The invention discloses an electro-hydraulic steering device and method with a power-losing emergency function. The electro-hydraulic steering device comprises a hydraulic power source, an electromagnetic reversing valve, an electromagnetic ball valve, a hydraulic control one-way valve, an energy accumulator, an oil tank and a hydraulic cylinder. The hydraulic power source comprises a motor and a two-way hydraulic pump, the motor is connected with the two-way hydraulic pump, and the motor is used for driving the two-way hydraulic pump; the electromagnetic reversing valve is used for switching between an oil supply loop of the hydraulic cylinder and an oil charging loop of the energy accumulator, the electromagnetic ball valve is arranged between the energy accumulator and the hydraulic control one-way valve, the energy accumulator is adopted as standby energy for power-loss emergency steering, the influence of power failure, cable burning and the like is avoided, and the power-loss emergency steering is achieved. And the method has relatively high environmental adaptability.
