October 20, 2022 – Safety is an essential part of Mercedes-Benz’s DNA and one of the central responsibilities the company has assumed – towards all road users. The priority of the brand with the star is to prevent accidents and improve the outcomes of accidents.
Brake control systems involved in more than 100 vehicle functions
TwoBox system for electric vehicles
More than 40 active driver assistance systems ensure safety
- Active Distance Assist DISTRONIC is an adaptive cruise control system that automatically maintains a preselected distance to vehicles in front on all road types.
- Active Steering Assist helps the driver stay in their lane. It can only be activated together with DISTRONIC.
- Active Lane Keeping Assist uses a camera to detect when road markings or road edges are crossed, helping the driver to avoid leaving the driving lane unintentionally.
- Active Blind Spot Assist monitors poorly visible areas and can help avoid accidents through braking intervention and warnings. Additionally, when the car is standing still, the Exit Warning function alerts occupants to the presence of road users such as passing cyclists. The ambient lighting in the door signals danger and can help to avoid a collision.
- Active Lane Change Assist cooperatively assists the driver when changing to an adjacent lane. A lane change to the right or left is only assisted if the sensors detect that the adjacent lane is separated from the present lane by interrupted lane markings, and no other vehicles are recognised in the relevant danger zone.
- Active Emergency Stop Assist brakes the vehicle to a standstill in its own lane if it recognises that the driver is no longer responding to the traffic situation for a longer period.
- Active Brake Assist uses the on-board sensors to register whether there is a risk of collision with vehicles travelling ahead, crossing or oncoming. The system can give the driver a visual and audible warning if a collision appears imminent. If the driver’s braking response is too weak, the system can also assist by increasing the brake pressure as the situation demands, and also initiate autonomous emergency braking if the driver fails to respond.
Improving the outcomes of accidents with PRE-SAFE® for 20 years
- In 2005, PRE-SAFE® was combined with Brake Assist PLUS (predecessor of today’s Active Brake Assist) to enable automatic closing of the side windows and inflation of side bolsters on multicontour front seats.
- This was followed in 2006 by the activation of other functions using radar technology. With the introduction of the third Driving Assistance package – featuring extensive sensor technology in the front and rear – imminent rear-end collisions can also be detected. In the event of an imminent rear end collision, PRE-SAFE® PLUS warns the traffic following behind by means of rapidly flashing warning lights.
- Introduced in 2016, PRE-SAFE® Impulse Side lifts the driver or front passenger inwards out of the danger zone just before a side impact.
- PRE-SAFE® Sound marked another addition in 2016: protection against hearing loss. In rare cases, the loud noise of a car accident can lead to impaired hearing over time. PRE-SAFE® Sound can trigger a reflex in the inner ear that acts like biomechanical hearing protection. In certain dangerous situations just before a possible collision, the system causes the vehicle’s speakers to emit a rushing sound (pink noise). The aim is to cause a tiny muscle in the inner ear to contract (acoustic reflex), which affects the coupling of the eardrum, preparing hearing for high sound pressures.
Central software as a new development focus
Clear goal for the future: Accident-free driving by 2050
At Mercedes-Benz, we are pursuing our vision of accident-free driving. In other words: no more accidents involving a Mercedes vehicle. We are continuing to work toward this goal at full speed. Highly automated and autonomous driving will be a decisive contributor to its success. After all, vehicle safety has always been at the core of the Mercedes-Benz brand – and we want to continue to expand this claim in the future.
