A suspension control system and a method for controlling a damper device of a bicycle include a damper device and a spring device for sprung damping of a relative motion between a first and a second component of the bicycle. The suspension device has a spring unit exhibiting a spring characteristic, and the damper device exhibits a damping characteristic. The spring characteristic of the spring unit is changed under the control of an electrically operated actuator, which in turn is controlled via an electric control device.

A suspension device includes a fluid pressure circuit disposed between a damper, a pump, and a reservoir. The fluid pressure circuit includes an extension-side damping valve disposed in an extension-side passage, a contraction-side damping valve disposed in a contraction-side passage, and a suction passage that connects a discharge path to a supply passage at a point between an electromagnetic throttle switching valve and a supply-side check valve. The suspension device further includes a control unit configured to control the electromagnetic throttle switching valve on a basis of a differential pressure between the extension-side passage and the contraction-side passage.

Provided are an electronic control suspension apparatus and a damping force controlling method thereof, which are capable of changing a damping force of a damper by just manipulating a multistep switch even during driving. The electronic control suspension apparatus for controlling a damping force of a damper installed at each of a front wheel and a rear wheel includes: a multistep switch disposed in a vehicle and configured to change the damping force of the damper in a multistep manner between a hard step and a soft step; and an electronic control unit configured to control the damping force of the damper according to a current amount corresponding to a step selected from the multistep switch, the current amount to be applied to a solenoid valve being preset for each step of the multistep switch.

A method and apparatus are disclosed for cooling damping fluid in a vehicle suspension damper unit. A damping unit includes a piston mounted in a fluid cylinder. A bypass fluid circuit having an integrated cooling assembly disposed therein is fluidly coupled to the fluid cylinder at axial locations that, at least at one point in the piston stroke, are located on opposite sides of the piston. The cooling assembly may include a cylinder having cooling fins thermally coupled to an exterior surface of the cylinder and made of a thermally conductive material. The bypass channel may include a check valve that permits fluid flow in only one direction through the bypass channel. The check valve may be remotely operated, either manually or automatically by an electronic controller. A vehicle suspension system may implement one or more damper units throughout the vehicle, controlled separately or collectively, automatically or manually.

A suspension system for a vehicle is provided. The vehicle is travelling on a substrate. The suspension system includes a plurality of dampers and a controller disposed in communication with the plurality of dampers. The controller is configured to determine that a receiving coil disposed on the vehicle is inductively receiving electrical energy from a transmitting coil. The transmitting coil is disposed remote from the vehicle. The controller is further configured to control a damping level of each of the plurality of dampers to maintain a distance between the receiving coil and one of the transmitting coil and the substrate within a predetermined range or at a constant value.

In a vehicle provided with an in-wheel motor disposed below a spring of a front wheel, an anti-dive angle of a front suspension is set to form an angle which is inclined towards an upper side of the vehicle with respect to a horizontal line drawn from a ground contact point of the front wheel to a rear side of the vehicle, and an arc-shaped trajectory of a wheel center resulting from displacement of the front suspension is set to be movable towards the upper side of the vehicle and towards the rear side of the vehicle.

Example ride control systems and methods are described. In one implementation, a method receives a request to initiate a drive session to help a baby fall asleep in a vehicle. The method identifies a driving route for the drive session and implements the drive session by following the driving route. One or more vehicle-mounted sensors determine whether the baby in the vehicle has fallen asleep during the drive session.

A hydraulic suspension damper includes a tube having an opened end and a closed end defining a compartment. A main piston is disposed in the compartment dividing the compartment into a compression chamber and a rebound chamber. A piston rod is attached to the main piston. A rod guide is disposed at said opened end. A stroke stop arrangement includes an insert and an additional piston attached to the piston rod. The insert has a narrowed section including an inner surface defining at least one recess between the distal end and the rod guide and extends axially along the insert in fluid communication with the compression chamber for allowing working liquid flow from the rebound chamber to the compression chamber during the rebound stroke. The at least one recess includes three recesses disposed equidistantly and spaced from one another.

A vehicle shock absorber system configured with more than one pressure cylinder that provides advantageous damping characteristics for different loads. There is provided a vehicle shock absorber system having a primary pressure cylinder including upper and lower primary chambers separated by a primary piston head, an auxiliary pressure cylinder including upper and lower auxiliary chambers separated by an auxiliary piston head, a first connection conduit connecting the upper primary chamber and the upper auxiliary chamber, a second connection conduit connecting the lower primary chamber and the lower auxiliary chamber, and a cylinder valve arrangement configured to regulate fluid flow to the auxiliary pressure cylinder.
