摘要： Systems and methods for performing closed-in-bore diagnostics for a hybrid vehicle are presented. In one example, select operating conditions may be evaluated before closed-in-bore diagnostics may be initiated. In addition, charging of one or more batteries may be reduced to ensure that an engine throttle may operate with a small opening amount to evaluate the presence or absence of sludge in the engine throttle.

摘要： Systems, apparatus, and methods are presented to transfer energy between an energy storage device (ESD) at an electrified vehicle (EV) and an AC or DC external load such as an electric grid, appliance or power tool. A portable EVETA can engage an EV charge inlet couple an EV, and can provide an AC outlet, a grid interface and a DC connector for coupling external loads. An EVETA can be used at a remote construction site or campsite to power high current equipment, obviating the need to transport an electric generator. An EVETA can be configured for data and control communication with the EV to coordinate energy transfer. An EVETA can receive a predetermined ESD state of charge limit so that the transfer process can be terminated to preserve sufficient charge for EV return to a desired destination. A human machine interface enables user input reception and information display.

摘要： Methods and systems are provided for electrical power distribution. In one example, a system includes plurality of electric consumers comprising one or more operating modes with different levels of power consumption, an energy storage and an electric machine arranged in the vehicle and configured to provide energy to the energy storage device or power to the electric consumers and torque to wheels of the vehicle, a power allocating device coupled to the energy storage device and the plurality of electric consumers, and a controller configured to maintain two indices for allocating power to the plurality of electric consumers, wherein a first index comprises a first power allocation strategy based on power from only the energy storage device and a second index comprises a second power allocation strategy based on power from the energy storage device and the electric machine.

摘要： A drive system for an electric vehicle includes an input capacitor selectably coupled to a DC power source (e.g., battery) by a contactor. A variable voltage converter couples the input capacitor to a main link capacitor, and an inverter couples the main capacitor to a machine load (e.g., motor and/or generator). During a normal or emergency shutdown, the contactor is opened. In order to quickly discharge the input capacitor when the contactor opens, A) the converter operates in a boost mode to transfer charge from the input capacitor to the main capacitor until the input capacitor discharges to less than a threshold voltage, B) the converter deactivates to prevent transferring charge from the main capacitor to the input capacitor, and C) the main capacitor can then be discharged through the inverter.

摘要： Systems and methods for operating a driveline of a hybrid vehicle are presented. In one example, torque capacity of a driveline disconnect is coordinated with torque control of an electric machine immediately following engine starting. The electric machine and the driveline disconnect clutch may assist starting of an engine, or alternatively, the engine may be started via a starter motor.

摘要： Systems and methods for transitioning a hybrid vehicle from park or neutral to drive or reverse are presented. In one example, a requested engine speed is adjusted in response to a transmission disengaging indication and a transmission disengaging timer when a transmission is being disengaged from a gear. In another example, the requested engine speed is adjusted in response to a transmission engaging indication and a transmission engaging timer when the transmission is being engaged to a gear.
