rattrotasjon

Rattrotasjon, often translated as steering wheel rotation, refers to the amount a steering wheel is turned during vehicle operation. It is a fundamental concept in vehicle control, directly influencing the direction of the vehicle's wheels. The degree of rotation is typically measured in degrees or fractions of a full turn (e.g., a quarter turn, a half turn, a full turn).

In practical terms, a small amount of rattrotasjon results in a subtle change in direction, while a larger rotation causes a more significant turn. The relationship between steering wheel input and the resulting vehicle direction is determined by the steering ratio of the vehicle. A lower steering ratio means more steering wheel rotation is required to achieve the same wheel angle, often providing a more comfortable and less sensitive steering feel. Conversely, a higher steering ratio results in quicker steering response, where a small steering wheel input produces a large change in direction.

Modern vehicles often employ power steering systems, which assist the driver in rotating the steering wheel, reducing the physical effort required. The electronic control units in many vehicles also manage the level of power assistance, sometimes varying it based on vehicle speed. Understanding rattrotasjon is crucial for safe driving, particularly when navigating turns, making lane changes, and parking. Precise control of the steering wheel is essential for maintaining the desired path and avoiding hazards.
