The AMG U88 system in the W465 G-Class plays an important role in enhancing the steering wheel feel when Active Cruise Control (ACC) is engaged, particularly by integrating the steering feedback with the vehicle's driving dynamics and systems for a more responsive and comfortable driving experience. Here’s how the AMG U88 system influences the steering wheel feel in this situation:

1. Improved Steering Feedback and Precision:

• When ACC is engaged, the AMG U88 system helps optimize the steering wheel feel by providing more refined and responsive steering inputs. As ACC takes over speed control, the system can adjust the steering response to make it smoother and more stable, reducing the need for constant steering adjustments by the driver.
• The system provides subtle steering feedback to help the driver feel more in control even when ACC is active, allowing them to stay connected with the vehicle while the system manages speed and distance.

2. Adaptive Steering Adjustment Based on Vehicle Speed:

• The U88 system adjusts the steering assistance to provide a more relaxed, comfortable, and stable feel at higher highway speeds when ACC is engaged. This helps the driver maintain a steady grip on the steering wheel while reducing the effort required to steer, especially on long drives.
• When ACC detects changes in speed or road conditions (such as curves or hill gradients), the U88 system fine-tunes the steering response to maintain optimal control without excessive effort from the driver.

3. Dynamic Steering Weighting for Comfort:

• ACC engagement often results in a need for a more consistent and less jerky steering input, especially in stop-and-go traffic or highway cruising. The AMG U88 system helps to adjust the steering weight dynamically, making it lighter and easier to handle when navigating slower speeds or heavy traffic.
• This adjustment can reduce fatigue during long highway drives, as the system ensures the steering wheel is comfortable to hold, with just the right amount of feedback.

4. Seamless Integration with Driver Assistance Systems:

• The AMG U88 system works in conjunction with other driver assistance features like lane-keeping assist and active steering correction, which are often active when ACC is engaged. The system integrates these features to provide a smooth and continuous driving experience, enhancing steering response when ACC is engaged, especially during long-distance or monotonous driving conditions.
• When these systems are active, the steering wheel will provide feedback to encourage the driver to remain within the lane or adjust steering inputs as necessary, ensuring a safer and more stable driving experience.

5. Steering Wheel Comfort and Reduced Driver Fatigue:

• One of the primary benefits of the AMG U88 system when ACC is engaged is its ability to reduce steering effort, especially on long, straight stretches of road. The steering wheel becomes lighter and easier to maneuver when needed, helping to reduce driver fatigue during extended periods of cruise control usage.
• On rougher or uneven terrain, the system may adjust the steering feedback to increase stability and ensure the vehicle stays within its lane while navigating subtle road deviations, all while keeping the steering feel consistent and controlled.

6. Haptic Feedback to Warn of Lane Departure:

• In some driving conditions, the AMG U88 system provides haptic feedback via the steering wheel when the vehicle is about to drift from its lane. When ACC is engaged, this feedback is seamlessly integrated into the system’s function, providing the driver with a gentle but clear warning if the vehicle is veering out of its lane.
• The steering wheel may provide a vibration or slight resistance to alert the driver, allowing them to correct the vehicle’s position with minimal disruption to the driving experience.

7. Reduced Overreaction and Steering Sensitivity:

• The U88 system helps reduce over-sensitivity in the steering when ACC is active, particularly when there are minor steering inputs from the driver or when the road has slight imperfections. It ensures that the steering wheel provides consistent and controlled feedback, making it easier for the driver to focus on the road without feeling constant micro-adjustments in the steering.

8. Stabilized Steering during Stop-and-Go Traffic:

• When ACC is engaged in stop-and-go traffic, the AMG U88 system enhances steering feedback by making the steering feel less twitchy. This allows for smooth, gradual movements of the steering wheel as the system adjusts the vehicle’s speed and maintains a safe distance from other vehicles. The driver can keep their hands on the wheel, feeling in control without needing to make frequent small steering corrections.

In summary, the AMG U88 system enhances the steering wheel feel when Active Cruise Control (ACC) is engaged by optimizing the steering response for comfort, reducing driver fatigue, and providing seamless integration with other driver assistance features. It ensures a smooth, controlled, and comfortable driving experience, whether on the highway or in stop-and-go traffic, with minimal driver intervention needed.
