  • Control strategy for plug-in hybrid electric vehicle
    Patent number: 10543830
    Abstract: A method of controlling a plug-in hybrid electric vehicle including an electric propulsion system, an engine, and a catalytic converter associated with the engine, the method comprising: monitoring a state of charge of a battery of the vehicle when in a charge depletion mode; determining a rate of depletion of the state of charge; estimating from the rate of depletion a duration of a depletion period representing the time remaining until a minimum state of charge of the battery will be reached; determining a duration of a warming period of the catalytic converter; comparing the duration of the depletion period and the duration of the warming period; and activating the engine if the duration of the depletion period is less than or equal to the duration of the warming period.
