Sensing Proximity to Trailer Rollover: Theoretical and Experimental Analysis

This research is in regards to the development of an inexpensive anti-rollover system for use in the trailer axles of a heavy commercial truck. It includes the design and experimental results for a real-time rollover warning system to inform the driver prior to rollover or to initiate stability control algorithms in the vehicle. The developed system in this research uses suspension displacement, lateral acceleration, and wheel speed measurements. These are used to continuously update the calculation of centre of gravity (CG) height which is compared to the lateral acceleration to determine the proximity of rollover.
