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.

L'invention concerne un système utilisant de multiples capteurs de dévers montés sur le châssis d'un véhicule et son système de suspension afin de détecter une accélération latérale et un transfert de charge latéral. Le système utilise ces mesures afin de déterminer un rapport de transfert de charge latéral indiquant un moment de roulis maximum. Les mesures des capteurs de dévers sont également utilisées pour calculer un centre effectif de hauteur de gravité. Un affichage couplé au système fournit à l'utilisateur du véhicule une sortie relative au transfert de charge et au centre effectif de hauteur de gravité. L'affichage permet à l'utilisateur du véhicule de comprendre plus complètement la nature de la charge du véhicule et lui permet par conséquent d'éviter des situations susceptibles de conduire à un accident du véhicule par retournement.
