The elevating lift with a stabilized movable base includes a base with extendable legs that provide minimum to maximum adjustable stability during use and transport. A lift system is mounted on the base, and a platform assembly is mounted on top of the lift system for selective raising or lowering. Each extendable leg supports a caster, rendering the base movable, and selective extension and retraction of the legs adjusts the stability of the lift. The plurality of legs can be further driven to simultaneously rotate about the vertical axis to steer the lift. The stabilized movable base is further alternatively used in combination with a stool, providing minimum to maximum stability during use and transport of seating, and multiple elevating lifts may be used to support linked platform assemblies in various configurations.

An automatic tilting vehicle comprises left and right front wheels and a rear wheel. A control unit controls a vehicle tilting device so that the tilt angle of the vehicle becomes the target tilt angle. The control device is configured to swingingly vibrates the vehicle in the lateral direction by tilting the vehicle by the vehicle tilting device, to estimate a height of the center of gravity of the vehicle based on a resonance period of swinging vibration of the vehicle, and to correct the target tilt angle such that a perpendicular passing through the estimated center of gravity passes within a range of a triangle formed by connecting grounding points of the left and right front wheels and a grounding point of the rear wheel.

A method for controlling vehicle motion is described. The method includes accessing a set of control signals including a measured vehicle speed value associated with a movement of a vehicle. A control signal associated with user-induced input is also accessed. The method compares the measured vehicle speed value with a predetermined vehicle speed threshold value to achieve a speed value threshold approach status, and then compares the set of values to achieve a user-induced input threshold value approach status. The method monitors a state of a valve within the vehicle suspension damper, and determines a control mode for the vehicle suspension damper. The method also regulates damping forces within the vehicle suspension damper.

Aspects of the present disclosure relate to a locking control method for a pivot axle of a wheeled working machine including: determining, using a multibody simulation model, a current posture and motion state of the working machine and static and dynamic forces acting on the working machine; determining a relevant tipping line based on a current locking status of a pivot axle of the working machine; calculating torques acting on the working machine based on the information on current posture, motion state, static and dynamic forces; determining a control command for a pivot axle locking mechanism of the working machine based on the calculated torques and the tipping line; and providing the control command to a pivot axle locking mechanism.

Methods, apparatus, systems, and articles of manufacture to determine the load of a vehicle via calibrate a suspension sensor are disclosed herein. An example vehicle described herein includes a force transducer, an actuator coupled to the force transducer, memory including instructions and a processor to execute the instructions to engage the actuator to a bottom surface of a vehicle, apply a first force to the bottom surface via the actuator, determine a first displacement of a first suspension component of the vehicle, and calibrate a first sensor of the vehicle based on the first force and the first displacement.

The present disclosure relates to a method of determining whether a frame of a work machine is approaching a tip over point. First and second loads upon respective first and second support arrangements of the frame are detected using respective first and second sensing means. Signals are generated indicative of the first and second loads and communicated to a controller. The controller is configured to generate an alert based upon the first and second loads when the first and/or second load signals indicate that the orientation of the work machine is approaching a tip over point.

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.

An axle load monitoring system is disclosed for a load-transporting motor vehicle having two or more primary axles and one or more auxiliary axles wherein the monitoring system detects a noncompliant axle carrying weight condition when the weight of the vehicle acting on any primary axle exceeds a prescribed maximum allowable axle carrying weight assigned to that axle and also when the weight acting on any group of the axles arranged consecutively exceeds a prescribed maximum allowable axle group carrying weight assigned to that axle group. And on such detection, the monitoring system recommends auxiliary axle usage that would result in no maximum allowable axle carrying weight and maximum allowable axle group carrying weight being exceeded provided the current gross vehicle weight does not exceed a prescribed maximum allowable gross vehicle weight determined by all of the axles and the current center of gravity of the vehicle is located within a certain compliance-manageable range. And with the monitoring system also recommending optimal auxiliary axle usage in other situations where full compliance may not be possible for various reasons.
