As described above, in the conventional scheme of the method for vehicle interaction, there is a case where the user terminal does not actually support the counter control by the vehicle-mounted device due to hardware configuration or software setting, but the vehicle-mounted device cannot identify the user terminal that can be normally interconnected with the vehicle-mounted device but does not support the counter control of the vehicle-mounted device, and cannot assist the user in confirming whether there is an interconnection manner supporting the counter control of the vehicle-mounted device.
To at least partially address one or more of the above issues and other potential issues, an example embodiment of the present disclosure proposes a solution for vehicle interaction. The scheme comprises the following steps: in response to displaying first connection information at a touch screen of an on-vehicle device of a vehicle, detecting an operation action applied to the touch screen of the on-vehicle device and aiming at an object mapped to the touch screen by a user terminal, wherein the first connection information is used for indicating that a wireless communication connection is established between the on-vehicle device and the user terminal; determining whether the device attribute information of the user terminal belongs to a pre-stored preset set; and in response to determining that the device attribute information of the user terminal belongs to the predetermined set, displaying first indication information at the touch screen, the first indication information indicating that the user terminal does not support wireless manipulation by the touch screen.
In the scheme, the wireless communication connection between the vehicle-mounted device and the user terminal is determined through the first connection information, and when an operation action of a user on a screen projection object of the user terminal is detected on a touch screen of the vehicle-mounted device, if the acquired device attribute information of the user terminal is determined to belong to a preset set, the first indication information is displayed on the touch screen to indicate that the user terminal does not support reverse control in a wireless mode through the touch screen.

Regarding the wireless communication connection confirmation unit 132, it is configured to display first connection information indicating that a wireless communication connection is established between the in-vehicle apparatus 130 and the user terminal 120.
A device attribute information acquisition unit 134 for confirming whether an operation action applied to the touch screen of the in-vehicle device 130 for an object mapped on the touch screen by the user terminal 120 is detected; if an operation action applied to the touch screen of the in-vehicle device 130 for an object mapped on the touch screen by the user terminal 120 is detected, device attribute information of the user terminal 120 is acquired.
A predetermined set determination unit 136 for determining whether the device attribute information of the user terminal 120 belongs to a predetermined device set stored in advance.
A first indication information display unit 138 for transmitting a first test signal to the user terminal 120 via the application program interface of the user terminal 120 if it is determined that the device property information of the user terminal 120 does not belong to the predetermined device set, the first test signal being associated with the operation action, the first indication information indicating that the user terminal does not support wireless manipulation by the touch screen; and if the response signal of the user terminal to the first test signal is determined not to be received within the first preset time interval, displaying at least one of first indication information and second indication information at the touch screen, wherein the second indication information is used for indicating that the user terminal 120 is to be connected with the vehicle-mounted device through the USB connection mode.
With respect to the first test signal sending unit 140, it is configured to send a first test signal to the user terminal 120 via the application program interface of the user terminal 120, the first test signal being associated with the operation action, if it is determined that the user terminal 120 does not belong to the predetermined set of devices.
And a response signal confirmation unit 142 for determining whether a response signal of the user terminal 120 to the first test signal is not received within a first predetermined time interval.
As to the user terminal 120, it is, for example, but not limited to, a mobile phone. The mobile device 120 can directly interact and share data with the in-vehicle device 130 through bluetooth, USB and other wireless or wired interconnection modes. Data interaction with the server 160 may also be via the base station 150, the network 170. The user terminal 120 may project the displayed content onto the touch screen of the in-vehicle device 130. When the user terminal 120 is a cellular phone, it may include an application program interface 122, a bluetooth module 124, a video playback unit 126, and other units not shown. The user terminal 120 may be implemented by the computing device 600 shown in fig. 6.
With respect to the application program interface 122, for example and without limitation, data interaction with the in-vehicle device 130 is enabled. Specifically, the in-vehicle device 130 may acquire device attribute information of the user terminal 120 through the application interface 122, for example; and obtains the number of historical bluetooth paired devices in the bluetooth paired list of the user terminal 120 through the application interface 122.
Regarding the bluetooth module 124, it is used for the user terminal 120 and the in-vehicle device 130 to perform bluetooth connection and data interaction. The bluetooth module 124 includes, for example, at least a protocol layer and an underlying hardware module. The protocol layer is composed of, for example, a Bluetooth specific protocol specified by the Bluetooth Special Interest Group (SIG). The underlying hardware modules include, for example: the system comprises a wireless radio frequency module, a baseband module, a link control module, a link management module and a host controller interface. Radio frequency modules (radios) are used for data reception and transmission. The BaseBand module (BaseBand) is used for wireless medium access conventions, providing synchronous connection-oriented physical links and asynchronous connectionless physical links. A Link Control (LC) module is used for encoding and decoding of bluetooth data packets. And the Link Management (LM) module is used for creating, modifying and issuing logical links and updating physical Link parameters between the devices. Host Controller Interface (HCI) is used to provide a command Interface for the baseband Controller, connection manager, hardware status and control registers. For example, pairing interconnection is achieved with an in-vehicle bluetooth device of the in-vehicle device 130 via the bluetooth module 124. The in-vehicle device 130 may obtain the identifier of the user terminal 120 and the bluetooth pairing password; the data connection of the user terminal 120 and the personal hotspot function are then configured to be opened so that the in-vehicle device 130 can scan to the user terminal 120 for the interconnection.
As for the video playing unit 126, it is used to play a video file stored locally or acquired online by the user terminal, for example. The user terminal 120 supports, for example, a Mobile terminal High-Definition Link (MHL) function, via which a video signal played by the user terminal 120 can be transmitted to a touch screen of the in-vehicle device 130. For example, the USB interface of the user terminal 120 and the HDMI interface of the in-vehicle device 130 may be simultaneously connected through the MHL line to implement mapping of a video signal screen played by the user terminal 120 to the touch screen of the in-vehicle device 130.
A method for vehicle interaction according to an embodiment of the present disclosure will be described below in conjunction with fig. 2. Fig. 2 shows a flow diagram of a method 200 for vehicle interaction, according to an embodiment of the present disclosure. It should be understood that the method 200 may be performed, for example, at the computing device 600 depicted in fig. 6. May also be implemented at the onboard device 130 depicted in fig. 1. It should be understood that method 200 may also include additional acts not shown and/or may omit acts shown, as the scope of the disclosure is not limited in this respect.
At step 202, if first connection information is displayed at a touch screen of the vehicle-mounted device, whether an operation action applied to the touch screen of the vehicle-mounted device and aiming at an object mapped to the touch screen by the user terminal is detected, wherein the first connection information is used for indicating that a wireless communication connection is established between the vehicle-mounted device and the user terminal.
Regarding the object mapped on the touch screen by the user terminal, for example and without limitation, the object is a video player which is played by the user terminal and is projected on the touch screen of the vehicle-mounted device and a video played by the user terminal.
Regarding the operation action, for example and without limitation, it is a dragging of a play progress bar for a screen player projected onto a touch screen of the in-vehicle apparatus. The operation action may also be a click operation for an icon in a display interface of the user terminal that is projected onto the touch screen of the in-vehicle device.
At step 204, if the vehicle-mounted device detects an operation action applied to a touch screen of the vehicle-mounted device and aiming at an object mapped to the touch screen by the user terminal, whether the device attribute information of the user terminal belongs to a pre-stored preset set is determined.
As to the manner of acquiring the device attribute information of the user terminal, it includes, for example: the vehicle-mounted device obtains the docket model of the user terminal through an Application Programming Interface (API).
As for the predetermined device set, it includes, for example, a set of device attribute information that does not support a user terminal wirelessly operated by each in-vehicle device. The device attribute information is, for example, a docket number of the user terminal.
At step 206, if the vehicle-mounted device determines that the device attribute information of the user terminal belongs to the preset set, first indication information is displayed on the touch screen, and the first indication information is used for indicating that the user terminal does not support being manipulated in a wireless mode through the touch screen.
In one possible example, if the in-vehicle device determines that the device attribute information of the user terminal does not belong to the predetermined set, sending a first test signal to the user terminal via an application program interface of the user terminal, the first test signal being associated with the operation action; and the vehicle-mounted equipment determines that a response signal of the user terminal to the first test signal is not received within a first preset time interval, and displays at least one of the first indication information and the second indication information at the touch screen.
As regards the response signal to the first test signal, this is for example the result of a processing with respect to the operating action or an associated interaction signal. Research shows that feedback information of an application program interface of a user terminal which does not support wireless control by each vehicle-mounted device can indicate that the vehicle-mounted device and the user terminal are compatible and can normally carry out wireless interconnection. However, the feedback information of the application program interface cannot reflect whether the user terminal does not support the reverse control by the vehicle-mounted device. Research shows that the Bluetooth module of the user terminal can not support wireless control of each vehicle-mounted device due to reasons such as the fact that a bottom hardware module is not adaptive; or the wireless control of each vehicle-mounted device cannot be supported temporarily due to the fact that the number of historical Bluetooth device pairs of the user terminal is too large. Therefore, the vehicle-mounted device can detect whether the processing result related to the operation action or the associated interaction signal is not received within the first preset time interval, and can accurately judge whether the current user terminal is in a state of not supporting the wireless control of the vehicle-mounted device.
In one possible example, if the vehicle-mounted device determines that a response signal of the user terminal to the first test signal is not received within a first predetermined time interval, at least one of first indication information and second indication information is displayed at the touch screen, wherein the second indication information is used for indicating that the user terminal is to be connected with the vehicle-mounted device via a USB connection mode.
And if the vehicle-mounted equipment determines that the response signal of the user terminal to the first test signal is not received within the first preset time interval. The vehicle-mounted device may determine that the current user terminal is in a state that the wireless manipulation by each vehicle-mounted device is not supported, and display indication information (such as an indication word or an indication icon) indicating that the current user terminal does not support the wireless manipulation by the vehicle-mounted device and/or indication information (such as an indication word or an indication icon) indicating that the user terminal is replaced with the USB connection manner at the touch screen. The purpose of displaying the instruction information for instructing the user terminal to be replaced with the USB connection manner at the touch screen is that some user terminals do not support the wireless manipulation by the in-vehicle apparatus but support the USB connection manner by the in-vehicle apparatus. By adopting the means, the method and the device can remind the user whether the user can try to support the reverse control of the USB connection mode or not when the user terminal is confirmed not to support the reverse control of the wireless mode.
In one possible example, if the vehicle-mounted device determines that a response signal of the user terminal to the first test signal is received within a first preset time interval, displaying and presenting the response signal at the touch screen.
In the scheme, when the vehicle-mounted device and the user terminal are determined to be interconnected and the operation action of the screen projection object of the user terminal on the touch screen of the vehicle-mounted device is detected, if the acquired device attribute information of the user terminal is determined to belong to the preset set, the first indication information is displayed on the touch screen to indicate that the user terminal does not support wireless counter control by the touch screen. The method and the device can rapidly identify the registered user terminal which does not support the reverse control of the vehicle machine and indicate the user terminal to the user. Additionally, if it is determined that the device attribute information does not belong to the predetermined set, sending a first test signal associated with the operation action via an application program interface of the user terminal; if it is determined that the response signal to the first test signal is not received within the first predetermined time interval, displaying, at the touch screen, first indication information indicating that the user terminal does not support wireless manipulation by the touch screen, and/or second indication information indicating that the user terminal is to be connected to the in-vehicle device via the USB connection. Therefore, even for a new model of user terminal that is not registered, the present disclosure can accurately identify a user terminal that does not support wireless mode back control of the in-vehicle device, and instruct the user terminal to attempt USB mode back control. Therefore, the method and the device can identify the user terminal which does not support the reverse control of the vehicle-mounted equipment, and assist the user to confirm whether the user terminal supports the reverse control interconnection mode of the vehicle-mounted equipment.
In some embodiments, the method 200 further comprises: and if the vehicle-mounted device determines that at least one of the first indication signal and the fourth indication signal is displayed at the touch screen, adding device attribute information of the user terminal to a preset device set, wherein the preset device set is obtained from the cloud server. Therefore, the cloud server can update the preset set of the device attribute information of the user terminals which do not support the reverse control of the vehicle-mounted devices at any time based on the information fed back by the vehicle-mounted devices, so that the preset set of the device attribute information can be used for identifying the user terminals which do not support the reverse control of the vehicle-mounted devices by the vehicle-mounted devices.
In some embodiments, the method 200 further includes a method 300 of displaying at least one of the first and second indication information. Fig. 3 illustrates a flow chart of a method 300 of displaying at least one of first and second indication information in accordance with an embodiment of the present disclosure. It should be understood that the method 300 may be performed, for example, at the computing device 600 depicted in fig. 6. May also be implemented at the onboard device 130 depicted in fig. 1. It should be understood that method 300 may also include additional acts not shown and/or may omit acts shown, as the scope of the disclosure is not limited in this respect.
At step 302, the vehicle-mounted device determines that a response signal of the user terminal to the first test signal is not received within a first predetermined time interval.
At step 304, the in-vehicle device determines whether the number of history bluetooth paired devices indicated in the bluetooth paired list of the user terminal is less than a predetermined number threshold.
The research finds that the reason that the user terminal does not support the reverse control of the vehicle-mounted equipment comprises the reason of hardware configuration and also comprises the reason of software configuration. The reason for the software configuration includes, for example, that if the number of the historical bluetooth paired devices of the user terminal is too large, even if the historical bluetooth paired devices are not connected currently, the function of controlling the user terminal by the vehicle-mounted device cannot be realized. Therefore, if the vehicle-mounted device detects that the number of the historical Bluetooth paired devices exceeds the preset number threshold, the user can be prompted to delete the number of the historical Bluetooth paired devices so as to eliminate and avoid the condition that the anti-control is not supported due to the reason of software configuration. As for the predetermined number threshold, it is 7, for example.
At step 306, if the vehicle-mounted device determines that the number of historical Bluetooth paired devices indicated in the Bluetooth pairing list of the user terminal is less than a preset number threshold, at least one of the first indication information and the second indication information is displayed at the touch screen.
If the number of the historical Bluetooth pairing equipment does not exceed the preset number threshold value, the reason in the aspect of software configuration can be eliminated, the fact that the hardware of the user terminal does not support the vehicle-mounted equipment to perform reverse control in a Bluetooth mode is determined and indicated, and the user can also be indicated to interconnect the user terminal and the vehicle-mounted equipment in a USB mode at the same time, so that whether the hardware of the user terminal supports the vehicle-mounted equipment to perform reverse control in a USB connection mode or not is identified.
In the scheme, the method and the device can quickly identify and check whether the user terminal which does not support the reverse control of the vehicle-mounted equipment is caused by too many historical Bluetooth paired equipment.
Fig. 4 shows a flowchart of a method 400 of displaying third indication information according to an embodiment of the present disclosure. It should be understood that the method 400 may be performed, for example, at the computing device 600 described in fig. 6. May also be implemented at the onboard device 130 depicted in fig. 1. It should be understood that method 400 may also include additional acts not shown and/or may omit acts shown, as the scope of the disclosure is not limited in this respect.
At step 402, if the vehicle-mounted device determines that the number of the historical Bluetooth paired devices is greater than or equal to the preset number threshold value, third indication information is displayed at the touch screen, and the third indication information is used for indicating that the number of the historical Bluetooth paired devices in the Bluetooth connection list is reduced.
Research shows that if too many historical bluetooth paired devices of the user terminal are available, even if the historical bluetooth paired devices are not connected currently, the function of reversely controlling the user terminal by the vehicle-mounted device cannot be realized. Therefore, if the vehicle-mounted device determines that the number of the historical bluetooth paired devices is greater than or equal to 7, third indication information is presented on a touch screen of the vehicle-mounted device to remind a user to partially delete the historical bluetooth paired devices in the bluetooth paired list.
At step 404, the in-vehicle device determines whether the number of historic bluetooth paired devices is reduced to less than a predetermined number threshold.
At step 406, if the in-vehicle device determines that the number of the historical bluetooth paired devices is reduced to less than the predetermined number threshold, the first test signal is again transmitted to the user terminal via the application program interface of the user terminal for determining whether a response signal of the user terminal to the first test signal is received within a first predetermined time interval.
For example, if the in-vehicle device determines that the number of the historical bluetooth paired devices of the user terminal is less than 7, the first test signal associated with the aforementioned operation signal is transmitted again, so as to test again whether the user terminal adjusted the bluetooth paired list supports the in-vehicle device override. If the vehicle-mounted equipment determines that the response signal of the user terminal for the retransmitted first test signal is still not received within the first preset time interval, the fact that the user terminal belongs to hardware does not support the reverse control of the vehicle-mounted equipment is indicated.
In the scheme, the method and the device can prompt the user to confirm whether the user belongs to the user terminal supporting the vehicle-mounted equipment to reversely control on hardware or not by reducing historical Bluetooth pairing equipment.
Fig. 5 illustrates a flow chart of a method 500 of displaying fourth indication information according to an embodiment of the present disclosure. It should be understood that the method 500 may be performed, for example, at the computing device 600 described in fig. 6. May also be implemented at the onboard device 130 depicted in fig. 1. It should be understood that method 500 may also include additional acts not shown and/or may omit acts shown, as the scope of the disclosure is not limited in this respect.
At step 502, if the vehicle-mounted device determines that second connection information is displayed at the touch screen of the vehicle-mounted device, the second connection information is displayed at the touch screen of the vehicle-mounted device, and a second test signal is sent to the user terminal, the second connection information being used for indicating whether the user terminal is connected to the vehicle-mounted device in a USB connection mode or not, and the second test signal is associated with the user terminal being manipulated in the USB connection mode through the touch screen.
In some embodiments, if the in-vehicle device determines that the user terminal is not connected to the in-vehicle device via the USB connection, the step 502 is continued until it is determined that the user terminal is connected to the in-vehicle device via the USB connection.
Regarding the second test signal, it is associated with the operation action applied on the touch screen of the vehicle-mounted device for the object mapped on the touch screen by the user terminal, as mentioned in the foregoing embodiment. The second test signal is different from the first test signal for testing the wireless mode counter control.
At step 504, the vehicle-mounted device determines whether a response signal of the user terminal to the second test signal is not received within a second predetermined time interval.
At step 506, if the vehicle-mounted device determines that a response signal of the user terminal to the second test signal is not received within a second predetermined time interval, it is determined whether a target object in an image displayed on a touch screen of the vehicle-mounted device meets a condition, where the target object is used for indicating a position of the image.
At step 508, if the target object in the image displayed on the touch screen of the vehicle-mounted device meets the condition, fourth indication information is displayed on the touch screen, and the fourth indication information is used for indicating that the user terminal cannot be operated in a USB connection mode through the touch screen.
Studies have shown that if a user terminal is not able to be manipulated via a touch screen in a USB connection, a cursor is typically displayed on the touch screen. Therefore, the in-vehicle device 130 may determine whether the user terminal cannot be manipulated in the USB connection manner via the touch screen by acquiring an image displayed on the touch screen by screen copy or the like and then recognizing a target object indicated by the image.
The in-vehicle apparatus determining that the target object indicated by the image meets the predetermined condition includes one of: determining that the matching degree of the target object indicated by the image and a predetermined template is greater than a predetermined matching degree threshold value, wherein the predetermined template is associated with a cursor image; predicting, via a multi-sample trained target object recognition model, that a class of a target object indicated by the image is a cursor.
As for the predetermined condition, it is, for example, that the prediction category of the target object is a cursor. The predetermined condition may also be that the image including the target object matches a predetermined template (e.g., a cursor image).
As for the manner of determining the target object indicated by the image, it is determined whether the matching degree of the target object indicated by the image with a predetermined template is less than a predetermined matching degree threshold, for example, by template matching. The manner of determining the target object indicated by the image may also be to predict whether the class of the target object is a cursor via a multi-sample trained target object recognition model. The target object recognition model is constructed, for example, based on a Neural Network model (e.g., without limitation, a Convolutional Neural Network (CNN) model).
In some embodiments, the in-vehicle device determines whether a degree of matching of the target object indicated by the image with a predetermined template is greater than a predetermined degree of matching threshold, for example, by template matching. Specifically, the vehicle-mounted device may move the predetermined template on the acquired image to be recognized from left to right and pixel by pixel from top to bottom, calculate a matching degree of the predetermined template image and the overlapping sub-image of the image to be recognized, and the greater the matching degree, the greater the possibility that the predetermined template is the same as the overlapping sub-image.
Regarding the manner of calculating the degree of matching, the in-vehicle device may perform the degree of matching calculation using the square difference.
A method of performing the matching degree calculation using the squared difference is described below with reference to formula (1).
R(x，y)＝∑x′，y′(T(x′，y′)-I(x+x′，y+y′))2 (1)
In the above formula (1), I (x + x ', y + y') represents a parameter of the acquired touch screen display image to be identified, which is, for example, an 8-bit integer or a 32-bit floating point number. And x and y represent pixel points of the touch screen display image to be identified. T (x ', y') represents a parameter of a predetermined template (e.g., a cursor template image). The predetermined template is smaller than the touch screen display image to be recognized and has the same data type. x ', y' represent pixel points of a predetermined template image. R (x, y) represents the matching result.
In some embodiments, the vehicle-mounted device may also calculate the matching degree through a correlation matching calculation or a standard correlation matching calculation by a multiplication operation between a predetermined template and a touch screen display image to be recognized.
In the above scheme, the method and the device can further identify whether the user terminal can be reversely controlled by the vehicle-mounted device via the USB connection mode when the user terminal cannot be reversely controlled by the vehicle-mounted device via the Bluetooth mode.
