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.
Claims8
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.
4 more elements
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.
