Electronic height control

摘要

A method for controlling the ride height in a suspension of an over the highway truck or tractor based on rear axle load. A load on the rear axle is measured. An optimum ride height is calculated at core response to correct drive lighted angles based on the rear axle load. The actual ride height is measured. The difference between the optimum ride height and the actual ride height is calculated. A component of the suspension, such as an air spring, is adjusted to adjust the actual ride height to a height closer to the optimum ride height.
