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

System and method for detecting roll rate sensor fault
Hongtei Eric Tseng,Li Xu +1 more
TL;DR: In this paper, a roll rate sensor is positioned within the housing and generates a sensor signal corresponding to a roll angular motion of the sensor housing, and the controller sets a fault flag in response to the fault condition indicated for a predetermined time during which no double wheel lift occurs.

Systems and methods for controlling a vehicle-occupant protecting apparatus
Tomoki Nagao,Motomi Iyoda +1 more
TL;DR: In this paper, a vehicle-occupant protecting apparatus is provided on a vehicle such that the apparatus is controlled upon determination that the vehicle has had a rollover motion, the control system including a first detector that determines whether the vehicle had crashed, a second detector that determined whether a vehicle had had a rolling motion, and an invalidating device that invalidated the determination by the second detector.
