Abstract: The micro-hybrid system for a transport vehicle comprises a rotary electric machine (10) suitable for being coupled mechanically to an engine (5) of the vehicle, an AC-to-DC converter (11), a DC-to-DC converter (13), first (12) and second (2) electrical energy reservoirs suitable for storing an electrical energy produced by the rotary machine and for restoring the latter for consumer devices equipping the vehicle, and control means (14) for controlling the operation of the micro-hybrid system. In accordance with the invention, the control means (14) comprise piloting means (140) suitable for autonomously piloting the operating modes of the micro-hybrid system according to a plurality of strategies according to at least their own knowledge of an internal state of the micro-hybrid system and of a state of the vehicle.

Abstract: A switching unit for a device for managing the supply to a network of power-consuming elements for a motor vehicle, said management device including: a main network (Rp), a main energy storage element (Bp) which is intended to supply the main network (Rp), a secondary network (Rs), and a secondary energy storage element (Ucap) which is intended to supply the secondary network (Rs). According to the invention, the unit is intended to connect the secondary network (Rs) electrically with the secondary energy storage element (Ucap) when the vehicle is in a parking mode. The secondary energy storage element (Ucap) comprises a super-capacitor (Ucap) and includes means (D0, Rp) for pre-charging the secondary energy storage element (Ucap). The invention is suitable for motor vehicles.
