Abstract
Device for regulating the source of electric energy on a hybrid electric vehicle comprising at least an electric motor for driving the driving wheels of the vehicle and supplied with current by said source of energy and a generating set comprising a heat engine with which there is associated a current generator supplying current to said source of electric energy. This device comprises a circuit for determining the state of charge of the source of electric energy, a circuit for controlling the excitation winding of the generator of the generating set in accordance with the state of charge of said source, and a logic circuit for operating and stopping the heat engine and controlled by said circuit determining the state of charge of said source of electric energy.
