System and method for vehicle chassis control

ActiveUS20140312580A1Reduces or even eliminates tyre scrubReduce impactCyclesSteering deviceHydraulic cylinderHydraulic fluid
There is provided a vehicle comprising a chassis, two surface-engaging front wheels, at least one surface-engaging rear wheel and a propulsion unit for driving either the front wheels or the rear wheel or wheels. Each front wheel being connected to the chassis by means of a front wheel support assembly, wherein the front wheel support assembly comprises a hydraulic cylinder associated with each front wheel. Each hydraulic cylinder comprises a housing connected to one of the chassis and the front wheel support assembly, and a piston connected to the other of the front wheel support assembly and the chassis. The piston is moveable within the housing and arranged to divide the hydraulic cylinder into first and second chambers each having respective ports arranged to allow hydraulic fluid to enter and exit the respective chamber, the ports of the first chambers of each hydraulic cylinder being in fluid communication and the ports of the second chambers of each hydraulic cylinder being in fluid communication such that movement of hydraulic fluid from the first or second chamber of one hydraulic cylinder to the respective first or second chamber of the other hydraulic cylinder displaces the pistons of the hydraulic cylinders in opposing directions relative to the respective housings to enable the vehicle to tilt.

Relieving Urban Traffic Congestion

A method of reducing congestion on a roadway is disclosed comprising dividing selected lengths of selected normal lanes of a roadway into two commuter lanes, providing distinctive lane markings to identify the commuter lanes, and dynamically designating selected lengths of selected lanes as either normal lanes or pairs of commuter lanes. In order to dynamically change lane configurations, a set of indicators can be provided as lane markers together with a control system to alter particular lane configurations between normal lanes and commuting lanes both cyclically according to a preprogrammed schedule and dynamically in response to sensed vehicle traffic volume, unusual events such as accidents, weather, and so on. Commuter lanes are designated cyclically and dynamically in response to traffic conditions to increase the capacity of the affected road. Normal lanes are designated at other times. To facilitate entry and exit from designated commuter lanes, transition zones can be provided where entering and exiting commuter lane traffic has right of way.
A commuter vehicle is disclosed for use on commuter lanes. A typical commuter vehicle weighs less than 650 lbs., has at least three wheels, an enclosed seating compartment, and a low center of gravity with at least one occupant. In one embodiment, occupants sit in a near-kneeling position to lower their center of gravity. In, an alternate embodiment also providing a low center of gravity, occupants sit in a recumbent position. A mechanism can be provided to raise and lower the seats to facilitate occupant entry and exit. Occupants can be position in-line, one behind the other. Embodiments with two, three, or more seats can be provided.
