Pros and Cons of Modern Cars Using Electric Power Steering

Modern cars often incorporate electric power steering (EPS) due to its numerous benefits. However, like any technological advancement, it also has some downsides that drivers should consider. In this article, we will explore both the advantages and disadvantages of using EPS in cars.

Advantages of Electric Power Steering

Electric power steering has several advantages over traditional hydraulic power steering (HPS). Some of the key benefits include:

Lighter and More Effort-Free Turning: EPS uses an electric motor to assist the steering, making it much lighter to use, even for larger vehicles. This is particularly advantageous during parking maneuvers where minimal effort is required to turn the wheel. Redundancy in Operation: Unlike HPS, which can stop functioning if the engine fails, EPS continues to operate even if the engine stops. This provides a safety enhancement for drivers. Space-Saving: EPS takes up less space under the hood compared to hydraulic systems. This allows for better interior and engine compartment organization and easier access to other components. No Fluid Leakage: There is no need to check or change oil, as EPS does not use hydraulic fluid. This eliminates the risk of leaks and associated maintenance. Compatibility with Hybrid and Electric Vehicles: EPS is particularly suitable for hybrid and electric cars, as it can be integrated more seamlessly with their more complex electrical systems, leading to lower spare parts costs and easier maintenance.

Speed Sensitivity

Another significant advantage of EPS is that it is speed-sensitive. The system adjusts the steering assist based on the vehicle's speed, providing a more precise and responsive driving experience.

Disadvantages of Electric Power Steering

While EPS has numerous advantages, it also has some drawbacks that drivers should be aware of:

Steering Feel: EPS, especially in lower-end models, can provide less feedback to the driver compared to hydraulic systems. This can affect the overall driving experience for driving purists who prefer a more mechanical sensation when steering. Complexity: While EPS is generally less complex in terms of parts, some components like the electric motor can be more prone to failure. If an issue arises, it may be more costly and difficult to repair. Weight and Size: Although EPS is lighter in comparison to hydraulic systems, it still requires an electric motor, which can add some weight and size to the steering column. However, the overall weight and size savings from the rest of the system far outweigh this.

Conclusion

In summary, electric power steering offers significant benefits such as lighter and more effort-free turning, redundancy in operation, space-saving, no fluid leakage, and compatibility with hybrid and electric cars. However, the reduced steering feel, complexity, and potential for weight and size increases should also be considered.
