摘要:
A powertrain for a hybrid electric vehicle (HEV) such as a plug-in hybrid electric vehicle (PHEV) includes an engine, a fuel tank, a battery, and a controller. The controller is configured to determine a distance to empty value as a sum of fuel in the fuel tank and a battery equivalent amount of fuel, the sum multiplied by an average fuel economy of the PHEV based on a driving condition of the vehicle.

A stability control system for a vehicle that has an electric traction motor that provides torque to an axle through a differential. The traction motor responds to an instability event that is sensed by sensors on the vehicle by initially reducing the torque provided to the traction wheels to regain steering control. The traction motor then pulses increased torque in sequence with the application of braking force to provide enhanced direct yaw moment control.

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.

A method to control a vehicle includes assigning a predicted driving pattern to a predicted path for the vehicle, and providing a range for the vehicle using the predicted energy efficiency and an amount of energy available to the vehicle. The predicted driving pattern has an associated predicted energy efficiency. A vehicle includes a propulsion device coupled to wheels of the vehicle via a transmission, and a controller electronically coupled to the propulsion device. The controller is configured to: (i) assign a predicted driving pattern to a predicted path for the vehicle, the predicted driving pattern having a predicted energy efficiency, and (ii) provide a range for the vehicle using the predicted energy efficiency and an amount of energy available to the vehicle.

A computer-implemented method includes determining that a vehicle powertrain feature is engaged. The method further includes relaying, to a remote computing source, a request for a computation to be performed relating to the engaged powertrain feature. The method additionally includes receiving a result of the computation at a vehicle computing system and transferring the result of the computation to a powertrain for use in controlling the powertrain feature.

摘要:
A path-dependent control of a hybrid electric vehicle (HEV) includes segmenting an original route into segments. A virtual route based on the remaining portion of the original route is generated once the HEV reaches a current segment of the original route. The virtual route includes a first segment corresponding to the current segment of the original route and a last segment representing at least two other segments of the remaining portion of the original route. Battery SoC set-points for the segments of the virtual route are generated. The vehicle is controlled according to the battery SoC set-point for the first segment of the virtual route as the vehicle travels along the current segment of the original route.
