A vehicle includes an electrified propulsion system powered by a traction battery over an electrical distribution system (EDS) and a controller programmed to monitor at least one of a current flow and a temperature at a plurality of locations throughout the EDS. The controller is also programmed to implement at least one mitigation action over a predetermined time window in response to detecting a filtered current value exceeding a threshold.

Electrified vehicle electrical distribution system component protection systems and methods

A method for managing power in a hybrid electric vehicle powertrain having multiple components including at least two of a group comprising an engine, a motor, a generator and a high voltage battery includes computing power losses for the individual components. An engine operating speed and torque for a given vehicle speed and total power command is determined so that total power losses for powertrain components are minimized.

Optimal engine operating power management strategy for a hybrid electric vehicle powertrain

An exemplary method includes using a controller to automatically operate a vehicle in an electric mode when an actual speed of the vehicle is at or below a set threshold, and to automatically operate the vehicle in a hybrid mode when the actual speed is above the set threshold. The method further including adjusting the set threshold using a selector device such that the set threshold is changed without influencing the actual speed. Another exemplary method includes using a controller to automatically initiate a transition of a vehicle from an electric mode to a hybrid mode, or from the hybrid mode to the electric mode. The controller initiates the transition in response to a comparison of a state of charge of a battery of the vehicle to a threshold state of charge that is configured to be adjusted by an operator.

Selective electric mode for electric vehicle

A plugin hybrid electric vehicle includes an internal combustion engine, a battery, an electric machine, and a controller. The vehicle is operable in a primary electric vehicle driving mode (EV mode) and in a hybrid electric vehicle driving mode (HEV mode). The controller is programmed to receive input from the driver representing a desired operating mode and a desired energy reservation. If the desired operating mode is HEV mode, then a state of charge (SOC) offset is established as the smaller of a maximum SOC offset and an allowable SOC offset, otherwise, the SOC offset is established based on the desired energy reservation. The vehicle is operated based on the SOC offset.

Plug-in hybrid electric vehicle battery state of charge hold function and energy management

An example method includes operating an electric vehicle in an electric mode when a speed of the electric vehicle is at or below a threshold speed, and operating the electric vehicle in a hybrid mode when the speed of the electric vehicle is above the threshold speed. The threshold speed is an operator-adjustable threshold speed. Another example method includes operating an electric vehicle in an electric mode when a state of charge of a battery of the electric vehicle is at a threshold state of charge, and operating the electric vehicle in a hybrid mode when the state of charge of the battery is at or below the threshold state of charge.

A powertrain includes a planetary gearset including an input connected to a shaft driveably connected to an engine, a second input driveably connected to an electric machine, and an output driveably connected to a countershaft, a clutch for releaseably connecting the countershaft and the input shaft through a first pair of meshing gears, and a brake for releaseably holding the input shaft and the input against rotation.

Powersplit powertrain for a hybrid electric vehicle

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.

A hybrid-electric powertrain and control method for a vehicle having forward traction wheels and rearward traction wheels in an all-wheel drive configuration. An engine and an electric motor deliver power through delivery paths to the traction wheels. The power delivery paths may have multiple ratio gearing so that more power can be delivered mechanically to improve powertrain performance and to allow the electric motor size to be reduced. The powertrain includes a controller for automatically balancing power distribution to the forward and rearward traction wheels to avoid wheel slip.
