Stochastic Methods for Handling Uncertainties in Automotive Applications

Project Description

It is no secret that the market share of electric vehicles is growing rapidly. The next generation of electric vehicles will have faster charging capabilities, have greater range and so on. In order to achieve those goals, new electric components are being developed. And to test those new electric components, high-performance test systems are needed. With high-performance we don’t just mean cutting-edge hardware, but also advanced control concepts, which allow for enhanced testing capabilities.

Project Overview Wasserburger

State of the Art Calibration

  • typical automotive calibration workflows do not account for varying operation conditions, different drive cycles and other uncertainties
  • higher than expected consumption and emissions
  • excessive real-world testing for real driving emissions (RDE) and safety in advanced driver assistance system (ADAS)

Robustness under operating un-certainty can be achieved by using stochastic optimisation methods, instead of traditional formulations. The solution of these stochastic problems enables safe and low-emission operation of powertrains under uncertain and unpredictable conditions such as those encountered in real-world driving. This is also highly relevant for the calibration of combustion engines due to current real driving emissions (RDE) regulations. In order to calibrate a powertrain for general real-world RDE drive cycles, it is important to consider the possible variability of real-world driving in the powertrain opti-misation.

For that purpose, concepts for generating realistic RDE drive cycles, which fulfil all regulatory constraints as required for real-world testing, were investigated. The goal is to generate a large number of driving cycles that cover the operating con-ditions occurring in reality (and also their statistical distribution) as closely as possible. Taking uncertainties into consideration during the development and calibration of pow-ertrain systems, the expensive real-world testing efforts can thus be reduced considerably.
