Systems and methods for minimizing motion sickness in vehicles
A motion sickness control system for a vehicle includes a vibrator. The motion sickness control system includes a sensor configured to measure vibration of the vehicle. The motion sickness control system includes a computer having a processor and a memory storing instructions executable by the processor to actuate the vibrator at a target frequency based on the measured vibration of the vehicle. The target frequency attenuates the measured vibration of the vehicle.
Damper control
A vehicle comprising: a vehicle body; a plurality of wheel assemblies each having a rotation axis; at least one suspension linkage, each suspension linkage coupling a respective wheel assembly to the vehicle body to permit motion of the rotation axis of each respective wheel assembly relative to the vehicle body; a damper coupled to a respective suspension linkage to constrain the motion of the associated wheel assembly by applying a damper reaction force to the suspension linkage, the damper being configured to be responsive to a damper force control output to vary the damper reaction force being applied to the suspension linkage; at least one vehicle sensor configured to provide vehicle condition data; and a damper control unit configured to generate the damper force control output that causes the damper to generate respective damper reaction forces to act against the suspension linkage to control the motion of the wheel assembly towards a set position for the wheel assembly relative to the vehicle body, adjust the set position based on a change in the vehicle condition data, and calculate the set position based on variations in the vehicle condition data over time.
Device for decoupling vibrations between two systems and the working machine
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. The 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 (v.sub.z1,1) serving as an input variable of control devices and/or regulating devices. Those devices control a damping system (8) of the one system (2) and/or the other system (4) to compensate for the vibrations. The respective pitch motion of the other system (4) is detected by at least one rotation rate sensor. The respective measured value (ω.sub.1) of the sensor, preferably amplified by only a predeterminable factor (L.sub.1), results in the absolute vertical speed (v.sub.z1,1) as input variable.
