Research of Magnetic Field Navigation Intelligent Vehicle System Based on Difference Algorithm

To implement intelligent vehicle control system based on magnetic field detection, automation navigation scheme based on difference algorithm is proposed. The feature of magnetic field of the road is analyzed, and layout method of sensors is proposed, and signals of magnetic field sensors are gathered and filtered, and road control strategy based on difference algorithm is proposed, and steering gear is used to implement cornering of intelligent vehicle, and position PID algorithm is used to implement speed control of intelligent vehicle. The experiment result shows that intelligent vehicle using this scheme can work steadily at high speed, and has higher practicability and is worth to be propagated in many fields.
