    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.

    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 method of guiding a vehicle to a region for initiating a parallel parking maneuver. A region of feasible starting locations for successfully performing a parallel parking maneuver is determined by a processor. A position of the vehicle relative to the region of feasible starting locations is determined. A determination is made whether the vehicle is in a zero heading position. The vehicle is guided along an initial target path by controlling a steering actuator until the vehicle is in a zero heading position relative to the road of travel in response to the vehicle is not in the zero heading position. A planned path is generated that includes two arc-shaped trajectories extending between the vehicle at the zero heading position and a position within the region of feasible starting locations as determined by the processor. The steering actuator is controlled to follow the planned path to the feasible region.

    摘要: A method and system may determine, in a vehicle, a desired path around an object based on a location of the object relative to the vehicle, relative speed, road parameters and one or more vehicle parameters. The method and system may calculate one or more vehicle control parameter values which minimize a predicted deviation from the desired vehicle path. The method and system may determine whether the one or more vehicle control parameter values would cause the vehicle to exceed one or more vehicle stability constraints. If the one or more vehicle control parameter values would cause the vehicle to exceed one or more vehicle stability constraints, the one or more vehicle control parameter values may be reduced to one or more vehicle control parameter values not causing the vehicle to exceed the one or more vehicle stability constraints. The method and system may output the one or more vehicle control parameter values to a vehicle automated control device.
