A suspension device includes: a damping device that damps a force generated between a vehicle body and a wheel of a vehicle; a determination unit that determines whether the vehicle is jumping, using an acceleration of the vehicle in a front-rear direction, an acceleration of the vehicle in a left-right direction, and an acceleration of the vehicle in a vertical direction; and a damping force control unit that increases a damping force of the damping device so as to be greater than the damping force generated when the determination unit does not determine that the vehicle is jumping, when the determination unit determines that the vehicle is jumping.

A mechanical bypass for a shock assembly is disclosed herein. The assembly has a damper chamber having a compression portion and a rebound portion. There is further an external reservoir in fluid communication with the rebound portion of the damper chamber via a flow path. A valve is coupled with the flow path, the valve to meter a flow of the working fluid through the flow path. A bypass port to the external reservoir is provided in the flow path and bypasses the valve. A mechanical relief valve is provided in the bypass port to block a fluid flow though the bypass port until a blow-off pressure that is higher than a normal operating pressure and less than a burst pressure of the damping chamber is provided thereon.

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.

An acceleration of a head of an occupant of a vehicle relative to the vehicle is determined based on data describing motion of the vehicle and respective poses of the head from a plurality of consecutive frames of image data. A vehicle suspension is adjusted based on the determined acceleration.

A vehicle includes a suspension system having a first damper, a second damper, and a controller. The dampers include housings and pistons sealingly interfaced with an inner diameter of the housing, dividing the damper into a first and second chamber. The suspension system includes proportional variable relief valves which control pressure of fluid entering or exiting one of the first and second chamber of one of the first and second damper. The controller controls the valves to control extension or compression of the first damper and extension or compression of the second damper based on a degree of roll of the vehicle during a turn of the vehicle or a degree of pitch of the vehicle during acceleration or deceleration of the vehicle. The first and second damper control a roll and pitch of the vehicle. The valves control a damping rate of one of the first and second damper.

A vehicle control device includes: a control portion that makes, of a plurality of shock absorbers included in a vehicle, a first damping force of at least one shock absorber that is located on a first direction side on which acceleration acts in a longitudinal direction of the vehicle larger than a second damping force of at least one shock absorber of the plurality of shock absorbers that is located on a second direction side opposite to the first direction in the longitudinal direction of the vehicle before acceleration acting on the vehicle is detected by an acceleration sensor due to acceleration or deceleration of the vehicle.

In some embodiments, methods and systems may be used to control operation of various systems of the vehicle based on road features included in an upcoming portion of a road surface located along a path of travel of the vehicle. This control may either be based on a probability of encountering a road feature on the road surface 5 and/or frequency information related to the upcoming portion of the road surface.

A suspension system for a vehicle includes a shock absorber unit operably coupled between a vehicle body and a wheel carrier. The shock absorber unit includes a first damper unit having a first cylinder chamber, a second damper unit having a second cylinder chamber, a first piston connected to a first piston rod, a second piston connected to a second piston rod, and an adjusting unit. The first and second cylinder chambers may each be filled with a fluid. The first and second cylinder chambers may be formed in a common cylinder unit and sealed off from one another. The first and second piston rods may be arranged axially displaceable in the first and second cylinder chambers, respectively. The first piston rod is operably coupled to the vehicle body and the second piston rod is operably coupled to the wheel carrier. Damping actions of the first and second damper units are changed independently of one another by the adjusting unit.

A control device for a vehicle is provided. The vehicle comprises vehicle axles, a chassis, and at least two sensor modules. The control device comprises an energy supply unit. The control device is configured to supply energy to the at least two sensor modules via the energy supply unit. The at least two sensor modules are permanently connected to one of the vehicle axles of the vehicle. A vehicle is also provided. The vehicle comprises vehicle axles, a chassis, a sensor arrangement, and a control device comprising an energy supply unit. The sensor arrangement comprises at least two sensor modules which are permanently connected to the vehicle axle and each comprise a supply connection for providing energy into the respective sensor module.

The present disclosure relates to a method and an apparatus for controlling an electronic control suspension using a deep learning-based road surface classification model. The method for controlling an electronic control suspension in a vehicle including a camera and a GPS receiver may include collecting location information of the vehicle using the GPS receiver while driving, identifying whether there is a previously generated road surface classification model corresponding to a front obstacle when the front obstacle is detected, determining a first control value based on a first characteristic value corresponding to the road surface classification model when there is the road surface classification model as a result of the identification, controlling the electronic control suspension with the determined first control value when entering the obstacle, and collecting new sensing data through a physical sensor, and correcting the first characteristic value based on the new sensing data.
