Abstract: The problem considered in this paper is the optimisation of the gear-set of a race car in a virtual (software) environment. This task has been split into three sub-tasks: first, the maximum achievable speed (as a function of the local curvature radius) in every position of the circuit has been computed; then, the lap-time has been computed with an innovative forward–backward integration procedure of a simple and numerically efficient dynamic simulator; finally, using the lap-time computation algorithm, the best gear-set is obtained by a multi-dimensional optimisation procedure. All the results have been developed and tested on real data, and the gear-set optimiser has been implemented in a complete and stand-alone software package.
