摘要： An analytical methodology for the specification of progressive optimal compression damping of a damper of a suspension system to negotiate a multiplicity of severe events, yet provides very acceptable ride quality and handling during routine events. The damping response of the damper is optimized based upon a progressive optimal constrained events damping function derived from a low envelope curve incorporated with a predetermined damper force acting on the wheel center below a predetermined wheel center velocity, u1, based on ride and handling considerations for a given vehicle or vehicle model according to the prior art methodology, whereby the low envelope curve is constructed utilizing a one degree of freedom nonlinear mechanical system model or a quarter car nonlinear mechanical system model.

摘要： A system and method for estimating surface coefficient of friction in a vehicle system. The method includes providing a kinematics relationship between vehicle yaw-rate, vehicle speed, vehicle steering angle and vehicle front and rear axle side-slip angles that is accurate for all surface coefficient of frictions on which the vehicle may be traveling. The method defines a nonlinear function for the front and rear axle side-slip angles relating to front and rear lateral forces and coefficient of friction, and uses the nonlinear function in the kinematics relationship. The method also provides a linear relationship of the front and rear axle side-slip angles and the front and rear lateral forces using the kinematics relationship. The method determines that the vehicle dynamics have become nonlinear using the linear relationship and then estimates the surface coefficient of friction when the vehicle dynamics are nonlinear.

摘要： A vehicle includes wheels, force sensors adapted for a vertical force and lateral force of each wheel, an onboard device, and a controller. The controller calculates vehicle values using the vertical force and lateral force, compares the values to a corresponding threshold, and automatically deploys the device when each element value does not exceed a corresponding threshold. A method for determining when to deploy an airbag includes measuring a vertical and lateral force at each wheel, and measuring a yaw rate and roll angle. A lateral velocity is calculated using the lateral force, and a lift of each wheel is calculated using the vertical force. The roll angle, roll rate, and stopping time are processed to generate a point on a 3D rollover plane. A rollover energy rate is calculated, and the airbag deploys when the point, rollover energy rate, and lift do not exceed a threshold.

摘要： A method is provided for estimating vehicle velocity for a vehicle using a single-antenna global positioning system (GPS). An absolute speed and a course angle of the vehicle is measured using the single-antenna GPS. The yaw rates of the vehicle are measured independently of the GPS. An integrated yaw rate of the vehicle is calculated as a function of the measured yaw rates over a period of time. A yaw angle is determined as a function of a reference yaw angle and the integrated yaw rate. Aside slip angle is calculated as a function of the estimated yaw angle and the course angle provided by the GPS. The vehicle velocity is determined as a function of the absolute speed and the side slip angle. The vehicle velocity is provided to a vehicle dynamic control application.
