TLDR
In this article, a system uses multiple tilt sensors mounted to the vehicle frame and the vehicle suspension system to detect lateral acceleration and lateral load transfer, and a display coupled to the system provides the vehicle operator with a read out of the load transfer ratio and effective center of gravity height.Abstract:
A system uses multiple tilt sensors mounted to the vehicle frame and the vehicle suspension system to detect lateral acceleration and lateral load transfer. The system uses these measurements to determine a lateral load transfer ratio indicative of an actual roll moment compared to a maximum roll moment. The measurements from the tilt sensors are also used to calculate an effective center of gravity height. A display coupled to the system provides the vehicle operator with a read out of the load transfer ratio and effective center of gravity height. The display enables the vehicle operator to more completely understand the nature of the vehicle load and thereby allow the vehicle operator to avoid conditions likely to lead to a vehicle rollover accident.read more

TL;DR: In this article, a method for estimating a location of a center of gravity (CG) of a sprung mass of a vehicle includes steps of determining whether the vehicle is stationary or moving, calculating estimated x and y coordinates of the CG; storing the estimated coordinates in memory; and repeating steps a)-c) until the vehicle was no longer stationary.
Patent
Vehicle rollover detection and prevention system
TL;DR: In this article, an accelerometer and gyroscope are used to sense lateral yaw rate excursions of the vehicle, enabling the processor to correlate these excursions at a given speed with the lateral G forces produced while the vehicle is turning.
