The invention discloses a wireless charging system, a control method and an automobile wireless charging device. The system comprises a PFC circuit, an inverter circuit, a primary side resonance network and an infrastructure sampling control circuit which are located on an infrastructure side, a secondary side resonance network, a controllable rectification adjusting circuit and a vehicle-mounteddetection control circuit which are located on the vehicle-mounted side. The control method comprises steps of adjusting the working parameters of the vehicle-mounted side controllable rectification adjustment circuit according to the detected resonance parameters of the primary side resonance network and the secondary side resonance network or the related quantity capable of reflecting the resonance state of the system, so as to enable the primary side resonance network and the secondary side resonance network to be in resonance matching; detecting the voltage and/or current output by the controllable rectification adjusting circuit, and generating a corresponding detection signal and/or control instruction. The infrastructure sampling control circuit is in communication connection with the vehicle-mounted detection control circuit, and controls and adjusts the output current and/or output voltage of the PFC circuit and the inverter circuit or the phase shift angle of the inverter circuit according to the detection signal or instruction output by the vehicle-mounted detection control circuit, so that the output meets the requirements.
