Abstract
A control module for a vehicle system has: a lateral acceleration sensor for measuring a lateral acceleration and outputting a lateral acceleration measurement signal, a yaw rate sensor for detecting a yaw rate and outputting a yaw rate measurement signal, and a central control device for receiving the yaw rate measurement signal and the lateral acceleration measurement signal and determining a lateral acceleration of the vehicle at its center-of-gravity. The central control device determines the center-of-gravity lateral acceleration from a sensor distance of the lateral acceleration sensor from the vehicle center-of-gravity and the yaw rate measurement signal, forming a derivative over time. The central control device filters the yaw rate measurement signal with a low-pass filter and subsequently forms a derivative over time and determines the sensor distance on an up-to-date basis.
