Abstract: A height adjustment system for a vehicle includes: a reservoir configured to hold hydraulic fluid; at least one lift actuator operably disposed between a wheel and a chassis element of the vehicle for adjusting the height of the vehicle; a supply pump having an inlet port in fluid communication with the reservoir and configured to transfer the hydraulic fluid to the at least one lift actuator via a manifold; a supply check valve configured to allow fluid flow from an outlet of the supply pump to the manifold while blocking fluid flow in an opposite direction; and at least one of: a supply pump isolation valve configured to selectively bypass hydraulic fluid around the supply check valve, or a secondary actuator isolation valve configured to selectively control fluid flow between the at least one lift actuator and the inlet port of the supply pump.

Abstract: A system and method of vehicle stability enhancement control the method comprising the steps of determining a Delta Velocity of the vehicle, determining one of an understeer and an oversteer condition of the vehicle, applying a percentage of the Delta Velocity to an outside front and an outside rear wheel in the oversteer condition, and applying a percentage of the Delta Velocity to an inside front and an inside rear wheel in the understeer condition. The system and method may further comprise the step of applying the Delta Velocity to a rear wheel during the oversteer condition or applying the Delta Velocity to a front wheel during the understeer condition using fluid pressure from a master cylinder when braking is occurring.
