    摘要: A method for temperature compensating an air spring of an air spring suspension of a motor vehicle after engine shut-off. A desired trim height is obtained. At engine shut-off, the ambient temperature is measured and the temperature of air in the air spring determined. After a wait time (for loading/unloading), a start trim height is measured. A predicted trim height is determined for when the air in the air spring is at the ambient temperature. Finally, the volume of the air in the air spring is selectively adjusted so that when the air in the air spring arrives at the ambient temperature, the trim height will be about the desired trim height.

    摘要: A system and method for estimating vehicle lateral velocity. The method uses a kinematic estimator constructed as a closed-loop Leunberger observer. The kinematic estimator is based on a kinematic relationship between lateral acceleration measurement and rate of change of lateral velocity. The method provides measurement updates based on virtual lateral velocity measurements from front and rear axle lateral force versus axle side-slip angle tables using the lateral acceleration, yaw-rate, longitudinal speed, and steering angle measurements. The method calculates front and rear axle lateral forces from the lateral acceleration and yaw-rate measurements. The method estimates front and rear axle side-slip angles from the calculated front and rear axle lateral forces using the tables. The method calculates multiple virtual lateral velocities from the front and rear side-slip angles and selects one of the virtual lateral velocities that minimizes an error between a measured force and an estimated force as the lateral velocity.

The method also includes identifying two equations from the calculated lateral forces and the vehicle measurements. The method provides tables that identify a relationship between the calculated front and rear axle lateral forces and the front and rear side-slip angles, and determines the vehicle lateral velocity and surface coefficient of friction from the tables.
