In order to achieve the set vehicle targets, a suitable system must be developed. Due to the large number of variants and combinations of vehicle components and their interaction, vehicle development is a complex optimization task. Concept studies help to avoid late and costly changes from the outset.
In the case of battery electric vehicles, for example, questions about the battery pack and cells as well as the type of thermal management have to be answered. In addition, requirements for the electric motors, their coordination with the transmission and the operating strategies must be clarified.

CRUISE M models all relevant physical areas that occur in a vehicle. These include electrical networks, thermoregulation systems including air-conditioning circuits, mechanical and thermodynamic systems, and a generic data and function network for control tasks. In these networks, the software models complex reaction chemistry for electrochemical processes, heterogeneous catalysis, or homogeneous gas reactions.
This allows you to design and optimize both subsystems and the overall system in a network in detail.
Validated Vehicle Models – Versatile Development Aids
The AVL database currently includes more than 300 validated models of vehicles with a range of drive concepts – from conventional internal combustion engines to hybrid concepts and battery-powered and fuel-cell-driven vehicles. For example, there are validated AVL models of the Porsche Taycan, the Toyota Mirai II, the Toyota Yaris Hybrid, the Hyundai IONIQ 5, the Tesla Models 3 and Y, and many more vehicles. The database is being updated continuously and specific models can be created on request at any time.
Electrochemical Model for PEM and SO Fuel Cell
The software's proven real-time capability makes it ideal for developing operating strategies on virtual testbeds. This enables the analysis of operating conditions such as high-altitude operation or freeze-start strategies, which otherwise require complex tests on climatic testbeds. In addition, cell and stack geometries can be calculated at high resolution in 3-D with high performance.
The real-time modeling of thermodynamic systems in CRUISE M is ideally suited for the development and optimization of Balance of Plant (BoP) components for fuel cell media supply. For low-temperature proton exchange membrane (PEM) systems, tailored models for water balance and thermoregulation cycles are used. System models of solid oxide (SO) fuel cells include a number of catalysts for conditioning and post-conditioning of the media streams.
Multiscale and Multidomain Model for Battery Modules
The electrochemical behavior of battery cells is strongly influenced by temperature. Temperature in turn depends on both electrochemistry and thermal management of the battery module. CRUISE M provides you with a customized component that allows you to model these causal chains across multiple scales and domains effortlessly.
The module components for pouch, prismatic and cylindrical battery cells capture the electrical, thermal and mechanical coupling of the individual battery cells. This enables the analysis of thermal management concepts and fast charging strategies. You can choose between cell models from the CRUISE M library or your own models.
If you want to investigate new battery types virtually, CRUISE M offers extensive configuration options from electrode materials down to intercalation and aging chemistry. Importantly, your IP remains protected even when sharing models with partners.
Parameterization Wizards
To relieve you from the manual setting of parameters, CRUISE M has a number of wizards.
There are wizards available for parameterizing batteries, fuel cells, turbochargers, cylinders, pressure losses and much more. The wizards guide you through all input steps and you get a parameterized component quickly and easily.
Model Generators
Do you have only rough performance data of your system? CRUISE M creates a detailed, complete model from it, too.
Model generators are available for battery packs, fuel cell stacks, combustion engines, vehicle drives and much more. The model input parameters of all components are set automatically.
Our full-vehicle thermal models, developed in AVL CRUISE™ M, allow us to quickly evaluate design concepts and projected performance of thermal management components in next-generation BEVs. Using system simulation in CRUISE M, we can define realistic operating conditions early in the development process and efficiently manage the evolution of specifications through the development stages.
