Driveability Simulation

Advanced simulation to balance driving feeling in early development phases

Increasingly stringent regulatory requirements for emissions and energy efficiency are forcing automakers to implement a variety of new technologies in new vehicles. At the same time, customer demands for a superior driving experience, driving performance and comfort – commonly referred to as driveability – are increasing.

Whether it’s conventional, hybrid or battery electric vehicles – driveability massively influences the driving experience. This is a big differentiator for OEMs.
 

Objective Driveability Development


At AVL we have spent many years assessing those vehicle characteristics that trigger an emotional response in the driver. From acoustics to acceleration and braking, we have created a database of traits that express how a vehicle feels to the driver.

Driveability might be expressed by the driver with words such as “sporty”, “engaging”, “agile” and “comfortable”. Thanks to our benchmarking program we understand the precise vehicle behaviors that these descriptions represent. That means we can support OEMs in the development of cars with specific driveability traits, and with our advanced simulation tools, we make this task even simpler.

 

Virtual Vehicle Prototypes


Our unique simulation-based development tool, AVL VSM™ (Vehicle Simulation Model), allows engineers to reliably and precisely predict end user-relevant driving characteristics. It optimizes acceleration feeling, full load shaping and tip-in/tip-out behavior to meet the driver’s subjective expectation.

AVL VSM enables the virtual development and testing of driveability characteristics. Comprehensive, scalable, precise and consistent, it allows multiple vehicle attributes, such as driveability, performance, and emissions, to be balanced with minimal trade-offs.

We do this early in the development process by combining the objective assessment tool AVL-DRIVE™ with virtual prototypes. This take place long before any real prototype vehicle has left the workshop, even faster than in real time, promoting a right-first-time approach.
