    摘要： A method to control a hybrid electric vehicle (HEV) having a compression ignition engine includes operating the engine based on an engine-on request and performing an exhaust aftertreatment procedure based on a completion time for the aftertreatment procedure compared to a predicted engine-on time determined using a driving pattern. An HEV is provided with a compression ignition engine with an aftertreatment system, and a controller. The controller is configured to: (i) operate the engine based on an engine-on request, and (ii) perform an exhaust aftertreatment procedure for the vehicle based on a completion time for the aftertreatment procedure compared to a predicted engine-on time determined using a driving pattern. A computer readable medium having stored data representing instructions executable by a controller to control a vehicle is provided with instructions for operating the engine based on an engine-on request, and instructions for performing an exhaust aftertreatment procedure.

    摘要： A method to control a hybrid electric vehicle includes operating a compression ignition engine based on an engine-on request, and performing an exhaust aftertreatment procedure when a fraction of an engine-on time is greater than an aftertreatment condition threshold. A vehicle has a compression ignition engine with an exhaust aftertreatment system, and a controller. The controller is configured to: (i) operate the engine based on an engine-on request, and (ii) perform an exhaust aftertreatment procedure for the vehicle when an engine-on fraction for a designated time is greater than an aftertreatment condition threshold. A computer readable medium having stored data representing instructions executable by a controller to control a vehicle includes instructions for operating the engine based on an engine-on request, and instructions for performing an exhaust aftertreatment procedure for the vehicle when an engine-on time fraction is greater than an aftertreatment condition threshold.

    摘要： A system and method for controlling a hybrid electric vehicle powertrain having an engine defining one power source, and a traction motor and electrical storage device defining another power source include inhibiting a stopping and a starting of the engine based upon an unintended tip-out event and an unintended tip-in event, respectively. The total power demand and the available electric power are determined. The total power demand is filtered. The engine is prevented from being pulled-up or pulled-down based upon a difference between the total power demand and the filtered power demand being exceeding a threshold. However, if the difference exceeds the threshold, and if the available electric power exceeds the total power demand, then the engine is permitted to pull-up or pull-down.

    摘要： A vehicle and a vehicle system are provided with a controller that is configured to generate output indicative of a kinematic road gradient estimation using an extended Kalman filter. The extended Kalman filter includes a system input based on a longitudinal acceleration and an acceleration offset, and a system output based on a predicted vehicle speed. The acceleration offset is based on at least one of a lateral velocity, a lateral offset, and a vehicle pitch angle. The controller is further configured to generate output indicative of a kinematic quality factor corresponding to an availability of the kinematic road gradient estimation.
