Description:FIELD OF THE INVENTION
[001] The present invention relates to a vehicle system for controlling a Bluetooth of a user device.

BACKGROUND OF THE INVENTION
[002] The integration of a user devices such as mobile phones, personal assistant devices to vehicle systems such as infotainment system or information cluster display has become increasingly prevalent in modern automotive technology. Bluetooth technology has become ubiquitous in modern electronic devices, enabling seamless wireless communication between devices in proximity. The user device connects with the infotainment system using Bluetooth and various functionalities of the vehicle system are enabled on a display of the infotainment system or the instrument cluster only after successful connection with the user device.
[003] Several key issues have been identified within the existing systems which include Bluetooth auto reconnection failures disrupting the seamless connectivity between devices. Furthermore, the existing systems are inefficient in accurately determining the Bluetooth state in the user device which poses a significant challenge, hampering the effectiveness of the vehicle system. Additionally, operating the existing systems turns into an annoying user experience, owing to the reasons that the paired user device is disconnected from the information cluster. This issue is exacerbated by instances where Bluetooth on the user device is found to be switched off, leading to frustration and inconvenience to users. Controlling manually the Bluetooth connection of the paired user devices with the vehicle system has been observed to be a cumbersome task and often requires repetitive manual intervention which is undesirable and also inconvenient. The infotainment system fails to connect with the user device if the Bluetooth of the user device is in deactivated or OFF state. In such a condition, a user has to manually turn the Bluetooth ON of the user device to connect with the vehicle system. However, if the user has already started driving the vehicle, it poses a serious safety risk to connect the Bluetooth while driving the vehicle. When the Bluetooth of the user device is in deactivated state, the vehicle system automatically attempts to reconnect to the user device and gives up after a set number of times resulting in auto reconnection failure.
[004] Thus, there is a need for a vehicle system for controlling a Bluetooth of a user device, which address at least one of the aforesaid problems or drawbacks.

[032] In an embodiment, the one or more communication channels are selected from a wired communication, a cloud communication, a Wi-Fi network communication, a near-field communication (NFC) and a cellular network communication. In a non-limiting example, the primary communication channel being the cloud communication, when the cloud communication fails, the communication unit 110 attempts to activate the Bluetooth module 210 using the Wi-Fi network communication. When the attempt to activate the Bluetooth module 210 fails, the communication unit 110 attempts to activate the Bluetooth module 210 using the cellular network communication.

[036] Figure 3 is a flow diagram showing a method 300 for controlling the Bluetooth of the user device, in accordance with an exemplary embodiment of the present invention. The method 300 is performed by the Bluetooth controller 120 of the user device 200. At step 310, the Bluetooth controller 120 detects the presence of a user within the vicinity of the vehicle. At step 320, the Bluetooth controller 120 determines the operating state of a Bluetooth module 210 of a user device 200. At step 330, the Bluetooth controller 120 sends a control signal to the user device 200 for activating/deactivating the Bluetooth module 210 of the user device 200.
[037] Figure 4 is a flow diagram showing a method 400 for controlling the Bluetooth of the user device 200 using a cloud application, in accordance with an exemplary embodiment of the present invention. The method 400 is performed using the communication unit 110, a cloud application running on a server in a cloud infrastructure setup and the user device 200. When the user of the vehicle approaches the vehicle with the user device 200, the vehicle system 100 detects the user device. In a non-limiting example, the software application on the user device is always connected to the cloud application. The communication unit 110 attempts to connect to the user device 200 by sending a connect signal through the means of receiving and sending signals to the communication unit 110. If the connection is not successful, then return (NOK) signal is sent to the communication unit 110 from the user device 200 through the means of receiving and sending signals to the communication unit 110. Then the communication unit 110 sends a check Cloud Connection signal to check the connection between the communication unit 110 and the cloud application. If the connection is successful, the cloud application sends the return signal (OK) to the communication unit 110.
[038] Upon successful connection, the communication unit 110 sends check BTStatus signal to the cloud application to the user device 200 through the cloud application. If the Bluetooth module 210 of the user device 200 is in OFF condition, then the return(OFF) signal is sent to the communication unit 110 through the cloud application. Then the communication unit 110 sends enableBT signal to the user device 200 through the cloud application to activate the Bluetooth module 210 of the user device 200. Then the user device 200 sends return(ON) signal to the communication unit 110 through the cloud application. Upon activation of Bluetooth module 210 in the user device 200, the communication unit 110 sends connect signal to the user device 200 and the connection is successfully established between the communication unit 110 and user device 200. The user device 200 then sends return(OK) signal to the communication unit 110 upon successful connection .In an embodiment, once the enableBT signal is sent to the user device 200, the user device 200 is discoverable and connectable for a short time during which the communication unit 110 is successfully connected with the Bluetooth module 210 of the user device 200.
[039] Figure 5 is a flow diagram showing a method 500 for controlling the Bluetooth of the user device 200 using Wi-Fi, in accordance with an exemplary embodiment of the present invention. The method 500 is performed on the communication unit 110 and user device 200 when the connection through the cloud application fails. The user of the vehicle approaches the vicinity of the vehicle and the user device 200 having the internet connectivity and the software application is installed on the user device 200. The software application on the user device 200 is always connected to the cloud application. But the connection between the software application and cloud application is dependent on internet connection. In case the cloud application connectivity failure occurs due to poor or no internet connectivity or if the cloud application is not functioning properly, the communication unit 110 attempts to connect to the user device 200 by sending the connect signal through the means of receiving and sending signals to the communication unit 110. If the connection is not successful, then return(NOK) signal is sent to the communication unit 110 from the user device 200 through the means of receiving and sending signals to the communication unit 110.Then the communication unit 110 sends the check Cloud Connection signal to check the connection between the communication unit 110 and the cloud application. If the connection is unsuccessful, the cloud application returns return(NOK) signal to the communication unit 110. Upon unsuccessful connection, the communication unit 110 sends wifiConnect signal to the user device 200 to establish connection over Wi-Fi with the user device 200. If the connection is established successfully, the user device 200 sends return(OK) to the communication unit 110.
[040] Upon successful connection, the communication unit 110 sends checkBTStatus() signal to the cloud application to the user device 200 through the cloud application. If the Bluetooth module 210 of the user device 200 is in OFF condition, then the return(OFF) signal is sent to the communication unit 110.
[041] Then the communication unit 110 sends the enableBT() signal to the user device 200 to activate the Bluetooth module 210 of the user device 200. Then the user device 200 sends return(ON) signal to the communication unit 110.
[042] Upon activation of Bluetooth module 210 in the user device 200, the communication unit 110 sends connect() signal to the user device 200 and the connection is successfully established between the communication unit 110 and user device 200. The user device 200 then sends return(OK) signal to the communication unit 110 upon successful connection. In an embodiment, once the enableBT() signal is sent to the user device 200, the user device 200 is discoverable and connectable for a short while during which the communication unit 110 is enabled to successfully connect with the user device 200.
[043] In a non-limiting example, a software application capable of Wi-Fi technology and configured with technology defined modes residing in both the communication unit 110 and the user device 200 may be used to enable Bluetooth module 210 of the user device 200.
[044] Figure 6 is a flow diagram showing a method 600 for controlling the Bluetooth of the user device 200 using SMS communication channel, in accordance with an exemplary embodiment of the present invention. The method 600 is performed with the vehicle system 100 when the connection through the cloud application and the Wi-Fi communication channel fails.
[045] The communication unit 110 attempts to connect to the user device 200 by sending the connect() signal through the means of receiving and sending signals to the communication unit 110. If the connection is not successful, then return (NOK) signal is sent to the communication unit 110 from the user device 200 through the means of receiving and sending signals to the communication unit 110.
[046] Then the communication unit 110 sends the checkCloudConnection() signal to check the connection between the communication unit 110 and the cloud application. If the connection is unsuccessful, the cloud application sends return(NOK) signal to the communication unit 110.
[047] Upon unsuccessful connection, the communication unit 110 sends wifiConnect() signal to the user device 200 to establish connection over the Wi-Fi communication channel with the user device 200. If the connection is unsuccessful, the user device 200 sends return(NOK) signal to the communication unit 110. Then the communication unit 110 sends SMS(BTON) signal to the user device 200 through the SMS enabled through a cellular network of the user device to activate the Bluetooth module 210 of the user device 200. Accordingly, the Bluetooth module 210 of the user device 200 is activated and the user device 200 returns SMS(BTSTATEON) signal to the communication module 110 to indicate the Bluetooth unit 210 of the user device 200 is activated.
[048] Upon activation of Bluetooth module 210 in the user device 200, the communication unit 110 sends connect() signal to the user device 200 and the connection is successfully established between the communication unit 110 and user device 200. The user device 200 then sends return(OK) signal to the communication unit 110 upon successful connection. In an embodiment, once the SMS(BTON) signal is sent to the user device 200, the user device 200 is discoverable and connectable for a short while during which the communication unit 110 successfully makes Bluetooth connection with the user device 200.
[049] In an embodiment, when the enableBT signal in the user device 200 fails even after using the cloud application Wi-Fi application, the software application capable of reading and sending SMS provided with both the communication unit 110 and user device 200 enables the Bluetooth module 210 in the user device 200 in such conditions.
[001] Advantageously, the present invention provides an efficient vehicle system for activating/ deactivating a Bluetooth module of a user device selectively through the one or more communication channels based on the operating state of the Bluetooth module of the user device. The system of the present invention improves the performance, ease of comfort as well as the user experience by establishing a successful Bluetooth connection automatically or with minimum manual intervention.
