Premiere: Active Blind Spot Assist and Active Lane Keeping Assist

Assistance systems are becoming increasingly important these days, providing support for drivers as they perform a complex activity. In the new Mercedes CLS, for example, proven technologies like ABS, ESP®and Brake Assist work alongside a dozen assistance systems to help prevent accidents and reduce their impact. These range from drowsiness detection to automatic full brake application on recognising that there is an acute risk of a collision, and from Adaptive Highbeam Assist to traffic sign recognition.

One new feature is the Active Blind Spot Assist. It warns the driver when changing lanes if a risk of collision is detected due to another vehicle in the neighbouring lane being in the so-called blind spot of the exterior mirror. If the driver ignores the warning and nevertheless initiates the lane-changing manoeuvre, the Active Blind Spot Assist intervenes. By applying braking force to the wheels on the opposite side of the vehicle, a yaw movement is created which counteracts the collision course.

Active Lane Keeping Assistis now also linked to the ESP® for the first time. This system kicks into action if the Mercedes vehicle inadvertently drifts over a solid line to the right or left of a lane. In such a case, a warning sign in the instrument cluster and vibration of the steering wheel give the driver warning. If the driver does not heed the warning in the case of the solid line, Active Lane Keeping Assist can use the ESP® to brake the opposite wheels and thereby prevent the vehicle from crossing the solid line. You can read more about these two assist systems in the section "Under the Microscope: Assist Systems".
