| 20090187324 | Vehicle Stability Control System and Method - A vehicle stability control system comprises a 5-sensor cluster and a stability controller configured to communicate with the 5-sensor cluster and receive signals corresponding to a lateral acceleration, a longitudinal acceleration, a yaw rate, a roll rate, and a pitch rate from the 5-sensor cluster. The stability controller can also be configured to determine a braking amount or a throttle amount to maintain vehicle stability. The system also comprises a brake controller configured to communicate with the stability controller and receive a braking request from the stability controller, and a throttle controller configured to communicate with the stability controller and receive a throttle request from the stability controller.

| 20090271073 | STABILITY CONTROL SYSTEM WITH BODY-FORCE-DISTURBANCE HEADING CORRECTION - A yaw stability control system for a vehicle detects and eliminates the vehicle yaw angle resulting from a body-force-disturbance and returns the vehicle to a pre disturbance heading. A yaw rate module generates a signal indicative of the vehicle yaw rate error. A yaw angle error module is triggered in response to a body-force-disturbance being detected by a body-force-disturbance detection unit, and performs integrations of the yaw rate signals to calculate a yaw angle error in order to obtain a correction of the vehicle yaw angle resulting from the body-force-disturbance. A yaw control module uses the yaw angle error in combination with the yaw rate error for a limited time period to generate yaw control signals that are sent to the vehicle brakes and/or active steering system for performing vehicle yaw stability control operations a signal to perform a body-force-disturbance yaw stability control operation for. | 10-29-2009 |
