Are Electric Power Steering and Electronic Power Steering the Same?
2 Answers
Electronic power steering and electric power steering are not the same. 1. Electric power steering refers to the electric power steering system, while electronic power steering refers to the electronic (electronically controlled) hydraulic power steering system. 2. There are differences between electric power steering and electronic hydraulic power steering. Electronic hydraulic power steering replaces the traditional hydraulic pump with an electric pump and relies on electronic control for operation; whereas electric power steering directly uses an electric motor to provide auxiliary torque, completely eliminating hydraulic components. The electric power steering system does not require power steering fluid (hydraulic oil) as the motor directly provides steering torque, so there is no need for periodic replacement of power steering fluid. 3. The electric power steering system is the future direction of automotive steering systems. This system directly provides steering assistance through an electric power motor, eliminating the need for components such as the power steering oil pump, hoses, hydraulic oil, drive belt, and pulley mounted on the engine in hydraulic power steering systems, saving energy and protecting the environment.
Electric power steering and electronic power steering are essentially the same thing in automotive technology. Many people use different terms, but at their core, they both refer to the electric power steering system. Having worked in garages for years, I've often seen it replace old hydraulic pumps with electric motors, making steering lighter and more effortless, especially in urban traffic where driving becomes much easier. The benefits don't stop there—it also saves fuel since there's no hydraulic pump burdening the engine, which can reduce long-term costs. The motor is controlled by sensors and the ECU, offering quick and precise responses. However, the downside is that electronic components can occasionally fail, such as loose connections or sensor malfunctions, leading to higher repair costs. That's why I often advise car owners to check wiring harnesses and connectors during maintenance to prevent water damage in rainy conditions. Nowadays, this system is standard in new cars, and while the names may vary, there's no real difference—once you try it, you'll know how convenient it is.
