Abstract: | In order to further improve the automatic cruise smart car's speed, in the image acquisition part, we raise the analog CCD camera, reduce its angle of depression, and build a high-speed AD converter circuit outside the microcontroller.In the driving part, use the H-bridge driver circuit to drive the the smart car forward and brake, combined with speed encoder to obtain the real-time speed, and control it with PD algorithm. In the turning parts, improve servo mounting for vertical, and heighten its position. Conclusions prove that the smart car get a greater foresight and a sensitive turning response. It can operate quickly and stably. |
