The invention discloses an active/semi-active switchable electromagnetic shock absorber and a control method, and relates to the technical field of electromagnetic shock absorber design. When the driving mode is an energy-saving mode, the electromagnetic damper enters a semi-active working state, the optimal control current of the electromagnetic damper is calculated firstly, the motor current is converted into direct current through the three-phase rectifying circuit, then the buck-boost circuit is controlled to adjust the motor current, and the optimal ideal control current is tracked for damping. A part of vibration is converted into electric energy to be collected into a storage battery; when the driving mode is a comfortable mode, a pure active working state is entered, and a storage battery is used for actively controlling a motor through a three-phase inverter circuit; and when the driving mode is a comprehensive mode, entering a semi-active/active integrated working state, and performing autonomous switching of the working state according to whether the current can track the optimal ideal control current or not in the semi-active mode. According to the invention, the automobile can adapt to complex driving conditions, and the energy consumption is reduced while the vibration reduction performance is ensured.
