A Quick Guide to Understanding Electronic Power Steering

Analysts predict the Global Electric Power Steering market will rise significantly between 2022 and 2028. In 2021, the market already presented signs of shifting.

Why is this? Electronic power steering (EPS) is transforming the way vehicles help drivers. This technology offers significant advantages over other steering systems. And because of these advantages, more automated cars will use them.

Keep reading to learn what electronic power steering is, how it works, and its advantages.

What Is Electronic Power Steering?

Electronic power steering, or motor-driven power steering (MDPS), uses electric motors to help you steer and control your vehicle. Most modern vehicles will use EPS. Because of this feature, EPS serves as a critical feature for automated driving and cars.

Sensors within your motor will detect your vehicle’s torque and position. With this information, your EPS can tailor how it helps you with driving. The MDPS can help with steering, handling, and variable-damping suspension depending on the driving conditions.

Some vehicles with motor-driven power steering include park assist and lane assist. The former helps you park your vehicle without bumping into other cars. The latter will help you pick the best time to switch lanes.

How Does EPS Work? Electronic Power Steering Explained

To understand how this technology works, you’ll need to know what makes an EPS. Several parts that create these systems include:

  • Torque sensor: converts your car’s mechanical torque into an electrical signal
  • Reduction gear: transmission device that connects the EPS motor to your vehicle
  • Electric motor: controls your vehicle’s steering
  • Module: collects information regarding driving conditions and sends it to the driver in the form of recommendations

Some electronic power steering systems will use high-performance plastic gears.

The module will collect information from areas throughout your vehicle—like your traction control. It will then send how much your vehicle should turn to the electric motor.

Advantages of EPS

Unlike hydraulic systems, which require fuel to run, MDPS doesn’t require any. Because of this design, your vehicle will use less gas, which will improve your fuel economy. Thus, you’ll save money and have a vehicle that’s a bit better for the environment.

Since these systems don’t require fuel, they’re easier for car owners to maintain. First off, you’ll never deal with links. With one of these systems, you won’t have to worry about topping off power steering fluid.

Because of the built-in modules and sensors, electronic power steering will provide more accurate steering compared to hydraulic systems.

Then there’s having an overall lighter and smaller system. EPS doesn’t use pulleys, belts, drive belts, pumps, and hoses, unlike hydraulic power steering.

Electronic Power Steering Offers Several Benefits

Electronic power steering triumphs over hydraulic steering systems by using electric motors to guide your vehicle. They’ll reduce weight over your car’s front axle and add more adjustability to your driving style.
