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.

Abstract: A method for controlling vehicle motion is described. The method includes: accessing a set of control signals, wherein at least a first control signal of the set of control signals includes a set of values associated a pressure applied to a vehicle component of a vehicle; accessing a set of predetermined vehicle component base-level pressure values associated with the vehicle component; comparing the set of values associated with a pressure applied to the vehicle component with the set of predetermined vehicle component base-level pressure values; based on said comparing, calculating an approximate shift in a center of gravity of the vehicle; monitoring a state of at least one valve; and based on the calculating and the monitoring, determining a control mode for said at least one vehicle suspension damper that, if actuated, would compensate the vehicle for the shift in the center of gravity.
