Abstract
The present invention relates to a method and system for detecting a vehicle rollover or near-rollover event that may precede a rollover of a vehicle. The system comprises controller connected to at least one right and at least one left vehicle tire pressure sensor, performing the assessment of pressure signals on the basis of pressure characteristics corresponding to rollover or near-rollover events, and generating an output activation signal that determines the vehicle rollover or near-rollover event if said assessment is positive. The controller is preferably connected to at least one additional sensor and performs the additional assessment of this sensor signal on the basis of this signal characteristics corresponding to rollover or near-rollover events. The protection devices are activated sequentially, starting with the resetable protection devices, in dependence of estimated rollover confidence.
