Simulation is an industry-proven method for testing and validating control algorithms and control software. dSPACE offers simulation models that support all stages of development, from function design to ECU testing.
The Automotive Simulation Models (ASM) provide comprehensive simulation solutions for four application areas: combustion engines, electric components, vehicle dynamics, and traffic environment.
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.
A powerful tool chain is available to make workflows more efficient:
ModelDesk is the intuitive user interface for defining and initiating simulations. By means of simple graphical methods, users can fine-tune vehicles, engines, roads, and the surrounding traffic to the simulation tasks.ASM – Real-time Simulation Models for Vehicle Development
ASM is a tool suite for simulating combustion engines, vehicle dynamics, electric components, and the traffic environment. The open Simulink models are used for model-based function development and in ECU tests on a hardware-in-the-loop (HIL) simulator.MotionDesk – Realistic 3-D Online Animation
MotionDesk visualizes the traffic and vehicle dynamics simulations in realistic virtual 3-D worlds. 3-D environments defined in ModelDesk, such as automatically generated buildings are immediately available in MotionDesk.
To enable seamless simulation processes, ASM supports various simulation platforms:
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.
