  • Patent number: 8475328
    Abstract: The micro-hybrid system for a transport vehicle comprises a rotary electric machine suitable for being coupled mechanically to an engine of the vehicle, an AC-to-DC converter, a DC-to-DC converter, first and second electrical energy reservoirs suitable for storing an electrical energy produced by the rotary machine and for returning the electrical energy to consumer devices equipping the vehicle, and a controller for controlling the operation of the micro-hybrid system. The controller comprises piloting strategies module suitable for autonomously piloting the operating modes of the micro-hybrid system according to a plurality of strategies depending on information provided to said piloting means regarding an internal state of the micro-hybrid system and of a state of the vehicle.

  • Publication number: 20100298088
    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.
