy data of a vehicle user cannot be leaked even in extreme cases, and data security is guaranteed.

Optionally, the method further comprises: the activity state information and/or the vehicle state information of the vehicle user is provided, and the activity state information and/or the vehicle state information of the vehicle user is considered in step S3 such that the customized information is pushed to the vehicle user only when the activity state information and/or the vehicle state information of the vehicle user satisfies a predetermined condition.

Therefore, the trigger condition for customizing information pushing can be further filtered by considering the activity state and the vehicle state of the vehicle user, and the unreasonable information pushing time and the interference of excessive irrelevant information pushing on the vehicle user can be effectively avoided.

Optionally, the method further comprises: a timestamp is assigned to the obtained geographic location.

Therefore, the time of the vehicle reaching a specific geographic position can be additionally considered in addition to the space limit when the customized information is generated, so that a time limit condition is established for the triggering of the customized information, and the customized information is more in line with the requirements of users.

Optionally, the method further comprises: a user identity identifier is assigned to the obtained geographical location.

Therefore, the push condition can be triggered only when the vehicle-mounted machine system of the vehicle logs in a specific user. For example, on the premise that the user a logs in at the driver location, if the obtained geographic location is only bound to the identity of the user C, the vehicle will receive a customized message push on that device only when logging in the account of the user C at any location of the vehicle (e.g., a front passenger seat or a rear left location, etc.), and other users will not receive corresponding message pushes. This is particularly advantageous for vehicles with multiple entertainment interaction systems in different locations.

Optionally, the method further comprises: the method comprises the steps of obtaining a user-defined geographic position and user-defined customized information of a vehicle user, and pushing the user-defined customized information to the vehicle user when the vehicle is detected to reach the user-defined geographic position by means of a low-power-consumption Bluetooth technology.

Therefore, support can be provided for the customized information triggering mechanism based on the third-party service provider and the information database compiled locally in the system in advance, and the customized information triggering mode of the vehicle user can be followed, so that the style and habit of customized information pushing can better meet the user requirements, and the satisfaction degree is improved. In addition, the propagation and sharing of the custom information can be realized especially by combining a block chain and a big data platform, so that the richness of the custom information database is realized at lower cost.

Optionally, in order to obtain the geographical position of the vehicle by means of bluetooth low energy technology, data transmission is carried out between the vehicle and a BLE module arranged at an infrastructure in the surroundings of the vehicle in an encrypted communication, wherein in particular the key of the encrypted communication is changed at certain time intervals.

Optionally, the customized information may also be generated based on a history of the obtained geographic locations. By the arrangement, the government can take over and access the system in special periods such as epidemic situations, flood disasters, earthquakes or wartime. Therefore, the functions of sign-in and reminding can be effectively and seamlessly completed on the premise of protecting the privacy of the user to the maximum extent. The private secret message prompt can be provided for vehicles and users who visit a specific area within a specific time range, so that the customers can reduce the trips or avoid the contact with the outside, and the like.

The information content is advantageously masked by the encryption operation during the data exchange process, thereby further improving the reliability of information transmission.

According to a second aspect of the present invention, a device for customized information push for a vehicle is presented, the device being adapted to perform the method according to the first aspect of the present invention, the device comprising:

a communication module configured to enable acquisition of a geographic location of a vehicle by means of bluetooth low energy technology;

a processor module configured to enable generation of customization information associated with at least the geographic location; and

a push module configured to be able to push the customization information to a vehicle user.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.

Fig. 1 shows a block diagram of an apparatus for customized information push for a vehicle according to an exemplary embodiment of the present invention.

As exemplarily shown in fig. 1, the device 10 includes a push module 14, a processor module 15, and a communication module 16. The communication module 16 may be configured as a separate BLE tag module so that data may be exchanged with BLE beacons in the surrounding environment based on bluetooth low energy technology, it is also possible that the communication module 16 is part of a bluetooth module supporting the BLE communication protocol that is originally present in the vehicle. After acquiring the geographic location, the communication module 16 may transmit the geographic location to the processor module 15, where the processor module 15 may optionally determine the received geographic location directly as the geographic location of the vehicle, or may further calculate the precise geographic location of the vehicle based on triangulation in conjunction with information such as the ID, signal strength, etc. of the BLE beacon received at the same time.

In this embodiment, the device 10 further comprises a memory module 17 and a further communication module 18. In the memory module 17, a plurality of predefined customization information is stored, which in particular correspond to different geographical triggering conditions. Once it is determined in the processor module 15 that the acquired geographical location satisfies the trigger condition, the processor module 15 invokes the corresponding customization information from the memory module 17. It is also possible that the customization information associated with the geographic location is stored in a server (e.g., of a third party service provider), and in response to receiving the geographic location, the processor module 15 may request the corresponding customization information from the server via the further communication module 18, e.g., based on a further wireless communication protocol (e.g., WiFi, cellular network communication).

The processor module 15 is also connected to the push module 14 for transmitting the generated customization information to the vehicle user via the push module 14. The push module 14 may be configured as a user interface and is exemplarily connected to at least one actuator 11-13, which may be a loudspeaker 11, a display 12, a navigation device 13, etc., so that the customized information can be presented to the user, for example in the form of audio, video, text, images. Illustratively, the pushed customization information may be an execution recommendation for at least one function of the vehicle, a selection recommendation for at least one destination, a display recommendation for at least one audio/video content, a presentation recommendation for advertising information. In response to a user's trigger operation (e.g., a selected operation) with respect to the customization information, an operation associated with the customization information may be performed.

Figure 2 shows a schematic diagram of acquiring the geographical position of a vehicle by means of BLE technology according to an exemplary embodiment of the invention.

In the embodiment of figure 2, the BLE beacon 21 is arranged at the infrastructure 25 and broadcasts to the surroundings a message containing the geographical location of the infrastructure 25. Illustratively, the BLE beacon 21 has a determined signal coverage and thereby forms a fixed size electronic fence 22 around the infrastructure 25. When the vehicle 20 including the device 23 in fig. 1 approaches the infrastructure 25 and enters the electronic fence 22, the communication module 24 of the device 23 may receive the message transmitted by the BLE beacon 21 and obtain the geographic location contained therein by using bluetooth low energy technology. The device 23 may then update the geographical position of the vehicle to the received geographical position.

By way of example, the vehicle 20 can also communicate via the device 23 with another vehicle 27 in its vicinity, which other vehicle 27 likewise has a device 28 as shown in fig. 1. Thus, the geographic location of the vehicle 27 is shared with the vehicle 20.

In addition, the vehicle 20 may also communicate with a server 26 (e.g., disposed in the cloud) via the device 23 to request from the server 26 or recall from a database in the cloud customized information associated with the current geographic location of the vehicle 20.

Here, depending on the type of server 26, a passive firing mode and an active invocation mode of the customized information may be involved. In the case where the server 26 is a server of a third party service provider, the automatic answer mechanism may be triggered as soon as the vehicle enters the signal coverage of the BLE beacon 21, that is, in response to receiving the ID information or geographical location information broadcast by the BLE beacon 21, the device 23 may automatically request service information matching the ID information or geographical location information from the server 26. Here, the customized information returned to the vehicle 20 may be, inter alia, advertisement information or promotion information delivered by a third party service provider.

In the case where the server 26 is a general internet server, the device 23 may actively search and download information about the acquired geographical location, which may be, for example, introductory information of tourist attractions, entrance ticket information of museums, opening time information of restaurants, and the like, from the server 26 based on the geographical location, whereby diverse information conforming to the present scene may be pushed to the vehicle user.

Fig. 3 shows a schematic diagram of customized information push for a vehicle user in a parking lot according to an exemplary embodiment of the present invention.

In the large parking lot shown in fig. 3, a plurality of

BLE beacons

33, 35 are arranged at

different parking areas

31, 32. After the vehicle 30 equipped with the apparatus shown in fig. 1 enters the parking lot, the vehicle 30 receives the signal broadcast-transmitted by the BLE beacon 33 closest to its current position, and thereby recognizes that the vehicle 30 itself has arrived at the parking lot. Based on this, vehicle 30 may automatically request the customized information associated with the current location from parking server 34. As predefined responsive feedback, parking lot server 34 may transmit an electronic plan view of the parking lot to vehicle 30 and note the current geographic location of vehicle 30 thereon.

When the vehicle 30 approaches the parking area 31 with the BLE beacon 33, not only the message content transmitted by the BLE beacon 33 may be received and decoded on the vehicle 30 side, but also the vehicle basic information transmitted by the vehicle 30 may be received and decoded by the BLE beacon 33, so as to use the vehicle basic information to trigger more personalized information delivery. Here, the BLE beacon 33 may further transmit the vehicle basic information to the parking lot server 34.

Through this information exchange, the parking lot server 34 not only knows the geographical position of the vehicle 30 but also the specific model of the vehicle 30, whereby the parking lot server 34 can recommend the exclusive parking area 32 in a particularly suggested form in combination with the specific model of the vehicle 30, in addition to pushing an electronic plan of the parking lot to the vehicle 30.

After determining the exclusive parking area 32 for the vehicle 30, the floor and the number of the exclusive parking area 32 may be popped up on the screen of the vehicle 30. Further, as the vehicle 30 advances in the parking lot, the device (not shown) of the vehicle 30 for customized information push continuously recognizes the signal of the nearest BLE beacon and updates the geographic position of the vehicle on the electronic plan view, whereby the guidance route of the vehicle 30 to the target position 32 can be matched out from the route database and marked out in the map. During the driving of the vehicle 30, the vehicle 30 continuously scans the broadcast information of BLE beacons at different locations, for example, based on bluetooth low energy technology, and thus dynamically refreshes the current location and the guidance route in the electronic plan.

In step 401, a message broadcasted by a BLE beacon loop arranged at an infrastructure is received, the message comprising, for example, a geographical location of the infrastructure and a secret key.

In step 402, the message is decrypted by means of a key in the message or a specific decryption algorithm.

The geographical position contained in the message may then be extracted and determined as the geographical position where the vehicle is currently located in step 403.

As an example, the information associated with the geographic location is written and stored in a local memory of the vehicle, for example, as predefined information. In response to the current geographic location of the vehicle, information associated with the geographic location may be recalled from memory in step 404. In the case where the geographic location is a gas station, such information associated with the geographic location may be, for example, recommended operation information of "reset odometer", thereby facilitating the vehicle user to re-make the mileage record in a new driving cycle after the odometer clearing operation.

Optionally, activity status information of the vehicle user and/or vehicle status information may also be provided in step 405.

In step 406, it is determined whether the information push condition is satisfied in connection with the geographic location of the vehicle, the activity status of the vehicle user, and/or the vehicle status.

If the information push condition is not met, then no information push is selected in step 407 and the process returns to step 405 again to continue monitoring the activity status of the vehicle user and/or the vehicle status. For example, in a case where the vehicle recognizes that it has arrived at a gas station based on the bluetooth low energy technology, if the vehicle state monitored at this time is "not in a flameout state", it indicates, for example, that the vehicle is not currently performing or is not ready to perform a refueling operation. The push condition of the information "reset odometer" called in step 404 is not satisfied.

If, on the other hand, it is determined in step 406 that the information push condition is satisfied, it may jump to step 408. Illustratively, if the vehicle status is detected as "off" in step 405, this indicates that the vehicle is likely to intend or is fueling, in which case the customized information suitable for pushing to the vehicle user is "whether to reset the odometer".

In step 408, basic information of the vehicle may be further provided to optimize the content of the customized information. For example, the model of the vehicle, the brand of the vehicle, the manufacturer, the year of factory, etc. may be provided.

Subsequently, in step 409, it may additionally be determined whether the first information push condition or the second information push condition is satisfied, taking into account the basic information of the vehicle.

Depending on the result of the above-described determination, the first customized information and the second customized information may be provided in

steps

410 and 411, respectively. For example, if the specific model of the vehicle is known in step 408, the fuel type (e.g., gasoline, diesel, natural gas, or hydrogen energy) and corresponding fuel model (e.g., gasoline 92# or 95#) adapted to the vehicle may be determined based thereon and optimized customization information pushed for the vehicle accordingly.

Although specific embodiments of the invention have been described herein in detail, they have been presented for purposes of illustration only and are not to be construed as limiting the scope of the invention. Various substitutions, alterations, and modifications may be devised without departing from the spirit and scope of the present invention.
