The Automotive Simulation Models (ASM) provide comprehensive simulation solutions for four application areas: combustion engines, electric components, vehicle dynamics, and traffic environment.

Combustion Engines

The ASM engine models are ideal for developing and testing engine and exhaust gas aftertreatment ECUs. They simulate a combustion engine, including all the necessary components, as a controlled system for the ECUs. There are models for diesel and gasoline engines with different injection systems and exhaust gas aftertreatment systems. The real-time simulations can be performed with mean-value models or with physical models. 

Vehicle Dynamics

The ASM Vehicle Dynamics Model is an excellent basis for developing and testing vehicle dynamics ECUs, such as ESP, steering and active damping ECUs. They are ideal for vehicle dynamics investigations in early development phases. Models for passenger vehicles, trucks and trailers are available. A user interface lets users configure the vehicles and define maneuvers and roads graphically.

Electrical Components

Vehicle electrical systems, electric drives and inverters, as well as starter batteries and high-voltage batteries, are all virtualized precisely by the simulation model for electric components. The model supports tasks such as developing and testing hybrid ECUs, battery management systems and indicator light controls. Users can parameterize the modeled components graphically to fit the real controlled system exactly.

Driver Assistance Systems

A comprehensive traffic model with road users and environmental objects is available for developing and testing driver assistance systems. The various sensor models in the simulated test vehicle detect the other road users and also the static and dynamic objects in the virtual environment. The traffic scenarios and the environment are easily defined graphically.

To enable seamless simulation processes, ASM supports various simulation platforms: 

  • dSPACE Simulator
  • VEOS
  • PC with MATLAB®/Simulink®

Depending on the platform, the simulation is performed with the controller model, control software or the control hardware (ECU) in the control loop. The same simulation model is used in each case. The models therefore support the entire development process, from function development to ECU testing.
