摘要： An air-ride axle/suspension system for a heavy-duty vehicle. A frame and at least a pair of suspension assemblies support opposite ends of an axle for movement relative to the frame. An air spring is associated with one of the suspension assemblies that establishes a first relative position between the axle and the frame as a function of fluid pressure in the air spring. A tire and wheel assembly is operatively mounted to an end portion of the axle associated with the air spring. A sensor detects an inflation condition of the tire and wheel assembly. A venting system exhausts fluid pressure from the air spring to establish a second relative position between the axle and the frame that is different than the first relative position in response to detecting a predetermined inflation condition of the tire and wheel assembly.

摘要： A method of controlling drivability of a vehicle detects an overall load acting on the vehicle. A mass of the vehicle or an estimate thereof is obtained. A controller determines whether the vehicle is negotiating a curve during a driving situation. If the vehicle is negotiating a curve during the driving situation, the controller determines whether the vehicle has a tendency to oversteer or to understeer. The load acting on the vehicle is dynamically changed or a suspension stiffness of the vehicle is dynamically adjusted to reduce the tendency of the vehicle to oversteer or to understeer.

摘要： An axle lift assembly includes a vehicle configured to support a load. A slide assembly has a member that is movable along a longitudinal extent of the vehicle. The slide assembly is operable to secure the member relative to the vehicle at a select position along the longitudinal extent of the vehicle. A swing arm has a first end pivotally coupled with the member and an opposing second end biased away from the vehicle. The swing arm is configured to support a wheel assembly with a tire for contacting a ground surface. An actuator is operably interconnecting the member and the swing arm for raising the wheel assembly toward the vehicle to lift the tire away from the ground surface. The slide assembly and the actuator are operable to respectively adjust longitudinal and vertical positions of the wheel assembly relative to the vehicle for accommodating a condition of the load.

摘要： In a method for operating a vehicle with wheel suspensions which each have a characteristic curve, the characteristic curve generates a relation between the weight of the vehicle, applied to each wheel suspension, and the respective height of the vehicle at the wheel suspension point. At least two height sensors detect the height at the wheel suspensions, a reference height is associated with the height sensors and represents a pre-defined loading state of the vehicle. The method provides: detecting the height, determining the forces applied to the vehicle, determining the acceleration of the vehicle on the basis of the forces applied to the vehicle, determining an estimated value for the mass of the vehicle from the forces and the acceleration of the vehicle, and determining values representing the reference heights from at least the estimated value for the mass of the vehicle, the characteristic curves of the wheel suspensions, and the detected heights.
