Control Module for a Vehicle System, the Vehicle System and a Vehicle Having this Vehicle System
First Claim
1. A control module for a vehicle system, the control module comprising:
- a lateral acceleration sensor to measure a lateral acceleration of the vehicle and output a lateral acceleration measuring signal;
a yaw rate sensor to detect a yaw rate of the vehicle and output a yaw rate measuring signal; and
a central control unit configured to record the yaw rate measuring signal and the lateral acceleration measuring signal, filter the yaw rate measuring signal using a low-pass filter, form a time derivative, substantially instantaneously determine a sensor distance of the lateral acceleration sensor from the center of gravity of the vehicle, and determine a center of gravity lateral acceleration of the vehicle in the center of gravity of the vehicle based at least in part on thesensor distance and the filtered yaw rate measuring signal.

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.
