What is the EPS system in cars?
2 Answers
Car EPS system is an electronically controlled power steering system that can reduce steering force at low speeds to improve the maneuverability of the steering system; at high speeds, it can appropriately increase steering force to enhance handling stability. This system directly provides steering assistance through an electric power motor, eliminating the need for components such as power steering oil pumps, hoses, hydraulic fluid, drive belts, and pulleys mounted on the engine, which not only saves energy but also protects the environment. The main structure of the EPS system consists of a steering sensor device, vehicle speed sensor, power-assisted mechanical device, steering assist motor, and microcomputer control unit.
Actually, the EPS system in my car is the electric power steering system, which uses an electric motor instead of the old-fashioned hydraulic pump to assist with steering. Sensors detect the speed and angle of my steering wheel rotation, and then the computer controls the motor to provide just the right amount of force. The biggest advantage is fuel efficiency, since the motor only works when steering is needed, unlike the hydraulic pump that runs continuously. Plus, it's super considerate—at higher speeds, the steering assistance is heavier for stable highway driving, while at low speeds or when parking, the assistance is lighter, making it easy to handle with just one hand. I've noticed that most modern cars are equipped with this system now, and the failure rate is much lower. If there is an issue, it's also easier to diagnose. Overall, steering becomes smoother and smarter, enhancing both driving pleasure and safety.
