  • Publication number: 20240001987
    Abstract: A vehicle vibration control system (VCS) includes a vehicle having at least an engine, a transmission, a frame, a steering column with a steering wheel attached, a passenger cabin, and a controller area network (CAN) bus. The vibration and noise in the cabin and in or around steering column are bothersome to passengers in the passenger cabin. Linear force generators (LFGs) are used to control the noise and vibration in or around the steering column and/or steering wheel. Circular force generators (CFGs) are used to control noise and vibration in the passenger cabin. Sensors are used to measure the noise and vibration.

  • Patent number: 11808318
    Abstract: Systems, devices, and methods for active vibration control using circular force generators. In one aspect, a vehicle includes a vehicle frame, a cabin, an engine, and a number of vibration control devices mounted on the vehicle frame. Each vibration device includes a circular force generator comprising at least one mass and at least one motor configured to rotate the mass. The vibration control devices are configured to perform active vibration control to reduce noise and/or vibration within the cabin resulting from the engine deactivating a subset of cylinders in operation.

  • Patent number: 11660638
    Abstract: Circular force generator devices (100), systems, and methods for damping vibrations which include two complementary rotor assemblies (110, 120) that are rotatable together about a common shaft (102) but that have an adjustable rotational position (P1, P2) with respect to one another such that a significant reduction in rotor inertia and bearing drag relative to conventional CFG configurations is provided. The present architecture creates virtually zero rotating moment.

  • Publication number: 20210356012
    Abstract: A vehicle active vibration control (AVC) system includes a vehicle having at least an engine, a transmission, a controller area network (CAN) bus, a frame, and a cabin. The vibration control devices (120) are distributed about the frame, with each device including a circular force generator (CFG) (122). At least one sensor is positioned on the frame to detect and measure a noise and/or vibration within the cabin. Each sensor creates an electronic data signal and electrically communicates with a corresponding vibration control device. Each vibration control device receives an electronic data signal from a corresponding sensor and vehicle data from the CAN bus. Each vibration control device processes the electronic data signal and the vehicle data. The CFG of each vibration control device generates a vibration canceling force having a magnitude and phase that attenuates noise and/or vibration within the cabin.

  • Patent number: 5864768
    Abstract: A method and apparatus for controlling continuously variable dampers in a vehicle suspension system is provided. A microcontroller receives sensor signals from the vehicle and generates heave, pitch and roll acceleration signals, heave, pitch and roll actual velocity signals, and heave, pitch and roll velocity level signals based on the received sensor signals. Heave, pitch and roll control signals are then calculated based on the acceleration, actual velocity, and velocity level signals, and the continuously variable dampers are adjusted in accordance with the calculated heave, pitch and roll control signals. A deadband schedule function is provided for adjusting the control signals in accordance with the significance of the particular ride event.

  • Patent number: 5788028
    Abstract: A method is shown for determining an operating temperature of a continuously variable hydraulic shock absorber and compensating a control signal therefore. A solenoid 62 provides continuous variability in the damping level a shock absorber produces. The solenoid includes a coil 70 which may be used to determine the temperature of the hydraulic fluid in the shock absorber. An electronic controller 68 uses the temperature to compensate a desired damping signal to account for temperature variations. This allows the shock absorber to provide consistent damping levels for the vehicle throughout a broad temperature range, thereby improving the noise, vibration and harshness characteristics of the vehicle.

  • Patent number: 5461564
    Abstract: An apparatus calibrates a suspension control module of a vehicle to within a preselected tolerance of a predetermined ride height with reference to the vehicle coordinate system, the vehicle having at least one adjustable suspension unit interposed between the sprung and unsprung vehicle mass. The calibration is adjusted for rigid body cross-talk and for suspension system overshoot and undershoot. The apparatus includes a first device for measuring a first distance corresponding to an actual ride height of a vehicle and for generating a first signal representative thereof and a second device for measuring a second distance between the vehicle sprung and unsprung mass and for generating a second signal thereof.
