Using sophisticated algorithms that analyze steering patterns, pedal inputs, and lane-keeping behavior, the Curvv can detect signs of driver fatigue before you even realize you're getting tired. The system establishes your normal driving patterns during the first 20 minutes of each journey, then monitors for deviations that indicate drowsiness. When detected, it first displays a coffee cup icon with an audible chime, suggesting a break. If ignored, it escalates to more prominent warnings and can even highlight nearby rest areas on the navigation map. The system is sensitive enough to recognize microsleep episodes—those dangerous moments when drivers briefly nod off without realizing it. This potentially life-saving feature is particularly valuable for those who frequently drive long distances or at night.
