用于校准机动车中的加速度传感器的方法和装置
摘要：
本发明涉及一种用于校准一用于获知机动车（1）的纵向加速度的加速度传感器（5）的方法，其中，确定加速度传感器（5）的传感器模块的一个或多个传感器参数，利用传感器模块能从物理的传感器参量中获知机动车（1）的实际的纵向加速度，所述方法包括下列步骤：‑获知在驶过一测量路段期间的车辆速度的变化；‑借助于需校准的加速度传感器（5）获知在驶过该测量路段期间机动车（1）的纵向加速度的变化；‑获知在驶过该测量路段期间机动车（1）的高度位置的变化；以及‑基于在驶过该测量路段期间车辆速度的变化、机动车（1）的纵向加速度的变化以及机动车（1）的高度位置的变化，获知传感器模块的一个或多个传感器参数。
摘要（英）：

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.
