Liebherr awarded for active personnel detection

The German Association of Construction, Environmental, and Mechanical Engineering (VDBUM) has awarded active personnel detection with the 2022 VDBUM Award

Active personnel detection is an intelligent assistance system developed by Liebherr for the group’s wheel loaders.

It 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 column, reducing 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 incident, the brake assistant automatically slows down the wheel loader. This eliminates the human reaction time required for conventional braking and shortens the stopping distance by potentially crucial metres, 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 help increase safety.
