The high traffic dynamics in city bus transport make great demands on the driver. The Sideguard Assist assistance system supports the driver primarily when turning towards the left in road traffic by making the driver aware of the presence of other road users and stationary obstacles and by warning if there is a danger of collision.
The system operates in multiple stages: in the first stage, it informs the driver, in the second stage it emits an additional warning.
If a moving object is located in the side monitoring zone, the driver is informed visually. A triangular-shaped yellow LED lamp lights up on the A0 pillar on the co-driver's side. A warning symbol additionally appears on the central display. If the driver initiates or continues an action that could lead to a collision, an additional visual warning is given. The LED lamp flashes first in yellow, then in red. After this the highest level alarm follows: a red flashing lamp accompanied by vibration of the driver's seat.
In addition, Sideguard Assist can perform the task of a lane change assist function; it works with the same warning cascade.
