Superior support in tailbacks.

More and more vehicles are pushing their way onto the motorways: cars, vans and heavy goods vehicles. And even more cars are joining them in the acceleration lane. Merging, accelerating, braking – and then changing lanes. The journey is tiring and the distances between the vehicles are short – often too short. If someone brakes at this point, a rear-end collision can be hard to avoid. Because the drivers have to react in a split second. And they do not always do that. Humans are not machines. Insufficient distance and therefore – if the worst comes to the worst – braking too late are some of the most common causes of accidents all over the world – both on motorways and on major or minor roads.

The Mercedes-Benz S-Class (V 222) comes with the latest generation of driving assistance systems.

Distance on the street – semi-autonomous driving.

This is where the latest generation of Mercedes-Benz assistance driving systems supports the driver with the Driving Assistance Package, as tailback management on motorways now already begins in advance of a tailback, including assistance in stop-and-go traffic and after the tailback has dissolved. When Active Distance Assist DISTRONIC with route-based speed adaptation is active, the car is able to respond to Live Traffic info – ideally before the driver or the radar and camera sensors can detect the hold-up or hazard. When a traffic tailback is detected, the speed is reduced to approx. 100 km/h as a precaution unless the driver specifically decides otherwise.

Assists in forming an emergency lane.

A new feature of Active Steering Assist is that it can support the driver with the emergency lane function on multi-lane roads. On motorways, at speeds under 60 km/h, the vehicle refers to detected lane markings and applies swarm intelligence to take its bearings from vehicles in the surrounding area. If none are detected, the car takes its bearings from the vehicle ahead, as previously.

Always ready to help: numerous other assistants are available.

It is not only by giving driver support in tailbacks that Mercedes-Benz further expands its Intelligent Drive and takes another major step towards autonomous driving. Active Distance Assist DISTRONIC and Active Steering Assist now provide even more comfortable support for the driver in keeping a safe distance and steering. With Active Speed Limit Assist, identified speed restrictions are adopted automatically in anticipatory mode. Active Lane Change Assist, Active Emergency Stop Assist and Evasive Steering Assist are also available.

Active Lane Change Assist.

When the driver wishes to change lanes on multi-lane roads (recognised by the navigation system) at speeds from 80 to 180 km/h, it is sufficient to nudge the indicator stalk in order to activate support. Within the next ten seconds, the sensor system checks together with the driver whether the next lane is clear in front of, alongside and behind the vehicle, also taking into account the speed of any other vehicles. If there is no other vehicle within the relevant safety zone, the driver is supported in changing lane. The initiated lane change is indicated in the instrument cluster and in the head-up display.

Active Emergency Stop Assist.

Active Emergency Stop Assist brakes the vehicle to a standstill in its lane if it detects that the driver is no longer actively driving the vehicle while it is on the move with Active Steering Assist switched on. If there is no steering wheel movement over a longer period when Active Steering Assist is active, the system gives the driver a visual and audible prompt to place his/her hands on the wheel. If the driver fails to respond after repeated visual and acoustic warnings by moving the steering wheel, accelerating, braking or operating the touch controls or other buttons on the steering wheel, the car is slowed down in the identified lane until it comes to a standstill. At speeds below approx. 60 km/h the traffic behind is warned by means of hazard warning lights. When the vehicle comes to a standstill, the parking brake is engaged automatically and the Mercedes-Benz emergency call system is activated. The vehicle is also unlocked, to allow first responders access to the interior. The functions are aborted as soon as the driver takes control of the vehicle again.

Evasive Steering Assist.

Within a speed range from 20 to 70 km/h, Evasive Steering Assist can help the driver to avoid a pedestrian detected by the assistance system using the radar sensors and stereo multi-purpose camera. If the driver initiates an evasive manoeuvre by turning the steering wheel, the system provides assistance by adding precisely calculated steering torque to support the movement of the steering wheel. This torque helps the driver to avoid the pedestrian in a controlled manner and then makes it easier to straighten the vehicle up again so that it can drive past safely. While the philosophy behind Evasive Steering Assist is to provide the driver with significant assistance, the initiative to take evasive action must come from the driver. This is because if evasive action were automatic, a previously inattentive driver might be so surprised by the spontaneous movement of the steering wheel that they might react incorrectly and, for example, attempt intuitively to steer in the opposite direction.

Within a speed range from 20 to 70 km/h, Evasive Steering Assist can help the driver to avoid dangerous situations involving pedestrians.

Traffic Sign Assist.

Image recognition and information from the digital road map in the navigation system allow determining the speed limit, no-overtaking zones and pedestrian crossings for the current route section and displaying them in the instrument cluster. Additional restrictions such as speed limits in wet conditions (warning when the windscreen wipers are switched on) or speed limits for trucks only are also taken into account or ignored as appropriate in the individual case concerned. The vehicle speed is compared with the speed limit. If set to do so by the driver, a visual/visual-audible warning is given if the speed limit is exceeded. No-entry signs are also recognised and the driver is prompted to check the vehicle’s direction of travel. A warning additionally appears in the instrument cluster and on the head-up display if pedestrians are detected in the area of a zebra crossing. Traffic Sign Assist is also separately available outside the assistance package.

Active Speed Limit Assist.

In conjunction with MBUX and the Driving Assistance Package, Active Speed Limit Assist, a selectable sub-function of Traffic Sign Assist, is also able to recognise sign gantries and road works signs captured by camera. Known limits, such as 50 km/h in built-up areas or 100 km/h on country roads, are also adopted from the navigation system. Active Distance Assist DISTRONIC adapts the vehicle’s speed to the recognised speed limits automatically (in combination with navigation and traffic sign recognition). In this case, the speed can be adapted in anticipatory fashion based on map data when entering towns. On roads without speed limits, such as stretches on German motorways, the recommended speed – in this case 130 km/h – is adopted as the set speed. This speed can be adjusted by the driver. The desired maximum speed is always adopted in the course of the journey when the speed limit is cancelled. It remains preset until the vehicle leaves the motorway or until the engine is switched off.
