隨著技術革新傳統油壓式轉向控制器（Hydraulic Power Steering）車輛，逐漸會被電子轉向控制器（Electrical Power Steering）所取代。 在中國大陸的電子轉向控制器，在中國大陸每年需求數百萬台，但設計時通常未將車輛安全及車輛操控性擺在第一順位考量，而是將成本列為第一選項。由於全球各家一級車廠都將電子轉向控制部品列在重點開發事項中，而且國外所開發電子轉向控制以車輛安全及車輛操控性擺在第一順位考量，但其因關鍵技術不會外放，故在多方評估下，本文決定研發設計一套高效能電子轉向控制器（High Efficient Electrical Power Steering），著具有滿足車輛安全及車輛操控性與節省燃油之方向並進。 ;As the technique promoles, the traditional hydraulic steering controller (Hydraulic Power Steering) vehicles will be gradually steer controller (Electrical Power Steering) replaced. In mainland China is incrased, the demand of millions of electronical steering controller per year is increased, but the vehicle safety and vehicle maneuverability of design are usually not taken into consideration .The main focus is the cost. Since the design of electrical power steering controllers in the world is focused on the safety and maneuverability,the key techniqe would not be discovered. Therefore,a high efficient electrical power steering controller is designed and implemented in this thesis to meet the requirements of vehicle safety, vehicle maneuverability,and fuel saving.
