The invention discloses an electric power steering system of an electric piling car, which comprises a control handle, a transmission mechanism, a power steering gear, a driving unit and a driving wheel, the control handle is connected with the input end of the power steering gear through the transmission mechanism, and the output end of the power steering gear is connected with the driving unit through a driving connecting seat; the driving unit is used for controlling the driving wheels to walk, the input end and the output end are connected through a mechanical transmission device, the control handle is used for driving the input end to rotate through the transmission mechanism, when the power-assisted steering gear is powered on, the torque of the output end is increased, and when the power-assisted steering gear is powered off, the mechanical transmission device drives the output shaft to rotate so as to drive the driving unit to rotate. And the driving wheels are further driven to steer. The invention further discloses an electric power steering control method of the electric piling car, and compared with pure manual steering, the working intensity can be reduced, and the operation comfort can be improved; compared with a pure electric power-assisted steering structure, the electric power-assisted steering system is simple in structure, low in cost and higher in steering reliability.
