The invention discloses an energy and signal parallel wireless transmission system for an electric automobile and a control method, an energy transmitting end is provided with a composite high-frequency carrier module, an electric energy carrier module and a comparison circuit, and the composite high-frequency carrier module generates a composite high-frequency carrier signal according to a signal needing to be transmitted by a primary side; the composite high-frequency carrier signal and the electric energy carrier signal are compared through a comparison circuit to generate a PWM signal to drive a switching tube in the high-frequency inverter circuit to work, and the energy receiving end is further provided with a secondary separation network, a secondary rectification filter circuit and a signal demodulation circuit. The secondary separation network separates the energy and the signal picked up by the receiving coil, and the signal part realizes signal demodulation through a signal demodulation circuit; and the energy part supplies power to a vehicle-mounted battery after being processed by the secondary side rectifying and filtering circuit. The system has the advantages that synchronous transmission of electric energy and signals is achieved, cross coupling is avoided, and the efficiency of the system and the flexibility of application are improved.
