  • Publication number: 20240149861
    Abstract: A method detects a vehicle overweight state for a vehicle equipped with a power unit including a traction battery. The method selects a number of vehicle acceleration phases. The method includes, for each selected acceleration phase: calculating a mean value of a differential force equal to a value of the traction loads of the unit from which there are subtracted the value of the acceleration resultant force and the value of the sum of the resistive loads experienced by the vehicle, calculating a statistical value based on the calculated mean values of the differential force, and comparing the statistical value against a vehicle overweight threshold value. The vehicle is in an overweight state if the statistical value is higher than the threshold value.
