Safe semi-autonomous driving to reduce stress
There are several safety and assistance systems based on the Mercedes-Benz Intelligent Drive concept to choose from. ATTENTION ASSIST with adjustable sensitivity, which can warn the driver of inattentiveness and drowsiness, is included as standard. Further standard equipment includes COLLISION PREVENTION ASSIST PLUS, which features an acoustic warning for the driver at speeds above 4 mph and Adaptive Brake Assist to help avoid collisions by boosting the braking effect in line with the current situation. When danger of a collision persists and the driver fails to respond, the system is able to carry out autonomous braking at speeds of up to 124 mph, thereby reducing the severity of collisions with slower or stopping vehicles or, in the best-case scenario, even avoiding the collision altogether. At speeds of up to 31 mph the system also brakes in response to stationary vehicles, and is thus able to help prevent rear-end collisions.
New assistance systems with substantially enhanced functions are optionally available, combining data from various sensor technologies such as radar sensors and a stereo camera as part of the Intelligent Drive concept to enhance comfort and safety:
DISTRONIC PLUS with Steering Assist is an adaptive cruise control system that can adjust the speed of the vehicle in line with a slower-moving vehicle ahead in a speed range from 0 to 124 mph if required. Likewise available from 0 to 124 mph, steering intervention helps the driver stay in lane. And at speeds below 81 mph, for example in traffic jams or when driving bumper to bumper, the system can follow the vehicle ahead even where there are no or unclear lane markings, thus enabling the driver to safety and comfortably follow the flow of traffic.
As well as vehicles ahead and stationary vehicles, the BAS PLUS Brake Assist System can also detect crossing traffic and boost the braking force if the driver fails to apply the brakes sufficiently; in addition to slower-moving, stopping and stationary vehicles, the PRE-SAFE® Brake can even detect pedestrians and brake autonomously if the driver fails to react, thus preventing accidents up to 31 mph and mitigating the severity of collisions at speeds of up to 45 mph. In flowing traffic the PRE-SAFE® Brake provides assistance according to the same mode of operation throughout the speed range from 4 to 124 mph.
Enhanced Active Lane Keeping Assist can now also prevent the vehicle from unintentionally drifting out of lane by applying the brakes on one side when the lane markings are solid or broken and there is a risk of collision, e.g. as a result of vehicles overtaking at high speed, parallel traffic or even oncoming traffic.
PRE-SAFE® PLUS extends the Intelligent Drive functions to take account of imminent rear impacts. It warns the following traffic by activating the rear hazard warning lights at increased frequency and initiating preventive
PRE-SAFE® occupant protection measures such as the reversible belt tensioner immediately prior to the impact. If the vehicle is stationary, the brakes are locked to reduce the forward jolt, which reduces the forces acting on the occupants and the risk of secondary collisions.
Optional assistance systems also include:
Active Parking Assist, which enables semi-automated parking with active steering and brake intervention in both parallel and end-on parking spaces. A 360° camera which is able to show the vehicle and its surroundings from various perspectives, including a virtual bird’s-eye view, thus assisting with parking and maneuvering.
