Methods and apparatus for adjusting a suspension of a vehicle are described herein. An example apparatus includes a memory storing a plurality of suspension profiles. Each of the suspension profiles includes a stored performance parameter of a vehicle and a suspension setting. The apparatus includes a sensor to detect a driver performance parameter of a driver driving the vehicle. The driver performance parameter represents a behaviour of the driver of the vehicle. The apparatus further includes a processor to compare the driver performance parameter to at least one of the plurality of suspension profiles stored in the memory, and a controller to adjust a suspension of the vehicle according to a first suspension setting of a first suspension profile of the plurality of suspension profiles if the driver performance parameter corresponds to a first stored performance parameter of the first suspension profile.

A suspension monitoring and adjustment system for an off-road vehicle includes a distance sensor arranged to measure shock displacement of a suspension of the vehicle. The system may include an output device configured to output shock displacement data generated by the distance sensor and a processor or programmable circuit operable to produce a visual representation of the shock displacement data output by the output device. The system may include a processor or programmable circuit operable to generate an adjustment signal based on shock displacement data generated by the distance sensor and a suspension adjuster arranged to adjust the suspension of the vehicle in response to the adjustment signal.

A shock absorber is provided that includes a shock body and a shaft assembly. The shock body has an inner chamber. The inner chamber is defined by a cylindrical interior surface. At least one groove is formed in the interior surface within at least one select length of the shock body. A piston of the shaft assembly is received within the inner chamber of the shock body. The piston includes valving to allow dampening matter that is received within the inner chamber to pass through the piston to allow the piston to move within the inner chamber. The at least one groove that is formed within the interior surface is configured to allow at least some of the dampening matter to bypass the valving of the piston to allow the piston to move through the at least one select length with less resistance.

This application relates to a suspension control method and system, a vehicle, and a storage medium. The suspension control method includes: acquiring a pavement image in a traveling direction; identifying a variation type corresponding to a pavement smoothness variation according to the pavement image; generating a control signal according to the identified variation type, to adjust a suspension parameter; detecting, by using a sensor coupled to a suspension, pavement characteristic information corresponding to the variation type; and generating a correction signal based on the pavement characteristic information, to correct the control signal. The suspension control method can identify the pavement smoothness variation more accurately and set the suspension damping parameter according to an identification result.

The invention relates to a method for controlling the driving dynamics of a vehicle by means of dampers, wherein the vehicle comprises at least two axles, which each have at least two wheels including dampers, and wherein the method has the following control:

a) Obtaining a target driving dynamics variable;

b) determining a control deviation using the target driving dynamics variable and an actual driving dynamics variable;

c) Changing the damper force of at least one damper according to the control deviation;

d) Updating and feeding back the actual driving dynamics variable to once again determine the control deviation when the damper force changes.

A vehicle suspension control apparatus includes a mode determination device that determines a mode of a shock absorber for a vehicle, corresponding to an identified speed bump, when the speed bump is identified in front of the vehicle, a suspension control amount calculation device that calculates an amount of suspension control for passing over the speed bump, based on the determined mode of the shock absorber, and a controller that controls a suspension of the vehicle based on the calculated amount of suspension control.

A modular electronic damping control system is described and includes a damping component located at a vehicle suspension location. The modular electronic damping control system also includes a control system configured to control the damping component, and determine the type of damping component present. Also, the control system is configured to automatically tune a vehicle's suspension based on the type of damping component present, and automatically monitor the damping component and determine when a change has been made to the damping component so that the control system can then automatically re-tune the vehicle's suspension based on the change to the damping component.

The present invention obtains a controller capable of improving riding comfort of an occupant at the time when a vehicle that has jumped lands on the ground in comparison with the background art.

The controller according to the present invention is a controller that is mounted to a vehicle including a shock absorber in a damping force adjustment type between a vehicle body and a wheel and controls a damping force of the shock absorber. The controller includes: a jump detecting section detecting that the vehicle has jumped; and a control section that executes landing damping force control for restricting the damping force of the shock absorber during compression to be equal to or smaller than a prescribed damping force when the jump detecting section detects a jump of the vehicle.

An adaptive suspension damper may include a body defining a working chamber, and a sleeve operably coupled to the body to alternately open the working chamber to enable a working fluid to enter or leave the working chamber relative to compression and rebound events experienced at the adaptive suspension damper, and close the working chamber to enable the piston head to act as a hydraulic ram inside the working chamber to selectively adjust a position of a piston head in the working chamber to adjust a height of a corner of a vehicle at which the adaptive suspension damper is located.

A vibration damper includes at least one adjustable damping valve having an outer housing connected to one end of an outer receptacle of the vibration damper. A longitudinal axis of the adjustable damping valve and a longitudinal axis of the vibration damper run parallel. The outer housing of the adjustable damping valve has a clamping surface for an axle connection part.
