servostyrning

Servostyrning, often translated as power steering, is a system that assists the driver in turning the steering wheel of a vehicle. It reduces the physical effort required to maneuver the vehicle, especially at low speeds or when parking. This makes driving more comfortable and less physically demanding.

The core principle of servostyrning is to provide additional force to the steering mechanism. This is typically achieved through a hydraulic pump or an electric motor. In hydraulic systems, fluid pressure is generated and directed to a cylinder or rack that assists the steering motion. Electric systems use an electric motor to directly augment the driver's input.

There are several types of servostyrning systems. Hydraulic power steering (HPS) was the most common for many years, utilizing a belt-driven pump to maintain hydraulic pressure. Electric power steering (EPS) is becoming increasingly prevalent due to its energy efficiency and ability to offer variable assistance levels. Electrically assisted hydraulic steering (EHPS) combines elements of both.

The benefits of servostyrning include reduced steering effort, improved maneuverability, and enhanced driver comfort. It also plays a role in vehicle safety by allowing for quicker and more precise steering corrections. Modern servostyrning systems can also integrate with other electronic vehicle systems, such as stability control, to provide more sophisticated handling characteristics.
