摘要： A control mode for a damping force characteristic is set to be a variable control when a product of the sum xb′ of sprung member speeds and a sprung-member-unsprung-member-relative-speed xs′ is positive. Accordingly, when the vibration in a middle/high frequency range is not being input to a suspension apparatus, an operation of a variable throttle mechanism is controlled so that a step number representing the damping force characteristic of a damper varies with a vibration state of a sprung member HA based on a Nonlinear H∞ control theory. When the product of xb′ and xs′ is negative, the control mode is set to be an operation prohibiting control. When the vibration in the middle/high frequency range is input to the suspension apparatus, operation of the variable throttle mechanism is prohibited, and suppresses an increase in the operation frequency or in the operation amount of the variable throttle mechanism.

摘要： A self-propelled vehicle includes a main frame which has a main-frame longitudinal axis. First and second powered wheel/suspension assemblies are connected to the main frame near respective first and second ends of the main frame. A steering system includes a hand-held steering controller, in an operator's cab, which turns the first and second wheel/suspension assemblies simultaneously and in opposite directions. A dump box and hydraulic dump box hoist mechanism are supported by the main frame. The operator's cab is supported along a transverse cab axis, perpendicular to the main-frame longitudinal axis, at a fixed longitudinal position along the main frame. A television-based pathway monitoring system includes a camera cluster and multiple viewing screens in the operator's cab. The multiple viewing screens are positioned in the operator's cab such that an operator need not change one's directional orientation when the vehicle moves in opposite directions.

摘要： A control system for a plurality of motor vehicle chassis subsystems comprises a reference model, a state estimator, a feedforward controller, and a feedback controller. The reference model computes desired states of the chassis subsystems. The state estimator estimates actual states of the vehicle. The feedforward controller computes a control value based on input from the reference model, and the feedback controller computes a control value by comparing the estimates of actual states with the desired states.

摘要： The present invention provides a control system operable to raise and lower the height of a vehicle based in part on the response characteristics of the vehicle's suspension and vehicle loading. The control system may develop a vehicle suspension system response by mapping a correlation between changes in air pressure of air springs in the vehicle's suspension and a test valve-open-time. During operation, the control system may predict a valve-open-time in response to a command relating to a target air pressure for the air springs, and then inflate or deflate one or more of the air springs for a duration substantially equal to the predicted valve-open-time. This process may be iterated until the control system achieves, within an acceptable degree of error, the target air pressure for the one or more air springs.

摘要： A system and method for facilitating ride and stability control of a vehicle. The system includes a plurality of suspension displacement sensors, with each of the plurality of suspension displacement sensors positioned proximate to a suspension element of the vehicle. The system further includes a nonlinear filter for filtering out a wheel hop frequency from the suspension velocity corresponding to at least one of the plurality of suspension displacement sensors to obtain a resultant suspension velocity. The resultant suspension velocity is used by a control unit to determine the pitch velocity, roll velocity and the heave velocity of the vehicle.
