Driveability Engineering for Commercial Vehicles

The system captures various driveability related sensor and CAN bus signals, such as longitudinal acceleration, engine speed, vehicle speed, pedal positions and vibrations. These input quantities are collected by the DMU2 (DRIVE Main Unit) and passed on to the AVL-DRIVE software for further processing and analysis. More than 100 different driving modes (engine, transmission and chassis related) are detected automatically and more than 800 driveability related criteria are rated in real-time. The assessment is based on measured/calculated parameter values and is done by means of a DRIVE Rating (DR) from 1 to 10. Visualization and automatic report creation is supported by AVL-DRIVETM to shorten documentation time.

Market Requirements

  • Increase efficiency during the development process
  • Improvement of vehicle quality for  higher customer satisfaction
  • Develop OEM specific D.N.A.

Customer Benefits

  • 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 OEM's and transmission manufacturers use AVL-DRIVE™ and VSM for quality assurance of driveability in engine and powertrain development projects.


Procedures for the assessment of the highly subjective perception of the driver 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.

  • Supporting the calibration process for optimization of driveability
  • Specification of target driveability
  • Reduction of after-market costs caused by driveability quality issues

AVL-DRIVE™  for commercial vehicles is available for various vehicle classes (light-duty truck, medium and heavy-duty truck, buses and coaches  and the following transmission types: 

  • MT (manual transmission)
  • AMT (automated manual transmission)
  • AT (automatic transmission)


Technical Data

The AVL-DRIVE measurement system is designed for the objective real-time assessment and quality control of driveability based on the driver's perception.
