    DRIVE PILOT represents Mercedes-Benz’s Level 2 semi-autonomous driving system, designed for use on divided highways under specific conditions. Below is a flowchart-style explanation of its operation and limitations:

    1. System Activation

    DRIVE PILOT engages when the vehicle is traveling on mapped highways with clearly marked lanes, at speeds between 0–60 km/h (0–37 mph) for urban use or up to 210 km/h (130 mph) on highways. The driver must keep hands on the steering wheel; failure to do so for more than 20 seconds triggers a warning, and the system deactivates after 25 seconds.

    2. Lane Centering and Speed Regulation

    The system uses stereo cameras, radar, and ultrasonic sensors to monitor lane markings and traffic. It maintains a set distance from the vehicle ahead via adaptive cruise control and centers the vehicle within its lane using subtle steering corrections.

    3. Driver Monitoring and Intervention

    A camera tracks the driver’s attention. If the system detects inattentiveness (e.g., hands off the wheel or gaze diverted), it issues auditory and haptic warnings. If the driver fails to respond, DRIVE PILOT transitions to a reduced-speed mode (30 km/h or 19 mph) and eventually halts the vehicle.

    4. Limitations and Deactivation Triggers

    DRIVE PILOT does not operate in the following scenarios:

    • Unmarked or poorly lit roads.
    • Heavy traffic or construction zones.
    • Weather conditions reducing sensor accuracy (e.g., heavy rain, snow, or fog).
    • If the vehicle’s navigation system lacks up-to-date map data for the route.
    • When the driver manually overrides the system (e.g., for overtaking or emergency maneuvers).

    Note: DRIVE PILOT is not a fully autonomous system. The driver remains responsible for all driving tasks, including monitoring the environment and intervening when required.
