The invention relates to the field of automobile steering, in particular to an electro-hydraulic power steering system and a control method.The system is characterized in that the first connecting end of a first driving assembly is connected to a first oil way, the second connecting end of the first driving assembly is connected to a second oil way, and the first connecting end of a second driving assembly is connected to the first oil way; the second connecting end of the second driving assembly is connected to the second oil way, an oil port of the oil tank is sealed, the inlet end of the first controllable valve is connected to the first oil way, the outlet end of the first controllable valve is communicated with the oil tank, the inlet end of the second controllable valve is connected to the second oil way, and the outlet end of the second controllable valve is communicated with the oil tank. The first oil way is connected with the first input end of the hydraulic circulating ball steering gear, and the second oil way is connected with the second input end of the hydraulic circulating ball steering gear. The device further comprises a controller, and the first driving assembly and the second driving assembly are both connected to the controller. The device has the effects of simplifying the structure and reducing the energy consumption.
