A fuel cell and battery power management system for a fuel cell-powered vehicle includes an electric traction motor, a traction battery in electrical communication with the electric traction motor, a fuel cell stack in electrical communication with the traction battery and the electric traction motor, and a vehicle control system. The vehicle control system is configured to operate the vehicle with at a first discharge power level and a first charging power level if fuel cell power is sufficient alone to navigate the uphill grade and to build up battery state of charge by charging the traction battery at a second charging power level when the vehicle is approaching an uphill grade if fuel cell power is not sufficient alone to navigate the uphill grade. The vehicle control system is further configured to initiate proactive depletion of the battery SOC to enable powertrain braking and to provide regenerative power.

Predictive fuel cell and battery power management for high sustained load conditions

Methods and systems are described for controlling output of a fuel cell that generates electrical power for an electric machine that propels a vehicle. In one example, a driver demand power reduction is anticipated and output of the fuel cell is adjusted before the driver demand power is reduced so that a greater amount of electric charge may be stored in an electric energy storage device.

Methods and system for operating a fuel cell vehicle

A vehicle includes an electric machine and a controller. The controller is programmed to, in response to releasing an accelerator pedal during a first driving scenario that is based on a first set of navigation data, increase regenerative braking torque of the electric machine to a first value. The controller is further programmed to, in response to releasing the accelerator pedal during a second driving scenario that is based on a second set of navigation data, increase the regenerative braking torque of the electric machine to a second value that is less than the first value.

Regenerative braking control system for a hybrid or electric vehicle

A vehicle includes a powertrain and a controller. The powertrain has an engine and an electric machine that are each configured to generate power within the powertrain to propel the vehicle. The controller is programmed to, generate a powertrain power output profile required to propel the vehicle over a predetermined route based on navigation data. The controller is further programmed to, in response to the electric machine operating to propel the vehicle over the predetermined route while the engine is shutdown and an upcoming increase in the powertrain power output profile to a value that is greater than a threshold, initiate an engine start at a predetermined time period before the upcoming increase in the powertrain power output profile.

Engine start control system for a hybrid vehicle

A vehicle includes an engine, a wireless transceiver that receives attribute data, and a controller. The controller selectively shuts down the engine responsive to such requests based on whether a predicted fuel savings associated with a predicted engine off duration is greater than a predicted fuel usage to restart the engine.

Method and system for controlling vehicle engine pull-down

Methods and system are provided for generating regenerative braking torque at a front axle and a rear axle of a vehicle. In one example, the regenerative braking torque may be a function of a normal load applied to the front axle and a normal load applied to the rear axle.

System and method for improving traction of a vehicle that includes two electric machines

A method and system for operating a vehicle that includes a plurality of engine starting devices and an internal combustion engine is described. In one example, the method selects one of a plurality of engine starting devices to start an engine based on durability metrics of each of the plurality of engine starting devices. In addition, engine starting device selection may be based on calibration parameters that are generated via a server that is external to the vehicle.

Methods and system for adaptively switching an engine starting device

Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, an electric machine, an integrated starter/generator, and a transmission are described. In one example, transmission output torque and electric machine torque are adjusted while a brake pedal and accelerator pedal are contemporaneously applied.

Methods and system for operating a hybrid vehicle

Methods and systems are provided for operating a driveline of a four wheel drive vehicle that includes a high gear ratio and a low gear ratio. The driveline may be operated to shift between the high gear ratio and the low gear ratio while the four wheel drive vehicle is moving. In one example, a clutch is opened during shifting from the high gear ratio to the low gear ratio, which allows the vehicle to continue traveling during the gear ratio change.

Methods and system for operating a four wheel drive electric vehicle

Methods and systems for operating a driveline that includes one or more electric machine providing torque to one or more axles are described. In one example, a requested vehicle speed is adjusted responsive to at least one of vehicle yaw, vehicle roll, and vehicle pitch so that vehicle speed may be maintained at a requested value.

Methods and system for operating a vehicle

This disclosure details electrified vehicles that are equipped with secondary battery packs for increasing the electric range of the vehicles. An exemplary electrified vehicle includes a cargo space, such as a truck bed, and a secondary battery pack positioned within the cargo space. The secondary battery pack is adapted to selectively supply power for propelling one or more vehicle drive wheels. In some embodiments, the secondary battery pack is shaped like, and therefore disguised as, a toolbox.

Electrified vehicles equipped with secondary battery packs

Methods and systems for operating a driveline that includes a dual clutch transmission are described. In one example, clutches of the dual clutch transmission may be cooled via activating and adjusting a flow rate of an electric pump. Further, driveline operating modes may be entered or exited in response to clutch operating conditions so that driveline robustness may be enhanced.

Methods and system for operating a driveline

Methods and systems are provided for operating a hybrid vehicle during operating conditions where vehicle braking is requested. In one example, regenerative braking is allocated to vehicle wheels responsive to actual and estimated vehicle yaw. Additionally, friction braking torque is allocated to vehicle wheels responsive to requested braking torque and regenerative braking torques.

Regenerative vehicle braking with wheel slip control and yaw stability control

A vehicle includes an electric machine, a detachable lift, and a controller. The detachable lift has a lift battery that is electrically connected to the electric machine. The controller is programmed to, responsive to the vehicle traveling on a predetermined route, transfer power between the electric machine and lift battery such that a lift battery charge is within a desired range at an end of the route.

Hybrid vehicle system

A vehicle includes a pair of electric machines each coupled to a laterally-opposing wheel to output a wheel torque. The vehicle also includes a controller programmed to command a combined regenerative braking torque output of the electric machines based on a lesser of a braking torque limit of each individual electric machine. The controller is also programmed to command a regenerative braking torque from each electric machine to be within a predetermined torque threshold of each other in response to a yaw rate exceeding a yaw threshold.
