What does power steering mean?

Power steering refers to the addition of external force to counteract steering resistance, allowing the driver to complete steering with less effort. Also known as power-assisted steering, it makes driving simpler and more comfortable, while also improving vehicle responsiveness and, to a certain extent, enhancing safety. There are three types of power steering systems commonly equipped in vehicles: mechanical hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems. The power steering pump, as the power source of the vehicle's steering system, is the heart of the steering system. The key function of power steering is to assist the driver in adjusting the vehicle's direction, reducing the effort required to turn the steering wheel.
Power steering is the system that makes turning the steering wheel feel less strenuous when you're driving. It makes parking or taking turns much easier, especially noticeable at low speeds. Having driven for decades myself, older cars without power steering required full-body effort to turn, while modern cars with power steering only need a light twist. This system mainly relies on a hydraulic pump or electric motor to assist—it automatically adds force when you turn the wheel. I recommend regularly checking if the power steering fluid is sufficient or if the electronic components are functioning properly, because if it fails, the steering will become very heavy, significantly compromising safe driving. Driving is a skill, and power steering indeed makes it much less physically demanding, allowing for easier focus on the road.
