13.2 Collision avoidance

The application "Collision avoidance" uses movement-related information to avoid collisions . If the

movement-related information of the vehicle is provided, the accuracy of the collision avoidance

increases .

The collision avoidance is divided into three areas:

1: Live image display (→ „10.1 Live image display“)

2: Settings: Functions
For the collision avoidance the following settings are available .

With the "Collision avoidance mode", the type of the collision

avoidance can be set .

For the collision avoidance, one of the following modes can be

selected:

●

[Disabled]: The collision avoidance is deactivated .

●

[Intelligent]: The collision avoidance uses the movement-related

information of the objects and the vehicle

(→ „13.2.1 The "intelligent" collision avoidance mode“).

●

[Intelligent with side collision]: The collision avoidance uses the

movement-related information of the objects and the vehicle .

Additionally, the system looks out for potential collisions from

the side (→ „13.2.2 Collision avoidance mode "Intelligent with

side collision"“).

●

[Zone-based]: The collision avoidance monitors the created

zones with different priorities (→ „13.2.3 Collision avoidance

mode "zone-based"“).
