  • Publication number: 20230219554
    Abstract: Responsive to a user request, a controller operates an engine of a vehicle while parked to charge a traction battery to a target state of charge that exceeds a maximum state of charge limit, used during drive of the vehicle by an electric machine, in advance of a predefined period of time.

  • Patent number: 11590959
    Abstract: A system and method for controlling a hybrid vehicle having an engine, a traction motor, and an automatic step-ratio transmission having a plurality of selectable discrete gear ratios, a torque converter, and sharing a common cooling fluid or oil with the traction motor, include a controller configured to shift the automatic step-ratio transmission to neutral in response to vehicle speed being below a threshold with the engine idling while temperatures of at least two of: the traction battery, the electric machine, and the transmission are above associated thresholds to reduce heat generation by the torque converter due to oil shear with the torque converter stalled. The controller may shift the transmission to drive in response to release of a brake pedal. A neutral shift may also be performed in response to high-voltage accessory loads or on-board generator loads exceeding a threshold.

  • Patent number: 11524582
    Abstract: A vehicle includes a battery, an electric machine, an electrical outlet, and a controller. The electric machine is configured to charge the battery. The electrical outlet is configured to draw power from the battery to power an external device. The controller is programmed to adjust a rate at which the electric machine charges the battery based on a power consumption at the electrical outlet exceeding a threshold and a battery degradation value.

  • Publication number: 20020080195
    Abstract: The present system and method is directed to an interactive navigation system and method for exploring or browsing digital content data that can be spatially structured such that content pages can be located relative to one another. Once a page arrangement layout is completed, a navigation bar in conjunction with an underlying scrolling engine allow fast access to any section of the information space while maintaining an intuitively correct spatial metaphor. Thus, as the user manipulates the navigation bar, the scrolling engine moves the user to the new information content area in a visually intuitive manner while the intermediate content is displayed on a screen.
