0:00 AEB Rear (Autonomous Emergency Braking) – braking for pedestrians when reversing
0:21 Rear-axle steering
The interaction between the front-axle and rear-axle steering is configured to ensure agile responsiveness in urban and country traffic together with a very high level of stability. This results in e.g. small side-slip angles and a high level of yaw suppression. At high speeds the focus is more on stability, though without compromising precision and responsiveness.
This added value is achieved by integrated actuation of the steering and brakes (ESP®), and considerably improves handling safety as a result.
Customers have a choice of two variants of the optional rear-axle steering: 4.5° and 10° rear-axle steering. In the 10° variant the wheel size is limited to 255/40 R 20, allowing a larger wheel angle. These are the other differences:
0:47 Digital light
In each headlamp, Digital Light has a light module with three extremely powerful LEDs whose light is refracted and directed by 1.3 million micro-mirrors. The resolution is therefore more than 2.6 million pixels per vehicle. The micro-mirrors occupy the same area as a thumbnail. A control unit with a powerful graphic processor uses an HDMI-like connection to generate a continuous video stream to the mirrors.
1:28 Parking Package with 360° – Camera
– The four individual camera images are combined into a three-dimensional
image of the vehicle’s surroundings
– Seven different views and zooming are possible
– Automatic camera (changes the perspective according to situation)
– Model vehicle is rendered in real time
– Shows status such as indicating or braking
– Visualises obstructions in the field of vision, e.g. open doors
8:01 Active Steering Assist with Active Active Emergency Stop Assist
This helps the driver to follow the driving lane at speeds up to 210 km/h. New features:
– additional lane recognition by a 360° camera
– significantly improved availability and performance on bends on country roads
– improved lane centering on motorways
– situation-specific off-centred driving (e.g. forming an emergency lane, but also following the road edge on country roads with no centre marking)
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. In the new S-Class this still works if Active Distance Assist DISTRONIC with Steering Assist is not switched on.
8:57 Active Blind Spot Assist and Exit warning function
Active Blind Spot Assist can give a visual warning – and if the indicators are operated also an audible warning – of potential lateral collisions in a speed range from around 10 to 200 km/h. If the driver ignores the warnings and still initiates a lane-change, the system can take corrective action by one-sided braking intervention at the last moment if the speed exceeds 30 km/h.
9:33 Attention Assist with microsleep detection
This system included as standard is able to recognise typical signs of drowsiness and driver inattention, and displays a warning message prompting him/her to take a break. The additional microsleep warning is a new feature. This is based on monitoring of the driver’s eyelid movements by a camera in the driver display (only in conjunction with certain optional equipment). The microsleep warning function is already active from a speed of 20 km/h.
10:07 Active Distance Assist DISTRONIC and Active Steering Assist
Active Distance Assist DISTRONIC
On all types of roads – motorways, country roads or in town – this intelligent system can automatically maintain a preset distance from vehicles ahead. Active Steering Assist helps the driver to follow the driving lane at speeds up to 210 km/h.
10:51 Active Blind Spot Assist
Active Blind Spot Assist can give a visual warning – and if the indicators are operated also an audible warning – of potential lateral collisions in a speed range from around 10 to 200 km/h. If the driver ignores the warnings and still initiates a lane-change, the system can take corrective action by one-sided braking intervention at the last moment if the speed exceeds 30 km/h. When the vehicle is stationary, the exit warning function can warn against exiting because a vehicle (also bicycles) is passing within the critical area.
11:16 Active Lane Changing Assist
Active Lane Changing Assist cooperatively assists the driver of the new S-Class when moving 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 an interrupted lane marking, and no other vehicles are recognised in the relevant danger zone.
