Abstract: Powertrain electrification is one of the promising ways to reduce greenhouse emissions from fossil fuels. Also, the development of autonomous driving systems for vehicles is gaining a lot of interest in the scientific community. The convergence of electric powertrain and autonomous driving will open new opportunities to improve significantly the energy efficiency of the vehicle (battery vehicle) whilst decreasing road accidents. However, these two topics (powertrain electrification and autonomous driving) are still discussed separately. To accelerate their convergence, a unified modelling and system optimization need to be carried out.

Nowadays and without autonomous driving, some significant progress has been done in order to optimize the use of onboard electric energy for short trips (i.e. commuting trips). However, the global energy efficiency and the battery lifespan preservation need more investigations over a long trip (i.e. the trip length exceeds the available vehicle autonomy). Indeed, the overall trip duration is extended with the battery charging time, and obviously, letting the battery to be depleted heavily (high values of depth-of-discharge) before stopping for charging can help to reduce this trip duration. But the battery lifespan is negatively affected by these depth-of-discharges. Stopping often in order to charge the battery and prevent a high depth-of-discharge will potentially increase the overall trip duration. Therefore, a trade-off must be found between preserving the battery lifespan and keeping reasonable the trip duration whilst improving globally the efficiency.

This technical tutorial will start by introducing some well-known models for autonomous driving and an electric vehicle (battery vehicle). Then, using the convex optimization framework, we will discuss a method to use autonomous driving capability to increase energy efficiency, for urban and highway driving conditions (with and without traffic).
