Ajonhallintajärjestelmä

Ajonhallintajärjestelmä, often abbreviated as ESC (Electronic Stability Control) in English, is an important safety feature in modern vehicles. Its primary function is to help drivers maintain control of their vehicle during challenging driving situations, such as skidding or sudden evasive maneuvers. The system works by monitoring individual wheel speeds and the vehicle's steering angle.

When the ajonhallintajärjestelmä detects that the vehicle is about to lose traction or deviate from the driver's intended path, it can intervene automatically. This intervention typically involves selectively applying the brakes to one or more wheels and, in some cases, reducing engine power. By braking individual wheels, the system creates a counter-force that helps to steer the vehicle back onto its intended course, preventing or mitigating dangerous situations like spins or rollovers.

The effectiveness of the ajonhallintajärjestelmä relies on a complex network of sensors and a sophisticated control unit. These components continuously analyze vehicle dynamics and compare them against the driver's inputs. Most modern vehicles are equipped with this technology as standard, as it has been proven to significantly reduce the number of single-vehicle accidents and improve overall road safety. Drivers should be aware that while the ajonhallintajärjestelmä is a powerful tool, it is not a substitute for attentive driving and appropriate speed for road conditions.
