Over the years, steering systems have evolved significantly, leading to various types in use today. Understanding the different types of steering systems can help you appreciate the technology behind your vehicle’s handling capabilities. Here’s an overview of the main types of steering systems.
Hydraulic Power Steering (HPS)
Hydraulic power steering systems utilize a pump, usually driven by the vehicle’s engine, to provide hydraulic pressure that assists in steering. When the driver turns the steering wheel, the pressure is directed to one side of the steering gear, making it easier to turn the wheels. Despite its widespread use in the past, HPS is becoming less common in modern vehicles due to its reliance on engine power, which can reduce fuel efficiency.
Electric Power Steering (EPS)
Electric power steering systems use an electric motor to provide steering assistance. This system is more energy-efficient than hydraulic systems because the electric motor only operates when steering assistance is needed, reducing power drain on the engine and improving fuel economy. EPS systems also allow for more precise control and can be integrated with advanced driver-assistance systems (ADAS) for features like lane-keeping assist.
Electro-Hydraulic Power Steering (EHPS)
Electro-hydraulic power steering systems are a hybrid between hydraulic and electric systems. They use an electric motor to drive a hydraulic pump, which then provides the power assistance to the steering. EHPS offers the benefits of hydraulic systems, such as smooth steering feel, with the increased efficiency of an electrically driven pump.
Manual Steering
Manual steering systems, which rely solely on the driver’s physical effort to turn the wheels, are now mostly found in older vehicles and some lightweight sports cars.
