  • Method and system for boost pressure control
    Patent number: 10024227
    Abstract: Methods and systems are provided for controlling boost pressure in a staged engine system comprising a turbocharger and an upstream electric supercharger based on altitude. During vehicle operation at higher altitudes, where vacuum availability for wastegate actuation is limited, boost pressure may be provided by operating the electric supercharger more aggressively. The wastegate may be used for boost control once the vacuum reserve is replenished.

  • Sludge detection and compensation for the continuously variable compressor recirculation valve
    Patent number: 10001089
    Abstract: Methods and systems are provided for improving boost pressure control by adjusting a variable compressor recirculation valve. In one example, a method may include adjusting a position of a continuously variable compressor recirculation valve based on amount of sludge accumulation on the valve. The amount of sludge accumulation may be estimated based on a difference between total intake flow downstream of a compressor recirculation passage outlet but upstream of the passage, and total engine flow entering engine cylinders.

  • ADAPTING ENGINE-ON TIME TO DRIVER AGGRESSIVENESS IN A HYBRID VEHICLE
    Publication number: 20180099658
    Abstract: A vehicle includes an engine and at least one controller. In response to a change in a rate of change of a driver control input to the vehicle, the at least one controller is programmed to alter conditions under which the engine will be started and stopped such that engine-on time increases due to the rate increasing and decreases due to the rate decreasing.

  • Methods and system for determining compressor recirculation valve sludge
    Patent number: 9903288
    Abstract: Systems and methods for determining the presence or absence of deposits that may accumulate within a compressor recirculation valve positioned in parallel with a turbocharger compressor are presented. The systems and methods adjust actuators to maintain engine operation such that it may be more difficult for a driver to become aware that a compressor recirculation valve diagnostic is being executed.
