Abstract: Disclosed is a method of improving the recognition of a tire pressure loss in a tire pressure monitoring system in which at least one reference value (A) is formed on the basis of signals representing the rotational speeds of several vehicle wheels. A pressure loss is concluded by comparing a currently determined reference value with at least one reference value if the currently determined reference value exceeds or falls short of a predefined value. A noise analysis of the reference value(s) (101) is executed and at least one threshold value (T, S) is adjusted (108) based on the result of the noise analysis (102).

Abstract: The present invention is directed to a system for determining lift-off or wheel departure of one or more wheels associated with a vehicle from a road. The system includes a sensor that measures the wheel speed of at least one wheel, and a controller that calculates the resonance frequency of the at least one wheel, calculates variations in the resonance frequency, compares the variations with a threshold, and indicates lift-off of the wheel from the road if the variations exceed a threshold.

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.

Abstract: The present invention features a system and method for estimating body states of a vehicle. The system includes at least two sensors mounted to the vehicle. The sensors generate measured vehicle state signals corresponding to the dynamics of the vehicle. A signal adjuster transforms the measured vehicle states from a sensor coordinate system to a body coordinate system associated with the vehicle. A filter receives the transformed measured vehicle states from the signal adjuster and processes the measured signals into state estimates of the vehicle, such as, for example, the lateral velocity, yaw rate, roll angle, and roll rate of the vehicle.

Abstract: A system and method protects against rollover in a vehicle by employing an array of linear acceleration sensors. A control module includes, among other things, a model of the vehicle dynamics and a model of the array of sensors. A state vector is estimated based on the detected accelerations, the model of the vehicle dynamics and the model of the sensors. A control signal is generated based on the state vector, and the roll moment of the vehicle is reduced based on the control signal.
