The invention discloses a piezoelectric electromagnetic composite energy feedback active suspension which comprises an active hydraulic suspension body and an integrated control loop. The hydraulic suspension body comprises a connecting bolt, a rubber main spring, a metal shell, a metal base, an upper inertia channel body, a lower inertia channel body, a decoupling film, a rubber bottom film, a throttling disc, an electromagnetic actuator, an electromagnetic shielding net and an energy feedback system. The energy feedback system comprises a first piezoelectric energy feedback system, a secondpiezoelectric energy feedback system and an electromagnetic energy feedback system. The first piezoelectric energy feedback mechanism is composed of a compression nut, an upper-layer composite material piezoelectric patch, a substrate, a lower-layer composite material piezoelectric patch, a connecting bolt and a protective shell and is of a bicrystal cantilever type piezoelectric energy feedback structure. The second piezoelectric energy feedback mechanism comprises a composite material piezoelectric cylinder and a force transmission pressing block; the electromagnetic energy feedback mechanism comprises a permanent magnet, a silicon steel sheet, an excitation coil and a sealing top cover. The invention further discloses a control method of the piezoelectric- electromagnetic composite energy feedback active suspension.
