    │ AMG Damping Process Flow │
    ├───────────────────┬───────────────────┬───────────────────────┤
    │ Input Sources │ Control Unit │ Actuator Response │
    ├───────────────────┼───────────────────┼───────────────────────┤
    │ - Accelerometers │ - ECU (Electronic │ - Adjusts damping │
    │ - Wheel sensors │ Control Unit) │ force in real-time │
    │ - Road surface │ - Processes data │ - Reduces body roll │
    │ condition │ via algorithms │ - Minimizes dive/squat│
    │ sensors │ (PID, fuzzy │ - Optimizes contact │
    │ - Steering angle │ logic) │ patch compliance │
    └───────────────────┴───────────────────┴───────────────────────┘

    Key Adjustments:
