In brief
The nearby area in front of the cabin has different risks than the far road.
Useful to know
Bosch's moving-off information system is designed for heavy goods vehicles. It detects vulnerable participants close to the vehicle and warns the driver when setting off or a low-speed manoeuvre. [1]
This task is different from maintaining distance at highway speed. The high cabin and the nearby area set specific requirements for surveillance. The presence of a warning does not mean an automatic stop in every variant. When equipping a fleet, consider the real coverage area and signals instead of taking all the forward radar functions as interchangeable.
