Detecting road users

Both radar sensors (master controller and slave) assume this function for the most part independently of one another each in its own detection range. The position of the recorded road user in longitudinal direction and transverse direction are first determined.

Building on this, the road users are assigned to a driving lane. Here, a distinction is made between the driving lane of the vehicle itself, the neighboring driving lane on the left or right and driving lanes that are further away. If road users are in the "lane change zone", the approach speeds in relation to the vehicle are detected. If a road user is in the area of the blind spot, it is already sufficient to detect their presence. The exact position or speed is not decisive for a warning.
