Abstract:
A vehicle integrated control method includes determining a road surface status, determining a vehicle status, determining an integrated control mode by determining a control status of an electronic control suspension and a motion of a sprung mass and an unsprung mass based on the determination results of the road surface status and the vehicle status, and controlling the electronic control suspension and an in-wheel system by determining a control amount based on the determined integrated control mode.
Abstract:
An inclination-measuring apparatus for use with a motor vehicle includes a rotary sensor connected to the motor vehicle, the rotary sensor selected from one of a rotary position sensor and a rotary angle sensor, a pendulum and a controller. The pendulum has a pendulous mass being oriented to hang substantially aligned with the earth's gravitational forces. The movement of the pendulum providing an input to the rotary sensor to generate a signal to ascertain the inclination of the vehicle relative to the earth's gravitational forces. The signal is processed by the controller that is operatively connected to control one of an electric park brake, a chassis leveling device while parked, a lateral inclination device while the vehicle is operational and a longitudinal inclination device while the vehicle is operational.
Abstract:
An automatic leveling vehicle comprising a front frame section and a rear frame section interconnected by a swivel joint which permits pivotable movement of the front frame section relative to the rear frame section about a generally horizontal axis extending longitudinally of the vehicle, a gear train attached to the rear frame section, right and left rear wheel assemblies, right and left rear axle assemblies operatively interconnecting the gear train, a lever arm connected to the gear train for controlling the position of the rear axle assemblies, selective movement of the lever arm causing the right and left rear axle assemblies to move their associated wheel assemblies up or down in opposite directions, a level detector for producing and applying leveling signals for positioning a lever arm control such that the rear frame section is maintained in a relatively level orientation when the rear wheel assemblies encounter an uneven terrain.
Abstract:
An inclinable all wheel drive vehicle with self-leveling chassis and self-locking capabilities, whether it is in motion or at rest, on level or laterally pitched ground. The vehicle has front and rear axle frames independently pivoted about a horizontal central chassis. An automatic tilt sensor controls hydraulics or motor to maintain vehicle's cabin level.

Abstract:
An active suspension system for a vehicle including at least one fluid operated ram having a cylinder and a main piston mounted therein for reciprocating movement, control means for controlling an equilibrium position of the piston in the ram in response to lateral acceleration of the vehicle in order to counter the effects of body roll of the vehicle, and wherein the ram includes shock absorbing means for permitting rapid movement of the piston from the equilibrium position when operating fluid in the ram is subjected to transient increases in pressure.

Abstract:
A zero-point correction device for a gravity-type accelerometer employed in a vehicle having wheels, includes a calculator for calculating an estimated vehicle acceleration Aw based on the wheel speed, and a detector for detecting a gravitationally detected acceleration Am based on said gravity-type accelerometer. A subtractor is provided for subtracting a correction amount Ao obtained in each operation cycle from the gravitationally detected acceleration Am to produce a corrected acceleration Ac which is a corrected version of said gravitationally detected acceleration Am. The correction amount Ao for the present operation cycle is obtained by adding to the correction amount Ao obtained in the previous cycle, a value commensurate with a difference between the estimated vehicle acceleration Aw and the corrected acceleration Ac.
