What does EPS in cars refer to?
3 Answers
EPS stands for Electronic Power Steering. Below is relevant information about EPS: 1. It uses the power generated by an electric motor to assist the driver in steering. Although the structural components may vary between different vehicles, they are generally similar, typically consisting of a torque sensor, electronic control unit, motor, reducer, mechanical steering gear, and battery power source. 2. The electric power steering system directly provides steering assistance, eliminating the need for components like the power steering pump, hoses, hydraulic fluid, belts, and pulleys mounted on the engine required in hydraulic power steering systems. This not only saves energy but also protects the environment. Additionally, it features easy adjustment, flexible assembly, and the ability to provide steering assistance under various conditions. 3. Vehicles equipped with EPS have very light and easy-to-operate steering wheels, offering excellent handling. It's important to note that EPS is different from ESP (Electronic Stability Program), as EPS is one of the functions of ESP.
I've been driving for twenty years and what annoys me the most is hydraulic power steering—that thing is as heavy as lifting bricks! EPS stands for Electric Power Steering, and it's basically installed in all new cars nowadays. The biggest advantage is that the steering wheel becomes as light as a toy, especially when reversing or parking—you can turn it with just one hand. The principle is that there's an electronic sensor under the steering column; when you turn the wheel, the motor secretly helps you with the effort. At high speeds, the steering wheel even becomes heavier on its own, and it won’t wobble when hitting a puddle. But a word of caution: this thing is most afraid of water-damaged cars—repairing it could cost you half a Wuling Hongguang.
Last year, while test-driving a new energy vehicle with my kids, I noticed a detail: the steering wheel was unbelievably light. The salesperson said it's called EPS, two generations more advanced than the old hydraulic steering. Simply put, it replaces the hydraulic pump with an electric motor, and the onboard computer automatically adjusts the steering effort based on speed. Making a U-turn at low speed feels like twisting a bottle cap, while overtaking at high speed is rock solid. Most importantly, there's no worry about steering fluid leaks, and one less warning light on the dashboard. But since it's electronic, never blast the steering column directly with a high-pressure car wash spray. As a mom of two, I give this back-saving design full marks.
