Abstract: An electrified vehicle powered by a traction battery includes a coolant loop arranged to convey coolant through at least a radiator, a chiller, and the traction battery to transfer heat from the battery. The vehicle also includes a refrigerant loop in fluid communication with the chiller to selectively circulate refrigerant through the chiller to provide supplemental heat transfer from coolant conveyed through the chiller. The vehicle further includes a vision system having at least one camera with a field of view including a vicinity of the radiator and a controller programmed to detect a radiator coolant leak based on image data output from the vision system. The controller is also programmed to cause a bypass of the radiator within the coolant loop to stop conveyance of coolant through the radiator in response to detecting a coolant leak.

Abstract: A deviation hint is received from a vehicle by a server indicating an anomaly in vehicle sensor data compared to autonomous vehicle data maintained by the vehicle. A cause of the anomaly is identified per a view of the sensor data prior to through after the anomaly is received from the vehicle. Revised autonomous vehicle data is updated per the cause to a plurality of autonomous vehicles including the vehicle.

Abstract: A charge plate receiver assembly for an electric vehicle includes an inductive charge plate receiver and a swing arm pivotally secured to a mounting surface. The charge plate receiver is pivotally secured to the swing arm such that the charge plate receiver travels along an arc defined by a length of the swing arm when the assembly moves between a retracted position and a deployed position. When retracted, the charge plate receiver may retract into a cavity, defined by under-body components. The charge plate receiver has a planar surface and the planar surface is generally perpendicular to a horizontal plane of the vehicle in the retracted position and parallel with the horizontal plane of the vehicle in the deployed position.

Abstract: Exposure to ultrasound energy emitted by remote object detection systems on vehicles is reduced for vehicle occupants. An automotive vehicle has a passenger cabin and a remote sensing system including ultrasonic transceivers mounted for sensing external objects. An ultrasonic microphone is disposed to sense an ultrasonic wave entering the passenger cabin at greater than 30 kHz. An antinoise processor calculates an antinoise signal adapted to at least partially cancel the ultrasonic wave at a predetermined location in the cabin. An amplifier is coupled to the processor for amplifying the antinoise signal by a predetermined gain. An ultrasonic speaker is coupled to the amplifier to project the antinoise signal into the predetermined location to attenuate the ultrasonic wave at the predetermined location.

Abstract: Remote object detection in an automotive vehicle includes an ultrasonic sensor for emitting ultrasonic bursts from an ultrasonic transducer at a standard rate. At least one object is tracked which reflects the ultrasonic bursts to the sensor. The transducer is adaptively set to emit ultrasonic bursts at a reduced rate which is less than the standard rate based on a result of the object tracking. In one embodiment, the ultrasonic bursts are set at the reduced rate when the tracked object is maintaining a stable relative position. The stable relative position may be comprised of the tracked object having a relative velocity less than a threshold. In another embodiment, extrinsic ultrasonic bursts originating from the tracked object and subsequent echoes between the automotive vehicle and the tracked object can be used by the vehicle to monitor the tracked object while emission of bursts from the vehicle are switched off.

Abstract: A hybrid electric vehicle having one or more controllers, at least two axles independently driven by respective electric machines (EMs) that are each coupled to a separate battery, and a combustion engine (CE) coupled to one of the axles. At least one of the controller(s) are configured to deliver power to one of the axles in a single axle drive mode, and in response to a torque demand signal (TDS) exceeding a single axle power limit, to deliver power to another axle, and/or all axles. The controller(s) are further configured to respond to the TDS exceeding a multiple axle power limit, and to deliver additional CE power to the coupled axle. In response to a braking signal, the controller(s) may also adjust at least one of the EMs to capture mechanical braking energy from a respective axle, and generate negative torque to charge one or more of the separate batteries.

Abstract: A method for controlling an electric rear axle drive (eRAD) includes, responsive to a vehicle being in DRIVE, operating the eRAD such that any torque output by the eRAD to drive rear wheels forward is less than torque output to drive front wheels forward. The method further includes, responsive to the vehicle being in REVERSE, operating the eRAD such that torque output by the eRAD to drive the rear wheels backwards is more than any torque output to drive the front wheels backwards.
