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

A method of controlling a supercapacitor energy storage unit (), included in a motor vehicle micro-hybrid system, is disclosed. The storage unit is suitable for performing the functions of an alternator, starter and automatic stop-restart of the vehicle heat engine, regenerative braking and torque assistance. The energy storage unit () is a plurality of supercapacitor elementary cells connected in series (Cto C) and capable of delivering information (Vmax, Temp and DeltaV) on its internal status. The method includes various stages of: comparing a maximum elementary voltage (Vmax) with a first voltage threshold (Vmax); comparing a temperature (Temp) with at least one temperature threshold (ST=55&#xb0; C., ST=65&#xb0; C. and ST=70&#xb0; C.); and, deciding on limitations of the availability of functions of the unit when the (Vmax) information reaches threshold (Vmax) for a predetermined duration (T) and/or when the (Temp) information reaches the temperature threshold (ST=55&#xb0; C., ST=65&#xb0; C. and ST=70&#xb0; C.).
