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.

Claims (7)

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 set of control signals, wherein at least a first control signal of said set of control signals comprises a set of values associated with at least one user-induced input, wherein at least one vehicle suspension damper is coupled to a frame of said vehicle;

accessing a set of release thresholds associated with a throttle position and a throttle velocity of said at least one user-induced input;

comparing said set of values associated with said at least one user-induced input with a predetermined user-induced input threshold value, to achieve a user-induced input threshold value approach status;

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 user-induced input threshold value approach status and said set of release thresholds, determining a control mode for said at least one vehicle suspension damper; and

according to said control mode and based on said monitoring, regulating damping forces within said at least one vehicle suspension damper by actuating said at least one valve to adjust to a desired state, such that a tilt of said frame is reduced.
