Abstract
Method for controlling a refilling motor (2) that drives a hydraulic pump (4) that refills at least one pressure accumulator (8), this accumulator thereafter delivering the hydraulic pressure (P) to a hydraulic traction machine (20) of a hybrid vehicle, characterized in that it takes account both of the rate of discharge of the pressure accumulator (8) and of the time to start (Δi) the refilling motor (2) so as to manage this start in such a way that this accumulator more or less reaches its minimum operating pressure level (PI) at the end of this start (t1).
