A method of on-demand energy delivery to an active suspension system is disclosed. The suspension system includes an actuator body, a hydraulic pump, an electric motor, a plurality of sensors, an energy storage facility, and a controller. The method includes disposing an active suspension system in a vehicle between a wheel mount and a vehicle body, detecting a wheel event requiring control of the active suspension; and sourcing energy from the energy storage facility and delivering it to the electric motor in response to the wheel event.

A machine comprises a frame, a plurality of ground engaging units, a plurality of moveable legs, and a hydraulic system. A first ground engaging unit and a second ground engaging unit connect a first leg and a second leg, respectively, with the frame. The hydraulic system controls heights of the plurality of moveable legs. The hydraulic system comprises a fluid circuit to control fluid between the first and second legs, a load holding valve to control fluid flow into the fluid circuit, and first and second relief valves to control flow of fluid between the first and second legs in opposite directions. A method for controlling slope of a construction machine comprises activating a relief valve connecting right and left lifting cylinders to control flow of hydraulic fluid between the lifting cylinders to control retraction of one of the lifting cylinders from retracting.

An omnidirectional moving device is provided with a vehicle chassis, a vehicle body, a universal coupling, and an attitude stabilizing system. In the vehicle chassis, a plurality of wheels that are capable of moving omnidirectionally are provided. The vehicle body is mounted on the vehicle chassis. The universal coupling connects the vehicle chassis to the vehicle body, and the attitude of the vehicle body relative to the vehicle chassis can be changed via this universal coupling. The attitude stabilizing system causes the vehicle chassis to move in a direction that corresponds to a change in the attitude of the vehicle body, and maintains the attitude stability of the vehicle body.

A vehicle includes a front wheel, a front wheel mounting portion, a vehicle body, and a roll mechanism. The wheels are disposed in a pair of the left and right and rotatable about the steering shaft as a rotation center. The portion is disposed in a pair of left and right, and the wheel rotatably mounted and includes a suspension. The body includes a seat on which an occupant sits. The mechanism connects the body and the portion. In the upright state, the roll axis of the mechanism is located at a position higher than the vehicle center of gravity when the occupant is not riding. When the body receives a centrifugal force at the time of turning, only the body among the body and the wheel rolls around the roll axis as the rotation center, whereby the body is inclined inward in the turning direction.

A base unit for a lifting vehicle includes a chassis having a chassis plane and a plurality of wheels, each of the wheels being mounted on the chassis by a suspension mechanism having a suspension element and a suspension actuator that controls the position of the suspension element relative to the chassis. The suspension element is arranged to pivot relative to the chassis about an inclined pivot axis in response to actuation of the suspension actuator.

A connected component platform (CCP) is disclosed. The CCP receives user information and sensor derived data. The system also includes an overall data evaluator to access a performance database and use the user information in conjunction with information from the performance database to evaluate the received user information as a method to develop user guidance data in the area of suspension tuning and suspension maintenance recommendations. The system further includes a data evaluation results formator to receive the user guidance data from the overall data evaluator, format the user guidance data into a user accessible digital format, and output the user guidance data in the user accessible digital format.

A damper control system includes a damper control unit which controls a property of a damper used in a suspension of a vehicle; and a processing unit which accepts feedback data pertaining to behavior of the vehicle measured in the vehicle, applies computational processing specified by executing a machine learning algorithm to the feedback data, and outputs a control variable obtained from the computational processing to the damper control unit. The damper control unit controls the property of the damper on the basis of a control variable used internally within the damper control unit, and replaces the control variable used internally with a new control variable. The new control variable is the control variable output by the processing unit.
