Methods, apparatus, systems and articles of manufacture are disclosed to perform a tank turn. An example vehicle includes a first wheel and a second wheel, the first wheel located on an end of a first axle, the second wheel located on an end of a second axle, the end of the first axle opposite to the end of the second axle, a first suspension coupled to the first wheel, a second suspension coupled to the second wheel, and a controller to drive the first axle in a first direction, drive the second axle in a second direction, the first direction different from the second direction, and decrease a first suspension load of the first suspension and a second suspension load of the second suspension.

Methods and systems are provided for adjusting a height of an electric vehicle with an adjustable suspension system. In one example, a method comprises: during a vehicle stop event, adjusting a height of a skateboard frame of an electric vehicle via an adjustable suspension system, based on at least one sensor input indicative of a desired skateboard frame height. In this way, user activities, including loading and unloading, may be facilitated.

The present invention relates to a construction machine, in particular a ground milling machine, with a drive motor, a machine frame supported by a traveling gear with traveling devices, and an operator platform arranged on the machine frame, wherein the traveling gear has a front and a rear traveling gear axle, and wherein at least one of the traveling gear axles is configured as a locking axle with two traveling devices which are height-adjustable relative to the machine frame independently of one another and can be locked in an operating position, and at least one further traveling gear axle is configured as a swing axle such that the traveling devices of the swing axle are jointly height-adjustable relative to the machine frame, and a height adjustment of one traveling device of the swing axle leads to an opposite height adjustment of another traveling device of the swing axle, wherein a control device is provided which is configured such that it detects the load on at least one of the traveling devices of the locking axle as a control variable and, when the load on the traveling device of the locking axle falls below or exceeds a threshold value, blocks the joint height adjustment of the traveling devices of the swing axle relative to the machine frame. Moreover, the present invention relates to increasing the stability of such a construction machine.

A damping control system is provided for an off-road recreational vehicles having a suspension located between a ground engaging member and a vehicle frame and including at least one adjustable shock absorber having an adjustable damping characteristic based on an input from a sensor.

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.

In accordance with one aspect of the present disclosure, a suspension strut for use on a work machine is provided. The suspension strut may have a forged one piece cylindrical inner housing that includes a hollow rod which forms a circumferential piston at an open end and a lower clevis at a closed end of the hollow rod. The suspension strut may further have a forged one piece cylindrical outer housing that includes a hollow barrel having an interior and an exterior surface, a closed end that forms an upper clevis, an open end, and a port on an outside surface of the hollow barrel. Further, the inner and outer housing may be coupled by a disk shaped end cap attached to the open end of the hollow barrel having an inner diameter that is slideably engaged with an outer surface of hollow rod.

A shock absorber adjuster assembly comprising at least one spring arranged so as, in use, to extend between a pair of spaced apart spring seats. At least one of the spring seats is adjustable and is formed by a cylindrical body, a first adjustable member and a second adjustable member. The body has a first thread formed on its outer surface and a second thread formed on its inner surface. The first adjustable member includes a first flange having a threaded inner surface which is engageable with the first thread of the body so that the first flange can be screwed along the first thread. The second adjustable member includes a second flange provided on an end of a shaft. The separation between the first and second flanges can thereby be adjusted by moving of either or both of said first and second flanges.

A hydraulic flow adjuster includes a first hydraulic tank, a second hydraulic tank, and a piston actuator. A first piston operates within the first hydraulic tank and a second piston operates within the second hydraulic tank. The piston actuator adjusts a relative position of the first piston in the first hydraulic tank and a relative position of the second piston position in the second hydraulic tank, such that the relative position of the first piston in the first hydraulic tank is the same as the relative position of the second piston in the second hydraulic tank.

Some embodiments may provide a method for a desired operating environment. A signal to place a vehicle in a designated mode corresponding to a desired operating environment may be received. The designated mode may include modifications to one or more default operating characteristics of the vehicle. The modifications may be while the vehicle is in parked mode and a vehicle access key associated with the vehicle is within proximity of the vehicle. In response to receiving the signal, characteristics of the vehicle to be modified in order to create the desired operating environment may be identified. The default operating characteristics may relate to lighting or displays controlled by the vehicle, sounds controlled by the vehicle, or a passive entry system of the vehicle. One or more settings of the vehicle to change the default operating characteristics of the vehicle while in the designated mode may be modified.

A system for controlling the stability of a vehicle equipped with semi-active dampers includes: an actuator, a plurality of sensors, a low-level control unit, a high-level control unit and a mid-level control unit adapted to execute an algorithm for calculating a damping level (C.sub.ref).
