The action of the first hydraulic cylinder is controlled such that a swing position of the first link is located at a target position, based on the result of detection performed by a position detection sensor, and the action of the second hydraulic cylinder is controlled such that thrust has a target value, based on the results of detection performed by pressure sensors.

A weight sensing assembly for a semi-trailer truck enabling balancing of a load includes a sensing module, which is one of a plurality thereof. The sensing modules are mountable to wheels of the semi-trailer truck so that each axle has a sensing module engaged to outside wheels thereof. The sensing module obtains a pressure measurement of a tire engaged to the wheel and transmits it to an electronic device. Programming code on the electronic device enables it to utilize a pressure change, upon positioning of a load upon the semi-trailer truck, to determine a weight that is positioned upon an associated axle. The electronic device calculates adjustments to positions of a sliding fifth wheel and of sliding tandems of the semi-trailer truck to obtain positions thereof that will achieve a legal weight distribution of the load. The electronic device presents, upon a screen thereof, the adjustments to a user.

The second actuator is coupled to the first end of the chassis and positioned on an opposing second side of the longitudinal center axis. The second actuator is extendable to selectively engage a second contact point on the axle.

A driving module of an autonomous mobile robot is provided. The driving module includes a first wheel in constant contact with ground or road surface and having a first rotational axis; second and third wheels constrained in their positions relative to each other; a rear bar on which a second rotational axis of the second wheel is positioned at one end, an upper axis portion is provided at the other end, and an intermediate axis portion is provided in the middle; a front bar on which a third rotational axis of the third wheel is positioned at one end, in which the other end of the front bar is pivotably coupled to the intermediate axis portion; and a suspension unit of which one end is pivotably coupled to the upper axis portion and the other end is pivotably coupled to the third rotational axis or the front bar.

Provided is a control device for a steer-by-wire steering mechanism, the control device including: a tire lateral force detection unit configured to detect tire lateral forces acting on left and right wheels; and a toe angle control unit configured to control toe angles of left and right wheels independently of each other such that the detected tire lateral forces become target lateral forces. Not during deceleration, the toe angle control unit sets target lateral forces FLt and FRt such that the total sum of the left and right target lateral forces is not changed and the total sum of absolute values thereof is decreased, and during deceleration, the toe angle control unit sets the target lateral forces FLt and FRt such that straight traveling stability can be obtained.

The present disclosure discusses a method of operating a vehicle having a set of tires and an active suspension system. The method includes operating the vehicle to travel along a road surface, sensing, using a smart tire assembly, a magnitude of one or more physical quantities associated with at least one tire of the set of tires, and controlling the active suspension system of the vehicle based at least in part on the magnitude of the sensed one or more physical quantities.

The present invention relates to a control unit for determining a value indicative of a load bearing capability of a ground segment supporting a vehicle. The control unit is configured to issue a control signal to the vehicle to thereby impart a motion change of the vehicle, and receive response information from the vehicle indicative of the vehicle's response to the imparted motion change. The control unit is further configured to, based on the response information, determine a vertical position change of at least one wheel of the vehicle, and based on the determined vertical position change and the imparted motion change, determine the value indicative of the load bearing capability of the ground segment.
