Driveability Engineering and Simulation

AVL-DRIVE™ - The Objective Tool for Driveability Assessment and Development - in co-simulation with VSM "Vehicle Simulation Model" - a mathematical model for the simulation of driveability in real-time - extends the capability of objective driveability evaluation from road to lab.

AVL Approach

Procedures for the assessment of the highly subjective driver perception have been elaborated to define the evaluation method and formulas. Experiences acquired from internal and external vehicle benchmarks and driveability development projects are continually incorporated in the AVL-DRIVE™ software.
  • Frontloading of driveability assessment with AVL-DRIVE™ and VSM reduces number of development loops and prototypes
  • Closed loop process for automatic optimization of driveability
  • Specification of target driveability
  • Reduction of after-market costs caused by driveability quality issues
AVL-DRIVE™ is available for various vehicle types (e.g. passenger car, bus, truck, tractor) and vehicle classes (e.g. small, large, sportive, SUV, light/heavy-duty truck) and the following transmission types: 
  • MT (manual transmission)
  • AMT (automated manual transmission)
  • AT (automatic transmission)
  • DCT (double clutch transmission)
  • CVT (continuously variable transmission)
 
Besides conventional combustion engines, hybrid powertrain configurations and electric vehicles are also supported.

Benefits at a Glance

  • Assurance of high driveability quality level
  • Reproducible driveability assessment based on measured physical values
  • Combined operation mode based driveability, performance and fuel consumption assessment
  • AVL-DRIVE™ for all phases of the development process, from pure math to on-road vehicle testing
  • Common language in driveability development between development areas and within the supply chain
  • Real-time assessment provides instant feedback of driveability quality issues and encourages target driven development
  • Early detection of driveability deficiencies on test bed/simulation even before a prototype vehicle is available (front loading)
  • Automatic optimization of driveability (in combination with a closed loop process incorporating the DOE-Tool CAMEO)
  • Reduction of number of prototype vehicles ("From Road to Rig to Pure Math")
  • Reduction of development time
  • Easy integration in customer environment with interfaces to 3rd party measurement systems (ETAS/INCA, ATI/VISION)

With more than 10 years of experience in driveability evaluation and simulation, a lot of OEMs and transmission manufacturers use AVL-DRIVE™ and VSM for the quality assurance of driveability in engine and powertrain development projects.
