  • Patent number: 7788007
    Abstract: A system and method for providing a vehicle roll stability indicator that estimates the propensity for vehicle rollover. The system determines vehicle kinematics from vehicle sensors, such as roll rate, yaw rate, lateral acceleration, vehicle speed, etc. From these kinematic values, the system estimates a roll angle of the vehicle and a bank angle of the vehicle. From the estimated bank angle, the system provides a corrected roll angle. From the corrected roll angle, the system determines a roll energy of the vehicle and a roll energy rate of the vehicle. From the roll energy and the roll energy rate, the system calculates a roll stability indicator that defines the potential that the vehicle will tip-up or roll over. From the roll stability indicator, vehicle stability control systems can take suitable action.

Upon turning of the vehicle, if a parameter corresponding to the rolling behavior of the vehicle becomes higher than a control start criterion value set in advance, then roll-over suppressing control of suppressing rolling of the vehicle is started. Then, if the parameter becomes lower than a control end criterion value set in advance, then the roll-over suppressing control is ended. As the control end criterion value, a steady turning control end criterion value is used when the turning of the vehicle is steady turning, but when the turning of the vehicle is non-steady turning such as lane change turning, a non-steady turning control end criterion value set to a value lower than that of the steady turning control end criterion value is used.

  • Patent number: 7512461
    Abstract: A vehicle rollover sensing apparatus and method are provided for predicting a future roll angle and an overturn condition of a vehicle. The apparatus includes an angular accelerometer for sensing angular acceleration of the vehicle and producing an output signal indicative thereof. A first integrator integrates the sensed angular acceleration signal and produces an angular rate. A second integrator integrates the angular rate and generates a current roll angle. A predictor predicts a future roll angle as a function of the sensed angular acceleration, angular rate, and current roll angle. A comparator compares the predicted future roll angle to a threshold value. The apparatus generates a vehicle overturn condition signal based on said comparison, and signals deployment of restraint devices.

  • Patent number: 7460008
    Abstract: A tilt switch apparatus has an acceleration sensor or sensors, a temperature sensor, an auto-zero function or switch, a central processing unit (CPU), a memory, a communication port, a current source circuit, a current sink circuit, an alarm output, an input power connection, a power conditioning circuit, a housing, an optional visual tilt, zero, and power indicator. The CPU monitors the temperature sensor and applies correction factors to the acceleration sensor reading to adjust for predetermined variations due to changes in temperature. The tilt angle is determined using the temperature corrected reading of acceleration due to gravity. The alarm output is generated when the measured tilt angle relative to an established reference plane exceeds a programmed threshold angle for greater than a programmed amount of time. The alarm output is discontinued when the tilt angle is reduced below the threshold angle by a programmed hysteresis angle for greater than a programmed amount of time.

  • Patent number: 7443288
    Abstract: A tire and suspension monitoring and warning system consisting of a set of multi-function sensors that monitor and warn of a failure mode. The system monitors and warns for tire imbalance, tire tread wear, and shock absorbers for a tire attached to a vehicle. The monitoring and warning system includes one axial, radial, and lateral acceleration measurement of the wheel to provide acceleration signal sample power. For tire imbalance, signal sample power in the second harmonic of the tire rotational frequency is compared to that of the first harmonic. For tire tread wear, average signal sample power within a second frequency range is compared to a previously stored baseline value. For shock absorber performance, a sum of all frequency components in a second predetermined frequency range is compared to a baseline value.

  • Patent number: 7422087
    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.

  • Patent number: 7412314
    Abstract: Impending rollover events are detected by recognizing a plow phase increase in lateral acceleration, coupled with a significant trip phase roll rate. The plow phase increase is recognized by modeling a typical soil trip lateral acceleration characteristic and computing a cross-correlation between the measured lateral acceleration and the modeled acceleration. The correlation is compared to a threshold that varies with the measured roll rate to reliably discriminate rollover events from near-rollover events while enabling timely deployment of suitable occupant restraints.
