Abstract: A vehicle includes an electric motor and an engine selectively coupled to the electric motor. The vehicle has an electric motor controller configured to, in response to (i) an absence of receiving a motor command signal within a predetermined time, (ii) a battery voltage being below a first threshold and (iii) a motor speed exceeding a second threshold, restrict operation of the electric motor to a limited operating mode and control the electric motor to generate a charging torque for a battery.

Abstract: A vehicle charging system includes a charger configured to receive power form an external power source and a connector. The connector is configured to receive power from the charger and transmit the received power to a vehicle via a high-voltage cable. The cable is configured to connect the connector to a vehicle battery. Each of the charger and the connector includes a high voltage interlock loop (HVIL) configured to cause the charger to cease power transfer upon recognizing a predetermined voltage difference at a pair of ports of the HVIL.

Abstract: A method of managing torque at a vehicle standstill includes outputting torque from a powertrain to satisfy a driver torque demand. The method also includes, in response to a nonzero torque demand resulting in vehicle standstill, applying a friction brake to maintain the vehicle standstill and substantially reducing output torque of the powertrain during friction brake application. The method further includes satisfying driver torque demand using the powertrain and releasing the friction brake in response to the driver torque demand deviating from the nonzero torque demand by more than a predetermined amount.

Abstract: A vehicle may include at least one electric machine, a traction battery, and a voltage boost converter electrically connecting the at least one electric machine and traction battery. The vehicle may further include at least one controller programmed to, in response to a request for drive mode while in a passive neutral mode, enable the boost converter and drive an output voltage of the boost converter to a predetermined target. The controller may be further programmed to, in response to the output voltage achieving the predetermined target, enable the at least one electric machine and drive a current through the at least one electric machine to zero such that an output torque of the at least one electric machine is approximately zero; and in response to the current achieving approximately zero, increase the current through the at least one electric machine such that the output torque is greater than zero.

Abstract: A vehicle includes an accelerator pedal, an electric machine, and a controller. The electric machine is configured to propel and brake the vehicle according to a one-pedal driving operation. The controller is programmed to, in response to depressing the accelerator pedal, command a desired torque to the electric machine. The controller is further programmed to, adjust the desired torque based on a gradient of a road surface that the vehicle is positioned on. The controller is further programmed to, in response to movement of the electric machine in a direction that is opposite to a desired direction while the adjusted desired torque is being applied, increase the adjusted desired torque by a compensation torque such that movement of the electric machine transitions to the desired direction.

Abstract: A method for controlling an engine in a hybrid electric vehicle according to the present disclosure includes, in response to a drive motor being unavailable, commanding an engine power equal to the lesser of a first and a second power. The first power is sufficient to satisfy a driver wheel torque request at the current engine speed, and the second power corresponds to a maximum engine torque available at a target engine speed, where the target engine speed is selected to attain a desired battery state of charge.
