Reduced order parameter identification for vehicle rollover control system
First Claim
Patent Images
1. A method of protecting against rollover in a motor vehicle, the method comprising:
- detecting a lateral acceleration of the motor vehicle;
detecting a roll rate of the motor vehicle;
estimating a mass distribution parameter;
generating a revised mass distribution parameter;
generating a tuned mass distribution parameter based on the lateral acceleration, the roll rate, and a comparison between the mass distribution parameter and the revised mass distribution parameter; and
introducing the tuned mass distribution parameter to a rollover stability control system of the motor vehicle.

Abstract
A system that detects a lateral acceleration and roll rate of the vehicle and estimates a mass distribution parameter. The system then generates a tuned mass distribution parameter that is based on the the lateral acceleration, the roll rate, and the mass distribution parameter and introduces the tuned mass distribution parameter to a rollover stability control system.

5. A system of protecting against rollover in a vehicle, comprising:
-
a sensor which measures a lateral acceleration of the vehicle; a second sensor which measures a roll rate of the vehicle; a multiplier which multiplies an estimated mass distribution parameter with the lateral acceleration to define an estimated roll rate; and a comparator which receives information regarding the roll rate, the estimated roll rate, and the estimated mass distribution parameter and generates a tuned mass distribution parameter that is transmitted to a rollover stability control system of the vehicle. - View Dependent Claims (6, 7, 8)
