Method and system for detecting a vehicle rollover
First Claim
1. A method of detecting a vehicle rollover comprising the steps of(a) measuring a set of input signals including at least a vehicle velocity, a vehicle steering angle, a vehicle lateral acceleration, and a vehicle roll rate;
- (b) integrating the vehicle roll rate to obtain a vehicle roll angle increment;
(c) determining a vehicle state on the basis of the input signals;
(d) determining a vehicle estimated lateral acceleration based upon the vehicle state, the vehicle lateral acceleration, and a centrifugal acceleration;
(e) determining a vehicle estimated roll angle on the basis of at least the vehicle roll angle increment, the vehicle estimated lateral acceleration and the vehicle state; and
(f) generating an output activation signal determining a possibility of rollover of the vehicle, as a function of at least;
the vehicle estimated roll angle and the vehicle roll rate.

Abstract
The present invention relates to a method and system for detecting a vehicle rollover or dangerous situations that may precede a rollover of a vehicle. The method comprises the steps of (a) measuring the set of input signals including at least vehicle velocity, vehicle steering angle, vehicle lateral acceleration, and vehicle roll rate; (b) integrating the vehicle roll rate to obtain the vehicle roll angle increment; (c) determining the vehicle state on the basis of the input signals; (d) determining the vehicle estimated lateral acceleration, corresponding to the vehicle true roll angle, on the basis of at least the vehicle state, vehicle lateral acceleration and the centrifugal acceleration; (e) determining the vehicle estimated roll angle on the basis of at least the vehicle roll angle increment, the vehicle estimated lateral acceleration and the vehicle state; and (f) generating an output activation signal determining a possibility of rollover of the vehicle, as a function of at least: vehicle estimated roll angle and the vehicle roll rate.
