Abstatt – In order to prevent common accidents during construction machinery operation, such as collisions with people or obstacles, drivers need to have a constant overview of the entire area surrounding their vehicle, which often involves considerable mental stress and physical strain.
Electronic driver assistance systems also make construction sites safer, while making the work of construction operators easier. These techniques are the first stage of automated construction. "Bosch has therefore developed a modular concept of on-demand systems and sensors for comprehensive assistant functions specifically for construction machinery. In addition, together with Bosch Rexroth, we also offer a control unit that forms the heart of the automated machine," explains Stefan Schenk, off-highway product area specialist at Robert Bosch GmbH.
Flexible sensor concept for construction assistance systems
To make the vision of an automated construction site a reality, Bosch is already offering various assistance functions for construction vehicles today. They relieve the operator and make construction safer. Individual functions – such as load sensing in excavator buckets and a collision warning for safety in front of and behind the machine – can directly contribute to supporting the work. If these assistance systems detect people or objects in the danger zone, they warn the driver with a visual and/or audible warning and display the relevant objects on the screen. This gives the driver a clear view of the areas around the machine that are difficult to see.
The sensor concept consists of different ultrasonic and radar solutions, as well as a multi-camera system. This allows flexibility and the possibility to tailor the protection to the specific application and assistance functions. To this end, Bosch intends to exploit the know-how and proven core technologies available in the automotive industry and further develop them for off-highway applications. The systems can thus combine a high level of functional safety with exceptional robustness, even under the toughest of operating conditions.
Concept of manufacturer-specific assistance functions
For simple processing of optical sensor information, Bosch has developed the Off-Highway Vision unit, which displays the video stream of the multi-camera system. This is complemented by a kind of overlay that visually highlights objects detected by radar and ultrasonic sensors in their detection area. The electronic fusion of sensor data optimally combines the advantages of different sensors operating on different principles to increase the performance of the assistance system.
This provides construction machinery manufacturers with a validated and functional basic modular system that allows them to design and develop their own assistance systems on demand, using the "plug and play" principle. Possible functions include, for example, blind spot monitoring, object recognition and maneuvering assistance.
Automation in the construction industry
The currently available assistant functions are the first step towards the future use of fully automated and connected machines in the construction industry. Together, Bosch and Bosch Rexroth are supporting this process with the Off-Highway Robotics Controller (ORC), a complete system that can be adapted, tested and verified for the specific application. The automation software and hardware from Bosch can be seamlessly integrated into Bosch's digital ecosystem (BODAS), which supports digital transformation, thereby increasing productivity and efficiency. " With the systems from Bosch, the vision of the automated construction site of tomorrow is already within reach today," Schenk stressed.
CU.BE opens – A glimpse into the factory of the future, coming soon to our doorstep
In 2023, CU.BE, the unique, innovative experience center of Bosch Rexroth Kft., will open its doors in the Bosch Budapest Engineering Center of Bosch Hungary. CU.BE will be a place for Industry 4.0 awareness-raising and knowledge transfer, where visitors can learn about the benefits of a connected, automated and sustainable industrial ecosystem through practical examples. At CU.BE, visitors can learn about industrial digitalization through state-of-the-art tools such as augmented reality glasses.
