With the Drive Assist System (DAS), it is possible to implement integrated warning strategies for collision avoidance and to support the driver. The system offers 270-degree environment perception, which can be adapted to the specific use of the vehicle. The protective area, and therefore the necessary distance between the vehicle and the object, can be determined precisely by reading out polar coordinates. The direct integration of the DAS into the control of the industrial trucks makes it possible to implement various alarms and control interruptions, such as reducing speed or stopping the vehicle.
