The battle against global warming and air pollution drive the legislation framework to push on more strict regulations. Nevertheless, OEMs must not refrain from facing those challenges, following increasingly ambitious targets in terms of efficiency, performances and costs. What is proposed in this work is the set-up of a gear shifting strategy that allow to fulfill the driver request, also in real driving conditions, and at the same time obtain a fuel economy improvement. As a matter of fact, with a gear shifting it is possible to operate a load point shifting, both for combustion engine and electric machine, and let the machines work in more efficient load points.
