Safety assistance systems

By your side.

No matter what you use your truck for: the most important thing is accident-free driving. The Mercedes‑Benz Trucks assistance systems can help you keep an eye on everything and manoeuvre your vehicle on the road in a controlled manner – especially in critical situations. We not only fulfil the legal EU standards for safety assistance systems that have applied since mid-2024 – in some cases we even exceed them. But from a Mercedes‑Benz truck, we would expect nothing less.

Turning and lane changing

Active Sideguard Assist 2

The advanced, second generation of Active Sideguard Assist can support drivers across the entire speed range when changing lanes or turning with restricted visibility. What’s more, the two-stage warning system can alert drivers to potential hazards so that they can mitigate a critical traffic situation in good time.

  • Monitoring on driver and front passenger sides 
  • Two-stage warning system when a hazard is identified (first visual information, then visual and audible warning) 
  • Detects and warns of hazards across the entire speed range
  • Active brake intervention when turning to the right (right-hand traffic) or left (left-hand traffic) in the speed range up to 20 km/h if there is no reaction to visual and audible warnings
Brakes

Active Brake Assist 6 Plus

Active Brake Assist already fulfils the AEBS (Advanced Emergency Braking System) legislation, which will come into force in September 2028. The 270‑degree fusion technology features enhanced reality capture. This enables the system to react even faster to critical situations. As a result, greater accident prevention can be achieved for vehicles up to 90 km/h as well as for pedestrians and cyclists up to 60 km/h. The system now also clearly indicates if it is not yet fully active.

  • Update to the existing Active Brake Assist 6 in order to meet the new AEBS legislation for 09/28 at an early stage
  • 270° environment detection by camera technology plus additional short-range sensors on the headlamps and to the side
  • Can now better react to pedestrians and cyclists up to 60 km/h 
  • Can achieve significantly higher accident prevention for moving and stationary vehicles up to 90 km/h
  • Can react to moving and stationary vehicles on bends with large radii, e.g. on the motorway
  • Two-level warning system: if danger is detected, a visual and acoustic warning is initially issued with simultaneous partial braking and then, if the driver fails to react, automated full braking
  • Visual warning if the full system output is not yet available after 15 seconds of driving at over 10 km/h 
  • Radar technology for better functionality even in low visibility conditions
Moving off and manoeuvring

Front Guard Assist

Front Guard Assist can increase driving safety even before drivers set off: it monitors the traffic area in front of the vehicle and supports the driver in the speed range up to 15 km/h, e.g. when the vehicle is stationary, when moving off or at junctions. If the system detects moving objects in front of the vehicle, such as people, the warning system can help the driver react in good time with a two-stage hazard warning.

  • Active in driving situations up to 15 km/h
  • The monitoring range covers the blind spot in front of the vehicle (up to approx. 4 m) across the full width of the vehicle
  • Two-stage warning system when a hazard is detected (visual warning, then visual and audible warning)
Keeping in lane and keeping a safe distance

Active Drive Assist 3

The latest generation of Active Drive Assist offers even more safety and comfort, especially on long journeys. From automatic proximity control (including in stop-and-go traffic in traffic jams) to smart Lane Keeping Assist and the Emergency Steering function: if there is a risk of collision when changing lanes, the system can actively intervene and steer your truck back into its own lane. For example, if a health problem causes you to stop driving, the hands-off warning can initiate controlled emergency braking if you fail to react.

  • Promotes economical and comfortable driving, especially on the motorway
  • Can provide support across the entire speed range
  • Automatic distance control with stop-and-go (moving off and stopping in traffic jams)
  • Active Lane Keeping Assist
  • Can prevent the vehicle from leaving its lane by active steering intervention
  • Can progressively brake the vehicle to a standstill in the event of driver inactivity
  • Can steer the vehicle back into its own lane when changing lanes if a risk of collision with vehicles in the next lane is detected
Staying alert

Attention Assist 2

Attention Assist 2 can help to prevent accidents in the event of driver inattentiveness or fatigue by means of visual and acoustic warnings. Using an integrated camera, it records the driver’s visual attention based on their viewing angle as well as the driver’s level of fatigue. All data remains inside the vehicle.

Graphic of Front Guard Assist with truck and other road users in front of the truck
  • Improves road safety
  • Uses an integrated infrared camera to detect the position of the driver's head and pupils
  • Emits visual and acoustic warnings if it detects signs of drowsiness or distraction
  • This is a closed system, i.e. all data remains inside the vehicle and is permanently deleted by the system after 15 minutes
