Liebherr receives award for active personnel detection

The system detects people and objects around a wheel loader to prevent collisions

The German Association of Construction, Environmental and Mechanical Engineering (VDBUM) recently presented its 2022 VDBUM Award to Liebherr for its active personnel detection system.

Active personnel detection is an intelligent assistance system developed by Liebherr for its wheel loaders and uses sensors and artificial intelligence to automatically distinguish between persons and objects in order to specifically warn the machine operator of an accident that may result in personal injury.

If a person moves into the rear area of the wheel loader, the system alerts the operator at a greater distance than for static objects such as walls or columns. This intelligent classification reduces the number of unnecessary warning signals to make the machine operator’s work easier.

In addition to the targeted warning signals, the brake assistant and the incident map are further functions of the active personnel detection system that help to prevent accidents. As soon as the sensors detect a potential danger, the brake assistant automatically slows down the wheel loader. This eliminates the human reaction time required for conventional braking. This shortens the stopping distance, further reducing the frequency and severity of accidents.

With each warning signal, the assistance system transmits a GPS signal to Liebherr’s LiDAT data transmission and positioning system. Based on this, Liebherr provides the incident map, a visualisation of risk zones and potential accident sources on the plant site, for every operator of a wheel loader with active personnel detection in LiDAT. This allows the plant operator to take action to prevent accidents and thus increase safety.
