摘要： A system and method for estimating vehicle roll rate and roll angle. The system includes a suspension deflection sensor provided at each wheel of the vehicle that provides suspension measurement signals indicative of the roll of the vehicle. The system also includes a roll rate estimator that uses the suspension measurement signals and an estimated tire deflection of the wheels to provide a roll rate estimation signal. The system also includes a vehicle roll angle and a roll rate estimator that uses the roll rate estimation signal and a dynamic model to estimate the roll angle and refine the roll rate. The roll rate estimator calculates the roll rate one way if none of the vehicle wheels are off of the ground and calculates it another way if any of the wheels are off of the ground.

摘要： A system and method for providing a vehicle roll stability indicator that dynamically estimates the probability for vehicle rollover. The system determines vehicle kinematics from various vehicle sensors. From these kinematic values, the system estimates a roll angle of the vehicle and a bank angle of the vehicle. The estimated bank angle is used to correct the roll angle. The system determines a roll energy of the vehicle and a roll energy rate of the vehicle from the corrected roll angle. The system also calculates a tire lateral load transfer of the relative forces on the vehicle tires, and the duration that any of the tires have been off of the ground. From the roll energy, the roll energy rate, the tire lateral load transfer and the wheel airborne duration, the system calculates the roll stability indicator.

摘要： A system and method for estimating vehicle side-slip velocity that includes measuring the lateral acceleration of the vehicle, measuring the yaw rate of the vehicle, measuring the longitudinal speed of the vehicle and measuring the steering angle of the vehicle. The measured longitudinal speed is corrected to provide a true longitudinal speed using a filter factor based on the vehicle-dependent parameters and a steering angle. A constant is defined based on the measured longitudinal speed and a function is defined based on the combination of the vehicle-dependent parameters and the lateral acceleration. Side-slip acceleration is calculated using the measured lateral acceleration, the true longitudinal speed, the yaw rate, the constant and the function.

摘要： 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.
