Shift Schedule Optimization of a Dual Clutch Transmission

In this webinar we will demonstrate how to automatically tune the shift schedule for an automotive transmission using optimization algorithms.  Using a dynamic model of a dual-clutch transmission that uses measured data to estimate fuel economy, optimization algorithms are used to tune the transmission shift schedule to maximize fuel economy.

This webinar will include demonstrations and explanations to show you how to:

  • Create a vehicle model that is useful for control design, optimization studies, and HIL
  • Import measurement data to estimate fuel economy
  • Tune abstracted models to match simulation results from detailed models  
  • Use parallel computing to accelerate parameter sweeps and optimization studies
  • Find the global minimum for complex optimization problems

Tight vehicle emission regulations and high fuel prices have intensified the demand for fuel-efficient cars.  Tuning the transmission shift schedule is an important part of improving fuel economy, but since the shift schedule has many parameters, manual tuning of these values is a tedious option that will only find the optimal values by luck.  Solving the problem using simulation, optimization algorithms, and parallel computing can ensure that a truly optimal shift schedule is found.
