Abstract

A method for controlling vehicle motion is described. The method includes accessing a set of control signals including a measured vehicle speed value associated with a movement of a vehicle. A control signal associated with user-induced input is also accessed. The method compares the measured vehicle speed value with a predetermined vehicle speed threshold value to achieve a speed value threshold approach status, and then compares the set of values to achieve a user-induced input threshold value approach status. The method monitors a state of a valve within the vehicle suspension damper, and determines a control mode for the vehicle suspension damper. The method also regulates damping forces within the vehicle suspension damper.

First claim

What we claim is:

1. A non-transitory computer readable storage medium having stored thereon, computer-executable instructions that, when executed by a computer, cause the computer to perform a method for controlling vehicle motion of a vehicle, said method comprising:
accessing a first control signal comprising a value associated with a pressure applied to a vehicle component of said vehicle, wherein at least one vehicle suspension damper is coupled to a frame of said vehicle;
accessing a predetermined vehicle component base-level pressure value associated with said vehicle component;
comparing said value associated with said pressure applied to said vehicle component with said predetermined vehicle component base-level pressure value;
based on said comparing, calculating an approximate shift in a center of gravity of said vehicle;
monitoring a state of at least one valve within said at least one vehicle suspension damper, wherein said state controls a damping force within said at least one vehicle suspension damper;
based on said calculating and said monitoring, determining a control mode for said at least one vehicle suspension damper that, when actuated, would compensate said vehicle for said approximate shift in said center of gravity; and
according to said control mode, regulating said damping force within said at least one vehicle suspension damper by actuating said at least one valve such that said center of gravity is approximately restored, and wherein said pressure applied to said vehicle component is selected from the group consisting of: a pressure applied to a seat of said vehicle and a pressure applied to a cargo bay of said vehicle.
