The invention relates to the technical field of engineering vehicles, and discloses an electric emergency steering system, a control method and an engineering vehicle. The electric emergency steering system comprises a power-assisted steering module, a power supply module, a signal detection module and a control module. The power-assisted steering module comprises an electric steering gear box and an electric power-assisted cylinder; the power supply module comprises a generator, an electric emergency brake and an emergency energy storage power supply, the electric emergency brake is electrically connected with the electric steering gear, the power supply end of the generator and the power supply end of the emergency energy storage power supply, and the emergency energy storage power supply is electrically connected with the generator; and the control module is configured to control the electric emergency brake to be switched to the emergency energy storage power supply for power supply when the working signal of the engine detected by the signal detection module is an abnormal stop signal, the working signal of the generator is an abnormal stop signal and the pressure of the vertical oil cylinder is lower than a preset pressure value. The electric emergency steering system is good in stability, simple in layout, small in occupied space, free of energy waste and high in adaptability.
