  • Patent number: 11548485
    Abstract: This disclosure relates to an electrified vehicle configured to address an excess braking request, such as a braking request in excess of what can be met by an energy recovery mechanism, by selectively increasing the drag of the electrified vehicle. A corresponding method is also disclosed. An example electrified vehicle includes an energy recovery mechanism, an actuator configured to adjust a position of a moveable component influencing a drag of the electrified vehicle, and a controller. The controller is configured to instruct the energy recovery mechanism to meet a braking request and, when the braking request cannot be met by the energy recovery mechanism, the controller is configured to instruct the actuator to adjust the position of the moveable component to increase the drag of the electrified vehicle.

  • Patent number: 9637112
    Abstract: A hybrid vehicle includes a traction battery having a battery fan, an engine, an electric machine coupled to the battery, and a controller or at least one powertrain module having a controller. The controller is programmed to respond to a change in a user selected powertrain operating mode to a performance mode. This change may occur while a pedal demand is generally constant. The controller may increase an available power of the battery to drive the electric machine without altering state of charge operating limits of the battery. The increase in available power of the battery may include increasing a state of charge of the battery or reducing the battery temperature such that a current may flow from the battery for a longer time period. Also, the overall available power for the vehicle may include operation of the engine at a higher rotational speed.

  • Publication number: 20170057322
    Abstract: A method of controlling a cabin temperature of a hybrid or a start-stop equipped vehicle when idling is provided. The method includes the steps of: (a) monitoring a state of the vehicle transmission; (b) sensing a temperature within the cabin of the vehicle; and (c) overriding an initial setting of a climate control system of the vehicle after the state of the vehicle transmission has been in park for a predetermined period of time and the sensed cabin temperature is within a predetermined temperature range. The initial setting of the climate control system may be adjusted to maintain the cabin temperature within the predetermined temperature range. A vehicle operator may be informed of the override via wireless communication or a visual indication.
