Software for Simulation and Analysis

Xentry Portal Truck [updated]

When developing race cars, efficiency is a must nowadays: The number of prototypes should be kept to a minimum, test time should be short, and costs as low as possible. AVL RACETECH offers appropriate solutions. With our extensive simulation tools, we are achieving a quantum leap in the development of high-performance components, systems and cars.

AVL VSM™ RACE

Fully-dynamic race simulation

AVL VSM™ RACE, AVL DRIVE™ RACE, AVL SIMBOOK™ RACE and AVL KINSOLVER™ RACE are the vehicle dynamics simulation toolchain for your unique racing applications. Each tool can be applied as a standalone solution, or as part of a fully integrated system.

Our in-house developed dynamic vehicle dynamics simulation, AVL VSM RACE, simulates and optimizes lap times – locally or in the cloud. The processing power is increased considerably by a cloud-based solution: Up to 100,000 laps can be simulated within a very short time, in order to determine the optimal set-up for a race car. AVL VSM RACE incorporates comprehensive models of the whole car and the environment. Every parameter can be varied automatically.

AVL DRIVE™ RACE

Automating data analysis

AVL DRIVE RACE automates data analysis – an important factor, given the high volume of data from cloud simulations. The software integrates and processes input from all conventional data acquisition systems. This allows conclusive comparisons between simulations and real car data.

AVL Simbook™ RACE

Visualizing results

AVL Simbook RACE visualizes the analyses acquired with AVL DRIVE RACE and helps the engineers at the racetrack to find optimal, real-time solutions for the set-up. The software can process more than 50,000 set-up variants and offers a multitude of presentation types. Car set-ups can be narrowed down and selected by specifying conditions, such as handling and stability, for every corner.

AVL Kinsolver™ RACE

Assessing impact

AVL Kinsolver RACE is a kinematics tool for chassis variants. It calculates how coordinate changes to the suspension affect lap time, handling and driving behavior. This is made possible by integrating software in the lap time simulation tool, AVL VSM RACE.

AVL CRUISE™ M

The multi-disciplinary simulation tool

AVL CRUISE M is the flexible solution for a wide range of applications to simulate the propulsion system of race cars. This includes analyses of the propulsion system concept, the design of subsystems, and the integration of virtual components. Furthermore, CRUISE M can also be used for Software-in-the-Loop (SiL) applications and run in Hardware-in-the-Loop (HiL) and testbed environments. Thanks to the customized solver infrastructure, the software performs extremely quick calculations – far quicker than real time.

AVL FIRE™ M

Optimized flow control

AVL FIRE M is a unique CFD simulation solution (computational fluid dynamics), with which we support the development of conventional and electrified propulsion systems. The software allows the precise calculation of single or multi-phase fluid flows and the associated thermal interactions. It can also accurately analyze aerodynamics, which are so important for race cars. In combination with our innovative embedded body method (EBM), the aerodynamic properties of the car design can be quickly and effectively optimized. Consistent propulsion predictions made by FIRE M are often the key factor behind faster lap times.

Historically, truck diagnostics required bulky, offline laptops running the DAS (Diagnostic Assistance System) software. Technicians were limited by local storage, slow updates via DVDs, and a lack of centralized data. The introduction of the Xentry Portal for trucks shifted the paradigm from a local software to a web-based SaaS (Software as a Service) platform. This portal connects via the Xentry Diagnostic Connect (XDC) hardware—a VCI (Vehicle Communication Interface)—to the truck’s CAN bus network. Unlike passenger car systems, the truck version is designed to withstand the rigors of fleet maintenance, offering remote diagnostics that allow a workshop in Chicago to pre-diagnose a truck stuck in Denver.

The Xentry Portal for trucks represents more than just a software update for a diagnostic tool; it is the digital cockpit for the modern transportation industry. By transforming the complex electrical architecture of a heavy-duty truck into a manageable, cloud-accessible interface, Daimler has empowered technicians to work smarter, not harder. While challenges regarding cost and connectivity remain, the Portal’s ability to reduce downtime and enable remote service is indispensable. As trucks progress toward Level 4 autonomy and electrification (e.g., the eCascadia), the Xentry Portal will remain the critical link between the human technician and the machine, ensuring that even the most advanced trucks stay on the road, hauling the global economy forward. xentry portal truck

Despite its power, the Xentry Portal Truck is not without drawbacks. The subscription model can be costly for independent garages, requiring a per-day or per-year license. Additionally, the system requires robust internet connectivity, which is not always available in rural tow yards or mobile service trucks. There is also a significant skill gap; veteran mechanics who grew up with wrenches and analog multimeters often struggle with the portal’s Windows-based interface and the requirement to constantly update their cybersecurity credentials.

Historically, the maintenance of commercial vehicles relied on fragmented systems. Technicians used standalone diagnostic hardware, such as the Mercedes-Benz Star Diagnosis system, which required periodic updates via physical discs or localized server connections. This process was often cumbersome and prone to version mismatches. The introduction of the XENTRY Portal marked a paradigm shift toward cloud computing. It replaced the older, fragmented infrastructure with a centralized, web-based interface. This shift ensures that every user, regardless of location, operates with the most current data, eliminating the lag time between a manufacturer's technical update and the workshop floor.

AVL CAMEO 4™

Testing and optimization software

Not only is it vital to optimize individual components, but also the entire system. AVL CAMEO 4™ is a powerful tool for this purpose – from data acquisition to automatic system optimization and parameter mapping. Furthermore, for electrified race cars, it is also possible to optimize the torque in electrical propulsion systems, improve model-based calibration of hybrid propulsion systems, and automatically perform inverter calibrations for electrical systems.

PreonLab

For rainwater management

Unsettled weather conditions are far from uncommon at racing events. With AVL’s PreonLab particle-based flow simulation, it is possible to incorporate difficult track conditions in calculations. Compared to conventional methods, PreonLab’s meshless CFD significantly reduces test times. High-performance visualizations and virtual wetting sensors provide detailed insights into everything that can happen when water and car meet.
