Abstract: Vehicle costs may be allocated between users of a vehicle, including autonomous vehicles. A vehicle cost allocation (VCA) computing device receives vehicle telematics data associated with trips performed by vehicle users using a vehicle. The VCA computing device is also configured to determine one or more vehicle costs associated with the trip based upon the vehicle telematics data. The vehicle costs may include usage-based or trip-based insurance. The VCA computing device is also configured to determine a respective portion of the vehicle cost to each of the one or more vehicle users, access a respective pre-paid account associated with each vehicle user, and transmit instructions to a respective financial institution associated with each pre-paid account to withdraw funds corresponding to the respective portion of the total vehicle cost.

Abstract: Systems and methods for operating a vehicle that may be driven to or sold in different geographical locations that may have different engine emissions and fuel economy standards are described. The systems and methods may adjust vehicle operation to comply with standards that may be enforced where the vehicle is geographically located. The standards may apply to countries, treaty zones, race track areas, off-road areas, and other geographically related standards.

Abstract: Systems and methods for operating an internal combustion engine are described. In one example, an engine's position is adjusted during engine stopping so that the engine may be less likely to stop at a crankshaft angle where rotating a fuel pump may increase engine cranking torque due to work performed by the fuel pump.

Abstract: Methods and systems are provided for identifying degraded exhaust gas temperature (EGT) sensor responses. In one example, a method may include cycling an engine between a higher temperature operating mode and a lower temperature operating mode while maintaining engine torque output across the higher temperature operating mode and the lower temperature operating modes, both the higher temperature operating mode and the lower temperature operating mode providing stoichiometric exhaust gas to a downstream catalyst, and characterizing a response behavior of an EGT sensor based on output of the EGT sensor during the cycling. In this way, stepwise exhaust gas temperature changes are produced for characterizing the EGT sensor response without disrupting emissions and torque control.

Abstract: A vehicle propulsion system includes an engine arranged to output a first torque to a driveshaft and an electric motor arranged to output a second torque to the driveshaft. The vehicle also includes an automatic transmission arranged to receive an input torque from the driveshaft. The vehicle further includes an exhaust system to output combustion byproduct from the engine. A vehicle controller is programmed to, during deceleration, cause the engine to apply a negative first torque to increase an audible exhaust system sound. The controller is also programmed to activate the electric motor to output a positive second torque such that the input torque to the automatic transmission does not exceed a transmission torque threshold during deceleration.

Abstract: Vehicle costs may be allocated between users of a vehicle, including autonomous vehicles. A vehicle cost allocation (VCA) computing device receives an anticipated trip report associated with an anticipated future trip, the anticipated trip report associated with at least one vehicle user including an anticipated driver of the vehicle and an anticipated passenger, the anticipated trip report including at least one of an anticipated destination and a distance of the anticipated future trip. The VCA computing device is also configured to determine one or more anticipated vehicle costs for the anticipated future trip. The vehicle costs may include usage-based or trip-based insurance. The VCA computing device is also configured to allocate a respective portion of the vehicle cost to the anticipated driver and passenger and transmit the anticipated vehicle costs to for review by the anticipated driver.

Abstract: Methods and systems are provided for cycle-to-cycle torque reductions under exhaust component temperature constraints. In one example, a method may include, responsive to a torque reduction request, introducing a lambda split between two sets of cylinders over a plurality of engine cycles while maintaining an average of stoichiometry between the two sets of cylinders, and, responsive to reaching a lambda split threshold, introducing differentially delayed ignition timing in both sets of cylinders. In this way, fast torque reduction may be provided while maintaining a globally stoichiometric air-fuel ratio, thereby decreasing vehicle emissions, and reducing heat-related degradation to exhaust components.

In one example, three different signals are input to a weighted average filter to determine the presence or absence of belt slip so that quality of an indication of belt slip may be improved.

In one example, clutches of a transmission are operated to provide a desired load to the engine so that engine combustion stability may be improved while supplying heat to a catalyst so that the catalyst light off time may be reduced.

Abstract: Methods and systems are provided for enhancing and delivering engine sounds to a vehicle cabin based on a selected mode. In one example, a method may include adjusting openings of one or more valves fluidically coupling one or more corresponding engine regions to a sound tube of a sound enhancing system based on the selected mode. Throttle opening may also be adjusted to compensate for air routed from the engine regions to the sound tube instead of flowing to the engine cylinders.

Abstract: Methods and systems are provided for diagnosing an actuator of a variable inlet compressor coupled in an electric turbocharger. During torque transitions, an electrical power consumption of an electric boost assist motor is observed and used to infer an actual compressor speed and pressure ratio across the compressor. By comparing the measured pressure ratio to a compressor map, it may be determined if the actuator is stuck open or stuck closed.

Abstract: Embodiments of the invention include a method and a device for increasing blood flow and controlling the temperature of a mammal by applying a desired pressure to extremities of a mammal. The device generally includes a pliant body element that is adapted to receive a portion of an extremity of the mammal therein, and then apply a pressure to a portion of the extremity when a pressure is provided to a region in which the extremity is positioned within the pliant body element. By evacuating the region in which the extremity is enclosed, a contact surface area between the extremity of a mammal and the pliant body element is increased, due to the external atmospheric pressure acting on the pliant body element against the skin of the extremity of the mammal. The application of pressure assures that sufficient contact and thermal heat transfer (heating or cooling) is provided to the extremity of the mammal.
