It is not enough to rely on the hardware anti-interference technology alone, so it is necessary to use the intelligent control software anti-interference control technology to overcome the interference of some hardware effectively. In the toy car in the single chip microcomputer intelligent control system, if the toy car can correct choice using intelligent control software anti-jamming technology, and intelligent control of the hardware anti-interference control measures of intelligent control and anti-interference of defence is undoubtedly to control will greatly improve the system reliability and working reliability of the system. The anti-jamming technology of intelligent control software used in toy cars is mainly digital filtering control technology, switching control software anti-jamming control technology, command software redundancy technology, software trap anti-jamming technology and so on.
