摘要： A method controls an electric drive system of a vehicle including an electric drive motor, a drive battery, and a drive inverter. The method includes detecting that a measurement of an insulation resistance between the battery and a chassis of the vehicle is below a preset threshold, detecting a closed state of relays connecting the battery to the inverter, and following the detecting the measurement and the detecting the closed state, activating a cooling fan of the electric drive motor until detecting that a measurement of the insulation resistance is above the preset threshold, within a limit of a first preset duration.
