    Abstract: A method of operating a vehicle includes a vehicle controller receiving an operator-input vehicle control command with an associated torque request, and identifying any propulsion actuator constraints that limit a brake torque capacity available from the vehicle powertrain. Using the propulsion actuator constraint(s) and torque request, the controller determines a propulsion brake torque distribution for the vehicle's road wheels and a maximum brake torque capacity for the powertrain actuator(s). A first brake torque request is determined using the propulsion brake torque distribution and a vehicle control mode of the powertrain system, and a second brake torque request is determined using the maximum brake torque capacity and the vehicle control mode. A friction brake torque command is determined by arbitrating between the first and second brake torque requests. The vehicle controller transmits the friction brake torque command to the friction brake system and a powertrain brake command to the powertrain actuator(s).

    Abstract: A system and method of mitigating errors in a device includes a controller having a processor and tangible, non-transitory memory on which is recorded instructions. The propulsion source is configured to generate propulsion torque in response to a command by the controller. The controller is configured to determine if at least one predefined enabling condition is met. If at least one predefined enabling condition is met, then the controller is configured to determine if a speed of the device is at a target speed. Operation of the device is controlled based at least partially on the speed of the device. If the speed of the device is above or below the target speed, the controller is configured to determine a propulsion torque sufficient to bring the device to the target speed. The propulsion torque is delivered to the device via the propulsion source.

    Abstract: Method and systems for one-pedal driving (OPD) control for a vehicle. The methods and systems determine that regenerative braking is to be applied based on accelerator pedal stroke data, predict an upcoming deceleration event based on sensor data from a sensor system of the vehicle, thereby providing deceleration prediction data, adjust a default braking profile based on the deceleration prediction data, generate a regenerative braking command based on the accelerator pedal stroke data and the adjusted braking profile, and output the regenerative braking command to a motor/generator of the vehicle.

    Abstract: A road load module is configured to determine a road load torque to maintain zero vehicle acceleration. An initialization module is configured to determine an initial torque based on the road load torque. A closed loop (CL) module is configured to: when a CL state transitions from an inactive state to an active state, set a CL torque to the initial torque; and when the CL state is in the active state after transitioning to the active state, adjust the CL torque based on a difference between a target vehicle speed and a vehicle speed. A motor torque module is configured to determine a motor torque command based on the CL torque and a motor torque request determined based on an accelerator pedal position. A switching control module is configured to, based on the motor torque command, control switching of an inverter and apply power to an electric motor.

    Abstract: A method of operating a vehicle includes a vehicle controller receiving a driver acceleration/deceleration command for the vehicle's powertrain and determining a torque request corresponding to the driver's acceleration command. The controller shapes the torque request and determines compensated and uncompensated accelerations from the shaped torque request. The compensated acceleration is based on an estimated road grade and an estimated vehicle mass, whereas the uncompensated acceleration is based on a zero road grade and a nominal vehicle mass. A final speed horizon profile is calculated as: a speed-control speed profile based on the uncompensated acceleration if the vehicle's speed is below a preset low vehicle speed; or a torque-control speed profile based on a blend of the compensated and uncompensated accelerations if the vehicle speed exceeds the preset low vehicle speed. The controller commands the powertrain to output a requested axle torque based on the final speed horizon profile.
