How Electric Power-Assisted Steering Works & Improves Your Driving Experience

How Electric Power-Assisted Steering Works

Unlike hydraulic power steering, which uses a belt-driven pump to provide steering assist, EPAS utilizes an electric motor mounted directly on the steering rack or column. A computer controls this motor and continuously monitors driver input and road conditions, allowing it to provide the optimal steering assist at any given moment.

The main components of an EPAS system include the steering rack, electric motor, torque sensor, and electronic control unit. As the driver turns the steering wheel, the torque sensor measures the input force and sends a signal to the control unit. The control unit then adjusts the amount of power the electric motor supplies to lighten the steering effort.

Benefits of Electric Power-Assisted Steering

One of the key advantages of EPAS is improved fuel efficiency. Since the system only provides assist when needed, it does not constantly draw power from the engine like traditional hydraulic setups. This can result in a 3-4% improvement in fuel economy. If you want to save money at the pump near Downers Grove, an EPAS-equipped vehicle is worth considering.

EPAS also offers more precise steering control and enhanced driver feedback compared to hydraulic systems. The electronic control unit can adjust steering assist based on vehicle speed, providing a firmer feel at highway speeds and lighter effort when parking or maneuvering at low speeds. Additionally, EPAS enables advanced driver assist features like lane keep assist and park assist that can help make driving safer and less stressful.
