What is ASM Vehicle Dynamics?
ASM Vehicle Dynamics is a real-time capable vehicle dynamics model for the physically precise simulation of vehicle behavior. It realistically simulates the interaction of chassis, tires, steering, brakes and powertrain, and enables the virtual development, validation and validation of modern vehicle systems. ASM Vehicle Dynamics is specially optimized for use on the platforms dSPACE SCALEXIO and dSPACE VEOS, where it ensures maximum performance, determinism and model stability. The combination of ASM Vehicle Dynamics and SCALEXIO and/or VEOS forms a powerful, integrated simulation solution for model-in-the-loop (MIL), software-in-the-loop (SIL), and hardware-in-the-loop (HIL) applications and creates ideal conditions for efficient and reproducible tests throughout the entire development process.
Typical Application Areas
- ADAS & Automated Driving Development
Simulation and validation of driver assistance and automated driving functions with realistic vehicle dynamics behavior. - Chassis & Vehicle Dynamics Control
Development and tuning of braking, steering, torque vectoring, and active suspension systems. - Vehicle Concepts & Variants
Rapid evaluation of conventional, electric, and hybrid vehicle concepts for handling, stability, and performance. - Realistic Function Development
Simulation of complex roads, driving maneuvers, and environmental conditions for safety‑relevant scenarios.
Validation and Virtual Homologation
Validated models are an essential prerequisite for reliable virtual homologation. In combination with validation tools in accordance with ISO 7401 and ISO 22140, ASM Vehicle Dynamics enables standardized and traceable virtual validation of ECU functions.
Support for OpenX formats
ModelDesk provides users with powerful editors for the efficient creation of roads and scenarios. In addition to proprietary road and scenario formats, ASM Vehicle Dynamics natively supports ASAM OpenDRIVE® and OpenSCENARIO®.
Technical Details
Vehicle Characteristics for ASM Vehicle Dynamics
For realistic vehicle simulation, the vehicle model is designed as a multibody system. The model consists of elements such as a drivetrain with elastic shafts, a table-based engine, two semi-empirical tire models, a nonlinear table-based vehicle suspension model with kinematics and compliance, a steering model, and aerodynamics. An environment with a road, maneuvers, and an open- and closed-loop driver is included as well. All parameters can be altered during run time. To simulate brake systems, models of a dual-circuit hydraulics system and a pneumatics system are available as add-ons.
