Abstract: A system and method for controlling a hybrid electric vehicle during regenerative braking is provided. The system and method include a brake controller adapted to cause, for a selected transmission gear, a first torque ratio to be applied to a regenerative brake system during regenerative braking and a second torque ratio, different from the first torque ratio, to be applied when the vehicle is not regenerative braking. The first torque ratio results in an increased braking torque generated by the regenerative brake system compared with application of the second torque ratio.

Abstract: A control system for a modular hybrid electric vehicle operates an internal combustion engine at a torque level above the driver demanded torque improving the engine's efficiency. A traction motor driveably connected to the engine is operated at a torque level such that the combined torque satisfies the driver demand. The traction motor torque is limited to avoid inefficient combinations of speed and torque at which the motor is inefficient. During idle operation, the traction motor is operated at a torque determined from a battery state of charge and the engine is operated to maintain a predetermined speed. If the engine speed drops below a threshold, motor torque is adjusted to reduce the load on the engine to avoid stalling.

Abstract: A vehicle includes a battery, an electric machine, and a controller. The battery has a state of charge. The electric machine is configured to draw electrical power from the battery to propel the vehicle in response to an acceleration request and to deliver electrical power to the battery to recharge the battery. The controller is programmed to adjust an estimation of battery state of charge based on a feed forward control that includes a coulomb counting algorithm, a first feedback control that includes a first battery model, and a second feedback control that includes a second battery model. The controller is further programmed to control the electrical power flow between the battery and the electric machine based on the estimation of the state of charge of the battery.

Abstract: A traffic controller includes a controller configured to reject a request and issue a speed requirement based on a priority to cause a speed of a one of a plurality of vehicles to be within a speed band before entering a road. The rejection is responsive to receiving the speed request from the one approaching the road having priority less than a predetermined threshold and outside of a speed band and a predetermined acceleration band of vehicles on the road.

Abstract: Methods and systems are provided for improving engine restart operations occurring during a transmission shift in a hybrid vehicle. Engine speed is controller during cranking and run-up to approach a transmission input shaft speed that is based on the future gear of the transmission shift. Engine speed is controlled via adjustments to spark, throttle, and/or fuel, to expedite engine speed reaching the synchronous speed.

Abstract: An autonomous vehicle includes an electric powertrain having an electric machine and a traction battery. A vehicle controller is programmed to command power to the electric machine to propel the vehicle along a segment of a route according to a predetermined speed profile that is derived from a predicted heat generation of the battery for the segment such that actual temperatures of the battery remain below a temperature threshold for the segment.

Abstract: In at least one embodiment, a vehicle powertrain includes an engine and an electric machine mechanically coupled by a clutch. The powertrain also includes a torque converter configured to fluidly couple the electric machine to an output shaft. A controller is programmed to command a rotational speed output of the electric machine to the torque converter based on a predicted torque delivered across the clutch. The controller is further programmed to modify the command based on a difference between the commanded rotational speed output and an actual rotational speed output of the electric machine.

Abstract: A table of engine torque correction factors is used to compensate for noise factors. In a hybrid vehicle, the motor is used to measure engine torque during periods of constant transmission input shaft torque. By comparing the measured input torque to the requested engine torque, a controller can update the table of correction factors to compensate for changes in the noise factors. A service procedure may be implemented that systematically provides the controller an opportunity to update many values in the table.

Abstract: A hybrid electric vehicle having a powertrain including an engine and an electric machine, and controllers configured to derate powertrain output torque below a nominal maximum to a fault-torque limit, in response to a vehicle fault or issue. The vehicle and controllers are also configured to transiently increase powertrain torque output above the fault-torque limit in response to a torque demand that exceeds the limit, and which is needed to enable a predicted vehicle maneuver. The controller also establishes a predicted duration for the predicted interim vehicle maneuver and for override of the fault-torque limit and delivery of the additional torque from the torque-demand signal and other signals. The predicted duration includes a time span to maneuver through roadway obstacles and traffic, but does not exceed a limited operation time or a limited power output established by the controller from the vehicle issue or fault identified by the fault signal.
