Three components are defined in the P2P architecture, which may be referred to as a device and two roles, where a device is referred to as a P2P device (P2P device), which is an entity of the role in the P2P architecture and may be regarded as a Wi-Fi device. Two roles refer to roles GO (group owner) and GC (group client), respectively, where GO acts like an AP in the infrastructure mode basic service set (infrastructure basic service set, infrastructure BSS), like a hotspot, allowing multiple GCs access. The GC acts like a Station (STA) in infrastructure BSS, but can only connect to one GO, and cannot connect to multiple goes.

Prior to the establishment of a P2P network, a plurality of communication devices may be considered P2P devices. After the P2P negotiation is completed among the P2P devices, only one P2P device can perform the corresponding function as the GO role, and the other P2P devices perform the corresponding function as the GC roles.

2. Interconnection of mobile phone and car

When the mobile phone is connected with the vehicle, a user can connect a data line with a vehicle universal serial interface (universal serial bus, USB) port, or can start the system by clicking a vehicle interconnection application of a vehicle application program (APP) connection interface through wireless connection. A user using the vehicle-mounted internet application can safely and quickly use rich applications in the driving process by connecting the mobile phone to the vehicle-mounted system through a data line or Wi-Fi without paying attention to what operating system the smart mobile phone is. The main functions at present are map navigation, voice, music, telephone, etc.

3. Other terms

In the embodiment of the application, the words "first", "second", etc. are used to distinguish identical items or similar items having substantially the same function and action, and the sequence thereof is not limited. It will be appreciated by those of skill in the art that the words "first," "second," and the like do not limit the amount and order of execution, and that the words "first," "second," and the like do not necessarily differ.

In the present application, the words "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

Furthermore, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, and c may represent: a, b, or c, or a and b, or a and c, or b and c, or a, b and c, wherein a, b and c can be single or multiple.

The "at … …" in the embodiment of the present application may be an instant when a certain situation occurs, or may be a period of time after a certain situation occurs, which is not particularly limited. In addition, the display interface provided by the embodiment of the application is only used as an example, and the display interface can also comprise more or less contents.

When a general user connects a mobile phone with a vehicle supporting a certain type of vehicle-to-vehicle interconnection protocol, the problem of poor usability caused by no operation during first use, complex multi-terminal operation flow of the mobile phone and the vehicle-to-vehicle, and large difference of connection flow of different brands of vehicle-to-vehicle is possibly solved.

The wireless connection modes which can be supported by the vehicle-to-machine interconnection protocol at present comprise a connection mode based on a Wi-Fi hotspot of a mobile phone and a connection mode based on Wi-Fi P2P, different brands of vehicle-to-machine or the same brand of vehicle-to-machine in different periods can adopt different connection modes, and the connection steps of the different connection modes are different. It may not be clear to the user which connection mode the vehicle supports. Even if the connection mode is known, the steps of the common connection are complicated, the operability is very unfriendly for novice users, and finally, the interconnection of the mobile phones and locomotives can be abandoned.

For example, when a user who wants to experience a wireless connection mode uses a car machine supporting the wireless connection mode, the user is usually required to search a multi-layer directory in the setting of the mobile phone to find a connection instruction, and the connection instruction is further classified into a Wi-Fi hotspot connection instruction and a WLAN (Wi-Fi P2P) connection instruction. After the type of the connection instruction is selected, the user enters a corresponding connection instruction interface, and then the wireless connection can be completed only by carrying out multi-step operation on the two ends of the mobile phone and the vehicle machine according to the connection instruction. Taking a connection mode based on a mobile phone Wi-Fi hotspot as an example, the method can comprise the following steps:

step one: at the mobile phone end, a user opens a personal hot spot at the mobile phone end; at the vehicle terminal, a user opens a Wi-Fi setting page of the vehicle and is connected with a mobile phone hotspot. When the car machine is connected with the mobile phone hotspot, the user needs to search the account number and the password of the mobile phone hotspot, so that the user needs to search in the mobile phone, and the user is not easy to get on hand for some users.

Step two: at the vehicle machine end, a user confirms the name of the Bluetooth of the vehicle machine; at the mobile phone end, a user is manually connected with the car Bluetooth.

Step three: the user clicks the vehicle-machine interconnection application of the vehicle-machine end. The user then confirms that the above operation starts the connection.

In some cases, even if the user succeeds in connecting according to the connection guidance, the connection mode may not be optimal as selected by the user. For example, the car machine supports a connection mode based on a Wi-Fi hot spot of the mobile phone and a connection mode based on Wi-Fi P2P at the same time, but a user selects the connection mode based on the Wi-Fi hot spot of the mobile phone, however, the power consumption of the mobile phone due to the connection mode based on the Wi-Fi hot spot of the mobile phone is higher than that of the mobile phone due to the connection mode based on Wi-Fi P2P, and the duration of the mobile phone is shortened.

Based on the analysis, the existing connection mode needs excessive participation of users, and the problems of high connection professionality and complicated operation steps of the mobile phone and the car phone prevent the users from obtaining good use experience.

In view of the above, the embodiment of the application provides a method for connecting a vehicle and a machine, which can automatically perform wireless connection based on the requirement of a user on interconnection of a mobile phone and the vehicle and machine, firstly try a connection mode based on Wi-Fi P2P, then try a connection mode based on Wi-Fi hot spots of the mobile phone, and prompt the user to perform manual connection under the condition that connection of the two wireless modes fails, so that the user does not need to select the wireless connection mode, the operation of the user is reduced as much as possible in the connection process, the convenience of interconnection of the mobile phone and the vehicle and machine is improved, and the learning cost of the user is reduced.

In the following embodiment, a mobile phone is taken as an example of a terminal device, and an internal interaction flow chart of the mobile phone and the vehicle-to-vehicle interconnection is described in conjunction with fig. 3.

Fig. 3 is a schematic flow chart of a method for connecting a vehicle machine according to an embodiment of the present application. As shown in fig. 3, the system for implementing the method for connecting the vehicle device includes a mobile phone and a vehicle device, and the mobile phone may have the structure shown in fig. 1 and fig. 2, but the embodiment of the application is not limited thereto. The mobile phone and the car machine can comprise various functional modules for realizing the method for connecting the car machine, such as a Bluetooth module, a Wi-Fi P2P module, a car machine interconnection protocol and the like.

For convenience of description, the vehicle-to-machine interconnection protocol of the mobile phone is referred to as a first vehicle-to-machine interconnection protocol, the Wi-Fi P2P module of the mobile phone is referred to as a first Wi-Fi P2P module, the bluetooth module of the mobile phone is referred to as a first bluetooth module, and the mobile phone further comprises a Wi-Fi hotspot module and travel service. The Bluetooth module of the vehicle is called a second Bluetooth module, the vehicle-to-vehicle interconnection protocol of the vehicle is called a second vehicle-to-vehicle interconnection protocol, the Wi-Fi P2P module of the vehicle is called a second Wi-Fi P2P module, and the vehicle further comprises a Wi-Fi STA module.

The method for connecting the vehicle machine provided by the embodiment of the application can be divided into three stages, wherein the first stage is Bluetooth connection, the second stage is Wi-Fi P2P connection and the third stage is Wi-Fi hot spot connection. The stages are described separately below in connection with fig. 3.

First stage, bluetooth connection.

When the travel service of the mobile phone monitors some user behaviors, the travel service can send a Bluetooth search instruction to the first Bluetooth module to instruct the first Bluetooth module to find nearby Bluetooth equipment, and identify a target vehicle-mounted Bluetooth which is expected to be connected by a user of a driver from at least one nearby Bluetooth equipment. The user behavior may include an operation of enabling the vehicle-to-machine interconnection by a user in an interface of the travel service, or an operation of connecting the vehicle-to-machine by a user voice instruction. The specific monitored user behavior can be set by the trip service in a self-defined manner, and the embodiment of the application is not limited to the specific monitored user behavior.

In order to accurately identify the target bluetooth of the user, the mobile phone needs to solve the following two problems:

problem one: how to judge that the searched Bluetooth device is a vehicle Bluetooth device, not a Bluetooth device such as a Bluetooth earphone, a Bluetooth watch and the like.

And a second problem: how to judge that the searched vehicle-mounted Bluetooth is the vehicle-mounted Bluetooth of the vehicle where the user is currently located.

Aiming at the problems, the existing scheme does not recognize the vehicle-mounted Bluetooth, the vehicle-mounted equipment can be recognized as audio equipment, and then a user selects the target vehicle-mounted Bluetooth from at least one vehicle-mounted equipment recognized as the audio equipment.

As an optional embodiment, the mobile phone responds to the operation of connecting the mobile phone to the mobile phone by a user, and starts a bluetooth search to obtain a plurality of bluetooth devices; determining at least one vehicle-mounted Bluetooth from the plurality of Bluetooth devices according to the primary device type and/or the secondary device type of each Bluetooth device in the plurality of Bluetooth devices; in the case that the at least one vehicle-mounted Bluetooth is a plurality of vehicle-mounted Bluetooth, the target vehicle-mounted Bluetooth is determined from the at least one vehicle-mounted Bluetooth according to the signal intensity and/or the direction angle of each vehicle-mounted Bluetooth.

In the embodiment of the application, the travel service of the mobile phone searches at least one bluetooth device with visible periphery through the first bluetooth module, obtains bluetooth information of each bluetooth device in the at least one bluetooth device, wherein the bluetooth information can include information such as a bluetooth name, an MAC address, a device attribute and the like, and the device attribute can indicate a main device type of the bluetooth device, for example, the main device type is an audio device.

In some cases, no other bluetooth device is searched for outside and inside the vehicle in which the user is located, except for the own vehicle's onboard bluetooth. In this case, the number of the at least one bluetooth device is one, and the travel service determines that the bluetooth device is the target vehicle bluetooth after determining that the bluetooth device is the audio class device according to the main device type.

In the case where the at least one bluetooth device is plural, for each bluetooth device of the plurality of bluetooth devices, the travel service first determines whether each bluetooth device is an audio class device according to the primary device type. For the Bluetooth device determined to be the Bluetooth audio device, the travel service acquires the secondary device type of the Bluetooth audio device through the existing framework interface of the first Bluetooth module, and further determines whether each Bluetooth audio device is a vehicle-mounted audio device (or can be called vehicle Bluetooth) according to the secondary device type, so that at least one vehicle-mounted audio device is determined.

In addition, the travel service can directly acquire the secondary device type of each Bluetooth device, and determine at least one vehicle-mounted audio device from the plurality of Bluetooth devices based on the secondary device type.

Through the steps, the travel service can exclude the Bluetooth earphone and the Bluetooth watch of all passengers in the vehicle. In one possible implementation, after determining the at least one car audio class device, in order to distinguish the car audio class device from other non-car audio class devices, the travel service may increase the weight of each car audio class device in the at least one car audio class device by a first value, for example, the first value is 40%. In this way, the weight of the in-vehicle audio class device is higher than that of the other non-in-vehicle audio class devices, and the in-vehicle audio class device with the higher weight can be displayed in the queue of available in-vehicle bluetooth (also may be referred to as in-vehicle bluetooth list) as shown in fig. 4, while the other non-in-vehicle audio class devices are displayed in the queue of the other devices as shown in fig. 4.

Fig. 4 is an interface schematic diagram of a vehicle audio device according to an embodiment of the present application. As shown in fig. 4, the finally screened car audio devices are in the available car bluetooth queues of the mobile phone, for example, the car audio device a, the car audio device B and the car audio device C in fig. 4, and the ranks of the car audio devices in the available car bluetooth queues indicate the corresponding connection priorities, where the connection priority of the car audio device a is the highest, the connection priority of the car audio device B is the next highest, and the connection priority of the car audio device C is the next lowest. While other bluetooth devices are in the queue of other devices, such as audio class device D in fig. 4, which may be a bluetooth headset or a bluetooth watch, etc.

After determining the at least one car audio class device, the trip service determines that the car audio class device is the target car Bluetooth, if possible, the number of the at least one car audio class device is one. In another possible case, the number of the at least one car audio class device is a plurality, and the travel service determines the target car Bluetooth from the plurality of car audio class devices according to the signal intensity and/or the direction angle of each car audio class device.

It is assumed below that the car audio class device C in fig. 4 is the target car bluetooth to which the user desires to connect, and the car audio class device a is the car bluetooth located on the left of the vehicle that the user is driving, and the car audio class device B is the car bluetooth located on the right of the vehicle that the user is driving. At this time, the connection priority of the car audio class device C is not yet highest. Further, the travel service of the mobile phone adjusts the connection priority of each vehicle-mounted audio equipment in the queue of available vehicle-mounted Bluetooth through the signal intensity.

And the travel service of the mobile phone obtains the signal intensity and the stability time of the vehicle-mounted audio equipment through the existing frame interface of the first Bluetooth module according to the searched Bluetooth name of the vehicle-mounted audio equipment. For example, the trip service may screen out the first 5 car audio devices according to the principle that the signal fluctuation is not more than 50% and lasts for 3 seconds within the range of 1 meter, increase the weight of the car audio device with the strongest bluetooth signal by the second numerical value, and sequentially decrease the weight increment of the car audio device with the inferior signal strength by the third numerical value.

In one example, the second value is 40%, the third value is 8%, that is, the travel service increases the weight of the car audio device with the strongest signal by 40%, increases the weight of the car audio device with the second signal intensity by 32%, increases the weight of the car audio device with the third signal intensity by 24%, and so on, to increase the corresponding weight for the car audio device with the signal intensity of 5.

Through the steps, the travel service can exclude vehicle-mounted audio equipment far away, and increase the weight of the vehicle-mounted audio equipment (high and stable in signal strength) nearest to the driver, so that the ordering of the vehicle-mounted audio equipment in the queue of available vehicle-mounted Bluetooth is improved.

Fig. 5 is a schematic diagram of another interface for displaying a vehicle audio device according to an embodiment of the present application. As shown in fig. 5, the ranking of the car audio class device C to which the user desires to connect is raised in the queue of available car bluetooth, while the ranking of the car audio class device B located on the right of the vehicle that the user drives is lowered.

In practice, the signal strength of the target bluetooth in the vehicle may not be the strongest, resulting in a situation where the target bluetooth in the vehicle is not ranked first in the queue of available bluetooth in the vehicle, because of the irregular/too strong power of the bluetooth in the vehicle of the other vehicle. For this situation, the travel service of the mobile phone can further utilize the direction angle of the bluetooth dual antenna for further processing.

The travel service of the mobile phone inquires of Bluetooth equipment in a preset angle range in front of the right of the driving position by utilizing the double antenna of the first Bluetooth module and the capability of measuring the direction of the departure angle (angle of departure, AOD) or the arrival angle (AOA) of the Bluetooth protocol.

Under the condition that the number of the vehicle-mounted Bluetooth in the preset angle range is one, the travel service determines that the vehicle-mounted Bluetooth is a target vehicle-mounted Bluetooth; and under the condition that the number of the vehicle-mounted Bluetooth in the preset angle range is a plurality of vehicle-mounted Bluetooth, the travel service determines that the vehicle-mounted Bluetooth with the strongest signal is the target vehicle-mounted Bluetooth.

Through the steps, the travel service determines the vehicle-mounted Bluetooth in a preset angle range right in front of the user by combining the signal intensity and the direction angle of each vehicle-mounted audio equipment, and adds a fourth value to the weight of the vehicle-mounted Bluetooth in the preset angle range, wherein the preset angle range is 0-70 degrees, and the fourth value is 20%. In this way, the vehicle-mounted audio equipment with the highest weight can be determined to be the target vehicle-mounted Bluetooth and displayed at the first position of the queue of available vehicle-mounted Bluetooth, so that the vehicle-mounted audio equipment near the vehicle driven by the user is eliminated.

Fig. 6 is a schematic diagram of an interface for displaying a vehicle audio device according to an embodiment of the present application. As shown in fig. 6, the car audio class device C is the target car bluetooth of the user, and is already arranged at the head of the queue of available car bluetooth.

The above-described case where the power of the on-board bluetooth of the other vehicle is not normalized/too strong results in the signal strength of the target on-board bluetooth not being strongest is a small probability event. Considering the general situation, in another implementation manner, the travel service may further determine a vehicle-mounted audio device with the strongest signal in the at least one vehicle-mounted audio device as the target vehicle-mounted bluetooth.

In still another implementation manner, the travel service may further determine a vehicle-mounted audio device with a direction angle within a preset angle range in the at least one vehicle-mounted audio device as the target vehicle-mounted bluetooth.

When the target vehicle-mounted Bluetooth is determined, and after the target vehicle-mounted Bluetooth is displayed at the first position of the queue of available vehicle-mounted Bluetooth, the travel service of the mobile phone reminds the user whether to connect to the vehicle-mounted Bluetooth displayed at the first position of the available vehicle-mounted Bluetooth through the voice assistant of the mobile phone. Illustratively, the voice assistant prompts the user "please confirm if the car of XXX is connected", which the user can confirm manually or by voice. After the user confirms, the travel service sends a connection instruction to the first Bluetooth module, and the connection instruction carries the MAC address of the target vehicle Bluetooth.

After receiving the connection instruction, the first Bluetooth module is connected with the target vehicle-mounted Bluetooth based on the MAC address of the target vehicle-mounted Bluetooth, and in the embodiment of the application, the first Bluetooth module is the second Bluetooth module connected with the vehicle. After confirming the connection, the second Bluetooth module sends a message of successful connection to the second vehicle interconnection protocol, and returns a message of successful connection to the first Bluetooth module, so that a physical communication channel of a bottom layer is established between the mobile phone and the vehicle. After receiving the message of successful connection, the first Bluetooth module informs the travel service of successful connection, and the travel service sends an instruction for starting private data channel connection to the first vehicle-mounted interconnection protocol, and carries Bluetooth information of a mobile phone and Bluetooth information of a vehicle-mounted device, wherein the Bluetooth information comprises a Bluetooth name and an MAC address.

After the bluetooth information of the mobile phone and the bluetooth information of the vehicle are acquired, the first vehicle interconnection protocol and the second vehicle interconnection protocol can establish a private service communication channel based on bluetooth serial port protocol (serial port profile, SPP) service according to the bluetooth protocol specification, and data transmission in a private format is performed.

After the Bluetooth connection is completed, the mobile phone travel service is used as a policy center, wi-Fi P2P connection can be tried first, and Wi-Fi hot spot connection is tried again under the condition that the Wi-Fi P2P connection fails.

Optionally, after the bluetooth connection is completed, the travel service may query an input-output (IO) capability of the connected target vehicle bluetooth through the first bluetooth module, check whether the target vehicle bluetooth has a screen display and input capability, and if not, may apply a subsequent screen-throwing service and a reverse control service of the mobile phone, and the mobile phone may prompt the user that the target vehicle does not have the screen display and input capability at bluetooth.

In one possible implementation, the trip service module reads a device type (COD) field of the target bluetooth on board through an interface of the first bluetooth module, obtains a corresponding mask (mask) position, and determines whether the device type (COD) field has both an input capability (keyboard) and a screen display (number output) capability.

Second phase, wi-Fi P2P connection.

The travel service of the mobile phone sends an instruction for starting the Wi-Fi P2P connection mode to the first vehicle interconnection protocol. The first vehicle interconnection protocol waits for and receives Wi-Fi P2P connection information (namely GO information of the vehicle) sent by the second vehicle interconnection protocol through the private service communication channel established in the first stage, wherein the GO information comprises the name, the MAC address and the password of Wi-Fi P2P of the vehicle. After the first vehicle interconnection protocol receives the GO information sent by the second vehicle interconnection protocol, the travel service vehicle is informed of supporting the Wi-Fi P2P connection mode, and the travel service considers that the Wi-Fi P2P capability detection of the vehicle is successful.

If the vehicle does not support Wi-Fi P2P connection due to the chip specification of Wi-Fi, the antenna cost and the like, the first vehicle interconnection protocol does not receive GO information sent by the second vehicle interconnection protocol.

In a possible case, the second vehicle interconnection protocol sends a message that the vehicle does not support Wi-Fi P2P connection to the first vehicle interconnection protocol, and after receiving the message that the vehicle does not support Wi-Fi P2P connection, the first vehicle interconnection protocol notifies a travel service vehicle of the mobile phone that the vehicle does not support Wi-Fi P2P connection, and then the travel service determines that the vehicle does not support Wi-Fi P2P connection mode, and enters a third stage.

In another possible case, if the travel service does not receive the message indicating whether the vehicle machine supports Wi-Fi P2P connection for the first preset duration, the travel service considers that the vehicle machine does not support Wi-Fi P2P connection mode, and enters the third stage. The first preset duration is illustratively 5 seconds, but embodiments of the present application are not limited thereto.

Under the condition that the vehicle supports a Wi-Fi P2P connection mode, the first vehicle interconnection protocol sends a Wi-Fi P2P connection instruction to the first Wi-Fi P2P module, carries GO information, and informs the first Wi-Fi P2P module to be used as a role of GC to access the second Wi-Fi P2P module. After the first Wi-Fi P2P module receives the Wi-Fi P2P connection instruction, wi-Fi P2P connection is established with the second Wi-Fi P2P module based on the GO information.

After receiving the Wi-Fi P2P connection instruction, the second Wi-Fi P2P module may establish a connection with the first Wi-Fi P2P module successfully, or may also establish a connection failure. The second Wi-Fi P2P module sends Wi-Fi P2P connection results to the first Wi-Fi P2P module according to whether connection establishment is successful or not, and the Wi-Fi P2P connection results comprise connection success and connection failure. And after receiving the Wi-Fi P2P connection result, the first Wi-Fi P2P module returns the Wi-Fi P2P connection result to the first vehicle interconnection protocol.

Under the condition that the Wi-Fi P2P of the first Wi-Fi P2P module and the Wi-Fi P2P of the second Wi-Fi P2P module are successfully connected, the Wi-Fi P2P module is used for successfully establishing a data channel between a first vehicle interconnection protocol and a second vehicle interconnection protocol, and can be used for subsequently transmitting service data such as screen throwing data and audio data.

Under the condition that the Wi-Fi P2P connection of the first Wi-Fi P2P module and the second Wi-Fi P2P module fails, the travel service starts a Wi-Fi hot spot automatic connection strategy and enters a third stage.

And in the third stage, wi-Fi hot spot connection.

After the travel service of the mobile phone determines that the mobile phone does not support the Wi-Fi P2P connection mode, the travel service sends an instruction for starting the Wi-Fi hot spot to the Wi-Fi hot spot module of the mobile phone. After receiving the instruction for starting the Wi-Fi hot spot, the Wi-Fi hot spot module starts the Wi-Fi hot spot, and returns a successful message for starting the Wi-Fi hot spot to the travel service, wherein the message carries the hot spot name and the password. The mobile phone travel service displays the name and the password of the hot spot to the user in a user interface and prompts the user to connect the hot spot from a Wi-Fi module of the car machine. Compared with the prior art that the user is required to find the connection mode in the multi-layer directory of the mobile phone, the mobile phone can automatically start Wi-Fi hotspots and prompt the user, and the user is not required to find the hotspot names and passwords, so that the mode is more convenient and easy to operate, and the time for finding by the user is reduced.

In a Wi-Fi hot spot connection mode, a Wi-Fi hot spot module of a mobile phone is used as an AP, a Wi-Fi module of a vehicle is used as an STA, and the Wi-Fi module of the vehicle as the STA is called a Wi-Fi STA module in the embodiment of the application.

Based on the prompt of the mobile phone, a user can be connected with a Wi-Fi hot spot module of the mobile phone through a Wi-Fi STA module of the vehicle. And the Wi-Fi hot spot module returns a Wi-Fi hot spot connection result to the first vehicle interconnection protocol, wherein the connection result comprises connection success or connection failure. The Wi-Fi hotspot module sends Wi-Fi hotspot connection results to the travel service.

And under the condition that the Wi-Fi hot spot connection result is that the connection is successful, if the travel service receives a message of successful Wi-Fi hot spot connection within a second preset time period, determining that the Wi-Fi hot spot connection is successful. If the travel service does not receive the message of successful connection within the second preset time period or the travel service receives the message of failure connection, the travel service determines that Wi-Fi hot spot connection fails.

And under the condition that the Wi-Fi hot spot connection is successful, sending an instruction for starting the service layer service to the first vehicle interconnection protocol, and starting the service layer service by the first vehicle interconnection protocol based on the instruction. After confirming the connection, the Wi-Fi STA module sends a message of successful Wi-Fi hot spot connection to the second vehicle interconnection protocol. The second handset interconnection protocol also initiates business layer services after receiving the Wi-Fi hotspot connection success message.

Therefore, after the Wi-Fi hotspot module is successfully connected with the Wi-Fi hotspot of the Wi-Fi STA module, the Wi-Fi hotspot module is successfully established for a data channel between the first vehicle interconnection protocol and the second vehicle interconnection protocol, and can be used for subsequently transmitting service data such as screen throwing data, audio data and the like.

Under the condition that the Wi-Fi hot spot connection is determined to be failed, the travel service prompts the user to skip to a guiding interface of the wired connection without supporting the wireless connection.

In the embodiment of the application, the mobile phone can finish the accurate vehicle Bluetooth identification frame and algorithm through the cooperation of hardware, a system, middleware, application and a vehicle-to-machine interconnection protocol, and manufacturers of vehicle-to-machine interconnection application and automobile manufacturers do not need to make great changes and adaptations, thereby being convenient for maintenance and upgrading.

Aiming at two wireless connection modes supporting a certain type of vehicle-machine interconnection protocol, the mobile phone can dynamically traverse two different wireless connection modes, a Wi-Fi P2P connection mode which is more automatic and saves power consumption is preferentially selected, and a Wi-Fi hot spot connection mode is selected under the condition that the connection mode fails.

In addition, the same mobile phone has consistent operation steps for the car machines supporting different types of wireless connection modes and the car machines not supporting the wireless connection modes and only supporting wired connection, thereby being beneficial to keeping the consistency of the operation habits of users.

In the third stage described above, the user needs to connect the Wi-Fi hotspot of the mobile phone from the Wi-Fi module of the vehicle manually at the vehicle side. In order to realize the complete automatic connection of the mobile phone, if the vehicle terminal can open the authority of Wi-Fi STA module connection, the vehicle terminal can automatically connect with the Wi-Fi hot spot of the mobile phone without manual connection of a user.

Under the condition that the vehicle side opens the authority of Wi-Fi STA module connection, the mobile phone can also concurrently attempt Wi-Fi hot spot connection and Wi-Fi P2P connection, and the method is particularly shown in fig. 7.

Fig. 7 is a schematic flow chart of another method for connecting a vehicle machine according to an embodiment of the present application. The mobile phone comprises a first vehicle interconnection protocol, a first Wi-Fi P2P module, a first Bluetooth module, a Wi-Fi hot spot module and travel service. The vehicle machine comprises a second Bluetooth module, a second vehicle machine interconnection protocol, a second Wi-Fi P2P module and a Wi-Fi STA module.

The method for connecting the vehicle machine provided by the embodiment of the application can be divided into two stages, wherein the first stage is Bluetooth connection, and the second stage is parallel connection of Wi-Fi P2P connection and Wi-Fi hot spot connection. The stages are described separately below in connection with fig. 4.

The first stage is similar to the first stage described in fig. 6, and will not be described here.

And in the second stage, the Wi-Fi P2P connection and the Wi-Fi hot spot connection are detected in parallel.

In the parallel connection phase, the Wi-Fi P2P connection procedure is similar to the second phase described in fig. 6, and will not be repeated here. In the Wi-Fi hotspot connection process, the travel service sends a Wi-Fi hotspot starting instruction to a Wi-Fi hotspot module of the mobile phone. After receiving the instruction for starting the Wi-Fi hot spot, the Wi-Fi hot spot module starts the Wi-Fi hot spot, and returns a successful message for starting the Wi-Fi hot spot to the travel service, wherein the message carries the hot spot name and the password. And the trip service sends a hot spot access message to the first vehicle interconnection protocol based on the message, wherein the hot spot access message carries a hot spot name and a password. After the first vehicle interconnection protocol receives the hot spot access message, the first vehicle interconnection protocol transmits the hot spot access message through a private service communication channel established by the first vehicle interconnection protocol and the second vehicle interconnection protocol in the first stage, and the hot spot access message carries a hot spot name and a password. After receiving the hotspot access message, the second vehicle interconnection protocol sends an instruction for connecting the Wi-Fi hotspot to the Wi-Fi STA module, wherein the instruction carries a hotspot name and a password. The Wi-Fi STA module can initiate Wi-Fi hotspot connection after receiving the instruction for connecting the Wi-Fi hotspot, and is connected with the Wi-Fi hotspot module of the mobile phone.

The travel service of the mobile phone can detect Wi-Fi P2P connection and Wi-Fi hot spot connection in parallel, and if only one of the Wi-Fi P2P connection and the Wi-Fi hot spot connection is successful, the travel service selects a successful connection mode. Or the trip service determines which connection is successful, namely which connection mode is selected, and further indicates that the module which is not connected successfully stops connecting.

In the embodiment of the application, the wireless connection mode of the mobile phone is more automatic, and a user does not need to manually connect with a Wi-Fi hot spot of the mobile phone under the condition that the vehicle opens Wi-Fi STA connection authority, so that the user operation is simplified.

If the Wi-Fi P2P connection and the Wi-Fi hotspot connection in fig. 6 or fig. 7 are failed, after receiving the connection failure message sent by the Wi-Fi hotspot module, the travel service prompts the vehicle to not support wireless connection at the user interface of the mobile phone, tries to intelligently guide the user to try other connection modes such as USB connection, and jumps to the guiding interface of wired connection. Therefore, the user can find the guiding interface of the wired connection without searching the multi-layer catalogue, and the operation of the user is reduced. And the mobile phone can guide the user to perform wired connection, so that the learning cost of the user for learning the wired connection is reduced, and the usability and the success of interconnection of the mobile phone and the vehicle are improved.

Fig. 8 is a schematic diagram of an interface of a wired connection according to an embodiment of the present application.

In one possible implementation, referring to the interface a in fig. 8, after the mobile phone guides the user to open the vehicle interconnection application at the vehicle end in the user interface, the mobile phone is connected by using the USB data line to complete the connection. But connection compatibility problems may occur during a wired connection resulting in connection failure, the user may be prompted in the a interface to attempt to use the enhanced connection mode in the event of a connection failure. When the user selects the button of "enhanced connection mode", the process jumps to the C interface as in fig. 8.

In another possible implementation, in case of a failure of the wired connection, the mobile phone automatically pops up the B interface as in fig. 8, prompting the user to use the enhanced connection mode. When the user selects the "go" button, jump to the C interface as in fig. 8. Besides popup window prompt, the mobile phone can also prompt the user to start the enhanced connection mode by voice under the condition of the failure of the wired connection, and after receiving the confirmation message replied by the user, the mobile phone can jump to the C interface in fig. 8. The embodiment of the application does not limit the mode of prompting the user.

After the handset displays the C interface in fig. 8, the user may click on the "open enhanced connection" button to initiate the enhanced connection.

In the embodiment of the application, when the wireless connection mode fails, the mobile phone can automatically conduct a guiding interface of wired connection, and further can conduct targeted guiding on the enhanced connection mode.
