Why Electric Power Steering Is Becoming the Driving Force Behind Modern Vehicles

We're in the midst of one of the greatest changes in the history of the automotive industry. Today, cars are getting more and more advanced; from electric vehicles and autonomous driving, to new safety features.

Amidst all the headlines surrounding the electric car revolution and future autonomous driving capabilities, there is a discreet yet critically important technology that is present in almost every new vehicle we see on the road: Electric Power Steering (EPS).

Most car owners never even consider their steering system but its importance cannot be understated, especially for driver safety, passenger comfort, fuel efficiency, and vehicle handling. As manufacturers push forward towards a future of electric mobility and "intelligent" cars, electric power steering is quickly becoming the default steering technology worldwide.

The global market for Electric Power Steering systems is estimated to reach approximately $31 billion in 2025 and will grow to an estimated $46.2 billion by 2034, a reflection of its increasing prominence in passenger and commercial vehicles, as well as the growth in electric cars and future autonomous driving technologies.

What is Electric Power Steering?

In a traditional, hydraulically powered steering system, engineers had to employ a number of parts-pumps, hoses, and hydraulic fluid-all contributing to the act of steering assistance. All these components, however, consume energy from the engine and require regular maintenance.

Electric Power Steering, however, uses an electric motor along with sophisticated sensors and control units to achieve a similar outcome.

Here, an electric motor, controlled by the cars' internal computer, provides steering assistance in response to the driving situation and how the driver is manipulating the steering wheel.

The result is a more precise, more efficient and adaptable steering experience that no longer has to rely on an engine-powered hydraulic pump to get the wheels turning.

It also makes vehicles lighter, leading to more efficient cars.

Why Automakers are Leaving Hydraulic Steering

The days of the hydraulic power steering system dominating the automotive market are quickly drawing to a close as consumer priorities have drastically shifted towards the following:

* Higher fuel efficiency

* Safer vehicles

* Easier maintenance requirements

* The ability to integrate vehicle systems

* Environmental friendliness

The move towards Electric Power Steering directly addresses these requirements.

Since electric power steering only requires power when the car is actually being steered and assisting, it uses far less energy than the always-on systems required by hydraulic steering, therefore increasing fuel efficiency while simultaneously decreasing emissions.

Governments all over the world are imposing stricter regulations on vehicle emissions and Electric Power Steering provides manufacturers with a method to combat this and comply with them.

The Electric Car Boom is Fueling Demand

One of the main drivers of this growth is the rapid development of electric and hybrid vehicles.

In designing electric cars, manufacturers focus on maximizing energy efficiency at every stage. Each and every component of an electric car is considered in terms of its power consumption, and it was found that hydraulic steering systems require components that are far too energy-intensive to be integrated into electric vehicles.

Electric power steering, however, does not necessitate such components, fitting perfectly into electric vehicle designs.

As the market for electric vehicles continues to grow exponentially, demand for Electric Power Steering systems will only continue to rise, making them a necessity rather than a choice.

The Link Between Electric Power Steering and ADAS

New vehicles are becoming less like cars and more like machines; they are able to think on their own, anticipate the needs of the driver in real time, and even take action based on these estimations. Such features are known as Advanced Driver-Assistance Systems (ADAS) and are often integral parts of driverless car technology.

These features can include things like:

* Lane Keeping Assist

* Adaptive Cruise Control

* Automated Parking Systems

* Emergency Steering Assistance

* Collision Avoidance Systems

Without a precise steering mechanism, these ADAS systems will have no means of fulfilling their objectives. In fact, most Advanced Driver-Assistance Systems would not even be possible without the fine control that is required, which is why Electric Power Steering systems are becoming a staple in cars utilizing any of these advanced driver-assistance technologies.

As the world inch closer to a future where vehicles can drive themselves, steering systems that are smart and adaptive like Electric Power Steering will become a key feature of all cars.

Drivers Love Electric Power Steering

It's not just manufacturers and governments that are noticing the change in steering technology, the everyday consumer driving a vehicle equipped with an Electric Power Steering system is directly benefiting.

It gives drivers a smoother, lighter steering feel in the city or when parking and maneuvering at slow speeds, and provides increased firmness for stable and control at higher speeds, giving the driver the "best of both worlds."

Other benefits of Electric Power Steering that the driver notices:

* Reduced steering effort can decrease driver fatigue

* Enhanced handling and driving dynamics

* Better road feel feedback to the driver

* Reduced maintenance requirements

* Increased reliability

As drivers begin to learn and appreciate these differences between traditional and electric power steering, demand for Electric Power Steering equipped cars will only continue to surge.

The Rise of Smart Steering Technologies

Electric Power Steering systems are no longer simply designed to enhance the driver's ability to steer. The world is witnessing the rise of a variety of next generation steering technologies which are turning steering systems into "intelligent" platforms within the vehicle.

One such development to look forward to is "Steer-by-Wire" systems. In a steer-by-wire system, there is no physical linkage between the steering wheel and the wheels themselves and the steering input is sent electronically from the wheel to the cars actuators.

This has a multitude of benefits, including:

* Design flexibility

* Increased vehicle safety

* Faster response times

* Improved automated driving features

It is largely expected that this area of Electric Power Steering will experience significant growth over the next few years as we approach a fully automated driving experience.
