Hybrid-electric vehicles (HEVs) were designed to improve fueleconomy by using two propulsion sources a conventional internal combustion engine (ICE) and an electric machine that acts as an electric motor or generator (MG), depending on driving conditions. The MG lowers the demand placed on the ICE to save fuel and lower tailpipe emissions partly via optimized use of a smaller, more fuel-efficient ICE compared to the comparable conventional vehicle.
An environment corresponds to a single HEV car drived by a human from a point A to a point B, and from the point B to the point A. There are 43 episodes sampled at 1 second.
