Electric vs Hydraulic Power Steering

If you’re buying a new car, you’ll likely be using a vehicle with electric power steering, compared to an older car, which would presumably have hydraulic power steering. But which power steering system is better? In this article, we’ll review the various power steering systems and their respective benefits to determine which one is superior.  Electric power steering systems are a more recent advancement in the automotive industry, gradually replacing traditional hydraulic power steering systems with superior electronic components.

What Is Power Steering?

Power steering is any type of steering system that assists the driver with turning the wheels. If you’ve ever driven a car with manual steering or your power steering has failed, you know how hard it can be to turn the wheel with manual force alone. Power steering eliminates that worry and makes modern vehicles easier to control and more comfortable, making power steering vital for any vehicle.

How Does Hydraulic Power Steering Work?

Hydraulic power steering has been around for decades. The system helps turn the car’s wheels by utilizing the system’s pump, a cylinder, and a set of valves to control hydraulic fluid through them. The pump supplies pressure and is driven by a belt that connects to the engine. Tying the pump speed to the engine speed causes your wheels to turn more slowly at low speeds, while the vehicle will be more responsive at high speeds. The control valves return some pressurized hydraulic fluid to the reservoir to prevent a failure. Maintaining responsibility while ensuring that the steering ratio remains consistent. The cylinder applies force directly to the steering rack and rotates the tires when you turn the steering wheel.

Common Hydraulic Power Steering Issues

• Hydraulic oil leakage
• Hydraulic pump failure
• Steering valve failure
• Hydraulic line blockage
• Hydraulic cylinder failure

How Does Electric Power Steering Work?

Electric power steering has been widely popular since the 1990s and has been a favorite ever since. Electric power steering creates consistent performance under different driving conditions. An electric power steering system relies on an electric motor attached to the steering system. It uses a system of sensors to communicate with the engine control unit, which tweaks the steering settings based on vehicle speed and other factors.

Common Electric Power Steering Issues

• Sensor failure
• Motor failure
• Control unit failure
• Power supply problem
• Connector and wiring harness failure

Which Is Better?

​Modern hydraulic systems are tuned and provide excellent performance at any speed. Despite all this, hydraulic systems have one key advantage. Because the hydraulic fluid is constantly under pressure, it’s always subtly applying pressure to the steering wheel. As your tires roll over the road, you’ll get better feedback since you can feel the more delicate motions of your wheels. Many drivers value this feedback, which is why it’s worth pointing out.

Electric power steering is a relatively new technology with fewer moving parts and reduced weight. The electrical sensors allows these systems to be capable of adjusting the steering as needed, making electric power steering more popular in cars today compared to their hydraulic counterpart.
