  • Publication number: 20180347530
    Abstract: An automatic engine stop-start system of a vehicle having an engine includes a controller in signal communication with the engine and configured to command automatically stopping and starting the vehicle engine, a first sensor in signal communication with the controller and configured to generate a first signal indicative of a grade of a road the vehicle is located on, and a master brake cylinder having a pressure sensor in signal communication with the controller, the pressure sensor configured to generate a pressure signal indicative of a master cylinder brake pressure. The controller is further configured to determine a pressure threshold based on the first signal and the pressure signal. When the pressure signal exceeds the pressure threshold, thereby indicating a driver is releasing a brake pedal of the vehicle, the controller commands automatically restarting the vehicle engine.

  • Patent number: 8513930
    Abstract: Embodiments of an active power switch topology for a switching regulator are provided herein. The embodiments of the active power switch topology use two or more active power switches in parallel instead of a single active power switch, as found in conventional implementations. The active power switches are controlled such that they turn-on and -off in a manner that reduces parasitic voltage spikes associated with conventional switching regulators, while not degrading efficiency or other parameters associated with the switching regulator. The active power switch topology can be beneficially used within many switching regulators (e.g., buck, boost, or buck-boost) and, in particular, within hard-switched switching regulators that include active power switches integrated on chip.

  • Patent number: 7903681
    Abstract: A method of distributing a common time reference within a distributed architecture includes one or more of the following: generating at least one electrical pulse at a central entity; distributing the at least one electrical pulse to a subassembly; receiving the at least one electrical pulse at the subassembly; recording a reception counter value corresponding to a value of a local frequency counter when the at least one electrical pulse is received at the subassembly; querying the central entity to obtain a generation time value corresponding to a time at which the at least one electrical pulse was generated; and determining a global time value using the generation time value, the reception counter value, and a current counter value of the local frequency counter.
