ANTI-LOCK BRAKING SYSTEM (ABS)
The ABS system improves active safety by preventing wheel lock during braking. Wheel lock is extremely dangerous, since the front wheels become unsteerable, and locked rear wheels can cause the vehicle to skid and swerve into the other lane.
Under any conditions (driving straight, cornering, on asphalt, icy or wet roads, etc.) the ABS system reduces braking distance to a minimum.
In principle, during every braking maneuver the ABS must perform two tasks, ensuring
- directional stability on roads with different surface types (asphalt, concrete) and in different conditions (icy, muddy, snow-covered or wet roads) - reliable steering control and maneuverability of the vehicle under these conditions
These requirements need important explanations.
ABS does not override the laws of physics. The system cannot prevent the consequences of braking with insufficient distance to the vehicle ahead, taking corners at excessive speed, or driving under hydroplaning conditions. These consequences remain the responsibility of the driver. The presence of ABS, which provides enhanced safety potential, should not encourage you to drive recklessly.
