In the following description, numerous specific details are set forth in order to provide a thorough understanding of, and enabling description for, those skilled in the art. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. Furthermore, it should be understood that the invention is not limited to the specific embodiments described. Rather, any combination of the features and elements described below is contemplated as carrying out the invention, whether or not they relate to different embodiments. Thus, the following aspects, features, embodiments and advantages are merely illustrative and are not considered elements or limitations of the claims except where explicitly recited in a claim.
Referring now to fig. 1, a voice control method for enhancing information security based on a cloud device according to an embodiment of the present invention is shown. As shown in fig. 1, the method includes:
and S101, the cloud device distributes corresponding virtual safety controls for different voiceprints, and the different virtual safety controls have different voice control authorities so as to control vehicle-mounted devices in target vehicles adapting to the authorities through voice.
Step S102, aiming at a voice instruction of a user, the cloud end equipment confirms a corresponding virtual security control according to voiceprint information obtained from the voice instruction, further confirms a corresponding voice control authority and generates a control command which accords with the voice control authority.
Specifically, a voice instruction of a user is obtained through a mobile terminal carried by the user and sent to a cloud device, the cloud device sends a generated control command to the mobile terminal, and the mobile terminal uses the control command to operate corresponding vehicle-mounted equipment in a target vehicle through near field communication. The mobile terminal and the vehicle may be communicatively connected via bluetooth (e.g., BLE (bluetooth low Energy)) or UWB (Ultra wide band).
By means of the method, the cloud device can allocate corresponding virtual safety controls to voiceprints of different users, so that different users can only operate vehicle-mounted devices allowed by the corresponding virtual safety controls through voice instructions, specific users cannot obtain voice control permission of the vehicle-mounted devices which may affect safe driving of the vehicle, and potential safety hazards are avoided. For example, the cloud-based device may assign different control permissions to adult passengers and child passengers as instructed by the driver of the vehicle. The control authority assigned to the child passenger can enable the child passenger to control only the sound and the air conditioner but not the vehicle door and the vehicle window, so that potential safety hazards are avoided.
Optionally, each mobile terminal can only recognize and send a voice instruction of a user carrying the mobile terminal, thereby making the control process safer.
Optionally, the cloud device may synchronize the virtual security control to the target vehicle. And the target vehicle carries out authority verification on the control command provided by the mobile terminal according to the virtual safety control, and if the authentication is passed, the mobile terminal is allowed to operate corresponding vehicle-mounted equipment in the target vehicle by using the control command, so that the information safety of the voice control process is enhanced.

In another optional embodiment of the present invention, it may be set that the vehicle-mounted device of the target vehicle can be operated using the control command only after the mobile terminal carried by the user establishes the near field communication connection with the target vehicle, so that the user who is too far away from the vehicle is prevented from operating the vehicle-mounted device, and the potential safety hazard is avoided.
Based on the method provided by the embodiment in fig. 1, fig. 2 shows an application scenario of a voice control method for enhancing information security based on a cloud device according to another embodiment of the present invention. In the application scenario shown in fig. 2, the driver of the vehicle assigns different voice control authorities to different passengers, so that different passengers can only operate the vehicle-mounted devices allowed by the corresponding virtual safety controls through voice commands. As shown in fig. 2, in this application scenario:
each user (including the driver and passenger) associates its voiceprint to the user's mobile terminal so that each mobile terminal can only recognize and transmit voice instructions of the user carrying the mobile terminal. The cloud device distributes corresponding virtual safety controls to voiceprints of different passengers according to instructions of a driver, and the different virtual safety controls have different voice control authorities, so that the different passengers can obtain authorities of vehicle-mounted devices allowed by the corresponding virtual safety controls operated through voice instructions. The cloud device stores the virtual security controls and synchronizes the virtual security controls to the vehicle.
After the cloud device receives a voice instruction sent by a passenger through the mobile terminal, the corresponding virtual security control is confirmed according to voiceprint information in the voice instruction, then the corresponding voice control authority is confirmed, a control command conforming to the voice control authority is generated, and the control command is sent to the mobile terminal.
As shown in fig. 2, the cloud device can implement user information management, voice recognition, and human linguistics functions. The cloud device can distribute virtual security controls to different voiceprints through a user information management function, and the corresponding virtual security controls are matched according to voiceprint information in the voice command. The cloud device can generate the control command through any one of the following three ways through voice recognition and human linguistic functions:
1. the recognition of the voice command is completely finished by the mobile terminal, and the cloud equipment generates a control command according to the recognition result of the mobile terminal;
2. the recognition of the voice instruction is partially completed by the mobile terminal (for example, the mobile terminal can perform simple and standardized voice recognition), and the cloud device completes the recognition of the voice instruction and generates a control command on the basis of the recognition; and
3. the mobile terminal only carries out voice pickup, and the recognition of the voice instruction is completely finished by the cloud equipment and generates a control command.
After receiving the control command from the cloud device, the mobile terminal sends the control command to the vehicle through near field communication (such as bluetooth or UWB).
After receiving the control command, the HPC (High Performance Computing) module of the vehicle performs authority verification on the control command, and if the control command is authenticated, allows the mobile terminal to manipulate the corresponding in-vehicle device in the target vehicle using the control command. The in-vehicle equipment may include in-vehicle lights, windows, sunroofs, doors, trunk doors, wipers, in-vehicle power supplies, entertainment systems, emergency call devices, air conditioners, and the like.
The solution of the invention is applicable not only to the current automotive architecture, but also to the new automotive architecture under development (domain controller-based, HPC-based).
Although the present invention has been described with reference to the preferred embodiments, it is not to be limited thereto. Various changes and modifications within the spirit and scope of the present invention will become apparent to those skilled in the art from this disclosure, and it is intended that the scope of the present invention be defined by the appended claims.
