The invention provides an intelligent tracking type dynamic wireless electric energy transmission system suitable for a high-speed driving electric vehicle. The intelligent tracking type dynamic wireless electric energy transmission system comprises an inverter power supply end, a ground transmitting end, a vehicle-mounted receiving end and a position detection end. The ground transmitting end is composed of a plurality of transmitting units, the transmitting units are connected to the same inverter power supply end through a change-over switch, and each transmitting unit comprises a plurality of transmitting ends connected in parallel. The position detection end is responsible for detecting the running position of the vehicle and controlling the on-off of the switch; and the vehicle-mounted receiving end and the ground transmitting end are both subjected to magnetic shielding and magnetic confinement by adopting a high-permeability magnetic material. The beneficial effects of the invention are that the parallel transmitting terminal realizes automatic following tuning based on the influence of a ferromagnetic material on equivalent electrical parameters and the comprehensive design of the resonant topology, can automatically follow the driving position of the electric vehicle and actively adjust the transmission power distribution of the parallel transmitting terminal; the intelligent tracking dynamic wireless power transmission suitable for the high-speed driving electric automobile is realized.
