Abstract: A vehicle includes a powertrain and a controller. The powertrain has an engine and an electric machine. The controller is programmed to, for so long as a catalytic converter temperature is less than a threshold, maintain a steady state engine torque output and adjust an electric machine torque output to satisfy driver demand. The controller is further programmed to, responsive to the catalytic converter temperature exceeding the threshold, permit adjustments of the engine torque output to satisfy the driver demand.

Abstract: A vehicle high voltage system may include switches (e.g., IGBTs, contactors, relays, etc.), wires, a traction battery, electrical components with electrical properties and at least one controller. The at least one controller may be programmed to modulate a switch to provide a testing voltage for the electrical components, which is less than an operating voltage of the battery, and in response to a current flow associated with the testing voltage being less than a predetermined threshold, stop current flow between the battery and electrical components.

Abstract: A hybrid vehicle includes an engine, a traction motor, a battery, and a controller. The controller is programmed to, responsive to the engine achieving maximum torque capacity while the engine and motor operate to completely satisfy a demand that exceeds the maximum torque capacity, maintain the engine at the maximum torque capacity and reduce torque output of the motor to a non-zero value such that the engine and motor do not operate to completely satisfy the demand.

Abstract: According to one embodiment of this disclosure, a vehicle having an electric machine and at least one controller is described. The electric machine may be configured to generate creep torque to move the vehicle. The controller may be programmed to decrease a target speed of a torque converter impeller to create a desired brake torque and partially cancel the creep torque without application of friction brakes in response to a brake pedal being pressed while an accelerator pedal is not being pressed.

Abstract: A driver coaching system may have an input device generating an input signal indicative of a road condition. The system may also include an advisory device determining an output conveyed to a driver and indicative of a fuel efficiency rating based on an actual vehicle speed and an optimum fuel efficient speed. The advisory device may not decrease the fuel efficiency rating when the road condition does not warrant the optimum fuel efficient speed.

Abstract: A vehicle includes a battery, an electric machine, an electrical outlet, and a controller. The electric machine is configured to charge the battery. The electrical outlet is configured to draw power from the battery to power an external device. The controller is programmed to adjust a rate at which the electric machine charges the battery based on a power consumption at the electrical outlet exceeding a threshold and a battery degradation value.

Abstract: A hybrid electric vehicle or a battery electric vehicle has an electric machine, a traction battery, and an accessory powered by the traction battery. The vehicle includes a controller that, in response to a driver lifting their foot off the accelerator pedal, increases the negative motor torque produced by the electric machine for charging the traction battery to compensate for a load applied by the accessory. The controller increases negative motor torque as limited by a maximum motor torque limit. The accessory may be an electric air conditioning compressor and/or a DC/DC inverter.

Abstract: A vehicle powertrain includes a DC-DC converter and a controller. The DC-DC converter is coupled between a traction battery and an inverter for an electric machine. The controller is configured to, in response to a rotational speed of the electric machine dropping below a back EMF threshold speed, transition to a current control based six step inverter mode and operate the DC-DC converter to output a voltage less than an open circuit voltage of the traction battery.

Abstract: A voltage converter includes a switch having a switching loss that decreases as a switching frequency of the switch decreases. The voltage converter further includes a controller programmed to vary the switching frequency based on a duty cycle of the switch and a current input to the switch to reduce switching losses or reduce a ripple current magnitude.
