Abstract: A system and method for controlling a transmission gear shift during a braking event in a vehicle having an electric motor and friction brakes both operable to brake the vehicle includes the step of reducing friction braking to increase wheel torque during the braking event. The braking event includes both friction braking and regenerative braking. The reduction in friction braking to increase the wheel torque is based at least in part on a reduction in the wheel torque resulting from a change in gear ratio of a step-ratio transmission during the transmission gear shift.

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 an electric machine, a starter-generator, and a controller. The electric machine is coupled to a traction battery via an inverter. The starter-generator is mechanically coupled with an engine and electrically coupled with a low-voltage battery. And, the controller charges the low-voltage battery with power from the traction battery, and in response to a torque demand of the electric machine falling below a threshold defined by losses of the inverter, transitions to the starter-generator to charge the low-voltage battery.

Abstract: Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods adjust battery charging and discharging as well as engine and motor torque based on whether or not the vehicle is operating in a cruise control mode. In one example, curves that provide a basis for operating an engine and motor based on driver demand torque are compressed during a vehicle cruise control mode to improve powertrain efficiency.

Abstract: An exemplary method includes circulating a fluid through a heat exchanger and a battery pack when the battery pack requires cooling, and circulating the fluid through an exhaust gas heat recovery device and the battery pack when the battery pack requires heating. An exemplary system includes a battery pack, a heat exchanger, an exhaust gas heat recovery device, and a fluid valve moveable to a cooling position that permits a fluid to circulate between the heat exchanger and the battery pack and a heating position that permits the fluid to circulate between the exhaust gas heat recovery device and the battery pack.
