  • Patent number: 10975790
    Abstract: Systems and methods are provided for using an electric machine as a generator to control boost during an engine cold start. In one example, a method may include receiving a request to increase an engine load during the engine cold start, determining an available capacity of a battery, operating the electric machine as a generator to increase the engine load with an electrical load, and responsive to the available capacity of the battery being less than a charge threshold, charging the battery with the electrical load while generating an increased boost pressure with an electric boosting device by powering the electric boosting device via the battery, and coordinating an amount of the increased boost pressure to compensate the electrical load. By increasing the engine load during the engine cold start, an exhaust gas temperature may be increased to achieve catalyst light-off.
