Weighing Systems for Autonomous Trucks

Heavy-Duty Weighing Systems for Autonomous Truck Development

This product description focuses on high-precision weighing systems offered by Intercomp, specifically tailored for the needs of autonomous vehicle development projects. Testing and inspection of autonomous vehicles are critically important for safe and efficient operation, which cannot be achieved without precise weighing data. Our weighing systems ensure the necessary accuracy for real-time monitoring of vehicle weight distribution, axle loads, and total mass during the development phases.

Comprehensive Solutions for Autonomous Vehicles

The development of autonomous trucks is an extremely complex task that requires precise weight data to support vehicle dynamics, sensor calibration, and software algorithms. Intercomp scales are ideal for this environment as they are robust, portable, and extremely accurate, even under extreme conditions.

Main Application Areas in Autonomous Vehicle Development:

• Weight Distribution Validation: Measurement of weight shift occurring during various driving situations (acceleration, braking, cornering) to optimize vehicle stability and suspension load.
• Sensor Calibration: Calibration of axle load sensors and vehicle dynamics systems (e.g., ESP, stability control) using extremely precise external weight measurements as a reference.
• Prototype Testing: Quick and repeatable measurement of the weight of different hardware and software configurations to track performance changes.
• Axle Load Monitoring: Checking compliance with legal limits and ensuring optimal load distribution to maximize tire lifespan.

Technical Specifications and Benefits

Our systems are designed to withstand the challenges of high-traffic test tracks and varying weather conditions while providing industry-leading accuracy.

Main Advantages:

1. Outstanding Accuracy: The most modern load cell technology guarantees minimal measurement error, which is essential for the development of sophisticated autonomous systems.
2. Robust Construction: Weighing pads and sensors made from industrial-grade materials ensure long service life even under intensive use.
3. Portability and Quick Setup: Portable systems make it possible to perform measurements at any point on the test track with minimal setup time.
4. Integrability: Compatibility with the widest range of displays, data acquisition systems, and software, including wireless data transfer capabilities.

Product Family and Specifications

Although the raw text did not contain a specific model number for this application, based on Intercomp's wide portfolio, the most relevant categories and their general characteristics for autonomous truck development are as follows:

1. Portable Truck Scales

These systems are ideal for flexible testing workflows where the measurement station needs to be relocated quickly.

2. Low Profile Scales

These systems offer stability similar to built-in solutions but are easier to install and move than permanently installed weighbridges.

3. Weigh-In-Motion – WIM Systems

Weighing while in motion is essential for understanding the real-time behavior of autonomous systems.

• LS630-WIM™ / LS-WIM®: These systems enable axle load measurement while commercial vehicles are moving slowly.
• Advantage: Continuous data acquisition during vehicle passage, simulating real traffic conditions.
• Technológia: Use of special strip scales or full platforms.
• Accuracy: Exceptional accuracy at low speeds (Low-Speed WIM) compared to high-speed WIM systems.

Indicators, Software, and Data Management

The quality of the measurement data depends directly on the processing unit. Intercomp offers a wide selection for recording and analyzing measurements:

Indicators and Displays:

• Touchscreen CPUs (e.g., TAC30™): Intuitive user interface that simplifies the setup of complex measurement sequences and the display of real-time data.
• RFX® Wireless Handheld Indicators: Allows the operator to monitor measurements from a safe distance, thereby increasing safety on the test track.
• Data Acquisition Capabilities: The displays are capable of recording weight data, axle loads, and total vehicle weight, timestamped.

Software Support:

Post-analysis of measurements is essential for the development of autonomous vehicles. Software solutions (such as ACWeigh™ or analytical tools similar to it) make it possible:

1. Data Export: Exporting measured data in standard formats (e.g., CSV, XML) to vehicle dynamic simulation and analysis software.
2. Graphical Display: Visualization of weight changes over time or as a function of distance traveled.
3. Logging and Auditing: Detailed logging of every measurement to track the development process.

Application Notes for Autonomous Vehicles

During the development of autonomous systems, weight data are not just static values. The system must be capable of accurately measuring the shifting of the vehicle's load between the wheels. This is especially important when optimizing the vehicle's steering and braking systems.

The highly accurate, portable wheel weighing scales (such as PT300DW™ types) are ideally suited for measuring the vehicle under different load conditions (empty, half-loaded, fully loaded) and using this data for fine-tuning the vehicle model. The reliability of the system ensures that software developers can rely on the actual physical parameters of the vehicle rather than estimated values.

In summary: Intercomp weighing systems are the foundation of autonomous heavy-duty vehicle development, guaranteeing the necessary precision for realizing safe and efficient future transport solutions.
