Abstract: A system and method for adaptation of electric vehicle charging communication parameters that includes commencing, by an electric vehicle (EV), a communication session between the EV and an electric vehicle supply equipment (EVSE) charging station. The communication session includes extracting a vehicle charging communication session parameter from the EVSE charging station and validating, by the EV, that the vehicle charging communication session parameter with a default charging parameter. A direct current or an alternating current charging of the EV, based on a digital communication parameter received by the EVSE charging station, is initiated. In the event of a failure of the communication session, the vehicle charging communication session parameter is relaxed and a restarted EV charging session is initiated, where if the restarted EV charging session is successful, a deviation parameter is generated.

Abstract: A system includes a compressor outlet temperature module, a refrigerant quality module, and a correction factor module. The compressor outlet temperature module is configured to estimate a temperature at an outlet of a compressor in a thermal system of an electric vehicle. The refrigerant quality module is configured to estimate a quality of refrigerant at an inlet of the compressor based on an enthalpy at the compressor inlet and an inlet enthalpy correction factor. The refrigerant quality is a ratio of vapor refrigerant mass to total refrigerant mass. The correction factor module is configured to determine the inlet enthalpy correction factor based on the estimated compressor outlet temperature and a temperature measured at the compressor outlet.

Abstract: A warning system is provided for alerting a Vulnerable Road User (VRU) of a predicted collision. The system includes one or more input devices for transmitting a first input signal associated with a first vehicle positioned in a first lane, a second input signal associated with a second vehicle positioned in a second lane, and a third input signal associated with the VRU located on a crosswalk that extends across the first and second lanes. The system further includes a computer having a processor and a non-transitory computer readable medium. The processor is programmed to determine the predicted collision between the second vehicle and the VRU at a predicted collision site. The processor is further programmed to generate an actuation signal. One or more roadway notification devices notify the VRU that the second vehicle is positioned in the second lane and headed toward the predicted collision site in the crosswalk.

Abstract: Systems and methods systems provide for client control over an Autonomous Vehicle (AV). The AV can determine sets of mechanical operations that it can take at a future time. The AV can determine a ranking for each of the sets of mechanical operations, including a first ranked set and at least one second ranked set. Client or user selection can be given a certain score, weight, or other value. The AV can apply the value to the second ranked set to determine an adjusted ranking. If the adjusted ranking outranks a ranking of the first ranked set, then the AV can expose the first ranked set and the second ranked set to a client interface. If the AV receives a selection of the second ranked set, the AV can perform that set of mechanical operations. Otherwise, the AV can perform the first ranked set of mechanical operations.
Abstract: A vehicle includes an electric motor and a battery operable to provide electrical power to the electric motor. The battery system includes a first battery pack and a second battery pack. The first battery pack has a relatively high power density, and the second battery pack has a relatively high energy density. An electronic controller determines a remaining driving range of the first battery pack, and a remaining driving range of the second battery pack. The vehicle has a human-machine interface (HMI) operatively connected to the electronic controller and configured to indicate the remaining driving range of the first battery pack and the remaining driving range of the second battery pack. The controller executes a method of monitoring the battery system.
Abstract: A positive electrode including a plurality of electroactive particles defining an electroactive layer is provided. A first lithium-containing coating is disposed on one or more surfaces of the electroactive layer. The first lithium-containing coating covers between about 30% and about 50% of a total exposed surface area of the electroactive layer. A second lithium-containing coating encompasses at least one electroactive particle of the plurality of electroactive particles. The second lithium-containing coating covers between about 95% and about 100% of the at least one electroactive particle. The first and second lithium-containing coatings each have a thickness between about 0.2 nm and about 5 nm. The positive electrode further includes an electrolyte additive that aids in the formation of a first passivation layer on exposed surfaces of the first lithium-containing coating, and a second passivation layer on exposed surfaces of the second lithium-containing coating.

Abstract: Various technologies described herein pertain to causing presentation on a user interface of an immediate portion of a navigation route of an autonomous vehicle. A computing system of the autonomous vehicle determines whether an object detected by sensor(s) of the autonomous vehicle proximate to the immediate portion of the navigation route are of a type and relative position defined as one of consequential and inconsequential for a human passenger. In response to determining that an object has both a type and relative position defined as consequential, the computing system causes presentation on the user interface a representation of the object relative to the immediate portion of the navigation route to provide a confidence engendering indication that the autonomous vehicle has detected the object. Otherwise if inconsequential, presentation on the user interface of any representation of the object is not caused by the computing system to avoid creating a confusing presentation.

Abstract: An electronic pallet (e-pallet) includes a superstructure mounted to a wheeled base platform. A tether device defines an articulation angle with respect to a leading edge of the superstructure, and is grasped by an operator towing the e-pallet. A motor connected to driven road wheels transmits a drive torque to the road wheels responsive to motor control signals, including a desired yaw rate and ground speed. A speed sensor, angle sensor, and length sensor are respectively configured to determine an actual ground speed of the e-pallet, the articulation angle, and a length of the tether device. An electronic controller, in response to the input signals, generates the motor control signals using proportional-integral-derivative (PID) control logic. Coupled lateral and longitudinal dynamics control loops respectively determine the desired yaw rate and ground speed to accommodate for motion of the operator.
