Detailed Explanations of Mercedes Driver Assist Features
Active Distance Assist DISTRONIC: This feature is essentially an advanced cruise control system. It uses radar sensors to monitor the distance to the vehicle ahead. If the car ahead slows down, DISTRONIC will automatically slow your Mercedes down to maintain a safe following distance. It can even bring the car to a complete stop in stop-and-go traffic and then resume driving automatically. This is a great feature for reducing fatigue on long highway drives and making commutes in heavy traffic much less stressful.
Active Steering Assist: Working in tandem with DISTRONIC, Active Steering Assist provides gentle steering input to help keep the vehicle centered in its lane. It uses cameras to detect lane markings and can also follow the vehicle ahead. Some advanced versions even offer limited hands-off driving capabilities on certain well-marked highways. The system is designed to reduce driver workload and improve lane keeping, especially on long, monotonous stretches of road.
Active Lane Keeping Assist: This system is designed to prevent unintentional lane departures. If the vehicle begins to drift out of its lane without the turn signal activated, Active Lane Keeping Assist will first provide a visual and audible warning. If the driver doesn't respond, the system can automatically steer the vehicle back into the lane by applying the brakes on one side of the car. This is a crucial safety feature, especially for drivers who may experience fatigue or distraction.
Active Blind Spot Assist: Blind spots can be a major safety hazard. Active Blind Spot Assist uses radar sensors to monitor the areas on either side of the vehicle that are not visible in the mirrors. If a vehicle is detected in the blind spot, the system will alert the driver with a visual warning in the side mirror. If the driver attempts to change lanes while a vehicle is in the blind spot, the system will provide an audible warning and can even actively intervene by braking individual wheels to prevent a collision.
Active Brake Assist with Cross-Traffic Function: This comprehensive braking system is designed to help prevent or mitigate collisions with vehicles, pedestrians, and cyclists. It uses radar and camera sensors to detect potential collision situations. If a collision is imminent, the system will provide visual and audible warnings. If the driver doesn't respond, the system can automatically apply the brakes with varying degrees of force to reduce the severity of the impact or avoid the collision altogether. The Cross-Traffic Function adds an extra layer of safety by monitoring for crossing traffic at intersections.
Evasive Steering Assist: In emergency situations where a collision is unavoidable, Evasive Steering Assist can help the driver perform an evasive maneuver. The system analyzes the driver's steering input and adds calculated steering torque to help the driver steer around the obstacle. This can significantly improve the driver's ability to avoid a collision and maintain control of the vehicle.
Active Speed Limit Assist: This feature takes the guesswork out of knowing the speed limit. Active Speed Limit Assist uses information from the navigation system and camera-based speed limit recognition to automatically adjust the vehicle's speed to the posted speed limit. This can help drivers avoid speeding tickets and promote safer driving habits.
PRE-SAFE®: PRE-SAFE® is a suite of preventative safety features that prepare the vehicle and occupants for an impending collision. When the system detects a potential collision, it will automatically tighten the seatbelts, close the windows and sunroof, and adjust the headrests to the optimal position. These measures are designed to reduce the severity of injuries in the event of a collision.
PRE-SAFE® PLUS: PRE-SAFE® PLUS extends the capabilities of PRE-SAFE® by preparing for a potential rear-end collision. In addition to the standard PRE-SAFE® features, PRE-SAFE® PLUS can warn the driver of the following vehicle by flashing the hazard lights rapidly. It can also apply the brakes to reduce the risk of secondary collisions if the vehicle is struck from behind.
Route-Based Speed Adaptation: This smart feature uses navigation data to anticipate curves, intersections, and roundabouts. It then automatically adjusts the vehicle's speed to ensure a comfortable and safe ride. This can be particularly helpful on winding roads or in areas with frequent speed limit changes.
Traffic Sign Assist: Traffic Sign Assist displays detected speed limits and other traffic signs in the instrument cluster. This helps the driver stay informed about traffic regulations and avoid speeding tickets. The system can also recognize temporary speed limits in construction zones.
Parking Assist with Surround View System: Parking in tight spaces can be challenging. Parking Assist uses ultrasonic sensors and cameras to assist with parking maneuvers. The system can automatically steer the vehicle into parking spaces, both parallel and perpendicular. The Surround View System provides a 360-degree view of the vehicle's surroundings, making it easier to navigate tight spaces and avoid obstacles.
Car-to-X Communication: This technology allows the vehicle to communicate with other vehicles and infrastructure to share information about hazards, traffic conditions, and other relevant data. For example, a vehicle that has encountered a slippery road condition can send a warning message to other vehicles in the area. This can help improve situational awareness and prevent accidents.
Digital Light with Projection Function: Digital Light is an advanced headlight system that can project symbols and guidelines onto the road. This can improve visibility at night and enhance safety for pedestrians and cyclists. For example, the system can project arrows onto the road to indicate the direction of a turn or highlight pedestrians in the vehicle's path.
