    摘要： A vehicle powertrain includes an engine, an electric machine operable to output torque to at least one vehicle wheel, and an electric power source operable to provide electric power to the electric machine. A method for optimizing powertrain efficiency includes generating a plurality of three-dimensional maps of optimized engine speeds for combinations of vehicle power and vehicle speed at a plurality of predetermined powers of the electrical power source. Each of the maps corresponds to one of the predetermined powers of the electrical power source. The maps are used to determine an optimized engine speed for a given power of the electrical power source, a given vehicle power and a given vehicle speed.

    摘要： A hybrid electric vehicle powertrain having a mechanical power source and an electro-mechanical power source, including a generator, a motor and a battery. Driving torque developed by the mechanical power source is delivered through one clutch of a geared transmission to a power output shaft. The electric motor of the electro-mechanical power source delivers driving torque through a second clutch of the geared transmission. A mechanical reverse drive torque is used to improve reverse drive performance. A reduction in duration of operation in a negative power split during a driving event is achieved to improve vehicle powertrain efficiency. A series drive is available as the mechanical power source drives the generator to charge the battery, which drives the motor. The generator may act as an engine starter motor.

    摘要： A method for controlling engine idle in a vehicle having a motor connected to the engine through a power transfer unit is provide. Upon receiving a neutral command, the engine torque is commanded to approximately zero. The motor torque is adjusted to maintain an approximately constant engine speed as the engine torque is reduced. The torque from the engine transferred to the vehicle wheels is at or near zero. When the torque at the vehicle wheels is non-zero, a second motor is used to cancel the torque output from the engine so the torque at vehicle wheels is zero. When the engine torque has reached approximately zero, or when a predetermined amount of time has past, both motors are shutdown, and all of the remaining engine torque is transferred to the first motor through the power transfer unit.

    摘要： A method for determining a route for a vehicle includes receiving input indicative of a driver's dynamic control of the vehicle, determining the driver's driving style based on the input, and selecting values of parameters representing the driver's anticipated dynamic control of the vehicle based on the driving style. The method also includes identifying a plurality of candidate routes between an origin and destination, partitioning each of the candidate routes into a set of predefined route patterns, and determining an energy usage associated with each of the candidate routes based on the selected values and the set of predefined route patterns defining the candidate route. The method further includes identifying the candidate route having the minimum energy usage and providing output describing the route having the minimum energy usage.

    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.
