Turning the wheels of your car has gotten more complicated in a bid to help save the world: Steering System Deep Dive - The Drive Digest

Today in the revamped newsletter, we bring you the best automotive engineering news to your inbox every week with insights into technology, business and macro trends.

Have you ever found yourself curious about what precisely guides your vehicle as you navigate winding motorways or manoeuvre through congested city streets? Well, today we're strapping in for an exciting exploration into the intricate, fascinating world of different steering systems. We'll delve into the nitty-gritty of hydraulic, electro-hydraulic, and electric power steering systems that are commonly used in both cars and lorries. On the surface, it might not seem like the most thrilling topic, but we promise, it's much more captivating than it initially appears.

The Hydraulic Dilemma

Our journey begins with a deep dive into the workings of the hydraulic steering system. This technology, like a vintage vinyl record player, has been a tried-and-true companion in our vehicles for countless decades. However, just as we've transitioned from vinyl records to digital music, it's high time our steering systems also took a similar leap forward.

The hydraulic system operates by utilising hydraulic pressure to aid in your steering. However, it's a notorious fuel guzzler, likened to attempting to run a marathon powered solely by fast food. While it might technically get you to the finish line, it's hardly an efficient or sustainable method. The same is true for hydraulic steering. It consumes far more energy than is necessary, contributing significantly to the vehicular emissions that are damaging our environment.

Additionally, accuracy is another significant challenge for hydraulic systems. In an era where advanced driver-assistance systems (ADAS) are becoming increasingly commonplace, our steering systems need to offer the precision of a master craftsman's tools. However, the hydraulic system often falls short, delivering accuracy that's more akin to a blunt tool than a finely honed scalpel.

The Need for Change?

The detrimental impact of climate change is becoming increasingly evident, and it's no secret that the transportation sector plays a substantial role in contributing to this global issue. As we collectively strive to minimise our carbon footprints, it prompts us to question whether our current steering systems could do better in terms of energy consumption.

Safety, too, is a vital consideration in the discussion around steering systems. A vehicle's steering system should be a reliable co-pilot, guiding us effortlessly through our journeys and ensuring our safety on the roads. Is your current system up to the task?

Cars vs Lorries: A Tale of Two Steering Systems

Before we dive into the potential solutions to these challenges, let's take a quick detour to understand the differences between steering systems in cars and lorries. Cars, being smaller and lighter, have traditionally used hydraulic or electro-hydraulic systems. Lorries, on the other hand, due to their larger size and heavier load, have often relied on more robust hydraulic systems that can handle the extra weight.

However, as steering technology evolves, we're beginning to see a shift in both these vehicles types. More and more cars and lorries are moving towards more energy-efficient and precise electric power steering systems.

The Trailblazers

Now, brace yourselves, because the world of steering systems is about to get a whole lot more exciting. The electro-hydraulic and electric power steering systems are the new kids on the block, poised to revolutionise your driving experience.

Electro-Hydraulic Power Steering Systems

The electro-hydraulic power steering system (EHPS) represents the perfect blend of tradition and innovation. It's akin to a symphony where classical stringed instruments harmonise seamlessly with modern synth beats. This system cleverly uses an electric motor to pump the hydraulic fluid, but only when necessary. This smart energy conservation strategy leads to reduced emissions and a more eco-friendly driving experience.

Moreover, when it comes to safety, the EHPS is a real game-changer. It offers speed-sensitive assistance, adjusting the level of steering support based on the vehicle's speed. This feature ensures optimal control and a driving experience that's as smooth as gliding on ice.

Electric Power Steering Systems

Next, let's delve into the electric power steering system (EPS), the ground-breaking newcomer that's causing a stir in the automotive industry. The EPS employs an electric motor that directly steers the vehicle, doing away with the need for hydraulic fluid altogether.

EPS is the undisputed eco-hero of steering systems. Its electric motor only springs into action when steering assistance is required, resulting in a significant reduction in emissions.

But the benefits of EPS don't end at environmental friendliness. The EPS system can also be customised to include a variety of safety features like lane-keeping assist and automatic emergency steering. These features not only enhance driving safety but also pave the way for advanced self-driving systems.

As we navigate towards a future that is greener and safer, these innovative steering technologies are our guiding compass. By gaining a deeper understanding of these systems, we can make informed choices about our vehicles and promote technology that benefits us all.

Thank you for embarking on this journey with us. We hope you found it as fascinating as we did. Stay tuned for more insights into the dynamic, captivating, and ever-evolving world of vehicle technology.
