    摘要: A circuit that detects if contacts in an HV contactor have been welded or stuck closed. The circuit includes a controller that generates a short duration pulse signal that closes a driver switch and allows current flow through a coil in the HV contactor. The current flow is converted to a voltage by a sensor, where the voltage is received by the controller. The controller uses the voltage, such as by comparing the voltage to a stored representative voltage of the coil current for when the HV contactor is open, to determine whether the HV contactor is closed, and possibly welded or stuck closed, or partially closed. The sensor can be the driver switch or another device, such as a resistor.

    摘要: Cathode-anode voltage across free-wheeling diodes in an active rectifier is used in the determination of switching points when the free-wheeling diode is forward biased. Hysteretic switching is accomplished through the selection of conductive and non-conductive switching threshold. The switching thresholds are further selected to prevent voltage oscillations at zero current crossings and reduce delays during deactivation to prevent cross-conduction.

    摘要: A vehicle includes a direct start engine, an automatic transmission having a threshold fluid pressure sufficient for enabling operation of the transmission when the engine is off, a controller, and a fuel delivery system. The controller determines the presence of predetermined engine states, and optimizes a stop-and-go functionality of the engine. The fuel delivery system includes a motor and an integrated pump assembly having a secondary high-pressure (HP) fuel pump which is selectively connectable to a rotatable shaft of the motor, and a secondary low-pressure (LP) fluid pump which is continuously connected to the shaft. The motor continuously energizes the secondary LP fluid pump via the rotatable shaft to thereby maintain the threshold fluid pressure during a first or second engine state, and selectively energizes the secondary HP fuel pump via the rotatable shaft to maintain the threshold fuel pressure during the second engine state.

    摘要: A vehicle includes a direct-start engine and a fuel rail with a threshold fuel pressure, a transmission having a threshold fluid pressure, and a fuel delivery system. The system has a controller, a motor having a shaft, and an integrated pump assembly including a high-pressure (HP) fuel pump and a low-pressure (LP) fluid pump each connected to the shaft. Threshold pressures are maintained during the predetermined engine state, which includes an engine idling and an engine cranking state. A method for providing stop-and-go functionality in a vehicle having a direct-start engine includes detecting a current engine state, rotating a motor shaft to energize a secondary HP fuel pump at a first threshold pressure during engine cranking, and rotating the shaft to energize an LP fluid pump at a second threshold pressure during engine idling and engine cranking. The secondary pumps can also be used when primary pumps are temporarily inoperable.

    摘要: A damper assembly is provided including a linear to rotary motion conversion mechanism having an outer tube member. An inner tube member is reciprocally movable and at least partially disposed within the outer tube member. The inner tube member is adapted for linear translation in a first and a second direction. A rotatable shaft is disposed within the inner tube member. The translation of the inner tube member produces a rotation of the shaft. Also included within the damper assembly is a damping mechanism having a rotor fixed to the shaft. A coil is configured to generate an electromagnetic field in response to an applied current. A magneto-rheological fluid is in contact with the rotor, and has a variable viscosity in the presence of the electromagnetic field that, in turn, provides variable resistance to rotation of the rotor and translation of the inner tube member within the outer tube member.

    摘要: Systems, methods and devices are described for controlling a vehicle electrical generator. A regulator for controlling a generator in response to an input signal received from a control module suitably includes a discriminator module, a processing module and a switching circuit. The discriminator determines whether the regulator is operating in voltage or torque control mode. If the input signal is a voltage control, the output generator produces a modulation signal to produce a desired voltage between two battery terminals. If the input signal is a torque control, the output generator produces one or more modulation signals (e.g. pulse width modulation signals) to control the torque of the generator. The modulation signals are applied across a field coil or other controllable element of the generator by a switching circuit that applies positive and/or negative voltage from the battery terminals as appropriate.
