  • Patent number: 10836372
    Abstract: A hybrid vehicle control system and method include a controller programmed to, while a transmission is in PARK or NEUTRAL, start an engine, close a disconnect clutch selectively coupling the engine to an electric machine, and control the electric machine to charge a traction battery in response to the accelerator pedal position exceeding an idle position and being less than a threshold. The controller controls transmission impeller speed in response to accelerator pedal position exceeding the threshold to allow revving the engine in response to accelerator pedal. A method for controlling a hybrid vehicle includes starting an engine, closing a clutch between the engine and an electric machine, and controlling the engine and the electric machine to either: i) charge a traction battery or ii) rev the engine based on accelerator pedal position relative to a threshold above an idle position while the transmission is in PARK or NEUTRAL.

  • Patent number: 10833081
    Abstract: Structures and methods that facilitate forming isolated contacts in stacked vertical transport field effect transistors (VTFETs). A pair of stacked VTFETs are formed on a substrate and isolated from each other. A via or hole is formed to extend to a drain of the second VTFET and a source of the first VTFET. The via is filled with a metal below the first VTFET to form the second contact. The second contact is capped with a non-conductive material and the remaining portion of the via is filled with metal to form the first contact. Alternatively, a via or hole is formed to extend to a source of the second VTFET and a source of the first VTFET. The second contact may serve as a local interconnect, a ground, or a voltage source connection.

  • Patent number: 10829099
    Abstract: Certain driver-assist features of a vehicle require incredibly precise longitudinal control of the vehicle. Achieving the precise control requires up-to-date knowledge of performance parameters of a brake system of the vehicle, which may vary extensively based on a wide set of influences outside the control of the brake system. The present disclosure proposes techniques to determine these parameters, for example, by stopping the vehicle early in maneuvering in order to study the brake performance, so that precise longitudinal control of the vehicle may be realized.
