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.

An electronically controller external damper reservoir assembly (eRESI) can be connected to a passive damper and/or substituted for an existing external reservoir to provide semi-active damping control. The eRESI includes a reservoir and a variable base valve assembly actuated by an actuator. A controller is in communication with the actuator and a sensor providing input signal indicative of vehicle movement and is programmed to generate a damping control signal to the actuator based on the input signal, to dynamically control the damping force outputted by a passive damper hydraulically connected to the eRESI. A P/T sensor can be installed to a gas chamber of a vehicle damper to generate a P/T signal indicative of the pressure and temperature of the gas. The controller is programmed to determine a damper position of the damper based on the P/T signal.

A vibration damping system configured to improve ride quality as well as controllability and stability of a vehicle. The vibration damping system is applied to a vehicle comprising a vehicle body suspension, and a seat suspension including a spring and a damper. The vibration damping system is configured to: estimate acceleration of a sprung seat mass and a resonance frequency when vibrations propagates to the sprung seat mass; calculate a target value of the acceleration of the sprung seat mass; and set a spring constant of the spring and a damping coefficient of the damper to values possible to achieve the target value of the acceleration of the sprung seat mass, before the vibrations propagate to the sprung seat mass.

A method for operating an adjustable roll stabilizer for a motor vehicle. The adjustable roll stabilizer has an actuator which relative to a rotational axis can be rotated through a system angle in order to twist two stabilizer sections connected to it about the rotational axis relative to one another. The stabilizer sections are each coupled to a respective wheel suspension at a radial distance away from the rotational axis, and, starting from a target angle to be set at the actuator and having regard to the actual system angle and other parameters of the adjustable roll stabilizer and/or the motor vehicle equipped with it, a position-rotational speed regulator determines a target motor torque on the basis of which a motor of the actuator is controlled, so that having regard to the target angle and the actual system angle, the target motor torque is checked for plausibility.

A system for minimizing data transmission latency between a sensor and a suspension controller of a vehicle is described. The system includes: a state determination module that determines a physical state of the vehicle; a plurality of data paths for transmitting a first signal from the sensor to the suspension controller; a data path configurator of the controller that selects a first data path of the plurality of data paths based on at least one characteristic of the first data path and the physical state and configures the first data path to transmit the first signal; and an actuation module that generates an actuation signal to control a damping characteristic of the suspension actuator based on at least the first signal.

Included are an electromagnetic actuator which includes an electric motor configured to generate drive forces for a damping operation and a telescopic operation; an information acquirer which acquires a stroke velocity of the electromagnetic actuator; a drive force arithmetic part which includes a damping force calculator configured to calculate a target damping force and a telescopic force calculator configured to calculate a target telescopic force, and which obtains a target drive force based on the target damping force and the target telescopic force; and a drive controller which controls drive of the electric motor using the target drive force. The drive force arithmetic part includes an adjuster which performs an adjustment to reduce a telescopic control amount for the target telescopic force based on the stroke velocity acquired by the information acquirer.

A method for detecting a defective damper device of a vehicle, including the following steps: monitoring the specific damper travel values (DW) of at least two wheel carriers of the vehicle in a monitoring period (UZ), determining the specific damper speeds (DG) and the specific damper accelerations (DB) on the basis of the monitored specific damper travel values (DW) in the monitoring period (UZ), acquiring the specific damper work values (DA) on the basis of the determined specific damper speeds (DG) and on the basis of the determined specific damper accelerations (DB), generating a comparison result (VE) from a comparison of the acquired specific damper work values (DA) with one another, and generating at least one specific status signal (SS) on the basis of the comparison result (VE) for the at least two wheel carriers.

A control system (300) for controlling an active suspension system (104) of a vehicle (100), the control system comprising one or more controller (301), wherein the control system is configured to: detect (1004) a ramp (202) approached by an overhang of the vehicle; and in dependence on detecting the ramp, control (1020) the active suspension system to modify a relative ride height between a leading ride height at a set of leading wheels (FL, FR) of the vehicle and a trailing ride height at a set of trailing wheels (RL, RR) of the vehicle, to increase a ramp angle (, ) of the vehicle relative to the ramp.
