  • Methods and systems for airflow control
    Patent number: 9650973
    Abstract: Methods and systems are provided for airflow control in an engine system which includes a throttle turbine generator including a turbine and a turbine generator. In one example, a method may include adjusting an angle of a throttle positioned in an engine inlet passage based on a desired airflow by taking into account the effects on the throttle angle due to rotation motion of the turbine, thereby accurately controlling airflow to the engine system. The method may further include predicting an airflow to the engine system based on the position of the throttle, thereby accurately monitoring torque of the engine system.

  • Inhibit engine pull-down based on past driving history
    Patent number: 9604635
    Abstract: A hybrid vehicle includes an engine and a motor that are both capable of powering the wheels. While a vehicle is being driven, the vehicle's driving condition data is monitored. The driving condition data can include steering wheel angle or position, accelerator pedal position, driver torque or power demands, or road grade or incline. The vehicle includes a controller with a specific control scheme to receive the driving condition data, and subject the data to a moving average or a weighted moving average. Based on the averaged driving condition data, the engine is inhibited from stopping under certain conditions to reduce the frequency of the engine turning on and off.
