A hydraulic-magnetic engine includes a two-stage piston having a middle section and a piston plunger, and a chamber with two separate chambers, a piston chamber and a piston plunger chamber containing fluid throughout. The cross-sectional area of the middle section is greater than the cross-sectional area of the piston plunger. The piston is magnetically propelled up and down and in the process fluid is transferred and exchanged between the two chambers and a hydraulic compensator. The reciprocal motion of the piston is activated and sustained by alternating magnetic attraction and repulsion between the piston and the chamber, while the engine power output is amplified by the hydraulic activity.

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.

An apparatus includes an electric motor including a stator and a translator; a three-phase inverter electrically coupled to the electric motor; a power source electrically coupled to the three-phase inverter; and a controller communicatively coupled to the three-phase inverter. The controller is programmed to determine at least three measurements at different times of flux linkage from the electric motor, represent the measurements in Clarke coordinates, determine Clarke coordinates of a center of a circle defined by the Clarke coordinates of the measurements, and determine a position of the translator relative to the stator based on the Clarke coordinates of the center of the circle.

The present invention provides a suspension system capable of adjusting a vehicle height in a short time. The suspension system includes a front wheel-side suspension and a rear wheel-side suspension each provided between a vehicle body and an axle and configured to adjust a vehicle height according to supply and discharge of hydraulic fluid, a pressurization device configured to pressurize the hydraulic fluid, and a first tank and a second tank configured to store therein the hydraulic fluid pressurized by the pressurization device. When the suspension system lowers the vehicle height by each of the front wheel-side suspension and the rear wheel-side suspension, any one of the front wheel-side suspension and the rear wheel-side suspension discharges the hydraulic fluid to the first tank, and the other of the front wheel-side suspension and the rear wheel-side suspension discharges the hydraulic fluid into the second tank by the pressurization device.

An electromagnetic suspension device includes: an electromagnetic actuator that generates a driving force related to vibration damping of a vehicle body by an electric motor; a rotational angle acquisition unit that acquires a rotational angle of the electric motor; a rotational angle acceleration calculation unit that calculates a rotational angle acceleration of the electric motor based on the rotational angle; ECU that performs driving force control including inertia compensation control of the electromagnetic actuator based on the rotational angle acceleration; and a relative speed calculation unit that acquires a relative speed between above- and below-spring members. In an area in which a relative speed exceeds a predetermined relative speed threshold, the ECU corrects an amount of inertia compensation so that the amount of inertia compensation is decreased, as compared with an area in which a relative speed value is the relative speed threshold or less.
