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 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 system and method for managing faults occurring in a power steering system in a vehicle is disclosed that has particular application for an MRHPS system to provide reliable functioning of the power steering system. The method includes detecting a fault condition in the MRHPS system and selecting a safe mode from a plurality of predetermined safe modes based on the fault condition. The plurality of predetermined safe modes include a normal operation mode, an engine speed follow mode, a manual mode, a fixed duty cycle mode and a voltage control mode. If a fault condition is detected, the method applies the safe mode to manage the fault condition.

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.
