| 摘要 |
The invention relates to a device and a method for assisting the robotic navigation of a vehicle in a noisy environment, where the device comprises an arrangement of microphones provided in the vehicle for capturing both the internal and external sound of said vehicle; and an analog-to-digital signal processor that filters and conditions the signals obtained from the arrangement of microphones, which are restricted to a hearing range of the human being, between 300 and 20,000 Hz, rejecting frequencies below 300 Hz and over 20,000 Hz, by means of programable band-pass filters. Furthermore, the processor processes and classifies the signals, detecting the environments according to the sound thereof, by means of neuronal networks of the feed-forward type; and generates restrictions on the maximum and minimum speed limits of the vehicle, both linear and angular, for the control of the vehicle. |
