And a localized voice control vehicle-mounted screen display module is also arranged on some high-end vehicle models, so that the voice control vehicle-mounted screen display can be realized.
However, the manual control disturbs the normal driving of the driver, distracts the driver, requires a plurality of manual operations for obtaining the display information, and is complicated in flow and inefficient. Approximately 6 million people die of a traffic accident each year, and more than 20 million people die of the traffic accident. The driving load is a main cause of various large traffic accidents, and the traditional driving operation process occupies factors such as the hearing and the vision of a driver and disperses the attention of the driver. In the localized voice control vehicle-mounted screen display module, the voice recognition module and the corpus occupy a large amount of memory space, and the requirements on the operation and space storage of the localized platform are high. Therefore, how to concentrate the attention of the driver in the driving process to ensure the safety of the driver, improve the accuracy and the recognition speed of voice recognition and reduce the operation requirement of a local control platform is the problem to be solved at present.

Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Fig. 1 is a block diagram of a system structure in an embodiment of the present invention:
in one example, the embedded system control platform 400 acts as an overall control unit that controls the sound pickup 100 to receive voice information of a user. After receiving the voice information of the user, the embedded system control platform 400 sends the voice information to the voice recognition cloud platform 300 for voice recognition. The voice recognition cloud platform 300 comprises a science and university communication flying cloud platform, a Baidu cloud platform and a Hua-Yun cloud platform, a corpus is stored on the voice recognition cloud platform 300, and the voice recognition cloud platform 300 returns character information obtained through recognition to the embedded system control platform 400 after combining data of the corpus and performing feature extraction, quantization and recognition on user voice information. The embedded system control platform 400 matches the returned text information with control commands stored in the command database 500 in advance, wherein the control commands include a vehicle speed reading and displaying command, a temperature reading and displaying command, a fuel consumption reading and displaying command and a navigation displaying command. After matching the control command, the embedded system control platform 400 controls the corresponding sensor 200 to acquire the corresponding vehicle condition information in real time, and reads the acquired real-time information of the corresponding sensor 200, where the sensor 200 includes: the vehicle speed sensor is used for monitoring the running speed of the vehicle in real time; the temperature sensor is used for measuring the temperature inside and outside the vehicle in real time; and the fuel consumption sensor is used for acquiring the residual fuel quantity of the vehicle in real time. The embedded system control platform 400 combines the control instruction matched with the voice information of the user to display the real-time vehicle condition information acquired by the corresponding sensor 200 on the vehicle-mounted screen and the player 600, and the voice broadcaster broadcasts the displayed information while the screen displays the information.
The voice recognition technology and the display screen control system are combined, the voice recognition technology is adopted, the voice information of a driver is monitored in real time, the voice is recognized through the voice recognition cloud platform 300, and the control instruction is obtained after the voice is matched through the instruction database 500. The embedded system control platform 400 acquires real-time data of the corresponding sensor 200 according to the control instruction, transmits the real-time data to the vehicle-mounted display screen, and displays and broadcasts the real-time data. According to the invention, on one hand, a method for manually operating and adjusting the display screen is abandoned, adverse effects caused by excessive manual operation of a driver in the driving process are overcome, and on the other hand, the voice recognition function is arranged on the Internet cloud platform, so that the operation requirement of the local control platform is reduced.
