A method for controlling regenerative braking of an automobile micro-hybrid system is disclosed. The system includes at least a rotary electrical machine and an electrochemical battery. The method includes a step, when the electrochemical battery has a first predetermined energy state, which corresponds to an initial optimum charging state, of commanding a reduction of the first energy state, to a second energy state corresponding to an intermediate charging state, so as to make a charging capacity available in the electrochemical battery during a subsequent opportunity for recovery of electrical energy during, for example, a braking phase of the vehicle.

Method and device for controlling micro-hybrid system with regenerative braking for motor vehicle

Described is a micro-hybrid system for an automobile including: 1) a rotating electrical machine (i.e., a starter/alternator); 2) at least one power converter connectable to an electricity distribution network of the automobile, this network including a power storage unit; and, 3) a control circuit capable of controlling the power converter to provide a power supply current to the electricity distribution network. The system additionally provides a device associated with the control circuit for controlling, during a change of state between the states of providing and not providing the power supply current to the electricity distribution network, an at least partially gradual variation in a charge voltage generated by the power converter so as to obtain a corresponding gradual variation in a network voltage of the electricity distribution network from a first network voltage value to a second network voltage value, a duration of the variation between the first and second network voltage values being predetermined so as to eliminate a negative effect or consequences (surges, dimming of lights, etc.) of a state change on the electronic environment of the micro-hybrid system.
