    摘要： A hybrid electric vehicle system comprises an internal combustion (IC) engine and an electric engine providing power to a drive shaft of the vehicle. The IC engine receives a fuel from a fuel tank. Exhaust gases from the IC engine are treated at an exhaust treatment apparatus including a reagent tank containing a reagent. A controller monitors a quality of the fuel in the fuel tank and the reagent in the reagent tank and if needed, initiates fuel degradation reduction event or a reagent degradation reduction event. These events can include running the IC engine even if a battery supplying power to the motor is not discharged. The fuel degradation reduction event includes dosing the fuel tank with an antioxidant to reduce the rate of degradation of the fuel.

    摘要： The present disclosure provides an engine stop/start control system for a vehicle comprising a first engine restart module configured to set a restart frequency and duration of an engine in response to a sensed ambient temperature, a second engine restart module configured to control the engine in response to a sensed characteristic temperature associated with the engine, a third engine restart module configured to control the engine in response to occurrence or non-occurrence of at least one expected charging event along a predefined route, a fourth engine restart module configured to control the engine in response to a state-of-charge of an energy storage device, and a route optimization module configured to set and adjust a proposed route to a destination that results in reduced engine usage.

    摘要： Systems and methods for managing an environment comfort system includes a control system. The control system is communicatively coupled to a location positioning system. The control system is structured to determine a first time parameter corresponding to a vehicle proximate to a path location, determine a second time parameter corresponding to a path schedule, determine a stop duration corresponding to the vehicle based, at least in part, on the first time parameter and the second time parameter, and generate a command structured to manage an environment comfort system in response to movement of the one or more vehicle components between a current performance level and an adjusted performance level based on the stop duration determined.

    摘要： Systems and methods for managing an environment comfort system includes a control system. The control system is communicatively coupled to a location positioning system. The control system is structured to determine a first time parameter corresponding to a vehicle proximate to a path location, determine a second time parameter corresponding to a path schedule, determine a stop duration corresponding to the vehicle based, at least in part, on the first time parameter and the second time parameter, and generate a command structured to manage an environment comfort system in response to movement of the one or more vehicle components between a current performance level and an adjusted performance level based on the stop duration determined.

    摘要： A method for operating an engine based on cabin temperature includes determining a quantity of fuel in a fuel tank, determining a minimum amount of fuel to remain in the fuel tank, receiving a predetermined cabin temperature value, calculating an engine idle time in response to the minimum amount of fuel and the predetermined cabin temperature value, and controlling engine starting and stopping in response to the engine idle time and the predetermined cabin temperature value.
