Motor vehicles weight estimating method, involves analyzing error on variation of vehicle weight relative to reference weight, error on declivity of surface on which vehicle is engaged and model error to calculate vehicle acceleration

摘要

The method involves analyzing errors including an error on variation of weight of a motor vehicle relative to a reference weight, an error on declivity of surface on which the vehicle is engaged and an error of model. Longitudinal acceleration of the vehicle is calculated using the analysis of the errors to estimate the weight of the vehicle by a recursive least squares algorithm. The declivity is provided by a slope sensor. An independent claim is also included for a device of estimating a total weight of a motor vehicle.
