    摘要: A method is provided for calibrating an acceleration sensor for ascertaining a longitudinal acceleration of a motor vehicle. One or multiple sensor parameter(s) of a sensor model of the acceleration sensor is/are determined, via which the actual longitudinal acceleration of the motor vehicle is ascertainable from a physical sensor variable. The method includes the following steps: ascertaining a change in a vehicle speed during travel over a measuring section; ascertaining a change in the longitudinal acceleration of the motor vehicle during travel over the measuring section with the aid of the acceleration sensor to be calibrated; ascertaining a change in the height position of the motor vehicle during travel over the measuring section; and ascertaining the one or the multiple sensor parameter(s) of the sensor model based on the change in the vehicle speed, the change in the longitudinal acceleration of the motor vehicle, and the change in the height position of the motor vehicle during travel over the measuring section.
