SUSPENSION DAMPING CONTROL
20250346087 · 2025-11-13 ·

A vehicle includes a suspension system having a damping system that includes a plurality of dampers and a plurality of damper valves. The vehicle further includes one or more processors configured to determine energy content of an acceleration signal indicative of acceleration of the vehicle. The one or more processors are further configured to dynamically tune a cutoff frequency of a high-pass filter based on the energy content of the acceleration signal. The one or more processors are configured to filter, via the high-pass filter, a velocity signal derived from the acceleration signal to output a filtered velocity signal. The one or more processors are configured to control operation of the damping system based on the filtered velocity signal.

Method and apparatus for an adjustable damper

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.

DYNAMIC GROUNDHOOK CONTROL IN A VEHICLE USING AN ACTIVE SUSPENSION SYSTEM

A vehicle may include a vehicle body, a plurality of wheels, an active suspension system operatively coupled to the plurality of wheels and the vehicle body, and at least one processor configured to control the active suspension system. The at least one processor may be configured to determine a first force command based on a vehicle body parameter, determine a second force command based on the vehicle body parameter and a suspension parameter, determine a blend ratio based on the first force command, determine a third force command based at least partly on the blend ratio, the first force command, and the second force command, and command the at least one actuator to apply force between at least one of the plurality of wheels and the vehicle body based at least partly on the third force command.
