摘要： A vent assembly is disposed within an interior space of a vehicle for opening and closing fluid communication between the interior space and an exterior of the vehicle. The vent assembly includes a housing defining a plurality of openings and a plurality of vanes disposed in the openings. An actuator mechanism moves the vanes between an open position and a closed position, and includes a shaped memory alloy (SMA) member for actuating the vanes between the open and closed positions. The SMA member is activated when a hatch of the vehicle is open to move the vanes into the open position and thereby open fluid communication between the interior space and the exterior to alleviate excessive air pressure buildup during closure of the hatch.

摘要： An on-vehicle DC/DC converter transforms high-voltage electric power originating from an on-vehicle high-voltage source to low-voltage electric power at a regulated voltage level. The low-voltage electric power is distributed by a low-voltage bus. A method for operating the DC/DC converter includes monitoring a state of charge and a temperature of a low-voltage battery connected to the low-voltage bus, setting a DC/DC converter command to a nominal voltage level as a function of the state of charge and temperature of the low-voltage battery, monitoring a total low-voltage electric load, and adjusting the DC/DC converter command to a minimum low-voltage reference voltage when the vehicle is operating below a predetermined speed and the total low-voltage electric load is greater than a predetermined load.

摘要： A linear actuator associated with an actuator system for a device includes a wire cable fabricated from an active material. The linear actuator couples to the device and to the moveable element. The active material induces strain in the linear actuator in response to an activation signal. The linear actuator translates the moveable element relative to the device in response to the induced strain. An activation controller electrically connects to the linear actuator and generates the activation signal. A position feedback sensor monitors a position of the moveable element.

摘要： A hybrid powertrain system includes an electric motor/generator unit having a multiphase asynchronous AC machine electrically connected to a multiphase bridge inverter. A high-voltage capacitor is electrically connected between positive and negative sides of a high-voltage DC power bus. High-voltage DC bus pre-charge circuits are electrically connected between gate drive bias power supplies and the multiphase bridge inverter. A low-voltage battery electrically charges the high-voltage DC link capacitor via the gate drive bias power supplies and the high-voltage DC bus pre-charge circuits when the high-voltage energy storage system is disconnected from the high-voltage DC power bus.

摘要： Certain circuit faults in a phase of a multi-pole, switched reluctance, rotary electrical machine are detected; and the machine is selectively operated with a detected circuit fault when the nature of the fault permits continued operation of the phase and the operation of the phase is desirable. The fault may be one of certain short or open circuits in which at least one of the two current controlling electronic switches is operable to control phase current within predetermined limits. In the continued operation when a fault is detected, (1) the phase current is switched off earlier than it would be in the absence of the fault and/or (2) the maximum phase current is reduced compared with that permitted in the absence of the fault; and either or both of these modifications may be a function of motor speed. If the circuit fault adversely affects current control by an electronic switch normally controlling current level, another electronic switch is substituted for current control.
