Introduction
Hydraulic power steering, a system involving a pump, cylinder, and valves, has been the standard for decades. It controls hydraulic fluid flow, with the pump’s speed proportional to motor speed. Valve control helps maintain optimal responsiveness, and advancements in engineering have made fine tuning possible.
Hydraulic system pros
The hydraulic steering system enhances driver handling by providing intuitive decision-making and a safer driving environment, making it a popular choice for high-end sports cars and race cars.
Flaws in hydraulic power steering system
Hydraulic system cons
Hydraulic system has cons such as power steering fluid requirement, annual maintenance, frequent fluid leaks, impacting fuel economy, complex system with more moving parts, and increased engine space.
Hydraulic power steering path
The vehicle is susceptible to numerous potential issues, including power steering fluid leaks and pump issues, which drivers may not always understand the cost of repairs.
What is electric power steering?
The electric power steering, lived in 1876
This was invented long before the first electric power steering, lived in 1876.this was invented long before the first automobile was manufactured but it was not until the 1970s that it was widely used.
Electric motor
An electric motor is used in the steering system in place of a hydraulic fluid pump
(ECU) Electric count unit
The electronic count unit (ECU) and sensors exchange data to adjust steering settings based on vehicle speed. Despite initial bugs, advancements in engineering improve this system in contemporary cars.
Electric system pros
The design is simpler, less complicated, and efficient, eliminating the need for power steering fluid and connecting to driver asset features like automated parking and lane keeping assistance.
Software updates can enhance system accuracy in self-driving cars, despite their popularity. However, drawbacks include potential issues with accuracy.
Electric system cons
Manufacturers are working on improving electric power steering system feel, aiming to provide feedback in the coming years to enhance the user experience.
Key differences
Maintenance and repair needs
Power steering fluid is required by the hydraulic system, and its maintenance schedule typically requires a change. The average cost is $25-$125. Although not a significant expense, some drivers may opt for it. Electrical power steering systems have less upkeep and are more prone to issues like leaks and belt problems. Hydraulic systems are more complex and require more space and weight, reducing vehicle fuel efficiency.
Handling
Hydraulic power steering provides superior driving experience, while electric power steering offers reliable feedback. Manufacturers continuously refine systems to improve performance.
Power source
The hydraulic steering system, powered by an engine-driven belt, has slightly higher fuel consumption, but electric power steering improves gas mileage by using power only when the wheel is turned.
Conclusion
New car buyers often see electric power steering as standard equipment, but understanding the difference is crucial, especially for older pre-owned cars. While hydraulic systems may feel better, they require more frequent maintenance and fuel consumption. Technicians now focus on software bugs and electric motor failures.
