1. Understanding Mercedes-Benz Evasive Steering Assist

Mercedes-Benz Evasive Steering Assist is an advanced safety feature designed to help drivers avoid collisions with pedestrians or other vehicles. It works by adding calculated steering torque to the driver’s steering input when an emergency maneuver is detected. This system relies on various sensors and parameters to function effectively.

1.1. Key Components of Evasive Steering Assist

The Evasive Steering Assist system integrates several key components:

• Radar Sensors: These sensors monitor the vehicle’s surroundings, detecting the presence and movement of objects.
• Camera Systems: Cameras provide visual data to the system, helping to identify pedestrians, vehicles, and lane markings.
• Electronic Stability Program (ESP): ESP ensures the vehicle remains stable during emergency maneuvers.
• Steering Angle Sensor: This sensor measures the angle of the steering wheel, providing crucial data to the system.
• Control Unit: The control unit processes data from all sensors and activates the evasive steering assist function when necessary.

1.2. How Evasive Steering Assist Works

When the system detects an imminent collision, it assesses the driver’s steering input. If the driver initiates an evasive maneuver, the system provides additional steering torque in the appropriate direction. This support helps the driver steer around the obstacle while maintaining stability. The system is designed to be intuitive, so the driver remains in control of the vehicle at all times.

• Lane Departure: Indicates if the vehicle is drifting out of its lane.
• Object Recognition: Shows the types of objects the camera has identified (e.g., pedestrian, vehicle).
• Obstacle proximity: The values vary depending on the proximity of obstacles.

2.4. ESP System Data

The ESP system ensures vehicle stability during evasive maneuvers.

• Yaw Rate: Measures the vehicle’s rotation around its vertical axis.
• Lateral Acceleration: Indicates the vehicle’s acceleration in a sideways direction.
• Wheel Speed: Measures the speed of each wheel, helping to detect skidding or loss of traction.

3. Typical Live Data Values and Their Interpretation

Understanding the typical live data values for each parameter can help diagnose issues within the Evasive Steering Assist system.

3.1. Normal Operating Conditions

Under normal driving conditions, the following values are typical:

• Steering Angle: Close to 0 degrees when driving straight, with small variations depending on road conditions.
• Steering Angle Velocity: Low values during straight driving, increasing during turns.
• Target Distance: Varies depending on traffic, but should consistently update with changing distances.
• Yaw Rate: Close to 0 degrees per second when driving straight, increasing during turns.
