AI Technical Summary

Technical Problem

Existing methods for dynamic identification and classification of wirelessly charged vehicles are not very stable and are difficult to accurately identify and classify vehicle types.

Method used

A method combining hybrid electromagnetic induction unit and geomagnetic field induction unit is adopted. Induced resonant current is generated by capacitor plates and induction coils on the vehicle and roadside. Combined with a triaxial geomagnetic sensor to capture the geomagnetic disturbance signal of the vehicle, the data is analyzed by a host computer to identify the vehicle type.

Benefits of technology

It improves the reliability of wireless charging vehicle dynamic classification, effectively identifying four types of vehicles: small cars, SUVs, medium-sized trucks, and large buses, expanding the detection range and improving the open-domain coupling defects of traditional electromagnetic induction.
