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.

    本发明公开了一种电动堆垛车电助力转向系统,包括:操控手柄、传动机构、助力转向器、驱动单元和驱动轮,操控手柄通过传动机构与助力转向器的输入端连接,助力转向器的输出端通过驱动连接座与驱动单元连接,驱动单元用于控制驱动轮行走,输入端和输出端通过机械传动装置连接,操控手柄用于通过传动机构带动输入端转动,当助力转向器通电时,增大输出端的扭矩,当助力转向器断电时,通过机械传动装置带动输出轴转动,以带动驱动单元转动,进而带动驱动轮转向。本发明还公开了一种电动堆垛车电助力转向控制方法,相对于纯人力转向,可降低工作强度,提高操作舒适性;相对于纯电助力转向结构,结构简单、成本低,而且具有更高的转向可靠性。
