Accelerometer calibration

The invention relates to a calibration method for a system with at least two accelerometers (5), comprising the steps of arranging said accelerometers fixed on a vehicle (1), connecting said accelerometers (5) to a control unit and providing said vehicle (1) on a reference plane (11). The reference plane (11) has a known propagation angle to be used as a reference relative to which an offset value of each accelerometer (5) is established. Said offset value of each accelerometer is stored in said control unit. The invention also relates to a calibrated accelerometer system and a vehicle (1) provided with said system.
