摘要： An analytical methodology for the specification of progressive optimal compression damping of a damper of a suspension system to negotiate a multiplicity of severe events, yet provides very acceptable ride quality and handling during routine events. The damping response of the damper is optimized based upon a progressive optimal constrained events damping function derived from a low envelope curve incorporated with a predetermined damper force acting on the wheel center below a predetermined wheel center velocity, u1, based on ride and handling considerations for a given vehicle or vehicle model according to the prior art methodology, whereby the low envelope curve is constructed utilizing a one degree of freedom nonlinear mechanical system model or a quarter car nonlinear mechanical system model.

The coupling includes a stator, a rotor having a rotational degree of freedom with respect to the stator and configured for physical communication with the shaft, and a magnetic field generator. The stator and rotor define an annular space therebetween and are coupled via a MR fluid disposed within the annular space. The magnetic field generator is in field communication with the MR fluid and is disposed to produce a substantially radially directed magnetic field across the annular space. The rotor is rotationally responsive to the application of a magnetic field at the MR fluid.

摘要： A generator field regulator circuit communicates with a field winding of a Lundell machine and includes a first transistor. A second transistor has a source that communicates with a drain of the first transistor and a drain that communicates with one end of the field winding. A free-wheeling diode communicates with the drain of the first transistor and a source of the second transistor. An overvoltage detection circuit modulates a gate of the second transistor. A pulse width modulation (PWM) circuit modulates a gate of the first transistor to maintain generator rectified voltage at a nominal level. The overvoltage detection circuit outputs an overvoltage shutdown signal to the PWM circuit during a full-load dump mode to turn off the first transistor, which turns off the second transistor. The overvoltage shutdown signal is disabled when a terminal voltage of a generator falls below a predetermined voltage.

摘要： A hydraulic mount for automotive engine and powertrain applications includes an elastomer body, a base and a partition interposed the body and the base to form a fluid-pumping chamber and a reservoir. Circumferentially spaced axial extending holes or slots or an annular orifice track are formed in the partition together with a magnetic coil operable to impose a magnetic field on the holes, slots or orifice track to control the shear properties of a magnetorheological (MR) fluid in the pumping chamber and reservoir. An elastomeric decoupler member is in communication with at least one of the pumping chamber and the reservoir to reduce the mount dynamic stiffness for isolating low-displacement relatively high-frequency vibrations. Vibrations of multiple frequencies may be isolated by tuning the mount with a controller.

摘要： A method and device for regulating charging and discharging current through a battery pack. Two or more battery packs are connected in parallel to an inverter, such that the inverter can use grid power to charge the battery packs or the battery packs can provide AC power through the inverter. A current balancing circuit device is placed in series with each battery pack and is used to regulate the current through the battery pack so that none of the battery packs is excessively charged or discharged. The current balancing circuit includes two field effect transistors (FETs) arranged in series and in opposite directions, where one FET controls charging current and the other controls discharging current. The balancing circuit also includes a current sensor, and uses proportional-integral control to provide a signal to the FETs such that the actual current flowing through the circuit is regulated to a target current value.

摘要： A method of reducing glare may include sensing a first light source with a second vehicle, and sensing a second light source with a first vehicle and oscillating a first light source ICF between a substantially opaque state and a substantially clear state on a first schedule. A second windscreen ICF may be oscillating between the substantially opaque state and the substantially clear state on a second schedule different from the first schedule. A position of the light source may be sensed and an eye position of the occupant estimated. An intersecting region of the selectively-darkenable ICF, which is located substantially along a line from the position of the light source to the eye position, is calculated. The intersecting region of the ICF is darkened, such that a reduced amount of light from the light source passes through the intersecting region.
