Proposal

Main paper can be found here.

  • a convex model of battery and transmission system for electric race cars
  • support for modelling single gear ratio (SR) and CVT types of transmissions
  • a computationally efficient optimization framework for energy management

Summary

  • authors model the vehicle dynamics, transmission, electric motor and battery pack via classical mechanics and control systems
  • the optimization problem is posed as minimizing the laptime, iteratively
  • optimization solver used is ECOS. They run this iterative optimizer 3 times in order to achieve robustness.
  • (ECOS is a second order cone programming solver)
  • discretization along the track is done with a $$\Delta s$$ of 10m.
  • on a mid-range Intel CPU, they achieve an overall runtime of 1min
