Power train's energy managing method for e.g. electric/heat hybrid vehicle, involves making decision to ignite/extinguish engine based on criteria and gain, where criteria is determined to extend usage of storage unit and to stop engine

摘要

The method involves determining a fuel consumption gain, of a heat engine, in real time, independent of other energy sources external to the engine, from a difference between a consumption of an ignited heat engine and an equivalent consumption of an extinguished heat engine. Decision is made to ignite or extinguish the engine based on a criteria and the consumption gain, where the criteria depends on a restoration level of an electrical energy restoration unit and is determined in a manner to extend the usage of an electrical energy storage unit e.g. battery, and to stop the engine.
