METHOD FOR CONTROLLING A POWER TRAIN AND CORRESPONDING SYSTEM

摘要

A method for controlling a power train and corresponding system. A method for controlling a power train equipping a motor vehicle and comprising an electric motor provided with a rotor and a stator, said method comprising the regulation of the currents of the rotor and the stator delivering control signals to the electric motor, said currents to be regulated and said control signals being expressed in a rotating reference system and comprising a plurality of axes. The method includes a measurement of the values of the currents of the rotor and the stator, a transformation of said measurements into said rotating reference system, a determination of minimum and maximum limits for each of the currents on the basis of said control signals, and a comparison of the measured signals with said minimum and maximum limits.

1. A method for controlling a power train equipping a motor vehicle and comprising an electric motor equipped with a rotor and a stator, said method comprising a regulation of the currents of the rotor and the stator conveying control signals to the electric motor, said currents to be regulated and said control signals being expressed in a rotating frame of reference comprising a plurality of axes,
characterized in that it comprises a measurement of the values of the currents of the rotor and the stator, a transformation of these measurements into said rotating frame of reference, a determination of minimum and maximum bounds for each of the currents as a function of said control signals, and a comparison of the measured signals with said minimum and maximum bounds.
