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： An electrically powered suspension system includes: an electromagnetic actuator provided between a vehicle body and a wheel of a vehicle and configured to generate a damping force for damping vibration of the vehicle body; a wheel speed sensor that detects a wheel speed of the wheel; a wheel speed variation amount calculation part that calculates a wheel speed variation amount on the basis of wheel speed detection values detected by the wheel speed sensor; a 3D gyro sensor that detects sprung state amounts including a sprung pitching action of the vehicle; and a wheel speed variation amount correction part that estimates a variation component in the wheel speed variation amount on the basis of a sprung pitch amount and corrects the wheel speed variation amount so as to reduce the estimated variation component.

摘要： A control unit that controls control currents supplied to shock absorbers that generate damping forces according to the control currents determines coefficients of two functions that functionally identify an equivalent damping coefficient and an equivalent spring constant of each suspension based on relationships between the control current supplied to each shock absorber and the coefficients of the two functions that change according to the control current and a frequency of a relative vibration between a sprung and an unsprung of a vehicle, and calculates a relative displacement or a relative velocity between the sprung and the unsprung based on a vertical acceleration detected by a detection device and the two functions in which the coefficients are determined.

摘要： A damper control system for a vehicle may include a damper-relative-velocity estimation module measuring a vertical acceleration of a vehicle body through a sensor mounted on the vehicle and estimating a damper velocity of a suspension based on the measured vertical acceleration, and a control module reducing movement of the vehicle body by actuating a damper using the damper velocity of the suspension estimated through the damper-relative-velocity estimation module.

摘要： A method for determining vehicle characteristic variables of a motor vehicle. The motor vehicle has active dampers which can set adjusting forces at the respective wheel suspensions in order to be able to raise and/or lower the body of the motor vehicle and which can also measure the acting forces. Specific predefined adjusting forces of the active dampers are imparted in order to ascertain vehicle characteristic variables from the resulting adjustment and the resulting measured forces.

摘要： A forecarriage (8) of a rolling motor vehicle (4), comprising a forecarriage frame (16), a pair of front wheels kinematically connected to each other and to the forecarriage frame (16) by means of a first kinematic mechanism (20), each wheel being connected to said first kinematic mechanism (20) by means of a respective axle journal (60), a roll block system (100) comprising a second kinematic mechanism (110) that directly connects the two wheels to one another at the respective axle journals (60) between two connection points and can assume a free configuration in which the second kinematic mechanism (110) can passively follow the movements of the two wheels with respect to each other without interfering with them and a blocked configuration in which the second kinematic mechanism (110) can set the distance between said two points thus preventing rolling movements between the two wheels while allowing pitching and steering movements.

摘要： 1. A device for decoupling vibrations between two systems and a working machine2. A device together with an assigned working machine for decoupling vibrations between two systems (2, 4) in the form of spring-mass oscillators, of which one system (2) is assigned to a motion machine and the other system (4) is assigned to an operator operating the motion machine, which other system (4) at least partially performs motions about a transverse axis (Q) during driving motions of the motion machine and in doing so is subject to vertical motions in the direction of a vertical axis (z) at an absolute vertical speed (νz1,1), which serves as an input variable of control devices and/or regulating devices, which control a damping system (8) of the one (2) and/or the other (4) system to compensate for the vibrations, is characterized in that the respective pitch motion of the other system (4) is detected by at least one rotation rate sensor, the respective measured value (ω1) of which, preferably amplified by only a predeterminable factor (L1), results in the absolute vertical speed (νz1,1) as input variable.
