A mobile robot apparatus includes a main body, a first wheel on a first side surface of the main body, a second wheel on a second side surface of the main body, where the first wheel and the second wheel include side surfaces having a convex shape, a first driving device configured to rotate the first wheel and the second wheel, a second driving device configured to move the first wheel and the second wheel to a first position or a second position, and a processor configured to, based on determining that the mobile robot apparatus is inverted to one side, control the second driving device to move a ground-engaging wheel from among the first wheel and the second wheel from the second position to the first position.

A vehicle includes a suspension system having a first damper, a second damper, and a controller. The dampers include housings and pistons sealingly interfaced with an inner diameter of the housing, dividing the damper into a first and second chamber. The suspension system includes proportional variable relief valves which control pressure of fluid entering or exiting one of the first and second chamber of one of the first and second damper. The controller controls the valves to control extension or compression of the first damper and extension or compression of the second damper based on a degree of roll of the vehicle during a turn of the vehicle or a degree of pitch of the vehicle during acceleration or deceleration of the vehicle. The first and second damper control a roll and pitch of the vehicle. The valves control a damping rate of one of the first and second damper.

A vehicle includes a suspension system having a first damper, a second damper, valves and a controller. Each of the first damper and the second damper include a housing and a piston sealingly interfaced with an inner diameter of the housing, dividing the damper into a first and second chamber. Each valve controls flow rate of fluid entering or exiting at least one of the first and second chamber of at least one of the first damper and the second damper. The controller controls the valves to control extension or compression of at least one of the first damper and the second damper based on at least one of a degree of roll of the vehicle during a turn of the vehicle and a degree of pitch of the vehicle during acceleration of the vehicle or a degree of pitch of the vehicle during deceleration of the vehicle.

The present application pertains to a system comprising a multi-axle trailer with a front and a rear. The a multi-axle trailer comprises at least one lift axle configured to be raised or lowered to distribute weight, to increase trailer deflection during a turn, or both. A jeep is mounted between the trailer and a tractor wherein the jeep is configured to decrease weight on one or more axles. A booster is mounted to the rear of the multi-axle trailer. The system is configured such that during raising of the at least one lift axle an increase in air pressure to one or more other axles is increased to offset weight.

A vehicle includes a chassis, an axle, and a sway bar assembly coupled between the chassis and the axle. At least one actuator is configured to move the sway bar assembly relative to the axle to thereby move at least a portion of the chassis toward or away from the axle to adjust an attitude of the vehicle.

An amphibious multi-terrain water planing vehicle including: a. a hull having a top, a bottom, a front end, a rear end, a first side and a second side; b. at least one track frame, in exemplary embodiments a pair of track frames, mounted to the hull; c. a sole propulsion and water planing device including at least one continuous rotatable track having an outside surface and an inside surface, in exemplary embodiments a pair of continuous rotatable tracks, mounted to the at least one track frame, in exemplary embodiments each of the pair of continuous rotatable tracks mounted to each of the pair of track frames; the at least one continuous rotatable track, in exemplary embodiments the pair of continuous rotatable tracks not vertically adjustable relative to the hull wherein the vehicle when transitioning from land to water and vice versa requiring no modification, and wherein the vehicle is able to plane on water from a stand still position.

A suspension system for a wheel assembly of a vehicle includes a telescopic damper configured to mediate between respective sprung and unsprung portions of the wheel assembly, a rebound spring arranged to moderate wheel travel, and a force-transfer system operative to apply a force to change one or more parameters of the suspension system. The application of the force by the force-transfer system is effective in a first operating mode to change a length of the telescopic damper and in a second operating mode to regulate a wheel rate of the wheel assembly. The force-transfer system is controllable to modify a wheel-travel value at which the wheel rate of the wheel assembly changes in the second mode of suspension operation.

Methods and systems are provided for enabling a vehicle for which a jet pump that functions to transfer fuel from a passive side to an active side of a saddle fuel tank is degraded, to reach a desired destination by the taking of mitigating action. The mitigating action includes conducting a driving maneuver in response to an indication that the jet pump is degraded, the driving maneuver conducted in order to transfer a desired amount of fuel from the passive side to the active side. In this way, a vehicle may reach a desired destination even under circumstances where the vehicle may otherwise be unable to reach the desired destination.

A pet mode door and suspension control system and method includes determining whether a door control action has occurred with respect to a door on the vehicle. When determined that the door control action has occurred, the system and method further includes determining whether a pet mode control action is needed. When determined that the pet mode control action is needed, a suspension control command is sent to suspension control system for raising and/or lowering at least one side of the vehicle and a door control command is sent to a power control unit for opening or closing the door in accord with the door control action.

An amphibious multi-terrain water planing vehicle including: a. a hull having a top, a bottom, a front end, a rear end, a first side and a second side; b. at least one track frame, in exemplary embodiments a pair of track frames, mounted to the hull; c. a sole propulsion and water planing device including at least one continuous rotatable track having an outside surface and an inside surface, in exemplary embodiments a pair of continuous rotatable tracks, mounted to the at least one track frame, in exemplary embodiments each of the pair of continuous rotatable tracks mounted to each of the pair of track frames; the at least one continuous rotatable track, in exemplary embodiments the pair of continuous rotatable tracks not vertically adjustable relative to the hull wherein the vehicle when transitioning from land to water and vice versa requiring no modification, and wherein the vehicle is able to plane on water from a stand still position.
