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 (13)

1. A non-transitory computer readable storage medium having stored thereon, computer-executable instructions that, when executed by a computer, cause said computer to perform a method for controlling vehicle motion, said method comprising:

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

comparing said measured vehicle speed value with a stored predetermined vehicle speed threshold value that corresponds to said vehicle, to achieve a vehicle speed value threshold approach status;

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

monitoring a state of a valve within said vehicle suspension damper, wherein said state of said valve controls a damping force within said vehicle suspension damper;

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

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

2. The non-transitory computer readable storage medium of claim 1 , wherein said at least one user-induced input comprises:

a movement of a steering wheel.

3. The non-transitory computer readable storage medium of claim 1 , wherein said at least one user-induced input comprises:

a movement of a brake.

4. The non-transitory computer readable storage medium of claim 1 , wherein said at least one user-induced input comprises:

a movement of a throttle.
