An embodiment of the invention provides a method and system including a sensor on a vehicle and a processor connected to the sensor. The processor determines a probability of falling based on input from the sensor, whether the probability of falling exceeds a threshold, and a state of an operator of the vehicle. An actuator connected to the processor receives a signal from the processor when the probability of falling exceeds the threshold and when the state of the operator includes an impaired state. Stabilizer wheels are connected to the actuator, where the signal includes a command to deploy the stabilizer wheels.

A lifting arrangement for lifting a wheel axle of a vehicle comprising a first elongated member extending along a first axis comprising a vehicle frame coupling portion for connecting the lifting arrangement to a vehicle frame of the vehicle during use, a second elongated member extending along a second axis comprising a wheel axle coupling portion for connecting the lifting arrangement to the wheel axle of the vehicle during use, wherein the vehicle frame coupling portion and the wheel axle coupling portion are offset from each other by a length and wherein the lifting arrangement is arranged to adjust the length between a maximum length and a minimum length by axially moving the second elongated member along the second axis relative the first elongated member, wherein the lifting arrangement further comprises an engaging device for axially moving the second elongated member along the second axis relative the first elongated member.

A motor vehicle has a steering axle, a drive axle and a lift axle having an actuator for lifting and lowering the same. The wheels of the drive axle can be electrically driven, at least in a supporting manner, via an electric machine operable as an electric motor and as a generator, and the wheels can be driven in a generating manner in a recuperation operation. The electric machine is connected to an accumulator and to a control and/or regulation device to control the operation of the lift axle. The device is connected to sensors for wheel slip detection at the drive axle. The device is configured such that, during a recuperation operation, it can send a command to the actuator to lift the lift axle and thereby unload the wheels thereof, if there is wheel slip at least at one wheel of the drive axle.

A child swing steering vehicle comprises: a vehicle frame; wheels disposed at the bottom of the vehicle frame; steering wheels disposed in rear or front of the wheels; a steering mechanism to steer the steering wheels when the child's body is tilted to the left or right, the steering wheels are connected to the vehicle frame via the steering mechanism; the steering vehicle further comprising auxiliary wheels; the left and right sides of the vehicle frame are respectively provided with at least one auxiliary wheel; a sum of the number of the wheels and the steering wheels is greater than or equal to three, and the bottom of the wheels and the bottom of the steering wheels are both located in the same plane; when the child swing steering vehicle is turning, the bottom of the auxiliary wheel is located in the plane, thereby enabling a good stability in steering.

Systems and methods for reporting on vehicle characteristics determined by the control system of a multi-speed automatic transmission of a vehicle are provided. The control system may output a vehicle mass alert based on a relationship between a vehicle mass threshold and a determined vehicle mass satisfying a condition. The control system may output a vehicle road grade alert based on a relationship between a vehicle road grade threshold and a determined vehicle road grade satisfying a condition.

A work vehicle includes a chassis, an axle assembly, an actuator, a parking brake, and a controller. The axle assembly is coupled to the chassis. The actuator is coupled to the chassis and the axle assembly. The actuator is configured to transition the axle assembly between a raised position and a lowered position. The controller includes a processor and a memory. The controller is configured to generate signals to determine a vehicle state based on data representing at least one of a vehicle load, a vehicle location, and a vehicle operating condition; and operate the actuator to transition the axle assembly between the raised position and the lowered position based on the vehicle state.

A pivotable wheel mount assembly may include a mounting bracket and a swing arm coupled to the mounting bracket. The swing arm may be movably coupled to the mounting bracket or the trailer and to a wheel and/or suspension so as to enable the wheel to be rotated from a downward or operational position to a horizontal or stowed position. The assembly may include an actuator support bracket coupled to the mounting bracket and an actuator that provides mechanical assistance moving the wheels between positions. One or more locking mechanisms may be provided to secure the assembly in either the operational position, the stowed position, or both.

A lift axle suspension for a tandem trailer has first and second suspension air bags for first and second axles. There is a lift air bag that, when pressurized, applies a lifting force to lift the second axle relative to the first axle. A first pneumatic circuit supplies compressed air to the first suspension air bag and a diverter valve and is controlled by a height selector valve that is opened and closed based on the ride height of the trailer. The diverter valve selectively supplies compressed air to the second suspension air bag and a pressure regulator that limits air pressure to a predetermined pressure. A second pneumatic supplies compressed air to the lift air bag and is controlled by a pilot valve.

An autonomous mobile robot is provided. The autonomous mobile robot includes an upper module including a cargo space provided therein, and a cover, a lower module positioned under the upper module and providing a driving force, a driving module provided in the lower module, and a control unit that controls an operation of the driving module, in which the driving module includes a plurality of pairs of wheels capable of asynchronously contacting a road surface or ground so as to overcome a step or a stair.

A method for controlling the safe operation of a rear axle of a set of combined axles powered by a motor vehicle, particularly for a vehicle designed to carry loads and which have 6×4, 8×4 or 10×4 type traction configurations, or tridem models formed by three drive axles. The method includes a set of steps and activities that ensure proper and safe operation of systems and mechanisms for uncoupling and raising a rear axle of a vehicle, and more specifically checking a status of certain operating parameters of the rear axle and of the vehicle itself in order to permit or prevent uncoupling and coupling, as well as raising and lowering of the rear axle of the vehicle.
