The invention relates to a dual-energy-source electric hydraulic power steering system, a control method and an electric coach. A dual-energy-source EHPS system comprises a high-voltage power source, a high-voltage steering controller and a steering motor. The high-voltage power source is in drive connection with the steering motor through the high-voltage steering controller. The dual-energy-source EHPS system further comprises an emergency steering controller in drive connection with the steering motor. The high-voltage power source and the high-voltage steering controller serve as main energy parts, an emergency power source and the emergency steering controller serve as auxiliary energy parts, when the main energy parts break down, the auxiliary energy parts are started and used as EHPS emergency energy, it is guaranteed that the whole coach has the steering assistance, and therefore the dangerous situation that no steering assistance of the whole vehicle is available under the inertia or downhill condition when a main steering assistance part suddenly breaks down or fails is avoided.
