Title: AUTONOMOUS METHOD AND DEVICE FOR DETERMINING A TRIM OF A MOTOR VEHICLE
Abstract:
The invention relates to a device (1) comprising a measuring unit (6) comprising at least two accelerometers (A1, A2) respectively measuring a longitudinal acceleration and a vertical acceleration of the motor vehicle, the measuring unit (6) being designed to measure a plurality of successive measurement sets, each measurement set comprising at least one longitudinal acceleration and a vertical acceleration, and a computing unit (7) for calculating the trim of the motor vehicle (2), exclusively by means of measurements carried out by the measuring unit (6), the computing unit (7) comprising a first element (9) for implementing a linear regression by means of a plurality of measurement sets which each comprise at least one vertical acceleration and a longitudinal acceleration, in order to determine a plurality of proportionality coefficients, and a second element (10) for determining the trim on the basis of said proportionality coefficients.
