Abstract
The method according to the invention calls upon a rotary electric machine (1) comprising a drive member (3) and a transmission member (4) of the belt or chain type, collaborating with the drive member and with the combustion engine (2) in order to start or restart the combustion engine, a tensioner (6) being provided to press against one strand (7) of the transmission member that extends between the rotary electric machine and the combustion engine. According to the invention, in a first stage, the rotary electric machine (1) supplies a predetermined reduced torque in the direction of starting for a predetermined duration in order to tension the transmission member (4) and then, in a second stage, the rotary electric machine (1) supplies a predetermined optimum torque for rapidly turning over the combustion engine (2) and causing it to start.
