With its HPX.ai-vision high-automation platform, STW offers the perfect basis for implementing future-proof assistance systems. Thanks to the powerful multiprocessor architecture, machine manufacturers can gradually integrate new software modules, such as the „Safety Assist“. In addition, when used in conjunction with person recognition software, the system meets the criteria for funding by German associations BG Bau and SVLFG.
At this year's Agritechnica in Hanover, STW is presenting various fields of application for its high-performance platform HPX.ai-vision. It can be equipped with a variety of software modules that help mobile machines achieve maximum safety and efficiency. Christian Klausner, Director of Product Management at STW, explains: "Assistance system software is developing rapidly. Many technologies from the automotive industry are finding their way into the off-highway sector. However, this is an iterative process that will continue for several years. To be truly future-proof, manufacturers of agricultural, construction, forestry, and municipal machinery need robust, high-performance computers that are equipped to handle the software requirements of the coming years."
Robust and high-performance
The HPX controller from STW provides a powerful multiprocessor architecture with dedicated GPU acceleration as an MPSoC system as the hardware basis for this. Depending on the configuration, multiple GMSL2 cameras and LIDAR sensors can be connected to ensure precise detection of the environment. If required, additional Ethernet-based cameras or sensor technologies can be integrated to enable even more comprehensive process monitoring. Various assistance systems that previously required multiple subsystems can be combined in a central control system with this solution. This reduces both complexity and costs.
The HPX.ai-vision can be operated without active cooling across the entire temperature range from -40°C to +85°C and is functionally safe with certification up to ASIL B. This means that the high-performance platform also meets the typical requirements of mobile machines in terms of the robustness of the electronic components used.
Powerful software partners
At its market launch, STW offered the HPX.ai-vision as a plug-and-play bundle with pre-installed Birdview software. Since then, several well-known software partners have joined the platform, whose solutions can be integrated as user-friendly modules. Among others, STW cooperates with the AI specialists from Driveblocks in Munich and the experts for dynamic 360-degree systems from TES Electronic Solutions, based in Leinfelden-Echterdingen, Germany.
The TES 3D Surround View (TSV) software from TES Electronic Solutions makes it possible to display any predefined viewing angle around the machine in addition to the classic bird's-eye view. The vehicle itself is displayed in the correct perspective in the calculated image. Displaying multi-views is possible, allowing several sensitive viewing angles to be visible on one display at the same time – a major plus in terms of safety and driver comfort.
Driveblocks enables the integration of resource-efficient AI for person and object recognition as well as a 360-degree camera and LIDAR-based safeguarding function on the HPX.ai-vision. This combination not only increases safety in demanding application scenarios, but also supports more precise navigation and real-time environment detection. Intelligent sensor fusion and AI-supported decision-making processes minimize the risk of accidents and optimize machine operation.
In internal tests, the system has met the requirements of GS-BAU-71 for retrofittable camera-based personnel detection systems. It is therefore potentially eligible for funding, both through the occupational safety premiums of the German BG Bau and the occupational safety program of the German Social Insurance for Agriculture, Forestry, and Horticulture (SVLFG). Construction, agricultural, and forestry machinery equipped with this system can be certified for these subsidies, provided that the respective model has been individually tested by an accredited testing center in accordance with the GS-BAU-71 test principles.

Increased safety with Brake Assist
Equipped with these software systems and based on Driveblocks algorithms, HPX.ai-vision will enable maximum flexibility in development and safety in operation with Safety Assist in the future. This collaborative development by STW and Driveblocks forms the basis for the design and implementation of software-defined vehicles (SDVs). The Safety Assist system offers the possibility of combining and linking various previously independent assistance systems on a high-performance controller. This reduces integration and development costs and facilitates the implementation of functionally safe systems that bring together sensors and actuators.
One example of the system's potential is the integration of adaptive brake assistance systems. These emergency braking systems are familiar from modern passenger cars. If an obstacle suddenly appears in front of the vehicle, the vehicle brakes automatically to prevent a collision or reduce the consequences of an impact.
However, the Safety Assist goes one step further. Equipped with the right software modules, the system is able to calculate the paths and directions of movement of people and vehicles in order to assess the potential danger. This means that people and vehicles detected at a distance do not trigger braking. The operator can operate their machine with maximum productivity and performance. If objects move close to a vehicle equipped with such a brake assistant, light braking and an acoustic and/or visual warning may be triggered. If obstacles enter the predefined immediate danger zone, emergency braking is performed.
The combination of person and object detection with the connection to the machine's braking system thus avoids disruptive continuous alarms or unnecessary braking. The machine operator is only supported when necessary. In addition to improved safety, gradual braking ensures higher productivity and improved driving comfort.
All that is required to integrate the brake assistant is a digital connection to the braking system, for example via CAN. Functional safety is ensured by the necessary protocols such as CANopen Safety. In principle, it is possible to additionally couple HPX.ai-vision with steer-by-wire steering systems in order to implement fully autonomous collision avoidance assistants.
Christian Klausner concludes: "Assistance systems are constantly evolving. Less complex surround view systems that simply provide a better overview of the vehicle and its surroundings are still in demand for less safety-critical applications. Where large machines and people work closely together, e.g., on construction sites, airfields, or narrow farmyards, systems with person recognition are the means of choice. And in the long term, systems will prevail in which the machine operator performs a supervisory function and the vehicle evades obstacles independently. This requires a connection to the braking, steering, and drive systems. Our HPX.ai-vision makes all this possible and is therefore a future-proof solution for all demanding machine manufacturers.”
STW will be demonstrating what is possible with HPX.ai-vision and the Safety Assist System at Agritechnica 2025 in Hanover. Interested visitors to the trade fair will find STW and the high-performance platform in Hall 17 at Stand D12.
