摘要： Included are an electromagnetic actuator which generates drive forces for a damping operation and a telescopic operation; an information acquirer which acquires information about the drive forces of, and control mode selection information about, the electromagnetic actuator; a drive force arithmetic part which sets a predetermined control mode based on the control mode selection information about the electromagnetic actuator, and sets a target damping force and a target telescopic force of the electromagnetic actuator based on setting information about the control mode; and a drive controller which controls drive of the electromagnetic actuator using a target drive force based on the target damping and telescopic forces set by the drive force arithmetic part. The drive force arithmetic part performs an operation of switching a setting of the predetermined control mode from one to another while a driving force of the electromagnetic actuator is within a predetermined force range.

摘要： Provided is an electromagnetic suspension apparatus capable of achieving both of vibration isolation performance and road holding performance. The electromagnetic suspension apparatus includes an electromagnetic actuator, an information acquisition unit that acquires information on a stroke speed of the electromagnetic actuator and a state quantity of the vehicle, a plurality of filters in which individual gain characteristics are respectively set, a filter setting unit that selectively sets a filter having a gain characteristic suitable for the state quantity of the vehicle from among the plurality of filters, a filter processing unit that performs a filtering process on a stroke speed signal using the filter set by the filter setting unit, and a drive control unit that controls driving of the electromagnetic actuator based on relationship information between the stroke speed after the filtering process and a damping force corresponding to the stroke speed.

摘要： Method for adjusting the damping force of shock absorbers connected between a vehicle body and a wheel at vehicle corners of a motor vehicle, wherein at least one damping force (FLIFT, FPITCH, FROLL) which is referred to a center of gravity of the vehicle body and is divided between axles of the vehicle and between the shock absorbers of the axles is determined as a function of at least one variable which represents a movement of the vehicle body and/or a movement of the respective wheel. For at least one of the damping forces which are referred to the center of gravity of the vehicle body, at least one division factor for the division of the damping forces is calculated between a front axle and a rear axle, and the division of the respective damping force (FLIFT, FPITCH, FROLL) is adapted on the basis of this division factor.

摘要： A damping control system for a vehicle having a suspension located between a plurality of ground engaging members and a vehicle frame includes at least one adjustable shock absorber having an adjustable damping profile and a driver actuatable input. The driver actuatable input may be positioned to be actuatable by the driver in the absence of requiring a removal of either of the hands of the driver from a steering device of the vehicle.

摘要： A method for controlling a suspension system of a vehicle, as well as suspension systems, and a vehicle including a suspension system is provided. The suspension system may include at least one adjustable damping device that is controlled via a control signal, such as from a controller of the suspension system, in order to dynamically adjust the damping characteristic of the damping device. The control signal may be generated on the basis of at least one of current driving dynamics data and optically recorded information about an area of a ground surface.

摘要： An inerter device for a wheel suspension of a vehicle, having an inerter mass and a mechanical inerter drive which is operatively connected to the inerter mass via a coupling device. The coupling device has a control disk connected to the inerter mass and a contour disk connected to the inerter drive. The control disk and contour disk are frictionally in contact with each other via coupling surfaces. The inerter mass is reversibly movable relative to the inerter drive from an operating position into a securing position. The control disk has a contact element which, during the movement of the inerter mass into the securing position, interacts with a mating contact element of the contour disk and therefore reversibly moves the control disk from a coupling position relative to the contour disk into a release position in which the coupling surfaces are separated.

摘要： A system for damping control for a vehicle includes a parameter component and a damping adjustment component. The parameter component is configured to determine one or more driving parameters of a vehicle. The one or more driving parameters include a velocity of the vehicle. The damping adjustment component is configured to adjust damping of suspension of the vehicle during driving based on the one or more driving parameters. The damping adjustment component is also configured to adjust damping of suspension at a zero velocity for a threshold time period in response to transitioning from a non-zero velocity to the zero velocity.

摘要： A non-linear stiffness actuator for a suspension corner employed in a vehicle includes an actuator housing and an actuator shaft configured to transmit an actuator force to the road wheel. The actuator also includes a primary elastic member assembly arranged between the actuator housing and the actuator shaft and configured to exert a primary elastic member force along the actuator shaft. The actuator additionally includes a secondary elastic member assembly configured to exert a variable secondary elastic member force acting between the actuator housing and the actuator shaft. The variable secondary elastic member force is configured to selectively contribute to and subtract from the primary elastic member force to thereby facilitate the non-linear stiffness of the actuator. A vehicle having such a non-linear stiffness actuator is also provided.
