Background
With the rapid development of communication technology, communication interaction between a mobile phone and an automobile becomes more and more common, and the mobile phone can provide diversified application services for the automobile. Under different use states, the automobile needs the mobile phone to execute different application functions in a matching way. For example, when a user gets on a car and starts the car, the user usually uses a mobile phone to perform destination navigation; when a user gets off the automobile and turns off, the user often takes out the mobile phone to take a picture and record the parking position. Therefore, if the mobile phone can automatically determine the use state of the vehicle, the corresponding application service can be better provided for the automobile.
In the prior art, a solution exists in which a motion speed of a vehicle is determined by a Global Positioning System (GPS) or a motion sensor, so as to determine a use state of the vehicle. However, the misjudgment rate of the scheme is very high, and for example, when the automobile is temporarily stopped (for example, waiting for a red light or traffic jam), the misjudgment can be made that the user gets off the automobile.

Specifically, the input unit 1130 may include a touch screen 1131 and other input devices 1132. The touch screen 1131 may collect touch operations performed by a user on or near the touch screen 1131 (for example, operations performed by the user on or near the touch screen 1131 by using any suitable object or accessory such as a finger or a stylus pen), and drive the corresponding connection device according to a preset program. Specifically, the touch operation may include one or more of the following operation modes: such as pressure operation, touch operation (e.g., slide operation, drag operation), click operation, multi-touch operation, button input, long press input, etc. The input unit 1130 may include other input devices 1132 in addition to the touch screen 1131.

Further, the touch screen 1131 can be overlaid on the display screen 1141, and when the touch screen 1131 detects a touch operation thereon or nearby, the touch operation is transmitted to the processor 1180 to determine the type of the touch event, and then the processor 1180 provides a corresponding visual output on the display screen 1141 according to the type of the touch event. Although in FIG. 1, touch screen 1131 and display 1141 are shown as two separate components to implement input and output functions of terminal 100, in some embodiments, touch screen 1131 and display 1141 can be integrated to implement input and output functions of terminal 100.

The technical scheme provided by the embodiment of the invention is applied to the scene after the terminal and the vehicle establish short-distance communication connection as shown in fig. 1, and the following are taken as examples:
the user carries the terminal to enter the vehicle, and the vehicle is started to be electrified. The terminal establishes short-distance communication connection with the vehicle, wherein the terminal and the vehicle are both provided with short-distance communication modules and have short-distance communication capacity. The connection mode can be that the user establishes the connection manually or the terminal establishes the connection with the vehicle automatically. Because the short-range communication module of the vehicle is powered on to work when the vehicle is started, the terminal and the vehicle can keep a connection state of short-range communication connection. When the vehicle is shut down and stopped, the short-distance communication module of the vehicle is powered off, the short-distance communication connection between the terminal and the vehicle is disconnected, so that the terminal can determine the using state of the vehicle according to the connection state of the short-distance communication connection between the terminal and the vehicle, if the terminal is in the connection state, the vehicle is determined to be in the starting state, if the terminal is disconnected, the user is determined to be parked and shut down, and the short-distance communication module of the vehicle is disconnected from the terminal due to the power off.
In practical application, the terminal can be a mobile phone, a tablet computer, an intelligent wearable device and other devices with a short-distance communication function.
In the embodiment of the present invention, the term "short-range communication connection" refers to a communication connection technique in which both communication transceivers whose transmission distance is limited to a short range continuously transmit information by radio waves. The short-range Communication connection may be one or more of Bluetooth (Bluetooth) connection, ZigBee connection, infrared data Association (IrDA) connection, Wireless Fidelity (WiFi) connection, Ultra Wideband (UWB) connection, Near Field Communication (NFC) connection, and the like.
In the embodiment of the invention, when the vehicle is referred to, the vehicle integrates the short-range communication module and has short-range communication capability. Specifically, the short-range communication module of the vehicle may be a bluetooth module, a WIFI module, an infrared module, an ultra-wideband module, an NFC module, or the like. The short-range communication module can be a hardware module (such as a Bluetooth chip) or a software module. Vehicles include all types of vehicles having a powertrain capable of powering the short-range communication module, such as electric vehicles, gasoline vehicles, hybrid vehicles, and the like.
When the "connection state of the short-distance communication connection" is mentioned in the embodiment of the present invention, two connection states of connected and disconnected are mainly included. The "connected" state means a state in which both the communication transmitter and the communication receiver have successfully established a communication channel and data or signal transmission is possible. The "disconnected" state means a state in which the communication transceiver and the communication transmitter have not successfully established a communication channel and cannot transmit data or signals. Wherein, the connection between the communication transceiver and the communication transceiver is also in a disconnected state.
When the "usage state of the vehicle" is mentioned in the embodiment of the present invention, the startup state and the shutdown state are mainly included. "activated state" refers to a state in which the circuitry of the vehicle has been energized. After the vehicle is powered on, the short-range communication module on the vehicle can establish short-range communication connection with the terminal, so that the starting state of the vehicle refers to the state of the short-range communication module in the vehicle after being powered on. Since different short-range communication modules may be powered up at different times, for example, the NFC module of the vehicle is powered up when the vehicle is powered on and the engine is not yet ignited (e.g., the ACC state of the automobile), and the bluetooth module of the vehicle needs to be powered up after the engine of the vehicle is ignited, the "start-up state" of the vehicle may be different for different short-range communication modules of the vehicle. The vehicle is in the "on state" both during driving after ignition and when the engine is turned off without stopping temporarily in the middle of the vehicle. The "key-off state" refers to a state in which the vehicle is powered off after the vehicle is turned off.
When referring to the "first preset function" in the embodiment of the present invention, it means that the application function to be executed is preset when the terminal determines that the use state of the vehicle is the activation state. The "first preset function" may be a function of a terminal system application, or may be a function of a third party application installed on the terminal, and the type of the application is not particularly limited herein. The "first preset function" may be set or modified by the user, or may be preset by the terminal, independent of the user, and the preset manner is not limited. The "first preset function" may be to invoke and open a certain application on the terminal, or may be a specific function of a certain application, and the function type is not limited. For example, the "first preset function" may be to start a navigation application installed on the terminal, display a main interface of the navigation application, or automatically input a destination to perform a navigation service; for another example, the "first preset function" may be to start a music player on the terminal and display a main interface of the music player, or to directly play a music file after the music player is started.
The "second preset function" mentioned in the embodiment of the present invention refers to an application function that is preset to be executed when the terminal determines that the use state of the vehicle is the key-off state. The meaning of the "second preset function" is similar to that of the "first preset function", and the application type, the preset mode and the function type are not limited.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a schematic flow chart of a vehicle use state determination method according to an embodiment of the present invention. As shown in fig. 2, the execution subject of the vehicle use state determination method of the present embodiment is a terminal, and the method includes:
s101, starting the vehicle, and powering on a short-distance communication module of the vehicle.
S103, the terminal establishes short-distance communication connection with the vehicle.
And S105, determining the using state of the vehicle according to the connection state of the short-distance communication connection.
And S107, executing corresponding preset functions according to the determined using state of the vehicle.
The user starts the vehicle, the vehicle circuitry is powered on, and the short-range communication module of the vehicle is powered on. After a terminal carried by a user establishes short-distance communication connection with a vehicle, the terminal monitors the connection state of the short-distance communication connection, and when the connection state is connected, the terminal determines that the vehicle is in a starting state; when the connection state is disconnected, the terminal determines that the vehicle is in a parking state. And the terminal executes corresponding preset functions according to different use states of the vehicle. To better explain the present solution, the following describes the implementation process of the present embodiment by taking bluetooth connection as an example:
a user carries a terminal for starting the Bluetooth module to enter a vehicle, after the vehicle is started, the Bluetooth module of the vehicle is electrified to work, and the terminal is connected with the vehicle in a Bluetooth mode. Specifically, if the terminal is bluetooth paired with the vehicle for the first time, the user is required to manually configure to establish a bluetooth connection. If the terminal is successfully connected with the vehicle through the paired Bluetooth, the Bluetooth identity information of the vehicle is stored in the terminal, and the terminal directly establishes Bluetooth connection with the vehicle.
Furthermore, if the terminal is connected with other Bluetooth devices such as a Bluetooth headset and the like, the priority of vehicle-mounted Bluetooth is preset in the terminal to be the highest, and the situation that when the terminal is connected with the Bluetooth headset in a matched mode and then enters a vehicle, the terminal cannot be connected with a vehicle-mounted Bluetooth module of the vehicle is avoided.
After the terminal establishes Bluetooth connection with the vehicle, the terminal identifies the identity information of the vehicle-mounted Bluetooth. The identity information can be the Bluetooth type of the vehicle-mounted Bluetooth and can also be the unique identification information of the vehicle-mounted Bluetooth. According to the SPECIFICATION of Bluetooth Version 4.2 protocol (BLUETOOTH SPECIFICATION Version 4.2), "Minor Device Class field" field in the Bluetooth Device "Class of Device" specifies the Bluetooth Class of the Device, e.g., the default value of "Minor Device Class field" field in the onboard Bluetooth "Class of Device" is 001000. Therefore, after the terminal establishes connection with the vehicle, the terminal can determine whether the Device is the vehicle by identifying the preset value of the 'Minor Device Class field' field of the Device connected with the terminal, and if the Device is the vehicle, the step S105 is executed. The terminal has various ways of identifying the identity information of the vehicle-mounted Bluetooth, and also directly inquires whether the equipment is the vehicle-mounted Bluetooth or not for manual selection of a user; or whether the unique identification information (the identification information of the bluetooth device is "bluetooth device address") for identifying the device is preset identification information, and the like.
The terminal monitors the connection state of the short-distance communication connection between the terminal and the vehicle, and determines the use state of the vehicle according to the connection state. There are various methods for determining the use state of the vehicle by the terminal according to the connection state, and specific examples are as follows:
1. if the connection state of the short-range communication connection between the terminal and the vehicle is connected, the use state of the vehicle is determined to be the activation state.
The short-distance communication connection module of the vehicle is in a power-on working state and the vehicle is in use, so that the use state of the vehicle is determined to be the starting state. When the vehicle is temporarily parked under the conditions of red light, pedestrians and the like, the vehicle is still in use, the connection state of the short-distance communication connection between the terminal and the vehicle is connected, and the terminal can still determine that the use state of the vehicle is the starting state. Therefore, the problem that when the terminal judges the use condition of the vehicle according to the running speed of the vehicle in the prior art, the vehicle is mistakenly judged to be the user to get off when the vehicle stops temporarily can be solved.
2. And if the connection state of the short-distance communication connection between the terminal and the vehicle is disconnected, determining that the use state of the vehicle is a flameout state.
When the vehicle is switched off, the short-range communication module of the vehicle is powered off, so that the established short-range communication connection between the vehicle and the terminal is disconnected, and when the terminal monitors that the connection state is disconnected, the use state of the vehicle is determined to be a switching-off state.
3. And if the connection state of the short-distance communication connection between the terminal and the vehicle is disconnected, and the terminal detects that the movement speed of the terminal is less than a first preset speed and/or determines that the terminal is in a walking state, determining that the use state of the vehicle is a flameout state.

S203, the terminal establishes short-distance communication connection with the vehicle.
S205, monitoring the connection state of the short-range communication connection.
If the connection state of the short-distance communication connection between the terminal and the vehicle is connected, the step S221 is entered, and the using state of the vehicle is determined to be the starting state; if the connection state of the short-range communication connection between the terminal and the vehicle is disconnected, it proceeds to step S207 or S213.
S207, detecting whether the movement speed of the terminal is smaller than a first preset speed and/or determining whether the terminal is in a walking state.
If the moving speed of the terminal is less than the first preset speed or it is determined that the terminal is in the walking state, it goes to step S209.
And S209, initiating a short-range communication connection request to the vehicle at least once within a first preset time.
And S211, determining whether the short-distance communication connection is reestablished between the terminal and the vehicle within the first preset time.

And S223, determining the using state of the vehicle as a flameout state.
The user starts the vehicle, the vehicle circuitry is powered on, and the short-range communication module of the vehicle is powered on. After a terminal carried by a user establishes short-distance communication connection with a vehicle, the terminal monitors the connection state of the short-distance communication connection, and when the connection state is connected, the terminal determines that the vehicle is in a starting state. When the connection state is disconnected, the terminal detects whether the movement speed of the terminal is zero or the pace speed.
And if the connection is disconnected and the movement speed of the terminal is less than the first preset speed or the terminal is determined to be in a walking state, the vehicle is considered to be static. In order to prevent the vehicle from parking temporarily and the short-distance communication connection is interrupted unexpectedly, the short-distance communication connection request is initiated to the vehicle at least once within the first preset time. And if the short-distance communication connection is reestablished between the terminal and the vehicle within the first preset time, determining that the using state of the vehicle is the starting state. And if the short-distance communication connection cannot be reestablished between the terminal and the vehicle within the first preset time, determining that the using state of the vehicle is a flameout state, namely that the user flameout and gets off the vehicle. Therefore, the situation that the vehicle is accidentally flamed out and then immediately ignited, and the signal is interrupted when the vehicle is temporarily stopped without flameout is eliminated, and the terminal judges that the vehicle is in a flameout state.
Optionally, the terminal detects whether the terminal is in a walking state through an AR Sensor (Activity Recognition Sensor) integrated with the terminal, and if the terminal is detected to be in the walking state, it may be determined that the user has got off the vehicle.
Alternatively, if the connection is disconnected and it is determined that the terminal is in the walking state, the use state of the vehicle is directly determined to be the key-off state.
If the connection is disconnected, the movement speed of the terminal is not greater than the second preset speed and/or the terminal is in the vehicle-mounted state, the vehicle is still considered to be in the starting state, and the short-distance communication connection is unexpectedly interrupted due to signal problems. Thus initiating a short-range communication connection request to the vehicle at least once within a second preset time. And if the short-distance communication connection is reestablished between the terminal and the vehicle within the second preset time, determining that the using state of the vehicle is the starting state. And if the short-distance communication connection between the terminal and the vehicle can not be reestablished within the second preset time, prompting the user that the short-distance communication signal is interrupted and prompting the user to check. The method and the device prevent the accidental interruption of signals between the terminal and the vehicle, so that the vehicle is judged to be in a flameout state by mistake.
Or, if the connection is disconnected, and the movement speed of the terminal is greater than the second preset speed and/or the terminal is in the vehicle-mounted state, the use state of the vehicle can be directly determined to be the starting state. And continuously initiating a short-distance communication connection request to the vehicle within the next second preset time, and if the short-distance communication connection cannot be reestablished between the terminal and the vehicle within the second preset time, prompting the user that the short-distance communication signal is interrupted and prompting the user to check. The method and the device prevent the accidental interruption of signals between the terminal and the vehicle, so that the vehicle is judged to be in a flameout state by mistake.
It should be noted that the second predetermined time may be much longer than the first predetermined time, for example, the first predetermined time is five seconds, and the second predetermined time is five minutes.

Or starting a navigation application to perform destination navigation. The destination can be a destination which is automatically input into the navigation application by the user, can also be a destination which is automatically input by the terminal according to the driving habits of the user, and can also be a destination which is inquired according to schedule information in the calendar application. For example, the terminal determines the current time of leaving work and returning home for the user according to the current time, and automatically inputs the home address of the user in the navigation application for navigation.
Or the terminal inquires weather service through data service, and prompts whether the client needs to start the air conditioner or not by voice according to the weather forecast temperature of the day and a pre-designed temperature threshold.
Or the terminal inquires schedule information in the calendar application and prompts the user for the calendar schedule.
When the terminal determines that the vehicle is in a flameout state, a second preset function is executed, for example, the second preset function is as follows:
for example, the GPS function on the terminal is turned on (if already turned on, no turn-on action needs to be performed), and the current GPS information of the terminal is automatically acquired and saved. It can be known that the current GPS information of the terminal is the GPS information of the vehicle parking place when the terminal determines that the vehicle is parked. When a user gets the vehicle, the parking place can be quickly found according to the GPS information.
In order to quickly record the current GPS information, the GPS function may be turned on to record the current GPS information when the short-range communication connection is disconnected.
Optionally, the terminal acquires a vehicle taking instruction and displays the stored current GPS information. The user quickly finds a parking place.
Or, a player on the terminal is started, and voice information preset in the terminal is played, for example, a user is reminded to record information such as a parking pile of a parking lot.
Or starting the photographing application to allow the user to photograph and record the parking position.
Or inquiring weather information, and prompting whether a customer needs to wear a coat, take an umbrella and the like by voice according to the weather forecast temperature of the day and a pre-designed temperature threshold value.
The first preset function and the second preset function can be set by a user or a terminal system. The first preset function and the second preset function may be any functions allowed to be executed on the terminal, and specific contents of the first preset function and the second preset function are not limited herein.
