What is Electric Power Steering?
2 Answers
Electric Power Steering is a power steering system that directly relies on an electric motor to provide auxiliary torque. The Electric Power Steering system represents the developmental direction of automotive steering systems. EPS directly supplies steering assistance through an electric power unit, eliminating the need for components such as the power steering pump, hoses, hydraulic fluid, drive belt, and engine-mounted pulley required by hydraulic power steering systems. This not only saves energy but also protects the environment. In the evolution of automobiles, steering systems have gone through four developmental stages: starting with mechanical steering systems, progressing to hydraulic power steering systems, followed by the emergence of electro-hydraulic power steering systems, and finally the electric power steering system.
I've experienced electric power steering many times - it makes driving incredibly effortless. When turning the wheel normally, it feels like someone's helping you apply force. No need to wrestle with the wheel, especially during parking or traffic jams where just a light touch does the trick. The old hydraulic systems weren't this friendly - they required brute strength and left your wrists sore after long drives. EPS uses an electric motor to assist steering, only activating when needed, which saves significant fuel costs. My car's smart system even makes minor steering corrections during lane departure warnings, maintaining stability even in rain. Maintenance is virtually hassle-free with no oil leakage concerns. The only thing to watch for is occasional sensor or circuit glitches that may temporarily increase steering weight, easily prevented through regular checkups.
