Abstract: In order to solve the problems of easy leaking and structural complexity on steering system of homemade electric forklift due to general use of hydraulic power steering system, electric power steering(EPS) technology was introduced into the design of steering system on electric forklift. After the analysis of the components of EPS typical system, the principal of threecontrol methods in EPS system was established. A method was presented to the application of EPS methods on forklift, and it was tested on the model machine. The experimental results show that the EPS system can replace the traditional hydraulic steering system for its smooth operation, good reliability and excellent steering performance.
