What type of steering system uses a hydraulic pump to assist the driver in steering?

A power steering system uses a hydraulic pump to provide assistance to the driver while steering. This system enhances steering performance by reducing the amount of effort needed to turn the steering wheel, especially at low speeds or when maneuvering in tight spaces. The hydraulic pump generates pressure that helps move the steering mechanism, making it easier for the driver to steer the vehicle without excessive strain.

In contrast, a manual steering system does not utilize any hydraulic assistance, requiring the driver to exert more physical effort to turn the steering wheel. Meanwhile, while rack and pinion systems can incorporate power steering, they themselves simply refer to the design of the mechanical components rather than a specific type of assistive technology. Electronic steering systems rely on electric motors instead of hydraulic pressure for assistance, distinguishing them from hydraulic power steering systems.
