AVL Approach

AVL creates added value through a combined approach of objective evaluation, accurate simulation, experienced engineers and the availability of high-end testing facilities.


Objective Evaluation Tools
The use of objective evaluation methods along the entire development process leads to comparable benchmarking results, easy target tracking and quality gate checking.
AVL-DRIVETM is used for evaluation of handling, ride comfort, driveability and performance.


Vehicle Dynamics simulation
The use of vehicle dynamic simulation predicts vehicle behavior precisely and enables early improvement of various driving attributes. AVL VSM™ Simulation Package:

  • Longitudinal, lateral & vertical vehicle behavior
  • Precise results through detailed vehicle modelling
  • Accurate limit handling simulation
  • Easy integration of active chassis systems


Huge engineering know-how
For the past few decades, AVL has gained comprehensive expertise in racing and vehicle dynamics engineering and has successfully proven this competence in numerous customer projects.
 

High-end testbeds
Dynamic development and testing of driveability, handling, performance and lap time is executed on virtual vehicle engine testbeds, dynamic powertrain dynos (2WD, 4WD) and the Hexapod driver-in-the-loop simulator.
