The automotive steering system is mainly divided into four types: mechanical steering system, mechanical hydraulic power steering system, electro-hydraulic power steering system, and electric power steering system. The mechanical hydraulic power steering system provides assistance through a hydraulic pump, featuring a simple and reliable structure but relatively high energy consumption, and is commonly found in economy models. The electro-hydraulic power steering system adopts an electric pump and an electronic control unit, which can automatically adjust the assistance force according to vehicle speed and steering angle, balancing handling flexibility and high-speed stability, and is mostly used in mid-to-high-end models. The electric power steering system is directly assisted by an electric motor, achieving intelligent adjustment through sensors and an electronic control unit. It has advantages such as energy efficiency, environmental friendliness, and rapid response, and has become a mainstream configuration in modern vehicles, especially suitable for urban driving. Different steering systems have their own characteristics: mechanical systems are suitable for users pursuing a pure driving feel, hydraulic systems have advantages in reliability and cost, while electronic systems focus more on intelligence and energy efficiency. Consumers can choose according to their own needs.
