Simulation of Driveability in Real-time 2009-01-1372
In this article a new approach for a combined optimization of performance, emissions, fuel consumption and driveability is presented. Traditionally the development of performance, emissions and consumption takes place on drivetrain testbeds and on chassis dynos. The development of driveability is done in vehicle tests very late in the development phase for which AVL-DRIVE™ is used by many OEMs for the objective evaluation of driveability.
The so-called “Vehicle Simulation Model” VSM is a framework for the simulation of driveability in real time. Its flexible model structure as well as the tight connection to AVL-DRIVE™ offers the possibility to integrate the optimization of driveability in earlier development steps and therefore neglect repeating loops in the development caused by e.g. not fulfilled driveability targets.
