    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 opened 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： A vehicle system includes a position sensor, a current supply module, and a mode indicator module. The position sensor includes: an electromagnet (EM) that generates a magnetic field proximate to one of an intake valve and an exhaust valve of an engine; and a Hall-effect sensor that generates a position signal indicating a position of the one of the intake valve and the exhaust valve based on the magnetic field. The current supply module supplies current to the EM. The mode indicator module indicates whether the one of the intake valve and the exhaust valve is being actuated in a low lift mode or a high lift mode based on the position signal.

    摘要： A system according to the principles of the present disclosure includes a cylinder activation module and a spark timing module. The cylinder activation module selectively deactivates and reactivates a cylinder of an engine based on a driver torque request. When the cylinder is deactivated, the spark timing module selectively increases an amount by which spark timing of at least one active cylinder of the engine is retarded based on noise and vibration generated by the engine when the cylinder is deactivated.

    摘要： A variable current gate driver for a transistor includes a first current control device having a first controllable output current. The first current control device is electrically connected between a first bus and an activator of the transistor, and a second current control device having a second controllable output current. The second current control device is electrically connected between the activator of the transistor and a second bus. A controller is operatively connected to the first and second current control devices to control the first and second controllable output currents to control the first and second current control devices to control activation of the transistor via the activator. The controller is operative to control the first and second current control devices to control a slew rate of the transistor.

    摘要： A fuel control system of a vehicle includes an injection control module and a command module. The injection control module determines a first target amount of fuel for a combustion event of an engine. A command module selectively command the injection control module to provide two fuel injections when a torque request decreases. In response to the command, the injection control module: determines second and third target amounts of fuel based on the first target amount; provides a first fuel injection during the combustion event based on the second target amount; and provides a second fuel injection during a compression stroke of the combustion event based on the third target amount.
