In step S212, a plurality of actual radio frequency arrival angles of the mobile terminal are obtained by the BLE node.

The actual radio frequency reaching angle is as follows: for example, assuming that the current position of the mobile terminal is x, bluetooth signals can be broadcast to other BLE nodes and the mobile terminal through the BLE nodes, and the actual radio frequency reaching angle of the mobile terminal is obtained through calculation of the antenna array of the BLE nodes.

and recording the first radio frequency reaching angle, the second radio frequency reaching angle, the third radio frequency reaching angle, the fourth radio frequency reaching angle, the fifth radio frequency reaching angle and the sixth radio frequency reaching angle as a plurality of actual radio frequency reaching angles of the mobile terminal.

In step S213, a plurality of variances between a plurality of actual radio frequency arrival angles and a plurality of standard radio frequency arrival angles of different seats are respectively obtained.

In the above steps, each BLE node calculates two actual radio frequency reaching angles, and calculates a variance between the actual radio frequency reaching angle calculated by each BLE node and the standard radio frequency reaching angle calculated by the BLE node, wherein the variances are multiple. Calculating the variance of the actual radio frequency reaching angle and the standard radio frequency reaching angle corresponding to the seat a, calculating the variance of the actual radio frequency reaching angle and the standard radio frequency reaching angle corresponding to the seat b, calculating the variance of the actual radio frequency reaching angle and the standard radio frequency reaching angle corresponding to the seat c, calculating the variance of the actual radio frequency reaching angle and the standard radio frequency reaching angle corresponding to the seat d, and calculating the variance of the actual radio frequency reaching angle and the standard radio frequency reaching angle corresponding to the seat e; the following shows the way in which the variance of the actual radio frequency arrival angle with the standard radio frequency arrival angle corresponding to seat a is calculated:

illustratively, a first variance between an actual radio frequency arrival angle obtained by the first node and a plurality of standard radio frequency arrival angles of different seats obtained by the first node is calculated; the actual radio frequency reaching angles obtained by the first node are (2, x) and (3, x), the standard radio frequency reaching angle corresponding to the seat a has (2, a) and (3, a) calculated by the first node, and a first variance between (2, x), (3, x) and (2, a), (3, a) is calculated;

calculating a second variance between the actual radio frequency arrival angle obtained by the second node and a plurality of standard radio frequency arrival angles of different seats obtained by the second node; the actual radio frequency reaching angles obtained by the second node are (1, x) and (3, x), the standard radio frequency reaching angle corresponding to the seat a has (1, a) and (3, a) calculated by the second node, and a second variance between (1, x), (3, x) and (1, a), (3, a) is calculated;

and in the case that the first variance, the second variance and the third variance are all smaller than a specified threshold value, indicating that the mobile terminal is close to the position of the seat a or is at the position of the seat a.

In step S214, in the case where there is one variance smaller than the specified threshold among the plurality of variances, it is determined that the mobile terminal is in the vehicle.

And under the condition that the first variance, the second variance and the third variance are all smaller than a specified threshold value, determining that one variance smaller than the specified threshold value exists in a plurality of variances corresponding to different seats, and determining that the mobile terminal is in the vehicle. The smaller the variance, the closer the mobile terminal is to the vehicle seat. The threshold is a reasonable value, and can be obtained based on human experience or other feasible methods.

In step S22, in the case where the mobile terminal is inside the vehicle, the start message is sent to the central gateway of the vehicle through the master node in the BLE node.

Under the condition that the mobile terminal is in the vehicle, sending a starting message to a central gateway of the vehicle through a main node in the BLE node; the start message is used for instructing a central gateway of the vehicle to start a WiFi network facing the mobile terminal, so that the mobile terminal is connected to the WiFi network of the vehicle, and the master node may be any one of the BLE nodes.

In step S23, the central gateway is controlled to start the SOA service for the mobile terminal through the WiFi network of the vehicle.

Controlling a central gateway to start SOA service facing a mobile terminal through a WiFi network of a vehicle; the SOA service facing the mobile terminal is a part of the full-function SOA service of the whole vehicle, the SOA service facing the mobile terminal is defined in a first domain, and the full-function SOA service of the whole vehicle is defined in a second domain.

Under the condition that the mobile terminal is connected with a WiFi network of a vehicle, the mobile terminal is controlled to automatically register SOA service facing the mobile terminal through the WiFi network, after the registration, the mobile terminal can call the SOA service defined in a first domain to control functions of parts in the vehicle, such as control of lifting of a vehicle window, air conditioner temperature in the vehicle, air volume, a skylight, a seat service interface and the like.

It should be noted that, the full-function SOA service of the entire vehicle is called, the vehicle needs to be registered and bound by using the mobile terminal, and the certificate distributed to the vehicle by the PKI server is downloaded. And the application on the mobile terminal performs bidirectional authentication with the certificate of the SOA service in the vehicle through the certificate, and after the bidirectional authentication is passed, the mobile terminal can register the full-function SOA service of the whole vehicle through the communication middleware and call the full-function SOA service of the whole vehicle so as to realize the service requirement of calling the full-function SOA service of the whole vehicle. Full-vehicle full-function SOA services are typically driver-oriented, while mobile terminal-oriented SOA services are typically passenger-oriented. The SOA service for the passengers can be automatically registered after the mobile terminal of the passenger is connected with the WiFi network in the vehicle, so that the passenger can call partial SOA service of the vehicle through the mobile terminal, and partial functions in the vehicle, such as control of lifting of a vehicle window, air conditioning temperature in the vehicle, air volume, skylight, seat service interfaces and the like, are controlled, complicated bidirectional authentication with the vehicle is not needed, partial functions of the vehicle are called, and riding experience of the user is improved.

Note that, in the case where it is detected that the mobile terminal moves from inside the vehicle to outside the vehicle, the SOA service for the mobile terminal is turned off by the BLE node. The BLE node can position the position of the mobile terminal in real time, and under the condition that the mobile terminal is outside the vehicle, the SOA service facing the mobile terminal is closed through the BLE node.

In summary, the service invocation method provided by the present disclosure includes that when a low-power bluetooth BLE node of a vehicle detects a bluetooth signal of a mobile terminal, the BLE node locates the position of the mobile terminal, when the mobile terminal is in the vehicle, an SOA service facing the mobile terminal is started through the BLE node, and when the mobile terminal is outside the vehicle, the SOA service facing the mobile terminal is closed through the BLE node; the SOA service facing the mobile terminal is one part of the full-function SOA service of the whole vehicle, the partial SOA service facing the mobile terminal is started through the BLE node, the mobile terminal does not need to perform complicated bidirectional authentication with the vehicle, a user can call partial SOA service of the vehicle through the mobile terminal, partial functions in the vehicle are controlled, and riding experience of the user is improved.

Although fig. 5 functionally illustrates a second processor, a second memory, and other elements of the computer in the same block, one of ordinary skill in the art will appreciate that the second processor, computer, or second memory may actually comprise multiple second processors, computers, or second memories that may or may not be stored within the same physical housing. For example, the second memory may be a hard disk drive or other storage medium located in a different enclosure than the computer. Thus, references to a second processor or computer will be understood to include references to a set of second processors or computers or second memories which may or may not operate in parallel. Rather than using a single second processor to perform the steps described herein, some components, such as the steering and deceleration components, may each have their own second processor that performs only computations related to the component-specific functions.

In the embodiment of the present disclosure, the second processor 651 may execute the service invocation method described above.

In various aspects described herein, the second processor 651 can be located remotely from the vehicle and in wireless communication with the vehicle. In other aspects, some of the processes described herein are executed on a second processor disposed within the vehicle and others are executed by a remote second processor, including taking the steps necessary to execute a single maneuver.

Such information may be used by the vehicle 600 and the computing platform 650 during operation of the vehicle 600 in autonomous, semi-autonomous, and/or manual modes.

The computing platform 650 may control functions of the vehicle 600 based on inputs received from various subsystems (e.g., the drive system 640, the perception system 620, and the decision control system 630). For example, computing platform 650 may utilize input from decision control system 630 in order to control steering system 633 to avoid obstacles detected by perception system 620. In some embodiments, the computing platform 650 is operable to provide control over many aspects of the vehicle 600 and its subsystems.

Optionally, one or more of these components described above may be mounted or associated separately from the vehicle 600. For example, the second memory 652 may exist partially or completely separate from the vehicle 600. The above components may be communicatively coupled together in a wired and/or wireless manner.

Optionally, the above components are only an example, in an actual application, components in the above modules may be added or deleted according to an actual need, and fig. 5 should not be construed as limiting the embodiment of the present disclosure.

An autonomous automobile traveling on a roadway, such as vehicle 600 above, may identify objects within its surrounding environment to determine an adjustment to the current speed. The object may be another vehicle, a traffic control device, or another type of object. In some examples, each identified object may be considered independently, and based on the respective characteristics of the object, such as its current speed, acceleration, separation from the vehicle, etc., may be used to determine the speed at which the autonomous vehicle is to be adjusted.

Optionally, the vehicle 600 or a sensory and computing device associated with the vehicle 600 (e.g., computing system 631, computing platform 650) may predict behavior of the identified object based on characteristics of the identified object and the state of the surrounding environment (e.g., traffic, rain, ice on the road, etc.). Optionally, each of the identified objects is dependent on the behavior of each other, so all of the identified objects can also be considered together to predict the behavior of a single identified object. The vehicle 600 is able to adjust its speed based on the predicted behavior of the identified object. In other words, the autonomous vehicle is able to determine what steady state the vehicle will need to adjust to (e.g., accelerate, decelerate, or stop) based on the predicted behavior of the object. In this process, other factors may also be considered to determine the speed of the vehicle 600, such as the lateral position of the vehicle 600 in the road being traveled, the curvature of the road, the proximity of static and dynamic objects, and so forth.

In addition to providing instructions to adjust the speed of the autonomous vehicle, the computing device may also provide instructions to modify the steering angle of the vehicle 600 to cause the autonomous vehicle to follow a given trajectory and/or maintain a safe lateral and longitudinal distance from objects in the vicinity of the autonomous vehicle (e.g., vehicles in adjacent lanes on the road).

The vehicle 600 may be any type of vehicle, such as a car, a truck, a motorcycle, a bus, a boat, an airplane, a helicopter, a recreational vehicle, a train, etc., and the disclosed embodiment is not particularly limited.

In another exemplary embodiment, a computer program product is also provided, which comprises a computer program executable by a programmable apparatus, the computer program having code portions for performing the above-mentioned service invocation method when executed by the programmable apparatus.
