摘要： A semi-active control methodology is provided for a spring/mass system, for example a real-time adjustable shock absorber system. The methodology includes defining a plurality of operating zones based on system parameters and user-definable or preset inputs. The methodology also includes processing to account for non-inertial spring/mass system response and multidimensional forces acting on the system, and an acceleration hedge calculation to accurately define system operation at extrema of travel. The methodology is generally directed at producing a plurality of valve control signals, selecting among the valve control signals, and applying the selected control signal to the valve in a closed-loop feedback system to adjust the energy in the spring/mass system.

摘要： A roll control system (16) for an automotive vehicle (10) is used to actively detect if one of the plurality of the driven wheels (12) is lifted. The system generates a pressure request to determine if the wheel has lifted. By comparing the change in wheel speed of a driven wheel to a change in wheel speed threshold the wheel lift status can be determined. The wheel speed change threshold may be dependent upon various vehicle operating conditions such as powertrain torque, braking torque and/or longitudinal force on the vehicle.

摘要： A control system that senses misalignment of components in a vehicle drive train system and adjusts the vehicle ride height to realign the components. A control unit monitors vibration, torque or other operating parameters of a vehicle's drive train or other vehicle components and determines whether the parameters are abnormal. If the monitored parameters are abnormal, then the control unit controls suspension elements on the vehicle to adjust the ride height of the vehicle and subsequently the alignment of the drive train, for example, the operating angle of the driveshaft. A ride height sensor feeds back ride height measurements as the suspension elements are adjusted to assist in finding an optimal ride height that eliminates or reduces excess vibration and/or torque. In another embodiment, the control unit adjusts the ride height based on vehicle speed or fuel economy to reduce the profile of the vehicle and improve fuel economy.

摘要： A motor vehicle has a body supported on a front pair of wheels and a rear pair of wheels with front suspension apparatus providing controllable vertical wheel constraint and roll stiffness and a rear pair of wheels with rear suspension apparatus providing controllable vertical wheel constraint and rear roll stiffness. Responsive to a commanded vehicle acceleration or braking, the driven wheel (acceleration) or front (braking) suspension apparatus is briefly altered to provide optimal tire patch traction for the one of the pair of wheels. The alteration may be further responsive to vehicle speed and/or lateral acceleration. The controllable part of the suspension apparatus may be dampers, springs or anti-sway apparatus such as torsion bars. If anti-sway apparatus, the front and/or rear roll stiffness may be controlled to promote oversteer at low vehicle speed and understeer at high vehicle speed.

摘要： A control system for an automotive vehicle having a vehicle body includes a sensor cluster having a housing oriented within the vehicle body. A roll rate sensor is positioned within the housing and generates a roll rate sensor signal corresponding to a roll angular motion of the sensor housing. A controller receives the roll rate sensor signal, the controller generates a residue signal in response to a sensor error or a measurement error. The controller sets a fault condition in response to the residue signal larger than a dynamic threshold and a magnitude of the roll rate signal above a fault condition threshold. The controller sets a fault flag in response to the fault condition indicated for a predetermined time during which no double wheel lift occurs.

摘要： One or several vibration dampers of a vehicle suspension have a damping force arrangement wherein a control signal is computed within the actuating range in accordance with a standard control method for adjusting the damper characteristic. The drive of a damper adjustable in accordance with this invention is so improved that body movements (notwithstanding a harder adjusted damping for critical driving situations) are substantially suppressed as early as possible. In specific driving situations, the adjusting range of the damper force is changed in that the upper limit of the adjusting range is raised or lowered and/or the lower limit of the adjusting range is raised or lowered. A soft damper setting takes place preferably in dependence upon signals which announce or display a change of the vehicle longitudinal deceleration or vehicle transverse acceleration.

摘要： An apparatus and method for determining when a component of a work vehicle experiences vibration above a predetermined threshold, and responding to the vibration so that the vibration is reduced below the predetermined threshold. The apparatus, which is in a work vehicle that includes a chassis, an operator's cab and an active cab suspension system, includes a sensor that is configured to sense a quantity representative of the vibration experienced by the component of the work vehicle and to develop a first signal indicative of that quantity. The apparatus also includes a signal processor that is coupled to the sensor and is configured to develop, in response to the first signal, a second signal indicative of whether the vibration experienced by the component is above the predetermined threshold. The apparatus further includes a device that is coupled to the signal processor and, in response to the second signal, is either configured to provide an indication or configured to take an action to reduce the vibration below the predetermined threshold when the vibration is above the predetermined threshold.
