Längsdrift

Längsdrift is a German term that translates to "longitudinal drift" or "lateral drift" and is primarily used in the context of automotive engineering, specifically concerning vehicle handling and stability. It refers to the tendency of a vehicle's tires to slip sideways relative to the direction of travel, independent of any steering input. This slip is a consequence of forces acting on the tire that are not perfectly aligned with its direction of motion.

Several factors can contribute to längsdrift. These include excessive cornering forces, sudden changes in road surface conditions like ice or gravel, improper tire inflation, or suspension geometry issues. When a tire experiences längsdrift, it means the tire is not rolling purely in the direction it is pointed, leading to a loss of grip and potentially unpredictable vehicle behavior.

Understanding and controlling längsdrift is crucial for vehicle dynamics and safety. Modern electronic stability control (ESC) systems actively monitor and counteract excessive tire slip to maintain vehicle control. By braking individual wheels or reducing engine power, these systems can help correct the vehicle's path and prevent loss of control, especially during emergency maneuvers or in challenging road conditions. In essence, längsdrift is a fundamental concept in understanding how tires interact with the road and how vehicles maintain their intended trajectory.
