Abstract: A driver assistance system aids a driver in charging one or more trailer-mounted batteries in a trailer being towed by an electrified passenger vehicle. Many existing charging facilities for electric vehicles have charging stalls with a layout configured to accommodate single vehicles. Charging facilities having drive-through or elongated charging stalls able to accommodate larger vehicles which are towing an electrified trailer are much scarcer. When attempting to charge a trailer-mounted battery in a charging stall meant for a single vehicle, it may be necessary to unhitch (i.e., decouple) the trailer while in the charging stall so that the passenger vehicle does not block the aisles of a charging station. Sensors in the vehicle perform a sensor sweep of a selected charging stall, and after unhitching, the trailer uses an independent drive system to park itself in the selected charging stall using driving commands which are calculated from the sensor sweep.

Abstract: This disclosure details exemplary traction battery pack venting systems for use in electrified vehicles. An exemplary traction battery pack system may include a venting system having one or more vent ducts for expelling battery vent byproducts from a battery pack. The vent ducts may include a thermal barrier configured to block heat emitted by the battery vent byproducts during cell venting events. In some embodiments, the thermal barrier includes a thermal barrier coating. In other embodiments, the thermal barrier includes both a thermal barrier coating and a thermal barrier layer. In still other embodiments, a second thermal barrier may be applied to vehicle components located near the battery pack for improving the thermal barrier properties.

Abstract: A system includes an illumination source operable at an adjustable duty cycle, a camera arranged to detect illumination from the illumination source, and a computer communicatively coupled to the illumination source and the camera. The duty cycle indicates a proportion of time that the illumination source is illuminated in a repeating pattern. The computer is programmed to operate the illumination source with the duty cycle at a baseline duty cycle in response to failing to detect an object having a preset type in image data from the camera, and operate the illumination source with the duty cycle at a high duty cycle in response to detecting the object having the preset type in the image data from the camera. The high duty cycle has the illumination source illuminated for a greater proportion of time than the baseline duty cycle.

Abstract: Systems and methods are configured for coordinating and providing passthrough charging during bidirectional energy transfer events between two or more electrified vehicles. The ability to pass charging power from one vehicle to another allows for multiple vehicles to be concurrently charged from a single charge source. Various passthrough charging strategies may be achieved with the proposed systems, including but not limited to, a distributed charging strategy, a waterfall charging strategy, a targeted charging strategy, an automated charging strategy, a pay-for-use charging strategy, etc.

Abstract: Methods and systems for diagnosing operation of an evaporative emissions system are described. The methods and systems may include increasing an amount of vacuum stored in an evaporative emissions system during discontinuously operating an engine in a boosted operating mode. Storing vacuum allows the evaporative emissions system to reach a desired vacuum level to verify absence of an evaporative emissions system breech.

Abstract: A plurality of images can be acquired from a plurality of sensors and a plurality of flattened patches can be extracted from the plurality of images. An image location in the plurality of images and a sensor type token identifying a type of sensor used to acquire an image in the plurality of images from which the respective flattened patch was acquired can be added to each of the plurality of flattened patches. The flattened patches can be concatenated into a flat tensor and add a task token indicating a processing task to the flat tensor, wherein the flat tensor is a one-dimensional array that includes two or more types of data. The flat tensor can be input to a first deep neural network that includes a plurality of encoder layers and a plurality of decoder layers and outputs transformer output. The transformer output can be input to a second deep neural network that determines an object prediction indicated by the token and the object predictions can be output.

Abstract: Systems and methods are described for electrical power control of a hybrid vehicle. A change in an electrical load of an ancillary component of the vehicle is determined. In response to determining the change in the electrical load of the ancillary component, an electrical load of an electrically heated catalyst of the vehicle is adjusted.

Abstract: A depletion amount of energy required to charge a user device connected to a device port of a vehicle is estimated based on a state of charge (SoC) of a device battery of the connected user device. Responsive to an expected SoC of a LV battery of the vehicle after providing the depletion amount of energy exceeding a calibrated threshold amount of energy of the LV battery, the connected user device is charged during key off. Otherwise, an engine start/stop schedule defining a time to start an engine of the vehicle and a duration of run time for the engine is utilized to generate additional energy to charge the connected user device to ensure the LV battery remains above the calibrated threshold amount of energy.
